• Wordpress Permissions OS X & MAMP

  - by Matt2020

  I have installed several local versions of Wordpress for development purposes. After the install I can create posts, pages and edit admin options. However as soon as try to upload images which would be saved in wp_content/uploads I get an error: Upload Error: Unable to create directory ...../blog/wp-content/uploads/2011/05. Is its parent directory writable by the server? Looks like MAMP server runs as user _www The blog directory is owned by User1 and the group User1 _www is not in the User1 group, should it be? I do not want to chmod 777 or 765 on the directories just to get it going. Googled up a couple of references: http://codex.wordpress.org/Changing_File_Permissions in "Permission Scheme for WordPress" All files should be owned by your user (ftp) account on your web server, and should be writable by that account. On shared hosts, files should never be owned by the webserver process itself (sometimes this is www, or apache, or nobody user). Any file that needs write access from WordPress should be owned or group-owned by the user account used by the WordPress (which may be different than the server account). For example, you may have a user account that lets you FTP files back and forth to your server, but your server itself may run using a separate user, in a separate usergroup, such as dhapache or nobody. If WordPress is running as the FTP account, that account needs to have write access, i.e., be the owner of the files, or belong to a group that has write access. In the latter case, that would mean permissions are set more permissively than default (for example, 775 rather than 755 for folders, and 664 instead of 644). User and group are User1 (which is admin). Running "ps aux | grep httpd" is running as _www So I think this means Wordpress is running as user _www. So the advice seems contradictory: "files should never be owned by the webserver process" i.e. _www but then later it says "Any file that needs write access from WordPress should be owned or group-owned by the user account used by the WordPress" So isn't this _www again? Another search found this url http://dancingengineer.com/computing/2009/07/how-to-install-wordpress-on-mac-os-x-leopard States Which says: My preferred way to do this is to change the group of the wordpress directory and its contents to _www and give write permissions to the group. Keep the owner as your "username". $ cd /Users/"username"/Sites $ sudo chown -R username:_www wordpress_directory $ sudo chmod -R g+w wordpress_directory However, when I tried this, it did not work for automatic upgrades to newer versions of WordPress although it worked for automatically updating the .htaccess file for pretty permalinks. It is not entirely clear to me what should be done. This last suggestion seems to be saying change the group from User1 to _www and give the group write access, but Wordpress upgrades won't work. Is this the right solution? I would have thought there would be a clear way to set this up on OS X 10.6? Be great if there was a plugin that could run a script for each of the main OS's that Wordpress runs on.

• Has this server been compromised?

  - by Griffo

  A friend is running a VPS (CentOS) His business partner was the sysadmin but has left him high and dry to look after the system. So, I've been asked to help out in fixing an apparent spam problem. His IP address got blacklisted for unsolicited mail. I'm not sure where to look for a problem, but I started with netstat to see what open connections were running. It looks to me like he has remote hosts connected to his SMTP server. Here's the output: Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 78.153.208.195:imap 86-40-60-183-dynamic.:10029 ESTABLISHED tcp 0 0 78.153.208.195:imap 86-40-60-183-dynamic.:10010 ESTABLISHED tcp 0 1 78.153.208.195:35563 news.avanport.pt:smtp SYN_SENT tcp 0 0 78.153.208.195:35559 vip-us-br-mx.terra.com:smtp TIME_WAIT tcp 0 0 78.153.208.195:35560 vip-us-br-mx.terra.com:smtp TIME_WAIT tcp 1 1 78.153.208.195:imaps 86-40-60-183-dynamic.:11647 CLOSING tcp 1 1 78.153.208.195:imaps 86-40-60-183-dynamic.:11645 CLOSING tcp 0 0 78.153.208.195:35562 mx.a.locaweb.com.br:smtp TIME_WAIT tcp 0 0 78.153.208.195:35561 mx.a.locaweb.com.br:smtp TIME_WAIT tcp 0 0 78.153.208.195:imap 86-41-8-64-dynamic.b-:49446 ESTABLISHED Does this indicate that his server may be acting as an open relay? Mail should only be outgoing from localhost. Apologies for my lack of knowledge but I don't work on linux in my day job. EDIT: Here's some output from /var/log/maillog which looks like it may be the result of spam. If it appears to be the case to others, where should I look next to investigate a root cause? I put the server IP through www.checkor.com and it came back clean.

• Set up lnux box for hosting a-z [apache mysql php ssl]

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP: To upgrade PHP to the latest version, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! cd /tmp #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm #rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm #rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. [will list all packages available in the IUS repo] rpm -qa | grep php [will list installed packages needed to be removed. the installed packages need to be removed before you can install the IUS packages otherwise there will be conflicts] #yum shell >remove php-gd php-cli php-odbc php-mbstring php-pdo php php-xml php-common php-ldap php-mysql php-imap Setting up Remove Process >install php53 php53-mcrypt php53-mysql php53-cli php53-common php53-ldap php53-imap php53-devel >transaction solve >transaction run Leaving Shell #php -v PHP 5.3.2 (cli) (built: Apr 6 2010 18:13:45) This process removes the old version of PHP and installs the latest. To upgrade mysql: Pretty much the same process as above with PHP #/etc/init.d/mysqld stop [OK] rpm -qa | grep mysql [installed mysql packages] #yum shell >remove mysql mysql-server Setting up Remove Process >install mysql51 mysql51-server mysql51-devel >transaction solve >transaction run Leaving Shell #service mysqld start [OK] #mysql -v Server version: 5.1.42-ius Distributed by The IUS Community Project And this is where I'm at. I will keep editing this as I make progress. Any tips on how to Configure Virtualhosts for SSL, setting up a CA, setting up SFTP with openSSH, or anything else would be appreciated.

• PHP, Apache and curl: Differences between Windows and Linux?

  - by beginner_

  I'm trying to run my php App on Ubuntu Server 11.10. This App works fine under Apache + PHP in windows. I have other applications that I can simply copy&paste between the 2 OS and they work on both. (These don't use cURL). However this one uses the php library tonic (RESTful webservices) and makes us of php cURL module. The issue is I'm not getting an error message which makes it impossible to find the issue. I (must) use NTLM authentication and this is done with AuthenNTLM Apache Module: Order allow,deny Allow from all PerlAuthenHandler Apache2::AuthenNTLM AuthType ntlm AuthName "Protected Access" require valid-user PerlAddVar ntdomain "domainName server" PerlSetVar defaultdomain domainName PerlSetVar ntlmsemtimeout 2 PerlSetVar ntlmdebug 1 PerlSetVar splitdomainprefix 0 All files that cURL needs to fetch override AuthenNTLM authentication: order deny,allow deny from all allow from 127.0.0.1 Satisfy any Since these files are only fectehd by cURL from same server, access can be limited to localhost. Possible issues are: NTLM auth isn't overridden for files requested through cURL (even though AllowOverride All is set) curl works differently on linux $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIE, $strCookie); curl_setopt($ch, CURLOPT_URL, $baseUrl . $queryString); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $html = curl_exec($ch); curl_close($ch); other? Apache log says: [error] Bad/Missing NTLM/Basic Authorization Header for /myApp/webservice/local/viewList.php But this directory should override NTLM authentication using curl command line from windows to access same resource i get: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html> <head> <title>406 Not Acceptable</title> </head> <body> <h1>Not Acceptable</h1> <p>An appropriate representation of the requested resource /myApp/webservice/myResource could not be found on this server.</p> Available variants: <ul> <li><a href="myResource.php">myResource.php</a> , type application/x-httpd-php</li> </ul> <hr> <address>Apache/2.2.20 (Ubuntu) Server at localhost Port 80</address> </body> </html> Note: This is duplicate from http://stackoverflow.com/questions/9821979/php-curl-on-linux-what-is-the-difference-to-curl-on-windows Is it was suggested I post it here. EDIT: Please see Ubuntu Server: Apache2 seems to attach .php to URI as I discovered why it does not work but need help so the issue does not occur anymore. ANSWER: The issue is the default Apache configuration on Ubuntu: Options Indexes FollowSymLinks MultiViews MultiViews is changing request_uri from myResource to myResource.php. Solutions: disable MultiViews in .htaccess: Options -MultiViews remove MultiViews from default config rename the file as example to myResourceClass I chose last option because that should work regardless of configuration and I only have 3 such files so the change took about 30 secs...

• How to make XAMPP virtual hosts accessible to VM's and other computers on LAN?

  - by martin's

  XAMPP running on Vista 64 Ultimate dev machine (don't think it matters). Machine / Browser configuration Safari, Firefox, Chrome and IE9 on dev machine IE7 and IE8 on separate XP Pro VM's (VMWare on dev machine) IE10 and Chrome on Windows 8 VM (VMware on dev machine) Safari, Firefox and Chrome running on a iMac (same network as dev) Safari, Firefox and Chrome running on a couple of Mac Pro's (same network as dev) IE7, IE8, IE9 running on other PC's on the same network as dev machine Development Configuration Multiple virtual hosts for different projects .local fake TLD for development No firewall restrictions on dev machine for Apache Some sites have .htaccess mapping www to non-www Port 80 is open in the dev machine's firewall Problem XAMPP local home page (http://192.168.1.98/xampp/) can be accessed from everywhere, real or virtual, by IP All .local sites can be accessed from the browsers on the dev machine. All .local sites can be accessed form the browsers in the XP VM's. Some .local sites cannot be accessed from IE10 or Chrome on the W8 VM Sites that cannot be accessed from W8 VM have a minimal .htaccess file No .local sites can be accessed from ANY machine (PC or Mac) on the LAN hosts on dev machine (relevant excerpt) 127.0.0.1 site1.local 127.0.0.1 site2.local 127.0.0.1 site3.local 127.0.0.1 site4.local 127.0.0.1 site5.local 127.0.0.1 site6.local 127.0.0.1 site7.local 127.0.0.1 site8.local 127.0.0.1 site9.local 192.168.1.98 site1.local 192.168.1.98 site2.local 192.168.1.98 site3.local 192.168.1.98 site4.local 192.168.1.98 site5.local 192.168.1.98 site6.local 192.168.1.98 site7.local 192.168.1.98 site8.local 192.168.1.98 site9.local httpd-vhosts.conf on dev machine (relevant excerpt) NameVirtualHost *:80 <VirtualHost *:80> ServerName localhost ServerAlias localhost *.localhost.* DocumentRoot D:/xampp/htdocs </VirtualHost> # ======================================== site1.local <VirtualHost *:80> ServerName site1.local ServerAlias site1.local *.site1.local DocumentRoot D:/xampp-sites/site1/public_html ErrorLog D:/xampp-sites/site1/logs/access.log CustomLog D:/xampp-sites/site1/logs/error.log combined <Directory D:/xampp-sites/site1> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory> </VirtualHost> NOTE: The above <VirtualHost *:80> block is repeated for each of the nine virtual hosts in the file, no sense in posting it here. hosts on all VM's and physical machines on the network (relevant excerpt) 127.0.0.1 localhost ::1 localhost 192.168.1.98 site1.local 192.168.1.98 site2.local 192.168.1.98 site3.local 192.168.1.98 site4.local 192.168.1.98 site5.local 192.168.1.98 site6.local 192.168.1.98 site7.local 192.168.1.98 site8.local 192.168.1.98 site9.local None of the VM's have any firewall blocks on http traffic. They can reach any site on the real Internet. The same is true of the real machines on the network. The biggest puzzle perhaps is that the W8 VM actually DOES reach some of the virtual hosts. It does NOT reach site2, site6 and site 9, all of which have this minimal .htaccess file. .htaccess file <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] </IfModule> Adding this file to any of the virtual hosts that do work on the W8 VM will break the site (only for W8 VM, not the XP VM's) and require a cache flush on the W8 VM before it will see the site again after deleting the file. Regardless of whether a .htaccess file exists or not, no machine on the same LAN can access anything other than the XAMPP home page via IP. Even with hosts files on all machines. I can ping any virtual host from any machine on the network and get a response from the correct IP address. I can't see anything in out Netgear router that might prevent one machine from reaching the other. Besides, once the local hosts file resolves to an ip address that's all that goes out onto the local network. I've gone through an extensive number of posts on both SO and as the result of Google searches. I can't say that I have found anything definitive anywhere.

• VFS: file-max limit 1231582 reached

  - by Rick Koshi

  I'm running a Linux 2.6.36 kernel, and I'm seeing some random errors. Things like ls: error while loading shared libraries: libpthread.so.0: cannot open shared object file: Error 23 Yes, my system can't consistently run an 'ls' command. :( I note several errors in my dmesg output: # dmesg | tail [2808967.543203] EXT4-fs (sda3): re-mounted. Opts: (null) [2837776.220605] xv[14450] general protection ip:7f20c20c6ac6 sp:7fff3641b368 error:0 in libpng14.so.14.4.0[7f20c20a9000+29000] [4931344.685302] EXT4-fs (md16): re-mounted.

I'm the only one using it, and it's not visible to anyone outside the local network. # lsof | wc 16046 148253 1882901 # ps -ef | wc 574 6104 44260 I saw some documentation saying: file-max & file-nr: The kernel allocates file handles dynamically, but as yet it doesn't free them again. The value in file-max denotes the maximum number of file- handles that the Linux kernel will allocate. When you get lots of error messages about running out of file handles, you might want to increase this limit. Historically, the three values in file-nr denoted the number of allocated file handles, the number of allocated but unused file handles, and the maximum number of file handles. Linux 2.6 always reports 0 as the number of free file handles -- this is not an error, it just means that the number of allocated file handles exactly matches the number of used file handles. Attempts to allocate more file descriptors than file-max are reported with printk, look for "VFS: file-max limit reached". My first reading of this is that the kernel basically has a built-in file descriptor leak, but I find that very hard to believe. It would imply that any system in active use needs to be rebooted every so often to free up the file descriptors. As I said, I can't believe this would be true, since it's normal to me to have Linux systems stay up for months (even years) at a time. On the other hand, I also can't believe that my nearly-idle system is holding over a million files open. Does anyone have any ideas, either for fixes or further diagnosis? I could, of course, just reboot the system, but I don't want this to be a recurring problem every few weeks. As a stopgap measure, I've quit Firefox, which was accounting for almost 2000 lines of lsof output (!) even though I only had one window open, and now I can run 'ls' again, but I doubt that will fix the problem for long. (edit: Oops, spoke too soon. By the time I finished typing out this question, the symptom was/is back) Thanks in advance for any help. And another update: My system was basically unusable, so I decided I had no option but to reboot. But before I did, I carefully quit one process at a time, checking /proc/sys/fs/file-nr after each termination. I found that, predictably, the number of open files gradually went down as I closed things down. Unfortunately, it wasn't a large effect. Yes, I was able to clear up 5000-10000 open files, but there were still over 1.2 million left. I shut down just about everything. All interactive shells, except for the one ssh I left open to finish closing down, httpd, even nfs service. Basically everything in the process table that wasn't a kernel process, and there were still an appalling number of files apparently left open. After the reboot, I found that /proc/sys/fs/file-nr showed about 2000 files open, which is much more reasonable. Starting up 2 Xvnc sessions as usual, along with the dozen or so monitoring windows I like to keep open, brought the total up to about 4000 files. I can see nothing wrong with that, of course, but I've obviously failed to identify the root cause. I'm still looking for ideas, since I definitely expect it to happen again. And another update, the next day: I watched the system carefully, and discovered that /proc/sys/fs/file-nr showed a growth of about 900 open files per hour. I shut down the system's only NFS client for the night, and the growth stopped. Mind you, it didn't free up the resources, but it did at least stop consuming more. Is this a known bug with NFS? I'll be bringing the NFS client back online today, and I'll narrow it down further. If anyone is familiar with this behavior, feel free to jump in with "Yeah, NFS4 has this problem, go back to NFS3" or something like that.

• Set up linux box for hosting a-z

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP/MySQL: To upgrade PHP and MySQL to the latest versions, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! Add IUS repository to our package manager cd /tmp wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. # list all the packages in the IUS repository; use this to find PHP/MySQL version and libraries you want to install Remove old version of PHP and install newer version from IUS rpm -qa | grep php # to list all of the installed php packages we want to remove yum shell # open an interactive yum shell remove php-common php-mysql php-cli #remove installed PHP components install php53 php53-mysql php53-cli php53-common #add packages you want transaction solve #important!! checks for dependencies transaction run #important!! does the actual installation of packages.

Because of the ONBOOT=yes line in the ifcfg-eth1:1 file, this interface will be brought up when the system boots, or the network starts/restarts. service network restart Shutting down interface eth0: [ OK ] Shutting down interface eth1: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] Bringing up interface eth1: [ OK ] ping 192.168.1.3 64 bytes from 192.168.1.3: icmp_seq=1 ttl=64 time=0.105 ms And this is where I'm at. I will keep editing this as I make progress. Any tips on how to Configure virtual interfaces/ip based virtual hosts for SSL, setting up a CA, or anything else would be appreciated.

• Linux/Apache performance very slow even on local network

  - by klausch

  I have an Ubuntu server machine running Apache and MYSQL. System and version info is as follows: Linux kernel 3.0.0.-12 Apache/2.2.20 MySQL Ver 14.14.Distrib 5.1.58 I am running a few websites on this server, some HTML only, some PHP/MySQL. THe [problem is that response time is very slow, both on static as well as the dynamic sites. Sometimes it takes more than 10 seconds before a response is given, this makes the sites very slow and almost unusable. The problem occurs even when requesting from the local network. I have added the involved subdomains to my /etc/hosts file, and abolve all the problem is not solved by using IP numbers instead of URL's. So there is no DNS lookup issue. I have modified the log format by showing the response times and sometimes a files takes 12 seconds to be served, see the jquery~.js file in the example screenshot. I have no explanation for this extremely long response time, but is is not even the only issue here, some other files takes a long time to be served too, but do not show a long response time in the log file. So probably different tissues are involved here. I cannot find a solution until now, any suggestions??? THanx in advance, Klaas link to screenshot picture from access logfile Some extra configuration info: apache2.conf (comment is removed) LockFile ${APACHE_LOCK_DIR}/accept.lock PidFile ${APACHE_PID_FILE} Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 5 <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_event_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} AccessFileName .htaccess <Files ~ "^\.ht"> Order allow,deny Deny from all Satisfy all </Files> DefaultType text/plain HostnameLookups Off ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn Include mods-enabled/*.load Include mods-enabled/*.conf Include httpd.conf Include ports.conf LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\" %T/%D" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent Include conf.d/ Include sites-enabled/ And the virtual hostfile for one of the slow sites, in fact it is pretty straightforward... <VirtualHost *:80> ServerAdmin [email protected] ServerSignature EMail ServerName toenjoy.drsklaus.nl DocumentRoot /var/www/toenjoy.drsklaus.nl <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/toenjoy.drsklaus.nl/> Options Indexes FollowSymLinks MultiViews AllowOverride AuthConfig AuthType Basic AuthName "To Enjoy" AuthUserFile /etc/.htpasswd Require user petraaa Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

I have runned top and it does not appear to be a CPU issue. I have the impression that the spawning of a apache thread could maybe be the bottleneck but it is just a suggestion. Maybe this gives some extra information! EDIT: The problem seemed to be gone for some time but occurs again! And not only with Apache, also connecting using SSH takes a tremendous time, sometimes it takes up to 15 seconds before the keyphrase is asked for. Also scp works very slowly. The behavious is really unpredoctable and makes the server very hard to use. Any ideas...?

• Inconsistent responses from ISAPI DLL in mod_isapi.

  - by William Leader

  I have a ISAPI dll which I created with Delphi 2009, and I have been able to test that it functions as designed when I run it inside of IIS 5.1. However when I attempt to host the web service from within Apache on Windows XP using mod_isapi, I do not get consistent results. The ISAPI dll implements a very simple SOAP service with two methods. One method is a simple echo service that sends back the string sent to it. The second method is used to send a file to the server using a TSoapAttachement (Mutipart MIME). The interface can be descibes as follows IPdiSvc2 = interface(IInvokable) ['{532DCDD7-D66B-4D2C-924E-2F389D3E0A74}'] function Echo(data:string): string; stdcall; function SendFile(request:TFileDescription; attachment: TSOAPAttachment): TSendFileResponse; stdcall; end; What is interesting is if I only call the echo function Apache handles this without error every time. The webservice only returns an error after calling send File, but not every time. There are three outcomes to calling send file that I have observed: A normal result without an error (HTTP 200 OK). A Soap encoded exception with the message: 'Required white space was missing. Line: 11 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML.' (HTTP 500 Internal Error). This also generates a message in the Apache error.log 'Premature end of script headers: MYISAPI.dll' A Soap encoded exception with the message: 'Access violation at address 01A53D57 in module MYISAPI.dll. Read of address 00000000.' (HTTP 200 OK). What I find interesting is that the second third outcomes still occur if I call echo after calling send file. Calling SendFile, SendFile, SendFile, SendFile results in outcomes 1, 2, 3, 1. Calling Echo, SendFile, SendFile, SendFile results in outcomes 1, 1, 2, 3. Calling SendFile, Echo, Echo, SendFile results in outcomes 1, 2, 3, 1. The pattern I am seing is that after a Successful SendFile, the next to requests result in outcomes 2 and 3 regardless of what those two requests are. My guess is that because Apache uses multiple threads to handle multiple requests that each request is getting handled in a slightly different way, and that the DLL may not have been initialized in the same way for each worker thread. I do not think the problem exists in my code as when I attach the debugger to httpd.exe it does recognize the exceptions but it says the exceptions are in non-delphi code meaning that they are happening before the code inside my DLL has a chance to execute. I suspect it may have something to do with the way I have apache configured. My Apache configuration is the defaults created by the 2.2.15 installer for windows with the following addition: <IfModule isapi_module> AddHandler isapi-handler .dll ISAPILogNotSupported on ISAPIFakeAsync on ISAPIAppendLogToErrors on </IfModule> <IfModule alias_module> ScriptAlias /myisapi/ "C:/path/to/myisapi/" </IfModule> <Directory "C:/path/to/myisapi/"> AllowOverride None Options ExecCGI Order allow,deny Allow from all </Directory>

• How to properly deny Railo directory access through Apache

  - by Sn3akyP3t3

  I've been battle tested on this and failed to achieve my goal which is to deny all access to all directories except the Public directory and only allow access to all all other directories with specific IP addresses. To get Railo+Apache+Tomcat installed I pretty much followed this script: https://github.com/talltroym/Railo-Ubuntu-Installer-Script then verified settings with this tutorial: http://blog.nictunney.com/2012/03/railo-tomcat-and-apache-on-amazon-ec2.html From the installation script these mods are enabled: sudo a2enmod ssl sudo a2enmod proxy sudo a2enmod proxy_http sudo a2enmod rewrite sudo a2ensite default-ssl Outside of the script I copied the sites-available to sites-enabled then reloaded Apache. I have a directory created for Railo cmfl located at /var/www/Railo/ Navigating the browser to http ://Server_IP_Address/Railo forces ssl and relocates to https ://Server_IP_Address/Railo which shows off index.cfm. Not providing index.cfm and omitting https indicates that the DirectoryIndex directive and RewriteCond of Apache appears to be working for the sites-enabled VirtualHost. The problem I'm encountering is that I cannot seem to deny access to all directories except Public. My directory structure is rather simple and looks like this: Railo error Public NotPublic Sandbox These are my sites-enabled configurations: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www #Default Deny All to prevent walking backwards in file system Alias /Railo/ "/var/www/Railo/" <Directory ~ ".*/Railo/(?!Public).*"> Order Deny,Allow Deny from All </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation.

The Location directive seems to be working correctly for blocking out Railo admin site access.

• How do I use connect to DB2 with DBI and mod_perl?

  - by Matthew

  I'm having issues with getting DBI's IBM DB2 driver to work with mod_perl. My test script is: #!/usr/bin/perl use strict; use CGI; use Data::Dumper; use DBI; { my $q; my $dsn; my $username; my $password; my $sth; my $dbc; my $row; $q = CGI->new; print $q->header; print $q->start_html(); $dsn = "DBI:DB2:SAMPLE"; $username = "username"; $password = "password"; print "<pre>".$q->escapeHTML(Dumper(\%ENV))."</pre>"; $dbc = DBI->connect($dsn, $username, $password); $sth = $dbc->prepare("SELECT * FROM SOME_TABLE WHERE FIELD='SOMETHING'"); $sth->execute(); $row = $sth->fetchrow_hashref(); print "<pre>".$q->escapeHTML(Dumper($row))."</pre>"; print $q->end_html; } This script works as CGI but not under mod_perl. I get this error in apache's error log: DBD::DB2::dr connect warning: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /usr/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 190. DBI connect('SAMPLE','username',...) failed: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /data/www/perl/test.pl line 15 First of all, why is it using ODBC? The native DB2 driver is installed (hence it works as CGI). Running Apache 2.2.3, mod_perl 2.0.4 under RHEL5. This guy had the same problem as me: http://www.mail-archive.com/[email protected]/msg22909.html But I have no idea how he fixed it. What does mod_php4 have to do with mod_perl? Any help would be greatly appreciated, I'm having no luck with google. Update: As james2vegas pointed out, the problem has something to do with PHP: I disable PHP all together I get the a different error: Total Environment allocation failure! Did you set up your DB2 client environment? I believe this error is to do with environment variables not being set up correctly, namely DB2INSTANCE. However, I'm not able to turn off PHP to resolve this problem (I need it for some legacy applications). So I now have 2 questions: How can I fix the original issue without disabling PHP all together? How can I fix the environment issue? I've set DB2INSTANCE, DB2_PATH and SQLLIB variables correctly using SetEnv and PerlSetEnv in httpd.conf, but with no luck. Note: I've edited the code to determine if the problem was to do with Global Variable Persistence.

• Problem with URL encoded parameters in URL view helper

  - by Richard Knop

  So my problem is kinda weird, it only occurs when I test the application offline (on my PC with WampServer), the same code works 100% correctly online. Here is how I use the helper (just example): <a href="<?php echo $this->url(array('module' => 'admin', 'controller' => 'index', 'action' => 'approve-photo', 'id' => $this->escape($a->id), 'ret' => urlencode('admin/index/photos')), null, true); ?>" class="blue">approve</a> Online, this link works great, it goes to the action which looks similar to this: public function approvePhotoAction() { $request = $this->getRequest(); $photos = $this->_getTable('Photos'); $dbTrans = false; try { $db = $this->_getDb(); $dbTrans = $db->beginTransaction(); $photos->edit($request->getParam('id'), array('status' => 'approved')); $db->commit(); } catch (Exception $e) { if (true === $dbTrans) { $db->rollBack(); } } $this->_redirect(urldecode($request->getParam('ret'))); } So online, it approves the photo and redirects back to the URL that is encoded as "ret" param in the URL ("admin/index/photos"). But offline with WampServer I click on the link and get 404 error like this: Not Found The requested URL /public/admin/index/approve-photo/id/1/ret/admin/index/photos was not found on this server. What the hell? I'm using the latest version of WampServer (WampServer 2.0i [11/07/09]). Everything else works. Here is my .htaccess file, just in case: RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ /index.php [NC,L] # Turn off magic quotes #php_flag magic_quotes_gpc off I'm using virtual hosts to test ZF projects on my local PC. Here is how I add virtual hosts. httpd.conf: NameVirtualHost *:80 <VirtualHost *:80> ServerName myproject DocumentRoot "C:\wamp\www\myproject" </VirtualHost> the hosts file: 127.0.0.1 myproject Any help would be appreciated because this makes testing and debugging projects on my localhost a nightmare and almost impossible task. I have to upload everything online to check if it works :( UPDATE: Source code of the _redirect helper (built in ZF helper): /** * Set redirect in response object * * @return void */ protected function _redirect($url) { if ($this->getUseAbsoluteUri() && !preg_match('#^(https?|ftp)://#', $url)) { $host = (isset($_SERVER['HTTP_HOST'])?$_SERVER['HTTP_HOST']:''); $proto = (isset($_SERVER['HTTPS'])&&$_SERVER['HTTPS']!=="off") ? 'https' : 'http'; $port = (isset($_SERVER['SERVER_PORT'])?$_SERVER['SERVER_PORT']:80); $uri = $proto . '://' . $host; if ((('http' == $proto) && (80 != $port)) || (('https' == $proto) && (443 != $port))) { $uri .= ':' . $port; } $url = $uri . '/' . ltrim($url, '/'); } $this->_redirectUrl = $url; $this->getResponse()->setRedirect($url, $this->getCode()); } UPDATE 2: Output of the helper offline: /admin/index/approve-photo/id/1/ret/admin%252Findex%252Fphotos And online (the same): /admin/index/approve-photo/id/1/ret/admin%252Findex%252Fphotos UPDATE 3: OK. The problem was actually with the virtual host configuration. The document root was set to C:\wamp\www\myproject instead of C:\wamp\www\myproject\public. And I was using this htaccess to redirect to the public folder: RewriteEngine On php_value upload_max_filesize 15M php_value post_max_size 15M php_value max_execution_time 200 php_value max_input_time 200 # Exclude some directories from URI rewriting #RewriteRule ^(dir1|dir2|dir3) - [L] RewriteRule ^\.htaccess$ - [F] RewriteCond %{REQUEST_URI} ="" RewriteRule ^.*$ /public/index.php [NC,L] RewriteCond %{REQUEST_URI} !^/public/.*$ RewriteRule ^(.*)$ /public/$1 RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^.*$ - [NC,L] RewriteRule ^public/.*$ /public/index.php [NC,L] Damn it I don't know why I forgot about this, I thought the virtual host was configured correctly to the public folder, I was 100% sure about that, I also double checked it and saw no problem (wtf? am I blind?).

• Why do we need different CPU architecture for server & mini/mainframe & mixed-core?

  - by claws

  Hello, I was just wondering what other CPU architectures are available other than INTEL & AMD. So, found List of CPU architectures on Wikipedia. It categorizes notable CPU architectures into following categories. Embedded CPU architectures Microcomputer CPU architectures Workstation/Server CPU architectures Mini/Mainframe CPU architectures Mixed core CPU architectures I was analyzing the purposes and have few doubts. I taking Microcomputer CPU (PC) architecture as reference and comparing others. Embedded CPU architecture: They are a completely new world. Embedded systems are small & do very specific task mostly real time & low power consuming so we do not need so many & such wide registers available in a microcomputer CPU (typical PC). In other words we do need a new small & tiny architecture. Hence new architecture & new instruction RISC. The above point also clarifies why do we need a separate operating system (RTOS). Workstation/Server CPU architectures I don't know what is a workstation. Someone clarify regarding the workstation. As of the server. It is dedicated to run a specific software (server software like httpd, mysql etc.). Even if other processes run we need to give server process priority therefore there is a need for new scheduling scheme and thus we need operating system different than general purpose one. If you have any more points for the need of server OS please mention. But I don't get why do we need a new CPU Architecture. Why cant Microcomputer CPU architecture do the job. Can someone please clarify? Mini/Mainframe CPU architectures Again I don't know what are these & what miniframes or mainframes used for? I just know they are very big and occupy complete floor. But I never read about some real world problems they are trying to solve. If any one working on one of these. Share your knowledge. Can some one clarify its purpose & why is it that microcomputer CPU archicture not suitable for it? Is there a new kind of operating system for this too? Why? Mixed core CPU architectures Never heard of these. If possible please keep your answer in this format: XYZ CPU architectures Purpose of XYZ Need for a new architecture. why can't current microcomputer CPU architecture work? They go upto 3GHZ & have upto 8 cores. Need for a new Operating System Why do we need a new kind of operating system for this kind of archictures?

• Did I find a bug in PHP's `crypt()`?

  - by Nathan Long

  I think I may have found a bug in PHP's crypt() function under Windows. However: I recognize that it's probably my fault. PHP is used by millions and worked on by thousands; my code is used by tens and worked on by me. (This argument is best explained on Coding Horror.) So I'm asking for help: show me my fault. I've been trying to find it for a few days now, with no luck. The setup I'm using a Windows server installation with Apache 2.2.14 (Win32) and PHP 5.3.2. My development box runs Windows XP Professional; the 'production' server (this is an intranet setup) runs Windows Storage Server 2003. The problem happens on both. I don't see anything in php.ini related to crypt(), but will happily answer questions about my config. The problem Several scripts in my PHP app occasionally hang: the page sits there on 'waiting for localhost' and never finishes. Each of these scripts uses crypt to hash a user's password before storing it in the database, or, in the case of the login page, to hash the entered password before comparing it to the version stored in the database. Since the login page is the simplest, I focused on it for testing. I repeatedly logged in, and found that it would hang maybe 4 out of 10 times. As an experiment, I changed the login page to use the plain text password and changed my password in the database to its plain text version. The page stopped hanging. I saw that PHP's latest version lists this bugfix: Fixed bug #51059 (crypt crashes when invalid salt are [sic] given). So I created a very simple test script, as follows, using the same salt given in an official example: $foo = crypt('rasmuslerdorf','r1'); echo $foo; This page, too, will hang, if I reload it like crazy. I only see it hanging in Chrome, but regardless of browser, the effect on Apache is the same. Effect on Apache When these pages hang, Apache's server-status page (which I explained here, regarding a different problem) increments the number of requests being processed and decrements the number of idle workers. The requests being processed almost all have a status of 'Sending Reply,' though sometimes for a moment they will show either 'Reading request' or 'keepalive (read).' Eventually, Apache may crash. When it does, the Windows crash report looks like this: szAppName: httpd.exe szAppVer: 2.2.14.0 szModName: php5ts.dll szModVer: 5.3.1.0 // OK, this report was before I upgraded to PHP 5.3.2, // but that didn't fix it offset: 00a2615 Is it my fault? I'm tempted to file a bug report to PHP on this. The argument against it is, as stated above, that bugs are nearly always my fault. However, my argument in favor of 'it's PHP's fault' is: I'm using Windows, whereas most servers use Linux (I don't get to choose this), so the chances are greater that I've found an edge case There was recently a bug with crypt(), so maybe it still has issues I have made the simplest test case I can, and I still have the problem Can anyone duplicate this? Can you suggest where I've gone wrong? Should I file the bug after all? Thanks in advance for any help you may give.

• AIX Checklist for stable obiee deployment

  - by user554629

  Common AIX configuration issues     ( last updated 27 Aug 2012 ) OBIEE is a complicated system with many moving parts and connection points.The purpose of this article is to provide a checklist to discuss OBIEE deployment with your systems administrators. The information in this article is time sensitive, and updated as I discover new  issues or details. What makes OBIEE different? When Tech Support suggests AIX component upgrades to a stable, locked-down production AIX environment, it is common to get "push back".  "Why is this necessary?  We aren't we seeing issues with other software?"It's a fair question that I have often struggled to answer; here are the talking points: OBIEE is memory intensive.  It is the entire purpose of the software to trade memory for repetitive, more expensive database requests across a network. OBIEE is implemented in C++ and is very dependent on the C++ runtime to behave correctly. OBIEE is aggressively thread efficient;  if atomic operations on a particular architecture do not work correctly, the software crashes. OBIEE dynamically loads third-party database client libraries directly into the nqsserver process.  If the library is not thread-safe, or corrupts process memory the OBIEE crash happens in an unrelated part of the code.  These are extremely difficult bugs to find. OBIEE software uses 99% common source across multiple platforms:  Windows, Linux, AIX, Solaris and HPUX.  If a crash happens on only one platform, we begin to suspect other factors.  load intensity, system differences, configuration choices, hardware failures.  It is rare to have a single product require so many diverse technical skills.   My role in support is to understand system configurations, performance issues, and crashes.   An analyst trained in Business Analytics can't be expected to know AIX internals in the depth required to make configuration choices.  Here are some guidelines. AIX C++ Runtime must be at  version 11.1.0.4$ lslpp -L | grep xlC.aixobiee software will crash if xlC.aix.rte is downlevel;  this is not a "try it" suggestion.Nov 2011 11.1.0.4 version  is appropriate for all AIX versions ( 5, 6, 7 )Download from here:https://www-304.ibm.com/support/docview.wss?uid=swg24031426 No reboot is necessary to install, it can even be installed while applications are using the current version.Restart the apps, and they will pick up the latest version. AIX 5.3 Technology Level 12 is required when running on Power5,6,7 processorsAIX 6.1 was introduced with the newer Power chips, and we have seen no issues with 6.1 or 7.1 versions.Customers with an unstable deployment, dozens of unexplained crashes, became stable after the upgrade.If your AIX system is 5.3, the minimum TL level should be at or higher than this:$ oslevel -s  5300-12-03-1107IBM typically supports only the two latest versions of AIX ( 6.1 and 7.1, for example).  AIX 5.3 is still supported and popular running in an LPAR. obiee userid limits$ ulimit -Ha  ( hard limits )$ ulimit -a   ( default limits )core file size (blocks)     unlimiteddata seg size (kbytes)      unlimitedfile size (blocks)          unlimitedmax memory size (kbytes)    unlimitedopen files                  10240 cpu time (seconds)          unlimitedvirtual memory (kbytes)     unlimitedIt is best to establish the values in /etc/security/limitsroot user is needed to observe and modify this file.If you modify a limit, you will need to relog in to change it again.  For example,$ ulimit -c 0$ ulimit -c 2097151cannot modify limit: Operation not permitted$ ulimit -c unlimited$ ulimit -c0There are only two meaningful values for ulimit -c ; zero or unlimited.Anything else is likely to produce a truncated core file that cannot be analyzed. Deploy 32-bit or 64-bit ?Early versions of OBIEE offered 32-bit or 64-bit choice to AIX customers.The 32-bit choice was needed if a database vendor did not supply a 64-bit client library.That's no longer an issue and beginning with OBIEE 11, 32-bit code is no longer shipped.A common error that leads to "out of memory" conditions to to accept the 32-bit memory configuration choices on 64-bit deployments.  The significant configuration choices are: Maximum process data (heap) size is in an AIX environment variableLDR_CNTRL=IGNOREUNLOAD@LOADPUBLIC@PREREAD_SHLIB@MAXDATA=0x... Two thread stack sizes are made in obiee NQSConfig.INI[ SERVER ]SERVER_THREAD_STACK_SIZE = 0;DB_GATEWAY_THREAD_STACK_SIZE = 0; Sort memory in NQSConfig.INI[ GENERAL ]SORT_MEMORY_SIZE = 4 MB ;SORT_BUFFER_INCREMENT_SIZE = 256 KB ; Choosing a value for MAXDATA:0x080000000  2GB Default maximum 32-bit heap size ( 8 with 7 zeros )0x100000000  4GB 64-bit breaking even with 32-bit ( 1 with 8 zeros )0x200000000  8GB 64-bit double 32-bit max0x400000000 16GB 64-bit safetyUsing 2GB heap size for a 64-bit process will almost certainly lead to an out-of-memory situation.Registers are twice as big ... consume twice as much memory in the heap.Upgrading to a 4GB heap for a 64-bit process is just "breaking even" with 32-bit.A 32-bit process is constrained by the 32-bit virtual addressing limits.  Heap memory is used for dynamic requirements of obiee software, thread stacks for each of the configured threads, and sometimes for shared libraries. 64-bit processes are not constrained in this way;  extra heap space can be configured for safety against a query that might create a sudden requirement for excessive storage.  If the storage is not available, this query might crash the whole server and disrupt existing users.There is no performance penalty on AIX for configuring more memory than required;  extra memory can be configured for safety.  If there are no other considerations, start with 8GB.Choosing a value for Thread Stack size:zero is the value documented to select an appropriate default for thread stack size.  My preference is to change this to an absolute value, even if you intend to use the documented default;  it provides better documentation and removes the "surprise" factor.There are two thread types that can be configured. GATEWAY is used by a thread pool to call a database client library to establish a DB connection.The default size is 256KB;  many customers raise this to 512KB ( no performance penalty for over-configuring ). This value must be set to 1 MB if Teradata connections are used. SERVER threads are used to run queries.  OBIEE uses recursive algorithms during the analysis of query structures which can consume significant thread stack storage.  It's difficult to provide guidance on a value that depends on data and complexity.  The general notion is to provide more space than you think you need,  "double down" and increase the value if you run out, otherwise inspect the query to understand why it is too complex for the thread stack.  There are protections built into the software to abort a single user query that is too complex, but the algorithms don't cover all situations.256 KB  The default 32-bit stack size.  Many customers increased this to 512KB on 32-bit.  A 64-bit server is very likely to crash with this value;  the stack contains mostly register values, which are twice as big.512 KB  The documented 64-bit default.  Some early releases of obiee didn't set this correctly, resulting in 256KB stacks.1 MB  The recommended 64-bit setting.  If your system only ever uses 512KB of stack space, there is no performance penalty for using 1MB stack size.2 MB  Many large customers use this value for safety.  No performance penalty.nqscheduler does not use the NQSConfig.INI file to set thread stack size.If this process crashes because the thread stack is too small, use this to set 2MB:export OBI_BACKGROUND_STACK_SIZE=2048 Shared libraries are not (shared) When application libraries are loaded at run-time, AIX makes a decision on whether to load the libraries in a "public" memory segment.  If the filesystem library permissions do not have the "Read-Other" permission bit, AIX loads the library into private process memory with two significant side-effects:* The libraries reduce the heap storage available.      Might be significant in 32-bit processes;  irrelevant in 64-bit processes.* Library code is loaded into multiple real pages for execution;  one copy for each process.Multiple execution images is a significant issue for both 32- and 64-bit processes.The "real memory pages" saved by using public memory segments is a minor concern.  Today's machines typically have plenty of real memory.The real problem with private copies of libraries is that they consume processor cache blocks, which are limited.   The same library instructions executing in different real pages will cause memory delays as the i-cache ( instruction cache 128KB blocks) are refreshed from real memory.   Performance loss because instructions are delayed is something that is difficult to measure without access to low-level cache fault data.   The machine just appears to be running slowly for no observable reason.This is an easy problem to detect, and an easy problem to correct.Detection:  "genld -l" AIX command produces a list of the libraries used by each process and the AIX memory address where they are loaded.32-bit public segment is 13 ( "dxxxxxxx" ).   private segments are 2-a.64-bit public segment is 9 ( "9xxxxxxxxxxxxxxx") ; private segment is 8.genld -l | grep -v ' d| 9' | sort +2provides a list of privately loaded libraries. Repair: chmod o+r <libname>AIX shared libraries will have a suffix of ".so" or ".a".Another technique is to change all libraries in a selected directory to repair those that might not be currently loaded.   The usual directories that need repair are obiee code, httpd code and plugins, database client libraries and java.chmod o+r /shr/dir/*.a /shr/dir/*.so Configure your system for diagnosticsProduction systems shouldn't crash, and yet bad things happen to good software.If obiee software crashes and produces a core, you should configure your system for reliable transfer of the failing conditions to Oracle Tech Support.  Here's what we need to be able to diagnose a core file from your system.* fullcore enabled. chdev -lsys0 -a fullcore=true* core naming enabled. chcore -n on -d* ulimit must not truncate core. see item 3.* pstack.sh is used to capture core documentation.* obidoc is used to capture current AIX configuration.* snapcore  AIX utility captures core and libraries.

Disable Oracle Client Library signal handlingThe Oracle DB Client Library is frequently distributed with the sqlplus development kit.By default, the library enables a signal handler, which will document a call stack if the application crashes.   The signal handler is not needed, and definitely disruptive to obiee diagnostics.   It needs to be disabled.   sqlnet.ora is typically located at:   $ORACLE_HOME/network/admin/sqlnet.oraAdd this line at the top of the file:   DIAG_SIGHANDLER_ENABLED=FALSE Disable async query in the RPD connection pool.This might be an obiee 10.1.3.4 issue only ( still checking  )."async query" must be disabled in the connection pools.It was designed to enable query cancellation to a database, and turned out to have too many edge conditions in normal communication that produced random corruption of data and crashes.  Please ensure it is turned off in the RPD. Check AIX error report (errpt).Errors external to obiee applications can trigger crashes.  $ /bin/errpt -aHardware errors ( firmware, adapters, disks ) should be reported to IBM support.All application core files are recorded by AIX;  the most recent ones are listed first.

• Confluence or apache on win server 2008 cant find scripts and images :(

  - by Ishak

  I am a newbie to both Tomcat and Apache. I have set the virtual hosts as described in Here. And JIRA works fine when i browse the URL jira.agmlab.com. However when i try to access Confluence(3.4.5) with confluence.agmlab.com the pages come in plain html, i can login and browse pages but there is no css or js so that my confluence pages look very ugly. what can possibly cause this and how to fix this? here is my virtual hosts definitions : # # Virtual Hosts # # If you want to maintain multiple domains/hostnames on your # machine you can setup VirtualHost containers for them. Most configurations # use only name-based virtual hosts so the server doesn't need to worry about # IP addresses. This is indicated by the asterisks in the directives below. # # Please see the documentation at # <URL:http://httpd.apache.org/docs/2.2/vhosts/> # for further details before you try to setup virtual hosts. # # You may use the command line option '-S' to verify your virtual host # configuration. # # Use name-based virtual hosting. # NameVirtualHost * # # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for all requests that do not # match a ServerName or ServerAlias in any <VirtualHost> block. # <VirtualHost *> ServerName confluence.agmlab.com ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8081/confluence/ ProxyPassReverse / http://localhost:8081/confluence/ # ProxyHTMLURLMap /confluence/ / <Location /> Order allow,deny Allow from all </Location> </VirtualHost> <VirtualHost *> ServerName jira.agmlab.com ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> and i added 127.0.0.1 jira.agmlab.com 127.0.0.1 confluence.agmlab.com to my hosts file (i am using Win Server 2008 OS). here is part of the error log from Apache access.log file : 127.0.0.1 -

Can it be something related with the permissions defined in Win Server 2008 ? maybe there is not enough rights (such as read execute ) in some users, directories ??

• Injection of banners in my webbrowsers possible malware

  - by Skadlig

  Recently I have started to suspect that I have some kind of virus on my computer. There are 3 symptoms: Banners are being displayed on pages that doesn't use commercials, for instance when viewing screen-shots on Steam. It is only displayed after the rest of the page has been loaded and seems to be injected into it. The whole page is replaced with a commercial with the option to skip the commercial. The page is replaced with a search window claiming that the page could not be found. I have tried to scan my computer with Antivir and Adaware but only found a couple of tracking cookies. I have run HijackThis but since this isn't really my area I haven't been able to discern what shouldn't be there except the line about zonealarm since I have uninstalled it. Is there anyone out there who is able to see if there is anything suspicious in the log-file at the end or has suggestions regarding programs that might be better to find the virus than Antivir and Adaware? Here is the whole (long) log: Logfile of Trend Micro HijackThis v2.0.2 Scan saved at 21:44:07, on 2010-04-15 Platform: Unknown Windows (WinNT 6.01.3504) MSIE: Internet Explorer v8.00 (8.00.7600.16385) Boot mode: Normal Running processes: C:\Windows\SysWOW64\HsMgr.exe C:\Program Files (x86)\Personal\bin\Personal.exe F:\Program Files (x86)\Apache Software Foundation\Apache2.2\bin\ApacheMonitor.exe C:\Program Files (x86)\Avira\AntiVir Desktop\avgnt.exe F:\Program Files (x86)\PowerISO\PWRISOVM.EXE C:\Program Files (x86)\Java\jre6\bin\jusched.exe C:\Program Files\ASUS Xonar DX Audio\Customapp\ASUSAUDIOCENTER.EXE F:\Program Files (x86)\Voddler\service\VNetManager.exe C:\Program Files (x86)\Emotum\Mobile Broadband\Mobile.exe F:\Program Files\Logitech\SetPoint\x86\SetPoint32.exe C:\Program Files (x86)\Lavasoft\Ad-Aware\AAWTray.exe F:\Program Files (x86)\Mozilla Firefox\firefox.exe F:\Program Files (x86)\Trend Micro\HijackThis\HijackThis.exe R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://go.microsoft.com/fwlink/?LinkId=54896 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page = C:\Windows\SysWOW64\blank.htm R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = F2 - REG:system.ini: UserInit=userinit.exe O2 - BHO: AcroIEHelperStub - {18DF081C-E8AD-4283-A596-FA578C2EBDC3} - C:\Program Files (x86)\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelperShim.dll O2 - BHO: gwprimawega - {83bb5261-81ec-25ae-4adf-e88936738525} - C:\Windows\SysWow64\aZfJupUw.dll O2 - BHO: ZoneAlarm Toolbar Registrar - {8A4A36C2-0535-4D2C-BD3D-496CB7EED6E3} - C:\Program Files\CheckPoint\ZAForceField\WOW64\TrustChecker\bin\TrustCheckerIEPlugin.dll (file missing) O2 - BHO: Windows Live inloggningshjälpen - {9030D464-4C02-4ABF-8ECC-5164760863C6} - C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live\WindowsLiveLogin.dll O2 - BHO: Java(tm) Plug-In 2 SSV Helper - {DBC80044-A445-435b-BC74-9C25C1C588A9} - C:\Program Files (x86)\Java\jre6\bin\jp2ssv.dll O3 - Toolbar: ZoneAlarm Toolbar - {EE2AC4E5-B0B0-4EC6-88A9-BCA1A32AB107} - C:\Program Files\CheckPoint\ZAForceField\WOW64\TrustChecker\bin\TrustCheckerIEPlugin.dll (file missing) O4 - HKLM..\Run: [avgnt] "C:\Program Files (x86)\Avira\AntiVir Desktop\avgnt.exe" /min O4 - HKLM..\Run: [PWRISOVM.EXE] f:\Program Files (x86)\PowerISO\PWRISOVM.EXE O4 - HKLM..\Run: [SunJavaUpdateSched] "C:\Program Files (x86)\Java\jre6\bin\jusched.exe" O4 - HKLM..\Run: [QuickTime Task] "F:\Program Files (x86)\QuickTime\QTTask.exe" -atboottime O4 - HKLM..\Run: [Adobe Reader Speed Launcher] "C:\Program Files (x86)\Adobe\Reader 9.0\Reader\Reader_sl.exe" O4 - HKLM..\Run: [VoddlerNet Manager] f:\Program Files (x86)\Voddler\service\VNetManager.exe O4 - HKCU..\Run: [Steam] "f:\program files (x86)\steam\steam.exe" -silent O4 - HKCU..\Run: [msnmsgr] "C:\Program Files (x86)\Windows Live\Messenger\msnmsgr.exe" /background O4 - Global Startup: BankID Security Application.lnk = C:\Program Files (x86)\Personal\bin\Personal.exe O4 - Global Startup: Logitech SetPoint.lnk = ?

  I have an iptables firewall running on a Fedora Linux server that is basically being used as a firewall router and OpenVPN server. That's it. We have been using the same iptables firewall code for YEARS. I did make some changes on 21 December to re-route a mySQL port, but given what has happened I've completely backed those changes out. Sometime after those changes were made and backed out passive FTP, served from a vsftpd process, stopped working. We use a passive ftp client to FLING (that's the name of the ftp client running under Windows! :-) ) images from our remote telescopes to our server. I believe it is something in the firewall code because I can drop the firewall and the FTP file transfer (and connecting to the ftp site with Internet Explorer to see the file list) works. When I raise the iptables firewall, it stops working. Again, this is code that we'd been using for years. However, I felt that maybe there was something I missed, so we had a .bak file from 2009 that I used. Same behavior, passive ftp does not work. So, I went and rebuilt the firewall code line by line to see what line was causing the problem. Everything worked until I put the line -A FORWARD -j DROP in very near the end. Of course, if I am correct, this is the line that basically "turns on" the firewall, saying drop everything except for the exceptions I've made above. However, this line has been in the iptables code probably since 2003. So, I'm at the end of my rope, and I still can't figure out why this has stopped working. I guess I need an expert on iptables configuration. Here is the iptables code (from iptables-save) with comments. # Generated by iptables-save v1.3.8 on Thu Jan 5 18:36:25 2012 *nat # One of the things that I remain ignorant about is what these following three lines # do in both the nat tables (which we're not using on this machine) and the following # filter table.

As you can see, I've tried to get it working (again) and tried to do some research on the issue, but have come up...short. Any answers would be appreciated by both me and various variable star astronomers around the world! THANKS! -Richard "Doc" Kinne, American Assoc. of Variable Star Observers, [email protected]

• Filtering bad requests from Apache -> logger -> rsyslog to syslog-ng on a remote logging server possible?

  - by zeyus

  EDIT: Thanks for the help Here is a quick idea of the setup: webserver X In apache httpd.conf: LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vcombined CustomLog "|/usr/bin/logger -p local6.info -t access " vcombined In rsyslog.conf: *.* @logserver Logserver syslog-ng.conf: ... parser p_apache {csv-parser(columns( "APACHE.VIRTUAL_HOST", "APACHE.CLIENT_IP", "APACHE.IDENT_NAME", "APACHE.USER_NAME", "APACHE.TIMESTAMP", "APACHE.REQUEST_URL", "APACHE.REQUEST_STATUS", "APACHE.CONTENT_LENGTH", "APACHE.REFERER", "APACHE.USER_AGENT", "APACHE.PROCESS_TIME", "APACHE.SERVER_NAME") # flags: # escape-none,escape-backslash,escape-double-char, # strip-whitespace flags(escape-double-char,strip-whitespace) delimiters(" ") quote-pairs('""[]') );}; ... source s_net { udp(ip(0.0.0.0) port(514) so_rcvbuf(1048576)); }; destination hosts_acc { file("/var/log/hosts/$HOST/${APACHE.VIRTUAL_HOST}_acc.log"); }; filter f_apacheacc { facility(local6); }; log { source(s_net); parser(p_apache); filter(f_apacheacc); destination(hosts_acc); }; ...

• Slow NFS and GFS2 performance

  - by Tiago

  Recently I've designed and configured a 4 node cluster for a webapp that does lots of file handling. The cluster have been broken down into 2 main roles, webserver and storage. Each role is replicated to a second server using drbd in active/passive mode. The webserver does a NFS mount of the data directory of the storage server and the latter also has a webserver running to serve files to browser clients. In the storage servers I've created a GFS2 FS to hold the data which is wired to drbd. I've chose GFS2 mainly because the announced performance and also because the volume size which has to be pretty high. Since we entered production I've been facing two problems that I think are deeply connected. First of all, the NFS mount on the webservers keeps hanging for a minute or so and then resumes normal operations. By analyzing the logs I've found out that NFS stops answering for a while and outputs the following log lines: Oct 15 18:15:42 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:44 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:46 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:48 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:48 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:51 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:52 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:52 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:55 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:55 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:58 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK In this case, the hang lasted for 16 seconds but sometimes it takes 1 or 2 minutes to resume normal operations. My first guess was this was happening due to heavy load of the NFS mount and that by increasing RPCNFSDCOUNT to a higher value, this would become stable. I've increased it several times and apparently, after a while, the logs started appearing less times. The value is now on 32. After further investigating the issue, I've came across a different hang, despite the NFS messages still appear in the logs. Sometimes, the GFS2 FS simply hangs which causes both the NFS and the storage webserver to serve files. Both stay hang for a while and then they resume normal operations. This hangs leaves no trace on client side (also leaves no NFS ... not responding messages) and, on the storage side, the log system appears to be empty, even though the rsyslogd is running. The nodes connect themselves through a 10Gbps non-dedicated connection but I don't think this is an issue because the GFS2 hang is confirmed but connecting directly to the active storage server. I've been trying to solve this for a while now and I've tried different NFS configuration options, before I've found out the GFS2 FS is also hanging. The NFS mount is exported as such: /srv/data/ <ip_address>(rw,async,no_root_squash,no_all_squash,fsid=25) And the NFS client mounts with: mount -o "async,hard,intr,wsize=8192,rsize=8192" active.storage.vlan:/srv/data /srv/data After some tests, these were the configurations that yielded more performance to the cluster. I am desperate to find a solution for this as the cluster is already in production mode and I need to fix this so that this hangs won't happen in the future and I don't really know for sure what and how I should be benchmarking. What I can tell is that this is happening due to heavy loads as I have tested the cluster earlier and this problems weren't happening at all. Please tell me if you need me to provide configuration details of the cluster, and which do you want me to post. As last resort I can migrate the files to a different FS but I need some solid pointers on whether this will solve this problems as the volume size is extremely large at this point. The servers are being hosted by a third-party enterprise and I don't have physical access to them. Best regards. EDIT 1: The servers are physical servers and their specs are: Webservers: Intel Bi Xeon E5606 2x4 2.13GHz 24GB DDR3 Intel SSD 320 2 x 120GB Raid 1 Storage: Intel i5 3550 3.3GHz 16GB DDR3 12 x 2TB SATA Initially there was a VRack setup between the servers but we've upgraded one of the storage servers to have more RAM and it wasn't inside the VRack. They connect through a shared 10Gbps connection between them. Please note that it is the same connection that is used for public access. They use a single IP (using IP Failover) to connect between them and to allow for a graceful failover. NFS is therefore over a public connection and not under any private network (it was before the upgrade, were the problem still existed). The firewall was configured and tested thoroughly but I disabled it for a while to see if the problem still occurred, and it did. From my knowledge the hosting provider isn't blocking or limiting the connection between either the servers and the public domain (at least under a given bandwidth consumption threshold that hasn't been reached yet). Hope this helps figuring out the problem.

I've also ran ping for a long time without any packet loss. MTU size is the normal 1500. As there is no VLan by now, this is the MTU used to communicate between servers. The webservers' network environment is similar. One thing I forgot to mention is that the storage servers handle ~200GB of new files each day through the NFS connection, which is a key point for me to think this is some kind of heavy load problem with either NFS or GFS2. If you need further configuration details please tell me. EDIT 3: Earlier today we had a major filesystem crash on the storage server. I couldn't get the details of the crash right away because the server stop responding. After the reboot, I noticed the filesystem was extremely slow, and I was not being able to serve a single file through either NFS or httpd, perhaps due to cache warming or so. Nevertheless, I've been monitoring the server closely and the following error came up in dmesg. The source of the problem is clearly GFS, which is waiting for a lock and ends up starving after a while. INFO: task nfsd:3029 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. nfsd D 0000000000000000 0 3029 2 0x00000080 ffff8803814f79e0 0000000000000046 0000000000000000 ffffffff8109213f ffff880434c5e148 ffff880624508d88 ffff8803814f7960 ffffffffa037253f ffff8803815c1098 ffff8803814f7fd8 000000000000fb88 ffff8803815c1098 Call Trace: [<ffffffff8109213f>] ? wake_up_bit+0x2f/0x40 [<ffffffffa037253f>] ? gfs2_holder_wake+0x1f/0x30 [gfs2] [<ffffffff814ff42e>] __mutex_lock_slowpath+0x13e/0x180 [<ffffffff814ff2cb>] mutex_lock+0x2b/0x50 [<ffffffffa0379f21>] gfs2_log_reserve+0x51/0x190 [gfs2] [<ffffffffa0390da2>] gfs2_trans_begin+0x112/0x1d0 [gfs2] [<ffffffffa0369b05>] ? gfs2_dir_check+0x35/0xe0 [gfs2] [<ffffffffa0377943>] gfs2_createi+0x1a3/0xaa0 [gfs2] [<ffffffff8121aab1>] ? avc_has_perm+0x71/0x90 [<ffffffffa0383d1e>] gfs2_create+0x7e/0x1a0 [gfs2] [<ffffffffa037783f>] ? gfs2_createi+0x9f/0xaa0 [gfs2] [<ffffffff81188cf4>] vfs_create+0xb4/0xe0 [<ffffffffa04217d6>] nfsd_create_v3+0x366/0x4c0 [nfsd] [<ffffffffa0429703>] nfsd3_proc_create+0x123/0x1b0 [nfsd] [<ffffffffa041a43e>] nfsd_dispatch+0xfe/0x240 [nfsd] [<ffffffffa025a5d4>] svc_process_common+0x344/0x640 [sunrpc] [<ffffffff810602a0>] ? default_wake_function+0x0/0x20 [<ffffffffa025ac10>] svc_process+0x110/0x160 [sunrpc] [<ffffffffa041ab62>] nfsd+0xc2/0x160 [nfsd] [<ffffffffa041aaa0>] ? nfsd+0x0/0x160 [nfsd] [<ffffffff81091de6>] kthread+0x96/0xa0 [<ffffffff8100c14a>] child_rip+0xa/0x20 [<ffffffff81091d50>] ? kthread+0x0/0xa0 [<ffffffff8100c140>] ? child_rip+0x0/0x20
