• Help with Windows 7 BSOD with windbg minidump !analyze -v results

  - by Kurt Harless

  Hi gang, Windows 7 X64 Ultimate is BSODing occasionally. I suspect an overheating issue or something related to the use of my GTX-295 card that runs very hot. Here is an !analyze -v listing of the most recent minidump. Any and all help greatly appreciated. Kurt Microsoft (R) Windows Debugger Version 6.12.0002.633 AMD64 Copyright (c) Microsoft Corporation.

• Installing Apache/MySQL/PHP on Mac OS X Snow Leopard without a direct internet connection.

  - by Moshe

  Are there any good sites that explain the process in such a way that it can be done on a Mac without internet? I would put the installers on a USB drive and move them from an internet enabled machine. I found this site, but it's a bit much. I'm not up for compiling things... http://adylitica.com/2009/11/24/installing-amp-apache-mysql-php-on-mac-os-x-10-6-snow-leopard/

• .htaccess working on remote server but does not work on localhost. Getting 404 errors on localhost

  - by Afsheen Khosravian

  MY PROBLEM: When I visit localhost the site does not work. It shows some text from the site but it seems the server can not locate any other files. Here is a snippet of the errors from firebug: "NetworkError: 404 Not Found - localhost/css/popup.css" "NetworkError: 404 Not Found - localhost/css/style.css" "NetworkError: 404 Not Found - localhost/css/player.css" "NetworkError: 404 Not Found - localhost/css/ui-lightness/jquery-ui-1.8.11.custom.css" "NetworkError: 404 Not Found - localhost/js/jquery.js" It seems my server is looking for the files in the wrong places. For example, localhost/css/popup.css is actually located at localhost/app/webroot/css/popup.css. I have my site setup on a remote server with the same exact configurations and it works perfectly fine. I am just having this issue trying to run the site on my laptop at localhost. I edited my VirtualHosts file DocumentRoot and to /home/user/public_html/site.com/public/app/webroot/ and this reduces some errors but I feel that this is wrong and sort of hacking it since I didn't use these setting on my production server which works. The last note I want to make is that the website uses dynamic URLs. I dont know if that has anything to do with it. For example, on the production server the URLS are: site.com/#hello/12321. HERES WHAT I AM WORKING WITH: I have a LAMP server setup on my laptop which runs on Ubuntu 11.10. I have enabled mod_rewrite: sudo a2enmod rewrite Then I edited my Virtual Hosts file: <VirtualHost *:80> ServerName localhost DirectoryIndex index.php DocumentRoot /home/user/public_html/site.com/public <Directory /home/user/public_html/site.com/public/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> </VirtualHost> Then I restarted apache. My website is using cakePHP. This is the directory structure of the website: "/home/user/public_html/site.com/public" contains: index.php app cake plugins vendors These are my .htaccess files: /home/user/public_html/site.com/public/app/.htaccess: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ webroot/ [L] RewriteRule (.*) webroot/$1 [L] </IfModule> /home/user/public_html/site.com/public/app/webroot/.htaccess: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] </IfModule>

• Why are emails sent from my applications being marked as spam?

  - by Brian

  Hi. I have 2 web apps running on the same server. The first is www.nimikri.com and the other is www.hourjar.com. Both apps share the same IP address (75.127.100.175). My server is through a shared hosting company. I've been testing my apps, and at first all my emails were being delivered to me just fine. Then a few days ago every email from both apps got dumped into my spam box (in gmail and google apps). So far the apps have just been sending emails to me and nobody else, so I know people aren't manually flagging them as spam. I did a reverse DNS lookup for my IP and the results I got were these: 100.127.75.in-addr.arpa NS DNS2.GNAX.NET. 100.127.75.in-addr.arpa NS DNS1.GNAX.NET. Should the reverse DNS lookup point to nimikri.com and hourjar.com, or are they set up fine the way they are? I noticed in the email header these 2 lines: Received: from nimikri.nimikri.com From: Hour Jar <[email protected]> Would the different domain names be causing gmail to think this is spam? Here is the header from one of the emails. Please let me know if any of this looks like a red flag for spam. Thanks.

• Block IP Address including ICMP using UFW

  - by dr jimbob

  I prefer ufw to iptables for configuring my software firewall. After reading about this vulnerability also on askubuntu, I decided to block the fixed IP of the control server: 212.7.208.65. I don't think I'm vulnerable to this particular worm (and understand the IP could easily change), but wanted to answer this particular comment about how you would configure a firewall to block it. I planned on using: # sudo ufw deny to 212.7.208.65 # sudo ufw deny from 212.7.208.65 However as a test that the rules were working, I tried pinging after I setup the rules and saw that my default ufw settings let ICMP through even from an IP address set to REJECT or DENY. # ping 212.7.208.65 PING 212.7.208.65 (212.7.208.65) 56(84) bytes of data. 64 bytes from 212.7.208.65: icmp_seq=1 ttl=52 time=79.6 ms ^C --- 212.7.208.65 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 79.630/79.630/79.630/0.000 ms Now, I'm worried that my ICMP settings are too generous (conceivably this or a future worm could setup an ICMP tunnel to bypass my firewall rules). I believe this is the relevant part of my iptables rules is given below (and even though grep doesn't show it; the rules are associated with the chains shown): # sudo iptables -L -n | grep -E '(INPUT|user-input|before-input|icmp |212.7.208.65)' Chain INPUT (policy DROP) ufw-before-input all -- 0.0.0.0/0 0.0.0.0/0 Chain ufw-before-input (1 references) ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 3 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 4 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 11 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 12 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 8 ufw-user-input all -- 0.0.0.0/0 0.0.0.0/0 Chain ufw-user-input (1 references) DROP all -- 0.0.0.0/0 212.7.208.65 DROP all -- 212.7.208.65 0.0.0.0/0 How should I go about making it so ufw blocks ICMP when I specifically attempt to block an IP address? My /etc/ufw/before.rules has in part: # ok icmp codes -A ufw-before-input -p icmp --icmp-type destination-unreachable -j ACCEPT -A ufw-before-input -p icmp --icmp-type source-quench -j ACCEPT -A ufw-before-input -p icmp --icmp-type time-exceeded -j ACCEPT -A ufw-before-input -p icmp --icmp-type parameter-problem -j ACCEPT -A ufw-before-input -p icmp --icmp-type echo-request -j ACCEPT I'm tried changing ACCEPT above to ufw-user-input: # ok icmp codes -A ufw-before-input -p icmp --icmp-type destination-unreachable -j ufw-user-input -A ufw-before-input -p icmp --icmp-type source-quench -j ufw-user-input -A ufw-before-input -p icmp --icmp-type time-exceeded -j ufw-user-input -A ufw-before-input -p icmp --icmp-type parameter-problem -j ufw-user-input -A ufw-before-input -p icmp --icmp-type echo-request -j ufw-user-input But ufw wouldn't restart after that. I'm not sure why (still troubleshooting) and also not sure if this is sensible? Will there be any negative effects (besides forcing the software firewall to force ICMP through a few more rules)?

• Varnish + Plesk : vhost broken

  - by Raphaël

  I have an e-commerce site with 300,000 products and 20,000 categories. It is slow and currently in production. I decided to install Varnish to speed up. The trouble is that during installation, I got a Guru Meditation. Since the site is in production, I am not allowed to leave this error more than a second, thinking to have made an enormous stupidity. I followed the following tutorial: http://www.euperia.com/linux/setting-up-varnish-with-apache-tutorial I'm sure I followed all without error. I say that there may be a specific configuration with plesk. Has anyone already installed Varnish on a ubuntu 11.04 server with plesk 10? Does anyone have a better resource? I know it is "very vague" as an error, but maybe some of you have had this problem. edit 24/11/2011 I continued to work on Varnish + Plesk ... but it still does not work. 1) I changed the port for apache in plesk General # mysql -uadmin -p`cat /etc/psa/.psa.shadow` -D psa -e'replace into misc (param, val) values ("http_port", 8008)' 1.1) I rebuild the server conf # /usr/local/psa/admin/bin/httpdmng --reconfigure-all 2) I changed the apache conf files (if those were not taking full plesk top) vim /etc/apache2/ports.conf NameVirtualHost *:8008 Listen 8008 2.1) I do the same with /etc/apache2/sites-enables/000-default 3) I changed the port of my vhost (a single server) vim /var/www/vhosts/MYDOMAIN.COM/conf/XXXXXXXXX.http.include Replace the port 80 by this I want. Rebuild the vhost conf /usr/local/psa/admin/sbin/websrvmng --reconfigure-vhost --vhost-name=<domain_name> with without www (See my issue in serverfault: Edit vhost port in plesk 10.3 ) 4) I installed varnish by following this tutorial : http://www.euperia.com/linux/setting-up-varnish-with-apache-tutorial 5) I restart apache 2 + varnish service apache2 restart service varnish restart When I go to my site, I come across a page of apache It works! This is the default web page for this server. The web server software is running but no content has been added, yet. Can somebody help me ? This means that my vhost does not point to the right place. Why? What to do? How?

• HID USB Very Strange Problem...

  - by Lasanha

  I realy hope some one can help me here cause i search all over the web and nothing comes up.. I allways used PS/2 KB and Mouse and a USB KeyPad (Genius ErgoMedia 500 Gaming Explorer) to play some games, mmorpg, fps, you named, very good whit 11 keys whit possible macros etc etc... Now it comes the problem, i have a USB mouse that have 4 extra buttons, and i need more button, i love buttons.. Well, i plug in the USB mouse and disconectes de PS/2. Everything is ok until i toutch the mouse. If i do so, the ErgoMedia goes off, then on, then i mouse the mouse or press a button and all over again. Yesterday i went buying a new mouse that i liked, a USB mouse too (NPlay whit macros and all that stuff 3600dpi...) Hoping the problem was only whit the other mouse, but no.. It does the exact same thing, ErgoMedia keeps disconecting and conecting everytime i toutch the mouse. What i allready did: Update drivers of both mouses Update drivers of ErgoMedia (no specific drivers(Windows based)) Update drivers of MB Chipset (Actualy no, cause it was up to date allready) Trying other USB Ports (4 Ports back, 4 Ports Front and even 1 Port in 16 card slot device) Disable the "Allows Windows to shut down the energy bla bla" thing in Device Setings. Look up in the Device Setings only apear a problem on the ergomedia (Human interface Device) when i move the damm mouse.. Using Everest to read behavier, everything normal, exepts the disconecting thing, but no errors. Not a power suply, only the ErgoMedia and the mouse are in the USBs, and i allready disable the 16 card reader whit one usb slot to see.. Clean the IRQ registry. Look the entire internet for a fix solution. Help others problems wile looking for a fix for me (Im not a pro but not a completly stupid) Talking to you beggin you to help me as a last resorce... Machine: Acer M3641 Core2Quad 64x Based OS Vista 64b 4GbRAM HD Audio and Graphics I realy hope some one out there knows a fix for this, maybe it´s a simple thing, so simple that i´m to stupid to see that.. Sorry for my bad inglish but i write lot of erros even in my language. Any help will be very welcome. Tanks for ur concern and atention ^^

• Apache and MySQL taking all the memory? Maximum connections?

  - by lpfavreau

  I've a had one of our servers going down (network wise) but keeping its uptime (so looks the server is not losing its power) recently. I've asked my hosting company to investigate and I've been told, after investigation, that Apache and MySQL were at all time using 80% of the memory and peaking at 95% and that I might be needing to add some more RAM to the server. One of their justifications to adding more RAM was that I was using the default max connections setting (125 for MySQL and 150 for Apache) and that for handling those 150 simultaneous connections, I would need at least 3Gb of memory instead of the 1Gb I have at the moment. Now, I understand that tweaking the max connections might be better than me leaving the default setting although I didn't feel it was a concern at the moment, having had servers with the same configuration handle more traffic than the current 1 or 2 visitors before the lunch, telling myself I'd tweak it depending on the visits pattern later. I've also always known Apache was more memory hungry under default settings than its competitor such as nginx and lighttpd. Nonetheless, looking at the stats of my machine, I'm trying to see how my hosting company got those numbers. I'm getting: # free -m total used free shared buffers cached Mem: 1000 944 56 0 148 725 -/+ buffers/cache: 71 929 Swap: 1953 0 1953 Which I guess means that yes, the server is reserving around 95% of its memory at the moment but I also thought it meant that only 71 out of the 1000 total were really used by the applications at the moment looking a the buffers/cache row. Also I don't see any swapping: # vmstat 60 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 57612 151704 742596 0 0 1 1 3 11 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 1 1 24 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 2 1 18 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 0 1 13 0 0 100 0 And finally, while requesting a page: top - 08:33:19 up 3 days, 13:11, 2 users, load average: 0.06, 0.02, 0.00 Tasks: 81 total, 1 running, 80 sleeping, 0 stopped, 0 zombie Cpu(s): 1.3%us, 0.3%sy, 0.0%ni, 98.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1024616k total, 976744k used, 47872k free, 151716k buffers Swap: 2000052k total, 0k used, 2000052k free, 742596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24914 www-data 20 0 26296 8640 3724 S 2 0.8 0:00.06 apache2 23785 mysql 20 0 125m 18m 5268 S 1 1.9 0:04.54 mysqld 24491 www-data 20 0 25828 7488 3180 S 1 0.7 0:00.02 apache2 1 root 20 0 2844 1688 544 S 0 0.2 0:01.30 init ...

• Cannot exit X server, restart, shutdown or drop to tty when VGA monitor active

  - by terdon

  I have a strange problem. If I connect an external VGA monitor to my laptop, exiting the X environment in any way crashes the computer. For example, say I am working with my two monitors (the laptop's and one connected to my VGA port) active. Hitting Ctrl+Alt+F Key should take me down to a tty. What actually happens is that the VGA screen goes blank, as you would expect, but the laptop screen, although still on, shows nothing. I know the screen is on because it is slightly more illuminated than when it is off. When in this state, I can do nothing to regain access to the machine. I have tried: Ctrl+F Key (and even Ctrl+Alt+F Key, just in case) combinations and none seem to have any effect. Ctrl+Alt+Del : Nothing Magic SysRq key: Nothing Blindly typing my username and password and trying to reboot/shutdown or restart GDM or MDM: Nothing The only thing that works is a hard reset. The exact same behavior occurs when kiling the X server through Ctrl+Alt+Backspace, rebooting or shutdown. There is no difference if I reboot/shutdown/log out using the WM's graphical menu or if I use the shutdown or rebootcommands. It is also not WM-dependent. I have the same problem using Cinnamon, Gnome 3, MATE and xfce4. It is, however, VGA dependent. I have tried connecting another VGA monitor and have the same problem. I do not, however, have this problem if a screen is connected to the DisplayPort. It is, therefore, a VGA specific issue. To make things even stranger, this only occurs when both screens are active. If either the laptop screen or the VGA monitor is inactive the problem goes away. Finally, this problem arose when I installed the latest Linux Mint Debian (LMDE). It did not occur with the previous release of LMDE. I am not sure what has changed since I used the same kernel version in both releases (I had upgraded the kernel while on the previous release) and, I think, the same nvidia drivers. Oh, and yes, I have updated the nvidia driver. Hardware: Dell M4500 laptop CPU: Intel Core i7 RAM: 8GB Graphics: nVidia GT216 [Quadro FX 880M] Software: LMDE, kernel 3.2.0-2-amd64 Xorg: 1.11.4 nVidia kernel: 295.20-1+3.2.9-1 Possibly relevant files: /var/log/Xorg.0.log ~/.xsession-errors Does anyone have any ideas how to fix this? Thanks in advance for any help.

• Debugging IO limitation

  - by Martin F

  I have a Fedora box with some severe IO limitations which I have no idea how to debug. The server has a Areca Technology Corp. ARC-1130 12-Port PCI-X to SATA RAID Controller with 12 7200 RPM 1.5 TB disks and a Marvell Technology Group Ltd. 88E8050 PCI-E ASF Gigabit Ethernet Controller. uname -a output: 2.6.32.11-99.fc12.x86_64 #1 SMP Mon Apr 5 19:59:38 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux The server is a file server running Nginx with the stub status module enabled, so I can see the current amount of connections. The problem present itself when I have a high number of simultaneous connections in a writing state. Usually around 350, at this very moment it's at 590 and the server is almost unusable and stuck at 230mbit/s. If I run stop and hit 1 to see CPU core usages I have all 4 cores with around 99% io wait, if I run iotop the nginx workers are the only processes producing any read load, currently at around 25MB/s. I have each of the workers bound to their own core. Initially I figured it was just the disks being bugged. But I've run fscheck and smartmontools checks and found no errors. I also ran an iozone test which you can see the result of here: http://www.pastie.org/951667.txt?key=fimcvljulnuqy2dcdxa Additionally, when the amount of connections are low I have no problem getting a good speed. If I wget over the local network it easily hits 60MB/sec. Right now I just tried putting a file in /dev/shm, then I symlinked a file from the public dir to it and used wget over the local network and only got 50KB/s. Also, if I try to cp /dev/shm/test /root/test it quickly copies around 740MB and then slows down HEAVILY. Again with iotop reporting 99% iowait. I'm not really sure how to go about figuring out what the problems are. It could be a natural disk limitation but then the file from /dev/shm ought to transfer so it seems there's a network limit, but that's fine when there's not many connections. Perhaps it's a TCP stack problem but I really have no idea how to check that. Any suggestions on how to proceed with debugging would be very welcome. If additional information is required then let me know and I'll try to get it. Thanks.

It's worth noting that the destination is just another vhost on the same apache instance, but the vhost (http://api.myservice.org) is serving passenger (mod_rails) I was thinking that maybe there's some startup issues with the passenger workers not being ready during a graceful restart?

• Linux Fiber Channel Host Setup Basic

  - by Jim

  I've been googling for about 4 hours now with no luck. I am trying to setup a Linux server running Oracle Server 6.3 as a Fiber Channel host. And then connect it to a Dell Compellent Fibre Channel Host contain a 500GB Volume. The Oracle server itself contains two Brocade 815 FC HBAs. I've discovered their WWN(I think) via cat /sys/class/fc_host/host1/port_name 0x100000051efc3d85 cat /sys/class/fc_host/host2/port_name 0x100000051efc3d9f The next part is where I am at a loss. I've used iSCSI before...is FC the same deal where you have an initiator and a target? If so where do I specific that in linux? I'm also new to Fiber Channel as a protocol, so i am unsure what is needed to make a transaction? WWN and port ID? Similar to IP:Port combination in the Ethernet world. I've read alot regarding using systool, multipath, fc_transport commands, however none of these is recognized as a valid command from Oracle Server 6.3 Appreciate the guidance and assistance. I installed sccsi-target-utils and can now run rescan-scsi-bus and sg_map -x. rescan-scsi-bus.sh -l -w -r Host adapter 0 (megaraid_sas) found. Host adapter 1 ((null)) found.

• Force Finder to log in as Guest to a SMB share

  - by slhck

  I have a QNAP NAS that offers a few SMB shares. As I'm in a trusted environment, my shares are accessible as guest rather than with a combination of username and password. Problem Now, when I click the name of the device in Finder's sidebar, I get the black "Connection failed" bar, with the option "Connect as...". When I click that, I receive: I can however press ? + K and enter the server's name manually, which gets me to this window: Here, I have to select "guest". Now, I can select one of the shares to connect to, and I'm finally connected to the server. If I select it in the sidebar, I get a list of all shares available, because I'm connected as "guest", obviously: What I need Well, as soon as I unmount all shares, I have to go through the same procedure of manually logging in as "guest" again, which I find quite annoying. Is there any way I could get Finder (or the underlying SMB client) to know which credentials to use? Or should I look for the solution rather on the server side? (I know that other SMB shares seem to work fine in my network) Diagnostics The only thing I can get out of Console.app is: 5/15/11 7:36:40 PM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[200] SharePointBrowser::handleOpenCallBack returned 64 This message occurs when I click the name of the SMB server in the Finder sidebar. Here's the output of `smbclient -L meredith -U guest -d=2 charon:~ werner$ smbclient -L meredith -U guest -d=2 added interface ip=192.168.100.11 bcast=192.168.100.255 nmask=255.255.255.0 tdb(unnamed): tdb_open_ex: could not open file /private/var/samba/gencache.tdb: Permission denied Got a positive name query response from 192.168.100.100 ( 192.168.100.100 ) Password: Domain=[MEREDITH] OS=[Unix] Server=[Samba 3.5.2] Sharename Type Comment --------- ---- ------- music Disk movies Disk photos Disk software Disk archive Disk backups Disk IPC$ IPC IPC Service (NAS Server) Got a positive name query response from 192.168.100.100 ( 192.168.100.100 ) Domain=[MEREDITH] OS=[Unix] Server=[Samba 3.5.2] Server Comment --------- ------- Workgroup Master --------- ------- WORKGROUP MEREDITH Also, things I've tried: There is no relevant entry in the Keychain (but why would it, I'm only connecting as guest) Connecting with user name "Guest" and empty password logs me in but still after ejecting the last share, I get the same "Connection failed" error as before. The appropriate entry is made in the Keychain but obviously has no effect.
