• Recommended setting for using Apache mod_mono with a different user

  - by Korrupzion

  Hello, I'm setting up an ASP.net script in my linux machine using mod_mono. The script spawn procceses of a bin that belongs to another user, but the proccess is spawned by www-data because apache runs with that user, and i need to spawn the proccess with the user that owns the file. I tried setuid bit but it doesn't make any effect. I discovered that if I kill mod-mono-server2.exe and I run it with the user that I need, everything works right, but I want to know the proper way to do this, because after a while apache runs mod-mono-server2.exe as www-data again. Mono-Project webpage says: How can I Run mod-mono-server as a different user? Due to apache's design, there is no straightforward way to start processes from inside of a apache child as a specific user. Apache's SuExec wrapper is targeting CGI and is useless for modules. Mod_mono provides the MonoStartXSP option. You can set it to "False" and start mod-mono-server manually as the specific user. Some tinkering with the Unix socket's permissions might be necessary, unless MonoListenPort is used, which turns on TCP between mod_mono and mod-mono-server. Another (very risky) way: use a setuid 'root' wrapper for the mono executable, inspired by the sources of Apache's SuExec. I want to know how to use the setuid wrapper, because I tried adding the setuid to 'mono' bin and changing the owner to the user that I want, but that made mono crash. Or maybe a way to keep running mono-mod-server2.exe separated from apache without being closed (anyone has a script?) My environment: Debian Lenny 2.6.26-2-amd64 Mono 1.9.1 mod_mono from debian repository Dedicated server (root access and stuff) Using apache vhosts -I use mono for only that script Thanks!

• Apache Won't Restart After Compiling PHP with Postgres

  I've compiled PHP (v5.3.1) with Postgres using the following configure: ./configure \ --build=x86_64-redhat-linux-gnu \ --host=x86_64-redhat-linux-gnu \ --target=x86_64-redhat-linux-gnu \ --program-prefix= \ --prefix=/usr/ \ --exec-prefix=/usr/ \ --bindir=/usr/bin/ \ --sbindir=/usr/sbin/ \ --sysconfdir=/etc \ --datadir=/usr/share \ --includedir=/usr/include/ \ --libdir=/usr/lib64 \ --libexecdir=/usr/libexec \ --localstatedir=/var \ --sharedstatedir=/usr/com \ --mandir=/usr/share/man \ --infodir=/usr/share/info \ --cache-file=../config.cache \ --with-libdir=lib64 \ --with-config-file-path=/etc \ --with-config-file-scan-dir=/etc/php.d \ --with-pic \ --disable-rpath \ --with-pear \ --with-pic \ --with-bz2 \ --with-exec-dir=/usr/bin \ --with-freetype-dir=/usr \ --with-png-dir=/usr \ --with-xpm-dir=/usr \ --enable-gd-native-ttf \ --with-t1lib=/usr \ --without-gdbm \ --with-gettext \ --without-gmp \ --with-iconv \ --with-jpeg-dir=/usr \ --with-openssl \ --with-zlib \ --with-layout=GNU \ --enable-exif \ --enable-ftp \ --enable-magic-quotes \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --enable-sysvmsg \ --with-kerberos \ --enable-ucd-snmp-hack \ --enable-shmop \ --enable-calendar \ --with-libxml-dir=/usr \ --enable-xml \ --with-system-tzdata \ --with-mime-magic=/usr/share/file/magic \ --with-apxs2=/usr/sbin/apxs \ --with-mysql=/usr/include/mysql \ --without-gd \ --with-dom=/usr/include/libxml2/libxml \ --disable-dba \ --without-unixODBC \ --disable-pdo \ --enable-xmlreader \ --enable-xmlwriter \ --without-sqlite \ --without-sqlite3 \ --disable-phar \ --enable-fileinfo \ --enable-json \ --without-pspell \ --disable-wddx \ --with-curl=/usr/include/curl \ --enable-posix \ --with-mcrypt \ --enable-mbstring \ --with-pgsql=/mnt/mv/pgsql I'm using Postgres 8.4.0 and Apache 2.2.8; I have the following line in my Apache conf file: LoadModule php5_module /usr/lib64/httpd/modules/libphp5.so And when I attempt to restart Apache, I get the following error message: Starting httpd: httpd: Syntax error on line 205 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib64/httpd/modules/libphp5.so into server: /usr/lib64/httpd/modules/libphp5.so: undefined symbol: lo_import_with_oid Now, I know that this is a problem with Postgres with PHP because lo_import_with_oid is a function in the Postgres source which allows the importing of large objects; also, if I remove the --with-pgsql option, PHP and Apache get along great. I've scoured the Internet looking for answers all day, but to no avail. Does anyone have ANY insight into what is causing my problems.

• Apache & SVN on Ubuntu - Post-commit hook fails silently, pre-commit hook “Permission Denied”

  - by 113169587962668775787

  I've been struggling for the past couple days to get post-commit email notifications working on my SVN server (running via HTTP with Apache2 on Ubuntu 9.10). SVN commits work fine, but for some reason the hooks are not being properly executed. Here are the configuration settings: - Users access the repo via HTTP with the apache dav_svn module (I created users/passwords via htpasswd in a dav_svn.passwd file). dav_svn.conf: <Location /svn/repos> DAV svn SVNPath /home/svn/repos AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd Require valid-user </Location> I created a post-commit hook file that writes a simple message to a file in the repository root: /home/svn/repos/hooks/post-commit: #!/bin/sh REPOS="$1" REV="$2" /bin/echo 'worked' > ${REPOS}/postcommit.log I set the entire repository to be owned by www-data (the apache user), and assigned 755 permissions to the post-commit script when I test the post-commit script using the www-data user in an empty environment, it works: sudo -u www-data env - /home/svn/repos/hooks/post-commit /home/svn/repos 7 But when I commit on a client machine, the commit is successful, but the post-commit script does not seem to be executed. I also tried running a simple script for the pre-commit hook, and I get an error, even with an empty pre-commit script: "Commit failed (details follow): Can't create null stdout for hook '/home/svn/repos/hooks/pre-commit': Permission denied" I did a few searches on Google for this error and I presume that this is an issue with the apache user (www-data) not having adequate permissions, specifically to execute /dev/null. I also read that the reason post-commit fails silently is because that it doesn't report with stdout. Anyway, I've also tried giving the apache user (www-data) ownership of the entire repository, and edited the apache virtualhost to allow operations on the server root, and I'm still getting permission denied /etc/apache2/sites-available/primarydomain.conf <Directory /> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> Any ideas/suggestions would be greatly appreciated! Thanks

• How to verify PostgreSQL 9 has installed correctly on a CentOS server?

• SSL on local sub-domain and sub-sub-domain

  - by Eduard Luca

  I have both local.domain.com and lmarket.local.domain.com pointing to my localhost from etc/hosts. The problem is that I am using XAMPP on Windows 7, and have 2 SSL VirtualHosts in my apache config, but no matter which one I access, I am taken to local.domain.com. On non-HTTPS requests all works fine, and the vhosts are basically the same. Here is the relevant part of my vhosts: <VirtualHost local.domain.com:443> DocumentRoot "C:/xampp/htdocs/local" ServerName local.domain.com ServerAdmin webmaster@localhost ErrorLog "logs/error.log" <IfModule log_config_module> CustomLog "logs/access.log" combined </IfModule> SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile "conf/ssl.crt/server.crt" SSLCertificateKeyFile "conf/ssl.key/server.key" <FilesMatch "\.(cgi|shtml|pl|asp|php)$"> SSLOptions +StdEnvVars </FilesMatch> <Directory "C:/xampp/cgi-bin"> SSLOptions +StdEnvVars </Directory> BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 CustomLog "logs/ssl_request.log" "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b" </VirtualHost> <VirtualHost lmarket.local.domain.com:443> DocumentRoot "C:/xampp/htdocs/lmarket.local" ServerName lmarket.local.domain.com ServerAdmin webmaster@localhost ErrorLog "logs/error.log" <IfModule log_config_module> CustomLog "logs/access.log" combined </IfModule> SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile "conf/ssl.crt/server.crt" SSLCertificateKeyFile "conf/ssl.key/server.key" <FilesMatch "\.(cgi|shtml|pl|asp|php)$"> SSLOptions +StdEnvVars </FilesMatch> <Directory "C:/xampp/cgi-bin"> SSLOptions +StdEnvVars </Directory> BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 CustomLog "logs/ssl_request.log" "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b" </VirtualHost> If I invert these blocks, then the opposite happens: local.domain.com goes to lmarket.local.domain.com. Any help would be appreciated.

• Can't install NPM after installing Node on EC2 Linux instance?

  - by frequent

  I'm trying my first attempt on getting a node server set up on an amazon ec2 linux instance. I think I made it quite far. First problem I ran into was when trying to make Node the connection timed out after a while, so I need three attempts until I got this: LINK(target) /home/ec2-user/node/out/Release/node: Finished touch /home/ec2-user/node/out/Release/obj.target/node_dtrace_header.stamp touch /home/ec2-user/node/out/Release/obj.target/node_dtrace_provider.stamp touch /home/ec2-user/node/out/Release/obj.target/node_dtrace_ustack.stamp touch /home/ec2-user/node/out/Release/obj.target/node_etw.stamp make[1]: Leaving directory `/home/ec2-user/node/out' ln -fs out/Release/node node Which tells me, "Node is done", although I'm not sure it is also working as it should. Following this,this and this tutorial, I'm now stuck at installing npm. I think I first cloned into the wrong folder, which always gave me error 127, but even if I'm doing this: cd ~ git clone git://github.com/isaacs/npm.git cd npm sudo -s PATH=/usr/local/bin:$PATH make install I'm still getting this: #after cloning# make[1]: Entering directory `/root/npm' node cli.js install bash: node: command not found make[1]: *** [node_modules/.bin/ronn] Error 127 make[1]: Leaving directory `/root/npm' make: *** [man/man3/start.3] Error 2 Question:: Since I'm pretty much a newby at everything I'm trying here, can someone please tell me what I'm doing wrong and how to get npm to install? Also, in case I cloned into the wrong folder, is there a way to remove the "false clone" or is this not written to disk until I call make install and I don't need to worry? Thanks for helping out!

• Bash script 'while read' loop causes 'broken pipe' error when run with GNU Parallel

  - by Joe White

  According to the GNU Parallel mailing list this is not a GNU Parallel-specific problem. They suggested that I post my problem here. The error I'm getting is a "broken pipe" error, but I feel I should first explain the context of my problem and what causes this error. It happens when trying to use any bash script containing a 'while read' loop in GNU Parallel. I have a basic bash script like this: #!/bin/bash # linkcheck.sh while read domain do host "$domain" done Assume that I want to pipe in a large list (250mb say). cat urllist | ./linkcheck.sh Running host command on 250mb worth of URLs is rather slow. To speed things up I want to break up the input into chunks before piping it and then run multiple jobs in parallel. GNU Parallel is capable of doing this. cat urllist | parallel --pipe -j0 parallel ./linkcheck.sh {} {} is substituted by the contents of urllist line-by-line. Assume that my systems default setup is capable of running 500ish jobs per instance of parallel. To get round this limitation we can parallelize Parallel itself: cat urllist | parallel -j10 --pipe parallel -j0 ./linkcheck.sh {} This will run 5000'ish jobs. It will also, sadly, cause the error "broken pipe" (bash FAQ). Yet the script starts to work if I remove the while read loop and take input directly from whatever is fed into {} e.g., #!/bin/bash # linkchecker.sh domain="$1" host "$1" Why will it not work with a while read loop? Is it safe to just turn off the SIGPIPE signal to stop the "broken pipe" message, or will that have side effects such as data corruption? Thanks for reading.

• Redmine install not working and displaying directory contents - Ubuntu 10.04

  - by Casey Flynn

  I've gone through the steps to set up and install the redmine project tracking web app on my VPS with Apache2 but I'm running into a situation where instead of displaying the redmine app, I just see the directory contents: Does anyone know what could be the problem? I'm not sure what other files might be of use to diagnose what's going on. Thanks! # # Based upon the NCSA server configuration files originally by Rob McCool. # # This is the main Apache server configuration file. It contains the # configuration directives that give the server its instructions. # See http://httpd.apache.org/docs/2.2/ for detailed information about # the directives. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # The configuration directives are grouped into three basic sections: # 1. Directives that control the operation of the Apache server process as a # whole (the 'global environment'). # 2. Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log" # with ServerRoot set to "" will be interpreted by the # server as "//var/log/apache2/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE!

• Problem running mysql client, cannot connect to mysql server

  - by ehsanul

  Edit3: Thanks for the help everyone. Sorry for wasting anybody's time, but it seems like a simple reboot solved it. I should've known better, but I just had the assumption that the "restart" solution is mostly valid just for MS Windows (no offense). I'll keep this in mind before I ask a question here again. I installed the mysql-client-5.0 and mysql-server-5.0 packages on Ubuntu 8.04, using sudo apt-get install. When I try to run the "mysql" command, I get the following error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) To verify that mysql server is running, I tried this, and it does seem to be running, with the correct socket too: $ ps aux | grep mysql root 13388 0.0 0.0 1772 528 ? S 06:24 0:00 /bin/sh /usr/bin/mysqld_safe mysql 13553 0.0 1.4 127012 15332 ?

Note that I'm completely new to mysql. Edit: As requested in comments, the exact command that is returning the error is simply "sudo mysql". And when I check netstats for active networks services, I do see an entry for port 3306, with Protocol: tcp, IP Source: 127.0.0.1, State: LISTEN Edit2: It appears as if the /var/run/mysqld/mysqld.sock socket doesn't exist (if I'm interpreting the following output correctly): $ ls -al /var/run/mysqld/ total 0 drwxr-xr-x 2 mysql root 40 2009-08-06 06:36 . drwxr-xr-x 20 root root 860 2009-08-06 06:25 ..

• multiple php compiler on single apache installation

  - by getmizanur

  elloo, i have some old php scripts which runs on php-5.2.x and the current server has php-5.3.x. to get around this problem,i have got two options one is to downgrade php-5.3.x or install php-5.2.x and php-5.3.x at the same time where php-5.2.x serve cgi script. i have decided go for the second option i have followed this tutorial and i can get most of it working however except execution of shell script which selects php-cgi version. i cannot get apache to execute this script. how do i get apache to execute #!/bin/sh # you can change the PHP version here. version="5.2.6" # php.ini file location, */php-5.2.6/lib equals */php-5.2.6/lib/php.ini. PHPRC=/etc/php/phpfarm/inst/php-${version}/lib/php.ini export PHPRC PHP_FCGI_CHILDREN=3 export PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS=5000 export PHP_FCGI_MAX_REQUESTS # which php-cgi binary to execute exec /etc/php/phpfarm/inst/php-${version}/bin/php-cgi my apache vhost.conf <VirtualHost *:80> ServerName 526.localhost DocumentRoot /home/getmizanur/public_html/www <Directory "/home/getmizanur/public_html/www"> AddHandler php-cgi .php Action php-cgi /php-fcgi/php-cgi-5.2.6 </Directory> </VirtualHost> can some one tell me what am i doing wrong? thanks in advance. solution: if i did a2dismod php5 then the above configuration worked. when a2enmod php5 had been activated, apache was executing php5.3 instead of php5.2 even after telling apache to execute php5.2 shell script. to solve my problem, i had to change my virtualhost configuration <VirtualHost *:80> ServerName 526.localhost DocumentRoot /home/getmizanur/public_html/www DirectoryIndex index.php <Directory "/home/getmizanur/public_html/www"> AddHandler php-cgi .php Action php-cgi /php-fcgi/php-cgi-5.2.6 <FilesMatch "\.php"> SetHandler php-cgi </FilesMatch> </Directory> </VirtualHost> presto, it started working.

• Run script before shutdown/restart

  - by dtbarne

  I'd like to run a PHP script when an instance is told to shutdown, but of course before it actually finishes shutting down. My particular script is just looking to push some log files from the local partition to a another server. I've got the gist of how this process works, but I need some clarification. How I understand it. Please correct me if I'm wrong. Create an executable script in /etc/init.d (lets call it /etc/init.d/push-logs) Create a symlink to /etc/init.d/push-logs from /etc/rc0.d (shutdown) and /etc/rc6.d (reboot). The name should be KXXpush-logs Here's my questions: Of course - am I understanding correctly? For #2 above - it sounds like the lower the XX the better - is there too low a number I can use? Does it matter if it shares a number with another script? Does the script in /etc/init.d/push-logs HAVE to follow the standard init.d template (supporting start/stop, etc. commands)? This doesn't really apply to my use case. If possible I just want the script to be the following: #!/bin/sh # # Run PHP file prior to shutdown # /usr/bin/php /path/to/php_file.php

• Cant connect to MySQL server from Java application

  - by RN

  This is on VPS\Centos server. The MySQL server is pre configured. I am running the Java application on Tomcat My Java web application is not able to connect to the MySQL server. I get an error - "Caused by: java.net.ConnectException: Connection refused" I suspect this to be a configuration problem rather than a coding problem- hence I have posted this on ServerFault And yes, The same web-app is able to connect to MySQL on a different linux box This is the URL that I provided to my Java application (note- it assumes default port) url = "jdbc:mysql://localhost/pickupgames" My first suspicion was that I am running on a non-default port So I tried to find the port where mySQL server is running I tried every trick mentioned in http://serverfault.com/questions/116100/how-to-check-what-port-mysql-is-running-on But no luck ! SHOW GLOBAL VARIABLES LIKE 'PORT'; This shows port 0 netstat -tlnp doesn't show mysql at all /etc/my.cnf It has no port entry telnet localhost 3306 Doesn't connect And in case you are wondering if mysql server is running at all or not It is And I know for sure, because I have been able to login using the mysql command Also # ps -ef|grep 'mysql' root 31839 27662 0 00:49 pts/3 00:00:00 grep mysql root 32452 1 0 Apr02 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe --skip-grant-tables --skip-networking mysql 32504 32452 0 Apr02 ? 00:00:06 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --socket=/var/lib/mysql/mysql.sock --skip-grant-tables --skip-networking Please note the --skip-networking parameter Does this have something to do with the issue ? Any explanation why I cant connect to mysql server on port 3306 by telnet? Or why it docent show up under netstat? Any suggestion on whet I should try next ?

• Apache to read from /home/user/public_html on CentOS 5.7

  - by C.S.Putra

  this is my first experience using CentOS 5.7 / Linux as my web server OS and I have just finished installing Apache. Then I created a new account using WHM. The account is now created and the domain name can be accessed. I have put the web files under /home/user/public_html/ but when I access the domain assigned for that user which I assigned when creating new account in WHM, it doesn't read the files. In /usr/local/apache/conf/httpd.conf : <VirtualHost 175.103.48.66:80> ServerName domain.com ServerAlias www.domain.com DocumentRoot /home/user/public_html ServerAdmin [email protected] User veevou # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup group1 group1 </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup group1 group1 </IfModule> CustomLog /usr/local/apache/domlogs/domain.com-bytes_log "%{%s}t %I .\n%{%s}t %O ."

How to set the apache so that when user access www.domain.com, they will access the files under /home/user/public_html/ ? Please advice. Thanks

• openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

  - by JoJoeDad

  I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server. Here's what I've done. 1) I do a test connect using openssl to see what the acceptable client certificate CA names are for my server, I issue this command from my client machine to my server: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -prexit and part of what I get back is as follow: Acceptable client certificate CA names /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] 2) Here is what is in the apache configuration file on the server regarding SSL client authentication: SSLCACertificatePath /etc/apache2/certs SSLVerifyClient require SSLVerifyDepth 10 3) I generated a self-signed client certificate called "client.pem" using mypos.pem and mypos.key, so when I run this command: openssl x509 -in client.pem -noout -issuer -subject -serial here is what is returned: issuer= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] subject= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=mlR::mlR/[email protected] serial=0E (please note that mypos.pem is in /etc/apache2/certs/ and mypos.key is saved in /etc/apache2/certs/private/) 4) I put client.pem on the client machine, and on the client machine, I run the following command: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -status -cert client.pem and I get this error: CONNECTED(00000003) OCSP response: no response sent depth=1 /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] verify error:num=19:self signed certificate in certificate chain verify return:0 574:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s3_pkt.c:1102:SSL alert number 48 574:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_lib.c:182: I'm really stumped as to what I've done wrong. I've searched quite a bit on this error and what I found is that people are saying the issuing CA of the client's certificate is not trusted by the server, yet when I look at the issuer of my client certificate, it matches to one of the accepted CA returned by my server. Can anyone help, please? Thank you in advance.

• Cannot connect to server via SSH

  - by Rayne

  I'm running RHEL 6.0, and I accidentally moved the /bin, /boot, /cgroup, console.txt, /data, /dev, /etc to another folder. I think I managed to move these folders back, but now I'm having trouble connecting to the server using SSH, but am able to access the server via VNC. When I tried to connect to the server using a terminal from another server, I get the error ssh_exchange_identification: Connection closed by remote host I'm currently still connected via SSH to the server (haven't closed the window yet), and am still able to access it normally. But if I try to open a new SSH terminal from my current session, I see /bin/bash: Permission denied If I try to open a new SSH File Transfer window from my current session, I get the error File transfer server could not be started or it exited unexpectedly. Exit value 0 was returned. Most likely the sftp-server is not in the path of the user on the server-side I checked and I have Subsystem sftp /usr/libexec/openssh/sftp-server which is the same path as the output of locate sftp-server Also, when I tried to restart sshd, I get the error Couldn't open /dev/null: Permission denied But my /dev/null has the permissions crw-rw-rw- for root,root. How can I resolve this? ETA: Thanks for all your help! I was able to start ssh by running the application directly /usr/sbin/sshd Even though the status of the openssh-daemon is still "stopped".

• Postgresql base backup script

  - by Terry Lorber

  I'm using the following script to do a file-level backup of Postgresql. I sometimes see that the last part, to do cleanup after "pgs_backup_stop" is called, hangs while it waits for the last WAL to be created. The REF_FILE to search for is sometimes wrong. I'm also shipping these files to a different machine, every 5 minutes via rsync. What do other people do to safely remove old WAL files? #!/bin/bash PGDATA=/usr/local/pgsql/data WAL_ARCHIVE=/usr/local/pgsql/archives PGBACKUP=/usr/local/pgsqlbackup PSQL=/usr/local/pgsql/bin/psql today=`date +%Y%m%d-%H%M%S` label=base_backup_${today} echo "Executing pg_start_backup with label $label in server ...

• How do I install PHP 5.3 on CentOS?

  - by fivelitresofsoda

  I have to install PHP 5.3 on my CentOS server. If I do yum install php, the base repository installs 5.1.6 which is too old for the applications I need to install. So I've been trying to use the IUS repository, following the official instructions from IUS: root@linuxbox ~]# wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-2.ius.el5.noarch.rpm root@linuxbox ~]# wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm root@linuxbox ~]# rpm -Uvh ius-release*.rpm epel-release*.rpm OK. Now I simply do yum install php53, etc. for all I need... but I get this error: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Check Error: file /usr/bin/php from install of php53u-cli-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-cli-5.1.6-27.el5_5.3.x86_64 file /usr/bin/php-cgi from install of php53u-cli-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-cli-5.1.6-27.el5_5.3.x86_64 file /usr/share/man/man1/php.1.gz from install of php53u-cli-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-cli-5.1.6-27.el5_5.3.x86_64 file /etc/php.ini from install of php53u-common-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-common-5.1.6-27.el5_5.3.x86_64 Error Summary ------------- I have no idea on how to solve this.

• Can't connect to local MySQL server through socket

  - by Martin

  I was trying to tune the performance of a running mysql-server by running this command: mysqld_safe --key_buffer_size=64M --table_cache=256 --sort_buffer_size=4M --read_buffer_size=1M & After this i'm unable to connect mysql from the server where mysql is running. I get this error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) However, luckily i can still connect to mysql remotely. So all my webservers still have access to mysql and are running without any problems. Because of this though i don't want to try to restart the mysql server since that will probably mess everything up. Now i know that mysqld_safe is starting the mysql-server, and since the mysql server was already running i guess it's some kind of problem with two mysql servers running and listening to the same port. Is there some way to solve this problem without restarting the initial mysql server? UPDATE: This is what ps xa | grep "mysql" says: 11672 ? S 0:00 /bin/sh /usr/bin/mysqld_safe 11780 ? Sl 175:04 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306 11781 ?

• How do I switch java versions to an earlier version in Fedora 17?

  - by JHutson456

  I just installed Fedora 17. I'm setting up the Android Build Environment and need Java. I downloaded and installed jdk-6u32-linux-amd64.rpm I ran java -version and it spit out the correct version. Well a day or two later i tried my first compile in Fedora 17 and it complained about java and failed. I ran java -version again and low and behold it spits out $ java -version java version "1.7.0_03-icedtea" OpenJDK Runtime Environment (fedora-2.1.fc17.7-x86_64) OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode) I'm stumped. I mean, i've run the update/upgrade commands since i installed but i didn't think that updated full version revisions... So, I ran alternatives --config java and that only gave me the java 1.7 version. While digging around more I discovered that the recommended version of Java for the build environment is jdk-6u27-linux-x64-rpm.bin so I downloaded that from here: Oracle Download When I ran: sudo sh jdk-6u27-linux-x64-rpm.bin it returned: Unpacking...

• Make router forward HTTP and HTTPS traffic to external App

  I use a Linksys WRT54GL router with DD-WRT v24-sp2 (10/10/09) std (SVN revision 13064) which I am trying to make forward all HTTP and HTTPS traffic to an external app called Fiddler (used as proxy) on port 8888. After a lot of digging on this site, dd-wrt forum, dd-wrt.com and WWW, I am stacked with the following piece of code that works (thanks to the guys from dd-wrt support for this info), but only for forwarding HTTP traffic (port 80): #!/bin/sh PROXY_IP=1234567890 PROXY_PORT=8888 LAN_IP=`nvram get lan_ipaddr` LAN_NET=$LAN_IP/`nvram get lan_netmask` iptables -t nat -A PREROUTING -i br0 -s $LAN_NET -d $LAN_NET -p tcp --dport 80 -j ACCEPT iptables -t nat -A PREROUTING -i br0 -s ! $PROXY_IP -p tcp --dport 80 -j DNAT --to $PROXY_IP:$PROXY_PORT iptables -t nat -I POSTROUTING -o br0 -s $LAN_NET -d $PROXY_IP -p tcp -j SNAT --to $LAN_IP iptables -I FORWARD -i br0 -o br0 -s $LAN_NET -d $PROXY_IP -p tcp --dport $PROXY_PORT -j ACCEPT I tried to edit the code from above and I came up with the following but it's still not forwarding HTTPS but just HTTP traffic: #!/bin/sh PROXY_IP=1234567890 PROXY_PORT=8888 LAN_IP=`nvram get lan_ipaddr` LAN_NET=$LAN_IP/`nvram get lan_netmask` iptables -t nat -A PREROUTING -i br0 -s $LAN_NET -d $LAN_NET -p tcp -m multiport --dports 80,443 -j ACCEPT iptables -t nat -A PREROUTING -i br0 -s ! $PROXY_IP -p tcp -m multiport --dports 80,443 -j DNAT --to $PROXY_IP:$PROXY_PORT iptables -t nat -I POSTROUTING -o br0 -s $LAN_NET -d $PROXY_IP -p tcp -j SNAT --to $LAN_IP iptables -I FORWARD -i br0 -o br0 -s $LAN_NET -d $PROXY_IP -p tcp --dport $PROXY_PORT -j ACCEPT I am not sure if is possible to forward HTTPS traffic anymore by just using a router so I'd appreciate if somebody will share his thoughts and/or examples regarding this subject here. Thanks!
