Did ispconfig add an apps and php-fcgi-scripts directorys and add a virtual host to 8081? When I did an update with ispconfig to 3.2 these appeared about the same time? If ispconfig did add these, what are they?
ISPConfig is not killing a port, it is using a port. Please see here: http://www.howtoforge.com/forums/showthread.php?t=44013&page=3&highlight=8081
To further this discussion: It appears that someone with knowledge of ISPConfig 3 had hacked into my server. They created an apps.vhost on port 8081. Directory /var/www/apps contained: drwx------ 2 ispapps ispapps 4096 Mar 13 11:32 . drwxr-xr-x 12 root root 4096 Mar 13 09:54 .. -rw-r--r-- 1 ispapps ispapps 33 Mar 11 22:08 .bash_logout -rw-r--r-- 1 ispapps ispapps 176 Mar 11 22:08 .bash_profile -rw-r--r-- 1 ispapps ispapps 124 Mar 11 22:08 .bashrc and a directory /var/www/php-fcgi-scripts contained: drwxr-xr-x 4 root root 4096 Mar 11 22:08 . drwxr-xr-x 12 root root 4096 Mar 13 09:54 .. drwxr-xr-x 2 ispapps ispapps 4096 Mar 13 11:37 apps drwxr-xr-x 2 ispconfig ispconfig 4096 Mar 13 11:37 ispconfig Each of these directories contained: .php-fcgi-starter which the contents were: #!/bin/sh PHPRC=/etc/ export PHPRC export PHP_FCGI_MAX_REQUESTS=5000 export PHP_FCGI_CHILDREN=8 exec /usr/lib/cgi-bin/php -d magic_quotes_gpc=off[ This somehow connected to a virtual machine hidden in one of my websites. I 'rm -fR' all that was not supposed to be there and rebooted the server. Now the server runs like it is supposed to. Fast at 10Mbps up and down. I have dumped using mod_php and am using suphp. Maybe the proper word is terminated not killed.
Thats the default ispconfig apps vhost which is part of ispconfig, to delete it was a very bad idea as you now messed up our setup. If you would have read the thread that I posted above, you should have seen that as it contained the instructions on how to change the port in case that its in use on your server already.
