In case you have installed Ubuntu oneiric and notice a dbus error at boot, here is the fix:

1) create directories /run and /run/lock,
2) move contents of /var/run into /run and /var/lock into /run/lock,
3) delete directories /var/run and /var/lock
4) create replacement simlinks; e.g. ‘ln -s /run /var/run’ and ‘ln -s /run/lock /var/lock’

Reboot, and things should be back to normal.

If you install this configuration in /etc/apache2/conf.d + libapache2-mod-fcgid, then you can use either version of apache2 with php5.

First add the programs indicated and then add the script below to  /etc/apache2/conf.d:

apt-get install apache2-mpm-worker  libapache2-mod-fcgid
a2enmod fcgid
aptitude install php5-cgi php5-cli
###00-fcgi###
<Directory /var/www>
AddHandler fcgid-script .php
FCGIWrapper /usr/lib/cgi-bin/php5 .php
Options +ExecCGI
</Directory>
Alias /aptitude /usr/share/doc/aptitude/html/en
Alias /apt /usr/share/doc/apt-doc

<Directory /usr/share>
AddHandler fcgid-script .php
FCGIWrapper /usr/lib/cgi-bin/php5 .php
Options ExecCGI FollowSymlinks Indexes
</Directory>

<IfModule mod_actions.c>
Action application/x-httpd-php /cgi-bin/php5
</IfModule>

With the above additions,  you can run apache2-mpm-worker or apt-get install apache2-mpm-prefork and either will run. Of course if you prefer to use the php apache module with apache2-mpm-prefork, you can add that with apt and remove the above script from conf.d

You can search and replace and IP address in bind (named.conf) or name server records with this script:

Assign values as indicated.

#!/bin/bash
x=`cat oldip`
a=`cat newip`
cmd=”sed -e”
$cmd “s#$x#$a#g” oldconfigfie > new.configfile

You can use the script below to parse your maillog (mail.log on Debian based distros) for failed login attempts and place the results in your hosts.deny file or your IP tables config. The script deletes leading 0 IP addresses and filters out [brackets]. You can change the grep filter phrase to your liking.

grep “failed” /var/log/maillog | grep -Eo “([0-9]{1,3}.){3}[0-9]{1,3}” | sed ‘s/^[0]*//’ | uniq
