Armed with a few RPMs I need to install on multiple machines and sick of SCP’ing files around machines I decided to set up a Yum repository. Here’s how: On a machine that already has Apache running and serving content: yum install createrepo cd /var/www/html/centos/5/qub/x86_64 createrepo /var/www/html/centos/5/qub/x86_64 Then on each client machine aiming to use… Read more »

Since I like posting screeshots of uptime figures here is one of an anti-spam machine up for 1496 days (just over 4 years). The machine is running Red Hat 4.
Background: I made a tar backup of one system and wanted to untar that onto different hardware. A bit like cloning. However I needed to make sure the hostname and network settings were those of the new machine and not the cloned machine. So for future reference … Change the Hostname vi /etc/hosts Change the… Read more »
Background: I had an existing CentOS machine as a virtual machine running on VMWare ESX Server and it was running out of space so for future reference I did the following. Incidentally my disk is sda with the new partition create on the extra space as sda3. I first increased the disk using the vSphere… Read more »
These are the steps I took to create a centralised location of system logs. In this scenario multiple servers (earth, venus, mars) send their system logs to a central server (sun 192.168.1.1). I’m not going to cover the configuration of Apache, MySql except were it applies to Log Analyzer. Most of the servers are running… Read more »
Uptime of 1214 days on an internal email scanning server running Red Hat Linux 4.
If you plan to use URLBlacklist.com or Shalla rules in Dansguardian you may suffer from very slow (or impossible) restarts of the daemon. Dansguardian prefers the rules randomized rather than in alphabetical order. I couldn’t find the randomize lines package in the repos so compiled it first e.g.: wget http://arthurdejong.org/rl/rl-0.2.7.tar.gztar xzf rl-0.2.7.tar.gzcd rl-0.2.7./configuremakemake install Then… Read more »
After putting together an RPM for DansGuardian v126.96.36.199 I thought I would make a few notes. The version of DansGuardian in the repositories is currently version 2.8 and the only other repo or rpm I could find was a 32-bit 2.10. Why DansGuardian 2.10? Content Scanning Support with Clamd or Kapersky Regular Expressions to enforce… Read more »
Just read about Justniffer on UbuntuGeek and decided to give it a whirl. Downloaded deb installer from SourceForge and ran with: justniffer -i eth0 I received the following output showing a few web connections and a telnet session to a mail server. 192.168.1.100 – – [27/Oct/2010:21:33:52 +0100] “GET /wikipedia/en/b/bc/Meta-logo-35px.png HTTP/1.1” 200 1611 “http://en.wikipedia.org/wiki/Main_Page” “Mozilla/5.0 (X11; U; Linux… Read more »
This is my summary of Yum repositories for future reference. Yum (and apt on Debian systems) is an easy way to install software on Red Hat/CentOS systems and to keep those systems up-to-date. There are a variety of repositories with different software packages available which is why I like to use most of the following… Read more »
