Check the first time you install Linux OS

am3n — Wed, 26 May 2010 16:40:37 +0000

If you forgot when you deploying (installing) a server (or Desktop) with Linux OS (esp. RedHat and its derivatives) you can check date of first file created after successful installation. You need root privileges to check the file.

- Login as root, then
- type “ls -l anaconda-ks.cfg” and hit Enter

[root@patrick ~]# ls -l anaconda-ks.cfg
-rw-r--r--  1 root root 1483 Aug  6  2005 anaconda-ks.cfg

So the first time I installed Linux on that server is 6 Aug 2005, if I haven’t reinstalled the OS, then that date will be also the date for the hardware is being use for the first time also. Now after 5 happy years running 24/7. Isn’t about time to replace the hardware with the new and faster one?

Proxy Server using Squid, DansGuardian and ClamAV

am3n — Fri, 14 Nov 2008 16:14:47 +0000

I was going to use “Proxy Server using CentOS 4.6 and Squid+Adzapper and DansGuardian+ClamAV” for title but that to long .

My current proxy server was a left over from the previous SysAdmin, and I never touch nor fix it, coz it aint broked . But after several monitoring, the use of Internet from users is getting high, virus risk, and they no longer productive (actually for the last I dont care as I am not their employer)

This new proxy it has ability to
• Scan all traffic for virus
• Zap/remove ads/banner
• Content filtering based on naughtyness level and sites category
• ACL based on IP Address

The Complete step by step installation is attached below:
Proxy Server Installation manual

Next phase will have: (after using CensorNet)

Access list based on username (same as email account)
Bandwidth priority, policy and scheduling based on user group
Utilize Watchguard’s Web-blocker addon
