Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

this is my second Question on Server Fault.

Devices in hand:

  • Cent OS - 32bit (update)
  • Squid installed (not configured)
  • Sarg installed (not configured)

I'm looking for a solution to the following problem:

  • log all the LAN traffic on Squid. I need an option to block 200 web pages (in future)
  • Yahoo, Gtalk need to monitor the chat timings ( web-chat )
  • Yahoo, Gtalk, MSN Messenger, Pidgin need to monitor the chat times (through client)
  • need to generate the report each user name or each host name (IP addresses are assigned through DHCP 192.168.200.0/24 )
  • report should be done hourly, daily, weekly and monthly
  • separate report for chat sessions

Controls I have:

  • Domain admin access
  • root Access for Linux
  • Network devices (router and switch ) en config privileged access

Anything you want more kindly update.

Thanks in advance
Kartook

In germany, iirc, you aren't allowed to track any content that could be personal/private, if the employees didn't sign a "no private internet usage" form/term.

I'm just wondering why noone had any privacy/security concerns yet.

For IM you might use Imspector - goes a bit beyond what you want, but can easily log "chat volume". SmoothWall (Bias disclosure: I work for these guys) put it all together in one package - it will cost money, but save you a bunch of time. Imspector is maintained and part funded by SmoothWall.

i can't answer for all your request but i can tell you what i use and works magically:

"log all the LAN traffic on Squid. I need an option to block 200 web pages (in future)" -> I use a squid acl with the "dstdomain" directive to block a list of site in a text file. If you also need to block sites by categories, i suggest you to use the wonderfull Squidguard too with a blacklist database. I also use another url filter to complete which is provided by the free opendns.com services.

"need to generate the report each user name or each host name (IP addresses are assigned through DHCP 192.168.200.0/24 )" -> I tried SARG but it isn't maintained anymore and crash with huge log files, so i use FREE-SA which provides the same features and works very well (no database needed).

"report should be done hourly, daily, weekly and monthly" -> Use crontab to launch FREE-SA when you want

I hope this could help :)

PS: If you have an Active Directory domain, like me, you can also configure Squid to make your users transparently authenticate (SSO) with Kerberos and LDAP.

Not sure about the over all site monitoring, but as you try an monitor one chat system once people figure out you are they'll just move to another one. Or move to a secure one like skype you can't monitor. So I don't think that a battle you can win, from a monitoring standpoint.

Though you could do this.

Block all external access to IM services

Setup an IM server (like Microsoft OCS), have this IM server do federated connections to the other "approved" chat services, yahoo, google, AIM, MSN, etc. This means the all traffic is routed though the IM server under your control, so you can now have that IM server log it. I think OpenFire can do it too, but I haven't setup that one up in that mode. People can only use approved chat services now and its under your control.
