Hello all

We are trying to implement PacketFence on our network with the sole purpose of blocking Windows XP (a full implementation needs to wait).

set up a Linux Server with all the necessary services running.
created the VLANS as requested
set up a Cisco 3560 switch on PF for production
have a station connected to that switch and PF does put in the ISOLATION vlan.

When I tried to add a violation to include Windows XP (OS Class 100) the option was not available on the dropdown menu options, how do you add it in order to create the violation?

Thanks in advance

trying to see the support archive can sieve any thing close to your encounter and there is one close though it is trying to detect AP but it used the "trigger" such as "trigger=OS::4" and customised a violation id via the violations.conf. maybe can find this file and see if the violation id has any on Windows XP....

e.g. http://sourceforge.net/p/packetfence/mailman/message/27993414/

PacketFence policy violations are controlled using the /usr/local/pf/conf/violations.conf
configuration file. There is a "trigger" field, formatted as type::ID. The type can be Detect (Snort), Nessus, OpenVAS, OS (DHCP Fingerprint Detection), UserAgent (Browser signature), VendorMAC (MAC address class), SoH (Statement of Health filter), Accounting, etc.

I did a search in the archive on DHCP OS fingerprint but did not managed to sieve through all though so maybe you can catch it too

http://sourceforge.net/p/packetfence/mailman/search/?q=DHCP+OS+fingerprint

Others...

Here is an old article using command  /usr/local/pf/bin/pfcmd report os and the system will return the os in the network monitor. If window xp is identified then the box should be functioning as it is.

http://www.techrepublic.com/article/solutionbase-use-packetfence-to-stop-unwanted-network-traffic/

The /usr/local/pf/bin/pfcmd config help is suppose to let you see a list of all the types of help you can get. Help topics include: control, service, version, person, history, node, violation, report, fingerprint, lookup, graph, config, ui, class, trigger, update, and reload.

Admin guide has info on the violation.id and more as well on the various fields - http://www.packetfence.org/downloads/PacketFence/doc/PacketFence_Administration_Guide-4.1.0.pdf
