We use Jabber as the IM server running on Solaris and Exodus as the client running on Windows. I'm sure Linux or any other similar platform could be used for the server. Both Jabber and Exodus are opensource projects (see www.jabber.org). There are public Jabber servers and I don't know if you could prevent a clever employee from connecting to one. Probably blocking the port used at your firewall would stop all but the most determined employee (see below). > How can you manage/control Instant messaging to professional/work > related use to prevent abusing it by having employees sending jokes > to each other all day? I'd say by establishing a policy that says Instant Messaging is to be used for professional/work related use only. I'm sure you already have a similar policy for email and a similar policy for browsing. Enforcement of all three policies is the hard part. If you have employees who are spending too much time sending jokes, trying to work around company firewalls, etc. then you you have a bigger problem than just installing and locking down an internal use only IM system. The reason we installed a company private IM system was to allow company confidential conversations. With a public server, you don't know who might be listening or logging all of your IM conversations. We use SSL to allow our off site employees secure access to our IM server.
