> Hello, my son would like to do file xfer with a friend using ICQ. How would I go about configuring that?
For this sort of activity (as well as voice calls, and chatting), ICQ needs to open in-bound ports, which are nomrally blocked by the firewall. If you trust your internal users, and the ICQ software, you can enable these functions by running a proxy server on the firewall, and configuring ICQ to use the proxy for connections. There is a socks-5 proxy on the Dachstein CD, which IIRC is setup to allow unrestricted proxy access to the internal network, and no proxy access to the external network. The last bit is important, as spammers and other 'net low-lifes have begun harvesting "open proxies", which basically allow them to hide their identity w/o even the effort of installing malware on your machine. There are instructions on the ICQ site for setting it up to use a proxy. NOTES: It is very important you actually tell ICQ to use the proxy...otherwise, you'll still be able to connect to the ICQ server, but chat and file xfer will still not work. If you are *NOT* running a proxy, it is also important to tell ICQ it is behind a firewall. That way, ICQ doesn't try to open inbound ports (which it can't), and correctly negotiate a connection when one end is behind a firewall but the other end isn't (ie simply telling ICQ it's behind a firewall may solve your son's problems, if his friends don't have a firewall in place. If there's a firewall on both ends, at least one end needs to be running a proxy).
