RE: hopster bypass that firewall!

["Hagen, Eric" <ehagen () DenverNewspaperAgency com>]

I would say that the best bet would be to block access at the firewwall to
Hopster's IP address(es).  Without having the program installed to watch the
traffic, I don't know what server it contacts, but I imagine it would
probably be a single domain which could be added to a firewall rule to
prevent the connection.  Since it likely uses common ports to transmit,
blocking the ports isn't going to work.  In fact, I believe Hopster is just
a simple frontend to a SOCKS5 proxy out on the Internet.

Has any one come across this app called hopster, 
from my reading it allows you to bypass the firewall
to get to the IM networks among other things.

Is there a workaround to block it from working Also is
anyone aware of other apps like it.

Thanx in adv.
