Hello,

I have seen that there are several Haskell libraries for cgi scripts and the like. Is there also a possibiliy to deal with sockets and firewalls?

Yes, there's the Sockets module in the ghc library, which allows you to do TCP and UDP (and more). I can show you some examples. Not sure what you mean about firewalls, there is nothing that I am aware of to do packet filtering and routing and the like. If you just want a socket connection across a firewall, I'd just tunnel it through ssh. --C.
