There is a way to access sorceforge and never receive an IOException : use the following pserver details : Server : cvs-pserver.sourceforge.net Port : 443 This was mentioned on the sf site somewhere in regards to getting access to cvs from behind a firewall. Since I have changed over to this server/port, I havn't had any problems with access. Cameron Matthew E. Porter wrote: > You are welcome.
