i just went thru the forum listings with the same problem. but mine seems a little different.
i'm working on linux.i use :ext: method to connect from IDEA(2.6).[:ext:@:/usr/local/cvsroot]
i used ssh-keygen -t rsa and generated a public key which i posted on the server.
i set the CVS_RSH=/usr/bin/ssh and i set the CVSROOT too.
from a terminal i'm able to execute all my cvs commands without typing a password. but from IDEA, cvs doesnt seem to work. this is the output i get in the console
/usr/bin/cvs status ]]>
cvs : connect to (]]>):2401 failed: Connection timed out
CVS command finished execution
port 2401 is disabled on our server. and i cant figure out how it gets this port value.
