I use cygwin 1.3.12-2 on Win2k, `ssh -V`="OpenSSH_3.4p1, SSH protocols 1.5/2.0, OpenSSL 0x0090604f". I tried to connect to a RedHat Linux 7.3, `uname -a`="Linux floodgate.internal.net 2.4.18-3 #1 Thu Apr 18 07:31:07 EDT 2002 i586 unknown" using "ssh -2 -X floodgate.internal.net". Ctrl-C is passed through with no problems to the bash prompt, as well as to cat and ls. - Which OS are you running under? - Exactly which commands are you using to connect to the linux server? - Does this problem occur when connecting to other (linux and non-linux) servers? - In what situation did Ctrl-C terminate your session? - Are you using authorized_keys, or some such mechanism? - Is your X server started at the time when this problem occurs? - What do you use to run ssh (i.e., command prompt, bash window, rxvt, xterm, other)? - Does it occur when connecting to the cygwin sshd on localhost (ok, ok, maybe that last one's too much to ask unless you're already running sshd).
