I want to ssh to a RedHat server running OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003 The server hosts several websites.
I have used three machines all from behind the same NAT 1) Debian unstable 4.6p1 OpenSSL 0.9.8e 2) Ubuntu 7.04: ssh -v = OpenSSH_4.3p2 Debian-8ubuntu1, OpenSSL 0.9.8c 05 Sep 2006 3) Mac OS X The error log is below. The session hangs. Ctrl-C does not recover, I have to kill the terminal window. Note that a Windows machine running Putty succeeds, and on all machines above, a Java ssh client succeeds. The problem exists on two accounts on the server. I can also duplicate the problem communicating the other way. That is, on my home network I installed sshd on the Debian machine. Then using the java ssh client, I shell in to the Red Hat remote machine. From the shell, I use ssh to try to connect back to the Debian server at home. The log is the same. Password authentication succeeds, but the sessions hangs with the same final output from ssh -vvv Meanwhile, I have a friend also using Debian who can shell into the webserver machine. So there is something about my network at home that kills multiple versions of openssh but which does not affect other ssh clients. I have a d-link router which acts as a firewall and NAT. using env -i ssh ... makes no difference to the result. The log file is very similar for all three configurations.
