I'm using openssh on Solaris 7 (Intel):
% uname -X
System = SunOS
Release = 5.7
KernelID = Generic_106542-27
% ssh -V
OpenSSH_3.7.1p1, SSH protocols 1.5/2.0, OpenSSL 0.9.7b 10 Apr 2003
This morning I was trying to make a connection using ssh. The ssh
program would just sit there doing nothing. I tried ssh with the -v
option, which showed me that the program wasn't getting very far before
it would hang:
% ssh -v username@hostname
OpenSSH_3.7.1p1, SSH protocols 1.5/2.0, OpenSSL 0.9.7b 10 Apr
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 28: Deprecated option
It did the same thing no matter what account I was using or what system
I was trying to connect to (including making a connection back to the
local host). In contrast, telnet worked fine. I tried sending a hangup
signal to the sshd process (the one with ppid=1) but that didn't work.
Finally, I stopped and restarted the daemon using /etc/init.d/openssh:
That fixed the problem.
I've been using openssh on our development/test servers for several
months. I've only run into this issue twice. But both instances occurred
recently within a day of building the server.
Does anyone know what might be going on?
