can't start sshd
Hi All,
For some reason, I am unable to start sshd. I have combed thhrough many
web pages and the archive, but did not find anything that sounded like
my specific problem. I even resorted to a fresh install of the most
recent version of ssh in unstable, but to no avail.
When I run /etc/init.d/ssh restart, I do not get any error messages, but
it does not start. When I do an ls on /var/run, there is no sshd.pid.
I am not entirely sure what I should check.
When I run sshd -d, I get the following output:
debug1: Seeding random number generator
debug1: sshd version OpenSSH_2.9p2
debug1: private host key: #0 type 0 RSA1
debug1: read PEM private key done: type RSA
debug1: private host key: #1 type 1 RSA
debug1: read PEM private key done: type DSA
debug1: private host key: #2 type 2 DSA
debug1: Bind to port 22 on 0.0.0.0.
Server listening on 0.0.0.0 port 22.
Generating 768 bit RSA key.
RSA key generation complete.
Below is the output from strace sshd:
