Author: john lewis Date: To: hampshire Subject: [Hampshire] unable to connect from one system to another using ssh
I have two Debian systems, benden and landing, landing normally has
no screen attached so have been using "ssh landing" for months to do
system admin stuff on that box with no problems.
I know want to run unison on landing to synchronise the geneweb
directory on landing with a geneweb directory on benden and for this I
need to be able to setup ssh on landing to allow "ssh benden"
But I get an error message
ssh: connect to host benden port 22: Connection timed out
so far as I can see ssh & sshd on landing is set up in exactly the same
way as on benden with one exception, ~/.ssh/known_hosts on landing is
an empty file.
I generated the keys on landing without a passphrase, I don't remember
if I did so on benden as it was many moons ago. I can ssh to landing
without being asked for a password.
"ssh -vvv benden" produces a small amount of output but terminates with
the same timeout message
I tried "ssh startx.co.uk" which resulting in getting the key
fingerprint for that server being added to the known_hosts lists.
"ssh landing" from my EeePC works (asking for a password) but "ssh
benden" also times out.
Which suggests the problem is only with ssh into benden, but am at a
loss as to what the problem actually is.
