following on from Sean's comment I have installed telnet and run the
command suggested above. On both benden & landing it hangs at this
point:
SSH-2.0-OpenSSH_5.1p1 Debian-5
(it is OpenSSH_5.3p1 Debian-1 on benden)
but eventually get "Connection closed by foreign host"
if I try "telnet landing 22" from benden I connect OK
but if I try "telnet benden 22" from landing I get
trying 192.168.1.6...
and then it hangs
until
telnet: Unable to connect to remote host: Connection timed out
looking at /etc/services it has two lines
ssh 22/tcp # SSH Remote Login Protocol
ssh 22/udp
/etc/ssh/sshd.config has a line
Port 22
so is there something else blocking off port 22?
