[suse-security] SSH Failure: No route to host

[Dimitris Stasinopoulos <dsta@xxxxxxxx>]

Hello everyone,

I recently installed SuSE 10 Professional (updating from 9.1 - erase and 
install) on one of my servers. My server has 2 interfaces, external and 
internal. Among other services, I installed ssh. While I can ssh to the 
server from the internal network, I can't from the external:

reverant@Liberty:~> ssh -l reverant -C my.i.p.addr
ssh: connect to host my.i.p.addr port 22: No route to host

I can telnet to other services (ie. httpd, sendmail, qpopper) just fine, so 
the error message would most likely be because of  the SuSE firewall. So I go 
in YaST, and add "SSH" to the allowed services in the external interface, 
restart the firewall but still no go. I completely disable the firewall, and 
still nothing.

The previous (9.1) configuration worked fine (SSH-wise), so the likelyhood 
that something else (ie external firewall) is blocking the ssh attempts is 
propably out of the question.

Any ides here? Thanks in advance,

Dimitris
