I am having an unusual issue. I hope someone may have some insight for me.
I have 3 computers. Lets call them home, work and server.
When connecting through ssh I can connect:
- from home to server
- from server to work
- from home to server to work
but when I try to connect from home to work I get:
Also when I nmap from home to work I get:
ssh: connect to host ems4.rrc.uic.edu port 22: Connection refused
though from server (or home to server) to work I get:
Starting Nmap 4.53 ( http://insecure.org ) at 2008-06-24 21:48 CDT
All 1714 scanned ports on work.workserver.com (***.***.***.***) are closed
Nmap done: 1 IP address (1 host up) scanned in 0.235 seconds
I wonder if this is due to the ssl key stuff, but then why could I go from home to server but not home to work. And besides nmap comes up empty too which would not have anything to do with ssl. So perhaps I am off base there.
Starting Nmap 4.53 ( http://insecure.org ) at 2008-06-24 21:51 CDT
Interesting ports on work.workserver.com (***.***.***.***):
Not shown: 1707 closed ports
PORT STATE SERVICE
22/tcp open ssh
111/tcp open rpcbind
113/tcp open auth
631/tcp open ipp
1234/tcp open hotline
5900/tcp open vnc
8000/tcp open http-alt
Nmap done: 1 IP address (1 host up) scanned in 0.129 seconds
As a note all comps are running Ubuntu 8.04 and are regularly updated, the server does not run X.
Thanks for any help
