unknown hostname
128.153.144.233 (i am sure it is correct) is the ip address of the machine i put red hat 9.0 on it. but i cannot ssh to. its saying host/servername not known. What should do
either your SSH Daemon isn't running on that machine or your firewall settings are blocking port 22.
I am going to assume this is a box on a cable modem. If this is the case you need a dynamic DNS client (www.dyndns.org) to one make the machine accessible from the Internet. Two as mentioned above by rindi you need to make sure if you have a router in front of the box that it allows SSH connections through from the Internet. Then you should be all set because all default SSH installs will allow connections from 0.0.0.0/24 (i.e anywhere). Hope this helps.

I need to ammend my above statement: "If this is the case you need a dynamic DNS client (www.dyndns.org) to one make the machine accessible from the Internet" It should read "If this is the case you need a dynamic DNS client (www.dyndns.org) to one make the machine accessible from the Internet by hostname otherwise you can continue to access by IP, provided your IP does not change.
