Hi small_student,

I'd like to set up all those options. So I don't need to install OpenSSH as bobalob suggested?

I tried to connect via my vista using PUTTY to my home server and it states network error:connection refused. I'm behind a router (Linksys WRV200).

What do I need to open in my router or is there some setting that I need to change on my centos?

Thanks, Victor

I still get that same error.I'm thinking that I had to update my dns recently via dyndns. It shouldn't take long to propogate, right?

I put my ip address in there.

oddly enough I can't get my httpd to start. Are you sure that I shouldn't be opening something on the router?

No I just tried using putty from my windows vista. It's on the same lan. I assume that isn't the problem (being on the same lan - that is).

when I telnet 192.168.1.106 22 on my vista I get:
SSH-2.0-OpenSSH_4.3

so it looks like it's working.

Yup that means that it is working. Ok then when you use putty what do your get, post a screen shot of the error please

That seems to work with 192.168.1.106.

I tried logging in with my username vkimura and the password that I login to the computer but it's denying me to get in.

That other ip was obtained by searching for what's my ip on the WAN.

ASKER

Oh, I had to use root as the username.

But I want someone from outside my lan to putty into my machine.

Do i set that up in port forwarding or port triggering or both on my router. I get those two mixed up. I know the router has NAT. Is there a way to confirm this is working:
publicIPOfRouter:Port22--->192.168.1.106:22

ASKER

Can you please show me how to:
If you are looking for fine tunning your configuration then there are many things you can do

1- Prevent root logins and login with a normal user then su - to become root
2- Change the port you connect to SSH
3- Disable passwrods and create key based authintication
4- Allow only certain users to have access to SSH

Much thanks. I really appreciate your help. =)
