Hi

I run Red Hat 7.3 box. I use LinkSys DSL router MODEL: BEFSR41.
So I want to enable the ssh connection to the box using port 22.

In order to do that, I need to make changes to the FORWARDING option in LinkSYS

So I did:

#1 htp://192.168.1.1 // login
#2 click Advance
#3 click Forwarding
#4 Enter Port 22 on Service Port Range, looks Like
Service Port Rande 0 ~ 22 IP Address 192.168.1.1
#5 Click APPLY

However, when I try connect remotely to the box it can't connect..
I typed the command to connect: ssh -l my_Ip_address

It doesn't work ..

Can someone give me a hint on that?

Thanks

M.S.

You're not indicating that you forwarded ports 0 through 22 are you? That won't keep SSH from working but it's more ports than you need, you can do just 22 - 22. On newer Linksys firmware make sure there is a checkmark in the "enable" box at the right. Also make sure you've chosen protocol TCP, not UDP. Last but not least, a -l parameter specifies what username to ssh as in case it's different than what you're logged in as now.

Firewall rule blocking you? Try "ipchains -L" and "iptables -L" to list current rules.

Good luck!

I don't have firewall ..
So in order to connect remotely to the server I need to do the following:

ssh -l username remote_IP_number
Correct?

Thanks

Yes.. or just "ssh ip_number" if the user you're currently logged in as is the one you want to log in remotely with.

Thanks wdingus

Another question:

If I run the box and currently login as username: mike .. Can someone remotely login to the box with the same username?

Thanks a lot

M.S.

Not sure I understand.. If someone else knows the password for that account, sure they can login. If you forward the port int he Linksys then anyone can connect to it. The thing to do is to keep the password secure and keep the version of SSH up to date (security patches, etc...).

Most likely this didn't work for you cause you would want to put that in this format:

ssh username@host_or_ipnumber

When you made a space between the username and remote IP number, ssh thought most likely it was trying to connect to your username like if it was a host computer.

OpenSSH will take either "-l user hostname" or "user@hostname" as correct syntax.

mikeshn, your forwarding that to 192.168.1.1, which is the router's default IP. You have to forward it to the IP of the computer on your network that you want SSH to connect to.
