ssh connectivity

[henry7849]

I'm trying to connect to my home pc with ssh.
I have road runner connected to a wireless router
and then my pc connects to the router via a wireless card.
I can use the Internet from my pc.
I also know sshd is running.
I do a ifconfig to get the ip address.
Then, nothing happens when I try to connect to this
ip address via ssh from a remote pc.
So, what's going on with this? How can I get ssh
to connect to the home pc?

thank you,
Henry

Hi Henry!

Sounds to me that you need to forward port 22 from your router to your home machine. Look in "port forwarding" in your router and have port 22 configured to be forwarded to the Internal IP address of your home box... that is the same IP address your box gives you when you do ifconfig.

Are you running this box dhcp (asking the router for an IP) or static (the machine tells the router what IP it is to have)? Obviously static is the best way to go inside your network. If trying to connect from outside your network, static is the way to go too as ISPs IP to you will change over time.

Once port 22 is forwarded to the desired box, contact your network using the IP address assigned to you by your ISP. A quick way to find this out is to go to What Is My IP Address - Shows Your IP Address. Let's say your whatismyip address is given as: 123.45.67.8 and your username on the home ssh server is henry. From outside your network you'd do:

ssh henry@123.45.67.8

The router will forward the request to the IP of the designated box and it will ask for your password.

I'm not sure I understood the exact procedure for dhcp on fedora. I looked up PF on Internet
and I found the followed (but it does not seem to work):
Would you know how to fix this?

I haven't used Fedora in a while so if you really do need to open port 22 on that box (and now I seem to remember that you indeed have to), the easiest way is to do it through it's utilities. From the command line:

su -

input password, then:

system-config-firewall

Or find it in administrative utilities. It should be intuitive enough to get you through opening port 22 on the box itself. If you need more, have a look at this page.
