Hello All.

I am messing with the new CentOS7. Installed it fresh last night from the "Everything" ISO. Also created an image last night of the fresh install so don't worry too much about mucking anything up.

I am having a problem SSH'ing into the box via remote system. Local systems on the same LAN (such as my gaming box I am RD'd into now to SSH into my server) work. But the moment I attempt to connect via my work system I get a connection refused. I have checked the usual suspects such as firewalls and port forwarding. The port is open and directed to the correct pc. So I am thinking it is a configuration issue. I have looked over the sshd_config and I do not see anything preventing access though I could be mistaken.

Oh, and I am not looking for a whole lot of security on this system. This is a throw away install for me to test out CentOS7. Anything goes wrong I will just reimage and try again

EDIT: So I was attempting to port forward from #### to 22 using my router's NAT (I should have included that info. Did not realize it could be connected). My install did not like that and refused the connection. However, when I switched it back to 22 to 22 it worked just fine. So it is a setting I am just missing in the sshd_config.

I installed RHEL7 last week and SSH worked out of the box without modification to the sshd_config file. Did you make changes to it?

The things that come to mind from what you describe is the builtin software Firewall. Did you mark SSH as a trusted port in the current firewall? Also, is SSH running? I know in both cases, an LAN SSH would have failed, so I'm assuming/hoping there was a reboot between your LAN tests and your WAN attempts.

Is this running in a VM or is it on a real live PC? that could also make a difference in terms of routing...

It seems I have solved it (for now)

The edit in my above post shows that the issue was in fact my port forwarding in my router. A common practice I use is making the external facing port different from then internal. Here is an example using FTP (I do not have FTP installed or configured so these ports are bogus)

When I did this with ssh it did not like it and refused the connection. I have reversed this and now the outward facing port is the same as the internal and it works fine. I will have to go into the config and change it.

As far as VM/PC, this is running on hardware. No vm. And everything seems to be running fine now so I think it was just the NAT that caused the issue

I see. You should mark the post as solved. I think that is in Thread Tools > Mark as Solved or thereabouts..

Will do. Was just looking for the button. Thanks
