Hello,
I hate to bring up what is most likely a very simple question but I have spent a couple hours on this now and figured it was time to ask for help. I am for some reason unable to ssh into my arch box. It is a brand new installation, the only thing I have done is install lxde and openssh.
I have changed the port to 25522 and at the bottom of /etc/ssh/sshd_config I added AllowUsers <username> (which is my username) and PermitRootLogin no
I have a ddwrt router and I forwarded the port to the ip my arch box is running on. According to http://www.canyouseeme.org/
Error: I could not see your service on <IP Address> on port (25522)
Reason: Connection refused
Any idea why this is happening, or any additional information I can provide? I do not think it is the routers fault though because I get the same connection denied when trying to connect from another computer on the lan.
Thanks

You might want to remove your ip address and username from your post
Have you made sure that sshd is running after installing it? What is the output of
ps aux | grep sshd
If it doesn't show up, try starting the ssh daemon:
/etc/rc.d/sshd start
If it is running, check to see that it's listening on the port you specified:
nmap -p <your_port_here> 127.0.0.1

Good point, thanks

Is there a line in hosts allowing you access ssh?
sshd:192.1.1.1 # your remote box
Have you changed the line in ssh_config to use the port 25522 on (I think) the host [the new install].
What about if you try port 22 (the default)?
ssh -p 22 user@ip

Thanks for the response. It is running already and I have sshd added to the daemons that autostart.
I installed an ran nmap which tells me that the port is closed and the service is unknown. Why would a port be closed? Does Arch come with a firewall installed?

Arch closes all the ports by default. Can you post the output of cat /etc/hosts, cat /etc/ssh_config, cat /etc/sshd_config on the target box (and don't forget to omit sensitive data)
edit: It's good practice to restart the sshd daemon whenever you change a config file.

Alright I think I got all the sensitive info out. This is going to be a bit long

You need to uncomment the line in your sshd_config where you changed the port. And then restart the ssh daemon.

Haha well that is very embarrassing, can't believe I missed that. Thanks for you patience!
