Can't SSH Rasp Pi remotely?

[JackDooner]

Hi, I have 2 Raspberry Pi's, both connected via Ethernet with static IP addressed.

I've assigned custom SSH ports for both. (2201 & 2202)

On my first Pi, I have no issues. I can SSH inside or outside my network. Perfect.

But on the other, I have issues from outside my network.

Everything is set up the exact same way (Port Forwarding etc...) and I have extensive experience in networking, so I know what I am doing. How ever I am left scratching my head.

Can anyone suggest further troubleshooting?

From the problematic Pi, I have full internet access. I can ping everything with no problems.

Thanks in advance.

Run tcpdump on both Pis and observe what happens when you try to connect (i.e. do the packets make it as far as the Pi, do they have a funny address? does the Pi know how to route replies?)

Check if sshd is running and listening on the right port:

Code: Select all

$ sudo netstat -tlpn

Check the log. Raise the log level of the second pi ssd server to DEBUG or DEBUG2. Server side /etc/ssh/sshd_config:

Code: Select all

# Logging
SyslogFacility AUTH
LogLevel DEBUG2

restart sshd:

Code: Select all

$ sudo  /etc/init.d/ssh restart (or reload)

From the client side, login with the highest verbose available.

Code: Select all

$ ssh -vvv <target_address>
