Hi All,

I have a server that I'm using as a Git repository. I'm trying to clone from this repository to a GoDaddy server. I am getting the error "ssh: connect to host <my git server ip and port>: connection refused.

I have checked the ssh_configs, sshd running, rsa keys, openssh-server/client, some stuff I forget, ...

I haven't been able to fix the problem or google anything that has moved the issue along.

I would talk to the kind folks at GoDaddy about this but the last two times I've called up I end up giving them technical support (and bearing in mind I know very little about servers and such, this is very disheartening).

Any help, advice or nudges in the right direction would be greatly appreciated.

Hi Tinnin,
Have you been able to log in to the server from another location before? If not, please check your firewall settings on the server, IPTables maybe? Please also advise on what distro of Linux you are running on that server.

If you can, post the contents of /etc/ssh/sshd_config here.

You could change the port to something other than 22 (which could be blocked by some firewall) and see if that works (when you change the port, you have to specify it when trying to connect to it).

Hi guys.

Sorry about my late reply to your answers. Busy busy.

So this is my current setup (not changed since before my opening post).

I think this is what came with the NOOBS setup of the raspberry pi model B.

iptables -L:

Chain INPUT (policy ACCEPT)

Chain FORWARD (policy ACCEPT)

A bit more info:
I've set up port forwarding for my router to the git server local ip ssh port.

When I run PFPortChecker to test for the connection I get a result of "Your port is OPEN on another device"

I assume this is why I can't connect from the GoDaddy side of things.

Is this something a can resolve on my git server or is it a problem elsewhere?

It's probably not a good idea to use port 123, because that's the standard port for the network time protocol (NTP). It is likely to be in conflict with it.

When you need to pick an arbitrary port number for something like this, you should always pick something much higher (never below 1500, because most of those are reserved for standard protocols).

A typical port used for ssh, besides the standard 22 port, is the port 22022. In any case, try using a much bigger port number to stay clear of any standard protocol.

I see. I set it back to port 22 for the time being but the issue persists. I'll try your suggestion of making it a high number.

I've changed the port forwarding public port to 55555. This points to port 22 on my local server.
I've followed the instructions here to disable any firewall settings. Though I'm not sure how necessary that was as there was nothing there to begin with anyway.

I tried to generate a key on the remote server and ssh-copy-id it to my local server but it still came up with connection refused.

It seems that attempting to connect via ssh through the dynamic dns using port forwarding, I get the "connection refused" message, yet I can connect locally via ssh through the local ip and port.

What could it be that I'm cocking up?

I found out that logs of ssh connections are kept in /var/log/syslog

I've been getting the response:

ddclient[2163]: WARNING: cannot connect to myip.dnsdynamic.com:80 socket: IO::Socket::INET: Bad hostname 'myip.dnsdynamic.com'

which comes from /etc/ddclient.conf which I set up using this guide when I set up a dynamic dns using dnsdynamic.

Any ideas on what I should be changing the line,

use=web, web=myip.dnsdynamic.com   # get ip from server.
