Hi!

We need more information.
- Could you provide the command you are issuing?
- Have you checked that port 22 is indeed open?
- Have you tried nmap on the server you are trying to connect to?

Best regards,
HMW

Hi, Thanks for reply. yes port 22 is open have confirmed. Actually the VPN connection to a site is giving error code is 0. I actually require the VPN tunnel to be working first and after that I should be able to connect to any router but the VPN tunnel is giving that error message 'please check your input.

The vpn client stopped, error code is 0'

Command for SSH is 'ssh -l xxxxx@0.0.0.0' example

The error is connection "refused" , it means the connection was actively refused by the ssh server.

If the port wasnt open you would probably had a connection timeout.

refused can mean :

-> invalid username password combination
-> password / username expired
-> your IP / account has been banned/blocked.

It maybe the way you have -l that is throwing things off. The right syntax would be either

Code:

ssh -l xxxxx 0.0.0.0

or

Code:

ssh xxxxx@0.0.0.0

Where xxxxx is a valid user name and 0.0.0.0 is substituted for a valid host name or ip address.

Turbocapiltilist, yes I also tried to change to the way you mention. Unfortunately still gives that same error code. Funny thing is the vpn tunnel was working few hours back but just now getting this error

Sorry misspelled your name

Turbocapitalist · 05-20-2016, 12:34 PM

No worries.

Can you use a telnet client to check port 22? It won't get past the identification, but that will be enough to verify that you should be getting through to the SSH server.

Code:

telnet server.example.com 22

It should say something about SSH-2.0 and then the version of the SSH server.

Or SSH server not running, or using a different port

It's strange. Good news is the vpn tunnel is working connection established now just the issue with ssh into a router, not responding. I could ping the dns server and got packets back

Had this in the past, in my case it was a firewall issue.
Rectified as root using the command ufw allow ssh

Dennis99 did you enter that command in root/vpn or just in root@xxxxxx
