ssh server connect to host xxx port 22: Connection timed out on linux-ubuntu

Question

I am trying to connect to remote server via ssh but getting connection timeout.

I ran the following command

ssh [email protected]

and getting following result

ssh: connect to host [email protected] port 22: Connection timed out

but if try to connect on another remote server then I can login successfully.

So I think there is no problem in ssh and other person try to login with same login and password he can successfully login to server.

Please help me
Thanks.

Here are a couple of things that could be preventing you from connecting to your Linode instance:

1. DNS problem: if the computer that you're using to connect to your remote server isn't resolving test.kameronderdehamer.nl properly then you won't be able to reach your host. Try to connect using the public IP address assigned to your Linode and see if it works (e.g. ssh [email protected]). If you can connect using the public IP but not using the hostname that would confirm that you're having some problem with domain name resolution.

2. Network issues: there might be some network issues preventing you from establishing a connection to your server. For example, there may be a misconfigured router in the path between you and your host, or you may be experiencing packet loss. While this is not frequent, it has happenned to me several times with Linode and can be very annoying. It could be a good idea to check this just in case. You can have a look at Diagnosing network issues with MTR (from the Linode library).
