I have problem to access some sites but not all, but I have internet connectivity normally.
Example this site below cannot be accessed:
https://www.linode.com/community/qu...telnet-on-localhost-25-how-do-i-fix-it-solved
I get the following message in Mozilla;
Also, I was wondering if I am only using ip version 6 and this is the problem.
I am also unable to telnet to localhost 127.0.0.1 but I can ssh.
Also, I am programming a small client server application. The server is listening fine but the client cannot connect to this server on the same machine getting connection refused, while the client can connect and get out from any internet time server.
Relevant outputs below:
But the server is listening below....
But ssh works fine....
