I have recently installed few packages for telnet, mysql and postgreSQL. I can access all these service locally on the ubuntu server but somehow I am not able to access these services from other machines. Below are the active internet connections using:
sudo netstat -tulpn tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN 18776/inetd tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 19451/mysqld tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 8453/postgres
I am not able to figure out what I am missing. I am almost sure that I have configured these packages correctly to allow outside world connections.
When I am trying telnet from windows, I got "Could not open connection to the host, on port 23: Connect failed"
I doubt, my router might have blocked these connections but I don't know how to troubleshoot or unblock these connections. Please suggest, Many thanks!
