Somehow I have been charged with the task of organizing the installation of a new production environment involving 4 servers.
I have to make requests to the Network administrator to open up ports on the firewall. He says he has made the changes and I need to check them.
I need to check that:
1 server alpha will be able to SFTP to server beta.
2 server alpha will be able to connect to LDAP on server gamma 636.
3 server alpha will be able to view webservices on server delta port 80
The best way I know how to do this is to try to telnet to the server, so for example for situation #1 I tried logging into alpha and :
alpha> telnet beta.mycompany.com 22
Is there a better way to test if I can connect on ports 22, 636 and 80?
