Full Discussion: PING to AIX works but TELNET FTP SSH doesn't work
Operating Systems AIX PING to AIX works but TELNET FTP SSH doesn't work Post 303031696 by rbatte1 on Monday 4th of March 2019 12:23:05 PM

I would add:-
  • Possible router/firewall issues
  • Excessive server load (either CPU meaning it never fully connected or too much network traffic leaving it unable to respond)
  • DNS lookup failure, i.e. the DNS used by the server went off and the timeout was too long to allow the connection. The server will try to reverse lookup your connection for logging.
  • Client side issue perhaps?

It's all a bit vague so I can only be vague in suggestions.
