Code Review: Checking open ports.by Chady (Priest)
|on Jun 09, 2003 at 08:12 UTC||Need Help??|
Chady has asked for the
wisdom of the Perl Monks concerning the following question:
I'm writing a small utility to monitor certain services on a dozen servers or so. I shouldn't have access on these servers, so I decided for the POP, SMTP and FTP monitoring to just check if their ports are open, since I wouldn't have access to check a logon.
I wrote this snippet:
Since I have a fairly small knowledge in networking, I was wondering if this approach is reasonable; Is there another way to check if the services are up without having to get a username/password and try a real login?
He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.
