[mrtg] Re: SMTP on TCP port

[PAUL WILLIAMSON]

What exactly are you trying to do?  If testing, 
"pinging" the smtp is hardly reliable.  Often the smtp 
port will not respond to queries to the port, even 
though it is still able to process.  I think this has 
more to do with the nature of udp vs. the application 
not doing its job.  The best way to test smtp is to 
send messages through the smtp gateway and then check 
them with a pop3 or imap4 client automation of some 
kind.

Hi,

I was having immence problem binding net-snmp to a udp port, it just 
wouldn't go.  I tried evcerything I could think of, however it worked 
first time on TCP (so it wasn't the config file!).

I could properly walk it etc.

Therefore I thought that if MRTG could access TCP ports then it would 
mean that I didn't have to contine battleing against funny things that 
redhat has probably done to its system.

Cheers,

Chris
