Hi,
I am using Check_smtp to check mail service.
Anyone knows how check_smtp works?
When I use the internal IP address, I get 0 sec response, which returns
a critical warning in the web.
./check_smtp -H 192.168.250.10 -t 4
SMTP OK - 0 second response time
Socket timeout after 4 seconds
But when I use external IP address, it is ok.
./check_smtp -H 202.61.212.25 -v
SMTP OK - 0 sec. response time, 220 itumailsrv.itu.local Microsoft ESMTP
MAIL Service, Version: 6.0.3790.0 ready at Thu, 23 Dec 2004 15:03:51
+1100
I dont know what is socket timeout means?
If I use telnet 192.168.250.10 25, I can see the smtp service is ready.
And I can ping 192.168.250.10 without problem.
Can anybody explaain it to me?
Thanks a lot,
Lydia
