[QUOTE=LayTech;4042510]Okay. I got this:
Connected to 172.20.130.71.
Escape character is '^]'.
Nothing came out after the third sentence.
Good, this mean that's working.
Now, what does this command give you:
/usr/local/nagios/libexec/check_nt -H 172.20.130.71 -p 12489 -v MEMUSE
for your firewall, make sure that the IP address of your nagios is allow to comunicate with your XP machine on ports that the services you want to check are running:
FTP: (default 21)
SMTP: (default 25)
When your firewall is setup, try this again:
/usr/local/nagios/libexec/check_ftp -H 172.20.130.71 -p 21 -w 10 -c 20
PS: Don't forget to post the output of these commands as it is.
