Monitoring remote hosts

[Daniel Wittenberg]

You might want to check:

 

netstat -nap |grep 5667

 

That will show you what's actually listening on that port, if anything.
That's usually oen big reason xinetd couldn't start up.  Like maybe you
have an RC script starting up NSCA outside of xinetd.

Hey daniel!

Wow, this really showed my error i think. I cant connect either on
localhost:5667 nor from the server via telnet 5667...
Could i ask you if you could walk me through how to troubleshoot this?
That would really make my day :)
yes, i use xinetd
this is the config file :

# description: NSCA (Nagios Service Check Acceptor)
service nsca
{
flags           = REUSE
type            = UNLISTED
port            = 5667
socket_type     = stream
wait            = no
user            = nagiosadmin
group           = nagios
server          = /usr/sbin/nsca
server_args     = -c /etc/nsca.cfg .inetd
log_on_failure  += USERID
disable         = no
only_from       = 127.0.0.1 *.*.*.*
}

im a total tool coming to this, what should i change? :)
