CHECK_NRPE: Socket timeout after 10 seconds

[lmiltchev]

Do you have a IPv4 address assigned to eth0 on the client? Check it out by running:

Code: Select all

ifconfig

[dbarnsdal]

[root@detvmrh2 ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:50:56:9E:3D:88

QUITTING!

[root@detvmrh2 ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:50:56:9E:3D:88

Is 158.60.140.211 you nagios server, or remote host?

[dbarnsdal]

detvmrh2 140.211 is the client.

[lmiltchev]

Can you restart the network on the client?

Code: Select all

service network restart

...and check the IP again?

Code: Select all

ifconfig

Then from the nagios server, run:

Code: Select all

nmap <remote ip address>

and show the output.

Hi guys.

I believe I've discovered the issue. There isn't a software firewall, there is a physical firewall between the two subnets.

Thanks for all your help.

Yea, that would do it. Locking the thread up now, feel free to post another if you need to.
