Problem with ping and printers

Postby majed » Wed Sep 27, 2017 9:57 am

Peace,
Recently, I added the printers to nagios and this started appearing:
PING WARNING - DUPLICATES FOUND! Packet loss = 7%, RTA = 158.15 ms
the nagios server has only one card, and i tried clearing the arp cache and setting the speed on the printers to 100 full duplex.
what else is it about?

This actually seems like a networking/network card problem and not a Nagios problem.

If you ping the device from the command line do you see items like this (DUP!)
Code: Select all
# ping 10.10.1.23
64 bytes from 10.10.1.23: icmp_seq=564 ttl=64 time=0.440 ms
64 bytes from 10.10.1.23: icmp_seq=565 ttl=64 time=0.441 ms
64 bytes from 10.10.1.23: icmp_seq=566 ttl=64 time=0.445 ms
64 bytes from 10.10.1.23: icmp_seq=566 ttl=64 time=0.458 ms (DUP!)
64 bytes from 10.10.1.23: icmp_seq=567 ttl=64 time=0.474 ms
64 bytes from 10.10.1.23: icmp_seq=568 ttl=64 time=0.470 ms

i know it is a network problem, but since you get frequent posts like these thought you might know. i tried setting the speed to 100 full duplex and 10 full duplex on the printers and the switch but the problem remains. this is only happening with the HP Pro400 MFP M425dn model, and only on certain vlans. i tried clearing the arp on the router nearest to the printers and the firewall connected to the nagios, but it didn't help. seems to me like it is a problem with the network cards of the printers, do you agree? or is there anything else to try?

Being as this is not a Nagios issue, I'll ask that it be posted in a support forum dedicated to general tech support, like this one: http://www.techsupportforum.com/forums/f31/

The link is to a section of the forum specifically for networking issues.
