I have Problem In me server *NETWORK*
Hi, i have a Pentium 4, exactly the same as the CPU in the picture
http://i39.tinypic.com/sb7sed.jpg and sometimes my network go down without reason, at least i don't know why. I know that sometimes it go down because my ping test fails replying Ping request time out. But is just sometimes and then a few seconds it come up again.... in that server is running a PBX service and the OS running there is Fedora Core 8. Everything is running well excluding the network device (the network device is integrated in the motherboard) What you recommend me? When i run lspci in the command line i get this output Code:
[root@TornadoR3 ~]# lspci -m |
Quote:
show packet counters on said network device Code:
Code:
mii-tool -v or if your device does not support MII, use ethtool Code:
ethtool <ethX> show some logs |
RE:
Hi, look i recently execute this
vi /var/log/messages and i read something like i ave to install nss-mdn so i download the nss-mdn RPM file... Now i proceed to execute each command you said... ifconfig output: Code:
[root@TornadoR3 ~]# ifconfig mii-tool -v Code:
[root@TornadoR3 ~]# mii-tool -v ethtool eth1 Code:
[root@TornadoR3 ~]# ethtool eth1 |

i dont think nss has anything to do with the problem. i think you will have to use normal network troubleshooting techniques from a remote host or another host on the network .. any of ping traceroute netstat mtr might help you find the problem. also tail the message log file. and check dmesg too. Code:
Code:
dmesg |
RE:
Look, before i install nss-mdn in /var/log/messages the file content has this lines
May 17 19:54:50 TornadoR3 avahi-daemon[2084]: avahi-daemon 0.6.21 starting up. May 17 19:54:50 TornadoR3 avahi-daemon[2084]: WARNING: No NSS support for mDNS detected, consider installing nss-mdns! May 17 19:54:50 TornadoR3 avahi-daemon[2084]: Successfully called chroot(). Now before installed the nss-mdn RPM file hte /var/log/messages have this line May 17 19:54:50 TornadoR3 avahi-daemon[2084]: avahi-daemon 0.6.21 starting up. May 17 19:54:50 TornadoR3 avahi-daemon[2084]: Successfully called chroot(). Look that the line May 17 19:54:50 TornadoR3 avahi-daemon[2084]: WARNING: No NSS support for mDNS detected, consider installing nss-mdns! Is not present... and now the ping test don't fail... What you think, is this the nss-mdn the Solution or is just coincidence? |

are the pings still failing?? mdns uses multicast to find hosts on a small network, so it could have been the problem,but the question is - is ping working ok now? |
RE:
Yes, for now the ping test doesn't fail anymore.
But i will still testing using more ping tests to be sure that that was the solution to the problem. Thanks, buddy if me problem still there, i will write to contact you again :D. |
RE:
Sorry, I still have the same problem
i make ping for some hours and Of 8247 sent packages just 8084 was received. Please, what can i do? In this cpu is running a PBX system and the calls sometimes are dropped by this. |
