Hardware or software problem ?

Distro: Slackware 9.1.0
Kernel: 2.4.22 (recompiled)
2x NIC 8139too (eth0 = Internet eth1 = LAN)
Destination: NAT server with DHCPd on eth1

The problem appeared yesterday. I have lost connection to Internet as well as users from LAN were not able to get local IP form DHCP (DHCPd listen on eth1). Users were able to get IP for 2-3 sec then lose it.

Finally I have solved problem by changing one of NICs and putting another to other PCI slot. Also found that one of users were connected with some PLANNET router - disconnected him.

Here is what I fouind in syslog and what I still dont know what does it mean:

Code:

Just in case here is my DHCPd conf. Wonder would it be problem that someone have another DHCP server on LAN - if Im right then how to make my server to be more authoritative ?

Code:

ddns-update-style none;
authoritative;

    subnet 192.168.1.0 netmask 255.255.255.0
  {
    default-lease-time 72000;
    max-lease-time 144000;
    option subnet-mask 255.255.255.0;
    option broadcast-address 192.168.1.255;
    option routers 192.168.1.1;
    option domain-name-servers 217.98.63.164, 194.204.159.1;
    option domain-name "local";
    range 192.168.1.21 192.168.1.254;
  }

Well the kernel errors would indicate, and changing the hardware would confirm, that there was a problem with that particular NIC (or perhaps that PCI slot itself, since you changed slots and cards).

czezz · 04-18-2008, 09:33 AM

well... im not 100% sure because after I changed slots and one of NIC errors still appeared.
It stopped after I disconnected that router I mentioned above.
That is why Im thinking also about DHCP server.

Or that router had a flaky port, or wasn't configured right, since the errors went away after you disconnected that router.
