Hi from what i can tell is the overun is because you have had a buffer overrun on the network card eg more data has been sent to the card from another computer than the computer can process. except you should not get 1 on the TX stats. these are more common on a 486sx33 or so :) eth0 Link encap:Ethernet HWaddr 00:A0:24:83:2E:15 inet addr:192.168.1.6 Bcast:255.255.255.0 Mask:255.255.255.0 inet6 addr: fe80::2a0:24ff:fe83:2e15/10 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:838304 errors:219 dropped:0 overruns:227 frame:219 TX packets:758826 errors:0 dropped:0 overruns:0 carrier:4 collisions:1443 txqueuelen:100 RX bytes:224044357 (213.6 Mb) TX bytes:124675867 (118.9 Mb) Interrupt:5 Base address:0x220 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:145682 errors:0 dropped:0 overruns:0 frame:0 TX packets:145682 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:11293779 (10.7 Mb) TX bytes:11293779 (10.7 Mb) ----- Original Message ----- From: "Casey Carter" <Casey@Carter.net> To: <linux-net@vger.kernel.org> Sent: Friday, December 07, 2001 7:45 PM Subject: Re: How do I find the cause of these errors? > That's one of the cool things about us Linux geeks.
