How do I troubleshoot an internal interface
I'm new to BSD. I have an OpenBSD box acting as a firewall and dhcp server connected to a Linksys N-wireless router configured as an access point/switch.
About once a day the internal interface (nfe0) will seem to drop and my internet will go down. I cannot ping the firewall but from the OpenBSD machine I can ping the router and broadcast. The strange thing is, the latency is +5000ms. If I perform a "ifconfig nfe0 down & ifconfig nfe0 up" the connection will restore itself and all is fine. I checked everything in /var/log/ but could not find anything timestamp'd near when the problem occurred. I've tried disabling pf and the problem persists. I'm thinking that I have a bad cable or port that is causing the connection to drop to 10/half but I don't know how to check that, or if that would even cause high latency! So my real question is, how can I effectively troubleshoot my internal interface? Thanks, Nathan |

I just got back from work and my internal network has been down and a ping of my router reports "Host is down" instead of the +5000ms response. I did an ifconfig -A and my nfe0 (internal interface) reports 100/Full duplex.
/var/log/messages Code:
Aug 30 18:45:35 triforce dhclient[12186]: routehandler: interface down Code:
# dmesg | grep nfe0 nfe0 at pci0 dev 7 function 0 "NVIDIA MCP61 LAN" rev 0xa2: apic 2 int 10 (irq 10), address 00:1e:90:3e:ad:95 rlphy0 at nfe0 phy 1: RTL8201L 10/100 PHY, rev. 1 nfe0 at pci0 dev 7 function 0 "NVIDIA MCP61 LAN" rev 0xa2: apic 2 int 10 (irq 10), address 00:1e:90:3e:ad:95 rlphy0 at nfe0 phy 1: RTL8201L 10/100 PHY, rev. 1 |

The problem you're experiencing tends to show up from time to time with certain drivers and/or buggy chipset revisions, the exact cause of your problem is unknown and there is very little we can do to help you here.
It might be a good idea to install another card and see if that helps, alternatively, try replacing the cable. You should send a bug report, right now, the gnats system is down, so try sending an email to bugs@ or contact the authors mentioned in the man page. |

Thanks man! I'll look for a new/better card and see about submitting a bug report! |
