Re: Loosing Ethernet Connectivity

Hey,

sure, i can do a script which does the up-down when it cant ping the router or something, but to be honest i think that is not a production solution. cheap nic..maybe, some of the nics in question where onboard ones, which are not the best ones out there, but others, such as the 3COM 3c90b5 Fast Etherlink XL PCI, is that also a shitty one? I also have a tried a simple D-LINK and a Realtek one. It seems that under a certain condition FreeBSD just shuts down its Networking, and if thats true i wonder if that can be done remotely, that would not be cool.

Perhaps, however, just doing a cron job every day to do the ifconfig
down/up would be a simple work-around.

Hello all,

every once in a while i have a machine (6.1) that out of the blue,
sometimes after days, some after 6 months, looses Ethernet
Connectivity. My Machines just run some Service, and have no
Keyboard / Mouse or Monitor. When the Machine goes down, eg, i am
unable to ping it from another Machine on the Network, even
restarting the machine using "reboot" will not fix the Problem. The
only way to fix it is to login as root, and issue a "ifconfig vr0
down && ifconfig vr0 up". Then a dmesg Message appears : "vr0: Using
force reset command.", and after that i can successfully ping the
machine again. I have had this Problem on different machines with
different Network Cards, on different Ethernet Cables, and with
FreeBSD Versions 5.5 until 6.1.

Can anyone please help me to understand and possibly even fix this
Problem?

Thanks a lot,
David
