Re: resetting /proc/net/dev && ifconfig shows lots of dropped and errors

This is a great question that I came across recently and didn't have an answer for. How do you clear ifconfig and netstat counters under GNU/Linux?

I remember Solaris having a netstat flag that will clear some counters, but I don't know of anything for Linux.

It's very valuable to be able to clear your counters while troubleshooting a problem. However, I can also see this being a problem since many tools might depend upon those counters not being reset.

...short of rebooting is there a way to reset /proc/net/dev ?

Do the errors and drops seem high?

dropped/recieved is .3%
errors/transmitted is 84%  !??!!

We haven't noticed any application errors on this machine (dedicated to mailman)

"carrier" means what?

Snooty pointers to the fine manual would be A-OK as well.
