Re: Network problems
:Hi,
:
:this started with an upgrade about 1-2 weeks ago (well, it started with
:*something* that happened 1-2 weeks ago). Network (packet forwarding?)
:stalled every 6-12 hours. Today I did another upgrade (no configuration
:changes) and now it happens every 30-90 minutes.
:
:This box is my router connected to the net by an rl interface (via
:pppoe) and connected to the internal network by an sis.
:
:When it hangs I can do:
:
:# [kill ppp]
:# ifconfig tun0 down
:# ifconfig tun0 up
:# [start ppp]
:
:Then I get a:
:
:Working in ddial mode
:Error: bundle_Create: ioctl(TUNSIFMODE): Device busy
:Using interface: tun0
:
:After which everything works normal again. If I leave out the down/up of
:tun0 I won't get an error from ppp but it will use tun1 instead which
:doesn't work.
:
:I could provide tcpdump output for both interfaces if there's interest.
:
:Sascha
This seems eerily familiar. I seem to remember we had a similar
problem with the tun interface a while ago.
Try to narrow down the date at which it stopped working by downloading
snapshot kernels (assuming you don't have to load any modules to test
the issue).
