Thanks for your ideas. Well no without any route assignment - of course I dont get anything. With the default route assignment which gets set despite the error message I can resolve hosts but cant ping anything.
I'll consider the mtu/mru settings - fact is that I prior to this didnt have set them at all and I got a warning saying they get adjusted <1500. But maybe it is as you say, that I have to adjust mtu but not mru. I have to say Im not really skilled with the internals of PPP(oE). If I do ping for now I dont get anything, no error message - maybe a timeout but I didnt wait that long. I'll also check with your ping cmd suggestions, cant check now - I'll do so in the evening. cheers Georg On Thu, 2011-07-07 at 10:05 +0000, Chris Turner wrote: > > On Thu, Jul 07, 2011 at 10:50:46AM +0200, Georg Bege wrote: > > The funny thing is, addresses do get resolved (if I dont have any > > default) I dont get anything (no dns/resolving). > > But ping doesnt get through nor any kind of connection. > > Do I have this correct: > > - without the route assignment, dns lookups are working > - with the route assignment, dns lookups are not working? > > I didn't actually see the address assignment in your ifconfig > output - was the ppp0 device output truncated or ? > > If I am correct, it sounds like perhaps some data is flowing but > not all - which could indicate an MTU mismatch > > Though I don't have direct pppoe experience on FreeBSD/DragonFly - > I did once use the OpenBSD implementation (which uses a userspace daemon > rather than the netgraph device) - > > I had some issues with the mtu matchup which caused some issues - > > My archived configuration had : > > set mtu max 1492 > # set mru max 1492 > > so you might try commenting out the mru portion? > > What does the ping of e.g. the remote gateway, show exactly? > host unreachable or something else? > > Its been a while since I debugged an MTU mismatch but iirc > if you can ping the gateway but not something else (like say your upstream > dns server ) and the routes look ok (and tcpdump is showing the packets > flowing out ) > > you can set some combination of ping -p and -D to detect the mismatch > > again, IIRC, I think e.g.: > > ping -p 1500 <routed IP? gateway IP?> > ping -p 1492 <routed IP? gateway IP?> > -> works > ping -D -p 1492 <routed IP? gateway IP?> > -> works > ping -D -p 1500 <routed IP? gateway IP?> > -> fails > > or something like this - I'd verify what I'm saying with some searching :D > > or maybe someone can chime in? > > that wouldn't explain why the config is working on one but not the other, > though I do recall that some of the default settings might be different > w/r/t freebsd, etc. in ppp from previous adventures with PPP (using GSM > devices) > > good luck! > > Cheers, > > - Chris > > > > > > !DSPAM:4e158f3a844724810620489!
