[UBUNTU] MTU für ppp0 setzen

[mrsuicide]

Wie kann ich in Ubuntu die MTU für ppp0 ( ADSL ) setzen, ohne dass sie beim Neutstart des PCs/Shutdown des Interfaces auf 1492 zurückgestetzt wird?

Hab schon /etc/ppp/options und /etc/ppp/peers/dsl-provider probiert...

Keiner 'ne Ahnung?

Ich hab ein bischen gegoogeld und habe folgenedes gefunden:


ifconfig ppp0 mtu xxx

seemed to work. Set it to 576 or something really low when your testing
just to see :) Anyway, I'm not 100% sure this works as advertised (it
does change the MTU as reported by pppd), but it seemed to work for me.

Digging a little deeper, I found that, by default, pppoeconf sets up the
kernel-mode pppoe driver, using the roaring penguin pppd plugin. Under
this setup it seems to resist listening to any pppd specified MRU/MTU
values.

If, in /etc/ppp/peers/dsl-provider, you comment out the "plugin
rp-pppoe.os eth0" line like so:

#plugin rp-pppoe.so eth0

and uncomment

pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1412"

which should be near the top of the file, pppd uses the user-space pppoe
driver instead. And then I find that setting the MRU/MTU in is honoured,
though I don't think there is a good reason to set it to anything other
than 1412, since the pppoe driver will be clamping it to 1412 anyway.

Actually, the config is very confusing. All the documentation I found
seemed to imply that the user space deamon will be used by default,
while it is definitely not the case!


hoffe das hilft
