Q:   How do I use pppd plugin pppoatm.so with multilink?

A:   There is a bug in the pppoatm plugin in pppd 2.4.4.

Attempting to use the multilink option will give the following:

pppd[3661]: Plugin pppoatm.so loaded.
pppd[3661]: PPPoATM plugin_init
pppd[3661]: PPPoATM setdevname_pppoatm - SUCCESS:0.8.35
pppd[3661]: pppd 2.4.4 started by root, uid 0
pppd[3661]: Starting negotiation on 0.8.35
pppd[3661]: Couldn't increase MTU to 1500. Using 1492
pppd[3661]: ioctl(SIOCSIFMTU): No such device
pppd[3661]: Exit.

Please recompile pppd with the patch available here.

These commands can be used to download the source, apply the patch and compile pppd:

wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz
tar -xzvf ppp-2.4.4.tar.gz
