I don't happen to have any atm hardware right now, but using adummy,
I get pretty far:
# modprobe adummy
# /sbin/pppd plugin pppoatm.so 8.32 nodetach debug
Plugin pppoatm.so loaded.
PPPoATM plugin_init
PPPoATM setdevname_pppoatm - SUCCESS:8.32
using channel 3
Using interface ppp0
Connect: ppp0 <--> 8.32
sent [LCP ConfReq id=0x1 <magic 0xdae9c590>]
sent [LCP ConfReq id=0x1 <magic 0xdae9c590>]
sent [LCP ConfReq id=0x1 <magic 0xdae9c590>]
If you leave that running and poke around in /proc/net/atm, you
should see outgoing traffic:
% cat /proc/net/atm/devices
Itf Type ESI/"MAC"addr AAL(TX,err,RX,err,drop) [refcnt] 0 adummy
000000000000 0 ( 0 0 0 0 0 ) 5 ( 42 0 0 0 0 ) [2]
[forgive me if my mailer wraps this wrong]
Make sure the pppoatm module gets loaded into the kernel using
lsmod
lsmod | fgrep pppoatm
You need both a userspace module for pppd and a kernel module pppoatm.ko
