Re: [Linux-ATM-General] help pppoatm

[chas w. <3c...@gm...>]

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
