mgetty multilink ppp problem

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Hi,

I'm having a problem with mgetty (1.1.21) and a multilink ppp device
(external ISDN
TA).  Any help with the following would be greatly appreciated.

I'm using mgetty to facilitate dial-in services on a machine running linux
kernel version
2.2.13.  When I set up the ISDN 'modem' to receive calls, and to NOT use
multilink
ppp, everything works great and I get this in my logfile:

However, when I set my ISDN TA to use multilink PPP as its protocol, things
do not
go as smoothly.  The device answers, but then mgetty just hangs (/AutoPPP/
is never
found during getlogname) until the connection resets.  Here's what it looks
like in the logs:

Again, thank you in advance for your help sorting this out.  Newsgroup
followups
or email to mtayor@cl-sys.com are fine.  I check both.
