pppd AuthAck problem

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

hi,

i am trying to set up a ppp-server with debian linux 2.1 and an=20
elsa microlink isdn/tl v34 external modem.

mgetty picks the call and starts pppd. pppd handles userauthentication=20=

successfully but then needs a lot of time to send back the =20
=84PAP AuthAck id=3D0x1=93.

in that time windows95 clients hang up, so that pppd gets an =84write:=20=

warning: Input/output error(5)=93 while sending the auth-ack.

what is wrong? can anybody help me?

thank you, benedikt.
