hi,
I have trouble connecting a linux-box via callback to a cisco router,
using a modem (kernel 2.2.13-smp, pppd 2.3.11).
the cisco configuration should be ok, it already servers many clients.
any hint is highly appreciated!
I've set "callback <my number>" in /etc/ppp/options
and the cisco has a fixed dial-back number configured.
In the pppd-manpages I've read about an option
"+callback" without a number -
for negotiation, but it doesn't accept +callback. why?
I've attched a part of the logfile and /etc/ppp/options.
The initial connection is established properly using PAP,
after a while the callback failes ("Authentication failed")
like this:
