I'm trying to get callback over ISDN to work.
/etc/start_if.tun0 contains:
ppp -auto tue-isdn
/etc/ppp/ppp.conf contains:
default:
set log Phase Chat Connect Carrier LCP IPCP CCP tun
set server 3000 ""
set device /dev/modem
set speed 115200
set redial random 0
tue-isdn:
set phone NUMBER
accept chap
accept pap
set authname jbackus
set authkey mypass
set timeout 0
set redial 1 1
set log Phase Chat Connect Carrier LCP IPCP CCP tun
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATZE0Q0 OK-ATZE0Q0-OK \\dATDI\\T TIMEOUT 40 CONNECT"
set login "TIMEOUT 60 \"\" !/usr/local/sbin/isdn-auth CONNECT"
set ifaddr 10.10.10.10/0 10.10.11.11/0 255.255.255.0
add 0 0 10.10.11.11
tue-isdn-auth:
accept chap
accept pap
set server 3001 ""
set authname Cjbackus
set authkey mypass
set timeout 0
set log Phase Chat Connect Carrier LCP IPCP CCP tun
ppp.log excerpt of the ``ppp -direct tue-isdn-auth'' session:
Apr 27 01:13:04 jos ppp[376]: tun1: Phase: Listening at port 3001.

/usr/local/sbin/isdn-auth contains:
#!/bin/sh
/usr/sbin/ppp -direct tue-isdn-auth
exit 0
This script authenticates me to the terminal server, so it will know who to
call back.
Now the problem:
When ppp is run at bootup, everything works.
But when I kill ppp and restart it with ``sh /etc/start_if.tun0'', I get the
above select()-related error. But when I run ``ppp tue-isdn' and give the dial
command, everything works again!
Hence the question:
Why does -auto only work at bootup?
Thanks,
