Since 2 weeks i had to call my ISP like 6 or 7 times to get my DSL link fixed. As i use my gentoo box at home via VPN for all kinds of Webdav, email etc. solutions i was looking for a backup to get INTO that router once the connection fails due the DSL being broken again.
Time to bring my old AVM ISDN card into the game again. I wanted a solution that allows me to DIAL IN to my router via my PowerBook via mobile, getting a proper IP connection to it, mainly for SSH to fix the DSL or whenever necessary to SURF over this connection.
After a lot of searching (this topic seems to be outdated with all this DSL, UMTS around) i finally came up with this configuration:
/etc/ppp/peers/dialin
nodefaultroute
10.50.50.1:
ms-dns 192.168.100.1
noipx
proxyarp
sync
plugin capiplugin.so
msn 123456 #change to local msn
protocol hdlc
cli 123456 #change to dialing number
login
mp
nodefaultroute
unit 5
auth +pap
The authentication uses /etc/ppp/pap-secrets and expects something like this:
#username localhostname password ip_for_dialing_host
dude router blub 10.50.50.2
/etc/inittab
#in order to have the card LISTENING all the time.
p0:23:respawn:/usr/sbin/pppd call dialin
