[CLUE-Tech] L2TP for dial-up?

[Robert Woods]

L2TP Stands for Layer Two Tunneling Protocol.
Look in /etc/services.

Your connection to the modem is serial hence the connection through the 
modem is considered a serial connection.

Look in file /etc/sysconfig/network-scripts/ifcfg-ppp0 (RedHat 9)

This file defines the conversation between your computer and the ISP. I 
suspect you will find something in this file that looks like "expect PPP".

Sorry I have not used PPP for a while and I can not be more specific.

Seems to suggest you might also need to look in: 
/etc/sysconfig/network-scripts/chat-ppp0

look at L2TP.


<http://www.l2tpd.org/>This site suggests you might need additional 
software to work with the protocol.

Good luck. Looks like it might be quite involved. :-(
