Ed and Jim,
Thanks for the comprehensive replies.
My private network is a home office network with a linux box and two win98
boxes for the kids. I want the link brought up whenever the kids or I need
to access the internet (e.g., www, ftp, irc, AIM, icq). There will be no
restrictions on that.
As Ed is doing, I'd like to configure the link so that it does NOT come up
for named or netbios packets or any other kind of routing packet. Once the
link is up, I don't mind if my internal DNS server (not running yet) gets
configured with packet traffic. I also would not mind doing time
synchronization once the link is established for regular internet access.
Would it make sense, then, to go with diald and forgo pppd's more limited
control? Also, I'd appreciate a copy of Ed's diald configuration script
since I think it matches what I am going to try to do.
Thanx!
...Jake
