I'm just trying to get a simple desktop dialup setup working. I haven't set up any LAN. I'd like to be able to use ppp-on/off as a regular user, but for now I just want to get it working for root. I'm running a stock Slack 9.1 install with bare.i.
I've run netconfig and told it I just want to setup a loopback connection (for "modem or no net").
I've run pppsetup and given it the usual input.
I can run ppp-on as root and get my external modem to dialup and connect. /var/log/messages tells me:
-- got it
Serial connection established.
Using interface ppp0
Connect: ppp0 <--> /dev/modem
Once connected, If I try to ping the one dns IP in my /etc/resolv.conf, I get:
connect: Network is unreachable
If I try to ping something else
Trying to traceroute the IP of my DNS listed in /etc/resolv.conf
traceroute: findsaddr: Can't find interface
Running 'ifconfig -a' lists eth0, lo, and ppp0. In the ppp0 section, there's no "inet" or "UP" lines present like there are when I haven't run ppp-on.
