Some ISPs do not allow pinging because of security reasons. Check, if your ISP
allows ping. If not they probably will not allow telnet either. You should then try
to get http.
Open up lynx, type g, enter know URL. If you get a result you are connected
correctly, if not check your route with "route -n"
It should contain have at least one line looking similar to:
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 0.0.0.0 0.0.0.0 U 0
0 236 ppp0
If it does not, type:
/sbin/route add default ppp0
this command will insert the default route
You can also tell pppd to install a default route when you dial up. See "man pppd"
Hope that helps
