all right, that's the whole story:
I start from

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
127.0.0.0       0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         127.0.0.1       0.0.0.0         UG    0      0        0 lo

then I bring down eth0 by doing "ifconfig eth0 down"
and that's what I get with route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

then I dial out, using wvdial and when pppd connection comes up I get:
--> Carrier detected.  Waiting for prompt.
--> Don't know what to do!  Starting pppd and hoping for the best.

--> primary   DNS address 194.185.97.134
--> secondary DNS address 194.185.97.134

and the route table is

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.100.101 0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
0.0.0.0         127.0.0.1       0.0.0.0         UG    0      0        0 lo

I can't ping anybody but myself and the gateway.
The I add the default gateway by hand and get

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.100.101 0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
0.0.0.0         192.168.100.101 0.0.0.0         UG    0      0        0 ppp0
0.0.0.0         127.0.0.1       0.0.0.0         UG    0      0        0 lo

now I'm up and running, like now.
In fact, it might be useful to say, that I think I started getting these
sort of problems after I installed and configured netenv, which I did
because I move around in different network situations. This particular
problem is now on my gprs connection, but I have it also on a normal ppp
session with a normal isp through thelephone (I think). I don't know if
there maybe any problem with netenv.
When I'm not in the office, or in any network environment, I usually run
netenv in such a way that my /etc/network/interfaces is just

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

so I configure pretty nothing but myself, I think, so I shouldn't have any
default gateway conflicting with the new one anyway, and my route table
says so. Anyway, that's the whole story....puzzleing?

Hmmm...that I don't know how to do....I bring pppd up with wvdial, and my
/etc/ppp/peers/wvdial file is just

noauth
name wvdial
usepeerdns
defaultroute

I added the defaultroute by hand, but I don't know if that's any
use....I'm really not a ppp expert and every time I try to bring up pppd
with pon or with pppd call ... I seem to get nothing. That's why I like
wvdial....bad?

If anybody has any idea....
thanks a lot
