So I tried the ff:

glenn at puck:glenn/$ sudo route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
localnet        *               255.255.192.0   U     0      0        0 eth0
default         138.67.1.1      0.0.0.0         UG    1      0        0 eth0
default         138.67.1.1      0.0.0.0         UG    1      0        0 eth0

Before that was finished, I think, in another terminal I ran

glenn at puck:glenn/$glenn at puck:glenn/$ sudo wvdial &

and /var/log/messages said

Dec  6 06:59:57 puck pppd[790]: pppd 2.3.11 started by root, uid 0

Dec  6 06:59:58 puck pppd[790]: remote IP address 138.67.1.16

At this point I could ping 138.67.57.35 but nothing else I tried.  I
ran "route" again:

glenn at puck:glenn/$ sudo route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
138.67.1.16     *               255.255.255.255 UH    0      0        0 ppp0
localnet        *               255.255.192.0   U     0      0        0 eth0
default         138.67.1.1      0.0.0.0         UG    1      0        0 eth0
glenn at puck:glenn/$

and /var/log/messages said

Dec  6 07:03:09 puck kernel: eth0: flipped to 10base2
Dec  6 07:03:10 puck kernel: eth0: coax cable problem

As always, any help appreciated.  I didn't have time to try the /cdrom
suggestion; I'll try tonight.  I haven't changed any /cdrom link or
fstab so it seems strange to me that installing a new kernel image
would make it stop working.  Perhaps by tonight I'll be able to
connect via Linux and report success!

Thanks,
