Hi,
I'm running Caldera OpenLinux 2.2. I've just converted to an ISDN
telephone connection and an ISDN modem and have spent a frustratingly
large amount of time failing to solve the following problem.
I can make a PPP connection to my ISP but I can't even ping the remote
IP address he sends me, let alone go somewhere else on the Internet.
This happens both using kppp and when configuring pppd manually.
Here is a tail on /var/log/messages:
Aug 9 23:20:03 dellxps300 pppd[3413]: Serial connection established.
Aug 9 23:20:04 dellxps300 pppd[3413]: Using interface ppp0
Aug 9 23:20:04 dellxps300 pppd[3413]: Connect: ppp0 <--> /dev/ttyS0
Aug 9 23:20:05 dellxps300 pppd[3413]: Remote message:
Aug 9 23:20:05 dellxps300 pppd[3413]: local IP address 195.24.90.210
Aug 9 23:20:05 dellxps300 pppd[3413]: remote IP address 172.29.1.104
The output from route is then:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref

172.29.1.104 * 255.255.255.255 UH 0 0

0 lo
default 172.29.1.104 0.0.0.0 UG 0 0
0 ppp0
When I do 'ping 172.29.1.104' then I see the transmit and receive lights
on the modem flashing (and I see the bytes in and out ticking over if I
use 'kppp') but ping fails to get/recognize any reply.
ifconfig then shows:

RX packets:11 errors:9 dropped:0 overruns:0 frame:9
TX packets:16 errors:0 dropped:0 overruns:0 carrier:0

which seems to show that all the receive packets were in error. But what
does the 'frame:' count mean????
The problem is definitely with my Linux setup, because from Windows NT I
can connect to both my ISP's using this ISDN modem. Also, I was able to
connect to them from Linux using my old analog modem before I changed to
ISDN.
Does anyone have any idea what might be wrong here???????
Regards,
