Token Ring Question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi all,


I have the following configuration:

Host fw:
	192.168.4.1
	IBM TR-Adapter
	(olympic)

Host test:
	192.168.4.11
	IBM TR-Adapter
	(olympic)

The latter autodetects the Adapter, the first needs modprobe olympic and ifconfig. On both hosts, the link seems to be established on the hardwarelayer (i hear a "click" and can see the LED on the Lobe starting to light as soon as the driver is loaded. Also the two LEDs on the Adapter stop to blink at this moment).

Problem: Pinging the own address is ok, pinging the other host does NOT succeed.
root@fw # ping 192.168.4.11
root@test # ping 192.168.4.1


tcpdump shows *nothing* on fw.

tcpdump shows the following on test:
11:50:32.330239 0:20:35:84:65:14 c0:0:ff:ff:ff:ff 32:
0012 0006 060b 0000 0000 0802 0800 5a6c
1daa
11:50:32.346224 rt = c220 (2052) arp who-has 192.168.4.1 tell 192.168.4.11 hardware #6
11:50:32.346285 rt = c220 (2052) arp who-has 192.168.4.1 tell 192.168.4.11 hardware #6
11:50:32.351071 0:20:35:1:80:32 c0:0:ff:ff:ff:ff 32:
0012 0006 060b 0000 0000 0802 0020 3584
6514


Parts of the above output (11:50:32.330239 0:20:35:84:65:14 c0:0:ff:ff:ff:ff 32:0012 0006 060b 0000 0000 0802 0800 5a6c 1daa) is shown *all* the time, even without pining.

ifconfig on fw shows a IMHO working adapter:

Any ideas?!
