The ATM utility commands don't know about the NICStar type... > the attached please find my atmdump and message files that you need.thank > you! The /var/log/messages file seems wrong and/or incomplete. The atmdump trace shows activity from about 16:40 through 17:00. The message file starts with a reboot at 17:09 but ends with the "badpdu" messages from 17:00. I'm guessing that the reboot messages are from a reboot AFTER the tests you ran. I need to see the /var/log/messages file from the period when you actually ran the tests above. In particular, you should see a line like the following: uni: set address 0x47....... on interface idt0 in this area of the messages file when you issue the 'atm set prefix' command. > Dec 22 17:00:00 mars /kernel: sscop badpdu received: vcc=(0,5) > Dec 22 17:00:00 mars /kernel: : bfr=0xf56cb380 data=0xf5556710 len=48: The badpdu errors indicate that the driver is delivering the SSCOP PDUs with an incorrect length. It appears that the length includes the entire AAL5 length (48), not the SSCOP PDU length (8 for these PDUs) - SSCOP is rejecting these during its PDU validation process. The missing messages may help with this, plus maybe Mark can comment on this. -- Mike Spengler Network Computing Services, Inc. Email: mks@networkcs.com 1200 Washington Ave. So.
