The second connects about 40 X-Terminals too. On all Servers is a SuSE Linux 9.0 professional installed; online updates every night. When they start up, everything is fine. After some hours when i want to do a tcpdump on one of the Interfaces i get: 'tcpdump: socket: Address family not supported by protocol' =20 ethereal doesn't find any interface. Sometimes some of the 100MBit-IFs didn't answer anymore. The only cure was to reboot. Neither rcnetwork restart nore unloading the network-module did help. This happend for a long time until there was a kernel patch from 2.4.21-215 to 2.4.21-266. Since it is installed this error doesn't appear anymore. On my home-system with a sis900 NW-IF the same happend once. But there too is kernel 2.4.21-266 now. Does someone has have made the same experience or does someone has an idea what was the reason. Thanks for any ideas in advance Greetings Hermann --0F1p//8PRICkK4MW Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQFA5X+TOtrQgwstjuoRAmUWAJ9/l6Vjs8tCHDAOR84k9njURbmKnwCgycJK xDE4TuEpV3PVOM2y2vlKLAA= =XYUq -----END PGP SIGNATURE----- --0F1p//8PRICkK4MW--
