Something like "tcpdump -s 9000 > -w dump.out"... but I have two different tasty cases of data corruption using NFS over UDP traced for you which I'll send you in private. The first one corrupts init so that it segfaults, the second one probably crashes the rc starter to that I'm left with an unusable getty login on console. I'll try to get the TCP problems traced as well but right now I don't have the time to wait.... --=20 Servus, Daniel --=-UZhwYHiPEInvEd3gq1qQ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iQEVAwUAQIE76jBkNMiD99JrAQJpCggAn8KafG6gptPVjwl88v3gFzbk69m+wrd/ k5MObKzX1195CU9K18OeLpe+Jrwh5qH6UNPJz6cViM88BzvPvJlYtXz5EjVgQzaT ZRYWpoYbcXkhyhE0tsNZKcednxH1KmlBR5t/L3bqMaMsnknq2rY+2bdxDZ1BbaK5 eqjWdr+I8OODzLgxS2kexlsRTbYlFfw1eQ4O5Hu+T1LlXxkLHMQS4Bc2OUxwaagN f8uXnlcrYVuny9zTX17BJuwxMl6SpvB5RlrWkxXDhPp/R5NKVwpEYXL6u5xZYWWD 5rpWJOmJ6RXTWMcE0FTb73FJgwnvEdpwRWVSK0bOo1m6lcDAODSaeQ== =XePI -----END PGP SIGNATURE----- --=-UZhwYHiPEInvEd3gq1qQ-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
