Best way to check for a duplex mismatch, IMO, on UNIX/Linux (similar command and similar output on most *nix): $ netstat -ian (or equivalent) Name Mtu Net/Dest Address Ipkts Ierrs Opkts Oerrs Collis Queue lo0 8232 127.0.0.0 127.0.0.1 37305 0 37305 0 0 0 bge0 1500 130.219.34.0 130.219.34.167 543932 0 212934 0 0 0 ...if I had a problem here, I would very likely see a nonzero number of Ierrs or Oerrs, and possibly also Collis (when I should never see collisions on a switched network, really, with very few exceptions). I've had problems like this also due to below-spec cabling, but most frequently it's duplex. - -- ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - Systems Programmer III |$&| |__| | | |__/ | \| _| |[EMAIL PROTECTED] - 973/972.0922 (2-0922) \__/ Univ. of Med. and Dent.|IST/AST - NJMS Medical Science Bldg - C630 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFyQeZmb+gadEcsb4RAl/dAJkB71+7OMFWHam3fBPpUPSh7SpViwCaAwsz +URyRq5qucK65XyEac4ZNEM= =FFE9 -----END PGP SIGNATURE----- ------------------------------------------------------------------------- Using Tomcat but need to do more?
