| We've been around and around with Sun on this; I have yet to talk to
| someone who struck me as halfway competent. I've been dealing with Suns
| since '82 and am no novice at this stuff, but I can't seem to convince Sun
| of that (I get bullsh*t suggestions like "are your cables making good
| contact").
but are your cables making good contact? whenever nd or nfs fails but the
network looks good to test hardware, it's because of the following:
- thin/thick net segment bad
- bad bnc, barrel, or t connector
- bad vamp connection
- bad drop cable
- bad drop cable connector/connection
- drop cable too long ("they" say 50 feet is max; i say it's 15 or 25 feet)
- giant network! (the length of every segments adds to total length)
- too many neighboring repeators (you should never have more then 2 repeators
next to each other)
in bizzare cases:
- isolan repeator power source in 220 and not 110 volts position
(repeator works but only for small packets)
(hey-- don't try this ....)
- ethernet segment ground problem ... ie: grounded to an
isolated ground ups and not mother earth.
- xcvrs set with ENCODER on ... ENCODER option should be disabled.
