Folks,
can anyone explain in simple terms what "tcpattemptfails" ( netstat -s )
means and what perhaps would cause this to increment around 10-15 units per
30 seconds ?
We have a situation where we moved servers into a new firewall complex and
suprise suprise, it is terribly slow and users have been complaining. ive
been running netstat, ping -s etc..and have the following results.
qcmw002z# ping -s au1240s
