quick question

[noleks at lsil.com (Nick Oleksinski)]

Has anyone ever seen a situation where outgoing pings from a machine are
slow on a LAN but ping reflections (ie another machine on the LAN
pinging the Linux box) are very fast?  I'm getting this on a Linux box
using a 3Com 3C905C-TX ethernet card and kernel 2.4.1.  The times look
something like this:

FROM ANOTHER MACHINE TO THE PC (wmpc75):
noleks tcsh[2]$ ping -s wmpc75
