Aha... when ping sends out a ping request in -f mode it prints a ., when
it gets the ping response it backspaces it. Therefore a happy network
shows a single flickering dot. So you learned that either that server
is unable to keep up with network traffic or you have some other problem
causing packet loss between the two boxes.
Examine the cable, switches and hubs, and also if possible the
negotiated mode at the Ethernet PHY, using, eg
mii-tool eth0
