You should look at "netstat -i" and check for packet errors, perhaps, as well as double-checking cabling and duplex and so forth. This makes a nice network test: ping -i 0.001 -s 1450 -c 100 host.example.com If you adjust "sysctl net.inet.icmp.icmplim" upwards, you can change the count to send as much data as you want. Using a big size is assymmetric and involves much more data sent from the machine running the commmand than is received, using the default side sends roughly equal amounts of data. -- -Chuck
