First you should update this system to 6.3 release. Also you should post how your interfaces are configured, you can copy and paste the output from: ifconfig -a You also need to better explain the topology of your network. For instance are all 13 systems on the same subnet? or are you running multiple subnets with a switched backbone? How many switches are you using? Are you checking the throughput across a LAN segment or across multiple subnet segments? -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
