Hi All,
I am usuing SUSE 10.2
I have configured two gigabit ethernet cards, I have direct connection between two IBM servers(system x3650) using crossed cable, (interface eth1). However, using “scp” command to copy files between 2 machines I achieved a speed of 6-7 MByte/sec, so the same as using 100Mb Ethernet card. How can I check what is the speed at which the gigabit cards are really operating?

Output from ifconfig:

Thanks for any hints

Try the command 'ethertool eth1' ( without quotes ) to check the parameters set for eth1. If you get command not found, you may need to install ethtool first.

Hope this helps.
