Systat -ifstat : some HOT network cards!



  • I thought I'd share the output of systat -ifstat on my BSD gateway. I'd better go check if the network cards have melted!

    Do we welcome our 64-bit-overflow overlords???



  • If displaying console output/code please use code or pre html tags. nbsp only works so well.



  • I tried both <pre> and [ code ], and neither had any effect in the preview. TRWTF = forum, I guess.

     

    None of the nbsp;s were my addition.

    I know. You are excused. It's not your fault.

    Let me give it a shot.

    Nah, you just plugged the network cable in the wrong way round.  Data's coming out the inputs and going into the outputs, making the calculations look negative.  But actually you're only transmitting one byte per second.  Guess there must be a lot of back-pressure when you hook 'em up the wrong way round like that.
