Network traffic

Unread postby JacquesT » Tue Apr 17, 2018 11:54 am

Could anybody advise how to check for transfer speed (bits or bytes) via ethernet port? I'm busying transferring stuff from my debian NFS server and it's taking for ever, even for a measly 600mb.

Could be either command via debian / irix. Thanks.

I like to use gkrellm on linux if I have ssh access and X on the client.

Gives all the usual telemetry suspects like cpu, mem, swap, load, disk + network. Gives friendly human values like K etc.

Otherwise under linux you could use any of these (bmon is nice):

If you only have tcpdump,

substitute the correct interface

Code: Select all

# tcpdump -i en0 -nn -tt  | perl -ne '($ts) = (/^([\d\.]+)/); ($l) = (/length (\d+)/); $int+=$l ; if ($ts-$p >= 1 || eof) { printf("%02d:%02d:%02d %10.2f Mbytes/s %s\n", (localtime($p))[2,1,0], $int/1024/1024, "." x ($int/1024/1024)); $p=$ts; $int=0;}'

14:41:45       3.98 Mbytes/s ...
14:41:46       2.03 Mbytes/s ..
14:41:47       3.76 Mbytes/s ...

umm, nettop is a text console"top"-like program for network activity
I am tattooed in reverse, cause if you break rules you don't know where it leads.
