What tools should every sysadmin use that no one’s heard of? [closed]

iPerf

Iperf helps you run tests that measure maximum TCP and UDP bandwidth performance. It allows the tuning of various parameters and UDP characteristics reporting bandwidth, delay jitter, datagram loss: http://openmaniak.com/iperf.php


,And

MTR

MTR (My Trace Route) is also a pretty good tool. It combines the functionality of the ‘traceroute’ and ‘ping’ programs in a single network diagnostic tool. Like traceroute except it gives more network quality and network diagnostic info. Leave running to get real time stats. Reports best and worst round trip times in milliseconds… It shows latency, jitter (average/best/worst): http://www.bitwizard.nl/mtr/

use:

mtr server.domain.com (or IP)

  • Add more fields with “O”, type “LDRS NBAW V JMXI” and hit ENTER
  • Type “n” to toggle DNS Off/On
