I am in a shared workspace and am trying to communicate the issues I am having with the internet performance to the workspace provider. The main issue I have other than slowness is momentary connectivity loss. For instance, when I am connected to a server via ssh every 10 seconds the connection will freeze for a second or two (it will not drop entirely). This does not happen to me anywhere else...Is there some tool I can use that could monitor the connection and shed light on this issue?

Start with good ol fashioned ping. From a windows machine, open a command prompt and run:

ping -n 100 <some external address>

Once it ends, you'll have a %loss. If you are losing more than 2-3%, I would personally complain. Also look at the average times. On a decent internet connection, you should be able to ping something like yahoo.com or google.com and get response times of 10-50ms. If you're getting response times 100+ms, then you're having pretty bad network performance.

  • Thanks for the suggestion, I had tried this already, but did again, showing no packet loss and normal response times

  • Also consider mtr which can run in a terminal window and will show you the traceroute between you and the destination along with ping / packet loss numbers for each hop.

  • An alternate one-liner for a bash shell to continually measure packet loss is while true ; do ping -c 100 <ipaddress> | grep 'packet loss' ; done, note that whether to use -n <count> or -c <count> depends on which fork of ping you are using. The default for ping is 1 second between packets.

For the ping test, i'd use PingPlotter, they have a free version that can run long term and graph your performance. However, if you want true results then i'd say run a network analyzer tool like OpsView (they also have a free version) this will give you alot more data than just ping. Sometimes ping isn't enough.
