How do you check link speed ?

I'm copying files from one Solaris box to another, how do I check the throughput I'm getting ?

I've used ndd to confirm both are set to 100 full, but how do I check the actual throughput ?

You will probably need to download a separate program. There is a program called nttcp, which will open up a connection between two machines and tell you the throughput.

Actually I think it's called NPtcp.

You can also try the spray utility.

It is called nttcp and was compiled for Solaris, it is originally for SGI systems I believe.

Okay, apologies; there is another utility called NPtcp which does a similar job and is excellent for benchmarking network throughput.

It probably is the same program anyway, LOL.

Try iftop. It will tell you the throughput and is available on
