Does anyone know a way I can test a Linux servers connection speed from ssh? I could use wget but I can't find a file that can be downloaded fast enough. I'm trying to verify that the server can do a gigabit per second.


You might want to try using iperf for bandwidth measurements


You could use something like the aria2c downloader. It's like wget, but it supports more methods of downloading, including splitting a file up and downloading bits of it from multiple sources. So, you could find a bunch of mirrors for some popular linux distro and have aria2 download from a bunch of them all at once. If you aren't maxing the line, just try adding more mirrors. Crude, but if you can't find a better method it might come in useful.


This will create 1Gigabit file named out.bin. Change the bs parameter value for a greater file.

dd if=/dev/zero of=out.bin bs=1000000000 count=1
