You can easily test out Linux/UNIX network Load using standard dd and scp commands.
=> Use dd to create a large file.
=> Use scp to copy file from one system to another system. scp copies files between hosts on a network. It uses ssh for data transfer, and uses the same authentication and provides the same security as ssh. Make sure both local and remote system owned by you i.e. co-operation from another host on the network is required for test network load.
Step # 1: Create a large file
Use dd command as follows to create a large file (e.g. 1024M x 2count = 2GB):
$ dd if=/dev/zero of=/tmp/big.file bs=1024M count=50
Step # 2: Use scp to transfer file
Now copy a file to remote host using scp:
$ scp /tmp/big.file email@example.com:/tmp
Any error or crash indicates problem with system load testing.
Please note that if the server has two+ network cards, make sure that the test is run and uses each of the network cards. Disable NIC using ifconfig command or alter routing using route command for testing purpose.Share this on:
