  • This will run them at the same time and timeout for each host in ten seconds. Also, mussh will append the ip addres to the beginning of the output so you know which host resonded with which time. The use of the sequence expression {1..50} is not specific to mussh. The `seq ...` works, but is less efficient.

  • clush (cluster sh) is a very powerful tool to perform this kind of tests. The [a-b] syntax is expanded by clush. You can also play with names: cn[001-010] expands to cn001, cn002, cn003 .. cn010. Note that does not expands to cn1, cn2, etc., which is very useful, cause normally servers are named cn001, cn002... cn100
