calling functions at the same time

[asdf sdf]

sigh. i just read what you want to do.

my answer was so cool too.

you are doing network diagnostics. it is unlikely that a non-network guy 
(you) can cobble together a few lines of script and develop much in the 
way of detailed diagnostics.

much better to find someone who already knows networking and use the 
great many highly sophisticated tools that are already available (and free).

good luck
