While downloading [anything], you do ping in terminal, to facilitate data x-fer. Like grease in the machine, singing for someone who stutters, mechanical snake in the plumbing, etc.
No response tho', from the ISO d/l site???

Where's the server? No response to ping call? How many layers in the onion router? 
There is no need to be root or for that matter to have 'SU' powers to use ping.

It could be that the server drops all ping requests, meaning you would see nothing when trying to ping. Pinging a server while doing a data transfer should not make it work any better or faster. If it does there are other issues going on.
