Re: Make nping output more like Unix ping?

["Luis MartinGarcia." <luis.mgarc () gmail com>]

Hi, Jacek.

Sorry for the late reply. I do understand your need to quickly see the
RTT but unfortunately nping does not offer that possibility yet. Of
course it offers RTT statistics at the end but at this moment there is
no way to see RTTs displayed in the RECV packet output line.

I'll make a note about your request and add it to the to-do list.

Best regards,

Luis MartinGarcia.
