Hi.
I'd like some advice on how to accomplish something at the Linux command line that I have been doing at the Windows and OSX command line for years..
Okay, so sometimes it is useful in network administration to carry out a ping sweep that increases the packet size incrementally while pinging a single host. With the 'do not fragment' bit set, this can be used to quickly determine the maximum MTU between two hosts without faffing about with trial and error. Or it can be used to test a problematic connection for MTU 'black holes', whereby packets of a certain size - but not necessarily the largest - do not make it across a connection.
