Scapy: a powerful interactive packet manipulation program

Can scapy or any other util modify packets on the fly?

I've always wanted an "nsed" -- to mimic the "ngrep" idea. A quick and dirty way to, for example, modify HTTP headers on the fly.

I can't say I have tried, perhaps I will later, but how about netcat piped to sed? Also, check out burpsuite for most of that functionality.. just not cli based.

it can, yet, headers such as checksums will have to be handled as well.
