Hello,

Does anyone know if there is a program like Winsock Packet Editor for linux?
I'd like to be able to alter the content of a packet as it is being sent or
received.

Thanks

Thanks for the suggestion. I could only find information about altering the
routing information. I'd like to alter the data in the packet. Have I
overlooked something?

You can use iptables(8) to direct a packet to a queue for userspace
processing /before/ it is passed along to the sockets layer. Thus, you can
intercept and alter packets before they are put on the wire or passed to an
application.
