Well, I know its possible, using external libraries and modules such as scapy. But how about without external modules? Without running the script as root? No external dependencies?
I’ve been doing a lot of googling, but haven’t found much help. I’d like to be able to create my own packets, but without running as root, or installing extra dependencies.
Any suggestions?
Many operating systems (Linux) do not allow raw sockets unless your effective user ID is 0 (aka root). This isn’t a library issue. Some operating systems (non-server Windows post Windows XP SP2) do not allow crafting raw sockets period.
You can read more about raw sockets by man 7 raw on your system. Note that the socket options can all be passed using the Python socket module.
