Pdump

If you're looking for a network packet sniffer, the Pdump project (Packet dump) may be what you need. Installation is straightforward, with the package's source code easily configured for your system by running `./configure` in the source code directory. If you're using `csh` on an old version of System V, you'll need to type `sh ./configure` instead to prevent `csh` from trying to execute `configure` itself.

While running `configure`, you'll see messages telling you which features are being checked for. Once configuration is complete, the next step is to compile the package with `make`. If you want to run any self-tests that come with the package, type `make check` first. Finally, to install the programs, along with any data files and documentation, type `make install`.

You can remove the program binaries and object files from the source code directory with `make clean`. To also remove the files that `configure` created, type `make distclean`. If you're a developer working on the package, there's a `make maintainer-clean` target, but it's not necessary for regular users. Just be aware that if you do use it, you may need to get other programs to regenerate some of the files that came with the distribution.
