Bastion

SSH bastion that features transparent connection and session recording.

This project is inspired by https://github.com/moul/sshportal. I wrote this implementation to work around the fact that I couldn't get the go ssh lib to work properly with non interactive sessions, the bug has been open for a long time and I tend to belive it cannot be fixed (https://github.com/moul/sshportal/issues/55). This one does work properly with non interactive sessions, which allows transparent ansible usage through the bastion.

Dependencies

This project has only one hard dependency :

  • the libssh from https://www.libssh.org/. You should be able to use your distro's packages if they are recent enough.

The following are optional dependencies :

  • the libtty from https://github.com/kilobyte/termrec which allows session recording.
  • compression libraries like libbz2, liblzma, libz allows to compress on the fly session records.
  • libmysql for now because it hosts the runtime config

Manual Installation

This project is built using cmake :

mkdir build
cd build
cmake ..
