- The API that is sufficient for building of standalone SSH clients and servers, or for embedding client/server functionality in your lispy Scheme applications.
- Several authentication methods are supported, including password authentication, public key and SSH agent authentication methods.
- Key management procedures: you can make key pairs, read keys from files, get key hashes, get public keys from private keys etc. DSS, RSA, RSA1 and ECDSA (by means of OpenSSL) are supported.
- Port forwarding procedures and high-level API for creating of SSH tunnels.
- Distributed forms (
distribute, …) that allow to spread the evaluation of Scheme code between remote hosts. Or you can just connect to a remote REPL from Scheme using
with-sshprocedure and evaluate some expressions. No special server needed on the remote side, just an SSH daemon and GNU Guile installed!
- SFTP client API allows you to read and write remote files over the SSH protocol right from the Scheme code.
- Remote popen API that allows you to make either input, output or bidirectional pipes to remote processes.
- Detailed documentation in Texinfo format with examples included, even more

The library can be installed by the following means:
- Using GNU Guix: https://www.gnu.org/software/guix/
- Using Arch GNU/Linux AUR package: https://aur.archlinux.org/packages/guile-ssh/
- Using Parabola GNU/Linux package: https://www.parabola.nu/packages/?q=guile-ssh
- Manually. If you’re considering manual installation, see the notes below.
Thanks for all the people who helped with packaging of Guile-SSH!
Also there is a Docker image based on Debian GNU/Linux that contains the latest version of GNU Guile and Guile-SSH installed – give it a try!
For a basic explanation of the installation of the package, see the INSTALL file.
Please note that you will need Automake 1.12 or later to run
make check (but the library itself can be built with
older Automake version such as 1.11).
important You probably want to call configure with the
--with-guilesitedir option so that this package is installed in
Guile’s default path. But, if you don’t know where your Guile site
directory is, run
configure without the option, and it will give you

examples – you can open it by typing
info guile-ssh in the shell, or using
C-h i m guile-ssh RET combo in Emacs. Also take a look on examples in the
