libssh

The SSH library

This project is for programmers needing a working SSH implementation by the mean of a library. The complete control of the client is made by the programmer. With libssh, you can remotely execute programs, transfer files, use a secure and transparent tunnel for your remote programs. With its Secure FTP implementation, you can play with remote files easily, without third-party programs others than libcrypto (from openssl), libgcrypt or mbedTLS.

git-into-gsoc org "libssh" --shortlist
git-into-gsoc repos "libssh"
git-into-gsoc issues --org "libssh"

or ask your assistant:
"Which libssh repositories merge
newcomers' pull requests, and which beginner
issues are still free?"

Those commands read live data: which repositories merge outside pull requests, and which beginner issues nobody has claimed. Install in two minutes.
