This commit implements the ssh exec channel request. It also handles some shortcommings on the interactive channel like exit and concurrent session establishments. Pipes into the channel do not work yet. E.g.: echo foobar | ssh noux@localhost -p 5555 "cat > /rw/test.txt" The issue described with FIXME in Ssh::Server::incoming_connection() could not be reproduced and might have been fixed with the improved file descriptor handling. Fixes #3401
