Restricted ssh login shell for mercurial
hg-ssh can be used as a restricted shell where access to Mercurial repositories is given over ssh(1). It should be specified, together with the paths to the repositories the user should be given access to, as a command option in an authorized_keys(5) file.
An example authorized_keys line using hg-ssh:
command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-rsa AA...==
The user with the specified key would then be permitted to push and pull to the repositories using the URLs:
ssh://example.com/path/to/repo1 ssh://example.com//path/to/repo2 ssh://example.com/~/repo3 ssh://example.com/~user/repo4
sshd(8), ssh(1), hg(1).
