ограниченная оболочка входа для доступа по SSH только Git (Restricted login shell for Git-only SSH access)
Имя (Name)
git-shell - Restricted login shell for Git-only SSH access
Синопсис (Synopsis)
chsh -s $(command -v git-shell) <user>
git clone <user>@localhost:/path/to/repo.git
ssh <user>@localhost
Описание (Description)
This is a login shell for SSH accounts to provide restricted Git
access. It permits execution only of server-side Git commands
implementing the pull/push functionality, plus custom commands
present in a subdirectory named git-shell-commands
in the user's
home directory.
Команды (Commands)
git shell accepts the following commands after the -c
option:
git receive-pack <argument>, git upload-pack <argument>, git
upload-archive <argument>
Call the corresponding server-side command to support the
client's git push, git fetch, or git archive --remote
request.
cvs server
Imitate a CVS server. See git-cvsserver(1).
If a ~/git-shell-commands
directory is present, git shell will
also handle other, custom commands by running
"git-shell-commands/<command> <arguments>
" from the user's home
directory.
INTERACTIVE USE
By default, the commands above can be executed only with the -c
option; the shell is not interactive.
If a ~/git-shell-commands
directory is present, git shell can
also be run interactively (with no arguments). If a help
command
is present in the git-shell-commands
directory, it is run to
provide the user with an overview of allowed actions. Then a
"git> " prompt is presented at which one can enter any of the
commands from the git-shell-commands
directory, or exit
to close
the connection.
Generally this mode is used as an administrative interface to
allow users to list repositories they have access to, create,
delete, or rename repositories, or change repository descriptions
and permissions.
If a no-interactive-login
command exists, then it is run and the
interactive shell is aborted.
Примеры (Examples)
To disable interactive logins, displaying a greeting instead:
$ chsh -s /usr/bin/git-shell
$ mkdir $HOME/git-shell-commands
$ cat >$HOME/git-shell-commands/no-interactive-login <<\EOF
#!/bin/sh
printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
printf '%s\n' "provide interactive shell access."
exit 128
EOF
$ chmod +x $HOME/git-shell-commands/no-interactive-login
To enable git-cvsserver access (which should generally have the
no-interactive-login
example above as a prerequisite, as creating
the git-shell-commands directory allows interactive logins):
$ cat >$HOME/git-shell-commands/cvs <<\EOF
if ! test $# = 1 && test "$1" = "server"
then
echo >&2 "git-cvsserver only handles \"server\""
exit 1
fi
exec git cvsserver server
EOF
$ chmod +x $HOME/git-shell-commands/cvs
