How to grant access to an ssh tunnel to access svn but not the shell

Question

有没有一种方法可以授予Linux用户的访问权，使其通过ssh隧道连接到svn而又不授予该用户对Shell的访问权？

Answer 1

If you use private/public key authentication, thats rather easy. You can specify the commands that a user authenticated with a specific key is able to execute, so he can only execute svn related commands.

Have a look at these:
