I see that support for AuthorizedKeysCommand has been added. The arguments supplied to the command is just the authenticating user. Can we add the SSH connection details (ie. source and destination IPs and ports) as well? This command seems to be the idea way of requiring one set of credentials from inside an organisation (say the user's...

Hi, I'm attempting to test the AuthorizedKeysCommand feature with the new port of ssh-ldap-wrapper to OpenBSD. I'm running yesterday's OpenBSD-current i386 snapshot, which includes AuthorizedKeysCommand. The port of ssh-ldap-helper (at http://old.nabble.com/-new--ssh-ldap-helper-td34667413.html) contains all the bits I need, and the individ...

Hi there, We could set AuthorizedKeysCommand script, this will allow only to replace authorized_keys file with keys stored in a database... But why this command is so limited? Why i can't just set a command script which will get a username and public key as arguments and let him do it's own authorization?? I think this will allow for...

Hi, I have a setup in which I run sshd as unprivileged user at dedicated port to serve specific application. It is working perfectly! One tweak I had to do, since the AuthorizedKeysCommand feature requires file to be owned by root, I had to use root owned command at root owned directory, although it does not add a security value. At auth2-pubkey.c::user_key_command_allowed2(), we have the following: if (auth_secure_path(options.authorized_keys_command, &st, NULL, 0,...

Hi guys, It might be nice if AuthorizedKeysCommand would receive the fingerprint of the offered key as an argument, so that programs like gitolite could implement more refined key-based identity lookup that offers better performance than AuthorizedKeysFile's linear scan. The following patch is untested but is the basic idea: diff -ru openssh-...

Hi all, I'm new to the list, so please forgive me if this is duplicated effort. I have created a patch for openssh which modifies the AuthorizedKeysCommand directive so that the incoming user's public key is sent to the specified program via stdin. This provides a means to identify the connecting user based solely on their public key and not just by the username. The inspiration for this was to be able to provide a service similar to GitHub or B...

Hi Using SSH_ORIGINAL_COMMAND in AuthorizedKeys is so helpful, I'd like to know if it might be possible to access it in the AuthorizedKeysCommand context (via env ?). Is this possible ? can anybody give me advice on going into this ? If possible, I'll use this SSH_ORIGINAL_COMMAND to send client specifics information to the AuthorizedKeysCommand script. Currently, the only alternative to this is to use the login itself (we have around...

Is there any way to make the AuthorizedKeysCommand as the user which is trying to log in? Thanks. -- Yves.

Hi, I've been kicking this idea around, and the problem with it escapes me. I'm looking for someone to tell me why this is a bad idea. The new OpenSSH includes the AuthorizedKeysCommand, which was mostly added to let people use a command to look up user keys in LDAP. LDAP key lookup have some limitations -- specifically, the common openssh-lpk_openldap schema won't let you add restrictions at the front of the key. This didn't matter so much when the LPK patch was such a p...

...ent it the way it currently is? Currently it executes one external command per auth request. If we would like a larger scale support, we would need to make it configurable to support one external command execution per presented pubkey (user may present multiple pubkeys, of course). Something like: AuthorizedKeysCommand "/path/to/auth %u %p" # %p is made up, but it stands for pubkey fingerprint b.
