similar to: [Bug 2367] New: AuthorizedKeysCommand add key fingerprint as second argument

You really don't need openssl for that. And the fingerprints are simple. Here is a python script that do the same as ssh-keygen -fl /path/to/key : #!/usr/bin/env python3 import binascii import hashlib import sys if __name__ == "__main__": key = binascii.a2b_base64(sys.argv[1]) if sys.argv[2] == "md5": m = hashlib.new("md5")

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-6.2p1/auth2-pubkey.c

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

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

Hello, Currently OpenSSH has a fixed order on how the key authenticates the user: at first it tries to authenticate against TrustedUserCAKeys, afterwards it does it against the output keys from the AuthorizedKeysCommand and finally against the files as set in AuthorizedKeysFile. I have an use-case where this order is not ideal. This is because in my case the command fetches keys from the cloud

Hi, is there a particular reason why this feature is "user" based and not "user-pubkey" based? What I mean is that it works for installation with small number of pubkeys per user. But imagine i.e. a GitHub scale - all users logging in as user "git". On each auth request all the keys from database would be fetched and feeded to OpenSSH. Now I am only asking this out

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 individual pieces appear to work once configured:

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

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

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 own authorized_keys file) and another set from outside

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

I'm running into issues with AuthorizedKeysCommand when the sum of the size of the public keys become bigger than ~ 12 KB. I created a bash script that runs #!/bin/bash curl -s --compressed http://someurl.example.com/pubkeys/$1 and am getting "error: returned status 23".
