similar to: Connection info with AuthorizedKeysCommand

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

I read an article today about keyboard interactive auth allowing bruteforcing. I'm afraid I have minimal understanding of what keyboard-interactive really does. What does it do, and should I have my clients set it to off in sshd_config? --- Scott Neugroschl | XYPRO Technology Corporation 4100 Guardian Street | Suite 100 |Simi Valley, CA 93063 | Phone 805 583-2874|Fax 805 583-0124 |

Hello there, I am having trouble connecting to a ssh server installed with openssh recently. I have posted about the problem on Superuser, and I will repost a description of the issue below. If anyone here is able to rescue me from my deep well of ignorance, I will be very grateful. http://superuser.com/questions/1094734/ssh-automatically-disconnects-after-login I'm trying to set up an ssh

Oops. That's -T.

I used the latest version from here: http://www.mls-software.com/opensshd.html On my other (Windows 10) machine (on which openssh works), I have cygwin installed, but if ssh was using cygwin, I wasn't aware of it. I just ran ssh from the command prompt. Wallace Forman 913-669-4453 On Wed, Jun 29, 2016 at 4:37 PM, ?ngel Gonz?lez <keisial at gmail.com> wrote: > On 29/06/16 21:36,

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 much more powerful tricks. For example do to an

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

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 just commited the patch on https://bugzilla.mindrot.org/b/1663 It adds an AuthorizedKeysCommand option to sshd_config to use helper program to fetch a user's authorized keys. Quite a few people have asked for this to allow storage of public keys in LDAP or other databases. The program is executed (directly, not via the shell) with a single argument of the user being logged in. It

Hi everyone, I know scp is kind of the red-headed stepchild of the suite, but I'd like to propose an extension to the syntax for remote-remote passthrough using the "-3" option. Currently the syntax is essentially scp -3 [ -P port ] [user@]host1:file [user@]host2:file This is great, as long as both remotes are on the same port. It causes difficulties if host1 and host2 are not

Hi SSH-devs, This may be a bit off topic for this list, but.... Would it be ok to share a private key in an installer script so long as the corresponding public key is setup like this... command="cat ~/.ssh/id_rsa.pub" ssh-rsa AAAA... I'm looking for a secure way to get a user to share their public key through SSH which can be invoked from an installer on another host...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

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

Hmm... Perhaps not. Is something like cygwin required for it to work?
