It appears that /etc/ssh/ssh_config enforces policy on local users in addition to its documented role as provider of defaults. $ ssh -V OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f $ cat .ssh/config Host localhost HostbasedAuthentication yes PreferredAuthentications hostbased $ ssh localhost Hostbased authentication not enabled in /etc/ssh/ssh_config ssh_keysign: no reply

The problem I am seeing was introduced between 6.4p1 and 6.5p1 (and still exists in 6.6p1). With HostbasedAuthentication/EnableSSHKeysign turned on, I am seeing one of two sets of messages: no matching hostkey found ssh_keysign: no reply key_sign failed and not a valid request ssh_keysign: no reply key_sign failed Then in either case two password prompts: bowman at HOST.math.utah.edu's

Hi All. While working on something I noticed a regression failure on Solaris 8. It turned out to be present in -cvs and wasn't due to my changes. One of the tests that fail is basically: ssh -2 -F $build/regress/ssh_proxy 999.999.999.999 true The server reports: sshd[20529]: Disconnecting: Command terminated on signal 11. The culprit seems to be session.c line 1019 or so: snprintf(buf,

The latter versions of openssh (3.4,3.5 and 3.6.1) all seem to suffer from a broken ssh-keysign binary. This causes HostbasedAuthentication to fail. We have installed 3.6.1p1 on a Solaris 8 machine using openssl-0.9.6i. This fails thusly ssh server <......some \digits removed - a key perhaps?> ssh_keysign: no reply key_sign failed a at server's password For version 3.4p1 we patched

Maybe I just can't read properly, but I just spent the best part of a day trying to work out why HostbasedAuthentication wouldn't work for me (with protocol 2 in openssh-2.9p1). It seems (though maybe there is something wrong with my install), that after enabling it in the sshd_config it doesn't work, since the client will not in fact request it (by default). I was fooled by the

Greetings, For those interested in using certificates with hostbased authentication, I have just submitted an enhancement request[1] to the OpenSSH bugzilla site with a preliminary patch that adds support for this. Despite the fact that hostbased authentication is, by default, disabled for both the client and server, there are environments where hostbased authentication can be very useful. One

My keys are secured with a passphrase. That's good for security, but having to type the passphrase either at every login or at every invocation of ssh(1) is annoying. I know I could invoke ssh-add(1) just before invoking ssh(1), if I keep track of whether I invoked it already, or write some hacky scripts; but the rest of OpenSSH is wonderfully usable without any hacks. Hence, this patch.

How do you enable hostbased authentication in OpenSSH? I have two Red Hat 7.3 machines running openssh-3.4p1, and I would like to be able to ssh from either of the machines to the other, as any user, without using passwords or per-user keys. My /etc/ssh/sshd_config contains: [...] IgnoreRhosts no HostbasedAuthentication yes [...] My /etc/ssh/ssh_config contains: [...]

Hello, I've troubles getting the hostbased method to work. I've given up on system-to-system for now (different versions), and I'm just trying to debug localhost. As far as I can see, the key is accepted, but then a sudden "Failed hostbased" is returned: [...] debug3: mm_answer_keyallowed: key 0x8099bc0 is disallowed debug3: mm_append_debug: Appending debug messages for

Hi, we're looking to reduce the number of host lists that need to be kept in sync in our system. (There are quite a few of them all over the place) OpenSSH CAs are an obvious solution for not having to keep all host keys in sync in /etc/ssh/known_hosts, however, while OpenSSH does support using a CA in conjunction with hostbased authentication, it still requires a list of all authorized

Hi, We want to use Hostbased Authentication in OpenSSH 3.4p1 completely based on rhosts or shosts. Don't want to have any keys exchange between server and client. Created /etc/ssh/sshd_config on OpenSSH server with: RhostsAuthentication yes IgnoreRhosts no HostbasedAuthentication yes Created /etc/ssh/ssh_config on client with: Host * HostbasedAuthentication yes Created /etc/rhosts.equiv,

Hi, Based on some experimentation with 5.4p1 and a cursory examination of the source code, it doesn't look like hostbased authentication takes advantage of certificates other than to authenticate the server. Is that correct? In cluster environments, hostbased authentication is still useful but the size of the ssh_known_hosts file can become unwieldy in large clusters. As an example, a few
