similar to: OpenSSH Hostbased authentication HOWTO

Hi, I have found a general way to configure hostbased authentication using OpenSSH on several , ( I created a howto about it at http://www.omega.telia.net/vici/openssh ) but there is one remaining problem which I still could not solve. I would like to make hostbased authetication work without DNS resolving available both on the server and client side. First I added the IP addresses to the

Hi, I setup two sshd instance (using OpenSSH_3.5p1 bins on redhat7.2 kernel 2.4.20-19.7smp ) in order to achieve differnet sshd settings (e.g use different auth.method) on two different network interfaces (both on port 22). For example to setup Hostbased authetication on the 1st sshd and RSA pub. key auth. on the second: The 1st instance config file /etc/ssh/sshd_config looks like:

Hi, I use openssh version: OpenSSH_3.7.1p2, SSH protocols 1.5/2.0, OpenSSL 0.9.6l 04 Nov 2003 (complied by myself) on redhat7.2 ( kernel 2.4.20-19.7smp ) It seems that sshd returns vith wrong returns value, if some other process (e.g. another sshd) already reserved the given IP address and port. I setup two ssh daemon almost with the same settings in order to listen on two different IP

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

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

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: [...]

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, 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

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.

I am seeing the same issues as another recent post, hostbased authentication in 3.4p1 not seeming to work. I tried the ssh-keysign.c patch posted, didn't seem to fix the problem.

Hi, is there any way to use hostbased authentication without the need to have the SSH host keys stored in a known_hosts file? We run a large cluster where we need to have passwordless remote login available. We currently do that with hostbased SSH authentication. But it is error-prone and a lot of work to keep the known_hosts file up to date on all hosts. (This is the same situation like DNS vs
