similar to: Non-interactive root access via hostbased using shosts.equiv

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

We have a problem using hostbased authentication in combination with the root account. We use hostbased authentication to hop from a 'management server' where we use strong authentication to several systems in a cluster. The management server is defined in shosts.equiv and the public key of this server is defined in ssh_known_hosts. This setup works for all users except for the root user

I'm not familiar with the use of .rhosts/.shosts, but I don't think those are needed at all with a machine or per-user known_hosts file/files

I'm trying to replace ssh 1.2.27 with openssh 1.2.1-pre* It seems that a openssh client accessing any openssh/ssh server I've setup always results in a password prompt. It also seems that a openssh server requires ssh clients to provide a password regardless of the entries in the /etc/ssh/shosts.equiv file. If I shut off the openssh server and run a ssh server then normal ssh client

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, I am still working on getting hostbased authentication working in OpenSSH 3.5p1. I emailed the user list, and got no response. It seems so simple, yet I have continued to have problems getting it working properly. I've read posts about it on this list, and the openssh-unix-dev list, and nothing I have tried seems to work. My question is this, does it matter which key, either

Hi, does anyone have any elegant solutions for managing shosts.equiv? In my puppet ssh module, host keys for /etc/ssh/ssh_known_hosts are automatically managed with: @@sshkey { $hostname: ensure => present, type => "rsa", key => $sshrsakey, } Sshkey <<| |>> Is there a similar construct 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: [...]

I''m trying to create a ssh class where the /etc/ssh/ssh_known_hosts and /etc/ssh/shosts.equiv stays updated. The issue i''m finding is that if I include a "tag == anything" in the Collector filter, it collects all resources EXCEPT it''s own. In this case, the known_hosts and .equiv files will have all the other hostnames, but not it''s own hostname.

Hi, I'm trying to figure out how to read OpenSSH's log files (to assist our people in diagnosing "why is it always asking me for passwords"). All clients and servers are 3.0p1. First: server does not have the client's RSA2 key in known_host. debug1: done: ssh_kex2. debug1: send SSH2_MSG_SERVICE_REQUEST debug1: service_accept: ssh-userauth debug1: got

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

Hello ! I think a problem was introduced in openssh-2.3.0p1 which is still there in the latest openssh-2.5.2p1. I just noticed it before my vacation and could not send this mail earlier than today. The problem is: You can't use the Rhosts-RSA authentication based on the hosts.equiv file and the host keys. The only possible way to do rhosts-RSA authentication is to allow the usage of the
