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

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

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

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,

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

Dear All, I am trying to use the hostcertificate to do the hostbaed authentication with the steps in the regress/cert-hostkey.sh But it seems that it can not login with the hostcertificate.: Here is debug message from the ssh client : ssh -2 -oUserKnownHostsFile=/opt/ssh/etc/known_hosts-cert \ > -oGlobalKnownHostsFile=/opt/ssh/etc/known_hosts-cert sshia3 -p 1111 -vvv debug1: checking

All: I have a problem connecting Openssh 3.0.2p1 on Solaris 8 using hostname authentication for non-root users. When I connect to the sshd from a second machine as root it works fine using HostbasedAuthentication, but it always fails with non-root users. I suspect that I am having a permissions problem somewhere, but I'll be damned if I can figure out where. Any and all help

I'm trying to use HostbasedAuthentication. Running ssh -v -v -v user at host the following error occurs: debug3: authmethod_is_enabled hostbased debug1: next auth method to try is hostbased debug2: userauth_hostbased: chost <host> debug2: we did not send a packet, disable method What does this mean ? I enabled HostbasedAuthentication in /etc/ssh/ssh_config and as it looks, this setting

Hi, I'm experimenting with host certificates in 5.4p1 and seem to have hit a usability issue. I've generated a host certificate, added the HostCertificate option to the sshd_config and restarted sshd. I've replaced the system's ssh_known_hosts file with one that has a single entry of the form: @cert-authority *.example.domain ssh-rsa ... This works provided that I use the

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
