Default Using multiple BSDs: How have you implemented them?

Since it is still not completely finished- see the mailing lists for more information- I decided to use the FreeBSD G3 and an OpenBSD i386 install together. The G3 acts a s a viewer/thinclient and the P4/i386 acts as a server. I haven't quite gotten the ssh and X11 forwarding setup.
What ways did you setup different BSDs to work together?

It should be no problem getting X11, OpenSSH, and most other programs working together with various operating systems (Including FreeBSD & OpenBSD).

Xorg is still Xorg no matter what OS it runs, the same applies to OpenSSH and most other applications. While details, versions, and default configurations may be different, it is conceptually the same.

If you want a more specific answer regarding your X11 forwarding: Ask a more specific question

Right now, I'm at the "I don't understand this quite enough" point.
OpenSSH is at the point of not exporting keys properly.
X11 forwarding is at the point- A strange way to be.- of which .Xauth and how?

I've kept the experimenting on the FreeBSD x86 install with the host and jail.
(The fear that a clusterf* will ensue- by reason of me- is enough for me not to want to mess up the G3 or the OpenBSD install.)

What I'd like is SSH with X11 forwarding- and maybe on another display; but, what I'd settle for- and am right now- is the VNC setup.

I have setup an rsa key on the openbsd machine and will setup another on the G3 later.
Here are the questions:
It's a LAN behind the router and the machines have an assigned IP address.

Do I need to use a command such as scp to the name of the machine or to the assigned IP?

Let me know what work I need to show.

If you want to copy files between machines using hostnames, then you will need to set up DNS or set the appropriate entries in the hosts(5) file. And if you think about it, what DNS (or the hosts(5) file) is doing is figuring out what IP address matches the specified hostname.

Otherwise, you can specify each machine by IP address when copying files about.

I get the following error:

Code:
debug1: Roaming not allowed by server
It then refuses to connect.

On both machines I have set: port to a higher number, user only has ssh access, X11 is forwarded.

Did you set up both the ~/.ssh/authorized_hosts and ~/.ssh/id_rsa (Your public and private key) on both machines?

I've exported the key from Open to Free.

Code:
$ ssh -p 2442 -Y moleque@192.168.1.3
Permission denied (publickey,keyboard-interactive).

I'm having a problem with host key importing/exporting.

Code:
$ uname -a
FreeBSD tima.tiza 9.0-20100418-SNAP FreeBSD 9.0-20100418-SNAP #0: Sun Apr 18 06:51:02 UTC 2010     root@dynode.isc.freebsd.org:/usr/obj/usr/src/sys/GENERIC  powerpc
$ ssh -Y -p 2442 moleque@192.168.1.3
The authenticity of host '[192.168.1.3]:2442 ([192.168.1.3]:2442)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes

$ ls
known_hosts		moleque@192.168.1.3
$
I'm putting the information down because something is escaping me.

I could be wrong but IMHO you probably have copied the keys with
Code:
$ scp id_dsa.pub moleque@192.168.1.3
That creates a local copy of the id_dsa.pub file with the name of moleque@192.168.1.3

In http://www.daemonforums.org/showthread.php?t=1758 I give a correct way to append a public key file to the .authorized_keys file.

This would seem to indicate that your key is not being accepted for some reason.

Do you want to use a RSA or DSA key? You have both, choose one and remove the other, it will serve no puropse other then make things more complicated.

Are your authorized_hosts and id_rsa/id_dsa (As mentioned above, choose one) *exactly* the same? Check with md5 to be sure.

I've recreated the keys a few times.

Did you verify that both keys are the same as I mentioned before? I know you *think* they are the same, but that is not the same as *knowing*.

No. They don't match.

I'm getting the same result after following J65nko's howto.

The power here has gone out twice; so, I have no idea what the set of commands were to setup login from X.5 to X.3.

Edit: the problem is in the OpenBSD conf files.



Now, how do I disable the keyboard and publickey checking?

The /etc/ssh/Known_hosts file on the OpenBSD is empty while the G3 has the host, port, and key.

Right, so for some reason something went wrong while copying the files.

I would take the easy way out: Copy the files to a USB drive, floppy disk, whatever, and copy them that way.
Make sure you copy right *right* private/public keys.

I have the FreeBSD to FreeBSD ssh setup going good.
I still need to see what went wrong with the FreeBSD to OpenBSD login.
