I don't think you should care about that, just use:
username-a: "my_string"
username-b: "my_other_string"
call (reform [ "ssh" username-a   mycommands etc] )

However ssh stores files in 
~/.ssh/authorized_keys

See http://support.suso.com/supki/SSH_Tutorial_for_Linux

The public keys are stored in $HOME/.ssh/authorized_keys for the 
respective users

Key-based SSH authentication is most convenient when used in combination 
with an "ssh agent" that holds the private keys and (temporarily) 
stores their passphrase

You can then just load multiple keys into your SSH agent, and all 
of them will be tried for authentication

So, as Max says, no need to associate usernames with keys in that 
keys (besides setting up $HOME/.ssh/authorized_keys correctly)

Ok, thanks. So do you know a SSH agent for OSX? Or is there a standard 
SSH agent CLI tool?

the osx keychain should work for you

Ok, giving all this a try and let you know :-)

When I have setup a portforwarding via SSH, how can I get rid of 
it?

And some more questions: I have a server that listens on port 44000 
in a VM. The VM is using NAT network. The VM NAT router is configured 
to forward port 44000 from the outside to the VM IP on port 44000.

When I use telnet localhost 44000 on the system the VM runs I get 
a connection but the listening server doesn't recognizses it as a 
connection.

When I use: ssh -L 44000:192.168.22.1:44000 [user-:-my_vm_server-:-com], 
from a remote machine, the SSH tunnel is setup and the login is done 
on my_vm_server.com

When I use telnet localhost 44000 from my_vm_server.com than, the 
connection is done and the listen server recognizes it.

When I use telnet localhost 44000 from the remote machine, which 
should tunnel through the SSH channel and forward to 192.168.22.1:44000 
on my_vm_server.com, I get a connection but the listen server doesn't 
recognize it...

Any idea, why the TCP/IP connections from the remote machines are 
not recognized?

When I have setup a portforwarding via SSH, how can I get rid of 
it?


Close the SSH session or, if using OpenSSH, use ~C to enter the client's 
command-line and remove the (remote) forwarding with -KR<port>. You 
can't remove local forwardings this way, afaik.

Ok, thanks.

The latest version of REBOL/View does NOT run on Ubuntu 11 Beta. 
I've tried it on two different machines. You get the old "Bad face 
in screen panel" error.


Does anyone have any ideas about what may be the problem? Ubuntu 
10.10 is fine.

could it be no x11 installed ?

Ubuntu is going to introduce Wayland, a replacement for X11, but 
from what I'm reading it shouldn't be default in 11.04

I'm running Ubuntu Desktop. I've tried it on two laptops -- both 
with and without Unity.

did you check libraries?

ldd

might also just be missing bitmap fonts.

I'll look into it. Thanks.

Distributor ID: Ubuntu

In plain English: /View 2.7.8.4.2 works fine (for me) on Ubuntu 11.04.

(u dont really have to say copy from the console)

So I'd say the problem seems to be nothing intrinsic to REBOL, but 
probably something related to missing libraries.

Confirmed, it doesn't work, even adding all dependencies:
libc6
libstdc++6
libx11-6
libxcb1
libxaw7
libfreetype6
libext6
libxt6
libxmu6
libgcc1
libsm6
libice6
libxpm4
zlib1g
libxau6
libxdmcp6
libuuid1
Do I missed any dependecies?

It appears in the console:
** User Error: Bad face in screen pane!
** Near: size-text self
so I think that it''s internal to Rebol...

4.3 or 4.2?

MaxV: that bad face error message happens when u r trying to start 
a rebol/view without an actual x11 server. i was trying to trick 
it with xvfb and xvncserver but no luck

install xfonts-100dpi and xfonts-75dpi and the problem should be 
gone

max, you can add those to your dependency list

(and you'll most certainly have to re-login to your x session after 
installing those packages.)

i was even trying ssh -X from a linux box but it didn't help either.

install the bitmap fonts and you'll be fine

Andreas: but r u talking about starting /view on an actual X11 server? 
or is it possible to start it without a real X11 head?

x forwarding (ssh -X) certainly works

xvfb should work as well, but i haven't tried it in ages

in both cases, you'll need the bitmap fonts installed in the respective 
x server

yes, xvfb works fine:
$ xvfb-run ./rebol -qsvw --do "print [system/version view?]"
2.7.8.4.2 true

SOLVED!!! Added dependecies xfonts-100dpi and xfonts-75dpi !!!! Thank 
you very much Adnreas!!!!!!!!
You can download last linux packages from: 
http://www.maxvessi.net/rebsite/Linux/

If you use the linux packages, all dependencies are automatically 
downloaded!!!

Max, have you looked into what would be required to get a proper 
repository for R2 and maybe R3 set up in multiverse?

tested :  installation ok

I'm working to put in it on Launchpad
