@deed: I dont think ssh sessions can be shared.
I use rsa keys with passwords, and would LOVE to have a question popup asking the password for the key. Could also be implemented to ask password if you do not use a key (you should).

Thanks for your commments deed!
In addition, for security reasons openssh-client doesn't allow sending the password as a command line parameter/enviroment variable etc. so the program can't tell it to ssh.
But, in fact there is an undocumented way you can use URPO with password :
1. start it from xterm
2. leave the sshkeyfile empty in settings
3. Press connect
4. Switch to xterm and give the password (you have 15 seconds before the timeout
(Longer timeout when sshkeyfile is empty is now added to todo list, and will hopefully appear in the next release, whenever that comes out...)
As for your other request, I think exuvo is right: there probably is no way to capture an existing SSH connection.

Wouldn’t it be easier to simply ask the password like any xterm ssh connection? or at least the ability to choose in the setting between a key file and a password request?

Thanks to you two for those valuable information.
In fact, the undocumented way to use URPO presented by helihyv did the trick and that is great, exactly what I wanted!
I didn't knew for "Maemo5 does not support asking password in graphical environment" and so let's go with the xterm way...
@exuvo: You're right, I should use a key, and in fact I do it for security matter in certain circumstances, but thinking about printing (not so often) from the N900, to a (random) machine with cups and a printer attached, I find it easier (quicker) with the askpass method.
Thanks to devs for this now much more useful tool, My vote for competition will go for it ;-)

The workaround you provided is agreeable but I would like to share a hack that will allow you to overcome ssh "limitations" (read security features). The trick is to use "empty" command. Sources and examples showing how to use it within scripts can be found at empty project homepage.

Thank you. I'm not a unix/linux user. Could you show one example of how to print a file using URPO/terminal/empty?

Thanks for all comments. Nice to hear that there is need for a program llike URPO.
(1) Password authentication. I will try some tricks to allow password authentication in next release. It is not the right way, it is unsecure etc.. but can be useful in many situations.
(2) Windows printing. URPO just needs CUPS and Linux (*nix ...) computer!
URPO works in very simple way: first copy file to Linux remote computer, then use CUPS printing command in remote computer to print it (and delete this temporary file). Printing to Windows host needs samba protocol client and driver information...
I guess email printing in some new printers / web-based printing will be a useful solution in some day. CUPS may be a too heavy printing solution to be ported into N900.
[By the way, it is possible to use a printer connected to Windows computer, if you have a Linux computer, too, and set up your CUPS to use Windows printer through SAMBA ]

EDIT: *Cough*
CUPS is the standards-based, open source printing system developed by Apple Inc. for Mac OS® X and other UNIX®-like operating systems.

/Users/NICK/.ssh/authorized_keys/: Is a directory

Anyways, I'm having some trouble in here now. I can't send the damned RSA via SSH, haven't tried though Bluetooth yet. I do manage to make the connection but every time I do it, the X-Term only printsand I fail to receive the file.Code:/Users/NICK/.ssh/authorized_keys/: Is a directory
Like this:
cat ~/.ssh/id_urpo | ssh user@computer 'cat >> ~./ssh/authorized_keys/id_urpo'
I started this new thread because I did not found a specific URPO one, so mods, move it if needed.
I've been testing this app and must say that it can be very useful. I like the idea of being able to print on any cups system connected printers as I work in full *nix environment.
By the way (sorry for that!) I dislike a lot this setting that required an ssh key file, and that need to be upload on each and every computer you want to print through. This is a boring process!
Wouldn’t it be easier to simply ask the password like any xterm ssh connection? or at least the ability to choose in the setting between a key file and a password request?
Another thing is that if you are already connected to the named computer with an ssh connection, why URPO can't detect it? Why does it still ask you to connect when you are already? Couldn't it start, detect that you are already connected, and use this established connection, or ask if you want to use it.
Anyway, thanks to the devs for this beautiful idea that can become a great app.
