thanks for the reply....i've read the info form the link you send and i do understand it, but there's another problem...it seems that i can't install absolutly nothing and acording to you instrucction i have to install OpenSSH (client and server) but my application manager shows this message:

Unable to download openshh.
aplication package not found.

i also tried downloading the file from maemo first and then use the apt-manager to install it but the same, the other thing that happens is that it shows the "preparing for instalation, please wait" window and it keeps loading and after a long time it show the same message.

so i try to update it but the application manager's log shows:

hildon-aplication-manager 2.1.16
apt-worker: terminating 1885 to get lock
E: Failed to fetch http://catalogue.tableteer.nokia.com..././Release.gpg Could not...

i have the "Nokia System software Updates catalogue" and "maemo extras catalogue" enable, but the log show a message next to both that says "failed to update".

any new suggestion?
