# Jabber-SH — SH console via XMPP/Jabber (GTalk) | |

# Jabber-SH allows you to administrate a remote computer via a command line | |
# through a Jabber client. It’s like SSH via GoogleTalk! :) | |
# This is just a hack but it might be usefull sometime to run basic commands | |
# on a machine that is not accessible via ssh. | |
