In general, do things remotely through SSH is exactly like when using the terminal noramlly. You enter the same commands, in precisely the same way. So if for some reason you don't use mikkyo's script, although I recomend you do, you can use
<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
java -Xms300m -Xmx300m -XX:NewSize=100m -XX:MaxNewSize=100m -cp Agent.jar ubero.agent.Agent -text </font>[/code]
to startup Ubero using the CLI. That's using the memory tweak. You can decrease the tweak by replacing 300 and 100 with smallers numbers.
I still recomend using the script and using
<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>./uberorunner </font>[/code]
to start the whole thing going.
