[X-Unix] enable remote desktop from CLI

[Giovanni Cutolo]

Hi,

I have a G3 iBook with MacOSX 10.4 whose video board is as good as 
dead. So, there is no way to use a monitor (built-in or external) with 
it.  What I would like to do is to use the iBook remotely from another 
computer in my LAN.  The only problem, I suppose, is that remote 
desktop (as well as remote ssh login) were disabled when the iBook 
crashed.
I am able to switch the iBook on, log in and open the terminal, where I 
can effectively issue commands. (I am sure that this is working:   I 
can see the iBook hard disk from remote, so I can test that commands 
like creating a file do actually work.)    Does anybody know what is 
the command to activate remote desktop or remote (ssh) login from the 
terminal?  I suppose some defaults xxxx would do, but I would like to 
know before going to the try -with-finger-crossed stage.

Thanks a lot in advance.
