Hi Sabahattin,

Yes, interactive actions are problematic.  Many System Prefs are configurable 
via the command line though, so I often ssh in as root and set things that way. 
 Are you positive that the Server app will not update using the SoftwareUpdate 
tool through ssh and in as root?  My readings tell me otherwise although I 
can't recall for sure if Server app was updated last time I did things in this 
manner.  I, too, usually have a keyboard connected but have done things 
remotely using ARD's Control feature as well.

For the Server app, as you likely already know, once the Server app has been 
updated, it needs to be ran again to re-setup services.  In ARD,   keyboard 
strokes will be passed through as long as you don't hold down VO keys.  So, in 
ARD, check which app is open, if it is at the Login screen, take control of the 
Server, press the first letter or two of the user you wish to login as, press 
return, enter the password and press return again.  You can check on if it 
worked by going out of control mode and seeing which app is active, it should 
be Finder if the login worked for you.  Sometimes, you need to press down on 
the mouse or trackpad once to get focus to the Login screen app if the above 
didn't work for you.  Once in the Finder, you can use the "Open Application" 
item under the Manage menu to open the Server app which will bring up the 
"Which Server do you wish to play with" dialog.  By default, it's focus is on 
the current server, so pressing the return key continues on to the next screen. 
 Press return again to agree to everything since, of course, it's your own 
server.  The next dialog asks for your Admin password, enter it and press 
return and the re-configuration of services will proceed on its own I just let 
it do its thing for a few minutes, then press cmd-q to quit the Server app, 
cmd-option-shift-q to log it out and then close the control screen to bring 
focus back to my workstation.

Just for fun, I've sat next to the Server with my laptop and performed these 
actions to see if it was working properly, and it works as I've outlined.  
Using this method, you can turn VO on or off on the Server, can use ctrl-f2 to 
get up to the menubar, ctrl-f8 to get to menu extras and more.  Of course, 
there's no audio feedback, so you need to have faith in your memory.  
Sometimes, though, I actually get out of my chair and walk to the other end of 
the building or wait until the next day I'm at one of the other facilities to 
sit in front of the Server to do what needs done.

Later...
