cron, remote execution


Recommended Posts

Like a lot of people, I want to schedule Retrospect

 

backups using "cron". I have encountered one little

 

problem though ...

 

 

 

If I am logged in at the terminal of my XServe,

 

the cron-scheduled Retrospect job runs fine. You

 

can even watch the Retrospect GUI display go

 

through its paces if you're bored.

 

 

 

However, if I'm not logged in at the terminal,

 

Retrospect fails to start. To try to get a bit more

 

information, I tried running a Retrospect run document

 

from a remote login shell, e.g. something like

 

 

 

prompt> open goBackup

 

 

 

which failed with the following error message:

 

 

 

kCGErrorIllegalArgument : initCGDisplayState : cannot map display interlocks.

 

kCGErrorIllegalArgument : CGSNewConnection cannot get connection port

 

INIT_Processes(), could not establish the default connection to the WindowServer.Abort

 

 

 

... so I guess the problem is with the display.

 

I'm new to Retrospect and Mac OSX, so I could do

 

with some help!

 

 

 

Anyone who can help me out will be treated to

 

a pint of the finest local ale on me, next time

 

you're in Edinburgh :)

 

 

 

Thanks

 

Brian
