RE: RE: [cobalt-users] Planned execution of a script on a RAQ - AT not there ?

[Pizza Box manager <cobalt-list@xxxxxxxxxxxxx>]

Thank you for all the interesting tips and information;
On that RAQ 550 I found ntp was not running, not sure why. Started manually 
now.
What I had in mind was the AT command, commonly found on other Linux boxes, 
but not here on that RAQ550.
I will however use a daily cronjob and shut it down after it's been used 
once on the required day.
The job to is is a sending of a few emails (maybe 30), however it must be 
the most precise job I have found, because the order in which these emails 
are received will determine who "wins". It's basically a first-come 
first-served competition, with the registrations being accepted from a 
precise time on the hour - say 11:00 am.
Currently the emails are prepared as TXT files, and stored in a directory. 
A Perl script is called in my cronjob and fires them up. 
(/root/cronjobs/scripthere.pl)
The emails are short 4 kb text files, almost the same but for the 
customized names etc, as they are based on templates.
We are using a "source" server that is as close to the destination server 
as possible (same city).
How should I name the script or what should I do to give it absolute 
priority, as unfortunately it is a precise 00 mn) hour and I'm afraid the 
RAQ will do other things at the time (logs rotation ?). Could the emails be 
in the queue already and be sent out at the required time ?
Because I need the destination server to receive these emails as close to 
11:00 but not before (else invalid entry !), I guess I should send a bit 
before the given time...Flooding the destination target is not allowed, 
would be stupid, and would get us banned, but I guess we may opt to send 
once a few seconds before, once on time, and once a few seconds after the 
crucial deadline...
Thanks a lot for your time and consideration,
