[Xitami] RE: Stopping and restarting (or resetting) Xitamiwithperl

[MRJ InfoTech Admin]

If and as long as you run two processes there is no problem.

1) Your CGI application to execute a call to an application in your server 
machine
2) The Application which is invoked by the CGI.

The CGI is only to send some parameters to the main Application to indicate 
what you want it to do.

A proper set of rules for this would be as follows

    Halt server
    Start Server
    Reboot PC

The fourth optional parameter I am toying with now since I keep having 
problems keeping Xitami alive
since FTP keep hanging up with nasty C errors is a checker that can lay 
dormant in the background
and run a check every 30 seconds to ensure that Xitami is actually up and 
running.

The reboot PC I made into a CGI to force a full system flush at a set time 
every night.
If I miss to log in and run it, It will run itself by the Scheduler to 
force a flush of the system.

Since Xitami can be set to run on boot up, this is not a problem either.

Further more, if your config is ok, and you execute a cgi to reset your 
machine, you can just as
well do this from the cgi if you have another app restarting it again.

I dont see any problems whatsoever with this and in fact wrote my solutions 
in VB 5 to keep it simple fast and practical.
