Send message after server reboot

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Please advise if this is possible in a Perl script??
Here is what I use to find out when my Solaris 7 server was last rebooted:

Unix# psrinfo -v
Status of processor 0 as of: 03/07/02 12:59:02
  Processor has been on-line since 01/23/02 12:23:27.
  The sparc processor operates at 50 MHz,
        and has a sparc floating point processor.

But I have to be root to do this. Is there anyway (after the Solaris 7 server is rebooted) to email me and let me know it was rebooted. I want to put this in a cron job to check just once a day and only email me if the server was rebooted. Also I am hoping I wont need root priviledges to do this.

The best way would be to add it to the system start up script. /etc/rc.d/rc.local or something of that sort. If you can't do that, then you can go the cron route. Linux (don't know about Solaris) has a command called 'last' that will have a line that shows when the system was rebooted. You can narrow the last output by the user which under Linux is 'reboot'. So 'last -1 reboot' would give you the last time the system was rebooted. The other thing you need to do is keep track of the last reboot time that a notification was sent for, so that you don't double send.

Well, there are a couple of things you could do. You can talk the sysadmin of the box into putting a script in the startup routine to send an email, or you can do what you suggested and run a cron job and have it send an email. Either way, look into Mail::Sendmail. As for system commands, a simple command like `w` or `uptime` will report uptime. You could get the outout with backticks and parse out the uptime. If it is less than a day, send you the email. Good luck Scott	[reply] [d/l] [select]
