JSI Tip 7959. How can I send an email if an IP address does NOT respond to a PING?

I have scripted RUThere.bat to send an email to specified users if an IP address that you specify does NOT respond to a PING (Packet InterNet Groper).

The syntax for using RUThere.bat is:

[call] RUThere IPAddress Email [Email2 ... EmailN]

where IPAdress is the IP address you wish to ping, and EmailN is from 1 through N email addresses to notify.

NOTE: RUThere.bat uses BLAT, the freeware command-line SMTP mailer.

RUThere.bat contains:

@echo offif {%2}
