Redirecting Users to New Server
I am new to shell scripting. I urgently need a script on a backup server that will ping the main server to check if the server is up. If the main server is down- the script should transfer the IP of the main server to the backup server. Once the main server is up again the backup server will release the IP so that traffic will go back to the main server. The script should run as a background daemon.

utmpdump
UTMPDUMP(1) System Administration UTMPDUMP(1)
NAME
utmpdump - dump UTMP and WTMP files in raw format
SYNOPSIS
utmpdump [-frh] [ filename ]
DESCRIPTION
utmpdump is a simple program to dump UTMP and WTMP files in raw format, so they can be examined. utmpdump eads from stdin unless a file-
name is passed.
OPTIONS
-f, --follow
Output appended data as the file grows.
-r, --reverse
Undump, write back edited login information into utmp or wtmp files.
-h, --help
Print a help text and exit.
-V, --version
Output version information and exit.
NOTES
utmpdump can be useful in cases of corrupted utmp or wtmp entries. It can dump out utmp/wtmp to an ASCII file, then that file can be
edited to remove bogus entries and reintegrated, using
utmpdump -r < ascii_file > wtmp
but be warned as utmpdump was written for debugging purpose only.
BUGS
You may not use the option -r as the format for the utmp/wtmp files strongly depends on the input format. This tool was not written for
normal use but for debugging.
