I want to extract three substrings from this and the o/p should be like this.
66.249.73.11 IMBOSS=Z05 81.104.178.164
The first one is the IP address and the second is a string as "IMBOSS=some value" (this can be anywahere in the log file, the script should just search and extract) and then finally an ip address which is normally at the second last position. I have marked the required strings in the o/p in red color.
It would be a great help if someone can help me here.

logsave
LOGSAVE(8) System Manager's Manual LOGSAVE(8)NAME
logsave - save the output of a command in a logfile
SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]
DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will
also be written to standard output.
If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
logfile
logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to
/var/log.
OPTIONS -a This option will cause the output to be appended to logfile, instead of replacing its current contents.
-s This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console,
while not being written to the log file.
-v This option will make logsave to be more verbose in its output to the user.
