Hi,

you dont want to ask nmap to determine the OS based on port 23 scan only.
so, s/p23// in the second nmap call.
hence:

#!/bin/bash

# solaris-telnetd-audit.sh

IPSFILE="./ips.lst"; # file containing IPs to scan
MESSAGE="possible-Solaris-telnet-server-found";
EMAIL="youremail@...ain.tld";

for IP in `cat $IPSFILE`
do
        echo "Trying $IP ...";
        if nmap -P0 -n -p23 -sS $IP | grep -i open > /dev/null
        then
                if nmap -P0 -n -sV $IP | grep -ie 'SunOS' -ie
'Solaris' > /dev/null
                then
                        echo "$MESSAGE -> $IP"; echo $IP >> $0.results;
                fi
        fi
done

cat $0.results | mail -s $MESSAGE $EMAIL



my 0.02$

Cheers,

endrazine-
