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@domain.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-

The output would be too noisy on a large network. Few weeks ago I ran
Noisy only on the screen/email output. However, notice that *only* the
IP addresses found running Solaris telnet servers are written to the
results file ($0.results).
Perhaps we should change it to the following so that only one email is
sent with all the IP addresses found:
#!/bin/bash
# solaris-telnetd-audit.sh
IPSFILE="./ips.lst"; # file containing IPs to scan
MESSAGE="possible-Solaris-telnet-server-found";
EMAIL="youremail@domain.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 -p23 -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
P.S.: I personally like using genip
[http://www.bindshell.net/tools/genip] for generating lists of IP
addresses.
something that would go like this:
( echo "Sun bxes with telnet"; \
nmap -n -P0 -iL list -p 23 -O -oG - | \
grep -Ei 'Host.+open.+(Solaris|SunOS)' | \
cut -d ' ' -f 2 \
) | mail -s "Check those" unixadmins@example.com
