Hello,
I am responsible for monitoring hundreds of machines
over thousands of
external IP addresses. I currently run nmap manually
once a week and import
the results into Excel to compare them with the
previous week to find hosts
that are new and also take note of those that have
been taken off the
Internet. I am looking for a web front end, batch
process, or similar that
would meet the following requirements.
-Input file of external IP ranges I am responsible for
-Have the tool scan all ranges to determine responding
IPs
-Compare results to previous week and note exceptions
-Scheduling capability to have this take place weekly
>From a quick search, I found these two tools that I
might try out if I have
time. I have not heard of them before and have not
had a chance to read up
on their capabilities:
http://sourceforge.net/projects/gwmos/
http://sourceforge.net/projects/cancerbero/
I am also interested to hear thoughts on the best way
to do host discovery.
Many of our firewalls will block ICMP requests which
is fast and not
complete. Scanning for every TCP and UDP port can
take days. I'm looking
for a good middle ground that would be fairly complete
but not take an
excessive amount of time. I currently scan for about
15 common TCP ports
which takes about half of a day.
You can also consider using hping to check for the netbios port rather
than a basic icmp.
This could go through the firewall if your rules allow it.
You can then run an nmap to check which ports are open if the netbios
responds on hping.
I have the ability to run these on either a Windows XP
machine or a web
server (php, etc.).
hping works better on Unix/Linux.
Thanks in advance.
