Hello,

a scan of localhost takes 180 Seconds. 1000 Computers would take 50 hours.
Is there any way to scan some host (10 or 20) simultaneuosly?

Actually, I scan from one host my whole network. Is it better to run the audit by loginscript? My user have not admin-previliges.

Kind regards

matze

If you look in the audit.config file, you'll see a line that looks like this:

number_of_audits = 20

That number controls how many audits are run simultaneously. So, by default, it will audit 20 machines at a time. If you're on a domain, it will pull down the list of computers and start scanning them, so it won't take 50 hours!

Is it possible to scan a network based on a tcp-scan instead of ldap?

Currently, no. It wouldn't be incredibly hard to do, but what is your reason for needing a tcp-scan instead? I want to know how your network is setup to see what the best solution is.

Hallo mikeyrb,

thanks for your help.

We run a NT4-Style Samba controlled Domain with OpenLDAP as backend on 10 Locations (connected via 2mbit vpn).

Actually, we run our inventory software based on a portscan at each locations-subnet 2 times a week.

But after studying the code and config-files, I think that we can scan our network with the hosts from ldap. Could you give me more informations about configuring scanning by ldap?

You will need to modify these lines in audit.config:

audit_local_domain = "y"

local_domain = "LDAP://"

Make sure audit_local_domain is "y" and then add your domain to local_domain, so if your domain was MYDOMAIN.COM, then that line would read:

local_domain = "LDAP://MYDOMAIN.COM"

Hello,

this is my config.

audit_local_domain = "y"
local_domain = "ldap://servername/ou=computers,o=company,c=com"

But running "cscript audit.vbs" only audits the local pc. "cscript audit.vbs computername" works fine.

Ah yeah, I forgot to mention that! Change strComputer to equal ""

C:\Programme\OpenAudit\audit.vbs(151, 3) Provider: Tabelle ist nicht vorhanden.

I'm not using AD. It's pure LDAP.

Yeah, the script was written for AD. We'll have to look into LDAP, but if you find out anything, let us know.

My first solution is to generate the pc_list_file.txt by ldapsearch from OpenLDAP and some Gnu-Tools:

C:\Programme\OpenLDAP\ldapsearch.exe -H "LDAP://server" -b "ou=computers,o=company,c=com" cn | grep cn: | cut -d ":" -f 2 | sed s/\$/,,/ | tr -d "\ " > C:\Programme\OpenAudit\pc_list_file.txt

Is it possible to implement puren LDAP in the release?

This Code works fine:

Set ou = GetObject("LDAP://server.de/ou=computers,o=company,c=com")
For Each obj In ou

strComputer = Replace(obj.cn,"$","")
WScript.Echo strComputer

Next

All Machine-Accounts In Samba 3 have the "$"-Suffix, this must be replaced.

I assume you mean universal LDAP approach, on that will work with both AD and SAMBA (and in theory Novell or any other LDAP).

Yep, is this possible?

I would think so, but I will look in to it. Why not add it to the feature requests.
