A quick look at object_id in ruby..

Ruby VALUEs and object_ids @oreillynet has a detailed explanation about the assignment method.

pcaprub

Pcaprub was very fractured throughout the ruby community so I merged many of the projects together. This is the new hotness. :)

gem install pcaprub

VBS Script to map NAS network smb drives over specific SSID wifi homenets (non GPO script)

I recently posted this script on usenet because some many people now
have NAS storage devices accessible via there home wifi networks.

This script should help out the people with the question on how to mount a network attached storage device (like my coolmax NAS) to there windows profile during windows boot.

This vbs works by utilizing the wmi and cimv2 mappings to access the the MSNdis_80211_Configuration and the Win32_NetworkAdapter references.

You need to have the local WMI service enabled for this to work.

FYI:This has been tested under Windows XP.

DNS version attempts & tools

There has been some DNS junk flying around again.. so refresh.

Dont forget how easy it is to do a DNS version attempt.

dig @ns.example.com -c CH -t txt version.bind

Make sure your BIND/Named is obfuscated/disabled with custom message..

options
{
version "Generic DNS Server";
}

Not that it helps much with fpdns around.

anonymous@:~$ fpdns -D google.com
fingerprint (google.com, 216.239.34.10): ISC BIND 8.3.0-RC1 -- 8.4.4
fingerprint (google.com, 216.239.36.10): ISC BIND 8.3.0-RC1 -- 8.4.4

Perl: (Fingerprint.PM)


Make sure your read basic DNS information like

Cisco's: DNS Best Practices, Network Protections, and Attack Identification

And understand the principles laid out in Secure BIND configurations such as:
http://www.cymru.com/Documents/secure-bind-template.html

Look into DNS Debug tools such as DNSwalk, dlint, & DOC

And for reverse lookups use where there is no PTR record try A record caches like:
