So it turns out that you can’t pass one vpn using ipsec through another vpn using ipsec.  Why, well i’ve spent some time trying to figure this out the last few days and have discovered that they are taking each others packets apart. VPN that use ipsec for a site to site connection encapsulate packets into udp packets.  These udp...

I love using Mac, as a so called IT professional it’s the most professional improvement to come UNIX in over a decade.  I especially like to use it for work,  The problem isall of the systems they use at my company rely on CAC authentication.  More specificaly it’s all been geared towards Windows & CAC.  Don’t get me wrong Common...

There are two schools of thought for how to clone drives under unix. The quick and dirty method is via the unix command dd. This is a bit for bit copy tool So it can even copy master boot records and partition tables. But it also copys empty space and kinda requires the drives be identical. Since it’s rare to...

I found one that checks the auth against ldap then creates a local mysql account. This also didn’t use a actual ldap data sourc e either, it just handeled it’s own ldap connection.

The name service cache daemon has some serious flaws. One that I notice pretty often in Linux arises when you are using LDAP. It seems that nscd will crash and burn when/if ldap is unavailable. Unfortunately when nscd bombs, it usually takes the entire system with it. Actually what will happen is nscd sockets will start getting broken pipe’s and...

LDAP has been around for over a decade, and yet it is still considered a newer technology.  Many modern vendors have added LDAP authentication.  This document is a brief generic howto for configuring linux to use LDAP.  This will be a fairly detailed recipe as most of my docs are. Linux Name Services Name Server Switch is the engine that...
