Sendmail - Masquerading multiple domains

I have a little VPS that is used as platform for POP'ing and SMTP relaying for internal projects and testing.  Originally it was all setup under a single domain and I had turned on masquerading.  However I needed to add another domain for a different project.

Perl Script - Active Directory Password Expiration

There are alot of reasons to use Active Directory (AD) for your central authentication needs.  On a corporate AD network though, there may be some non-windows users that will not get the friendly password expiration reminders when they login to their systems.  Subsequently these users will get locked out when their password exipres.

CNAME / A with MX Records

Stumbled into an issue again today that has come up a few times for me, so I figured I will right out the reason for this as a friendly reminder.

The Scenario:

Fix - GotoMeeting Could not Connect

Had a very odd issue with GotoMeeting client on a Laptop PC.  The client refused to connect so the user could attend an online meeting.  It was acting like it had no network connection.

RealTek HD Audio and Windows7

I finally got around to rebuilding my primary desktop PC.  In addition to adding the second harddrive and creating a RAID1 configuration, I took the leap to Windows7.  Now my main desktop and my new Aspire Aspire Nettop media PC (review to come) run Windows7 on my home LAN.

Tip - DSADD and DSMOD Commands

Problem

Adding a large group of new Active Directory (AD) users and add them to a group.

Solution

Using DSADD and DSMOD command line options in a batch script.

Knowing the command syntax and having a Excel Spreadsheet of the User information, I created a bulk list of commands I executed by "batch" script.

Calendar Attachements in GoogleApps... NOT

error - expat.h: No such file or directory

While trying to get a perl utility working, I had to install a bunch of prerequisite perl modules on my CentOS 5 VPS.  One requirement was XML::Parser.  However when I tried to install it like so:

[root@localhost]perl -MCPAN -e shell
cpan> install XML::Parser

I received errors with the below being the most relevent bit...
