Rename a Windows domain connected workstation remotely

From the server/domain controller, run NetDom which will rename the workstation to what you want.
You need to reboot the workstation after running this command.

netdom renamecomputer old_name  /newname:new_name  /userd:domain_admin_login /passwordd:domain_admin_pwd

Sources: http://support.microsoft.com/kb/298593/en-US and http://technet.microsoft.com/en-us/library/cc788029.aspx

Another way to rename a computer is to use Powershell from a server or domain controller.

Rename-computer -computername “targetcomputer” -newname “newcomputername” -domaincredential domain\domain_admin -force -restart

How to perform a clean Windows 7 Upgrade.

1. Purchase Windows 7 Upgrade in the retail package. Your existing computer must have Windows XP or Vista on it.
2. Backup your data to an external harddrive, to a flashdrive, to a dvd, to a NAS, to the cloud, etc.
3. Put Windows 7 Upgrade disc in the computer. Use the 64-bit disc if your computer hardware supports 64-bit.
4. Perform clean install where you format the harddrive. DO NOT CLICK UPGRADE.
5. Follow through the install. When it asks for a license key, DO NOT ENTER THE LICENSE KEY. Click skip.
6. Finish with the install and you should be at the Windows 7 desktop.
7. Go to Computer then your optical drive, D: or whatever it is.

Compiling echoping 6.0.2 on CentOS/RHEL 5

Here is the commandline options I used to compile echoping 6.0.2 from source:

./configure --with-ssl=/usr/lib/openssl --without-libidn

Asterisk installation notes

Here are some generic installation notes for building and installing Asterisk in gnu/Linux. Should work for any distribution. I've tested them with CentOS 5.X.

Install missing development packages, then perform the following inside asterisk source directory:

contrib/scripts/install_prereq install
./configure

use ./configure --prefix=/usr/local/asterisk-1.x.xx.x to install to your own location

make menuselect

de-select unnecessary addons and features.

make

run contrib/scripts/get_mp3_source.sh to add mp3 support (install subversion first)

make config
make install-logrotate
make install

If running asterisk on a VPS, you may need to edit the safe_asterisk file and comment out the line where it says TTY=9 in order to get asterisk to run via initscripts.

To add asterisk messages to the daily e-mail report via logwatch:

Installing ConfigServer Firewall (CSF)

http://configserver.com/cp/csf.html

If you get the following error during installation:

Checking Perl modules...
Can't locate LWP/UserAgent.pm in @INC (@INC contains: /etc/csf /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 .) at (eval 19) line 2.

Then you need to install perl-libwww-perl package (as well as its prerequisites).

yum install perl-Compress-Zlib perl-HTML-Tagset perl-URI perl-HTML-Parser perl-libwww-perl
