Enabling TELNET in Windows 7

It turns out that by default TELNET was not packaged with Windows 7. Apparently this was also true for Windows Vista.
Telnet is known to be insecure and so by default, Microsoft now DISABLES any likely security holes. Whenever you can, you should always use SSH.
That being said, you can enable Telnet this way:

  1. Start
  2. Control Panel
  3. Programs And Features
  4. Turn Windows features on or off
  5. Check Telnet Client
  6. Hit OK

After that you can start Telnet via the "CMD" - Command Prompt.

Microsoft SQL Server version checking

You can run the following SQL Query to determine the running Version of SQL Server 2005:
"SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')"

Release Sqlservr.exe
RTM 2005.90.1399
SQL Server 2005 Service Pack 1 2005.90.2047
SQL Server 2005 Service Pack 2 2005.90.3042
SQL Server 2005 Service Pack 3 2005.90.4035

If you get an error message that "Agent XPs" have not been enabled, you can execute these commands in the SQL Management Studio:

In order to ensure that its DS-integrated peer DNS servers are able to replicate with this server, an attempt was made to update them with the new records through dynamic update. An error was encountered during this update, the record data is the error code.

RFC 1918 - Private IPV4 Addresses

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:

  • 10.0.0.0 - 10.255.255.255 (10/8 prefix)
  • 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
  • 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

BGP Prefix List (for route filtering)

To filter routes 41.0.0.0 and 42.0.0.0 from bgp route declarations outgoing from RTR_SYDNEY :

RTR_SYDNEY(config)#ip prefix-list FILTER1 deny 41.0.0.0/8
RTR_SYDNEY(config)#ip prefix-list FILTER1 deny 42.0.0.0/8
RTR_SYDNEY(config)#ip prefix-list FILTER1 permit 0.0.0.0/0 le 32
RTR_SYDNEY(config)#router bgp 777
RTR_SYDNEY(config-router)#neighbor 172.12.123.1 prefix-list FILTER1 out

RTR_SYDNEY#clear ip bgp * soft

IPV6 Address Space - It's BIG

I thought this was an interesting analogy for the IPV6 Address Space:

Google Chrome OS ho-hum? I think not.

Article: "Google Chrome: The Official Start of the Cloud Era"
Author Lawrence Walsh says: "Google Chrome is being dismissed by competitors and analysts, but it may just be the official beginning of the cloud computing era by freeing users from big, heavy PCs and operating systems."

A fantastic medley of modules for the discerning drupal developer

A featured story on drupal.org: Case Study of OpenTheMagazine.com
In the story, we get a fantastic closeup view of the drupal modules used and the reasoning behind their use. For a young Drupal developer/user, it is a very useful article.

The "Heroes" of the site were considered to be Views 2, CCK, & for search, Apache SOLR.
The list below of other drupal modules used by the site is excerpted from the article on drupal.org:
