You downloaded a CD image in a bin format. However, nothing will read it. Most software for mounting or burning the bin file requires a cue file and this describes how to create one.
This tech-recipe will explain how to setup Windows 7 to automatically login a user account. This is handy for computers that you use as HTPC machines or even for a ‘guest’ computer that you want to login automatically to a restricted account.
If you are using a low speed internet connection, loading a website which has many images may take a lot of time. This tutorial will show you how to hide those images when you visit the website on Google Chrome. This will not only help the browser speed up the loading time, but also prevent embarrassing moments from happening when the site contains NSFW images.
The Internet Options is the center place for tweaking most of all important settings in Internet Explorer. Because this option can be easily accessed by anyone, problems may arise when an user erases or tweaks the settings of other users. Luckily, you can lock the option by using this registry tweak.
It is sometimes necessary to refer to files in the host filesystem explicitly. By retrieving this information dynamically instead of hard coding it, moving the code from one server or hosting company to another is much simpler.
A cool feature in versions of BIND since 8.2 and 9.1 is the $GENERATE directive which can create hundreds or thousands of resource records with a single line in zone file. A common use for $GENERATE is assigning PTR records for a DHCP address range.
A single host may have multiple personalities: web server (www), mail server (mail, mx), dns server (ns), ftp server (ftp). Rather than assign each of these names an address (A) record pointing to the same IP address, all of which would need to be changed if the IP address changed, one name can be associated with an address record and the remaining names can be aliases for that name. The CNAME record simplifies DNS management, and who doesn’t want that?
BIND resource records allow an explict TTL value that will override the zone file’s TTL for that specific resource record. One use for this is to prevent non-authoritative servers from caching these records, perhaps in prelude to changing a server’s IP address.
The PTR (pointer) record maps an IP address to a hostname and fully qualified domain name. Many applications use reverse lookups to identify the domain from which a TCP/IP connection is formed. Best practice for DNS is to create a PTR record for every A record.
Adding static host name to IP address mappings in a router (like a UNIX /etc/hosts file) can make life easier. These can override DNS entries for the host when needed, and can make easy references to other systems or devices that are not appropriate for DNS entries.
