  DNS

  Domain Name No Comments

  Domain name system Or server Or service.

  An Internet service that translates domain names into IP address. Because domain names are alphabetical. they are easier to remember. The internet however, really based on IP-addresses . Everytime you use a domain name, therefore, a DNS service must translate the name into corresponding IP-address.

  For example: The domain name www.example.com translate to 192.168.0.10

  The DNS system infact, it’s own network. If one DNS server doesn’t know how to translate a particular domain name, it asks another one and so on, until the correct Ip-address is returned.

  Convert ^M to newline character in text files

  HTML Hosting Tutorials No Comments

  If ^M character showing up in files while opening that file in vi editors use the following step to Convert ^M to new line character

  In vi use the following:

  :%s/^M/\n/g

  or with perl on the command line:

  $ perl -pi.bak -e ’s/^M/\n/g’

  NOTE: Be sure to create the ^M by typing ctrl+V followed by ctrl+M.

  ^M is ASCII 13 (Ctrl+M), which is the carriage return.

  Different operating systems use different symbols to set the end of a line/new line.
  Unix uses newline (\n)
  Mac uses carriage return (\r)
  And Windows/DOS use both (\n\r)

  To prevent the ^M from showing up in files, be sure to use ASCII (text) mode when transfering text files.
