Speed up your browsing of Windows 2000 & XP machines

Speed up your browsing of Windows 2000 & XP machines

Here's a great tip to speed up your browsing of Windows XP machines. Its actually a fix to a bug installed as default in Windows 2000 that scans shared files for Scheduled Tasks. And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because Windows 2000 is using the extra time to search the remote computer for any Scheduled Tasks. Note that though the fix is originally intended for only those affected, Windows 2000 users will experience that the actual browsing speed of both the Internet & Windows Explorers improve significantly after applying it since it doesn't search for Scheduled Tasks anymore. Here's how :

Open up the Registry and go to :
HKEY-LOCAL-MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace
Under that branch, select the key :
{D6277990-4C6A-11CF-8D87-00AA0060F5BF}
and delete it.
This is key that instructs Windows to search for Scheduled Tasks. If you like you may want to export the exact branch so that you can restore the key if necessary.
This fix is so effective that it doesn't require a reboot and you can almost immediately determine yourself how much it speeds up your browsing processes.

unix tips, convert man pages to text files, linux tips, solaris tips, How to replace text in multiple files, execute commands at specified times

 Hi
Below some important general unix tips:

• How to run a command to a set of files (The while read command can handle names with spaces but you need to quote the variable after):

  [unix]$ for i in `ls *mp3`; do cp $i $i.bak; done

  [unix]$ ls *mp3 | while read i; do cp "$i" "$i with more spaces"; done

• How to rename part of a file:

• How to change all letters to lowercase:

  [unix]$ echo FilENamE | tr A-Z a-z

• A good way to change all filenames in a directory to lowercase:
  This handles a colored ls (hence the quotes around ls, but you can use any file list output, i.e. find) and names with spaces (hence the while read and not the for).

• How to convert man pages to text files:

  [unix]$ man man | col -b

• How to list all the open ports and programs:

  [linux]$ netstat -apne --inet
  [freebsd]$ sockstat

• How to list all the open files and programs:

  [linux]$ lsof
  [freebsd]$ fstat

• How to find information about an ip (i.e. 10.0.0.0):

  [unix]$ host 10.0.0.0
  [unix]$ dig -x 10.0.0.0

• How to find information about an ip owner (i.e. 10.0.0.0):

  [unix]$ whois -h whois.arin.net 10.0.0.0

• How to find out the mailserver for an ip:

  [unix]$ dig mx some.domain.name.net

• How to generate a filename with yesterdays date (i.e. for logfiles/backups):

  [linux]$ touch logfile-`date -dyesterday '+%Y-%m-%d'`
  [freebsd]$ touch logfile-`date -v-1d '+%Y-%m-%d'`
