Here is a quick tip on how to receive an e-mail alert if your linux server or linux VPS restarts:

1. Log into your linux server or VPS using ssh.
2. Type in crontab -e into the commandline.
            Depending on the default text editor, it could be nano or vi. Here are the directions for vi:
3. Press insert button on your keyboard.
4. Then type in @reboot echo "Rebooted, now online" | mail -s "`hostname` REBOOTED" you@yourdomain.com
5. Then type in :wq to save and quit the vi text editor.

If your default text editor is nano, then the commands to type in are:

3. Find a new line or create one by pressing the Enter key.
4. Now type in on one line:

@reboot echo "Rebooted, now online" | mail -s "`hostname` REBOOTED" you@yourdomain.com

5. Then press CTRL and X on the keyboard to save.
6. Press Y to save the changes. Press Enter to exit.

If you want to send the e-mail to multiple people, edit the line to show this instead:

@reboot echo "Rebooted, now online" | mail -s "`hostname` REBOOTED" -c "user2@yourdomain.com" you@yourdomain.com

Now you will receive an e-mail alert when your server or VPS reboots. Very handy in troubleshooting issues with your VPS provider or your own server.

Fix problems with Cut/Copy/Paste not working when using Remote Desktop

Occasionally when using mixed OS environments and running Remote Desktop Client between the computers, you might have an issue where Cut/Copy/Paste stops working, or only listens to local clipboard content. This seems to happen mostly when connecting to remote Windows XP computers. Here's a quick way to fix the problem (not a permanent fix unfortunately).

1. Create a BAT/CMD file.
2. Open file in Notepad or whatever editor you want to use, and add the following content:
taskkill /im rdpclip.exe
start rdpclip.exe
3. Save the file and leave it on your Windows XP desktop.

Next time the issue happens, run that file to fix the issue. It will only fix it during that Remote Desktop session.
