Each system administrator during his work accumulates small, but useful actions that facilitate the work in one or another area of his responsibility. Such actions or habits that he is used to and which he performs on automatism may not be familiar to his colleagues. Therefore, in this list, I want to make a selection of some of my habits and those collected on the Internet that may be useful to you.
- Use Delete instead of Shift + Delete to delete
- To save changes, always use the sequential click of the Apply buttons - OK
- Data replication does not cancel backup
- Always check the user's problem before proceeding to fix it.
- Double check that you are running the rm -rf command in the correct directory
- On servers, do not disable the request for the reason for shutdown / reboot. It can save you from accidental clicks.
- Do not use spaces in the naming files and folders. Always-use-english
- Write for users the batch file “Nothing works
for me. Bat ” in the batch file executing the commands systeminfo, ipconfig, shutdown / r / t 5
Sometimes rebooting magically helps - Do not perform updates or critical changes on Friday afternoon.
- The same applies to server reboots.
- Use the slowest speed to burn discs.
- Use combinations like CTRL + S, CTRL + C twice. To be sure
- Read the “release notes” before installing updates.
- Autocomplete also works in standard Windows paths. Use tab
- On the server, use the least privilege model. Configure local machine access for daily tasks ( RSAT ). Do not connect to the server as an administrator, only to create a new user
- If you have to connect via RDP / console to many servers, set different colors on the desktops / in the console to make it easier to navigate
- If you have to connect via RDP to many servers, display the “My Computer” shortcut on the desktop and rename it by machine name to make it easier to navigate
- Try to take screenshots of critical settings
- Before rebooting / shutting down, check the machine name. molly-guard
- If the hard drive is not detected, put it in the refrigerator for 12 hours ( Freeze your hard drive to recover data: Myth or reality? )
- The USB connector is the same size as the Eternet connector. Do not blindly connect
- Provide simple instructions for users to solve problems on their own. (For example, a block diagram for troubleshooting printing )
- After turning off the computer, count to 10 before turning it on again
- To increase computer performance, when you are waiting for a command to execute, rotate the mouse cursor clockwise, not counterclockwise
- Turn on the display of all the icons in the notification area
- Enable display extensions for known file types
- Display brief information about the computer on the desktop: machine name, username, ip ( bginfo )
- Take the habit of manually saving a document every 5-10 minutes
- Lock the screen before leaving the workplace, even if you leave for a short time
- Everything works? Do not touch!
- But, in continuation of the previous one, always apply all security updates
- If possible, transfer your old server to the virtual machine
- Periodically check the power of each device so that in the event of a power outage it was not necessary to restore its functionality in emergency mode
- Back up important information systematically
- The “Network Connections” control panel applet can be called via Win + R “ncpa.cpl”
- If the action can be automated, find a way to do it.
- According to RFC 2606, domains and subdomains are allowed as domain names for examples in the documentation: .example, example.com, example.net and example.org
- According to RFC 5735, ip ranges can be used as “white” IP addresses for examples in the documentation: 192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24
