After a while you notice that timestamps in your logfiles are shifted with few hours. So what could be wrong?
Actually is really simple – most probably your timezone is not correct. To check run “date” from command line, this will show what is the time for your server.
Then you find that the timezone is not correct?!

How do you set the correct one?

Unfortunately, this is not an easy thing to figure out. Official documentation states that you can use system-config-date, but it has a bunch of dependencies (when I ran yum install system-config-date on one of my servers it asked to install 84 packages).

So is there an alternative way to do it?

All timezone files are located in /usr/share/zoneinfo. To select the appropriate named timezone for your location. For my location, Montreal, Canada, I actually have to select: America/Montreal. For you it could be different so make note of the appropriate folder and file for your timezone.

The active timezone used on your system is in the /etc/localtime file.

The default will vary depending on your server host and it depends on the value that was provided during installation.
We simply need to replace this file with the file we selected in the previous step.
Even I say replace, actually is recommended to create a link to the pertinent file rather than actually replacing the file.

Here are the steps to follow:

First, backup the existing localtime file (it is always good practice to make backups of original config files).

mv /etc/localtime /etc/localtime.bak

Next, create the link:

ln -s /usr/share/zoneinfo/ /etc/localtime

Test your change.
Run “date” from the command line, and ensure that the appropriate time, date, and timezone are reported.

“Your temporary license about to expire in… days”

This is usually dye to misconfiguration on the server side, but here is the trick to get additional 90 days temporary license:

WARNING: This requires editing of Windows registry. Use it on your own risk.

1. Launch regedit – Start -> Run… -> regedit
2. Go to HKLM\Software\Microsoft\MSLicensing\
3. Delete hardwareID entry.
4. Enjoy another 90 days, but not forget to plan for fixing the issue

Unfortunately the tool was not installed.
The proper way of installing it is:

apt-get update && apt-get install dnsutils

In case you did update recently you can skip the first command.

For more info:
man screen

Recently I experienced following error:
$ screen -r
Cannot open your terminal '/dev/pts/0' - please check.

After searching for solution I found several instructing to change permissions etc.

But different solution, almost “hack” is the one I like.
Before starting screen type:
script /dev/null
And after that you can type:
screen -r
Only drawback is that you need to type one additional exit for script to terminate.

Credits for this to Harry Jackson. Unfortunately the resource was not available so i did to put a link to the site.

As addition to Fix Hibernate in Windows XP here is additional shortcut I discovered.

To activate hibernate option I had to press <shift> every time I go to shutdown menu, but once I did not and it worked…

So here is the full shortcut:

<WinKey> -> <U> -> <H>

What that means?

- Start menu
- Shutdown
- Hibernate

• Stand by
• Turn off
• Restart

But there is another option called Hibernate. As name suggests when you choose that option your computer goes in deep sleep. This is different from Stand by mode and Shutdown and actually is in between.
In that mode Windows XP does the same as Stand by, but in addition writes memory dump on the hard drive and turns off the PC.
After you power up the PC the memory dump is loaded in the memory and computer resumes operation as after stand by.
It takes a bit more time for that operation, but is much less hat initial power up.

How to enable Hibernate?

1. Make sure that you are logged in with administrator account. You can do that by going in Start -> Control Panel -> User account
2. Go to Power Options and choose Hibernate tab
3. Check Enable hibernation
4. Now you are able to hibernate your computer

Troubleshooting:

• I do not have hibernate icon

If on turn off menu you do not have hibernate icon it means that you have newer computer BIOS that supports Stand by by lower power option.
If you want to hibernate you need to press Shift button until hibernate icon appears.

Here is how to disable them:
Go to Tools-> Preferences -> All -> Interfaces -> Main Interfaces -> Qt
and uncheck Notify on track change.

Instead of that the cursor was moving in the text.

Finally I realized that this is used to select text. And surprisingly enough I was in Select mode.

Right click and change to Hand tool and I now have the desired behavior.

Hope this will help someone.

I’m used to the folders created after update in \WINDOWS and after I’m sure that there is no problems with the update they could be safely erase, but this was something new.

After browsing the contens my initial thougths were confirmed those were temporary folders from windows update.

So I erased them…

I typed:

 find . *.gz

And received:

-bash: /usr/bin/find: Argument list too long

After searching on internet I saw a lot of similar problems, but then I remembered one of my old posts

bash: /bin/rm: Argument list too long – How to fix it

After reviewing it for on more time I found my mistake

Correct syntax is:

find . -name "*.gz"
