How to create CRONTAB to restart ubuntu

Use cron (should already be installed): Edit crontab: sudo crontab -e The first time you might have to choose your preferred editor (like nano) Insert a line like 0 6 * * * /sbin/shutdown -r +5 at the bottom. Explanation: m h dom mon dow command minute hour dayOfMonth Month dayOfWeek commandToRun so the line 0 6 * * * /sbin/shutdown -r +5 would reboot your system every day at 6:05am. (6:00am + 5 minutes) Ctrl+X, Y, Enter should get you out of crontab (if using nano) Note: you might have to run crontab -e as root, because shutdown needs root.

[ Windows ] Set the size of the "Buffer Memory"

 
By default Windows 7/Vista make use of only 512 Kb of your RAM as "Buffer Memory", to optimize exchanges between the Hard drive and the Main Memory.
If your system sports more that 1GB of RAM, then you can increase the space allocated.

For this you must make some modifications in the registry (better make up a backup before).

• Click on Start/Run/regedit.
• Expand the following key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager/Memory Management.
• Search for the following value: IoPageLockLimit
• In the case the value doesn't exist, create it:
  • Right click and choose New > DWORD Value (32bit).
  • Name the value IoPageLockLimit and double click it.
• Select Hexadecimal (base).
• Enter value F0000 and click OK.
• Close the Registry Editor and restart your PC to apply the change.

Server has a weak, ephemeral Diffie-Hellman public key

Hi,
I am writing this blog to help saving time for admins like me who are getting this error in their browsers "Server has a weak, ephemeral Diffie-Hellman public key"

The server.xml in tomcat is looks similar to this :

       clientAuth="false" sslProtocol="TLS"/> 

With Firefox, I get the untrusted communication error. and there are no errors in catalina.log.

Solution :
Just add this below keystorePass

ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA"

 and Save.

It should look like this :

ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA"

clientAuth="false" sslProtocol="TLS"/>

Thats all friends, restart the service and the page will open normal.

Thanks
Rohit Kumar

How to re-register Windows Store Apps in Windows 10 / 8

We have seen many issues in which users having trouble using Windows Store Apps in Windows 10 / 8 and Windows 8.1. Sometimes, the apps refuse to start and take you back to the Start Screen. In some other scenarios, you may receive This app can’t open error. In yet other cases, users are not able to update existing apps to solve the issues they’re experiencing with the current version. In all such cases, there is one thing you can try, and that is to re-register the apps.

If the system apps are unable to start due to issues with the user account, the problem can be solved by creating a new admin account, because Windows automatically sets apps to factory defaults for new accounts. Re-registering of apps is an offline operation and you don’t need to stay connected to the Internet for that. It can be done via executing a simple command in Windows PowerShell. If you’re facing issues with multiple issues with apps on your system, try to re-register the apps and get rid of the issues.
