Even brief periods of downtime for SAP applications can have devastating consequences for business operations, including production and supply chain interruption, delivery delays, lost sales, data loss, payroll delays, customer service degradation, contractual liabilities and regulatory fines. Unfortunately, SAP offers little or no native support for the server clustering, data replication and failover recovery functions needed for assuring high availability and data protection. It is equally unfortunate that most IT organizations also lack the staffing needed to even consider using open source high availability software in a Linux environment. Fortunately, the growing popularity of SAP and Linux have given rise to a variety of viable alternatives for keeping SAP applications highly available and operating properly through the usual hardware and software failures, administrator errors, routine maintenance, and even site-wide disasters. The challenge is finding which one … [Read more...] about 5 Best practices for protecting SAP in Linux environments

How to access files on network devices using SMBv1 on Windows 10
Server Message Block (SMB) is a networking file share protocol included in Windows 10 that provides the ability to read and write files and perform other service requests to network devices. Usually, you'll be using SMB to connect to devices that don't run Windows, such as a router with file sharing capabilities, Network-Attached Storage (NAS), or other computers running Linux. Although there have been three major releases of the protocol, there is a chance that you may still have devices running the original version, such as SMB version 1 (v1) which is old and insecure, and Windows 10 no longer installs it by default starting with the Fall Creators Update and April 2018 Update. As a result, you'll get error messages like "You can't connect to the file share because it's not secure;" "The specified network name is no longer available;" and "Unspecified error 0x80004005" when trying to access your files. However, if you have a networking device that you can no longer access because of … [Read more...] about How to access files on network devices using SMBv1 on Windows 10

How to configure wireless wake-on-lan for Linux WiFi card
I have Network Attached Storage (NAS) server that backups all my devices. However, I am having a hard time with my Linux powered laptop. I cannot backup my laptop/computer when it is in suspended or sleep mode. How do I configure my wifi on a laptop to accept a wireless wol when using Intel-based wifi card? Wake-on-LAN (WOL) is an Ethernet networking standard that allows a server to be turned on by a network message. You need to send ‘magic packets’ to wake-on-lan enabled ethernet adapters and motherboards, in order to switch on the called systems. Wake on Wireless (WoWLAN or WoW) is a feature to allow the Linux system to go into a low-power state while the wireless NIC remains active and stay connected to an AP. This quick tutorial shows how to enable WoWLAN or WoW (wireless wake-on-lan) mode with a wifi card installed in a Linux based laptop or desktop computer.Please note that not all WiFi cards or Linux drivers support the WoWLAN feature.SyntaxYou need to use the iw … [Read more...] about How to configure wireless wake-on-lan for Linux WiFi card
