Change your Skype settings and avoid DDoS attacks

Image
If you know someone's Skype username, you can get their IP address. The person can enable some options that stop non-contacts from getting their IP address with just their Skype username, but most people don't know how to do that. It also isn't foolproof. You can be invited to a conversation by someone else, then everyone in there can get your IP address. Your IP address is then used to DDOS you. DDOS stands for Distributed Denial of Service. You get so much data sent to your IP that it makes your internet connection largely unusable. Thus you lag a lot or disconnect from the game you're playing, which sucks if you're in the middle of a competitive match. You can protect yourself better by using something other than Skype, or by buying a proxy and setting up Skype to use said proxy. Proxy aside, here are some some Skype settings you can set to better protect yourself: Options -> Advanced -> Connection -> Uncheck "Use port 80 and 443...

How to check the processes and services run by svchost.exe

Image
On Windows, applications are built as exe files and code libraries are built as dll (dynamic-link library) files. The dll files contain reusable programs such as database engines, 3D renders, graphing capabilities etc. The application developers need not bother about writing these libraries all over again and can use these libraries by referencing the dll files in the application program. Exe files can run as a process, but that is not possible for dll files. Windows needs an exe process to load the dll file(s) and then let other processes call a function in the dll code. One more reason for hosting dlls separately is that some of the code has to run as a super user and running that code from the application as a constrained user is not possible. svchost.exe does the job of loading the dll files in a process with SYSTEM user. One or more dll files are grouped by their functions and are loaded into the svchost.exe process. So based on the number of groups these dll files can fo...

Get rid of animations and focus on task at hand

Image
When you are closing, opening or minimizing windows, animation effects are rendered (I guess to make it look more dramatic). I can live without those animation effects, and if you are like me, you can turn off unnecessary animations by following these steps: Open the Control Panel and click on  Ease of Access Center . Scroll down and click on  Make it easier to focus on tasks. Scroll down again and check the option Turn off all unnecessary animations Apply the changes

SAP Process Integration Starter Guide for Basis Administrators

Image
This is a starter guide for Basis Administrators to understand the architecture and various nuances of SAP PI Administration. This guide will be updated time to time, so I recommend you to bookmark and keep revisiting this page as you see fit. Enterprises run different software solutions to support their business processes. Not all of them are built and supported by SAP. These solutions are integrated one-to-one using various middleware solutions or customized programs or scripts. When there is a change in one system or business process, multiple point-to-point interfaces are affected and are often expensive to change. Although these point-to-point interfaces are using different technologies, there are recurring themes. Although there are recurring themes, code is not reusable because they were implemented using different technologies. In 2003, SAP introduced NetWeaver, which helped them focus on providing a platform for integrating various aspects of business , in...

Microsoft to Support Secure Shell (SSH)

Image
Good news from Microsoft PowerShell Team! Microsoft will be supporting SSH on Windows. The solution is in the planning stages and the date of availability is not known yet. If I am reading the announcement from the PowerShell team right,  you can SSH into a Windows box from *nix and vice-versa. Hopefully key based authentication using PuTTY will be possible as well. In case you can't wait, there are third party solutions available right now, such as  PowerShell Server , that support SSH and SFTP in to Windows. Windows 10  has already brought in "drag to select text", ctrl-c and ctrl-v to the command prompt; and now this announcement! I hope this also means SFTP and SSHFS support. Then we could finally say goodbye to SMB! This is a really helpful support to system admins from Microsoft! Share it on Facebook Twitter Google+ LinkedIn

Important Sap Gui Key Shortcuts That Will Increase Your Productivity

The area in which you enter an SAP transaction code is called Command-field or "OK Code". The shortcut to select this command field is CTRL+/ Here are some entry options for OK codes: /n - The /n option terminates the current transaction /n<TXNCODE> - The /n option terminates the current transaction and TXNCODE followed by /n calls transaction TXNCODE /nend - This option terminates all the sessions from the current PC and logs the user off. /nex - This option terminates all the sessions from the current PC and logs the user off immediately without issuing warnings /o - The option /o lists existing sessions and allows deletion or opening of a new session. /o<TXNCODE> - The option /o followed by a transaction code TXNCODE opens a new session and starts transaction TXNCODE in the new session. If the maximum number of sessions per user are breached, an error is displayed. /i - The option /i terminates the current session /i1 - The option /i1 terminate...

A new design

Image
I have spent this weekend getting to know how to build my own template from the scratch and try to provide a better user experience on this blog. I think I have met my goal to an extent. The credit goes to blackout on reddit and hammering of its alternatives' servers. I am also working on a sitemap to help my readers find other relevant stuff on this blog. I have to sift through all my posts yet to complete this sitemap. This is the first step. There will be a second sitemap to help navigate through non-SAP stuff on my blog. If I can figure out a better way to provide relevant posts on the blog post itself, I will add that feature. I used to use nRelate, which is now discontinued. If you know of a service other than linkwithin, please leave a comment! If you think your colleagues/followers/friends (usually the same) would like this blog, please mention us on Facebook , Twitter , LinkedIn  or Google Plus ! You don't want to do that? :-( Take this quiz to test your B...
