Hello Guys, hope you all doing great. After a major gap I am back to my blog to write some useful information which could help someone who is working on Linux servers :)

So, today i am going to discuss about a general error which comes on linux servers when we try to install any package or making changes in some directories.There might be other reason as well when this errors comes. So error which i am talking about is 
Error:


 /bin/sh: bad interpreter: Permission denied
Understanding the error:

Most of you might have come across this error.So question comes up what this error is saying:
and as per me its saying about some permission denied to the bash not able to access/write/execute the certain directory on linux server.

What directory is being denied:

The directory being denied is generally /tmp, because /bin/sh shell tries to execute some raw calculations inside the /tmp directory which is generally mounted and having permission set as no execute permission for /tmp partition.

How to get rid of it:

Just run below command to make the /tmp partition to execute the commands inside for the users.
 
Where we are remounting the /tmp partition with execute permissions, so that our error could get away and we can move forward with our work.

Once you will run above command, your error should be gone, but take a IMP note here, once you are done with your task whatever it may be, dont forget to remount the /tmp with default permissions.

and doing so is the good practice :) and to do that run the below command.

Solution and Step to fix CVE-2019-5736 Vulnerability - Docker

By Linux For Every One
Recently a new vulnerability has been discovered in the the internet market having target to Docker services. What is this Vulnerability: In short, Docker service uses another service called as runc which is container run time to spawn and run containers. which simply means if docker task is to create docker images then runc task would be running them and attaching a process to container. So as per the recent discovery by the maintainers of runc, the code of this service was having some bug which can be used by attackers to gain the root level of access of the host machine on which docker containers are running. How it can be Exploited: This vulnerability can be exploited in two ways (1) if the docker images are in use is vulnerable making the containers build from it vulnerable also (2) if somehow attacker got the access of containers and then trying to exploit using the bug present in runc and trying to get root privileges.

How to Generate CSR using Openssl in Linux

By Er.Susheel
Before Generating CSR ,let see what is Openssl. It is nothing but a core library ,which is used for general purpose in cryptography,it is an open source product which work towards the implementation of SSL and TLS protocols. Talking about openssl, some people called the certificates generated from openssl as "self signed certificate". lets go towards now,creating CSR and private key using openssl command, Just log in to any of your Linux box and run following command as  root user  replacing the required information as per your need . [root@SVR home]#   openssl req -new -newkey  rsa:2048 -nodes -sha256 -out domain_name.csr -keyout domain_name.key -subj "/C=US/ST=state/L=locality/O=organization/OU=organization unit Dept/CN=www.domain.com"  You will get output like : Then check whether ,all the information we have entered ,while creating CSR is proper ,by decoding the CSR from some online tool. First do the cat to the csr file [root@SVR home]#  cat

Multiple instances of redis

By Er.Susheel
In the last post I have covered how to install redis server on Centos/Rhel using rpm method and yum method and some troubleshooting skills. In this post i am going to cover how to install and configure redis to run with multiple ports.                                                                           But why we need more ports ? If you have read my earlier post , you already know that by default redis runs on single port 6379, which any one can use it for small website to cache the data. But for heavy website like magento we need to use additional ports along with 6379 to serve different cache from different ports. Like in Magento there is simple cache which is normally stored under /var/cache directory. Then there is Full Page Cache which is stored under /var/full_page_cache and session cache which is stored under /var/session_cache. Note : Discussion about cache/full page cache/session is not under the scope for this document.
