SSH connection slow in RHEL 7

-

 


Sometimes we faced issue with making ssh server connection very slow. It takes time while we access it through terminal or any third party tool. Below is one of the common solution for this issue.

Step1- Go to the SSH Server then edit /etc/ssh/sshd_config

Step2- Set UseDNS no and save file



Step3- Restart service after changing sshd_config

RHEL7(Higher)- systemctl restart sshd.service

Ubuntu- sudo service ssh restart  or you can use sudo /etc/init.d/ssh restart

How to save git token key to avoid again and again put manually

  To avoid entering your Git token key manually every time, you can use Git's credential helper to save and cache your credentials. The following steps outline how to set it up: 1.Open a terminal or command prompt. 2. Set up the Git credential helper by running the following command: git config --global credential.helper cache This command configures Git to use the cache credential helper, which will store your credentials in memory for a certain period of time. 3.Set the cache timeout (optional): git config --global credential.helper 'cache --timeout=3600' This command sets the cache timeout to 3600 seconds (1 hour). After this period of inactivity, Git will prompt you to enter your credentials again. 4.The next time you interact with a remote Git repository that requires authentication, enter your username and password (or token) as you normally would. Git will cache these credentials for the specified timeout period. From now on, you won't have to enter your Git toke...
