Jenkins Slave - The specified working directory should be fully accessible to the remoting executable RWX

Question

I am getting below error while launching a slave node from jenkins master.

Exception in thread "main" java.io.IOException: The specified working directory should be fully accessible to the remoting executable (RWX):

[07/07/21 18:10:40] [SSH] Starting agent process: cd "/home/user" && /usr/java/jdk1.8.0_131/bin/java  -jar remoting.jar -workDir /home/user

Slave JVM has terminated. Exit code=1
[07/07/21 18:10:40] Launch failed - cleaning up connection
[07/07/21 18:10:40] [SSH] Connection closed.

I tried some solutions;

• User permissions and file permissions provided
• Java home is correctly updated
• Slave configuration is also fine

Please help me to know if I am missing anything important in my slave setting before launching.

Answer 1

Solution for this issues was very easy, the problem was I mistakenly created a user from root with root's permissions set on /home/user directory.

changed the users home directory permission to username:group and it worked fine.

sudo chmod -R user:groupid /home/user 

or

sudo chmod -R 777 user:groupid /directory-path

Please note this user has been used on slave machine configuration of Jenkins so the permissions should be sufficient to access workspace.
