User limits

To enforce process limitations for the nfsuser user, you need to configure the limits in the /etc/security/limits.conf file. Follow these steps:

Step 1: Edit the Limits Configuration File

Open the file using a text editor:

sudo nano /etc/security/limits.conf

Step 2: Add Limits for nfsuser

Append the following lines at the end of the file:

nfsuser soft nproc 1026
nfsuser hard nproc 2026

Step 3: Save and Exit

Press CTRL + X, then Y, and hit ENTER to save the changes.

Step 4: Apply the Changes

Ensure the PAM module is enforcing these limits:

sudo nano /etc/pam.d/common-session

Confirm or add this line:

session required pam_limits.so

Save and exit.

Step 5: Verify the Configuration

To check the current limits for nfsuser, run:

ulimit -u -S
ulimit -u -H

You may also switch to the nfsuser account and test:

su - nfsuser
ulimit -u

This should reflect the soft and hard process limits.
