Symptoms

  1. On attempt to add service node task failed with the following error message:

    Unable to authenticate at the host '10.249.28.197'. To resolve this issue, please follow the instructions at https://kb.parallels.com/116606.
    
  2. Instructions from the article mentioned in the error message did not help.

Cause

This issue caused by incorrect permissions for the /opt/psa_agent/internal/auth. Most probably permissions were set incorrectly in result of umask settings.

Resolution

  1. Check permissions on the /opt/psa_agent/internal/auth:

    # ls -la /opt/psa_agent/internal/auth
    -rw-r----- 1 root root   48 Jan 22 19:38 /opt/psa_agent/internal/auth
    
  2. Set correct permissions for the /opt/psa_agent/internal/auth:

    # chmod 644 /opt/psa_agent/internal/auth
    # ls -la /opt/psa_agent/internal/auth
    -rw-r--r-- 1 root root 48 Jan 22 19:43 /opt/psa_agent/internal/auth
    
  3. Specify default setting for umask in the /root/.bashrc or /etc/bashrc files.
