Details

Check Text (C-215342r991589_chk)

Check global initialization files for the presence of "mesg n" command by running: # grep "mesg" /etc/profile /etc/environment /etc/security/environ /etc/security/.profile /etc/csh.login /etc/csh.cshrc /etc/profile:mesg n /etc/environment:mesg n If any global initialization file does not contain "mesg n", or it contains the "mesg y" command, this is a finding.

Fix Text (F-16538r294478_fix)

Edit the global initialization files that do not contain "mesg n" command and add the following line to the initialization files: mesg n
