Display the motd file
' pam_motd.so 'u pam_motd.so [motd= /path/filename ]
pam_motd is a PAM module that can be used to display arbitrary motd (message of the day) files after a successful login . By default the /etc/motd file is shown . The message size is limited to 64KB .
motd= /path/filename The /path/filename file is displayed as message of the day .
motd_dir= /path/dirname.d The /path/dirname .d directory is scanned and each file contained inside of it is displayed .
When no options are given, the default is to display both /etc/motd and the contents of /etc/motd .d . Specifying either option (or both) will disable this default behavior .
Only the session module type is provided .
PAM_IGNORE This is the only return value of this module .
The suggested usage for /etc/pam .d/login is:.RS 4
