Check for FTP login restrictions.
Syntax:
facility control_flag pam_ftpusers.so [debug] [disallow] [nowarn]
Options:
- debug
- Write a LOG_DEBUG message to the system log.
- disallow
- Success only if the user is not in the file (that is, the user not on the list).
- nowarn
- Turn off warnings so that the user does not ever see them. Don't use this option if anyone
needs to know why their authentication was denied.
Description:
Use the pam_ftpusers module to determine if the user is listed in
/etc/ftpusers. (The ftpusers file is a
list of users who are not allowed to run an FTP login.)
Note: The PAM module syntax does not stand alone and is contained within the context of the PAM
configuration command. See the
Security
Developer's Guide for more information about system authentication,
configuring PAM, facilities, control flags, examples, and how QNX Neutrino uses the OpenPAM framework.
Service category:
This module belongs to the account PAM service category.
Exit status:

Note: When disallow is specified, semantics are reversed, and it
fails if the user is listed.

Note: When disallow is specified, semantics are reversed, and it succeeds if the
user is not listed.
