NAME

ftpusers − security file for ftpd(1M)

DESCRIPTION

Ftpd rejects remote logins to local user accounts which are named in /etc/ftpusers.  Each restricted account name must appear alone on a line in the file.  The line cannot contain any white space.  User accounts which specify a restricted login shell in /etc/passwd should be listed in /etc/ftpusers because ftpd accesses local accounts without using their login shells.  Uucp accounts should be listed in /etc/ftpusers.  If /etc/ftpusers does not exist, ftpd skips the security check. 

EXAMPLES

If /etc/ftpusers contains the following:

Only lines that exactly match user account names are
significant.  Blank lines are harmless because they
do not match any account names.  However you must be
careful.
 uucp
guest

ftpd will not login to the local accounts “careful.”, “uucp”, or “guest”. 

DEPENDENCIES

Implemented on the Series 300 and 800 only.
