NAME
ftpusers — security file for ftpd
DESCRIPTION
ftpd
rejects remote logins to local user accounts that are named in
/etc/ftpd/ftpusers.
Each restricted account name must appear alone on a line in the file.
The line cannot contain any white space.
User accounts that specify a restricted login shell in
/etc/passwd
should be listed in
/etc/ftpd/ftpusers
because
ftpd
accesses local accounts without using their login shells.
UUCP accounts should be listed in
/etc/ftpd/ftpusers.
If
/etc/ftpd/ftpusers
does not exist,
ftpd
skips the security check.
EXAMPLES
Given an
/etc/ftpd/ftpusers
file containing 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
would reject login attempts using the local accounts
uucp
or
