NcFTPd: Configuration: general.cf: a-ls-names

a-ls-names

The built-in /bin/ls can be configured whether to display user and group
names for the long-listing format. The default setting is to not print those for anonymous users. Not only is it faster, since it doesn't need to waste time looking them up, it is more secure for you since you don't want to give the world a list of valid usernames for your system.

When ls-names are off, the file's owner displayed from /bin/ls becomes ftpuser, and the file's group, ftpusers. You may also see this occur when the user ID or group ID does not correspond to a name in the /etc/passwd or /etc/group file.

You may find that after adding a user to the system that the ls-name is not displayed. This is because the names are only loaded at periodic times to avoid repeated processing of the passwd and group files. Eventually the change is noticed and the name will be re-loaded.

The a-ls-names controls the setting for anonymous users, while u-ls-names controls the setting for the non-anonymous users.

Examples:

a-ls-names=no

a-ls-names=yes

Recommendation:

a-ls-names=no
