PROGRAM:

NAME


twoftpd-xfer - TwoFTPD file transfer back-end.

SYNOPSIS


twoftpd-xfer

DESCRIPTION


twoftpd-xfer reads FTP request from the network and executes file transfers based on those
requests. Before doing anything, twoftpd-xfer changes directory to the authenticated
user's home directory, changes the root directory to that directory, and drops all root
priviledges.

ENVIRONMENT


AUTHENTICATED
If set (typically by twoftpd-auth after successfully completing authentication),
the startup banner will use code 230, indicating that authentication was
successful. Otherwise, the startup banner will use code 220, which is the normal
initial connection banner.

BANNER If set, the contents of this variable will be sent as extra responses when the
server starts.

CHROOT If set, change the root directory to the user's home directory through the OS
chroot syscall.

CONNECT_TIMEOUT
The maximum number of seconds to wait for a data channel connection to complete.
If not set, it defaults to the value of $TIMEOUT.

GID Numerical group ID number to change to at program startup.

GIDS Optional comma-seperated list of numerical group IDs to set up as the supplementary
group IDs.

GROUP Group name to use in long listings for files owned by $GID. If not set, defaults
to mygroup.

HOME Directory to switch to on program startup.

LOCKHOME
If set (and neither CHROOT nor SOFTCHROOT are set), all accesses to files and paths
outside of HOME will be forbidden.

LOGREQUESTS
If set, all requests from the client will be logged.

LOGRESPONSES
If set, all responses to the client (after login) will be logged.

MESSAGEFILE
If set, the contents this file will be automatically sent as extra responses to the
client whenever the server enters a directory (including at startup).

NODOTFILES
If set, all listings will exclude all files starting with a period, and it will not
be possible to do any file access (including storing or retrieving) to any file
starting with a period. This may be useful for anonymous FTP servers.

SESSION_TIMEOUT
The maximum number of seconds to allow a single session to last.

SOFTCHROOT
If set, and CHROOT is not set, the server emulates the effect of a chroot without
actually effecting a chroot. This eliminates the system-enforced barrier provided
by the chroot, but allows for things like symlinks outside of the home directory.

TCPLOCALIP
The IP to use when creating PASV connections. Normally, this is set by tcpserver.

TCPREMOTEIP
The source IP to use when creating PORT connections. Normally, this is set by
tcpserver.

TIMEOUT
The maximum number of seconds to wait for command input or connections.

UID Numerical user ID number to change to at program startup.

USER Owner name to use in long listings for files owned by $UID.

NOTES


You will need to set the umask to an appropriate value before running this program.

The twoftpd-anon program functions identically to this program, with the exception of
having no file modification capabilities. The twoftpd-drop program is a similarly
restricted program, that can only create new files (no overwriting, modifying, or listing
existing files).
