Before doing anything, <B>twoftpd-xfer</B> changes directory to the authenticated user's home directory, changes the root directory to that directory, and drops all root priviledges. <A NAME="lbAE"> </A> <H2>ENVIRONMENT</H2> <DL COMPACT> <DT><B>AUTHENTICATED</B> <DD> If set (typically by <B>twoftpd-auth</B> after successfully completing authentication), the startup banner will use code <I>230</I>, indicating that authentication was successful. Otherwise, the startup banner will use code <I>220</I>, which is the normal initial connection banner. <DT><B>BANNER</B> <DD> If set, the contents of this variable will be sent as extra responses when the server starts. <DT><B>CHROOT</B> <DD> If set, change the root directory to the user's home directory through the OS chroot syscall. <DT><B>CONNECT_TIMEOUT</B> <DD> The maximum number of seconds to wait for a data channel connection to complete. If not set, it defaults to the value of <B>$TIMEOUT</B>. <DT><B>GID</B> <DD> Numerical group ID number to change to at program startup. <DT><B>GIDS</B> <DD> Optional comma-seperated list of numerical group IDs to set up as the supplementary group IDs. <DT><B>GROUP</B> <DD> Group name to use in long listings for files owned by <B>$GID</B>. If not set, defaults to <I>mygroup</I>. <DT><B>HOME</B> <DD> Directory to switch to on program startup. <DT><B>LOCKHOME</B> <DD> If set (and neither <B>CHROOT</B> nor <B>SOFTCHROOT</B> are set), all accesses to files and paths outside of <B>HOME</B> will be forbidden. <DT><B>LOGREQUESTS</B> <DD> If set, all requests from the client will be logged. <DT><B>LOGRESPONSES</B> <DD> If set, all responses to the client (after login) will be logged. <DT><B>MESSAGEFILE</B> <DD> 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). <DT><B>NODOTFILES</B> <DD> 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. <DT><B>SESSION_TIMEOUT</B> <DD> The maximum number of seconds to allow a single session to last. <DT><B>SOFTCHROOT</B> <DD> If set, and <B>CHROOT</B> 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. <DT><B>TCPLOCALIP</B> <DD> The IP to use when creating PASV connections. Normally, this is set by <B>tcpserver</B>. <DT><B>TCPREMOTEIP</B> <DD> The source IP to use when creating PORT connections. Normally, this is set by <B>tcpserver</B>. <DT><B>TIMEOUT</B> <DD> The maximum number of seconds to wait for command input or connections. <DT><B>UID</B> <DD> Numerical user ID number to change to at program startup. <DT><B>USER</B> <DD> Owner name to use in long listings for files owned by <B>$UID</B>. </DL> <A NAME="lbAF"> </A> <H2>NOTES</H2> You will need to set the umask to an appropriate value before running this program. The <B>twoftpd-anon</B> program functions identically to this program, with the exception of having no file modification capabilities. The <B>twoftpd-drop</B> program is a similarly restricted program, that can only create new files (no overwriting, modifying, or listing existing files). <P> <HR> <A NAME="index"> </A><H2>Index</H2> <DL> <DT><A HREF="#lbAB">NAME</A><DD> <DT><A HREF="#lbAC">SYNOPSIS</A><DD> <DT><A HREF="#lbAD">DESCRIPTION</A><DD> <DT><A HREF="#lbAE">ENVIRONMENT</A><DD> <DT><A HREF="#lbAF">NOTES</A><DD> </DL> <HR> This document was created by <A HREF="http://localhost/cgi-bin/man/man2html">man2html</A>, using the manual pages.<BR> Time: 22:19:53 GMT, April 04, 2011 </BODY> </HTML>
