+tnfsd (trivial network filesystem server)
+
+TNFS is a simplified Internet file transfer protocol, designed for
+limited resource usage and ease of implementation on small systems,
+such as 8-bit computers. It's simpler than NFS, SMB, or FTP. It's
+similar to TFTP, but has features TFTP lacks.
+
+Since tnfsd has no access control other than file permissions, and
+since we generally don't want clients to have write access, this
+package uses a dedicated user/group for the daemon, and another group
+to control local write access to the shared directory.
+
+Before running this SlackBuild, you must create the tnfsd user and
+the tnfsd and tnfs-files groups. Use these commands:
+
+  groupadd -g 375 tnfsd
+  groupadd -g 376 tnfs-files
+  useradd -u 375 -d /var/tnfs -c "TNFS Daemon User" \
+          -M -g tnfsd tnfsd -s /bin/false
+
+After the package is installed, add any users you want to the tnfs-files
+group. These users will be able to create files in the /var/tnfs
+directory. Example:
+
+  usermod -a -G tnfs-files joeblow
+
+After the above command, the user joeblow will have to log out and
+back in, to join the new group. Once this is done, the user can
+copy files to /var/tnfs (or ~tnfs) and they will be visible to TNFS
+clients.
+
+TNFS uses port 16384, UDP (for most 8-bit clients) and TCP (for the
+Linux client), so make sure you allow incoming traffic if you have
+firewall rules.
+
+This package includes the server and an init script for running
+tnfsd as a system daemon. To start tnfsd at boot, first edit
+/etc/rc.d/rc.tnfsd, read the comments, and change the default user and
+directory if needed. Then add this to /etc/rc.d/rc.local:
+
+  [ -x /etc/rc.d/rc.tnfsd ] && /etc/rc.d/rc.tnfsd start
+
+Depending on how you're using tnfsd, it might make more sense to start
+the service as needed, as an unprivileged user, instead of running it
+as a system daemon.
+
+Usage logging is a compile-time option. By default, it's enabled. If
+you find it too chatty, you can rebuild this with USAGELOG=no set in
+the environment.

+.SH SYNOPSIS
+.sp
+tnfsd \fBdirectory\fP [\fB\-c\fP \fIusername\fP]
+.SH DESCRIPTION
+.sp
+TNFS is a simplified Internet file transfer protocol, designed for
+simplicity and ease of implementation on small systems, such as 8\-bit
+computers. It\(aqs simpler than NFS, SMB, or FTP. It\(aqs similar to TFTP,
+but has features TFTP lacks.
+.sp
+\fBtnfsd\fP is the server for the TNFS protocol. It listens for clients
+on UDP and TCP port 16384. Most 8\-bit clients use UDP, and the Linux
+client \fBtnfs\-fuse\fP uses TCP.
+.sp
+The mandatory \fBdirectory\fP option is the root of the TNFS filesystem
+tree.
+.sp
+The \fB\-c\fP \fIusername\fP option requires \fBtnfsd\fP to be run as
+\fIroot\fP\&. If given, \fBtnfsd\fP will \fBchroot\fP(2) to the \fIdirectory\fP,
+then drop its root privileges and run as the \fIusername\fP user instead.
+.sp
+Even without \fBchroot\fP, \fBtnfsd\fP will not deliberately allow access
+to files outside the \fIdirectory\fP\&. The \fB\-c\fP option is a safety net,
+in case there\(aqs a bug in \fBtnfsd\fP that allows such access (currently,
+no such bug is known of).
+.sp
+Note that \fBtnfsd\fP can be started by a normal user, since it uses an
+unprivileged UDP port. The \fB\-c\fP option won\(aqt work in this case.
+.sp
+\fBtnfsd\fP logs various information to standard error. If compiled with
+\fI\-DUSAGE_LOG\fP, the log includes all mount, umount, and file transfer
+requests including the client IP addresses.
+.SH LIMITATIONS
+.sp
+\fBtnfsd\fP is designed to be simple, so the following list of
+limitations should not be read as complaints or feature requests.
+.sp
+There is no way to run multiple \fBtnfsd\fP instances on the same
+host, not even on a multi\-homed host. The default UDP port cannot
+be changed; neither can the IP address used for binding (which is
+\fI0.0.0.0\fP, aka \fIINADDR_ANY\fP). Also, there\(aqs no concept of virtual
+hosts. If you \fIreally\fP want to run multiple instances, use containers
+or virtual machines.
+.sp
+There\(aqs no way to limit which hosts may access \fBtnfsd\fP using any
+mechanism such as \fBtcpd\fP(8). Firewall rules may be used instead,
+e.g. \fBiptables\fP(8).
+.sp
+There isn\(aqt a way to share a directory read\-only with the current
+\fBtnfsd\fP implementation. However, filesystem permissions can be used
+to prevent the daemon from writing to the shared directory.
