Convert with: +. +.\" rst2man.py tnfsd.rst > tnfsd.1 +. +.\" rst2man.py comes from the SBo development/docutils package. +. +.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. +.SH COPYRIGHT +.sp +See the file /usr/doc/tnfsd\-20201019/COPYING for license information. +.SH AUTHORS +.sp +tnfsd was written by Dylan Smith. +.sp +This man page written for the SlackBuilds.org project +by B.
