fspd, in.fspd - File Service Protocol (FSP) server


Exit Codes


fspd [-f configfile] [-p port] [-i] [-v|-V] [-t timeout] [-X] [-d directory] [-F ] [-T temporary directory] [-l logfile] [-P pidlogname] [-b bandwidth] [-s packetsize]


fspd is the server for an anonymous-ftp style archive called FSP. The main features of this service are: connection-less model, communication robustness, server resource protection, inter-client protection, and user friendly interface. Please read the INFO file bundled with the FSP source for more information.


-f May be used to specify an alternate configuration file.

-i Use when fspd is running from inetd.

-p port May be used to specify an alternative port.

-d directory May be used to specify an alternative home directory.

-v | -V Show server version.

-X Turn on debuging.

-t timeout Set server inactivity shutdown timeout for running in inetd mode. Default is 120 seconds. When -d is used, this timeout works in normal mode also (usefull for debuging of memory leaks).

-F Run fspd in foreground, do not daemonize.

-T directory Set server temporary directory used for uploading. This directory can be outside FSP home directory since it is not directly accessible by clients. Using directory inside FSP home is not a security risk.

-l logfile Write log output to file.

-P pidlogname Write pid to the given file name.

-b bandwidth Enable bandwidth limiting. Limit output to bandwidth bytes per second.

-s packetsize Sets maximum allowed or prefered packet’s payload size. Server must support packets up to 1024, but may prefer to send smaller packets. It may accept packets over 1024 bytes. Default value is 1460 bytes. All networks must be able to transfer 500 bytes (RFC requirement).


.FSP_OWNER Used to indicate the ownership of a directory. This file contains lines with the same syntax as host lines in fspd.cnf but without keyword host on start of line. Host types D, I, N can be used to restrict access to specific directory. Owners are marked with host type O.

.README A text file that is sent to the client when the directory is entered giving information about the directory. It can only be hand created by the site administrator at this time. This text file should be no more than 1022 bytes in size. Any data above this limit will be silently ignored. Name of this file can be changed in server configuration file.

.FSP_OK_DEL Existence of this file in a directory grants non-owner machines the permission to delete items from this directory.

.FSP_OK_ADD Existence of this file in a directory grants non-owner machines the permission to add items to this directory.

.FSP_NO_LIST Existence of this file removes right to list a directory from non-owner.

.FSP_NO_GET Existence of this file in a directory means that files in that directory cannot be read by public, i.e. they are private.

.FSP_OK_MKDIR Existence of this file in a directory grants non-owner machines the permission to create subdirectories under the current directory.

.FSP_OK_RENAME Existence of this file in a directory grants non-owner machines the permission to rename files in directory.

.FSP_OK_PASSWORD Password required for non privileged access.

.FSP_OWNER_PASSWORD Password required for privileged access. You must have also your IP listed in .FSP_OWNER file.

.TXXXXXXXXXXXX Transient temporary file in the FSP temporary directory used for file uploading.

.GXXXXXXXXXXXX Transient temporary file in the FSP temporary directory used for file downloading through the fgrab command.

fspd.conf A file containing control information about how specific features of the server are to be used. See the example.conf file for explicit details.

.FSP_CONTENT File used to cache directory listing. Such files are normally created on demand in each directory that fspd exports.


SIGUSR1 Server dumps stats to file specified as dumpfile in configuration. This file must be writeable by server or server must have rights to create it.

SIGINT | SIGTERM Server performs cleaup and exits. All connected clients will be disconnected. Because FSP is stateless protocol, if you start server later, clients can continue without breakage.


1 configuration or command line invocation error.

2 can not open/bind server socket

3 can not change uid to runuid

4 can not change gid to rungid

5 out of memory

6 can not change directory to homedir

7 select() error
