sendfiled is a server process (daemon) for the Simple Asynchrnous File Transfer (SAFT) protocol. The
server is normally called by inetd (8) and receives files or messages sent by SAFT-clients to the. Files
are stored in the recipient's spool and messages are written to the recipient's terminals.
The -4 and -6 options explicitly force IPv4 or IPv6 connections. By default, the program will try to
resolve the name given, and choose the appropriate protocol automatically. If resolving a host name
returns both IPv4 and IPv6 addresses, sendfiled will try to use the adresses in the order they are
returned by the resolver.
If the -d option is specified, debugging information is written to /var/log/sendfiled.dbg.
If the -f option is specified, sendfiled prints the free disk space on /var/spool/sendfile and
terminates.
If the -q option is specified, sendfiled processes once the outgoing spool and terminates.
If the -Q option is specified, sendfiled starts an outgoing spool daemon, which runs in an endless loop
in the background.
On startup sendfiled reads its configuration file /etc/sendfile.cf, but you can specify with -cconfigfile an alternate configuration file.
sendfiled is also an O-SAFT server, which means authenticated clients can fetch files. See fetchfile (4)
for details.
sfdconf is the sendfiled configuration helper program. It has its own usage help, just type sfdconf-h
