-files opened for writing will send the data of write operations -to the command's standard input. -.Pp -The -.Pa tcp -namespace takes a slash separated hostname and a port and -creates an open TCP/IP connection. -.Pp -The -.Pa tcplisten -namespace takes a slash separated hostname and port and creates a TCP/IP -socket bound to the given hostname-port pair. -The hostname may be -specified as "ANY" to allow any other host to connect to the socket. -A -port number of 0 will dynamically allocate a port, this can be -discovered by calling -.Xr getsockname 2 -with the returned file descriptor. -Privileged ports can only be bound to -by the super-user. -.Sh "CONFIGURATION FILE" -The configuration file contains a list of rules. -Each rule takes one line and consists of two or more -whitespace separated fields. -A hash (``#'') character causes the remainder of a line to -be ignored. -Blank lines are ignored. -.Pp -The first field is a pathname prefix to match -against the requested pathname. -If a match is found, the second field -tells the daemon what type of object to create. -Subsequent fields are passed to the creation function. -.Bd -literal -# @(#)portal.conf 5.1 (Berkeley) 7/13/92 -tcplisten/ tcplisten tcplisten/ -tcp/ tcp tcp/ -fs/ file fs/ -pipe/ pipe pipe/ -.Ed -.Sh FILES -.Bl -tag -width /p/* -compact -.It Pa /p/* -.El -.Sh EXAMPLES -Display the greeting of the -.Fx -.Tn SMTP -server. -.Pp -.Dl "head -1 /p/tcp/mx1.freebsd.org/smtp" -.Pp -Implement a (single-threaded) echo server: -.Bd -literal -offset indent -while : -do - (exec 3<>/p/tcplisten/ANY/echo && cat -u <&3 >&3) -done -.Ed -.Pp -Gather data from two sources. -Verify that two remote files are identical: -.Bd -literal -offset indent -diff -q '/p/pipe/usr/bin/fetch -o - \\ - ftp://ftp1.freebsd.org/pub/FreeBSD/README.TXT' \\ - '/p/pipe/usr/bin/fetch -o - \\ - ftp://ftp2.freebsd.org/pub/FreeBSD/README.TXT' -.Ed -.Pp -Scatter data to two sinks. -Record a remote -.Tn CD -.Tn ISO -image and calculate its checksum: -.Bd -literal -offset indent -fetch -o - ftp://ftp5.freebsd.org/.../disc.iso | -tee '/p/pipe/usr/local/bin/cdrecord -' | -md5 -.Ed -.Pp -Create an -.Tn XML -view of the password file: -.Bd -literal -offset indent -ln -s '/p/pipe/usr/local/bin/passwd2xml /etc/passwd' \\ - /etc/passwd.xml" -.Ed -.Sh SEE ALSO -.Xr mount 2 , -.Xr unmount 2 , -.Xr fstab 5 , -.Xr mount 8 -.Rs -.%A "W.
