1Use the following configuration file, tcp.1.conf:
2
3tcp/	tcp	tcp/
4
5Now mount it, and cat the contents of /p/tcp/localhost/daytime:
6% mkdir portal
7% mount_portal /usr/share/examples/mount_portal/tcp.1.conf `pwd`/portal
8% cat portal/tcp/localhost/daytime

11Philosophy:  With a pathname of <path to mountpount>/tcp/a/b[/priv],
12the portal daemon opens a connection to host a, port b.  If /priv
13is specified, the socket will be created via rresvport(), rather
14than socket().
15
16For the above example, we open a connection to the daytime port
17(port 13, according to /etc/services), and read data.

20Advanced usage:  finger
21Using the already-mounted portal file system, open a connection
22to the finger daemon, and do a finger.  Use the simple C program
23in fing.c in this directory.

38Philosophy:  fing.c opens portal/tcp/localhost/finger as a
39read-write file.  First, we write the username for the finger (or
40a blank line to see all users), then we read the results sent
41over the socket.
