.TH EXECNET 4
2 
.SH NAME
3 
execnet \- network interface to program execution
4 
.SH SYNOPSIS
5 
.B execnet
6 
[
7 
.B -n
8 
.I name
9 
]
10 
[
11 
.B netdir
12 
]
13 
.SH DESCRIPTION
14 
.I Execnet
15 
presents a network protocol directory
16 
(see, for example,
17 
.IR ip (3))
18 
called
19 
.IB netdir / name
20 
(default
21 
.BR /net/exec ).
22 
.PP
23 
Once the protocol directory exists, dialing
24 
(see
25 
.IR dial (2))
26 
strings of
27 
the form
28 
.IB name ! cmd
29 
will connect to a newly executed instance of
30 
.IR cmd .
31 
.SH EXAMPLE
32 
.I Execnet
33 
can be used to connect to instances of
34 
.IR u9fs (4)
35 
running on other hosts:
36 
.EX
37 
    g% execnet
38 
    g% srv -m 'exec!ssh ny start-u9fs' ny /n/ny
39 
.EE
40 
This example assumes that the remote command
41 
.B start-u9fs
42 
executed on
43 
.B ny
44 
will start
45 
.I u9fs
46 
appropriately.
47 
For example, it might be:
48 
.EX
49 
    ny% cat start-u9fs
50 
    #!/bin/sh
51 
 
52 
    u9fs -na none -u $USER -l $HOME/tmp/u9fs.log
53 
    ny%
54 
.EE
55 
See the
56 
.IR u9fs (4)
57 
man page for more information.

.SH BUGS

Almost certainly:
66 
.IR execnet
67 
has only been tested as in the example shown.
