Installing a daemon under inetd
The usual way to install a daemon is to either run it from the bootstrap
command file (for example /etc/rc) so that it runs continuously, or
to set up the internet daemon (inetd) to run it when a call comes
in.
There is a csh script to do all this for BSD systems, which should
be run from the directory in which you have compiled the daemon.
Copy the daemon program or shell script ( httpd in this example) into
a suitable directory such as /usr/etc/httpd. Protect it from anyone
writing to it except root.
Put "http" in the /etc/services file, or use the name of a specific
service of your own if you want to use have a special port number.
(Exceptions: on a NeXT, see using the NetInfomanager . On any machine
running NIS (yellow pages), see specicial instructions ).
For example,
<![CDATA[www 80/tcp # WorldWideWeb server
]]>Put a line in the internet daemon configuration file, /etc/inetd.conf.
For example,
www stream tcp nowait nobody /usr/etc/httpd httpd -l /private/adm/httpd-log.txt
(That was all one line.) Here "www" is used as a link between the
services file and inetd.conf: it could have been any identifier. "nobody"
is the user name under which you want the daemon to run, which determines
what privileges it has for example to read data. The inted.conf format
varies from system to system so copy the format of other lines in
your version.
Note: there seem to be, on the NeXT at least, a limit of 4 arguments
passed across by inetd!When you have updated inted.conf, find out
which process is running inetd, and send it a "HUP" signal. On BSD
unix (For system V, use ps-el for ps aux) this looks like:
<![CDATA[
> ps aux | grep inetd | grep -v grep
root 85 0.0 0.9 1.24M 304K ? S 0:01 /usr/etc/inetd
> kill -HUP 85
>
]]>
Also remember for httpd:
You must make or copy a rule file /etc/httpd.conf, unless you have
used the -r option to change its location, or -R to disable it.
The -r option tells the daemon which rule file to use. See rule files
.
If a log file is required, make sure that the user name under which
the daemon is run (the 5th field in the line above) has the right
to write the file.
Test the server with the line mode browser by giving its address explicitly:
<![CDATA[ www http://myhost.dom.ain:80/junkdocumentname
]]>If it doesn't work, you have probably missed something. See notes
on debugging .
