     This is defining a new service named "elegans" which runs on
     port 5000.  You can change this symbolic name to anything you
     like.  If you have multiple acedb databases running, give each
     one a distinctive name and port number.  Avoid using any port
     numbers that are already mentioned in the file.

   b) Find the file /etc/inetd.conf, and add the following line:

    elegans  stream  tcp wait acedb  /usr/local/acedb/bin/sgifaceserver
            sgifaceserver /usr/local/acedb/elegans

    This is all one line, but has been word-wrapped to fit.

    The first field refers to the service named "elegans" that you
    defined in /etc/services and is necessary for inetd to associate
    the service with the proper port number.  Modify as you see fit.

   c) Tell inetd to reread its configuration files.  Use "ps" to find
      the ID of the inetd daemon like this:

      # ps -elf | grep inetd
      140 S root       121     1  0  68   0    -   475 do_sel May11 ? 00:00:00 /usr/sbin/inetd

      and use "kill -HUP" to tell the server to reread inetd.conf
      (this must be done as root):

      # kill -HUP 140

You should now be able to communicate with the server using saceclient
or ace.pl.  If it's not working, look in the following log files for
helpful error messages:

      /var/log/messages
      ~acedb/elegans/database/log.wrm
      ~acedb/elegans/database/serverlog.wrm

2) Configuring for xinetd:

  a) Find the file /etc/services, and add the following line to the
      end of the file:

     elegans   5000/tcp

     This is defining a new service named "elegans" which runs on
     port 5000.  You can change this symbolic name to anything you
     like.  If you have multiple acedb databases running, give each
     one a distinctive name and port number.  Avoid using any port
     numbers that are already mentioned in the file.

  b) Find the directory /etc/xinetd.d.  Create a file named after
     the service chosen in (a) containing these contents:

        # file: elegans
	# default: on
        # description: C. elegans acedb database
	service elegans
	{
	        disable                 = no
	        protocol                = tcp
	        socket_type             = stream
	        flags                   = REUSE
	        wait                    = yes
	        user                    = acedb
	        group                   = acedb
	        log_on_success          += USERID DURATION
	        log_on_failure          += USERID HOST
	        server                  = /usr/local/acedb/bin/saceserver
	        server_args             = /usr/local/acedb/elegans
	}

      Change the line "service elegans" to be the symbolic name chosen
      in (a).

   c) Tell xinetd to restart.  Use "ps" to find the ID of the xinetd 
	daemon like this:

      # ps -elf | grep xinetd
      140 S root       457     1  0  69   0    -   557 do_sel Mar09 ? 00:00:21 xinetd

      and use "kill -HUP" to tell the server to reread inetd.conf
      (this must be done as root):

      # kill -HUP 140

You should now be able to communicate with the server using saceclient
or ace.pl.  If it's not working, look in the following log files for
helpful error messages:

      /var/log/messages
      ~acedb/elegans/database/log.wrm
      ~acedb/elegans/database/serverlog.wrm
