<h1 class="topictitle1">Host Servers port numbers</h1>
|
||
|
|
<div><p>Each type of server has its own server daemon, which listens on
|
||
|
|
a port for incoming client connection requests.</p>
|
||
|
|
<p>There are exceptions to this. For instance, the transfer function over
|
||
|
|
sockets uses the database server daemon; the network drive server uses the
|
||
|
|
file server daemon; and the virtual print server uses the network print server
|
||
|
|
daemon. In addition, the server mapper daemon also listens on a specified
|
||
|
|
port, and allows a client to obtain the current port number for a specified
|
||
|
|
server.</p>
|
||
|
|
<p>Each of the server daemons listen on the port number that is provided in
|
||
|
|
the service table for the specified service name. For example, the network
|
||
|
|
print server daemon, with the initial configuration that is provided, listens
|
||
|
|
on port number 8474, which is associated with service name 'as-netprt.' The
|
||
|
|
server mapper daemon listens on the well-known port. The well-known server
|
||
|
|
mapper port number is 449. The well-known port number is reserved for the
|
||
|
|
exclusive use of the Host Servers. Therefore, the entry for the 'as-svrmap'
|
||
|
|
service name should not be removed from the service table.</p>
|
||
|
|
<p>The port numbers for each server daemon are not fixed; the service table
|
||
|
|
can be modified by using different port numbers if your installation requires
|
||
|
|
such changes. You can change where the port number is retrieved from the iSeries™ Navigator
|
||
|
|
system properties connection tab. However, the service name must remain the
|
||
|
|
same as that shown in following tables. Otherwise, the server daemons cannot
|
||
|
|
establish a socket to accept incoming requests for client connection.</p>
|
||
|
|
<p>If a new service table entry is added to identify a different port number
|
||
|
|
for a service, any pre-existing service table entries for that service name
|
||
|
|
should be removed. Removing these entries eliminates the duplication of the
|
||
|
|
service name in the table and eliminates the possibility of unpredictable
|
||
|
|
results when the server daemon starts.</p>
