netconfig(ADM)
netconfig --
configure networking products
Syntax
netconfig [ -ar chain ]
netconfig [ -ce chain_element ]
netconfig [ -lsn ]
Description
netconfig configures and enables network products.
netconfig provides a standard way to combine networking
products together to form a networking system from compatible networking
components. By default, it is only executable by root.
netconfig assembles compatible sets of networking products into
functional groups called chains. Configuring (adding) a chain will do
everything necessary to enable the functions of the component products in
the chain within a single command. Deconfiguring (removing) a chain
through netconfig does everything necessary to disable the
function of the component parts of the chain also in a single command.
A chain consists of a top level product, and one or more lower layer
networking products that together produce a functional networking
system.
netconfig is most often used interactively through the
SCO Visual Tcl
graphical
interface, or at the command line. When the graphical
interface is used,
netconfig presents the user with a list of the currently
configured chains as part of the main screen.
netconfig, when used non-interactively, is designed to be used
as an engine underneath a higher level user interface program, whether
graphical or character oriented.
For more information on using the graphical interface, see
``Configuring network connections'' in Configuring Network Connections.
netconfig and netconfig-compatible products
place their information in the directory /usr/lib/netconfig.
The /usr/lib/netconfig directory has the following subdirectories:
info-
This directory contains files that describe the product information.
init-
This directory contains all the initialization scripts and all the
default value files.
remove-
This directory contains product removal scripts.
reconf-
Directory used by netconfig; contains reconfigure scripts
for each product.
src-
Directory used by netconfig.
chains-
File used by netconfig.
netconfig takes the following options:
-a chain-
Add a chain specified by the user. Designed as part of the command line
engine, this option will perform an add (call the add scripts) without any
user intervention. If the chain passed in is invalid, then netconfig
will return an error and output a single-line error message.
Chain names are specified with a single word comprised of the names of
each element in the chain separated by ``#'' characters:
top#middle ... #bottom.
-r chain-
Remove. netconfig
removes the specified chain.
Chain names are specified with a single word comprised of the names of
each element in the chain separated by ``#'' characters:
top#middle ... #bottom.
A single complete, valid chain name must be passed to netconfig
with the -r option.
-c chain_element-
Reconfigure an element in a chain. Requires a chain name and element as
arguments.
-e chain_element-
Element. Output the list of elements in the given chain that support
reconfiguring.
-l-
Link. netconfig
relinks the kernel and installs it without asking (suppresses the link
kernel prompt) if changes are made that require relinking the kernel.
-n-
Never link. netconfig
never relinks the kernel (suppresses the link
kernel prompt) if changes are made that require relinking the kernel.
-s-
Status. netconfig
prints a list of the currently installed chains and exits.
This is intended for use in shell scripts that are trying to remove
all chains associated with their product.
