Bug 34192 – Unclear when the NET virtual service is provided

• Status: RESOLVED FIXED
• Product: [OLD] Docs-user

[Description Rabbe Fogelholm 2003-11-23 08:26:38 UTC]

The NET virtual service is explained in the document, and in the case of a host
with a single network interface it is fully clear how it works.

However, a host may have multiple interfaces (they would then be listed in
/etc/conf.d/net). In this case, when is the NET virtual service provided? Is it
when ANY of the network interfaces has been brought up, or is it only when ALL
of them have been brought up? This ought to be clarified in the manual.

Please read the docs.  For example running /etc/init.d/net.eth0 without args
will give help - refer to below snippit:

--
'net' Dependency and 'net.*' Services:
    Example:
 
    depend() {
        need net
    }
 
    This is a special dependency of type 'need'.  It represents a state where
    a network interface or interfaces besides lo is up and active.  Any service
    starting with 'net.' will be treated as a part of the 'net' dependency,
    if:
 
    1.  It is part of the 'boot' runlevel
    2.  It is part of the current runlevel
 
    A few examples are the /etc/init.d/net.eth0 and /etc/init.d/net.lo services.

Thanks, now I know where to look. I would have hoped that the "net" virtual service meant all net.ethX interfaces up, not just any of them. But that's another story and I'll find a way to do the necesssary checking.

Still it might be useful IMHO to have this info in the rc-script guide too, it may be used for "offline" reading (that is, not having a working Gentoo system to consult).

Patch to rc-scripts.xml

This patch adds information that a dependency doesn't require all initscripts
to load, only a single one. Would this be sufficient?

[Comment 4 Rabbe Fogelholm 2003-11-27 03:29:50 UTC]

Yes, that looks quite useful.

[Comment 5 Benny Chuang (RETIRED) 2003-11-27 03:48:52 UTC]

then the init script will use one of the available <path>net.eth*</path> scripts, not all!

this would sound better =)

patch looks good

It is actually the rc script that makes the decision, not the init script in
itself.

Can a docdev please review this?

Patch looks good.
