Re: Default-Routing problems

[John Mahoney <jmahoney waav com>]

Colin,

I like this idea.  It definitely would be helpful for ethernet and wifi devices where the user only wants to connect to the lan and not have a default route set.  It may have relevance to a GSM or CDMA connection(PPP connections in general) if the user is only using that connection to run a vpn over, but I am not sure.  

With that being said it is not really my decision to make and the more people who show interest in a feature such as this the better chance for it to be implemented. I personally have wanted a feature such as this and priority of interfaces for about two years, but I can not complain because NM has continued to improve for the better and this may still be an edge case for user needs.  I do feel this feature will continue to become more and more relevant in the future.

Following up to my previous post:

Here is an idea for an small enhancement to NetworkManager which would
solve my particular problem, and perhaps be generally useful for other
users with 'non-standard' use cases.

1. Define a new flag 'Local only' for each network connection. By
default, this flag is unset and does not affect the existing behaviour
of NetworkManager.

2. when NetworkManager is choosing which connection to use for the
default route, any connection with the 'Local only' flag set will not be
chosen.

A connection with this flag set can still be started automatically and
it will have a routing table entry for its particular IP subnetwork as
usual.

This flag should be set for any network connection that you are only
using to access local resources (e.g. printers and file shares).

I know of cases where wired-Ethernet and WiFi connections are used in
this manner. I don't know if this flag would be sensible on GSM or CDMA
connections (but I suspect not).

By the way, I notice that Windows Vista detects whether a given WiFi
connection has internet access or not. I don't know how they detect
that, but I am not proposing the NetworkManager tries to do it -- a
manual setting is all I am asking for.

Any comments?
