Bug 110325 – Possible to define multiple $gateway within /etc/conf.d/net?

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Roger 2005-10-24 07:37:35 UTC]

I have a laptop and use both a nic (/etc/init.d/net.eth0) and a wireless pcmcia
card (/etc/init.d/net.eth1).

Everytime I decide to unplug my nic cable and run around the house using the
wireless pcmcia card, I usually have to edit the /etc/conf.d/net and change the
$gateway variable to show gateway="eth1/192.168.2.1" instead of the usual
gateway="eth0/192.168.2.1.

Of course, specifying eth1 to use dhcp would rectify this issue, but I want to
keep things statically assigned for personal reasons.

Could /etc/init.d/net* be modified to read an optional syntax for the $gateway
variable such as gateway="eth0,eth1/192.168.2.1"?

I've searched quite a bit for a solution for this issue and have yet to find
anything except something called "netplug"

Reproducible: Always
Steps to Reproduce:
1.
2.
3.



Expected Results:  
/etc/init.d/net* to read in the users preferred $gateway variable for which ever
nic device the user wants to use.

or extend the gateway var to behave like others ...

gateway_eth0="..."

Or use the new syntax, which is documented in /etc/conf.d/net.example

routes_eth0=( "default via 192.168.0.1" )
routes_eth1=( "default via 192.168.0.1" )

Of course, if both were active then you would get errors, so you have 2 choices
1) use metrics
routes_eth0=( "default via 192.168.0.1 metric 0" )
routes_eth1=( "default via 192.168.0.1 metric 2" )

2) use baselayout-1.12.0 and set RC_AUTO_INTERACE="yes" in /etc/conf.d/rc so we
handle metrics for you

Edited /etc/conf.d/net to show:
routes_eth0=( "default via 192.168.2.1" )                                      
                             
routes_eth1=( "default via 192.168.2.1" )

I now get this output on restarting net.eth1:
# /etc/init.d/net.eth1 restart
 * Caching service dependencies ...                                            
                                        [ ok ]
 * Bringing eth1 down ...                                                      
                                        [ ok ]
 * Bringing eth1 up (192.168.2.4) ...                                          
                                        [ ok ]

                              [netmask N] [mss Mss] [window W] [irtt I]
                              [mod] [dyn] [reinstate] [[dev] If]
       inet_route [-vF] add {-host|-net} Target[/prefix] [metric M] reject
       inet_route [-FC] flush      NOT supported


But, hey.. .it works.  The error seems to be caused by my orinoco pcmcia
wireless nic card.  So I augmented /etc/conf.d/net to show:

gateway="eth1/192.168.2.1"
routes_eth0=( "default via 192.168.2.1" )
#routes_eth1=( "default via 192.168.2.1" )

As you can see, I reverted to using the old "gateway=" syntax for the wireless
net.eth1 device and using the new "routes_eth0" syntax for the standard nic
interface.  Things seem to be working without errors now.

(btw, submitted two bugs today and have experienced exceptional friendly
customer service with excellent feedback!)

btw, I'm seeing this within the handbook-x86.xml?part=1&chap=8 now too.  I
either missed it or the feature was just documented within the past month or so. :-)

Great work. Thankyou!
