net_server mixes up interfaces in settings file

[pulkomandy]

/system/settings/network/interfaces:

interface       /dev/net/usb_ecm/0 {
        address inet {
                address 192.168.4.2
                mask    255.255.255.0
        }
}
interface       /dev/net/rtl81xx/0 {
        address inet {
                auto_config     true
        }
}

USB interface currently not connected. Static IP gets assigned to the second interface. I have to reset that one in Network preferences everytime, which does not seem to have any effect on the setting file. At next reboot, the problem is back.

Probably a duplicate of #6351?

[pulkomandy]

No, #6351 is/was exclusively about the DNS information, which isn't specific to a device, but extracted from DHCP fr each device, leading to some understandable confusion.

Here the setting entries are not bound to the right card, which is a more important bug.

I'm tagging this on here, rather than in a new ticket, because I'd guess it's related. Apologies if I'm wrong. I've recently installed Beta1 (hrev52295+129), and find that it insists on using DHCP even though I want Static! It seems to ignore the ...settings/network/interfaces file, which has:

interface	/dev/net/iprowifi4965/0 {
	address	inet {
		address	192.168.1.6
		mask	255.255.255.0
		gateway	192.168.1.1
	}
}
interface	/dev/net/rtl81xx/0 {
	address	inet {
		address	192.168.1.16
		mask	255.255.255.0
		gateway	192.168.1.1
	}
}

Despite that file, it always assigns an arbitrary DHCP addrees on boot, and the Preferences correspondingly says 'DHCP'. If I change it to Static, with the desired IP, I just lose the connection, and at next boot it's back to DHCP. Strangely the file's timestamp indicates it was rewritten, but the contents seem to remain as I set them above.

I should add that I normally connect via WiFi, but when I connect a cable it behaves the same.

see https://dev.haiku-os.org/ticket/14626 as well. It was closed but I think that was premature.

Yes, it's still a problem in hrev53552. Switching DHCP to Static works while running, but upon reboot, it's back to DHCP. Looking at the /boot/system/settings/network/interfaces it has two network card entries, and picks the wrong one - did someone put != instead of == in a string comparision? The workaround is to delete the interfaces file then use the Preferences, which will recreate it with just one network card.

[Pete]

Hmm. In contrast -- running hrev53511 -- I don't see this anymore. Both my wifi and wired connections are set as static, and that's the way they connect. Maybe when I did the upgrade somehow I set the interfaces file correctly. Anyway it just shows one entry for each card.

OTOH, although I have a 'wireless_networks' file pointing to my local router, it doesn't connect automatically as I would expect. I have to select it from thewifi menu.

[AGMS]

My trouble was that there were two network card entries, but only one network card. One entry was for a different network card that had been present earlier. One entry was DHCP, the other static. Easiest to test when you switch virtual network cards in VirtualBox.

[Pete]

Ahh. apparently I misunderstood. One of the entries was for a no-longer-existing card? I guess the system should be able to figure out that card was gone!

Replying to kallisti5:

see https://dev.haiku-os.org/ticket/14626 as well. It was closed but I think that was premature.

The bug itself is no bug, but intended behaviour. Whether that makes sense or not, I left open for discussion, but no one cared so far :-)

In any case, the behaviour described in this ticket is certainly a bug.

[axeld]

Fixed in hrev53582.
