Hi everyone,appreciated.
Before you read the following please keep in mind, that I appreciate the
work you guys do in your spare time for the sake of us. It is a great
help. And even if XWLAN is not perfect it is a very useful tool for
operating a WLAN card.
Yes, I played around with 2.14 some days ago, just to find out that itI am sorry, but having two interfaces configured to the same subnet is wrong. If you mean that you disable one of either interface, this would be ok. But it is definitely not sufficient to just "not use" one of either interface. The IP stack will not care for if you don't use one of two interfaces - exactly one of two will just always win and the other will never be used.
has a big design problem: Deleting an interface (e.g. LAN) when it is in
the same subnet a the other (e.g. WLAN) is just wrong. Because:
+) In my situation (never using both interfaces at the same time) it is
necessary to have them configured to make TCPBEUI work. So it should be
possible to turn this feature off.
+) Even if it is necessary to delete one of the interfaces it makes theThat is correct and I hope I will be able to fix this route issue.
TCP/IP-stack unusable because if it turns off the previously configured
interface it does not update the routes - so no interface does work:
-) Let's say lan0 is LAN, lan1 is WLAN, lan0 is configured"Do nothing is definitely not an option.
-) We turn on WLAN - XWLAN gets configuration for lan1 using DHCP
-) Routes are configured for lan0, so the ones for lan1 aren't there
-) XWLAN detects the "conflict" and deletes lan0
-) The routes for lan0 are still there - nothing does work
-) XWLAN "thinks" it has completed it's work
The correct behavior would be:
1) XWLAN configures WLAN interface (either statically or with DHCP)
2) XWLAN detects the "conflict"
3) If the LAN interface should be deleted (one of three options: "Delete
LAN if", "Delete WLAN if", "Do nothing"): do the following:
4) Delete WLAN interface (yes!)Hmmm. I did not know that this has to be explicitely set. How would I do that ?
5) Flush all routes and arp table (route flush or route -fh and arp -f)
6) Delete the LAN interface
7) Configure WLAN interface (statically or using DHCP)
7a) (Now the routes should be OK.)
8) Set "hostid" to the address of the newly configured if (WLAN)
9) Run rfcaddr for TCPBEUINote that NetBEUI is currently ot handled by XWLAN, so you would have to do that with the script feature.
Off course this does take a longer time (two times waiting for the DHCPFor testing I implemented something different, at least for the default route. If the WLAN interfaces is to be kept, the default route is saved, deleted, then LAN is deleted, then default route is reset - et voila: the defalt route is attached to the WLAN interface. I intend to cache _all_ routes for the cabled interface and restore them all on the correct interface, so network and hostroutes would also be handled properly. The only drawback is that I cannot do that for the way back (wireless to cabled). Here the setup script is to setup all routes properly again.
lease), but the result is that it does actually work.
P.S. All the time I spent to get XWLAN working correctly was more orI am sorry to hear that. Did you post a request to netlabs.org on this ?
less useless as my mini-PCI "IBM High Rate ..." still chocks up when
sending more than just a few KB (XWLAN shows "No Card"). But this is a
driver problem...
