Only on match of that outer boundary checking of the idividual hmm... yeah that could cause a bit of problem especially since we run 4 nics with unique networks in each and various guests address them as they are configured.. would not do for it to see for example our 38 net and 39 net each a /24 as one range... would severely mess up vpns and things.. ok so ill just have to plan for no more than 16 ips per guest which severely increases our license outlay for a program we run in each guest. we ultimately need to be able to safely and quickly address between 50 and 100 ips per guest to keep our costs down. > addresses or the guest is done. > Mostly missing is the handling of broadcast... > > Bruno > ___ > Vserver mailing list > Vserver@list.linux-vserver.org > http://list.linux-vserver.org/mailman/listinfo/vserver > -- Chuck "...and the hordes of M$*ft users descended upon me in their anger, and asked 'Why do you not get the viruses or the BlueScreensOfDeath or insecure system troubles and slowness or pay through the nose for an OS as *we* do?!!', and I answered...'I use Linux'.

I did some coding in that direction, but patch is not finished yet. Hopefully I will get some more time after next week do continue coding on it. My direction is assigning address elements to guests, either single addresses or groups of addresses as range or mask. When there is more than a single such item, on additional is created that itentifies the complete range contaning the addresses of a guest. Thus two guests with 20 IPs spread over two different /24 networks wil be seen as a single range for most check wether IP is part of the guest's address-space. Only on match of that outer boundary checking of the idividual addresses or the guest is done. Mostly missing is the handling of broadcast...
