hi folks!! i was wondering... no this is no way related to clustering.... its more or less related to network load balancing. i got 2 pcs and on each pcs i got 2 nic cards. i was wondering how can i make the cards go live. what i mean is suppose if one card fails to work!! is there any mecanism that the other card picks up the same network id number and same mask. viz. the 3com 100mbit card with n/w id 192.168.1.2 and snm 255.255.255.0 and another 3com 100 mbit card with another n/w id 192.168.1.3 and snm 255.255.255.0 what i actually want to do is this. i expt shut down one interface. i.e 19...2 and i want the nic card 192...3 to use the n/w id 192....2 when its assigned 19...3 ... is this kind of tweaking possible. if so how?? i was just wondering. tho all the 4 nic cards are brand new 3com 100 mbit cards, there is no qstn of them being down. but whet if they go dowm :-p cheers!!
