I'm currently using the technique to providedifferent views of my network depending on whether access is coming from an internal address or an external address. Perhaps I am not fully understanding the depth of the problem.I'm not an expert on bind 9 views, but I want two sibling processs to get different network views. can I do that on a freebsd6.1 machine using stock gethostbyname() from libc?I waited to suggest this based on whatever additional information you provided, but it sounds like this could work, with the condition that you be able to identify the IP addresses (or better yet, ranges) that the different categories of process will be assigned to in advance; or that you could configure named.conf (or an include file) on the fly. And of course, all THIS is presupposing that you can get both views (inside and outside) on the same nameserver, that is available to both sets of processes.
the machine is running a proprietary name server. but I want to alter resolv.conf to bypass this and go elsewhere for some processes. The processes in this machine are on one of two addresses but there is no correlation between which address they are bound to and how I where I want them to go for name resolution. Anyhow, I've yet to find a way to make gethostbyname bind to a particular
address.It is intersting that people are suggesting tons of really complicated solutions involving loading essoteric softwere or setting up complicated virtual machines when listenning to a simple environment variable will do the trick.. For comparison, the nsswitch code in current ALREADY listens to an environment variable
for an alternate name for /etc/nsswitch.conf..
i.e. nsdispatch.c: path = getenv("NSSWITCH_CONF");
So, not trivial, but could possibly solve your problem. Doug
