Userland dig/host for lookups against /etc/hosts?
Dear all, my testbed lacks of Ethernet Ports so one machine has no connection to my DNS, no problem, there is something called /etc/hosts I thought. It works if I ping 'hostname', but how can I find out the IP of 'hostname' from the command line? dig and host want to contact the DNS server, also nslookup does, so I think I need a utility which uses the gethostbyname(3) function. Is there one? Unfortunately I can't write one myself, at least not in a reasonable amount of time Thanks, -Harry pgpql7mmH14RD.pgp Description: PGP signature

If you just want local DNS resolution for experimentation you may try running BIND 9 or TinyDNS. Thanks, -Harry -- Best wishes, Alexander G.

If you just want local DNS resolution for experimentation you may try running BIND 9 or TinyDNS. No DNS experiments, I'm very well equiped (authoritative DNS). It's just that my local subnet (productive) has not enough ethernet ports so one test-machine (in another subnet) cannot be connected to the local net and the two other subnets are for testing only, so none routes to my productive net Everything is working fine, just curiosity.. -Harry Thanks, -Harry pgpaEOOjtheY9.pgp Description: PGP signature
