I have a local (192.168.0.xxx) machine that can be accessed over the local network via Putty (without Kerberos) and via MobaXterm. I added an alias for the target machine in the Windows etc/hosts file (which successfully facilitates pings to it by name) and added an entry for that machine in my router's DNS Host Mapping index (which had no effect on anything that I'm aware of).
3c58.com IS routable on the Internet, but the local machine: Level10.3c58.com is not. I'd like kerberos to create tickets for the local machine, but I'm out of ideas on how to get that to happen under present circumstances. Is there some way to convince Kerberos to look at the hosts file on windows or somehow tap the router's domain name server setting (I think they're being ignored at present).
