I have edited /etc/resolvconf/resolv.conf.d/base and added entries like: mylocalserver 10.2.6.33 upon restart I can see it is in the resolv.conf file, however if I try to check if it works by opening up a terminal and entering ping mylocalserver I get "unknown host" messages. This is a closed network with local servers and no DNS, so I have to hand map the server to ip address. Is this the correct format for the entries? I have a TAB as whitespace separator.
