someone told me that this piece of network hardware (netapp NAS) has a security setting such that it can only be accessed by hostname, not by IP address. I don't understand, as I thought DNS resolved the hostname to an address on the connecting client's side, then at protocol level always used the raw address, so how can this 'security' measure be possible?
"the NAS won't allow for access by IP, i.e.
\\x.y.z.w\SHARE. Instead, you have to use
\\hostname\SHARE after creating the DNS entry.
edit: it appears to be a CIFS thing: you can access the nas from linux via NFS by address, but not on windows via CIFS.
