Hmmm, interesting. Normally if you don't have anything front of the ":", it assumes localhost. In your case, are you saying this didn't happen before when you have it an invalid hostname? Also, are you sure it's not DNS? Sometimes your local resolver automatically appends domainnames in your search. And some admins setup a "default" IN A record to be 127.0.0.1 on any lookup for a domain that doesn't properly resolve. I know that's kinda outside of your issue, but it's still something to check "just-in-case." Anyhoo, my typical "Golden Rule of Thumb" is to always export with the system name as part of the share. I find it avoids a lot of issues for myself, and it would in this case as well. I.e., only the system with the sharename that has the systemname could be mounted, and anything else would fail. Especially when it comes to systems with NFS automounts that host home directories that also share via Samba. I _avoid_ the default "homes" share, and explicitly setup a share that points to only an specific local path where user home directories could be located on that specific system. Now Samba does have good automounter support, and newer SMB has a DFS renaming approach, but it's still a nice option that works with any legacy setup (even when you have automounter and/or DFS in your Samba config). See page 1101 of "Appendix A" in "Samba Unleashed" on this -- as well as pages 1100-1102 for a general discussion of integration of NIS Automounter maps with Samba (non-DFS). It's circa 2000, but is still my recommended approach, even when Samba has been built with automounter and/or SMB DFS capability. -- Bryan J. Smith mailto:b.j.smith at ieee.org
