Hello list, We're migrating our whole network to Linux. The process involves a period of time in which there will be Linux clients and windows clients mounting remote shares from a NT server. The access is working fine, But file locking isn't working properly. I'll expose situations tested: Cases 1) Client A: Windows using Excel Client B: Windows using Starcalc (staroffice) This situation is handled perfectly. No linux involved. 2) Client A: Windows using Starcalc Client B: Linux using Starcalc Its working right. Starcalc recognizes that file being used And the second starcalc sees the file just read only. 3) Client A: Windows using Excel Client B: Linux using Starcalc There is no knowledge that any client has opened the document, users may modify the document simultaneously, and also, both clients will be able to save the document. But one will save his changes and the other one will save the same file with different data. This situation is causing data loss and file corruption. I tried to mount the remote share as smbfs and cifs. And the same result. I've been reading that cifs only applies to w2k and above. Our servers are NT Do I get any feature using cifs instead of smbfs? Thanks. -- Francisco Jos? Fern?ndez Rivera Departamento de Tecnolog?a (Redes) Riu Hotels & Resorts Palma de Mallorca Espa?a
