Hi all, I would really appreciate some help with this one if anyone has heard of this happening before. I have installed Samba on Ubuntu Server 8.04 LTS. There are two HDD's one large one for file storage which is mounted as a share. I have setup Samba to have "No authentication" which I believe forces everyone to user "nobody" and group "nogroup". I can see the share fine from my windows XP machine and can read and write to it. Everyone else in the office is on Mac's either OSX 10.4 or OSX 10.5. They can all see the share and read and write to it. server was cut over and went live with all data copied across last Thursday (5-03-09). Since then, two of the Mac OSX (10.5) clients are having a problem with InDesign CS. At least once a day, when they open an InDesign file (from the Samba share) and make changes to it, when they save the file it appears on all the mac clients on the network, as an alias instead of a file. It still has the .indd file extension but it is coloured orange and if any mac client tries to open it, they get an error message stating that the alias cant find the original file. If I browse to the location on my XP machine, I see the file as normal, and I can open the file no worries.If I right click on the file and choose 'properties', all is normal. I then have to copy it back to the original location with a changed file name and it is fine again. everyone can open it again. (the new filename). If I make changes to the file and save the changes (with the original file name) the problem persists. It is only when I create a new file name (save as) that the new file is accessible by all. The original file remains inaccessible from macs. I have since noticed that this can happen even while a mac 10.5 machine has the file open, and it can be fixed by that mac machine by "saving as" and calling it a different file name. All of the MAc osx machine are affected, but I can always (so far) open it with my XP machine. All of the times it has happened have been with Adobe InDesign files (InDesign CS... they insist on using the old version). So far it has only been happening on one OSX 10.5 client with one exception. It has happened once on a different OSX 10.5 client. these are not the only two 10.5 clients that we have on the network. It only happens when you save the file. As I say this has happened five times now and although I have been able to fix it every time in a matter of seconds, it is considered a deal breaker by those around me.(I am the sole IT guy in the office). I have scoured the web with absolutely no results and I have searched through these forums and nothing has turned up. This only happens with InDesign and it didn't used to happen when they were using one of the mac 10.5's as a server. I have been trying to see some pattern of find some clue but have drawn a blank. It appears to be completely random. I would have suspected the problem to be with the client machine except that it has happened once with another client, and it never happened when they used the mac a s a server. It has never happened to the same file twice. here is my Samba conf file, it is the default conf file with these changes: Code: security = share and at the end: Code: [JAJA] comment = Ubuntu File Server Share path = /mnt/JAJA browsable = yes guest ok = yes read only = no create mask = 0755 the next step was to do this: Code: chown nobody.nogroup /mnt/share any help on this or even any form of clue would be greatly appreciated. Thanx in advance Edit: It happens almost on a daily basis now. Edit again: 25/03/2009 The problem has new symptoms: When any of the 10.5 machines moves a .indd file from one folder to another, most of the image links are broken and instead point to the folder location of the new folder that the file has been moved to. The images then need to be re-linked to their respective images. Like I said though, this doesnt happen to all of the images, and doesnt happen to every file.
