I had newly installed Ubuntu 10.10 and was trying to communicate with my Synology DS109 network-attached storage (NAS) unit. I had previously resolved some problems with this unit, but some had remained unresolved; and now, in any case, I was starting over.
I had downloaded and installed DiskStation Manager (DSM) 3.0, the Synology Assistant, and the User's Guide. DSM was a web-based program, apparently running on the DS109, that I accessed by simply typing the DS109's address (e.g., 192.168.2.1) into the Firefox address bar. I was able to connect to the DS109 by typing the username and password that it needed (i.e., not my Ubuntu username and password).
As outlined in a previous post, I had also created a mount point ("sudo mkdir /media/SYNDATA") for the DS109's SYNDATA partition. The fstab (i.e., "sudo gedit /etc/fstab") contained a line that had worked previously to let me contact that partition. The line I was using was this:
//192.168.2.1/SYNDATA /media/SYNDATA cifs user,uid=ray,gid=users,rw,suid,credentials=/etc/cifspwd,iocharset=utf8 0 0where "ray" was my Ubuntu user ID, not my DS109 user ID. The DS109 user ID was contained in the /etc/cifspwd file; and now, as I looked at this, I realized that reinstalling Ubuntu from scratch had surely wiped out that file. So I recreated it ("sudo gedit /etc/cifspwd"), using my DS109 user ID and password, in this form:
username=[DS109 username]and that's all that file contained. Example: if my DS109 username had been Joe, the first line in this two-line file would have been "username=Joe," and the second line would have been "password=JoesPassword" (wahtever that user's actual password was). Then I typed these commands
sudo chmod 0600 /etc/cifspwdThese were the basic steps recommended in a relevant page in Synology's wiki. The problem -- or at least *a* problem -- as I eventually figured out (or re-figured; Synology's tech support may have originally suggested it), was that the "credentials" part of the fstab line was not working. If I replaced "credentials=/etc/cifspwd" with "username=Joe,password=JoesPassword" (and then saved fstab), then the "sudo mount -a" command worked: SYNDATA appeared in Nautilus like any other partition. So what would happen if I put exactly that -- username=Joe,password=JoesPassword -- on the same line in /etc/cifspwd, instead of putting them on two separate lines? No dice. The cifspwd file was a dud. I left the username and password information in the fstab, and deleted the cifspwd file ("sudo rm cifspwd").
sudo mount -a
So the short answer I arrived at, here, was that the Synology wiki was wrong, at least for my purposes. I needed to take all the other steps -- creating a mount point, etc. -- but instead of creating the cifspwd file, I just needed to enter a line in /etc/fstab of this form:
//192.168.2.1/SYNDATA /media/SYNDATA cifs user,uid=[Ubuntu username],gid=users,rw,suid,username=[Synology username],password=[Synology password],iocharset=utf8 0 0and possibly the "iocharset" part was optional.
