Hello everyone!
I have the transmission bittorrent client daemon set up at my ubuntu server, and I'm having some problems with my permissions. Namely, transmission can't seem accept new torrents, it pauses download and says 'permission denied'.
The download directory is on my sdb, mounted as sudo, with group plugdev.
Several people have ssh access to this server, so I did a chmod 770 to the mount point, since I don't want people accessing that disk (I belong to the plugdev group).

Now, when I do a ps aux, the following is returned:
1000 4638 2.0 0.7 69744 15336 ? Sl Mar28 148:06 /usr/bin/transmission-daemon -f

I was under the impression 1000 is the current user. Is this not so?
If it is, how come the daemon is being denied access to the directory?

*edit*
it's a ntfs filesystem, in case that helps

Well some distros will mount ntfs partitions read-only, by default. Check the output of "mount" to see if your partition is writable. Also, you're going to have problems settings linux-style permissions on an NTFS partition. You'll have to change the uid, gid, and umask options in /etc/fstab in order for linux to treat the whole filesystem as belonging to that user ("man mount", and look for "Mount options for ntfs"). Changing the permissions on the mount point itself won't really help with that.

As for the output of "ps", 1000 is the UID of the user running transmission, probably your account. It's not necessarily the current user. Normally, though, "ps" will give you the username, instead of user ID. Have you made changes to /etc/passwd or reconfigured users recently?

Thanks for your help!
I've managed to mount the partition as the current user, but strangely that didn't seem to help at all.
I was messing with it the other day and noticed that the torrents path had somehow reverted to "/" - so, of course it didn't have permissions to write there! It seems to do that every time I restart the daemon; I guess it doesn't save the config file properly.
As to the uid 1000, the 3 ubuntu systems i have list all my account's processes as that, and none show the user name. I'm not really concerned about that, though, all seems to be working fine.
Again, thanks.
