Permission denied on USB HDD using WinSCP

samalchow · 02-02-2014, 07:32 PM

I've had a USB HDD hooked up to my Debian distro for some time. Currently I have been using the sharing the drive using samba. I've just tried to use WinSCP to transfer some files to this drive but I've been getting a "permission denied" from the application. Currently its set to nobody:nogroup. What is causing this?

is if physically connected to the Debian box? if so what is the output of

Code:

df -Th

also what path are you using to try to get access via WinSCP and what user/pw did you log into the Debian system with?

Yes its physically connected. It's the last line.

well its mounted, now as root run the following, also please use code flags it really makes life much simpler to read the copy/paste you put on the screen thank you.

Code:

ls -laF /media/ExtraNas

they should look something like this:

Code:

[user@centos ~]$ df -Th

total 36
drwxr-xr-x. 4 user  user    4096 Aug  6 16:03 ./
drwxr-xr-x. 5 root root   4096 Aug  2  2013 ../
-rw-r--r--. 1 user  games  6148 Jan 19 23:50 .DS_Store

drwxrwxr-x. 8 user  user    4096 Aug 28 06:43 public/

Note that one of the hidden files (.DS_Store) is a different group then the directories. thats ok. it tells you something about the UID/GUID of the user who created the file. FYI its created by my FileZilla client even though it uses the same user user UID/GUID as my normal user. due to FileZilla there are some issues with some files. its easy to fix and to be blunt does not affect access from my normal user via any other means of access.

now the reason I want you to post the ls -laF (those are lower case L's btw) is so you can look at the user and group ownership of your mount point.

/media/foo is typically created automagically via the GUI so the permissions should be correct. As it is a Linux formatted partition you should also be ok. worst case you go in as root and fix things

.

This is what I got.

Code:

ls -laF /media/ExtraNas/

With the "BackupofaBackup" directory what I was trying to upload files to

lleb · 02-03-2014, 07:08 PM

simple, look at the permissions on that directory...

Quote:

drwxr-xr-x

it clearly states the owner, in this case nobody (not a good thing), has full read, write, execute permissions, but group and other only have read and execute.

what is the output of

Code:

 $ whoami

run as your normal user?

samalchow · 02-03-2014, 09:51 PM

Output is "smalchow", my default user.

If nobody is the group, wouldn't anybody be able to write to it? Belive that was the original thought process

lleb · 02-05-2014, 08:25 PM

your user would have to be in the nobody group.
