I repartitioned my installation in VirtualBox (from a single / to a /, swap, tmp, var, home and usr). As i ran out of space i mounted a host-folder (with sshfs) and copied some stuff over there (for sure var and home). I ran into messages saying: "can not preserve ownership"
View 8 Repliesi have written one backup script in linux workstation.The backup script will do zipping files and moved to the backup directory(i,e /net/ts-bcn/sb_backup/sand). while moving zipped files to the backup directory i am getting some error like this #error:mv:failed to preserve ownership /net/ts-bcn/sb_backup/sand operation not permitted. i am getting the file owner and group owner as nfsnobody for the zipped files.
View 1 Replies View RelatedI would like to create an encrypted folder which can be shared by users included in the users group.To do so I used encfs:
Code:
cd somewhere
sudo mkdir encrypted visible
sudo chown root:users encrypted visible
sudo chmod 770 encrypted visible
encfs /somewhere/encrypted /somewhere/visible -o allow_other -o umask='007' -o uid='0'
Now if a user (included in users) creates a new document in the visible folder, that will be
Quote:
-rwxrwx--- 1 root users 0 2010-03-02 14:19 new file
While I would like it to be
Quote:
-rwxrwx--- 1 user users 0 2010-03-02 14:19 new file
Mounting encfs without the option uid='0' gives same results with only difference that instead of root the owner is the user who mounted encfs. Also copying a file owned by different user rather than root goes to the same: for example having in my home a file like
Quote:
-rwxr-x--- 1 me users 0 2010-03-02 14:30 myfile
and trying to copy it to the encrypted shared folder with
Code:
sudo cp -a -v ~/myfile /somewhere/visible
will give something like
Quote:
cp: failed to preserve ownership for `~/myfile': Operation not permitted
And the copied file on the shared encrypted folder will be as usual:
Quote:
-rwxrwx--- 1 root users 0 2010-03-02 14:30 myfile
Is there a way to mount encfs in order to preserve ownership?
I need to make an ISO9660 file from a directory, but some of the files have names that are logner than 37 characters. I could not find a way to get the long names preserved.

View 5 Replies View RelatedI have been tooling around with different way of getting our local Debian network mirror back up and running with different various scripts. I have tried apt-mirror which was a breeze to setup and run, anonftpsync again super easy to get rolling.
My question is there a way to make sure our Sarge distro doesn't get deleted from the mirror? A filtering command for rsync possibly?
I started to go over the script for the ftpsync (debian recommended!) and to be honest it seems way over my head due to lack of documentation that I have been able to find.
How does Debian preserve/merge config file information during software upgrades? My google searches left me a little unclear on this point. Also (if you happen to know) does Ubuntu use the same method?
View 2 Replies View RelatedI've recently started setting up a new wordpress install on a new dedicated server. The system is installed on a linux debian 5 setup and running on apache.Having only ever run shared hosting before this setup is a much bigger leap than expected, but after a couple of weeks doing bits here and there I've finally got the setup running, and all appears ok.My issue is as follows:On the server the default owner of all the installed folders is "root"In order to allow media uploads, plugin installs and upgrades and wordpress auto-upgrades I've had to Chown the owner of the entire wordpress directory to the server as follows:Chown -R www-data:www-data /usr/share/wordpress/
Can anyone tell me if this is actually secure? (clearly if the server is compromised the folder would be writeable!) If not would I be better changing the owner back to root (or even creating a new user for the wordpress folder?), then chown just the uploads, theme, and blogs.dir folders to allow media uploads, upgrades, etc from with the wordpress, and then only chown the entire wordpress install when upgrading or installing new plugins, themes, etc.?Just a bit lost when it comes to the ownership of these folders as changing these ownerships is the only way i can get the system functioning 'correctly'
Being new to Linux, i've just about got used to the Debian setup procedure now, but had a quick question on the default ownership of files and folders. On my default Debian installation, almost all the folders and files are owned by root:root. Is this the correct advised configuration or should the folders and files be owned by a user without root permissions - eg user:user?
View 12 Replies View RelatedI know rsync generates a lot of questions, but I have not found an answer to this one about whether the archive option (rsync -a) ever misbehaves. I am transferring data from field instruments running Debian etch to a central server running Debian lenny. My command is below:
Code:
rsync -av --remove-source-files --log-file=rsync_20110612_0656Z.log ./20100616/ archive@bigserver:/mnt/ZAP_DATA/20100616/zap2/
After rsync runs, the directories it touches on bigserver have very strange permissions
as follows:
Code:
d-wxrw--wt 2 root root 4.0K 2010-10-26 04:31 20101026
This says that directory 20100226 can be written by anybody, but can't even be read by its owner! I thought rsync was messing things up, but in the process of writing this question I discovered that the original files that I am trying to sync have these crazy permissions. So I no longer have a question, but if future LQers think that rsync -a is messing up their permissions, this post may confirm that it is merely copying their messed up permissions from somewhere else, as it is supposed to do!

View 8 Replies View RelatedI have a python script on one server (serv_one) and I am trying to execute it remotely from another (serv_two). The python script takes an argument with spaces. If I execute it locally:
Code:
foo@serv_one> script.py --o "arg one"
"arg one" is preserved, of course. ( argv = [ '--o', 'arg one' ] )
However, when I execute it remotely:
Code:
foo@serv_two> ssh ... foo@serv_one script.py --o "arg one"
the double quotes around "arg one" are dismissed ( argv = [ '--o', 'arg', 'one' ]. I've tried many combinations of single quotes/double quotes/backslashes, etc, to no avail. One hack solution I came up with, since I have the flexibility, was to replace all spaces in the quoted argument with a character that would be invalid in the argument (before the ssh call), and replace those with spaces in script.py. I would probably like to avoid this solution if at all possible.
I've got a Gentoo box that I'm interested in switching over to an Ubuntu box.
I currently have the partitions laid out using a mixture of RAID (mdadm) and LVM2, as specified in this document [1].
Ideally I'd like to just wipe out the non /home partition, as it's got data I'd like to keep.
Is it possible to reuse the current setup, or do I need to restart? vgdisplay, vgchange -a y, etc don't yield any results from the Ubuntu LiveCD, and I'm wary to run any commands that might wipe my data.

I have an rsnapshot backup that I need to move off of a corrupt Linux file system. I need to preserve the internal hardlinks. I've tried rsync -H and using a newer rsync and neither preserve the hardlinks on OS X.
I tried to get rsync -H working and I've isolated it to the file system mounted. I can preserve hard links copying locally (HFS to HFS) but it doesn't preserve when I try to rsync off of a SMB file system mount or AFP file system mount. Is there some mount option solution to getting OS X rsync to obey -H?
I recently installed Kubuntu 9.04 + Nvidia driver 180.44 on my Dell Latitude E6400 (1440x900) with NVIDIA Quadro NVS 160M. I have the G2410 1920x1080 external monitor. The monitor is connected via VGA. I am very pleased to have the monitor running at full resolution. However, the settings don't stay intact after rebooting.
If I have the monitor connected and turn on the the laptop, only the laptop screen is active. Then, I press Fn + F8 twice to switch to the external monitor which is always reset to 1440x900. After logging in I open Nvidia settings and switch the external monitor resolution to auto. There is a warning about Meta modes and I do auto fix. Then compositing is disabled, so I open system settings, turn off then turn back on desktop effect. Also, if I want to switch back to the laptop display, it stays stuck at 1920x1080 on the laptop.
Is there any way to set this up so it is automatically detected when the external monitor is plugged in and runs at the correct resolution? With my old M1330 and Intel X3100 graphics card, it would do this and was very convenient switching back and forth between the laptop display and external monitor.

A friend backed up an in accessible Windows 7 partition to a big (close to 1TB) external USB drive using KNOPIX. Unfortunately the umlauts and accents in the file names of his extensive music collection now appear garbled (UTF8 vs ISO xxx, I guess) when he accesses that drive from Windows. My guess is he needs to mount the two drives in a 'special way,' that takes the diacritics translation into account, on KNOPIX? Or do you have another idea what went wrong? This is the second part of a windows/linux problem I'm having. See how-does-one-mount-a-partition-in-windows-7 for the other part

encfs: preserve timestamps on a shared encrypted folder?
I will be version-upgrading a friends (Ubuntu only) laptop very soon. It is 9.04 now and the new version will be (ideally) 10.04.1 The machine has a large unused area on the hard drive and who has known this situation was to use the uncommitted area to do a complete new install of 10.04.1, leaving the 9.04 unchanged (useful insurance). Then, copy, paste (?) the /home directory from the 9.04 into the newly completed installed 10.04.1 overwriting the installed directory.
Opinions seem to support the notion that such a paste into 10.04.1 is likely to be successful and trouble free as long as the 10.04.1 installing username is the same as the 9.04 username with same privilege level. I would be grateful for comments here, particularly with any details, gotchas, you can see.

I need to update tracker on my system but this will erase the metatag database I've been building up over the course of months for the purpose of indexing a news archive. So the solution seems to be, 1) save the output of tracker-tag to a text file for all relevant files within a directory, 2) upgrade tracker (since the version in the Ubuntu repositories is very much out of date) and then 3) use a script to parse the text file and pass appropriate arguments back to tracker-tag to rebuild the database. It sounds as though it ought to be simple enough, but I need a push in the right direction, which hopefully will not be off the cliff. Before I confuse my metaphors any further, here's what the text file looks like.

I have my hard drive arranged with a single large ntfs data partition and a number of smaller partitions for /home etc. Here's the line in fstab:

But the ownership for that directory is root and I can't change it for some reason, using this line:
Code:
sudo chown -R shmuck /home/shmuck/data
It just doesn't do anything.
