General :: Centos Grant Read Access For RSync
May 2, 2011
I am trying to setup a Rsync backup method.I have multiple files and folders all OWNED by different users.Now I can read the files as root.But I want to make a user for RSYNC that can ONLY read all these files for copying them across.It requires to create a non password login and I dont want to do that with the root user ! I have tried to create a new user and use 'setfacl':setfacl -m u:someuser:r /var/test.But when I su to 'someuser' I cannot copy the files to my homedir. So I think it wont work for rsync also.

On RedHat 5 64-bit.I have a group that requires read-only access to the /var directory.I believe someone mentioned SGID and ACL stuff, and I've been researching this solution, but I wanted to check with you all first to ensure there wasn't an easier way to do this. Basically, I just need folks that belong in this certain group to read the contains of any file/directory contained within /var.

I am trying to set up an ampache server using apache as the webserver. The instructions have the following line as one of the requirments: Your webserver has read access to the /sql/ampache.sql file and the /config/ampache.cfg.php.dist file..I have essentially zero experience with apache, and I'm not sure how to grant read access to a file.

I am running version 5.5. I am using Grsync to back up 2 folders to an USB external 1.5 terabyte drive. Sometimes grsync backs the folders up correctly but most of the time, I need to unmount and then mount the drive to get it to work.

I regularly rsync directories to an external usb drive. Recently I've started getting errors which look:
blah blah:Read-only file system (30)
The external usb drive has two partitions (ext3 and fat32) and I rsync to the ext3 one. The rsync command is
rsync -ahi --delete /home/mike/some_dir /media/usb_drive
People have reported this error with faulty usb cables but everything was working fine until recently so it seem unlikely a usb cable would suddenly wear off.

I'm using Kubuntu 10.04 at the moment. Every time I log in, KDE Wallet asks me to give a password so that Kopete can access my login password to login. Is there any way you can 'grant permission' to access the wallet for certain applications so that I don't have to fill in my password every time?

I have wicd 1.6.1 (bzr-r426) and it is working very good with my root user but with all those which have not the root rights wicd asks for superuser password to connect. I want to avoid this pop-up window to be shown, how can I proceed? I first thought about the sid and gid but it seems that there is no improvements using chmod 4755 and 2755 on the different files involved in.

I have a JavaCL program trying to open a port on 41xxx and it is getting permission denied unless I run it as root. I would like to grant a single user this permission for opening this port. This program runs fine on a vanilla ubuntu install but not on server. Where does Ubuntu handle user permissions for opening ports?I understand this is typically a no-no on a server but this is an unusual circumstance.

We are aware that unix has three sets of permission such as owner, group and others. I have a requirement to have a read-only access to a folder and sub-folders and the group that currently holds can't be used. Because it has write privileges. I would rather not prefer to use others, because it opens to each user in the system.have read-only access for another group?

I'm using Arch right now and i'm having problems syncing my ipod with Amarok (KDE). Everytime I would want to sync a song, it would give me access denied. it is currently mounted at /tmp/ipodbxQtrU and i have tried using chmod with no luck. I was in root when i used "chmod -R user ipodbxQtrU" and it said operation not permitted.

What is going on here? I can't access /etc/sshd_config to read or edit it, even as root. (Using debian-live 6.01)
root@debian:/etc# ls -l /etc/ssh*
total 132
-rw-r--r-- 1 root root 125749 2010-02-28 01:37 moduli
-rw-r--r-- 1 root root 1616 2010-02-28 01:37 ssh_config
-rw-r--r-- 1 root root 2453 2010-03-13 17:32 sshd_config
[Code]...
I also checked the permissions for the parent file /etc, and root has rwx. Is this something peculiar to the overlay file system used in debian-live, or just another unix gotcha?

I need to create a user with least permission on the production server. He should only be able to read or execute the files that to be specific. For example: I just need to give him a set of commands to run.Besides those command execution He should be prevented to run any other command and He should not able to create any files(write permission).
How would i proceed about this.

I've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.

I have two servers, both running CentOS, but one running Cpanel as the control panel and the other running Webmin.
I would like to sync the web folders using rsync. However, when I sync the files from the Cpanel host the permissions look as follows:
Code:
But that doesn't work on the Webmin server which needs the following:
Code:
It seems the Cpanel install has the group as 'nobody' whilst webmin has it the same as the file owner. I can fix this by running:
Code:
But as the file transfers will be frequent, I don't want the files to be inaccessible until chown is run.
So, what I really want to know is - how can I change things on the 'webmin' server so that files with ownership owner:nobody will run?

I am looking for a secure way to backup data from user's computers ( Linux/Windows ).My needs :
1. Secure

3. Windows/Linux compatible ( server will be Linux only )
4. Incremental backups
My preferences :
1. Rsync
Things I can not do :
1. Give out shell access ( forget rsync -e ssh )
2. Use a protocol that takes too many ports ( my box is behind my router ).

What I'm trying to do is to grant my regular user to locally mount partitions and shutdown the machine without a password. Here is what I've done to /etc/sudoers:
Code:
Host_Alias LOCAL = localhost
Cmnd_Alias SHUTDOWN = /sbin/shutdown
Cmnd_Alias MOUNT = /bin/mount, /bin/umount
<my_username> LOCAL=(root) NOPASSWD: SHUTDOWN, MOUNT
%wheel ALL=(ALL) ALL
My user is a member of wheel group and I want to type the password for each sudo command except for shutdown and mount. However I am asked for a password whenever I execute "sudo mount [...]" or "sudo shutdown [...]".

I installed CentOS 5.4 on a virtual server to host the tool OpenVAS, which is used to execute vulnerability assessment.This tool is based on a master engine and thousand of plugins, each one doing a specific, little function.I wrote a cron that, every sunday, updates the list of these plugins to keep the system updated; this cron uses a tool's proprietary function that download the new plugins from a site using rsync.I was using the rsync 2.6.8-3.1 until last week, when I decided to install ALL the updates proposed by operating system itself (more than 170) and the whole list includes rsync 3.0.7-1.el5.rf (from rpmforge).
This monday, the log of the tool's function gave me a bad response about the impossibility to establish a connection with the remote server due to a connection timeout.Before doing the rollback of the system, I tried to understand what happened, so I started manually the function on a terminal and, together, I was watching the results using netstat -tuvnap, so I saw that there was an attempt of connection, between my server and the remote one, but the connection did not finish the three way handshake, because the state of connection was always "SYN_STAT".I tried to value the $RSYNC_PROXY variable, because there is a proxy between my server and the world, but the result was exactly the same, so I was forced to execute the rollback of the system, which works very well now!

I'm making my own yum repository - firstly so that all the machines I administer can be updatedvia the internal network, secondly so that I can test any updates on a spare machine before passing them on, and thirdly so that I can add my own repo for internal software.
I've created the necessary folders under my webserver, and used rsync to update them from my local CentOS mirror, following the instructions at [URL]
I notice it says to run "createrepo" on the base repository, created by copying the rpms from release DVD.
When I rsynced the updates repo, but I notice that the files in repodata are very small. In fact, having a look inside them, filelists.xml contains no file details. But if I run createrepo in the updates directory, filelists.xml gets lots of file details inside it.
I wondered if maybe the local mirror hadn't been updated properly, but checking against mirror.centos.org shows that has the same files.
how does the (real, live, CentOS) updates repo work when there is nothing in the filelists?

I have a script that users execute to copy files from one server to another 3 boxes.
I want to prevent rsync from trying to copy files with spaces.
Anyone have an example I can use?
The rsync just craps out when they try to sync files with spaces, I tell them that but....

I believe it was rsync was the tool. I have a box running CentOS 5. It has a 250GB HD in it. I have another drive with the exact model. Currently it has a as a said a 250GB IDE drive. I want to shutdown the machine, install this other hard drive and set up a cron job that will backup my main drive at times that I set. This way if the main drive fails, I do not loose all the data and have to rebuild the server from scratch as I have been custom configuring it for years. I can't remember if there was an issue with the main drive being mounted to back it up or not. I have looked at some of the how's on rsync but they seem to only talk about using another server for this. If I shit down the box, install the new drive, and the box boots back up, is it going to ask about that drive or what do I need to do to get rsync going and does it partition the drive as such? And can I do it this way. This way if the main drive fails, I can just swap the drive and be on my marry way.
