Security :: Why Rsync Updated Password Files

Mar 26, 2011

I synchronise my data disk to a backup disk daily. Yesterday I noticed that rsync listed in its output my password-managers directory, which contains an old Keepass database and other Windows password programs I used long ago. I haven't accessed this directory in ages, so I was wondering why rsync felt the need to list itthe directories it updated.Modification dates and last accessed dates are what I would expect; nothing recen

Software :: Run Rsync To Download Files From A Server Without Rsync Daemon?

Sep 18, 2009

I just tried to sync files from one server to another. After the sync process, I found the files are bigger than original ones.

I looked up the web and found someone mentions the rsync daemon. So I have to run the daemon on one server before I run the rsync?

The command I used is rsync --partial --progress -r source destination

Ubuntu Security :: Accessing Password Protected Ext3 Files?

Jul 31, 2010

I have a drive that originally was used with a Linksys Network Storage Link (NSLU2), then stopped working with it. Now I'm trying to get the files off the drive. When I USB connect the drive to Ubuntu, I can see the files, but I'm unable to open them or copy them. The error message is: "Error Opening File: Permission Denied". I did have permissions set on the NSLU2. So far I'm not able to find a way to get around the permissions issue in Ubuntu.

I have used apps like EASEUS Data Recovery and Recover My Files. It appears that they are finding the files and are able to access them, so I know it can be done. I don't mind spending some $, but these apps are taking a *long* time to run. If I could properly access the files in Ubuntu long enough to copy the files, I think I'd be all set.

General :: Rsync - Password-file Not Working ?

May 23, 2011

I made a shell backup script that uses Rsync and I am trying to get rid of the password prompt because it will use a CRON to run. I have set my variable in my shell script at:


And the password in that file only takes up 1 line.

However when I run (ignore $DESTINATION)

rsync -aRvz tmp $DESTINATION --password-file=$PASSWORD_FILE

It still gives me the prompt. How can I accomplish this? I cannot allow a prompt and I do not want to have to use keys.

Networking :: Automatically Pass A Password To Rsync For Remote Host?

May 24, 2011

I need to be able to use an rsync command in script that will be run by cron. And it needs to be able to pass a password to rsync so that the remote server it's connecting to will authenticate.

I cannot set up ssh keys between the two servers, it's not an option. I cannot use any other language other than bash, it's my only option. I know this is highly insecure, I have no other option.

So far I have this:
rsync --rsh="/usr/bin/ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o PreferredAuthentications=password" -raxv /source/dir/* user@remotehost:/target/directory/.

This allows the script to ignore host verification and goes directly to the password prompt. I need the script to fill in this password prompt with the password that is stored in a variable.

I tried using expect, but I honestly don't know the syntax, it just keeps failing. A lot of the examples I'm finding online for expect starts off with a "spawn", which i don't have installed, and not sure if I have the ability to install it yet.

Security :: Backup Securely With Rsync?

Jul 11, 2010

To copy from production to standby over the internet I use a cron job doing rsync -avze 'ssh -p 8022' --exclude-from= ....

My question is: should the cron job run on the production or the standby system. Root access to the remote system is given by a pass phrase-less ssh key. Currently I run rsync on the production system. I guess that it is more secure because the standby needs no ssh login to production. Running rsync on the standby would use less resources on production. I am concerned that in this case there would be pass phrase-less access from standby to production.

Security :: Securing Backups Via Rsync And SSL?

Apr 27, 2011

There are multiple servers to be backed up. Different access rights exist in each server. There are two backup servers with plenty of disk space, one local, and one offsite. The local one feeds to the offsite one. The rsync command is being used to make a replica of backed up data. Deleted data is also being archived. There are two methods that have been considered: One is to have the individual servers run rsync which logs in to the backup server to push data. Two is to have the backup server run rsync which logs in to each individual server to pull data. Because system data is involved and meta information (like owning user) must be stored, root is required to access the data as well as to store it. That means everything runs as root both ends. So method one was quickly dismissed because each server would effectively have rights to access ALL the data on the backup server since it logs into the backup server as root. The security containment here involves different groups using different servers, and they need to be isolated from each other.

But even method two involves some risks that are a concern. This means one machine has access rights to every server. If the backup server were compromised, every machine could be compromised.What I'd like to find is some way to allow backups to be run without either machine granting root access to the other, while still running as root, or something equivalent, that allows accessing all data and storing all metadata. So I was looking at setting up an rsync daemon on each individual server (running as root so it can access what it is specified to access), and running an rsync client on the backup server (as root so it can store metadata). This opens network access issues. Any user on the network can connect to the rsync daemon. So password protection is needed. But this communication is also not encrypted, which exposes the password and the data should the network be sniffed.

So now I'm thinking about a non-root ssh login between machines. The backup server would login to a non-privileged user on each individual server and set up a secure forwarding channel to the rsync daemon. Is this the best that can be done? Is there a way to run rsync via SSL with key verification so it can all be done together? I'd like to have the rsync daemons configured to always talk SSL, and always verify the client's key against a list of authorized keys, and likewise the client verify the server's key against the known public key for that server.

Ubuntu Security :: Generate Password / Encryption Keys For Password

I know this has probably been asked too many times here but I need to secure my emails. Personal matters of course. But yeah. I use the program "Password and Encryption Keys" to generate a key to sign my emails with but I do not know what to do. To be blunt, I'm stupid when it comes to this. IF not, steps in creating a key? and giving it (my public key) to the significant other? Finding where both keys are? Implementing it into Thunderbird? If it helps any here's some extra information: Ubuntu distro: Ubuntu 10.04 Email client: Thunderbird

Ubuntu Installation :: Keeping Software Updated For Security Reasons?

Jan 7, 2010

I've recently built a VM appliance using Ubuntu 8.04 that is given to customers for an easy deployment of our software. Ubuntu works great in a VM and its perfect for our software (which is a web application).

Some customers are paranoid (rightfully so) and they will run a vulnerability assessment on the web application. A particular customers' assessment fails as it finds that the appliance isn't running the latest version the Apache web server. I thought that just running "apt-get upgrade" would upgrade all of the software packages to the latest so that failures in the assessment caused by outdated software packages would be resolved... However this is not the case...

I realize that there is a probably a whole process for submitting/approving the latest versions of software packages in Ubuntu, that then get pushed to the repositories - But how does this work? What exactly does "apt-get upgrade" do if it doesnt upgrade packages to the latest?

For example: I need Apache 2.2.11 to fix a particular vulnerability. But when running apt-get upgrade, it doesnt actually upgrade the Apache version number (or any of the other packages). I'm stuck on Apache 2.2.8, and I can't find a .DEB installer for 2.2.11 or later.

Security :: Run Intrusion Detection System On Regularly Updated Desktop?

Apr 1, 2010

My desktop (the system AIDE runs on) is reguarly updated, and the file output can become enormous, making it hard, if not impossible, to track down out of place files. I have recently thought of uninstalling it since I can't tell what is out of place and what isn't, but before I do that I wanted to ask everyones opinion regarding what would be the best way to handle such a program on a desktop that has some core files changed reguarly. This sytem is running Gentoo, so updates affect a number of directories.

Security :: Logging In As Root Over Rsync/ssh For Backups?

Sep 30, 2010

I need to login as root, or at least get root privileges, in a cron triggered backup run. The straight way to do this would be the backup server making an ssh connection to the server to be backed up (this way because I want to avoid many servers being backed up in parallel and the backup server itself would be managing this diversity), via the rsync command which would be performing the backup's synchronization step.

I'm looking for alternatives to this in some form. I'd like to disallow direct root login to my ssh port (not 22One idea I have is to have the backup server initiate an ssh login as a non-root user, to either the actual source server, or to a server that can reach the source server ... and set up port forwarding. Over the forwarded port, then initiate the rsync that logs in as root via another port that allows direct root, but cannot be reached from the internet at all (because the border firewall doesn't include this port as allowed in).FYI, these logins will be using ssh keys, not passwords. I do need to keep ownership metadata for files being backed up, so this is why I am using root. Also, rsync is needed to get the incremental updates to keep bandwidth usage lower (otherwise I could just transfer a tarball each day).Anyone have any other ideas or comments, for security issues, based on experience doing things like this (backups, routine data replication, etc)?

Ubuntu Security :: Changing Password Seem To Be Potential Security Hazard?

Aug 3, 2010

I already posted a topic similar to this concerning the Desktop OS version, but this deals with the Netbook because unlike the Desktop, the Netbook is less cooperative. Allow me to elaborate: Today (or rather yesterday since it's not after midnight where I am), I changed my password because I was hopelessly confounded about how to get my Wireless Network card up and running after it had been installed and I was allowing my dad to use it. This issue has since been resolved, however...

When I chose my password during the original installation, there was no mention of it being "too simple." This is where the Desktop OS and the Netbook OS differ. The desktop will let me change it in the terminal without any errors. The Netbook will not. When I've attempted to revert it back to the original, it will not let me do so in the User Profile or in the Terminal. The Passwords and Encryption Keys application also does not appear to help.

So now even after I've changed it to a different "complicated" password I am still prompted to insert two different passwords since I changed my user password but I am unable to change the password I input during the installation. A bit screwy methinks. This is extremely important. I'd like to know how to change the original installation password.

If I can't change the main password on my laptop then this is a serious potential security breach just waiting to happen (especially since it's on a laptop and I will be hauling it around with me) and I will most likely install a different OS if this isn't resolved --- It would be very unfortunate since I spent the whole day fixing it and I really enjoy the interface. Luckily I can live with this on my Desktop since I'm not going to be hauling it around with me everywhere when the school year starts.

Ubuntu Security :: Rsync Automated Backups Of Entire File Structure Over Ssh?

May 16, 2011

I am in the process of writing an rsync script to run unattended backups of my entire file system to another system located on my local network using ssh and password-less rsa keys.

I will absolutely will not use password-less keys with the root account and this is the limitation preventing me from accomplishing my goal because root is required by rsync to access the / tree and copy it to another location. I decided that if I compiled the script into a binary that I didn't have a problem with the password being contained within the binary itself but from what I've read there is no way to elevate to root and then back down to user level from within the script/binary.

I can create the script as the user and use chroot to make it owned by root but retain execution permission for the user but it will still cause the ssh login to be under root and therefore require either that I am there to enter my password or the use of password-less keys under the root account which I reiterate I will NOT do. Currently the script is executed by the user on the machine containing the files to be backed up.

Ubuntu Security :: Back Up All Systems To An External Hard-drive Using Rsync

May 20, 2011

I have an OpenBSD and a FreeBSD system and a mac. I also have a Ubuntu server. What i would like to do is back up all these systems to an external hard-drive using rsync when the external usb disk is connected to my Ubuntu box.If i format the external usb disk with cfdisk and the create a non-bootable ext3 file system on this external disk and create and put all the necessary public keys on the Linux box then from the BSD's or the mac issue the command:

Code: #rsync --progress -avhe ssh --delete / user@ubuntuBox:/usb/disk/path/dir/ Will this back up the entire systems so that they can be restored in the event of an emergency? I should store each OS just in a separate disk file of the external usb drive each time right?? Because i would rather not have to format the external usb drive for each different OS. Would this work? and would the restoration command for these BSD's be:

rsync -avze ssh UbuntuBox:/usb/disk/path / I just need to know the basics. I'm sure given that i'll be able to automate the process. I don't want to clone the disks for forensics. I just want to have a way of restoring to a clean OS. This is the most basic question:All the howto's never mention whether or not you have to have an rsync server running on the machine your backing up to. So do you just push or pull from one end of the connection only or do you have to have a client at one end and a server at the other, as is traditional?

Fedora :: Rsync Not Copying All Files?

Sep 9, 2011

My Source folder contains 424.8 GB in 502,474 files. My Destination folder was created fresh, and after the copy contains 394.0 GB in 486.514 files. I am running it as grsync with root authority. The only options are to preserve time, permissions, owner and group., and to produce a verose output and transfer progress. There are no exceptions specified to skip any files.

The rsync command is this:

rsync -r -t -p -o -g -v --progress -c -l -H -D -s /mnt/Backups/monthly.3/ /mnt/EX-Fantom/monthly.3/

I have run it again to give it a chance to get it right. Same result. The source is in an rsnapshot folder, but this is the first backup, the original, containing only whole files, not links.

General :: Rsync Would Keep Sending The Files Over And Over Again?

Mar 2, 2010

I'm trying to using rsync to backup some files, about half a TB. It's now it a state where it keeps sending the same files everytime it runs. for example:

rsync -av /data/source/* user@host:/data/dest
sending incremental file list

I then verify those files are copied over. then the next time it runs it does the same thing

rsync -av /data/source/* user@host:/data/dest
sending incremental file list

any idea why it's getting stuck on these files? I've tried to wipe the whole dest directory out and start over but no luck.

Ubuntu :: Rsync Wants To Recopy All My Files On Next Run / Why Is So?

Mar 15, 2010

So I just used rsync to backup about 400gb of data to my NAS. Look just over a day to complete, which is what I figured. I decided I should run rsync again to see how its going to handle comparing and only adding new files to the remote location. So I added a few new files and then ran the backup again. Well rsync is trying to do a complete copy of all of my original data, even though they have not changed.

Is there a way that I can tell rsync to compare the two directories and only add the new files and delete the ones that are no longer in the original location?

Here is command that I am running:

sudo rsync -azvv --progress --stats /media/sda1/multimedia/movies /home/codeblue/NAS_Share_Point
