Updating Rsync to version 3.0.4


Even though my job title is "Web Developer" at the organization I work for, I have also become one of the server administrators / office techies / and handy man.

I am working on a backup solution for downloading our website files (from a remote datacenter) onto an external hard drive in our local office, and am trying to update rsync. I have shell root access.

When I issue
Code:
rsync --version
I get
Quote:
rsync version 2.6.8 protocol version 29
amongst all the other information. Obviously this is an old version of rsync. According to rsync's website, the current version is 3.0.6. Unfortunately, I have a Windows computer as my office work station, but at least I've been able to install cygwin. Rsync version 3.0.4 is installed on cygwin.

So, on the RedHat server, I tried running:
Code:
yum update rsync
and this is what I get:
Quote:
root@servername: yum update rsync
Loaded plugins: dellsysidplugin, rhnplugin, security
Excluding Packages in global exclude list
Finished
Skipping security plugin, no data
Setting up Update Process
No Packages marked for Update
I emailed the datacenter, who is supposed to be keeping our system up to date, and they responded with the following:

Quote:
I've looked over the server and it appears the installed version of rsync is the latest available from Redhat, and as such there is nothing we can really do to update it in a supported manner.
So why hasn't Redhat updated rsync in their repositories? Or is there something else that I'm missing? Any ideas?

Hi.

RedHat's quite a conservative distro - they don't generally use upstream software at the latest version.

Any particular reason you want to update?

Hey Dave,
This makes sense. I don't really have a reason to update except for possible security updates. I looked over the status of our server yesterday and found quite a few outdated packages when I ran
Code:
yum list updates --security
. Those have since been taken care of, but I was just confused as to why the latest version of rsync wasn't being provided by the RedHat repositories.

After I reviewed rsync's website, it looks like this could even be a security issue in some customized cases. Fortunately, we do not fall into this category and so I don't think that updating rsync from version 2.6.8 would address any security concerns.

So basically, I'm using rsync and I wanted to make sure I had the latest, most stable, most secure version before I really got underway in my project.

Usually latest is diametrically opposed to stable and most secure. Software versions have to be around a while to find the bugs in it(stable) and they need real world exposure to check for security.

Be aware that many packages are held at a particular major release number in RH and they will do so for the entire life cycle of that particular version. For example RHEL5.0 came with a 2.6.18 based kernel and RHEL5.7(or however high they go) will also have a 2.6.18 based kernel. However they do back patch those versions with updated security and hardware support. The current kernel (2.6.18-128.4.1) is in reality much closer to a vanilla .26 kernel than it is to a .18 vanilla kernel(both in security and hardware support). This is the way many packages are handled in RHEL.

Edit: If you want to use 3rd party repos rsync3.0.6-1 is available from rpmforge.

Red Hat backport security fixes therefore 2.6.8 on Red Hat is not really the same vanilla 2.6.8 you find on the rsync website.

See:
