Port to listen on - The default rsync port is 873, but can be overridden here.Log file path - Important for error handling, service monitoring, and troubleshooting.Lock file path - Necessary for the daemon to run.Process ID file path - Necessary for the daemon to run.In its simplest form, the nf file declares the following global parameters: Pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsync.log port = 12000 path = /var/storage/ comment = Primary file server timeout = 300 Because each path requires separate configuration, it’s easy for one to fall through the cracks and omit an important directive. Organizations that rely on rsync may find these paths accumulating over time. In service mode, rsync can provide details for many different synchronization paths. The rsync daemon depends on nf for its authentication, access, logging, and available modules. For our purposes, we will focus on rsyncd, which is the most common way rsync is utilized at scale. Rsyncd is the vector for data exposure involving rsync, as it can be opened by an anonymous third party without the proper protection. Rsyncd relies on nf for its configurations, where each sync path has its own block of options. The daemonized version of rsync is known as rsyncd, and listens on a designated port as a service. One is a command line utility where all of the details are passed as argument variables, this is rsync. Rsyncdīefore we dive into the configurations themselves, it’s important to note that there are two different ways to use rsync. Rsync can be a powerful utility for simple file mirroring or transfer, but the level of care taken to configure it should be commensurate to the sensitivity of the data being transmitted. Although rsync can move these files the same as it could if they contained gibberish, the risk to the business can be severe if that information leaks.ĭata exposure has become a prominent business risk, and organizations that have experienced such a leak have also had to endure the associated financial and reputational damage. When rsync is used by businesses, the government, and other large organizations, the files being transferred may contain extremely sensitive information. They only do what you tell them, and in the case of most Linux-based utilities, only exactly what you tell them. They don’t know sensitive from not sensitive, and they don’t separate out dangerous from harmless. But like many pared-down tools, it does not invoke them by default, and the burden therefore rests on the person setting it up to configure it securely. This type of file copy procedure is extremely common for most organizations, and without process guidelines, techniques and utilities vary widely among individual admins.ĭespite its compact build, rsync does have security options that can protect the data it transfers. After that first sync, rsync will only move the changes, keeping the mirror identical to the primary server and minimizing network traffic. For example, if you set up rsync on a file server and connect a backup server as the mirror, the initial sync will move every file in the specified path. One of the great advantages of rsync over other similar utilities is that it is able to easily transfer only the delta between systems.
To successfully use rsync in the enterprise means protecting the data being transferred through it from accidental exposure.
But this same asset is also a liability for many utilities: designed purely for functionality, they may not automatically account for potential risks to enterprise data. Its lightweight build, small footprint, and usability make it a good choice for simple file copy operations. Linux sysadmins have been using rsync (remote synchronization) to move and mirror files for two decades, though versions of it now run on nearly every platform. Some of these technologies are pricy, big-name business solutions, but some are simple tools and utilities, facilitating processes. Modern enterprise data centers are a complex mix of different technologies geared towards accomplishing business goals.
