rsync VS tailscale

So we have our SSH connection all oiled and ready to go. In the next post on the series, we will see how can we use Rsync to sync our music files, bidirectionally. See ya, on the next tab.

Rsync is a command-line tool that enables syncing files and directories between the local and remote system. It's highly flexible and it's similar to scp, if you worked on scp before, the rsync is just scp on steroids.

rsync can be used to synchronize a local disk to the pCloud drive p. Works similarly as the Sync option of the pCloud Drive app. May be useful if one prefers a bulk upload once a day over a continuous synchronization.

Tools that can be used to handle this include Rsync, Duplicati, Cohesity

To overcome this issue, you can use rsync, a powerful command-line tool for synchronizing files and directories, along with a bash script that excludes the node_modules folder and also filter out anything in a .gitignore file that you specify. In this article, I'll guide you through the process of setting up and using this bash script to sync your Node.js project while ignoring the node_modules folder.

On OL9 I installed rsync using https://github.com/WayneD/rsync/blob/master/INSTALL.md and installing dependencies using the For Fedora 33 commands where possible except xxhash which wasn't found, so I used https://oraclelinux.pkgs.org/9/ol9-codeready-builder-aarch64/xxhash-devel-0.8.1-3.el9.aarch64.rpm.html

rsync will probably work better for this use case

I would prefer to use a revision control system, like git if keeping multiple versions of documents is important. Otherwise, if you don't find anything else to your liking, you could write your own scripts based on rsync with the clone-dest, detect-renamed, and detect-renamed-lax patches.

Give rsync a try, it should handle UTF filenames just fine.

> VPN as a service sounds wrong from security perspective, as you are giving away all the keys.

Tailscale’s Android and Linux clients are open-source[0] and based on WireGuard (which AFAIU is now part of the Linux kernel[1]). With other VPN software you may be owning the keys but you cannot verify what the program does.

Tailscale requires a coordination server to function. This component is not open-source, but there is an open-source reimplementation called Headscale[2] that you can host on your own server.

Additionally, there is "tailnet lock"[3]:

> Tailnet lock lets you verify that no node is added to your tailnet without being signed by trusted nodes in your tailnet. When tailnet lock is enabled, even if Tailscale infrastructure is malicious or hacked, attackers can’t send or receive traffic on your tailnet.

> These internal services that are annohnced are just... Services you can run on the Internet with TLS.

I haven’t used Tailscale in a professional context, so I cannot comment on the usefulness there, but I am using it (with Headscale) in my homelab. It makes it very easy to access all the services spread onto multiple boxes from everywhere, let them all use the same AdGuard Home DNS server without having to configure them individually and tunnel all my traffic through my home internet connection using an exit node[4].

I normally use croc[5] for file transfers between boxes, but when I had to fetch some files from my Windows game streaming computer, it was easier to just use Taildrop because Tailscale was installed already.

BTW, that code changed just recently:

https://github.com/tailscale/tailscale/commit/1c972bc7cbebfc...

It's now a AF_PACKET/SOCK_DGRAM fd as it was originally meant to be.

I recommend checking out [Caddy](https://caddyserver.com/), which replaces both Nginx and Certbot in this setup.

[Tailscale](https://tailscale.com/) can remove the need to open port 22 to the world, but I wouldn't rely on it unless your VPS provider has a way to access the server console in case of configuration mistakes.

Anyways, I'm not always at home when I want to work on something and I wanted to find a way to access services remotely. Well tonight I realized I should be able to do this with Tailscale.

Looks like it's due to this: https://github.com/tailscale/tailscale/issues/6999#issuecomm...

It's important to note potential edge cases when integrating Calico with Tailscale as discussed here. To avoid conflicts, we recommend remapping Calico's netfilter packets. This ensures compatibility and smooth operation in your network setup.

‍Tailscale simplifies network management, enhances security, and facilitates remote collaboration, ultimately enabling them to focus on their core development tasks without worrying about networking complexities.
