Yea, I don’t think this is necessarily a horrible idea. It’s just that this doesn’t really provide any extra security, but the even first line of this blog is talking about security. This will absolutely provide privacy via pretty good traffic obfuscation, but you still need good security configuration of the exposed service.
If I understand this correctly, you’re still forwarding it a port from one network to another. It’s just in this case, instead of a port on the internet, it’s a port on the TOR network. Which is still just as open, but also a massive calling card for anyone trolling around the TOR network for things to hack.
This isn’t about social platforms or using the newest-hottest tech. It’s about following industry standard practices. You act like source control is such a pain in the ass and that it’s some huge burden. And that I just don’t understand. Getting started with git is so simple, and setting up an account with a repo host is a one time thing. I find it hard to believe that you don’t already have ssh keys set up too. What I find more controversial and concerning is your ho-hum opinion on automated testing, and your belief that “most software doesn’t do it”. You’re writing software that you expect people to not only run on their infra, but also expose to the public internet. Not only that, but it also needs to protect the traffic between the server on public infra and client on private infra. There is a much higher expectation of good practices being in place. And it is clear that you are willingly disregarding basic industry standard practices.
Github and Gitlab are free, and both even allow private repos for free at this point. Git is practically one of the first tools I install on a dev machine. Likewise, git is the defacto means of package management in golang. It’s so built in that module names are repo URLs.
Git was literally written by Linus to manage the source of the kernel. Sure patches are proposed via mailing list, but the actual source is hosted and managed via git. It is literally the gold standard, and source control is a foundational piece of software development. Same with not just unit tests, but functional testing too. You absolutely should not be putting off testing.
Gotta be honest, downloading security related software from a random drive is sending off sketchy vibes. Fundamentally, it’s no different than a random untrusted git repo. But, I really would suggest using some source control rather than trying to roll your own with diff archives.
Likewise, I would also suggest adding in some unit and functional tests. Not only would it help maintain software quality, but also build confidence in other folks using the software you are releasing.
I have a similar issue when I am visiting my parents. Despite having 30 mbps upload at my home, I cannot get anywhere near that when trying to access things from my parents house. Not just Plex either, I host a number of services. I’ve tested their wifi and download, and everything seems fine. I can also stream my Plex just fine from my friends places. I’ve chalked it up to poor (or throttled) peering between my parents ISP and my ISP. I’ve been meaning to test it through a VPN next time I go home.
Here’s a drawing of what I think might be happening to your private traffic: traffic diagram
One major benefit to this approach is CloudFlare does not need to revoke an entire public certificate authority (CA) if a singular private tunnel’s Certificate Authority is compromised.
I somewhat wonder if CloudFlare is issuing two different certs. An “internal” cert your servers use to serve to CloudFlare, which uses a private CA only valid for CloudFlare’s internal services. CloudFlare’s tunnel service validates against that internal CA, and then serves traffic using an actual public CA signed cert to public internet traffic.
Honestly though, I kinda think you should just go with serving everything entirely externally. Either you trust CloudFlare’s tunnels, or you don’t. If you don’t trust CloudFlare to protect your services, you shouldn’t be using it at all.
Just serve the CloudFlare certs. If the URL is the same, it won’t matter. Doesn’t matter if you’re talking to a local private address like 192.166.1.100 or a public IP. If you’re accessing it via a DNS name, that is what is validated, not the underlying IP.
PS. If you tried this and are having issues. We need more details about how things are set up, and how you are accessing them.
I think I misunderstood what exactly you wanted. I don’t think you’re getting remote GPU passthrough to virtual machines over ROCE without an absolute fuckton of custom work. The only people who can probably do this are Google or Microsoft. And they probably just use proprietary Nvidia implementations.
I believe what you’re looking for is ROCE: https://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet
But, I don’t know if there’s any FOSS/libre/etc hardware for it.
If you are fine with the slim: US amazon.
I’ve heard good things about used/refurb HP (elite desk and pro desk) and Lenovo (m700 and m900) mini-pcs. A quick search shows they’re going for ~120-140$ for a quad core with 16 gigs of memory.
Check out minisforum, for example this intel mini-pc. They have a ton of selection, not just that one example.
In the LastPass case, I believe it was a native Plex install with a remote code execution vulnerability. But still, even in a Linux container environment, I would not trust them for security isolation. Ultimately, they all share the same kernel. One misconfiguration on the container or an errant privilege escalation exploit and you’re in.
You are not being overly cautious. You should absolutely practice isolation. The LastPass hack happened because one of their engineers had a vulnerable Plex server hosted from his work machine. Honestly, next iteration of my home network is going to probably have 4 segments. Home/Users, IOT, Lab, and Work.
Keep in mind, RAID is fault tolerant, not fault proof. For critical data, keep in mind the 3-2-1 rule. Stored in 3 locations, 2 separate mediums, 1 offsite.
Annoying yes, but I’d argue that’s likely the simplest and most performant approach. At best (IPTables NAT), you’d be adding in an extra network hop to your SMB connections which would effect latency, and SMB is fairly latency sensitive especially for small files. And at worst (Traefik), you’d adding in a user-space layer 7 application that needs to forward every bit of traffic going over your SMB connection.
In general, container root filesystems and the images backing them will not function on NFS. When deploying containers, you should be mounting data volumes into the containers rather than storing things on the container root filesystems. Hopefully you are already doing that, otherwise you’re going to need to manually copy data out of the containers. Personally, if all you’re talking about is 32 gigs max, I would just stop all of the containers, copy everything to the new NFS locations, and then re-create the containers to point at the new NFS locations.
All this said though, some applications really don’t like their data stored on NFS. I know Plex really doesn’t function well when it’s database is on NFS. But, the Plex media directories are fine to host from NFS.
