Frankly these are useless. SSH is secure by default and will never support algorithms that could be possibly broken. Same for TLS 1.3
If you disable password authentication, and use public key authentication, yes.
The reason for downvotes is comparing apple and oranges, and also throwing FTP in the mix!
Let’s consider SFTP and nextcloud. SFTP is a secure respected protocol for file transfer. If you use key authentication and disable the password authentication, it approaches to be bulletproof security wise. SSH has rarely had a vulnerability that would allow attackers in. It’s even have post quantum cryptography. It’s rather easy to set up. But it doesn’t do more than file transfer. It also doesn’t have a lot of GUI apps.
Nextcloud is like Dropbox. You can find A LOT of things in it (though frankly the quality of most of them may be low). File transfer is just one of the things that it does. It uses https, why? Because the web technologies and developers have focused on this versatile protocol in the past decades. You access internet through port 443 not 22!
If I want to backup data or transfer files, I use SFTP. Over the internet, I trust SFTP not nextcloud. For other things, I use other tools such as Synchting, nextcloud etc. Synchting allows syncing over SSH.
I had proxmox with unattended updates in VMs, but VMs sometimes hangstop booting, encounter DNS issues, etc. That’s not something that I can rely on!
I want to run a vm and make sure the service in it is always available. The users should always have access to the service through Cloudflare tunnels. The bare metal installation works for a long time, but not VM installation. I can tolerate a 30 minutes fix once year, but it won’t work telling users sorry there is a problem this week with my server!!!
How to set up this VM?
So far, the solutions that I found are, set up automatic ZFS snapshots every 15 minutes, and set up another proxmox server with proxmox backup server, ready to boot from backup.
I would like to open an instance of a web server such as nextcloud, synology, etc to the internet. VPN is not possible since recipients are not a prior known. Reverse proxy seems like a good option.
Cloudflare tunnels provide a layer of authentication in front of the web server. But I don’t want Cloudflare having access to my traffic and don’t know a way to add a layer of encryption to keep Cloudflare out of traffic.
I know authelia, but haven’t worked with it.
What are the options?
How do you compare Caddy with nginx proxy manager?
Yes. For example, I want to share all emails on a particular person.
The emails can be easily browsed, searched, etc. I don’t want to share my entire inbox.
On Linux , is there a software to filter, download and catalogue all emails from and to someone?
It would be something like an inbox in Thunderbird, with only one email address. The search brings To or From, also doesn’t store them in a separate folder.
I’m referring to ZERO DAYs. OpenSSH is a serious security product. Those web apps are written by random people and probably riddled with vulnerabilities not known to public.
Here is the rule. Only a trusted vpn and ssh key authentication can be public.
You are doing it wrong: SSH with key authentication is the most secure piece, and could even be public. Immich and Jellyfin surely have zero days and should be behind VPN
