    [TUTORIAL] How-To -- Lets Encrypt and PMG

    Hello, Is this only for a fresh install of Proxmox? I only as because I did some server hardening and installed fail2ban. When I tried to install letsencrypt, it will not let me. I am assuming it pertains to something done in post-install? I appreciate any input you can provide. Robert

    Ubuntu File/Media Server (NAS) on Proxmox

    I have not yet used Docker for services like Plex and NextCloud, but quite a few others, and my experience is that any individualized changes and setup are always stored in config files which are not part the container itself. Isn't that kind of the whole point of docker containers? It is then...

    Ubuntu File/Media Server (NAS) on Proxmox

    ...I don't need to individualize anything. Nextcloud and Plex are things I never would want to be dockerized. There are so much tutorials on hardening security and optimizing performance of Nextcloud by using OPcache + Redis as Cache, optimizing MySQL, optimizing PHP FPM, auto creating SSL...

    [SOLVED] Can't edit any resources via GUI since the last update. Why?

    Found it. We had a hardening on our nginx reverse proxy that got activated with the last reboot. This is the cause: add_header Allow "GET, POST, HEAD" always; if ( $request_method !~ ^(GET|POST|HEAD)$ ) { return 444; } May I ask what additional HTTP method we need to include? Thanks!

    I am desperate trying to configure a proper VLAN on my server

    ...but changing - especially for management pruposes - vlan 1 to something else is considered best practice and mentioned in probably every hardening guide. I'm also certain you can change the vlan in your USG. So, if your server has multiple NICs then you can just bind them to separated vmbrs...

    PMG 6.1 how to add antivirus?

    I remember, I had both on my list too, but F-Secure I mean to remember was also expensive and Eset was one of the solutions, which looked fine, but not official supported any more, you just can find "old" deep links. Dr.Web only looked to be affordable, demonized and still supported, however, I...

The account works fine. However, the auto-shell login in the Proxmox GUI is tied to the root account. How do I setup...
