Hello Mark,
I’m using and configuring my domain with CloudFlare/virtualmin and would like to be able to use virtualmin and postfix so that applications on my server (like vaultwarden for example) can send emails securely via selhosted SMTP.
Being a little lost in this jungle, could you do a detailed tutorial with screen for :
DNS/Cloudflare configuration (SPF, MX, DKIM, DMARC) Activate email on a virtualmin domain with postfix Configure email postfix on virtualmin and postfix Configure firewall for emailing (virtualkmin) TestingThank a lot in advance.

Hello mark
It’s strange this evening I no longer had SSL access to my dev environment
I had a zeroSSL CA certificate that was still valid until the end of the month.
I rebooted the machine as well.
So I checked my DNS, Cloudflare, domain name, nginx service, all is OK.
I regenerated a certificate on zero SSL but I got an error saying there is a problem with the certificate (invalid certificate)

From time to time, here or there, we see subjects flourish on an abnormally limited speed in FTP.
To overcome this kind of slowdown, simply activate the TCP BBR protocol
Without going into details, this protocol makes it possible to make better use of the bandwidth available during the exchange of TCP packets. Created by Google, you can find more information here.
Integrated into the Linux Kernel since version 4.9, all you have to do to activate it is to edit the kernel parameters (/etc/sysctl.conf) and add :
net.ipv4.tcp_congestion_control = bbr net.core.default_qdisc = fqA TCP command acting in both IPv4 and v6,
save and load with :
sudo sysctl -pAnd we go from a restricted FTP speed
crazy 🙂
If you are under Proxmox or ESXi, this must be done both on the host and in the VM/CT.

Hello @all @phenomlab
NodeBB haven’t got a great chat plugin or native chat system.
Global chat plugin is very good but he haven’t got moderation tools and it’s a problem.
For my test, I research a good IRC server for Debian 11 to install on my VM.
I would like to have Moderation Tools and a GUI for the Configuration (Moderation ,channels etc…)
For the Client, I have install The Lounge on the VM, it’s a server client IRC wirth GUI, he is very great 😉
There may be better than IRC servers/clients, but the IRC server/The lounge combo has the advantage of being quite simple without necessarily having user databases.
Afterwards, if we have a app or system that can interface with the NodeBB user database, that would be great. (IRC server too)
Thanks my friends

Hi, i see plesk is more easy to handle the server and i would like to go with plesk but will have have full ssh control over server? I can install redies right?
I agree both will have their own advantages and disadvantages but most likely i will only run flarum in this droplet and I will be needing light speed cache, somone has developed a extension for flarum
Hello how can I enable root login in debian 11? “PermitRootLogin yes” doesn’t seem to work anymore
Hello and thank you in advance for your help.
I am running a Digital Ocean Droplet with Ubuntu Server 20.04. I have Virtualmin, Webmin and the package for that setup. I have the same setup for a dev platform that I test before making update live on the production server. I am also using pm2 to run my node applications with a proxy website under the domain in virtualmin pointing to http://127.0.0.1:PORT.
I am having trouble on where to put environment variables.
I have tried this location and the variables just don’t work. In my node app I am using process.env.VARIABLE.

I have also put variables in /etc/environment and have created a sh file with the variables in /etc/profile.d folder.
I am not sure what I am doing wrong or if I need to be adding these variables in a totally different spot. I have done hours of research on the internet. The current solution that I have somewhat working is putting the variables in both /etc/environment and /etc/profile.d/myvariables.sh.
In /etc/environment I am using the following format:
VARIABLE_NAME=whatiwantthevaluetobeIn the myvariables.sh I am using the format below:
export VARIABLE_NAME=whatiwantthevauletobeI am lost and need some help getting back on the path and the proper way to make this work. Let me know if you need any other info and thanks again for the help.
Hello guys, i’m back!
to learn how to manage a droplet, i’ve buyed a new server at digitalocean and migrated (under construction) my old justoverclock website to a ghost cms (that is so difficult to configure for me).
the website works (but is half english and half italian for now, idk how to translate).
and now i’m about to install flarum but i have “experience problem”. first of all i’ve installed mysql (i think is ok).
and i want to install php my admin because i know how to use it. but i can’t install apache, it doesnt work following the various resource on internet…i’m really frustrated and stucked.
is my very FIRST experience with droplet so be gentle if i made stupid questions.
Unable to ping ip or host in linux
I get this error
ping: sendmsg: Operation not permitted
I tried all the solutions listed on google none of them worked for me can anyone help me ping work in my ubuntu?
with the help of Mark i have a flarum instance on forum.justoverclock.it.
i’ve noticed that i can’t post if blomstra realtime is installed.
following the guide i’ve installed supervisor…but i can’t get it to work…i need to add something else?
Hi,
When I run “sudo systemctl restart apache2”
It says: Job for apache2.service failed because the control process exited with error code.
after I run “sudo journalctl -xe”
It returns with a lot message, which are all the same, as following: I wonder is my server get attack by the following IP, “31.130.184.78”? 🙂
I believe that I haven’t made any settings for my virtualmin server. Can anyone please tell me what are the basic settings to protect my server.
