Re: Trouble connecting to wifi, Debian 11
Maybe you should use it because that's where you will find a lot of non free firmwares. Check your kernel logs ($> sudo dmesg) , you may find an explicit reason why your adapter fails to run properly.

Re: How can encrypt my messages sent to the forum?
Hi William, If you want your messages to exchanged securely with SSL, you have to ensure that your SMTP (client,relay,...) use the STARTTLS command of the SMTP protocol. If you want your messages to be encrypted you have to know the public key of your target (if using a public key infrastructure) or find way to share a secret with your target for a symetric encryption. May be someone can tell you if this mailing list provide a public key for GPG. Personally I never checked for this and I hope this will help you.

Re: Securing local host of reverse SSH tunnel?
>Ideally, this restriction should be based on the public key of the pair but I've not seen in sshd_config(5) a way for the Match directive to use the public key as its trigger Not an expert but did you look at the certificate based authentication? You can define your own certificate authority and allow only the certificates signed (it's a public key) by your ca can to connect to your ssh server. 1 - Generate a key pair for the ca ( and another for he remote user) $ ssh-keygen -t rsa -b 4096 -f ~/.ssh/ca -m PEM 2- Sign the public key of the user ssh-keygen -s ca \ -I \ -V 20191220:20201220 \ user_key.pub will be logged on your server everytime a connection is opened with user_key.pub. -v stands for key validity. 3 - Allow on your LAN (ssh server) TrustedUserCAKeys /secure/permission/ca.pub This means, any certificate signed with this ca will be granted access to your server. Of course you can restrict what the users whose login is allowed (particularly prevent root login ). Note: using the certificate based authentication, you can even choose what kind of features are allowed to be used with a particular certificate. a k.a AllowX11Forward and many more. Maybe a good reading of ssh doc may provide you an better approach for your use case. ssh(1) Hope this will help.
Re: ssh key used for login
If what you use is a certificate based authentication, you can add user identity to the certificate with -I . Any auth attempt will make that identity logged automatically. Then you just have to get it from syslogs.

Advice on hardware server to use for small a dedicated data center
I'm very happy to have asked this question here, my brain is enjoying. Thank you again for all, I'll definitely be stick on Debian. > Something seems a little flakey about that architecture. Rsyncng postgress data? There are lots of better ways to merge data into a database. Particularly in these days of cheap, continuous, broadband connectivity. And if you can't get business broadband in all your locations, cellular modems are dirt cheap. (I speak as someone who's designed more than a few mobile data collection systems - everything from tactical military systems to transit buses) Exactly, what a bad idea. Here I should be talking about sync not rsync ( autocorrect killed me). I was thinking about WAL archiving for a point in time recovery. > Rsync is just wrong for that kind of application. What are you syncing, anyway. 2500 postgress instances, some raw data files for input to a single instance of postgress, something else? And if the postgress instance is feeding live data to apps, you really need to focus first on your high-availability strategy - single points of failure will kill you. Not for database but for raw files like images, video and audio, I planned using rsync ( I've not yet tested if git could do the trick here but I thought about it) > As a startup, you've got way too many other things to worry about than home brewing an IT environment - focus on your core product/service, whatever that is Exactly, but when I've seen that the product we are going to build will cover all those aspects a.k.a building this means our product is ready and we gained more experience on the subject. > I added indexes for the relevant fields, and the query took a few minutes.

About the budget an manpower, we are creating a financial plan in order to present it to our investors, so nothing is well decided for the moment, that is why all your answers and suggestions are welcome and very useful. What is ideal for 24/7 operations,high-availability and auto fail-over ? We're 8 in the team for the moment, 2 web and mobile developer and only 2 peoples know things about system and network (admin,security,..) but we plan to get more peoples.

Installing/launching MATE in a command line environment
Hello, If you want the desktop environment to be started automatically check that systemd is configured to run in graphical environment $> systemctl set-default graphical.target If this is already setup, and you can launch your DE with startx, check also that mate is the default DE with update-alternatives(8) or you can add the startx command in /etc/profile.

I already have some raspberry pi running at home and even if I found they can do very many things, they don't match what I want now. I'm currently using the 4b model with 1Gb of RAM which seemed to have enough power for doing much more things but it's not yet able to boot from an external hard drive, but I tried hacking this with fstab and it worked sometimes and not on the next boot, so I just stopped trying to figure out what happened.

I don't really know how to answer to your question but let's try. We are a startup and for the moment we have a production and a development, in fact the production is just like a test environment because we do continuous delivery, we push everyday in order to know more quickly when something has been broken and our semi-automated tests didn't detect it. Personally, I'm a self learner, and probably many guys of my team are too. So some advices here are also welcome. We want to be able to handle 2500+ rsync in the morning (probably distributing them in time in order to avoid a single big load acting as a ddos) and for each client of my clients (restaurants) a get and put profile request.

Advice on hardware server to use for small a dedicated data center
Hello, First of all, please don't ask me why I simply don't want to use aws or gcp. Then, I want to build a small data center for my company for hosting a web app and a mail server. It's the first time I'm going to buy some hardware for this. I tried looking for it on the web in order to compare them but it seems that hardware vendors never want to talk about Debian on their websites. Seriously, I prefer using my money for donating to the Debian foundation than having to pay for Ubuntu or Red Hat Enterprise because I love Debian and ... So, I want to know if It's a good idea to try using Debian in an enterprise context, with hardwares like Dell EMC PowerEdge or Lenovo ThinkCenter which seems to never mention that they support Debian. What kind of issues can I encounter with such hardwares except simple cases like having to install missing drivers with some already available firmwares. Can you give me some alternative hardwares in case this idea may take me to much time to solve ? Note: I will need some RAID solution hard or soft. Sorry if my English is bad, it's not my mother language. Thank you.
Re: Are All Drives Installed .
> > Hello, I'm a newbie too, if you want to know if your drivers are installed look at the kernel logs with: $ dmesg If they're not you should see some error/warning messages. By default Debian will not install non free software like proprietary drivers. If this cause your issue, find the related driver and install it. For example, if you use: $ lspci You may find your network adapter named Atheros.* then install atheros-firmeware.deb. hope this help.
