Arch Server Progress

    @phenomlab Yeah, they are both very challenging. I’m not completely done with setting them up yet and have a ways to go. I can see how using Webmin/Virtual min is really nice because they take care of all that stuff for you. It is nice to learn and see how everything works under the hood. I don’t know if I will remember all of it, but I have enjoyed going through this process.

    I am able to send emails from my server now, so I am doing something right, hahaha! I would say that I am about 1/2 way done with the whole email server setup. This has been spending anywhere from 2 to 4 hours on it at a time. My schedule doesn’t allow me to sit and get it done all in one day. I never realized how involved and time consuming setting up an email server can be.

    I just installed Redis today and am using that for caching with the two Wordpress sites that I have on my server. I wanted to install Redis anyways in case if I ever start using Nodebb I can have the multiple sessions going to make it faster.

    The wordpress sites run super fast as well after adding and configuring them to work with Redis. I need to configure Redis a little more but for the most part it is working great.

    @Madchatthew yes, it takes time, but no so much once you grow accustomed to the process. After a while you get a sense of what will work and what will not, and it also pays - certainly in the sense of PostFix to keep a golden configuration file that you know works.

    It’s disturbingly easy to take PostFix offline with one single mistake.

    @phenomlab yeah I have been reading about that as well in regard to Postfix. One little piece forgotten or changed in any little way can topple the whole thing down haha. It is crazy. And also, thank you for reminding me that once I get everything working and running to make a copy of those config files. That will help in the future and just may save my bacon.

    I wanted to give an update on this. I have been working on trying to get a postfix, dovecot along with a couple of other programs working on this server. So far I have been unsuccessful. I am not giving up though and plan on starting a new thread to document each step that I take. Maybe someone will be able to see my mistake that I made or what I am missing and be able to help figure it out.

    I know it would be easier to just go through one of the mail websites that are out there, but I would really like to learn this process.

    Well, I must say that I was finally able to get email working on my Arch server. I still need to setup postgrey and some spam assassin, get the dmarc and spf and one or two others setup and then it should be good to go for the most part. I am mainly using it to be able to send mail from websites, but having the option to have a separate email for their domains will be very nice.

    Once my brain solidifies after all of that, I will share what what I did. One thing I found is that it is important to just take it piece by piece and get each part working before moving on to the next. Also, test test test after each change, or each section.

    I also wanted to post this. Here are the latest stats for the server so far. This is with all of the software setup and running along with doing updates once a week after testing them on my dev test server and making sure websites function properly.

    @DownPW 🙂 most of this really depends on your desired security model. In all cases with firewalls, less is always more, although it’s never as clear cut as that, and there are always bespoke ports you’ll need to open periodically.

    Heztner’s DDoS protection is superior, and I know they have invested a lot of time, effort, and money into making it extremely effective. However, if you consider that the largest ever DDoS attack hit Cloudflare at 71m rps (and they were able to deflect it), and each attack can last anywhere between 8-24 hours which really depends on how determined the attacker(s) is/are, you can never be fully prepared - nor can you trace it’s true origin.

    DDoS attacks by their nature (Distributed Denial of Service) are conducted by large numbers of devices whom have become part of a “bot army” - and in most cases, the owners of these devices are blissfully unaware that they have been attacked and are under command and control from a nefarious resource. Given that the attacks originate from multiple sources, this allows the real attacker to observe from a distance whilst concealing their own identity and origin in the process.

    If you consider the desired effect of DDoS, it is not an attempt to access ports that are typically closed, but to flood (and eventually overwhelm) the target (such as a website) with millions of requests per second in an attempt to force it offline. Victims of DDoS attacks are often financial services for example, with either extortion or financial gain being the primary objective - in other words, pay for the originator to stop the attack.

    It’s even possible to get DDoS as a service these days - with a credit card, a few clicks of a mouse and a target IP, you can have your own proxy campaign running in minutes which typically involves “booters” or “stressers” - see below for more

    @DownPW said in Setting for high load and prevent DDoS (sysctl, iptables, crowdsec or other):

    in short if you have any advice to give to secure the best.

    It’s not just about DDos or firewalls. There are a number of vulnerabilities on all systems that if not patched, will expose that same system to exploit. One of my favourite online testers which does a lot more than most basic ones is below

    I’d start with the findings reported here and use that to branch outwards.

    @phenomlab said in Advantages and disadvantages of changing to Ubuntu?:

    @jac Yeah, I wouldn’t just leap into it unless you have a valid reason (such as the laptop no longer working and needing to be reinstalled). Probably better the devil you know currently.

    Absolutely mate, and generally as discussed that is the only time I have changed over to Ubuntu once the laptop has got slower.

    For now I will carry on with Windows, purchase the VPN & BitDefender in later October / early November and then see how all that runs for a few more months 👍🏻.
