DNS / Re: New addresses for b.root-servers.net per 2023-05-16
« on: February 02, 2024, 11:03:20 PM »
Time to transition over to AlmaLinux or Rocky (or whatever EL8 or EL9 distribution you prefer. CentOS 7 is coming up to EOL and CentOS 8 Stream is a non-starter for servers.

CSF Firewall / Re: Release firewall by domain
« on: February 02, 2024, 04:31:47 AM »
Or back to my link above, it references dynamic DNS. So each end client could run dynamic DNS update software (if their IPs are truly dynamic) and CSF can whitelist those dynamic DNS names. What is the scale we are referencing? 10 users? 100?

You can whitelist domains in CSF:

If your client has a static IP, you can whitelist them by IP address.

CentOS-WebPanel GUI / Re: the memory is constantly busy...
« on: January 31, 2024, 06:18:05 PM »
Wow, can I have your server? 50GB of memory, pretty sweet. Two CWP servers I manage has 6GB to the VMs; another has 10GB for the VM. A "dedicated" server has 16GB. Haven't had memory issues with any of them. Seems as though you're going to need to find your memory leak:

PHP / Re: php-fpm83 not installing well / working
« on: January 30, 2024, 11:52:11 PM »
Funny, I had the opposite experience: 3 years ago some early bugs & troubles, esp. in migrating cPanel sites. But then after those early hiccups, it's largely been smooth sailing and once past the initial learning curve, you can lean on the stable CentOS foundation and ride mostly smoothly.

Even in code blocks, some sensitive filesystem paths are blocked by the forum so you have to put spaces in:
/ etc / nginx / conf.d / vhosts / *.conf
/ etc / my.cnf
/ etc / nginx / conf.d / vhosts / *.conf
/ etc / my.cnf

Apache / Re: Some sites (Wordpress) suddenly are not accessible
« on: January 30, 2024, 02:28:03 PM »
Great, glad you got it sorted. Sometimes browser auto-fill overrides your input on forms -- if you don't catch it before saving, you could commit bad input. Probably a sanity check requiring a period in the domain field would be good on the part of the CWP devs. (Gone are the glory days of a 2 or 3 character TLD -- 24 characters max currently!)

Local browser issue (blocking trackers/cookies)? Ad blocker? Try in Private Mode or another browser...

CentOS 7 Problems / Re: Website has no address
« on: January 26, 2024, 11:20:50 PM »
I get NX not found on the domain you listed -- so no valid DNS is in place. Are you using CWP for DNS or delegating to another provider at your registrar level? (Personally, I use Cloudflare for domain registrar, DNS and caching purposes.)

E-Mail / Re: Roundcube - Database error connection failed
« on: January 25, 2024, 07:44:50 PM »
Create a dummy DB if you don't use it. I personally leave the default kit in place if I don't make use of some facility -- best practice so you don't break CWP if it expects something by default.
701
I usually use Cloudlfare's DNS servers (1.1.1.1, 1.0.0.1). But best practice is to have DNS from multiple providers, such as Level3 (4.2.2.2) and Quad9 (9.9.9.9) -- chosen for reliability and ease of memory. Somehow I've always avoided using Big G's DNS servers for my servers -- fine for end user use (but even there I recommend OpenDNS or Cloudflare's filtering DNS 1.1.1.3, 1.0.0.3).

Information / Re: What happened to CWP
« on: January 23, 2024, 07:28:19 PM »
Maybe server upgrades or a hung process? I had trouble getting to the forum last night. All seems well today...

Google is reporting that Spamhaus lists your IP as an open resolver -- did you look up the link Gmail was sending back to you for more information?
Your ports/firewall look correct, but I would suggest switching to https on 2031 for CWP as soon as you get your SSL certificate.

Are you in Toronto? Spamhaus is showing open resolver and is listing 2 different IP addresses. What is your domain name?

I've been down self-hosting before on a biz class connection, even on EPB Fiber (#2 in the nation after Google Fiber) and it is quite a job. Maybe a valuable learning experience, but I don't want to relive it. If it says anything, my servers are now co-located in Las Vegas and Milwaukee -- now I have a symmetric gigabit internet backbone connections, professional routing management, power switch control panel, industrial battery backups and diesel generators -- all for far less than what my business connection was costing.
