I used pfsense before I was introduced to the edgerouters. Once I learned it was s fork of VYOS and saw how easy it was to learn, and how inexpensive it was, I switched from pfsense and never looked back.

How does that method of making coffee compare to a French Press. That's what I use when I want a decent cup of coffee.

Is anyone running a Wordpress site on a 768 MB instance of Vultr?

For a couple of days after initial setup, I was able to install MariaDB, Wordpress, etc, install a theme and some other plugins, and do some other site config. The site was working without issue. Now, almost all the time, the site just gives a "Error connecting to database" error. Upon further investigation, and watching the console, I figured out that the error is happening because the processes keep terminating (mysqld and httpd). Restarting the services fixes the problem for a couple of seconds, but then the server kills them again. When checking memory, the free available memory right after restarting the database server is extremely low. I'm assuming this is why the servers keeps killing the processes.

Is this just a resource issue? Is a 768 MB server too small for a 1 site wordpress site?

@scottalanmiller Salt will be my first experience with this sort of automation in the DevOps space. Plenty of automation before at previous employers, but nothing related purely to the OS/systems themselves. I'm excited to see what's possible. All your salt posts have convinced me to at least look at it.

So.... about MangoCon 2022 ?

@StrongBad Yep, I've put those in at numerous businesses, and they work great with remote PBXs. Actually, I haven't found anything that they are NOT good at yet for SMBs.

Just updated now using the script. Update worked great, thanks!

A couple of weeks ago we had someone walk into the IT department and say, this is our new hire... do you have a laptop for him? We all looked at each other blankly as no one ever told us that there was a new hire starting that day.

Just convince your HR department to make it part of the "New Hire Checklist." That's what I did back in the day and it fixed it. There were a few times where they still wouldn't let us know in time, but for the most part, it fixed the issue.

Looking at the details page, here is a limitation depending on how you handle client accounts, or your own accounts.

What are the Lightsail service limits?
You can currently create up to 20 Lightsail instances, 5 static IPs, and 3 DNS domain zones in a Lightsail account.

But this is pretty cool. Ability to manage traffic before it hits your VPS:

Can I manage firewall settings for my instance?
.
You can control the data traffic for your instances by using the Lightsail firewall. From the Lightsail console, you can set rules about which ports of your instance are publicly accessible for different types of traffic.

@fuznutz04 I have Plex Pass and IMO it's completely worth it

Yeah, I am sold on the free version for all my DVD rips. I've been using it for almost a year without issues. The family loves it due to ease of use, and I love it because I am sick of seeing DVD cases lying all over the place from my kids.

Has anyone had any issues with and ERX, or ERL just "locking up" and not responding? I have an ERX and an office, and last night the box just stopped responding to all requests, VPN connections dropped, etc. I had to have someone on site go and power cycle it. After that, it came back normal. I've had this before on home grade stuff, but this is now the second time it's happened on my ERX. I'm on Firmware 1.9. But it also happened on 1.8.

Anyone else run into this with the ER line? Logs on the ERX are not showing anything useful.

Disco ball, strobe light & laser beams. Got it.

@Romo Bingo! That did the trick. Thanks!

Vultr now offers an ISO library. Previously, they offered a custom ISO upload feature, which by itself, is of course, awesome. Now, they offer a new feature called ISO library, which from what I can tell, has a lot of other "non VULTRized" ISOs. Examples: CentOS7 Minimal, FreePBX, Ubuntu 16.10, and many more. Announcement from December below.

Introducing the ISO Library
Dec 08, 2016

Custom ISO users now have a new option for mounting ISOs - the ISO Library! The library is curated by our experienced team of system administrators and is updated periodically. Popular Linux and BSD distros are included, making installing a custom operating system on Vultr both quick and convenient.

You can also mount these ISOs directly from your existing Vultr cloud servers. Our Vultr Docs community includes a variety of useful guides that reference Custom ISOs, such as step-by-step tutorials on using rescue images to troubleshoot or customize instances. Save time spent uploading a Custom ISO and focus on what matters most - troubleshooting and getting your cloud servers back up and running quickly!

Need an ISO that isn't in the ISO Library? You can still take advantage of our powerful Custom ISO upload system for your new deployment!

So some new thermal paste, properly applied, brought the full load temp down to 75-80 c during a video encode. Video encode is about the absolute most taxing thing you can do to a process. Problem solved!

@scottalanmiller the videos are great, but audio while driving is the big win for me personally.

@jaredbusch said in Securing FreePBX from attacks:

Your fail2ban is running. This is the responsive firewall doing its job.

It takes multiple attempts in order to block. Most bot designers know this and don't attack many times.

By default pjsip was disabled (above pic was after I enabled). Was anything really gained by enabling it? I imagine the answer is "yes."

In day-to-day administration, do you usually ignore this and let Fail2Ban do its thing, or do you start adding these hosts to the Blacklist with the Firewall > Services setting?

You will die tired adding IPs to blacklists. Just let the responsive firewall and Fail2Ban do its thing.

So we all use mySQL/Maria DB for various open source projects around here. I would like to start a discussion about best practices regarding mySQL. There are a ton of configuration options that you can make in the my.cnf configuration file. Some are very important, while others might not make that much of a difference. One of the things taht make a huge difference in regards to disk space, is the use of binary loging. Most barebone installations of mysql/mariadb, enable binary logging, but do not make any additional entries for log rotation/expiration of maximum file size.

For example: adding these 2 lines to the my.cnf file is really important, if you are in fact using binary logging, and do not want mysql takign up all of your disk space with this.

expire_logs_days=X
max_binlog_size=X

What are some other parameters to optimize mariadb/mysql? It will vary from workload to workload, but it would be great to get a discussion going on this.
