If you run Ubuntu or other Linux system using the UFW firewall mechanism, and you probably want to limit at least some ports to only receiving traffic from CloudFlare's proxy servers. CloudFlare provides scripts for iptables, but not for UFW. But they do provide their IP list in a handy format. So here is all you need to do...

cd /tmp
wget https://www.cloudflare.com/ips-v4 -O ips-v4-$$.tmp
wget https://www.cloudflare.com/ips-v6 -O ips-v6-$$.tmp

for cfip in `cat ips-v4-$$.tmp`; do echo "ufw allow from $cfip to any port 80 proto tcp"; done
for cfip in `cat ips-v6-$$.tmp`; do echo "ufw allow from $cfip to any port 80 proto tcp"; done```

Notice this doesn't take action, it produces a handy human readable set of ufw instructions that you can audit before running. Just copy the output to a file and "bash file" to take action. Make sure to set the port to 443 in most cases, or run twice, once with 80 and once with 443.

@EddieJennings yeah, that would be nice for sure.

@CCWTech they serve little purpose in the modern world. It's just the network domains that are automatically tried when you put in a URL with only the hostname and leave off the network name. Which no one does, so it's unused. It's not a LInux thing, it's a general networking thing so the same on desktops, Windows, wherever. Just a standard part of DNS, but like many DNS functions, one that is mostly a vestige.

If you use Active Directory on Windows, it fills it at least one search domain automatically. Windows is about the only place to see search domains still used frequently. This is primarily used for when Linux is put onto legacy style Windows based LAN networks.

@travisdh1 said in OpenAI ChatGPT 4.1 vs 4.5 Models:

This is a somewhat surprising because all the recent reviews I've read or heard claim o3 and o3-mini are the best models so far at least for programming purposes. Are 4.1 and 4.5 newer than o3?

Much newer, 4.1 is actually the newest, very confusing. 4.1 is the most up to date. But a much smaller model.

@Obsolesce said in OpenAI ChatGPT 4.1 vs 4.5 Models:

@travisdh1 o3 is for the best advanced reasoning.

Right o series are reasoning models. GPT are intelligence models. o for strategy, GPT for tactics.

This thread makes me so happy we run all Ubuntu and MacOS around here. Not a single official Windows instance. woot woot

@CloudKnight said in User profile migration to new Windows 11 PCs:

Hasn't Windows become a shitshow.

Always was, they just used to be able to claim that the alternatives didn't exist, even though they did. Now, the alternatives are too public and people are more aware that Windows isn't on par. But as someone who came from UNIX and discovered Windows later, Windows has never been good enough to justify, never been "good", never been anything but a joke. Just people re starting to wake up to it because MS isn't putting the resources into hiding it anymore.

We use Vultr and are very happy. We've moved away from TacticalRMM to FoxRMM, our in house product (aka SodiumSuite.)

Vultr is one I've used in the past, but the pricing is on-par with Linode.

One major difference now that Linode has been bought by Akamai is the storage IOPS. I've run a couple tests, and they are using some sort of SAN instead of VSAN now. IOPS always max out at what you'd expect from a 200Gb network connection.

I might have to try out OVH Cloud. The price for 4vcorse and 8GB RAM starts at ~$5.00/month instead of the $25.00/month I'm currently paying at Linode.

Vultr is using NVMe locally for nodes as it should be. Blazing fast.
