But why doesn't it ever empty the swap space? I've been using vm.swappiness=10 and I've tried vm.vfs_cache_pressure at 100 and 50. Checking ps I'm not seeing any services that would be idling in the background, so I'm not sure why the system thought it needed to put anything in swap. (And FWIW, I run two servers with identical services that I load balance to, but the other machine has barely used any swap space -- which adds to my confusion about the differences).

Why would I want to reduce the amount of memory in the server? Isn't all that cache memory being used to help things run smoother and reduce drive I/O?

And how does cache space figure in to this? I have a server with 64GB of RAM, of which 46GB is being used by system cache, but I only have 450MB of free memory and 140MB of free swap. The only 'volatile' service I have running is slapd which can run in bursts of activity, otherwise the only thing of consequence running is webmin and some VMs which collectively can use up to 24GB (though they actually use about half that) but there's no reason those should hit swap space. I just don't get why the swap space is being run dry here.

So ldirectord is kind of a front-end for ipvsadm. The tools allow you to set up load-balancing between internal servers. I run each service in a VM, and I have at least two copies of each (on separate physical servers). Ldirectord lets me configure how frequently to verify each machine is up, a list of primary servers, and an optional backup when the others go down. Overall it works pretty smooth.

Shorewall is similarly a front end for iptables, allowing a more structured set of configuration files. I've been trying to start using Webmin for the first time because it has some nice management of shorewall, maybe I'll be able to clean up some of my config, but I'd also like to get traffic shaping configured.

I have a dedicated firewall (just moved to a poweredge R620 last night), a NAS, and two VM systems to run services on... all run from home. I enjoy setting things up to play with, so this has all been built up starting from old desktop machines and expanded over time.

I tried playing around with opensense awhile back. Wasn't impressed and kept running into things I couldn't get it to do for me, so I stuck with my existing setup. I use ldirectord for load balancing between servers and shorewall lets me generally balance the traffic between WAN connections. It works pretty well but there's a lot of moving parts.

Does anyone else use a Linux firewall to manage dual connections? I run Shorewall here, but I haven't really had much luck with traffic shaping to keep the majority of traffic on my primary connection while allowing low-speed info like email to split up between connections.

This right here is the main reason why Trump might succeed... The media has been beaten into submission and refuses to report the actual events that are occurring which make Trump look bad.

God that article was a horrible read. So for anyone who wants to skip it...

tl;dr: Hackers are using SSL certs from 2012 and changing the unprotected system clock in order to bypass security measures.

If your card has an x4 pinout, then it probably needs the additional bandwidth. Plugging it into an x1 slot (if it was possible) would slow down the network traffic. Get a better motherboard with an x4 slot on it so you can use the hardware you want. or find something else that will fit your computer.

Honestly even the 1Gb quad port card I have requires an x4 slot, although I saw some dual-port 2.5Gb x1 cards on ebay. Maybe you could just use two of those?

You didn't see the quote in the above comment that specifically states Teslas don't have lidar but other brands using it weren't fooled?

Trump Derangement Syndrome -- When you are so infatuated with Dear Leader that you will do anything for him, say anything to defend him, and try your best to be just like him.

And to absolutely nobody's surprise, Twitter was NOT asked to testify about their long and proven censorship of content when Trump or Musk are called out for direct lies in favor of the Trump campaign, and hiding content in favor of Biden/Harris. But noooo, this administration would never use the justice department for retribution. /s
