  • 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.






  • But is it decentralized? Do the results from multiple spiders get added to give everyone the same quality searches or do I need to scan the whole internet myself?

    [edit] I was looking at this earlier and couldn’t find the info. Started searching again just now and found it immediately… of course… (The answer is YES)

    Yep, that’s exactly what I was looking at (https://github.com/searx/searx). As I said, it was a QUICK dive but the wording was enough to make me shy away from it. For all the years I’ve been running servers, I won’t put up anything that requires the latest/greatest of any code because that’s where about 90% of the zero-days seem to come from. Almost all the big ones I’ve seen in the last few years where things that made me panic until I realized that oh, if your updates are more than a year old then none of this affects you. And the one that DID affect me had already been updated through a security release.

    I just did a quick dive into this and have some concerns. SearX appears to no longer be maintained and was last updated three years ago. SearXNG was forked to use more recent libraries but there were concerns that those are not always stable or fully vetted. There were also concerns that SearXNG did not follow the same concerns for user privacy. It’s a shame that SearX shut down, that one actually sounds like a project I would have jumped on.













  • If you want to do it right, try to get a static IP (you may need to get a business account). If your provider doesn’t provide IPv6 to static IPs, go to some place like Hurricane Electric and get a free IPv6 range pointed to your IPv4 static address.

    Alternatively, you might do a search for any DDNS services that provide IPv6 (I’m not sure if any do?), then that service will fllow your residential address when it changes. Either way I think you’ll have some additional costs you need to weigh against your current hosting provider.
