=== chris14_ is now known as chris14 [10:52] hi, i got recommended to this group. I am new to linux and ttrying to find info on building a lean backend server. I came across ubuntu-server & alpine-linux. [10:54] we can only help with Ubuntu here [11:05] ravageĀ  can you tell me how can i learn how I can make my ubuntu server very specific for backend applications like Java , Javascript & MySQL. [11:05] Remove everything that i do not need [11:06] a minimal ubuntu installation does not leave much more than the bare minimum [11:07] install it. install your applications. done. [11:19] help! this happened, for the 1st time, on my dedicated server: https://0bin.xyz/?1a10218c0a6ceb77#8Eam1S9i9Ss1bPdtekADpWDCwcoYm9gj7cSxKoZjtnP9 [11:19] after a `apt update && apt dist-upgrade` [11:24] no is fine [11:24] you still have the old grub on it [11:24] you can figure out why is failed later [11:24] eh [11:24] "yes" in this case [11:24] sorry [11:28] now what do i do to see why it failed? all I can see while upgrading is this: https://0bin.xyz/?24eaf1c008a2de3a#Dp5K7NtbBpzb5MiiNqwpE2Dw9ShStxTuJGF4ufcvnrdx [11:52] ravageĀ  got disconnected. How do you know that the minimal installation does not leave much more than bare minimum? Are you aware of in-depth details? [11:53] Guest76: no. but why dont you just install it and see for yourself? [11:57] ravage Ubuntu runs over a 100 processes. I wouldnt know where to begin [11:57] no idea where you got that number from [11:58] ravagefrom the master ubuntu server book by Jay Lacroix that I am reading. [12:01] https://p.haxxors.com/i78qa8ly.txt [12:01] this is the full process list of a launched Ubuntu 22.04 LXC container [12:02] so its really init and systemd [12:22] ravage Idk what LXC container is but it seems different than Ubuntu desktop. Thats what the book uses to teach. [12:23] and why would you read about a full desktop system if you want a small footprint? [12:23] makes no sense at all [12:27] ravage because I dont even know basic system adminsitration, so it seems like a good place to start and then dive deeper. [12:27] I didnt even know about users and permissions. Now I know [18:25] Hello, I run isc-bind. can you recommend a channel in which for me to ask or maybe some knows, Cache Statistics says CacheBuckets 1024 and CacheNodes 702 and I'd like to know how that roughly translates to entry count. [19:04] jrwren: the bind user mailing list perhaps? https://lists.isc.org/mailman/listinfo/bind-users [19:04] It seems like a very specialist upstream question. You're very welcome to ask here but I'm not sure there's anyone who knows the answer. [19:22] thanks rbasak. i also found #bind. Maybe someone there know. [23:12] so, I'm a bit stupid.. I want to enable UFW but I want to allow ALL traffic except specific IPs. how can I achieve this? [23:22] I suppose that `ufw default allow` and then `ufw deny from IP to any` for each IP will do it?
