[02:16] <Yakov> how to make ubuntu standard screenshot using cmd?
[02:17] <rbox> gnome-screenshot
[02:17] <Yakov> the one which make screenshot with F11?
[02:18] <Yakov> i can do screen shot with F11 but it says Command 'gnome-screenshot' not found
[02:31] <guiverc> gnome-screenshot is a 'universe' package, so won't be default for 20.04 & later
[02:32] <guiverc> sorry, correction in ^... won't be default to LATER THAN 20.04
[02:33] <topcat001> Yakov: I use scrot
[02:34] <guiverc> https://releases.ubuntu.com/focal/ubuntu-20.04.6-desktop-amd64.manifest  shows it was default to 20.04, you didn't mention release Yakov
[02:42] <ahmed> Hi
[02:42] <Yakov> I have Jammy Jellyfish (what a stupid impossible to remember long name :)
[02:42] <Yakov> gnome-screenshot -a does what I want :)
[02:43] <Guest7624> WTF!
[02:44] <Guest7624> Hey there!!
[02:44] <guiverc> Yakov, most people will call it 22.04, it's codename is jammy (jellyfish is optional)
[02:44] <Yakov> I need to send something to copy buffer with xdotool or other tool, any advise?
[02:44] <Yakov> I would say 22, but not sure what 04 stands for  :)
[02:45] <Guest7624> Can someone tell me what's this?
[02:45] <Guest7624> \
[02:45] <Guest7624> \\
[02:51] <PeGaSuS> Yakov: 22.04 = April 2022 (each stable version is released on April) :)
[02:52] <Yakov> Ninja turtles praising April O Neil :)
[02:52] <Yakov> I remember now, spasibo
[02:52] <lotuspsychje> keep it ontopic please Yakov
[03:57] <Jacob78> having cpp code and string "random text", I want to call some function (C or 3rd party lib or can be Ubuntu tool) | so it would be possilbe to push Ctrl+V to paste random text | Qt Clipboard lags, xdotool can do only paste | There are might be X11 or libevdev, vendors I already use in my project, but I could not find relevant sample. Please advise
[05:12] <Terminal-V> Hi. I want to use the same UFW rules for IPv4 for IPv6. Can I copy and paste the rules from my 'user.rules' file to my 'user6.rules' file and just changed the IPv4 IP addresses to IPv6 IP addresses?
[05:15] <obiwan_> how come my ethernet connection is limited to 100/mbps?
[05:18] <Terminal-V> obiwan_ maybe because your network adapter or the device you are connected to can only do 100mbps.
[05:19] <obiwan_> Terminal-V: i don't think so because i connected the cable to my mac and i got 800+
[05:20] <Terminal-V> obiwan_ are you getting 100mbps over a wired or wireless connection?
[05:21] <obiwan_> Terminal-V: I've only tried wired so far. But I only want to use wired because I will be using it as a NAS i think
[05:22] <Terminal-V> obiwan_ what is the maximum network speed of the device you are connecting to when you only get 100mbps?
[05:23] <obiwan_> Terminal-V: well it used to be a windows machine and I got 800+ mbps as well.  Just when I turned it to ubuntu it slowed down.  Is it an issue with the OS or something else?
[05:24] <Terminal-V> obiwan_ how were you connecting to it when it was a Windows machine... wired or wireless?
[05:24] <obiwan_> Terminal-V: wired
[05:25] <Terminal-V> obiwan_ are you using the same devices to connect to each other, in the same way?
[05:25] <obiwan_> Terminal-V: yes everything the same, just the OS is diff
[05:25] <Terminal-V> obiwan_ ok. Even the same cable(s)?
[05:26] <obiwan_> Terminal-V: yes
[05:26] <Terminal-V> obiwan_ then I can't help you. Wait around.. someone who knows more about it will be here and will know.
[05:26] <obiwan_> Terminal-V: Ok thank you.
[05:27] <Terminal-V> obiwan_ all good.
[05:28] <Terminal-V> obiwan_ is your network port on your computer on the motherboard or on a card?
[05:28] <obiwan_> Terminal-V: I have no idea, it's just a laptop
[05:29] <Terminal-V> obiwan_ did you change anything in the BIOS before installing Ubuntu or reset it to factory default?
[05:30] <obiwan_> Terminal-V: I am not sure, I just selected the erase disk and install option
[05:31] <Terminal-V> obiwan_ do you require free and open source software right now? Or do you just want shit working?
[05:32] <obiwan_> Terminal-V: probably just shit working
[05:33] <Terminal-V> obiwan_ sounds reasonable. There is an additional driver app in Ubuntu. Check it out. You may need drivers to use the full speed of your network interface and they may be available.
[05:33] <obiwan_> Terminal-V: what's the name?
[05:34] <Terminal-V> obiwan_ of what?
[05:35] <obiwan_> Terminal-V: the driver app?
[05:35] <Terminal-V> Terminal its called Additional Drivers I think. It has a computer chip as an icon.
[05:36] <Terminal-V> I gotta go for lunch. Brb
[05:36] <obiwan_> Terminal-V: Ok, thanks for your help
[06:30] <katsumikougen_vn> Please help me
[06:31] <Bashing-om> !ask | katsumikougen_vn
[06:31] <katsumikougen_vn> I've got a black screen every time I turn on my ASUS laptop after hibernation
[06:32] <katsumikougen_vn> !ask
[06:35] <katsumikougen_vn> How do I fix that?
[06:39] <weedmic> size of ram and size of swap - katsumikougen_vn
[06:40] <katsumikougen_vn> weedmic: https://paste.linux.chat/?a77c799c3bccd06a#BF93Rd4GbaGWrG7cmEK8Hgo661kr9RqUq9KGs8NfSYir
[06:42] <oerheks> sometimes ctrl alt F1 and afer a fex sec, ctrl alt f2 to get gui again.
[06:42] <oerheks> hybernate issues often come from nvidia drivers and/or wifi
[06:43] <katsumikougen_vn> oerheks: 1) What is "fex sec" 2) How do I fix
[06:43] <oerheks> after a few sec(onds)
[06:43] <oerheks> i don't know any fix.
[06:57] <weedmic> I don't know if it is still true, but many years ago, you needed swap to match the amount of ram you had.  Simple enough to try by increasing your swap to match.  However, I don't general sleep machines.
[08:05] <YoGauM> hello !
[08:29] <Terminal-V> Hello. I am using Ubuntu Server 20.04 LTS. I would like to remove a repository in 'apt'. I have commented out most of the repositories in '/etc/apt/sources.list', but I don't know how to remove all of them. One one line, the ending is "main restricted". If I want to remove the restricted repository, do I just remove "restricted" from the line?
[08:31] <oerheks>  sudo add-apt-repository --remove restricted
[08:32] <oerheks> maybe some installed packages stay behind
[08:32] <oerheks> -- purge might be a help
[08:36] <Terminal-V> oerheks thanks. :) That command did the trick! :)
[08:36] <oerheks> have fun!
[08:36] <Terminal-V> oerheks would 'apt autopurge' help?
[08:37] <oerheks> autoremove* ..
[08:37] <oerheks> maybe?
[08:37] <Terminal-V> oerheks I have one thing installed, from 'main'. :)
[08:37] <oerheks> the use of --purge with that command would have removed packages too.
[08:38] <Terminal-V> oerheks sweet. I will reissue the command with the '--purge' parameter?
[08:39] <Terminal-V> oerheks I am worried it won't purge and exit once it see's the repository is already disabled.
[08:39] <Terminal-V> oerheks safe to try?
[08:40] <oerheks> try apt autoremove first
[08:40] <Terminal-V> oerheks okay. '--purge' is invalid.
[08:41] <Terminal-V> oerheks apt is not fully documented, so not your fault. :)
[08:42] <Terminal-V> oerheks everything is good now. Thanks for your help! :)
[08:42] <Terminal-V> oerheks I'll be back later. Bye for now!
[08:45] <josh_> Hi there! How are you guys doing?
[08:46] <josh_> Does anyone wanna share their thoughts on Ubuntu 22.04?
[08:48] <oerheks> hi josh_ this is technical support only, join #ubuntu-discuss for that
[08:48] <oerheks> not much going on there, atm
[08:50] <josh_> Glad to know. Well, I have an HP 14 4020 n and I am running Ubuntu 22.04, my mouse cursor randomly freezes. Any help?
[08:55] <josh_> Good morning. I have an issue with my hp 14 4020 n laptop running ubuntu 22.04, my mouse cursor randomly freezes.
[09:03] <josh_> Good morning. I have an issue with my hp 14 4020 n laptop running ubuntu 22.04, my mouse cursor randomly freezes
[09:09] <FreshRuby18> hello
[10:05] <Squatkong618> Hi all, could anyone tell me the estimated time to activate the OpenPGP keys, and become an active member of ubuntu launchpad? Thank you
[12:34] <BluesKaj> Hi all
[12:36] <andrei> is this discord
[12:53] <Terminal-V> Hi everyone. I am using OpenVPN is static key mode and having trouble connecting using AES-256-CBC. When I try, the server log says something about an authenticate/decrypt packet error cipher final failed. Does anyone know what's going on?
[12:53] <Terminal-V> And, when I connect to default authentication in Ubuntu 20.04 LTS, it works fine.
[12:54] <Terminal-V> I mean, when I connect with default cipher.
[12:56] <Terminal-V> The server is running Ubuntu 20.04 LTS. I checked the available ciphers and AES-256-CBC is there.
[12:56] <Terminal-V> Ubuntu Server 20.04 LTS
[13:02] <oerheks> aes-256-cbc is deprecated
[13:04] <Terminal-V> oerheks hi. No its not, its no under the depreciated list of available ciphers.
[13:05] <Terminal-V> oerheks its also the default negotiated cipher.
[13:06] <oerheks> yes it is.
[13:06] <Terminal-V> oerheks it is what?
[13:08] <Terminal-V> oerheks https://i.ibb.co/XFV99mz/Untitled.png
[13:08] <weedmic> andrei - no
[13:11] <oerheks>  CBC is potentially vulnerable to padding attacks, such as POODLE. GCM is not.
[13:11] <Terminal-V> oerheks maybe, but that doesn't explain my problem. :)
[13:12] <Terminal-V> oerheks also, CBC can only be used is static key mode.
[13:15] <tomreyn> Terminal-V: can you share the precise "something" the server log says when you connect? you're saying the remote (?) server runs ubuntu 20.04. what does the client / local server run?
[13:15] <tomreyn> where "what" refers to OS and openvpn version, as well as supported cipher suites.
[13:16] <Terminal-V> tomreyn I'm not going to bed. I've recently vowed I'll never let Linux keep me up all night again. Tomorrow I will provide comprehensive details, including server configuration.
[13:16] <Terminal-V> See you all around. :)
[13:16] <tomreyn> i assume that's s/not/now/, sweet dreams!
[13:36] <sem> let's say i'm using ubuntu 23.04 on a laptop/tablet thing, and I want to turn the screen off by pushing the power button
[13:36] <sem> if I search things related to that on ddg, i get all kinds of information from 8 years ago that's probably useless at best
[13:36] <sem> where to people look for modern information these days?
[13:37] <sem> also, good morning!
[13:37] <scottpedia> sem: it's such a rare name "ubuntu 23.04"
[13:38] <scottpedia> i've only heard of 22.04
[13:38] <leftyfb> !lunar | scottpedia
[13:38] <scottpedia> ok interesting
[13:38] <leftyfb> sem: there's no GUI option for that. You might be able to capture the button press and write your own script to lock the machine
[13:38] <scottpedia> i really haven't followed up on that recently
[13:39] <scottpedia> is it an LTS leftyfb ?
[13:39] <ravage> https://manpages.ubuntu.com/manpages/trusty/man5/logind.conf.5.html -> HandlePowerKey
[13:39] <leftyfb> scottpedia: no
[13:39] <ravage> maybe that is useful?
[13:40] <ravage> or maybe https://manpages.ubuntu.com/manpages/lunar/man5/logind.conf.5.html . but i dont think a lot has changed
[13:40] <leftyfb> sem: https://superuser.com/a/1523940
[13:41] <scottpedia> can you help me look up the EOL date for 23.04? leftyfb
[13:41] <leftyfb> scottpedia: type this into google.com "ubuntu 23.04 eol"
[13:42] <ravage> https://wiki.ubuntu.com/Releases
[13:42] <scottpedia> Jan 2024???
[13:42] <scottpedia> that's short-lived
[13:42] <ravage> you passed the reading test
[13:42] <tomreyn> !lts | scottpedia
[13:42] <sem> Thanks :)
[13:43] <tomreyn> !yy.mm
[13:44] <scottpedia> so .04 means it's released in April
[13:44] <sem> it's nice that linux gives you the tools to do all these custom things, but at the cost of making your system really complex :p
[13:44] <tomreyn> hmm i was looking for the one wich says only even years are lts, but then that's not guaranteed.
[13:44] <tomreyn> scottpedia: correct.
[13:45] <tomreyn> at least at this position.
[14:04] <Beladona40> which postgres version is supported in LTS?
[14:05] <ravage> !jammy postgres
[14:05] <oerheks> !info postgres jammy
[14:05] <ravage> i always forget it
[14:05] <oerheks> https://packages.ubuntu.com/jammy/postgresql
[14:05] <ravage> !info postgresql jammy
[14:05] <Beladona40> why not v15?
[14:06] <leftyfb> !latest | Beladona40
[14:06] <oerheks> because LTS
[14:06] <oerheks> no newer functions, only bugfixes
[14:06] <ravage> lunar has 15. but i would not recommend that as a server
[14:06] <Beladona40> freebsd has v15... debian has v15, why not ubuntu LTS? are the formar less table and less long term support than ubuntu LTS?
[14:07] <Beladona40> ravage lunar?
[14:07] <leftyfb> Beladona40: please seek support with freebsd and debian in their respective channels. This is for Ubuntu support
[14:08] <Beladona40> leftyfb I am comparing. Not asking for the other OS
[14:08] <Beladona40> leftyfb I am asking the reasons for v14 in UBUNTU
[14:08] <leftyfb> Beladona40: to answer your queston an even simpler way, Postgresql was released October 2022. Ubuntu 22.04 was released April 2022
[14:08] <Beladona40> so no upgrades available in ubuntu lts?
[14:08] <leftyfb> !latest | Beladona40
[14:09] <Beladona40> ok , so no upgrades available in ubuntu lts?
[14:09] <oerheks> nope, or find a PPA. use at your own risk.
[14:10] <leftyfb> Beladona40: Postgresql in Ubuntu 22.04 is fully patches for all security updated and major bugs
[14:10] <leftyfb> updates*
[14:10] <Beladona40> not for apps upgraded versions?
[14:10] <leftyfb> no
[14:10] <Beladona40> ok.
[14:14] <Beladona40> so just to understand ubuntu LTS != debian stability / concept?
[14:14] <oerheks> have fun!
[14:15] <leftyfb> Beladona40: https://unix.stackexchange.com/a/28448
[14:16] <leftyfb> Beladona40: https://wiki.ubuntu.com/DebianImportFreeze
[14:18] <oerheks> postgreSQl itself says the same, but if you *need* v15, use their repo, again at your own risk, not supported by the community https://www.postgresql.org/download/linux/ubuntu/
[14:20] <Beladona40> so almost both ubunt LTS and debian are kind of equal in stability?
[14:23] <oerheks> Ubuntu is always better, no?
[14:25] <Beladona40> how?
[16:03] <JPZone> Hello I am trying to install python on a Ubuntu server and getting the following error. "dpkg: error processing package python3-setuptools (--configure):

[16:03] <JPZone>  python3
[16:05] <JPZone61> Hello
[16:05] <JPZone61> I am trying to install Python onto a Ubuntu server and getting the following error any ideas? https://dpaste.com/EVZTZNQLP
[16:16] <rbox> what do you mean "trying to install python"... python is always installed
[16:18] <JPZone61> rbox no its not did python --version and nothing pops up
[16:18] <rbox> what version of ubuntu
[16:21] <JPZone61> Ubuntu 20.04.6 LTS
[16:24] <rbox> to run python you need to use the python3 command
[16:24] <rbox> to isntall the python compataiblity link you need to install the python-is-python3 package
[16:26] <JPZone61> But when i do "sudo apt-get install python3" it doesnt work...
[16:26] <rbox> a normal ubuntu install already has python
[16:26] <rbox> i dunno what you've done to break it
[16:27] <JPZone61> hmm got ubuntu, added docker and never touched python
[16:28] <shadow255> JPZone61: does python --version actually produce no output?
[16:29] <JPZone61> shadow255 i get bash: python: command not found
[16:29] <shadow255> JPZone61: how about /usr/bin/python3 --version
[16:30] <JPZone61> @shad
[16:30] <JPZone61> @shadow255 there is no directory
[16:32] <shadow255> JPZone61: surely there must be a /usr/bin directory; otherwise there would be massive problems
[16:32] <JPZone61> shadow255  oh there /usr/bin  just no python
[16:32] <shadow255> I specified python3
[16:33] <JPZone61> sorry i mean there is no Python3 directory
[16:33] <shadow255> not a directory, just a file
[16:33] <shadow255> well it sounds like you have a mess that I can't help with
[16:34] <JPZone61> in /usr/bin there is nothing related to Python
[16:37] <amir123> q
[16:37] <amir123> Hi there
[16:38] <amir123> q
[16:58] <elias_a> JPZone61: What does python3 --version say?
[17:06] <jhutchins> JPZone: Have you tried "locate python"?
[17:06] <jhutchins> JPZone: Have you looked at your shel environment variables to see if there's a path for python?
[17:07] <jhutchins> JPZone: It's usually set up off of the main executable path so that you can have multiple versions and just switch environments.
[17:07] <jhutchins> Java does this too.
[17:44] <RifftE> I'm stuck with 20.04 for the time being, are there any gotchas to security updates compared to 22.04?
[17:45] <rbox> "gotchas"?
[17:45] <ravage> not really. standard support ends in April 2025
[17:46] <RifftE> Just wanted to know if there was any strings attached to using an older ubuntu rbox. Isn't ubuntu pro free for one user?
[17:46] <ravage> !pro | RifftE
[17:50] <RifftE> I'll give ubuntu pro a try. Thank you.
[18:19] <Beladona90> The space is there but maybe small /boot partition. how can I fix?
[18:19] <Beladona90> https://pastebin.mozilla.org/jY5eC6TP
[18:21] <rbox> you can try removing some old kernels
[18:22] <Beladona90> rbox what commadn?
[18:22] <rbox> you use apt to remove packages...
[18:22] <wearethelifers> sudo apt list --installed
[18:22] <Beladona90> sudo apt purge  initrd.img-6.2.0-26-generic
[18:22] <Beladona90> E: Unable to locate package initrd.img-6.2.0-26-generic
[18:22] <Beladona90> E: Couldn't find any package by glob 'initrd.img-6.2.0-26-generic'
[18:22] <wearethelifers> check for installed kernels
[18:24] <Beladona90> wearethelifers how exactly. I am new at this
[18:24] <wearethelifers> just open your terminal of choice then
[18:24] <wearethelifers> sudo apt list --installed
[18:24] <Beladona90> lista lot of things
[18:27] <Beladona90> fixed https://www.cyberciti.biz/faq/ubuntu-18-04-remove-all-unused-old-kernels/
[18:32] <Guest123412> hello
[18:33] <wearethelifers> hi!
[18:33] <Guest123412> i have messed up my system, i cant start a new gui program
[18:33] <wearethelifers> :o
[18:33] <wearethelifers> execute dmesg and check for any errors
[18:34] <Guest123412> ever the message 'symbol lookup error: /lib/x86_64-linux-gnu/libQt5Core.so.5: undefined symbol: g_main_context_push_thread_default'
[18:34] <rbox> what did you do to get into this situation
[18:34] <Beladona90> nothing
[18:34] <Beladona90> fresh install. in vbox
[18:35] <elapagon> messed up libpath? missing libs?
[18:35] <rbox> you said you messed it up
[18:35] <rbox> it doesnt come pre messed up
[18:36] <Beladona90> not sure if installing some apps messed it up or not
[18:36] <Beladona90> but those were simple apps like git
[18:37] <Beladona90> update, upgrate
[18:37] <rbox> installing git isn't going to break qt
[18:37] <Beladona90> the /boot is small. <-- ubuntu partition issue at setup.
[18:37] <Beladona90> it auto sizes boot
[18:37] <Beladona90> you can file a bug
[18:37] <rbox> oh wait, are there 2 people talking?
[18:38] <Guest123412> but xterm still starts
[18:38] <rbox> xterm doesnt use qt
[18:39] <Guest123412> uses qt gtk?
[18:39] <Eickmeyer> Neither
[18:40] <Guest123412> what uses xterm?
[18:40] <Eickmeyer> xterm makes direct calls to x11
[18:41] <Guest123412> how can i fix undefined symbol: g_strcmp0 ?
[18:41] <Eickmeyer> *you* don't. That's probably only a warning and not an error, in which case it can be safely ignored.
[18:42] <rbox> [11:34:15 AM] <rbox> what did you do to get into this situation
[18:42] <elapagon> Guest123412, use ldd /path/to/executable, chech what files it can't find
[18:45] <Guest123412> what is a minimal file manager?
[18:45] <Guest123412> graphical
[18:46] <wearethelifers> PCManFM
[18:47] <Guest123412> dont start, needs libgio-2.0.so.0
[18:47] <wearethelifers> hmm
[18:47] <Guest123412> but why it can't be loaded?
[18:47] <wearethelifers> open a terminal emulator
[18:48] <wearethelifers> apt install libglib2.0-dev
[18:49] <Guest123412> Fehler traten auf beim Bearbeiten von: desktop-file-utils
[18:50] <Guest123412> outputs only: /usr/bin/gdbus: symbol lookup error: /lib/x86_64-linux-gnu/libgio-2.0.so.0: undefined symbol: g_sequence_free
[18:50] <Guest123412> can i use apt without libgio?
[18:52] <Eickmeyer> This looks like it would be best fixed by a reinstall. Something happened that totally trashed your system.
[18:52] <wearethelifers> it doesn't **just** happen
[18:52] <Eickmeyer> wearethelifers: They said they did something that trashed it.
[18:53] <Eickmeyer> But, the question is, which would take more time? Figuring it out or reinstalling?
[18:53] <rbox> still hasn't said what they did
[18:53] <Eickmeyer> ^
[18:53] <rbox> so it was obsvlusy something stu[pid
[18:53] <lotuspsychje> maybe recoverymode can help?
[18:53] <Eickmeyer> rbox: Obviously, but no need to insult. :)
[18:54] <rbox> i dindt say he was stupid
[18:54] <rbox> i said he did something stupid
[18:54] <Eickmeyer> rbox: I understand that, but it's still tantamount to insult.
[18:54] <elapagon> I remember installing slackware some time in 1996, went for months without X because I couldn't get Xfree86 to start
[18:54] <Eickmeyer> elapagon: Let's stay on topic, please.
[18:56] <Beladona91> https://pastebin.mozilla.org/qRmd97if  apps say no space left. its a 20gb vbox
[18:57] <wearethelifers> 921mb left on mountpoint "/" and 496mb left on mountpoint "/dev/sda2"
[18:58] <wearethelifers> that surely isn't much free space left
[19:03] <elias_a> sudo apt clean
[19:03] <Beladona91> ok
[19:03] <elias_a> It does not solve the problem with the virtual machine, though.
[19:05] <elias_a> B
[19:06] <akik> moi elias_a
[19:08] <akik> elias_a: do you have some issue with a vm?
[19:10] <elias_a> akik: No.
[19:12] <elias_a> I also misread what Beladona91 wrote.
[19:59] <[Luca]> hi there . i want to know how can i add iptables -I INPUT -s 0.0.0.0/0 -j ACCEPT on the server so that i don`t need to put this command every time after reboot to access http
[20:00] <rbox> just disable ufw
[20:00] <[Luca]> it`s the only way ?
[20:01] <rbox> what do you mean "only way"
[20:01] <rbox> it sounds like you dont want a firewall...
[20:01] <[Luca]> so this command is that is all about ?
[20:02] <rbox> what?
[20:02] <[Luca]> iptables ...
[20:02] <[Luca]> it`s just like disabling ufw
[20:02] <[Luca]> ?
[20:03] <rbox> no
[20:03] <[Luca]> i want to understand
[20:03] <rbox> understand what
[20:03] <[Luca]> if i reboot the server i need to put this command
[20:04] <rbox> yeas
[20:04] <rbox> because ufw enables firewall rules
[20:04] <[Luca]> to access http or znc or something else
[20:04] <[Luca]> got it
[20:04] <[Luca]> can i add this command somewhere to run after reboot
[20:05] <rbox> [01:00:01 PM] <rbox> just disable ufw
[20:05] <[Luca]> or is the same thing if i disabled ufw
[20:05] <rbox> its not the same thing
[20:05] <[Luca]> ok
[20:05] <rbox> but disabling a firewall or allowing all connectison from anywhere is a very bad idea
[20:06] <[Luca]> got it
[20:07] <[Luca]> tnx rbox for help
[20:13] <gordonjcp> meh, firewalls are such a Windows-y thign
[20:13] <gordonjcp> *thing
[20:14] <rbox> has nothingt o do with windows...
[20:14] <gordonjcp> at work IT security policy requires firewalls on everything
[20:14] <gordonjcp> not sure what advantage they're supposed to convey on Linux though
[20:14] <rbox> as thety shoulkd be
[20:14] <gordonjcp> total waste of time
[20:14] <rbox> riofl
[20:14] <gordonjcp> idiotic
[20:15] <rbox> somethign in this conversation is idiotic... thats for sure
[20:15] <gordonjcp> rbox: okay, then
[20:15] <gordonjcp> rbox: what's the advantage?
[20:16] <gordonjcp> what would having a firewall on a Linux server do?
[20:17] <rbox> the same thing it does on any computer
[20:17] <gordonjcp> which is?
[20:18] <rbox> https://en.wikipedia.org/wiki/Firewall_(computing)
[20:18] <gordonjcp> I know what it is, and the wikipedia definition isn't really that good
[20:18] <causative> it closes ports so an adversary can't exploit vulnerabilities in applications on the computer
[20:18] <gordonjcp> rbox: can you clearly and lucidly explain what advantage it would have?
[20:18] <gordonjcp> causative: okay, but you don't need to do that
[20:19] <rbox> dont need to? rofl
[20:19] <gordonjcp> causative: you can just not run things on those ports
[20:19] <rbox> and if you ARE running somethign...
[20:19] <rbox> or you want to restrict WHO can use it
[20:19] <gordonjcp> then you configure your application correctly
[20:19] <rbox> ROFL
[20:19] <gordonjcp> rbox: here, have a crack at this
[20:19]  * rbox ignores the morons
[20:19] <gordonjcp> rbox: gjcp.net is a real physical server, one of several that I run
[20:20] <gordonjcp> rbox: it runs Ubuntu 20.04
[20:20] <causative> it's easier and more foolproof to set up a firewall to block all but ports X Y Z, than it is to ensure that every single application running on the computer is not using any other ports
[20:20] <gordonjcp> rbox: it has no firewall
[20:20] <gordonjcp> rbox: deface *any* website running on it
[20:20] <gordonjcp> rbox: here, the root password is Prich]swyong5
[20:20] <gordonjcp> rbox: have at it
[20:21] <gordonjcp> come back when you've defaced at least one site it serves
[20:21] <gordonjcp> literally gave you the keys to the kingdom there
[20:22] <gordonjcp> awww, is it not working?
[20:23] <gordonjcp> I'm guessing the APNIC one is just normal Chinese government poking
[20:23] <akik> gordonjcp: try learning about firewalls first before saying things like that
[20:23] <causative> the firewall can be configured to do that in *one* place, and to make sure every single application isn't doing it means you have to look in *many* places and read the documentation of many different programs and make sure none of them have undocumented behavior
[20:24] <oerheks> please, stay ontopic, thanks
[20:24] <gordonjcp> akik: I know a lot about firewalls
[20:24] <akik> gordonjcp: doesn't sound like it
[20:24] <gordonjcp> akik: I just don't see the advantage in systems that can be locked down by default, and configured sensibly
[20:25] <gordonjcp> akik: okay, well, you can have a shot at getting into a non-firewalled machine too
[20:25] <gordonjcp> akik: it's hard to pick out who's just recently started with all the login attempts from Russia and China, I will say
[20:25] <akik> gordonjcp: here's an example; your users can start up daemons on high ports and they're accessible if you haven't blocked them with iptables
[20:27] <akik> gordonjcp: another example; you can keep sshd safely open on port 22 and then just filter it with the ip addresses that need access to it
[20:28] <akik> i did that for my landline isp's networks, blocked everything else
[20:28] <gordonjcp> akik: okay, but letting randoms start services is a problem generally
[20:28] <akik> that's my $0.02. good luck
[20:28] <gordonjcp> akik: I'll grant you that is a viable use case, but I'd rather just drop traffic at the border router
[20:29] <gordonjcp> akik: re ssh, you can just configure sshd to do that, as the various "enthusiastic amateurs" in Russia are slowly figuring out
[20:37] <jhutchins> The problem with filtering ssh by ip address is that the system still has to deal with every packet of the attacks.  If you move ssh to a random port (not 222) you don't get the traffic in the first place.
[20:37] <leftyfb> !ot | gordonjcp
[20:37] <gordonjcp> jhutchins: security by obscurity, but it sure does help
[20:37] <leftyfb> gordonjcp: also, don't encourage unauthorized access in any manner.
[20:38] <gordonjcp> leftyfb: this is entirely authorised
[20:38] <leftyfb> gordonjcp: this conversation belongs in #security
[20:38] <gordonjcp> yeah, probably
[20:38] <gordonjcp> I'll just eat my popcorn and watch auth.log
[20:38] <leftyfb> gordonjcp: I guarantee if you present that same challenge there, you won't be happy
[20:40] <tomreyn> gordonjcp: please chat about it elsewhere, though. this channel is for support, not for prove-me-wrong type discussions.
[20:40] <loswedseded> what could explain that thunar needs a second to react to my mouse prompts
[20:40] <loswedseded> ?
[20:41] <oerheks> and, why is that slow?
[20:43] <loswedseded> it usually reacts instantly
[20:43] <loswedseded> like click and the files gets marked
[20:44] <tomreyn> loswedseded: would oyu know when this started to be slow? what else may have happened when this started?
[20:44] <loswedseded> actually 10 minutes ago, I believe after I mkvtoolnixed a file
[20:45] <oerheks> i sell my bed
[20:45] <loswedseded> I also installed android studio and that needed 13 GiB of space, but I don't see any correlation
[20:45] <tomreyn> loswedseded: maybe this process is still running and you have a high system load?
[20:47] <loswedseded> ill check htop I guess
[20:47] <tomreyn> what's the current cpu load, how much free and total RAM do you have? how much free disk space on your ubuntu related file systems ?
[20:47] <loswedseded> but I believe my system is a bit unsttable since I tried flash roms into 2 phones...
[20:48] <tomreyn> unless this means you installed software from unreliable sources this would not cause ubuntu to become unstable
[20:48] <tomreyn> (or changed critical system configurations)
[20:51] <loswedseded> nope
[20:52] <loswedseded> either my machine is too old to play x265 and it reacts like this or I should unmount disk images after Im done with them, but this never happened before: I used to leave iso images mounted for hours. This was never a problem
[22:41] <jhutchins> louisa: How would transferring data to a ROM affect your system, unless it was the system cmos rom?
[22:50] <hay207> Hi guys
[22:51] <hay207> I want development of UFO alien invasion to continue
[22:51] <hay207> I wonder if ubuntu team can help
[22:51] <hay207> it is an open-source game
[22:54] <hay207> Very good turn-based game like Xcom
[22:55] <jeremy31> hay207: I doubt many people that could help are here
[22:55] <hay207> I hope ubuntu picks it up?
[22:58] <tomreyn> there are "ufoai" packages in most supported ubuntu versions. i can understand and share the desire to see continued development on this game. but this channel is not really a good place to bring this up. we mostly do self-support for using (not even developing) ubuntu here.
[23:03] <hay207> i don't know any other good channel to ask for help
[23:03] <NickH> https://ufoai.org/wiki/Contact
[23:04] <tomreyn> https://forum.freegamedev.net/ may be a good place to bring it up
[23:05] <tomreyn> (that's if you're hoping to contribute)
[23:07] <hay207> Nice forum
[23:08] <hay207> I can try asking there
[23:13] <hay207> Thanks, bye
