[17:36] <brunipc> Hello, is there anything that I should definitely install or disable after installation to improve the security of my system?
[17:36] <brunipc> installing 18.04 right now
[17:37] <diogenes_> gufw
[17:37] <tomreyn> not neccessarily.
[17:39] <tomreyn> brunipc: by default, unlike other OS, ubuntu has no services listen on the network. but surely you may install such packages and then you should take measures to prevent access to them by unauthorized folks (and moreover bots) from the internet
[17:40] <brunipc> I remember a couple years ago (last time I used Linux) there used to be I think a print server running by default
[17:41] <Spass[m]> brunipc: hello, some Firefox extensions blocking tracking cookies/scripts and ads, but that's not OS-specific of course
[17:41] <brunipc> hi.
[17:42] <brunipc> ok, thanks a lot.
[17:42] <Spass[m]> but yeah, Gufw if you want simple firewall, ClamTk (AV) if you share your data with many Windows machines (on USB stick for example)
[17:43] <brunipc> in general, if there are no services running (and I don't intend to change that) do I need a firewall?
[17:43] <brunipc> no services listening on the network I mean
[17:45] <tomreyn> i just tried to verify what i said, and i may have spoken wrong there
[17:46] <tomreyn> dhclient, dnsmasq, cups, avahi-daemon are listening on udp ports bound to 0.0.0.0 here
[17:46] <tomreyn> but then this is not a freshinstallation
[17:46] <brunipc> cups, that's the thing I remember
[17:46] <tomreyn> cups-browsed specifically
[17:47] <tomreyn> the service which looks for printers on the web (and receives their broadcasts)
[17:47] <tomreyn> or was it the web interface?
[17:47] <tomreyn> sorry, i should get my facts straight
[17:47] <brunipc> no, thanks for answering my questions
[17:47] <tomreyn>        cups-browsed - A daemon for browsing the Bonjour broadcasts of shared, remote CUPS printers
[17:47] <diogenes_> brunipc, one more thing, very important one, if you experience low internet speed, change your dns to either google one or cloudflare, i prefer quad9.
[17:48] <brunipc> ok, will do
[17:49] <tomreyn> also if you cannot reach some websites because your ISP blocks / redirect them
[17:49] <tomreyn> i think t-online also does domain name typo redirects via dns
[17:50] <tomreyn> https://de.wikipedia.org/wiki/Typosquatting
[17:51] <brunipc> how to i change dns to quad9?
[17:51] <tomreyn> you set their nameservers on your connection profile
[17:52] <diogenes_> brunipc, after the installation is done, reboot and come back here, we will guide you through.
[17:52] <brunipc> alright, thank you so much
[17:53] <brunipc> I'm installing on top of 14.04 i had on an old dvd and it'll be another 8 minutes for whatever is being downloaded
[17:55] <tomreyn> !14.04
[17:56] <tomreyn> in fact, xubuntu was only supported until april 2017, i think
[17:59] <brunipc> yes I'm installing 18.04 right now
[18:00] <brunipc> which to me relief accepts my fritz wlan usb card no questions asked
[18:01] <tomreyn> glad it works, sorry to hear you depend on such.
[18:02] <brunipc> It's my mom's PC.
[18:03] <brunipc> the specs seemed decent for $300 dollar, but it's a gaming pc kinda deal so I guess they assumed gamers use ethernet and they could save a couple bucks
[18:06] <brunipc> ok, i'll reboot now, thank you so much for your help
[18:10] <tomreyn> yw
[20:46] <xubuntu51w> Is it possible to use a USB Huawei mobile broadband modem on Xubuntu ? Can it just be plugged in and will be ready to use or what ?
[20:52] <diogenes_> xubuntu51w, i'm using one right now, you plug it in, wait like for a minute then click on the network icon and choose new mobile broadband connection and just follow the steps, that's it.
[20:53] <xubuntu51w> It sounds good. I understand it was more complicated on older versions on Xubuntu/linux.
[20:54] <diogenes_> i never had any issues with it.
[20:56] <tomreyn> it can depend on the very modem, i guess? i imagine some just won't work at all.
[20:57] <diogenes_> huawai works, some rtl might be troublesome.
[20:58] <xubuntu51w> I hear the system before tought it was a USB memory only and som fixes was needed to use the modem.
