| YokoBR | hi guys | 01:05 |
|---|---|---|
| YokoBR | As I have only one NIC, i've created two virtual interfaces. Now the three interfaces has 255.255.0.0 as masks and created dhcp configs with 3 ranges, 192.168.0.2-254, 192.168.1.2-254 and 192.168.2.2-254 | 01:05 |
| YokoBR | would that work? | 01:06 |
| sarnold | YokoBR: it may not work with that netmask.. | 02:01 |
| sarnold | YokoBR: try instead 255.255.255.0 and install explicit routes for all three networks to the other two networks. | 02:01 |
| YokoBR | sarnold: i think the problem was solved. | 02:02 |
| YokoBR | this is what i did, 10.100.0.1 255.255.252.0. DHCP range 10.100.0.1 - 10.100.3.254 | 02:02 |
| sarnold | that sounds like it should work, yeah | 02:02 |

| showaz | Hello, how to reset a Ubuntu-Server 16.04 initial state before install "apt remove ... --purge --auto-remove" (ubuntu-minimal). | 09:58 |
| rbasak | showaz: "apt-get install ubuntu-minimal^" perhaps? | 10:00 |
| rbasak | (or is it "minimal^"? | 10:00 |
| rbasak | ) | 10:00 |
| showaz | ubuntu-minimal already installed. | 10:01 |
| rbasak | Well then I don't understand your question. | 10:01 |
| showaz | rbasak: To restore ubuntu-server to original appearance after you install a hosting panel (packages/user-data purge) | 10:04 |
| rbasak | showaz: well that depends on what your hosting panel installer did. Your hosting panel provider needs to answer your question really. | 10:04 |
| rbasak | It might be easier just to reinstall your server or restore from backup or whatever. I certainly wouldn't continue using a production server after messing around with it like that. | 10:05 |

| rharper | rbasak: I'll look at that today | 12:32 |
| rbasak | rharper: thanks! | 12:36 |
| rharper | rbasak: to be clear, both the load file and the so should be removed since we're disabling support of http2 | 12:36 |
| rbasak | rharper: I'm not sure. I don't mind what is removed so long as nothing explodes. I suspect the load file being there might be a problem, so I thought it probably warrants investigation. | 12:37 |
| rbasak | rharper: it may be that you're satisfied that nothing needs doing after looking. | 12:37 |
| rharper | ok; but the goal is for http2 to not be enabled by default | 12:37 |
| rharper | and things shouldn't break | 12:37 |
| rbasak | Right. | 12:37 |
| rharper | ok | 12:37 |
| rbasak | rharper: actually not just not enabled by default but not built. | 12:38 |
| rbasak | Until the security team says it's OK, which I don't think they will until upstream no longer consider it experimental. | 12:38 |
| rharper | rbasak: ok; then I wouldn't suppose we should ship any http2 files either (if we don't bother building it) no ? | 12:49 |
| rbasak | rharper: that would be sensible, yes. But if it's not actually causing a problem, it's probably not worth breaking final freeze for that. | 12:50 |

| devster31 | I have a pretty minimal ubuntu install, is there a cli utility that allows me to interact with dhcp client and servers? I want to read the information the server is broadcasting | 13:18 |
| hateball | devster31: other than dhclient ? | 13:21 |
| devster31 | I thought dhclient was used to configure an interface, I just want to read the information | 13:23 |

| rbasak | rharper: I think you're right in that the conffile needs that handling to remove. | 16:22 |
| rbasak | rharper: I don't see anything wrong with your conffile handling, but a couple of things to make it simpler: | 16:23 |
| rbasak | 1) you don't need to make it conditional on $1; dpkg-maintscript-helper takes care of that itself. | 16:23 |
| rharper | which did I make a conditional ? | 16:24 |
| rbasak | 2) you can use debian/apache2.maintscript to save having to touch all the maintainer scripts. Then debhelper will take care of it. | 16:24 |
| rbasak | You're calling remove_http2_conffile from inside the switch statement | 16:24 |
| rbasak | Which could well be absolutely correct but I'd need to check. | 16:24 |
| rharper | ah, I see | 16:24 |
| rharper | there are stage checks in mainscript itself | 16:25 |
| rharper | lemme look at the apache2.maintscript then | 16:25 |
| * rharper missed that | 16:25 | |
| rbasak | rharper: see the dh_installdeb manpage. | 16:25 |
| rbasak | You couldn't know about it unless you already did :-/ | 16:25 |
| rharper | heh | 16:25 |
| rharper | yeah | 16:25 |
| rharper | that's fancy sauce right there | 16:25 |
| rbasak | Basically you put the dpkg-maintscript-helper calls in there and then debhelper takes care of it. | 16:25 |
| rbasak | But good job in spotting that you needed conffile handling :) | 16:26 |
| rharper | though one still has to debug the prior version stuff | 16:26 |
| rharper | rbasak: slangasek helped me see that in squid | 16:26 |
| rbasak | rharper: squid's conffile handling was painful! | 16:31 |
| rharper | to say the least | 16:32 |
| rbasak | rharper: btw, did you figure out if having http2.load present actually causes a problem? | 16:32 |
| rharper | let me test that out | 16:32 |
| rharper | I imagine it'll throw an error but unlikely to cause problems; I think apache2 handles missing modules gracefully | 16:32 |
| rharper | no | 16:33 |
| rharper | well, it just wont start, if you a2enmod http2 and then restart, apache2 won't start | 16:33 |
| rharper | yeah | 16:34 |
| rharper | so better to remove the file | 16:34 |
| rharper | no one get's hurt accidentally (it's in mod-avail, not mod-enable) | 16:34 |
| rbasak | OK, thanks for checking. | 16:35 |
| rharper | but if someone did attempt to enable it and restart apache, it fails due to the missing so file we removed | 16:35 |
| rharper | nice, that apache2.maintscript is very cool | 16:36 |
| * rharper attaches a new debdiff | 16:36 | |
| rbasak | rharper: the new debdiff looks good, thanks. Have you tested that this works, please? | 16:48 |
| rbasak | rharper: I'd also note in the changelog that it was inadvertently dropped in an intermediary merge just to make the next merger's life easier in figuring out the logical delta. I can note that when uploading, no need for a new debdiff. | 16:48 |
| rharper | rbasak: yes; I've tested the same upgrade and the file is removed properly | 17:11 |
| rbasak | rharper: OK, thanks. Do you think this should break final freeze or should we aim for a 0-day SRU? | 17:12 |
| rharper | rbasak: sorry about not mentioning *why*; I know better =( | 17:12 |
| rharper | I think 0day is fine | 17:12 |
| rbasak | OK | 17:12 |
| rharper | it's out of the way | 17:12 |
| rharper | unless someone is explicitly doing a2enmod http2 | 17:12 |
| rbasak | That would always break at some point, right? | 17:13 |
| rbasak | Either in the a2enmod command, or with this bug on apache2 restart. | 17:13 |
| rharper | right | 17:13 |
| rbasak | So they shouldn't be doing it and expect it to work presumably :) | 17:13 |
| rbasak | Then I think a 0-day is fine. | 17:13 |
| rharper | they might expect it due to the version, and http2 is enabled in debian | 17:13 |
| rharper | but | 17:13 |
| rharper | it's noted in the changelog why we don't have it enabled at this point | 17:14 |

| aeronavi | how to create a pty without an attached process? | 18:16 |
| aeronavi | my idea is to open terminal window, where I can later attach a process with redirected standard input/output and then control it from that window | 18:19 |
| sarnold | aeronavi: sounds like you're re-inventing screen or tmux | 18:20 |
| sarnold | fwiw I haven't seen "terminal without a process" in a while -- back in those days of course we had serial cards in our computer with 16 or 32 serial ports, and flat phone-wire run throughout the building for the terminals.. | 18:21 |
| RoyK | screen is really cutting edge - I mean - it came out in 1987 | 18:22 |
| sarnold | gotta keep up with these new tools :) | 18:22 |
| RoyK | :D | 18:22 |
| patdk-wk | royk, it should be replaced, it's old and single purpose like init | 18:23 |
| patdk-wk | maybe we need a screend | 18:23 |
| RoyK | tmux is better | 18:23 |
| aeronavi | hehe sarnold, im not from that time. | 18:24 |
| RoyK | aeronavi: well, it's been used steadily over those almost 30 years | 18:24 |
| RoyK | I guess 'ls' is a wee bit older | 18:25 |
| RoyK | but people are still using it!!!!!!!!!!!!! | 18:25 |
| aeronavi | but screen must spwan always a process right? | 18:27 |
| arooni | why when i login to my server do i see 56 packages can be updated? i thought i had security updates automatically installed. must i do a separate setup for regular updates to packages? and more importantly, is this advised? | 18:28 |
| RoyK | aeronavi: nah - you can have several - just use tmux if you aren't used to screen - it's Newer And Better (tm) | 18:28 |
| === tinwood_afk is now known as tinwood | ||
| aeronavi | spawn* . I plan to debug a process with gdb that is called inside a script, but i would like to control gdb on a external window | 18:30 |
| teward | arooni: updates != security updates | 18:30 |
| teward | arooni: it's possible to have a lot of non-security updates pending in the -updates repo for your computer, but they won't get installed if you only put on security updates | 18:30 |
| arooni | teward is setting up auto updates of non security updates possible? and advised? | 18:31 |
| RoyK | arooni: I'm using all sort of updates on my machines - haven't failed so far (over the years) | 18:35 |
| RoyK | last issue we had at work, was today, a new samba version came out of redhat's repos and suddenly kerberos was needed for everything, and that was a security update | 18:36 |
| RoyK | broke a few clients not in AD | 18:36 |
| aeronavi | RoyK when i start tmux or screen, it spawn a shell process. | 18:40 |
| aeronavi | is it possible to just start it without any process? | 18:41 |
| sarnold | why? | 18:45 |
| aeronavi | so later I can redirect input/output of other processes | 18:48 |
| aeronavi | and control there | 18:49 |
| sarnold | why not just start that other process in screen? | 18:51 |
| aeronavi | sarnold because the process in question is called from inside a script | 18:57 |
| arooni | i'm trying to access /var/log/nginx ; but i'm getting access denied because my ssh user isn't part of the adm group. so i did; sudo usermod -a -G adm myuser; but i still cannot access.. :\ why not? | 19:08 |

| RoyK | mhm | 20:45 |
| qman__ | I've had release upgrades break plenty of stuff but not regular patches | 20:46 |
| RoyK | it was a bit fancy this security update by redhat | 20:47 |
| keithzg | I tend to have it only on for security updates, but that's almost more just because I feel like giving myself something to do from time to time ;) | 20:47 |
| RoyK | suddenly everything not in the AD was banished | 20:47 |
| sarnold | RoyK: in all fairness there's a half-way tolerable chance the same thing will happen with our samba updates next week | 20:48 |
| RoyK | I gues so | 20:48 |
| RoyK | guess, even | 20:48 |
| sarnold | RoyK: the only feedback we've gotten so far has been good but samba is so bloody configurable.. | 20:48 |
| RoyK | sarnold: we found two solutions - either login with ad-domain@user, or install winbind | 20:49 |
| RoyK | I didn't try the former - we just went for winbind | 20:49 |
| RoyK | we've got some 25k users, so these things hurt a bit when that little percentage of them not using windows lose access to their data | 20:50 |
| sarnold | even 0.1% is a noticable amount of work :) | 20:51 |
