| gasconheart | I run Ubuntu Server on a regular PC, I've been running it for months or perhaps more than one year. Recently it crashed seemingly on its own, twice, one 24h after the other | 10:57 |
|---|---|---|
| gasconheart | it crashed and froze, it went unresponsive, I had to take this photograph: http://www.gasconheart.cu.cc/crashscreenshot/ | 10:57 |
| gasconheart | I need some help understanding those messages; thank you very much | 10:58 |
| ikonia | gasconheart: so thats a kernel panic | 11:03 |
| ikonia | thats the stack trace from the panic, the bit on screen is showing the filesystem details in memory | 11:04 |
| taliptako | Hello | 11:32 |
| taliptako | why shouldnt i manage my server from root account ? | 11:32 |
| RoyK | well, obviously, you can | 11:33 |
| RoyK | but it's more common to use sudo these days to allow for logging who did what | 11:33 |
| RoyK | also, allowing ssh logins to root, especially with password authentication isn't really a good idea - should work well with keys, though | 11:34 |
| taliptako | actually i just have LEMP stack on my Ubuntu 16.04 server and i intalled those software as a root | 11:35 |
| ikonia | "E" ? | 11:35 |
| taliptako | now i had little problem about file permissions | 11:35 |
| ikonia | if you installed them using the package manager, the permisions should be fine out of the box | 11:35 |
| taliptako | i wonder if this cause because i installed all softwares as a root account | 11:35 |
| ikonia | taliptako: did you install using the ubuntu package manager ? | 11:36 |
| taliptako | of course i installed with apt | 11:36 |
| ikonia | then the only way to use that is with root privileges | 11:36 |
| ikonia | so how can that be the problem ? | 11:36 |
| taliptako | but maybe its different to do things from root account or with sudo | 11:36 |
| taliptako | i dont know | 11:36 |
| ikonia | no, it's not | 11:36 |
| ikonia | what is the "E" in lemp ? | 11:36 |
| taliptako | hmm i have interesting problem | 11:37 |
| taliptako | let me explain maybe you can guess :) | 11:37 |
| ikonia | no | 11:37 |
| ikonia | just tell me | 11:37 |
| ikonia | I'm not playing a game, I'm trying to understand your setup | 11:37 |
| ikonia | what does the "E" in lemp stack reference | 11:37 |
| taliptako | i have website and i'm using php and visitors uploading images okey and i save them to uploads/ folder i create a folder for all images for example /dog/1.jpg also i create conversions folder in dog folder /dog/conversions/230x300px.jpg(example) | 11:38 |
| ikonia | ok - so you're not answering my question | 11:39 |
| taliptako | i resize images and putting them to conversions folder and i resize them with php-gd library of course | 11:39 |
| ikonia | I'm afraid I can't help you | 11:39 |
| taliptako | conversions folder owned by root | 11:39 |
| taliptako | just conversions folder all my others folders files doesnt have this problem but images resized with php-gd owned by root | 11:40 |
| taliptako | and when i try to delete them its causing the permission denied problem | 11:40 |
| taliptako | Nginx - php - mysql ikonia | 11:40 |
| ikonia | so you actually don't understand what you're saying then | 11:40 |
| ikonia | LAMP = Linux Apache PHP Mysql | 11:40 |
| ikonia | LEMP = Linux ??? Mysql Php | 11:41 |
| ikonia | so what's the E ? | 11:41 |
| taliptako | https://lemp.io/ | 11:41 |
| taliptako | look here | 11:41 |
| ikonia | no | 11:41 |
| ikonia | just answer the question | 11:41 |
| ikonia | actually, I can't be bothered | 11:41 |
| ikonia | good look sorting yourself out | 11:41 |
| taliptako | We go with LEMP due to the pronunciation for Nginx: Engine-X (en-juhn-ecks). Think of how in English, the article an is used instead of a for hour even though it begins with a consonant. | 11:41 |
| RoyK | ikonia: E for Evangelist :D | 11:43 |
| ikonia | ha | 11:44 |
| RoyK | taliptako: that should be LNMP, though, since nginx is spelt with an n... | 11:45 |
| RoyK | and btw, don't use mysql if you can use postgresql :P | 11:46 |
| taliptako | i dont care | 11:46 |
| taliptako | if its lemp or lnmp :) | 11:46 |
| RoyK | hm - windows, iis, mysql and php, that should be like wimp, right? ;) | 11:47 |
| gasconheart | ikonia: thanks for your reply | 11:48 |
| ikonia | gasconheart: no problem | 11:49 |
| gasconheart | (I'm looking after a kid over here) | 11:49 |
| gasconheart | ikonia: some guy here suggested it might be related to the dirty cow vulnerability | 11:49 |
| ikonia | gasconheart: not sure how they could make ANY guess based on that single bit of output of a stack trace | 11:49 |
| gasconheart | is there anything that might point to dirty cow? | 11:50 |
| gasconheart | oh | 11:50 |
| gasconheart | I check my logs all the time, almost paranoidly, I found no strange logins | 11:51 |
| gasconheart | I am close to 100% positive it was not a hacking attempt; does anything in that screenshot suggest otherwise? thanks | 11:53 |

| taliptako | soo guys there is no difference using sudo or directly writing commands as a root ? | 12:09 |
| taliptako | for sure ? | 12:09 |
| andol | taliptako: You usually end having different environment variables set, which might affect how the commands run. | 12:17 |
| ikonia | gasconheart: that screenshot suggests nothing | 12:18 |
| bor691 | hello, i'm having trouble changing /etc/sshd_config (it doesn't affect anything even after reboot) on ubuntu server 14.04. i check the value with sshd -T after modifying the file but still shows the old value... | 13:50 |
| ikonia | bor691: what value are you changing | 13:55 |
| bor691 | i intended to do a reverse tunnel that binds to non-local interface , some questions in serverfault and askubuntu suggested changing gatewayports | 13:56 |
| bor691 | but after that didn't work i tried setting passwordauthentication no | 13:56 |
| bor691 | just to test if it changes , but it didn't , sshd -T shows no and i can still login via password, even after restarting the service and rebooting the server | 13:57 |
| bor691 | is there a way to get address of the loaded config file ? is it possible that i'm chainging the wrong file ? (i was modifying /etc/ssh/ssh_config , and verified that the file is saved with the new value) | 14:01 |
| ikonia | bor691: you need sshd_config | 14:01 |
| ikonia | ssh_config is the client | 14:01 |
| bor691 | now i feel like an idiot :| tnx | 14:02 |
| ikonia | no problem, easy to miss it, nothing silly about it | 14:03 |

| al_nz1 | Anyone here using Nagios? | 18:45 |
| al_nz1 | I want pretty graphcs | 18:50 |
| al_nz1 | network graphs :-) | 18:50 |
| spammy | al_nz1: I use icinga | 19:01 |
| spammy | a fork of nagios | 19:01 |
| al_nz1 | Hi spammy. I only went with nagios because it seems widely known | 19:01 |
| al_nz1 | and I hoped well supported | 19:02 |
| al_nz1 | bit of a steep learning curve so far | 19:02 |
| spammy | icinga is in Ubuntu's repo | 19:02 |
| spammy | works like nagios | 19:02 |
| spammy | well supported | 19:02 |
| al_nz1 | ok. I will take a look | 19:02 |
| spammy | I've also been playing with Zabbix, it seems a bit easier than Nagios/Icinga | 19:04 |
| spammy | you can add hosts etc. in gui | 19:04 |
| spammy | which is nice | 19:05 |
| al_nz1 | yeah - that would be nice | 19:05 |
| spammy | there's a PPA for Zabbix | 19:05 |
| al_nz1 | easy is better at this point | 19:05 |
| al_nz1 | is it in repo? | 19:05 |
| spammy | in a PPA repo....hang on, I'll look it up | 19:06 |
| spammy | whoops....my bad, not a PPA but a zabbix official repo | 19:08 |
| spammy | https://www.zabbix.com/documentation/3.2/manual/installation/install_from_packages/repository_installation | 19:08 |
| spammy | Ubuntu steps to install repo are at the end | 19:09 |
| spammy | then follow these instructions... | 19:09 |
| spammy | https://www.zabbix.com/documentation/3.2/manual/installation/install_from_packages/server_installation_with_mysql | 19:09 |
| spammy | or the postgres one, depending on which db flavor you want | 19:10 |
| al_nz1 | ok | 19:27 |
| al_nz1 | ta | 19:27 |
| al_nz1 | why the heck do I not have a httpd.conf on apache2 | 19:37 |
| al_nz1 | find / -name httpd.conf is empty | 19:37 |
| Pici | al_nz1: its /etc/apache2/apache2.conf conf for whatever reason | 19:38 |
| al_nz1 | ok | 19:38 |
| al_nz1 | just found that in google | 19:38 |
| al_nz1 | ta | 19:38 |
| === JanC_ is now known as JanC | ||
| al_nz1 | I am getting Forbidden: You don't have permission to access /nagiosgraph/cgi-bin/show.cgi on this server. | 20:59 |
| al_nz1 | How do I resolve this on ubuntu16 / apache2 | 20:59 |
| tsimonq2 | al_nz1: 16.04 or 16.10? | 21:03 |
| al_nz1 | tsimonq2: 16.04 | 21:57 |
| al_nz1 | but I have restarted the installation of nagios from scratch | 21:57 |
| al_nz1 | you still about tsimonq2 | 22:38 |
