| a1fa | has anybody noticed random high ports being open (or at least randomly responding) with no tcp listeners? | 01:49 |
|---|---|---|
| a1fa | $ nmap localhost -p 0-65535 | 01:49 |
| a1fa | 40424/tcp open unknown | 01:49 |
| a1fa | 41820/tcp open unknown | 01:49 |
| a1fa | ... | 01:50 |
| a1fa | 59865/tcp open unknown | 01:50 |
| a1fa | goofy... whatever is causing it (tested on fresh build/air gap) | 01:51 |
| a1fa | and it only happens if a non priviledged user does a port scan | 01:52 |
| a1fa | can anyone else confirm the same behaviour? as a non root user run nmap localhost -p 0-65535 | 02:00 |
| a1fa | several times in a row | 02:00 |
| teward | a1fa: any specific OS you want tested, or just any Ubuntu? | 02:02 |
| a1fa | 15.04 or 14.04 | 02:03 |
| a1fa | 14.04.02 | 02:03 |
| a1fa | and 15.04 with 3.19.0-24-generic | 02:03 |
| teward | stupid question but | 02:03 |
| teward | you wouldn't happen to have dhcp on your network would you? | 02:03 |
| teward | (dhclient might be listening on random high ports for DHCP changes and such) | 02:04 |
| a1fa | i do | 02:06 |
| teward | i can replicate the behavior on wily, but only insomuchas there's only one open port | 02:06 |
| teward | a random high tcp port on my side | 02:06 |
| teward | and only one | 02:06 |
| teward | multiple UDP ports are 'listened' on by dhclient | 02:07 |
| a1fa | odd | 02:08 |
| teward | and i just saw one with a few high number random TCP ports open | 02:08 |
| teward | but the next scan they're gone | 02:08 |
| a1fa | it only happens with non-root user | 02:09 |
| teward | which makes me think they're destructible connections - since high ports are usually used for client-initiated TCP | 02:09 |
| teward | and nmap needs those too iirc | 02:09 |
| a1fa | i did see S/Ack on tcpdump | 02:09 |
| a1fa | so forwhatever reason, something answered, followed by RST | 02:10 |
| a1fa | just tested the same thing on a chromebook, same behaviour | 02:10 |
| teward | lemme start up my CentOS box | 02:11 |
| teward | and see if it's replicated there too | 02:12 |
| teward | my guess is it's standard stuff happening | 02:12 |
| patdk-lap | doesn't happen for me at all, on 14.04.2 | 02:14 |
| patdk-lap | you didn't happen to *run out* of available ports did you? | 02:14 |
| teward | i'll spin up my ubuntu server vm to test in a moment | 02:14 |
| patdk-lap | cycling through them too fast, in time-wait | 02:14 |
| patdk-lap | hmm, atleast with *that* nmap command, they aren't going to time-wait, cause they aren't full tcp session test | 02:15 |
| a1fa | patdk-lap: thats what i was thinking.. but i saw a s/ack | 02:15 |
| patdk-lap | could be hundreds of reasons | 02:16 |
| patdk-lap | depending on what you have installed | 02:16 |
| a1fa | base | 02:16 |
| patdk-lap | I know I only install minimal-installs so | 02:16 |
| patdk-lap | don't know what base is | 02:16 |
| a1fa | basically nothing besides what comes on a default install | 02:17 |
| patdk-lap | ya, I never install that *much* | 02:17 |
| a1fa | the odd thing is, its doing it on the chromebook too | 02:17 |
| a1fa | running chromeos+14.04.02 | 02:18 |
| patdk-lap | about 30, nmap runs now | 02:18 |
| patdk-lap | and always the same 3 ports, of stuff I have running | 02:18 |
| patdk-lap | ssh/http/munin | 02:18 |
| teward | dhclient gets involved a little at some point | 02:18 |
| a1fa | running as non root user, right? | 02:18 |
| teward | centos can't replicate this | 02:18 |
| patdk-lap | oh non root? that will ahve other things | 02:18 |
| a1fa | what kernel version teward | 02:19 |
| teward | a1fa: for...? | 02:19 |
| a1fa | centos | 02:19 |
| teward | centos? you're 30 seconds slow i already powered off the VM | 02:19 |
| a1fa | :P | 02:19 |
| teward | i'll tell you after i test on my Trusty VM | 02:19 |
| a1fa | k | 02:19 |
| patdk-lap | ok, as non-root | 02:20 |
| patdk-lap | it happens, and also happens on rhel7 | 02:21 |
| a1fa | its worth looking into it, and maybe opening a bug | 02:21 |
| patdk-lap | why? | 02:21 |
| patdk-lap | so far it's not worth it at all | 02:21 |
| a1fa | it's not supposed to ack back at all | 02:22 |
| teward | ran nmap 5 times and it started to show open ports locally | 02:22 |
| teward | in rapid succession | 02:22 |
| teward | otherwise it wasn't giving any ports (14.04) | 02:22 |
| patdk-lap | nmap just acts funky when you don't use it as root | 02:22 |
| teward | mhm | 02:22 |
| patdk-lap | cause it can't use raw sockets | 02:22 |
| patdk-lap | so it attempts to do the best it can | 02:23 |
| a1fa | patdk-lap: but the system responds back with s/ack on those prots | 02:23 |
| a1fa | confirmed with tcpdump. on both loopback and actual interface ip | 02:23 |
| patdk-lap | both use loopback interface | 02:24 |
| patdk-lap | what happens if you use a remote ip? | 02:24 |
| a1fa | no ports show up | 02:24 |
| a1fa | i'll do some more work tomorrow to debug it | 02:25 |
| a1fa | thanks for confirming | 02:27 |
| PryMar56 | on a new install of Vivid server, my `systemd-analyze time` shows too much kernel time (>20s). Anyway to improve this? | 02:30 |
| PryMar56 | ^ kernel time should be about 5s | 02:30 |

| lordievader | Good morning. | 06:56 |
| ObrienDave | o/ | 06:57 |
| mobile3 | anyone ? | 07:04 |
| lordievader | mobile3: ? | 07:05 |
| mobile3 | Can you help me with Webuzo Control Panel on VPS ? | 07:06 |
| mobile3 | Ubuntu 14.04 x64 | 07:06 |
| lordievader | Ah, no. But do ask your questions. | 07:06 |
| * ObrienDave does not want to know what webuzo is ;P | 07:06 | |
| lordievader | ObrienDave: No adventure in the early morning? | 07:08 |
| ObrienDave | getting close to sleepy time :) | 07:08 |
| mobile3 | I have been given 4 IP , while installing webuzo 1 IP got bonded to it... I have placed index.php file in public_html folder... when I am accessing via bonded IP , I am able to get correct index.php file but with all other 3 IP , I am getting different things.. | 07:08 |
| mobile3 | What to do so that I can get the same index.php file from all of my IP ?? | 07:09 |
| lordievader | Vhost configuration? | 07:09 |
| OerHeks | easy to add an extra ip to your machine, manually .. http://askubuntu.com/a/313887 | 07:10 |
| lordievader | mobile3: Who set up the Web server? | 07:10 |
| mobile3 | lordievader: they gave me with Ubuntu 14.04 x6 | 07:11 |
| mobile3 | minimal installed | 07:11 |
| mobile3 | I changed it to Ubuntu 14.04 x64 | 07:11 |
| lordievader | mobile3: So you control the Web server config? | 07:12 |
| mobile3 | ya I can... | 07:13 |
| mobile3 | How to solve this problem ? | 07:14 |
| lordievader | mobile3: Check the vhost configuration. | 07:14 |
| mobile3 | how ? | 07:14 |
| lordievader | By reading the configuration/ | 07:15 |
| lordievader | mobile3: Step 4 in this tutorial shows how vhosts are configured: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-14-04-lts | 07:15 |
| lordievader | In that particular case it is any incoming request on port 80. | 07:16 |
| mobile3 | not such file /etc/apache2/sites-available/000-default.conf | 07:21 |
| mobile3 | in my server | 07:21 |
| lordievader | mobile3: What is in /etc/apache2/sites-available? | 07:22 |
| mobile3 | No apache2 folder | 07:22 |
| lordievader | mobile3: What Web server are you using to serve your control panel? | 07:25 |
| mobile3 | Ubuntu 14.04 x64 .... Webuzo Control Panel | 07:26 |
| lordievader | mobile3: That is not a Web server. | 07:26 |
| mobile3 | Apache | 07:27 |
| mobile3 | lordievader : Apache Version : 2.2.29 | 07:28 |
| lordievader | But you have no /etc/apache2? Where is your Apache coming from? | 07:28 |
| mobile3 | I don't know ! | 07:29 |
| lordievader | mobile3: What is the output of 'apt-cache policy apache2'? | 07:30 |
| mobile3 | apache2: Installed: (none) Candidate: 2.4.7-1ubuntu4.4 Version table: 2.4.7-1ubuntu4.4 0 500 http://archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu/ trusty-security/main amd64 Packages 2.4.7-1ubuntu4 0 500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages | 07:30 |

| lordievader | mobile3: That is not installed... Is Apache coming from outside of the repo? | 07:32 |
| mobile3 | I don't know... | 07:33 |
| lordievader | mobile3: What is the output of 'whereis apache2'? | 07:34 |
| mobile3 | whereis apache2 apache2: | 07:34 |
| lordievader | Huh? How did you just get the version information? | 07:37 |
| mobile3 | lordievader :http://www.awesomescreenshot.com/image/436540/dcbc63865c203be5ee4bce22fa8caea7 | 07:44 |
| lordievader | Ugh, does that thing do its own software installation? | 07:45 |
| neonixcoder | I am upgrading 10.04 to 12.04 but middle of upgrade my system reboots.. | 07:45 |
| neonixcoder | When checked system logs it states that "locale: /lib/libc.so.6: version `GLIBC_2.15' not found (required by locale)" | 07:46 |
| neonixcoder | My present glibc version is 2.11.. | 07:46 |
| neonixcoder | any suggetions? | 07:46 |
| mobile3 | lordievader : may be but I don't know | 07:47 |
| jelly | neonixcoder: verify versions of libc6, libc-bin and locales packages. Make sure they match by installing and/or configuring them manually if needed, then finish your release upgrade. | 07:50 |
| jelly | neonixcoder: newer versions of .deb package files will have been downloaded into /var/cache/apt/archives/ | 07:51 |
| neonixcoder | ok? | 07:52 |
| neonixcoder | Thanks for your reply.. | 07:52 |
| neonixcoder | jelly: when I checked with apt-cache policy for libc6 and libc-bin it shows installed is 2.11 and candidate is 2.15. But for locales it shows installed and candidate as 2.11 | 07:54 |
| neonixcoder | Any thoughts on this? | 07:54 |
| mobile3 | lordievader : are you there ? | 07:54 |
| Amillo | Hey guys, if I nslookup my zone 'test.co.uk' and it returns the server as a loopback does this mean I've configured something wrong? | 07:55 |
| jelly | neonixcoder: both of those are unusual for 12.04. My 12.04 installation has locales: Installed: 2.13+git20120306-3 Candidate: 2.13+git20120306-3 | 07:55 |
| lordievader | mobile3: Still here, just busy. Anyhow I get the feeling it does install its own packages. I have no idea how, why or where. So I really cannot help you. | 07:55 |
| neonixcoder | jelly: I am still on 10.04 machine.. | 07:56 |
| mobile3 | lordievader : okay | 07:56 |
| neonixcoder | I am upgrading from 10.04 to 12.04 | 07:56 |
| lordievader | neonixcoder: Restart the upgrade? | 07:57 |
| jelly | neonixcoder: pastebin the output of "apt-cache policy" and "apt-cache policy libc6 libc-bin locales" please | 07:59 |
| neonixcoder | lordievader and jelly: Let me give some background here.. | 07:59 |
| neonixcoder | I have some 200 machines need to upgrade from 10.04 to 12.04(Intention is to upgrade to 14.04). I have some test machines where I can upgrade multiple times if something went wrong.. | 08:01 |
| neonixcoder | I am going to follow http://askubuntu.com/questions/125742/why-did-my-upgrade-to-12-04-fail-with-glibc-not-found-or-libc6-or-requires | 08:01 |
| neonixcoder | from there I install that PPA which is giving me 2.15 versions for libc6 and libc-bin | 08:02 |
| jelly | neonixcoder: oh dear | 08:02 |
| lordievader | Somewhere that sounds like a bad idea. | 08:03 |
| tonyyarusso | ........PPA for libc6? *grabs popcorn* | 08:03 |
| jelly | neonixcoder: well, good luck with that, I won't be able to help with that mess | 08:03 |
| neonixcoder | Ok.. Let me remove that ppa from list then.. | 08:04 |
| neonixcoder | I did not try to upgrade it with that PPA, before doing it I want your valuable advice.. | 08:04 |
| lordievader | neonixcoder: Did you install anything from the ppa? | 08:05 |
| neonixcoder | right now no.. | 08:05 |
| neonixcoder | Just added it.. | 08:05 |
| lordievader | Phew, doged a bulled. | 08:05 |
| lordievader | bullet* | 08:05 |
| * jelly would prefer to the valuable current state of the system before dispensing potentially harmful advice | 08:05 | |
| jelly | to see* | 08:06 |
| neonixcoder | jelly: My present policy list is http://pastebin.com/Lugf3j7N | 08:16 |
| neonixcoder | any suggetions? | 08:16 |
| neonixcoder | jelly:Any thoughts on how to proceed with upgrade? | 08:28 |
| neonixcoder | Any suggestions guys? | 08:33 |
| neonixcoder | How can I upgrade with out glibc issue? | 08:33 |
| neonixcoder | Quick recap.. I removed ppa and given my apt-get cache stuff.. | 08:49 |
| neonixcoder | Or can I know which repo provides glibc? | 08:52 |
| neonixcoder | going home, ping you people tomorrow | 08:58 |

| gmaciolek | Wow, tis weechat client integrates screenshot links. | 14:47 |
| gmaciolek | *this | 14:47 |
| gmaciolek | So, I'm wondering, what are people using for centralized update management these days? (It looks like Landscape is an option. but O | 14:48 |
| gmaciolek | *I'm hoping for FOSS, and ideally a tool that'll work on deb & rpm distros | 14:48 |
| maswan | automatic updates | 14:49 |
| teward | ^ that | 14:51 |
| teward | but if you want centralized management of Ubuntu servers, it's Landscape (but that can be expensive) | 14:51 |
| teward | or puppet or other multisystem management systems | 14:51 |
| lordievader | Puppet is rather nice. | 14:52 |
| teward | lordievader: when configured right, yes. | 14:53 |
| lordievader | True, it can be painfull too ;) | 14:53 |
| OerHeks | landscape is up to 10 servers free, no ? | 14:54 |
| teward | OerHeks: when you set it up on your own system, 10 physical machines, 10 virtual | 14:55 |
| teward | OerHeks: i use it to manage my VPSes (which get listed on the Virtual category) | 14:55 |
| teward | problem is you actually have to set it up, as the 'cloud' one from Canonical needs the Advantage licenses | 14:56 |
| OerHeks | Nice, it is indeed good usable for small business | 14:56 |
| teward | OerHeks: provided there's only 10 physical and 10 virtual machines | 14:56 |
| garethdaine | Guys, how long should it take to wipe and reinstall a fresh Ubuntu server, only running Ubuntu 14.04 x64 on a machine with 16GB RAM? | 14:56 |
| maswan | garethdaine: Mostly depends on the storage and set of installed packages | 14:58 |
| maswan | garethdaine: writeback cache on the storage is a factor 10-100 | 14:58 |
| maswan | compared to slow spinning disks without | 14:59 |
| garethdaine | But it shouldn;t take 4 hours should it? | 15:00 |
| garethdaine | Being installed by professionals | 15:00 |
| garethdaine | I’ve asked our dedicated host to wipe the server and install only a fresh copy of Ubuntu 14.04 x64 and they are saying it’s 4 hours chargable work | 15:00 |
| teward | garethdaine: they probably have to do things at the datacenter to make the revisions - network reconfiguration, configuration for networking, etc. | 15:01 |
| teward | depending on what all they ahve to do over at the datacenter it could very well be 4 hours of work for them | 15:01 |
| tgm4883 | teward: assuming that it had a previous version of Ubuntu server on there, what else would they need to reconfigure? | 15:03 |
| garethdaine | Hmmm, really? Thought it took like 30 minutes to install | 15:03 |
| rbasak | 30 minutes within an 80% confidence interval maybe | 15:03 |
| rbasak | (if the hardware isn't Ubuntu certified, etc) | 15:04 |
| rbasak | If quoting in advance it makes sense to add contingency time, for example if there are driver issues. | 15:04 |
| rbasak | Or if the hardware turns out to be faulty. | 15:04 |
| rbasak | Etc. | 15:04 |
| tgm4883 | rbasak: true, I suppose there are a lot of unknowns here | 15:04 |
| OerHeks | even with a dedicated host you should be able to put an image back yourself. | 15:06 |
| garethdaine | rbasak: Shouldn’t have faulty hardware, it’s current live server that’s just getting a reinstall | 15:08 |
| rbasak | Disks can have latent errors that only show up when doing big things to them. | 15:11 |
| rbasak | This is why double RAID failures happen. Because only on attempt to reconstruct does the second disk fail. | 15:12 |
| garethdaine | OK, thanks for the help folks. Should I question the quote I have received and ask them to detail what is taking the 4 hours, or should I just accept that it can take 4 hours? | 15:17 |
| teward | garethdaine: i would, but i'm anal about making sure they're not doing extra work | 15:18 |
| rbasak | I would consider what your service costs you overall and what you get for that money, as compared to competitors. | 15:19 |
| teward | right | 15:19 |
| teward | garethdaine: although, if they have to redo the RAID to reinstall that could potentially explain a large time for completion | 15:19 |
| teward | (build the array, verify the array's integrity, etc.) | 15:19 |
| teward | but i woudl do that comparison rbasak says as well | 15:19 |
| teward | AND ask what the 4 hours entails | 15:20 |
| garethdaine | Yes, I will do that teward | 15:23 |
| garethdaine | Thanks for the help | 15:25 |

| bilde2910 | install linux-image-3.13.0-59-generic_3.13.0-59.98_amd64.deb because the device is full. No space left on device. I then try apt-get autoremove to free some space, but I get the same errors as before. Running Ubuntu Server 14.04.2 LTS on amd64. Any help? | 19:25 |
| sarnold | bilde2910: use apt-get purge to manually delete specific packages | 19:26 |
| bilde2910 | Just tried that too, and nope, I can't because aforementioned dependencies are not met | 19:27 |
| sarnold | bilde2910: start deleting the dependencies, too | 19:27 |
| bilde2910 | Should I try using -f? Or is that dangerous? | 19:27 |
| sarnold | bilde2910: you can always re-install the metapackages once you're done | 19:27 |
| bilde2910 | I don't really have much experience with Linux and Ubuntu and servers, so I'm not exactly sure which packages should be present and which shouldn't | 19:28 |
| bilde2910 | Is it safe to manually delete some of the older ones of these files? http://paste.ubuntu.com/11950111/ | 19:39 |
| sarnold | bilde2910: yeah; if you truncate them instead of delete them, it'll make some deleting steps easier.. | 19:43 |
| sarnold | bilde2910: be sure to keep at least two -- whatever you're currently running, and the newest. if you're running the newest, then keep the next-oldest.. | 19:44 |
| sarnold | or next-newest | 19:44 |

| hexaclock | anyone know if there's a way to assemble mdadm raid arrays in a particular order? | 19:45 |
| hexaclock | i have a raid60 made up of 2 raid6 arrays | 19:45 |
| hexaclock | anytime that i reboot this box, i need to manually assemble the raid0 array (the underlying raid6 arrays assemble just fine on boot without any intervention) | 19:46 |
| hexaclock | i could always throw something in /etc/rc.local or such, but i'm wondering if there is a cleaner way? | 19:46 |
| TJ- | hexaclock: the arrays are assembled via udevd triggers, so how about a custom rule that assembles the RAiD0 once the 2 underlying arrays are ready | 19:51 |
| TJ- | hexaclock: along the lines of: when a RAID6 is added: 1) if /run/raid6 already exists then assemble the RAID0 and delete /run/raid6, otherwise "touch /run/raid6" | 19:53 |
| hexaclock | awesome, i'll look into it | 19:54 |
| hexaclock | thanks! | 19:54 |
| TJ- | hexaclock: "/lib/udev/rules.d/64-md-raid.rules" might give you some clues on how to recognise the mdadm array is ready; your rule will want to be in "/etc/udev/rules.d/" and have a different number/name than the system mdadm rule to avoid over-riding it | 19:56 |
| bilde2910 | sarnold, another question: How do I know which of the files I use? E.g. I have 8 of initrd.img-$version-generic, how do I know which one is the one my system uses? | 20:05 |
| sarnold | bilde2910: uname -a output | 20:05 |
| bilde2910 | Ah, thank you :) | 20:06 |
| tanuki | I have Trusty server running as a headless VM (on another Trusty server machine). A few times now, the VM has spontaneously booted into memtest86+. | 20:26 |
| tanuki | Any idea why? | 20:27 |

| bekks | tanuki: You need to investigate the logs in /var/log/ | 20:41 |
| tanuki | Paradoxically, the thing that pisses me off is when things *don't* fail (when I want them to). | 20:48 |
| bekks | I dont want things to fail :) | 20:49 |
| TJ- | tanuki: Is there anything non-standard about the server installation, any custom boot-loader configuration, anything unusual about the disk images being provided to the guest by the host? | 20:49 |
| tanuki | TJ-: Not to my knowledge, with the exception of choosing "minimal virtual machine" instead of "minimal system". | 20:50 |
| tanuki | bekks: I want things to fail when I need to know why they fail. | 20:50 |
| TJ- | tanuki: there were 2 things I would focus on... is the root file-system image separate to the /boot/ image and if so is the rootfs image present and ready, and if they are, then has grub set a different 'default' boot entry that happens to be the memtest86+ entry in some circumstances.... the only other option I can think is something running in the guest that actively causes a reboot to memtest86 | 20:52 |
| tanuki | This server isn't used for anything, really (basically, it's a development box for things), so I'm tempted to just set up a cron job on the host that checks that sshd is running on the guest and fires off an email otherwise | 20:54 |
| tanuki | I'm more concerned with power consumption than anything else. | 20:54 |

| jak2000 | how to change the linux hostname? | 22:02 |
| pmatulis | jak2000: edit /etc/hostname and /etc/hosts, then reboot. can avoid a reboot with 'sudo sysctl -w kernel.hostname=<hostname>' | 22:07 |
| pmatulis | the only place where a domain name enters into the mix is in /etc/hosts. everywhere else hostname is just the first part of the FQDN (up to the first dot) | 22:08 |
| jak2000 | ok thanks | 22:09 |
