[00:01] NwS: was the log file in question even closed by the program that's writing it? [00:02] sarnold, no idea.. I thought logrotate would deal with it [00:03] NwS: many programs will close their log file and re-open if you send them a SIGHUP or SIGUSR1 or something; check the manpage for the program that writes the file [00:06] sarnold, okie mate I'll check it out tyvm [00:11] sarnold, seems like apache is the program [00:11] stopping it didn't help :P [00:13] NwS: check lsof output for " (deleted)" files [00:14] sarnold, I can see the log files there hmm [00:15] the PID is apache under www-data user [02:47] ok [02:47] so which files system is the way to go? [02:47] for which purpose? [02:47] server os one hdd [02:48] storage the other [02:48] ext4 is probably a reasonable choice if you've just got one drive and don't care about bitrot [02:49] thanks [02:50] APCI PCC probe failed? [02:50] what does that mean [02:53] Billy21: heh https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1524930 [02:53] Launchpad bug 1524930 in linux (Ubuntu Vivid) ""ACPI PCC probe failed" message is an error message when it should be debug" [Low,Fix released] [02:53] anyone know a good network scanning utility? ive recently switched isp's and bought a new modem. since then ive experienced frequent "broken pipes" while trying to ssh into my ubuntu 14.04 server. this wouldnt be a huge problem thanks to gnu screen and the like, but one of the main functions of the server is its samba shares which disapear on any of my smb clients nix or windows, when i get these... blips... any help would be apreciated! [02:57] after a bit of googling ive turned up nmap. trying it as we speak. [02:57] nmap's great for mapping, not as great for determining quality-of-service [02:59] i really need a way to test the only real changes to my network modem/isp because it was working flawlessly before. [03:03] I've used netalyzr on my phone before; apparently they have a desktop version too but step one is "run this java application" and i've never gotten that far. [03:04] netalyzr can find some pretty impressive things though, even on the phone [03:04] something like smokeping or mtr --report may be useful to try to diagnose packet loss problems [03:05] broken PMTU discovery can also lead to problems, I'm not sure the best way to test for that, but it'd be worth investigating [03:06] nice thanks for the info, looking into it now. [03:06] of course these guys give a great first-stop is-it-anywhere-near-sane kind of test http://www.speedtest.net/?a=1 [03:07] ahh good ol' okala, nah their test works great this is something more suble im sure. it happens about once every 5-15 mins like clockwork. [03:35] anyone broken dhcp on xenial [03:36] Fudge: heh those bugs are all over the place; mixing dhcpd with dhcpcd and dhclient and _bind_(!?) and so on.. [03:38] Fudge: if none of the bugs that you've seen or commented on are exactly the one issue that you've got, it might be best to open a new bug, and be specific in the bug description whether it's the client or the server or whatever, with error messages as you can find them, to help prevent the bug from being hijacked by unrelated errors [03:40] so netalyzr is pretty neat it actually turned up some interesting stuff regarding my isp's dns resolver. [03:41] sarnold: hi, thanks for your reply mate. I have created a new bug and commented on two others which describe my problem exactly, this bug seems to keep raising its ugly hed each cycle. But no one has replied and poking the dev hasn't helped either. i'm a bit frustrated tbh, a friend with the same setup is also having the same issues so it does not appear to be something local to my environment. [03:43] Fudge: *nod* that makes sense.. there's too much to do and not enough time to do it :( [03:46] sarnold: I do appreciate that for sure, maybe moving apparmor out of the way will help, I would hate to have to roll back to my Trusty though. [03:47] i guess it doesnt help that my times dont align with jdstrand very much. he is on UK time i tseems whilst I am on Australian time [03:48] Fudge: hah, he's texas time :) [03:48] Fudge: if apparmor's in the way, grab those DENIED lines. everything revolves around those. [03:48] roger D [03:58] sarnold: this is wirird, this is from journalctl grep -i dhclient. its not a big pastebin maybe 20 lines. http://paste.ubuntu.com/15249415/ [03:58] one error says couldnt reach network make sure the broadcast address is correct, but my interfaces file is basically iface eth0 dhcp [03:59] this is how I am keeping my connection alive [03:59] Mar 01 07:00:01 dominion CRON[9962]: (root) CMD (/sbin/dhclient eth0 >/dev/null 2>&1) [03:59] every 20 minutes [04:00] Fudge: is there anything in dmesg that may explain the interface dissapearing/ [04:01] [ 4.093635] e1000 0000:06:07.0 enp6s7: renamed from eth0 [04:02] cat /etc/udev/rules.d/10-network.rules | pastebinit [04:02] http://paste.ubuntu.com/15249443/ [04:03] hmm. that should run a few seconds later.. [04:03] I thought that once they were renamed it was static [04:04] should i revert the interface names and see if it is still happening? [04:05] I wonder if there's some unfortunate interactions between the rename command and the dhclient startup unit [04:06] do you think I should go find some dhcp folk ? [04:06] I like your idea of trying to use the en6p7 or whatever name.. [04:07] ok, it sucks because i cant remember their names, actually let me just check my bash history fir dhclient requests [04:07] dhclient enp6s7 [04:07] dhclient enp6s7 [04:08] plus lots more of times ive just requested an ip to get back online,m can try reverting but seems i already had the problem before i changed [04:10] only 16 peeps in #isc-dhcp but im asking [04:19] sarnold: do you understand ip routing much, this is my output [04:19] unicast default via 203.206.58.255 dev eth0 proto boot scope global [04:19] unicast 10.10.10.0/24 dev eth1 proto kernel scope link src 10.10.10.254 [04:19] unicast 203.206.56.0/21 dev eth0 proto kernel scope link src 203.206.58.81 [04:20] seems sane [04:20] I didn't do the /21 math, that's hard to do when it isn't a multiple of 8 :) [04:21] :D [04:25] sarnold: you work at Cannonical? [04:25] Fudge: yeah [04:26] pressure must have eased off abit with minor releases not being support as long hopefully [04:27] slightly; the hardest backports were usually for the oldest LTS releases, and that hasn't changed [04:28] it is nice to have e.g. only four or five supported releases to test updates on vs five or six, though, that part has been nice. :) [04:28] oh im not very goodd with packaging but tried a couple of times to backport to precise some of the accessibility stack during a python3 transition and failed after about the 20th dependency package [04:28] being a text to speech user [04:28] python feels actively mean about those things [04:29] but that's a rant for another day :) [04:29] I hear ya bud [04:32] seeing if AVAHI_DAEMON_DETECT_LOCAL=1 [04:32] in default/avahi-daemon will help as it was set to 0 and logs are showing that it messes with the interface after the ip address gets handed back to isp [05:45] hi every one,i have a question , my server was 12.04 with kernel 3.2.0.80-lowlatency ,i do upgrade to version 14.04 and when reboot system,kernel update to version 3.13.0.79-generic , i need to update with apt-get to last version,can i update to version 4 of kernel? [05:54] no answer? [06:11] dont see why you cant [06:11] keep the old one around in case it breaks [06:48] Hi Guys, wanted to ask, our server has RAID, then suddenly reboot but unable to boot, which leads to reinstallation of GRUB. it's booting now but there's a huge files missing from our files archive is there a way to retrieve it? [07:02] <_ruben> FarhaadN: installing linux-generic-lts-wily will give you wily's kernel, which is based off 4.2.0 [07:29] _ruben: i want to install low-latancy version of 4 , now kernel is 3.13 general ,no problem? [07:31] <_ruben> FarhaadN: then install linux-lowlatency-lts-wily instead [07:58] _ruben: thx ,can u tell me step by step by command? plz [07:58] or link [08:06] Good morning. [08:15] <_ruben> FarhaadN: sudo apt-get install linux-lowlatency-lts-wily [08:15] <_ruben> done [08:15] <_ruben> ;) [08:20] lordievader: my new happiness today is from 'journalct -f -o cat' [08:21] now just how to pipe that into tty12 and ill be going great [08:22] But timestamps are usefull! [08:22] Well, can be. [08:23] Piping it the the input of tty12 is probably not what you want? [08:24] i agree but since i am a text to speech user it is really annoying [08:24] since i listen to the timestamp first [08:24] Ah, I see. [08:25] Can't you then pipe it to your tts application? [08:26] how to enable ubuntu enable memtest86+ i've already install the package but update-grub doesn't detect the memtest option [08:27] _ruben: :D i think many procces to done,tnxx [08:34] yep I can, but i dont want to hear it all of the time, just when i want to look over recent events like WTF is going on lol [08:35] fishcooker: isnt it in /etc/grub.d/?

[09:24] brctl [09:24] i thin/k [09:27] Yes, brctl. brctl show, to be precise. === rvba` is now known as rvba [12:47] hello [12:48] i am going to grant permission to my friend to get access to my ubuntu server through ftp what should i do? [12:49] linuxlove: why ftp? [12:49] what are you trying to do :) [12:49] my friend and me are creating a website and he needs to get access to server [12:49] i am on ubuntu 15.10 [12:50] create a useraccount on the system using adduser [12:50] and let him use SCP [12:50] what is SCP? [12:50] then he can securely upload files into his homedirectory and any other locations you give the user access to [12:50] secure copy, which uses ssh [12:50] on what OS is hie? [12:50] he* [12:50] he is on debian [12:51] alright he can just use scp /local/path user@yourhost:/remote/path then [12:51] ftp is insecure [12:51] in terminal? [12:51] <_ruben> i'd suggest rsync in that case [12:52] yeah could use rsync as well, that will still need a useraccount thouh [12:52] what should i do now? [12:52] just create a user [12:52] linuxlove: adduser [12:52] with adduser [12:53] then he will be able to put files in /home// [12:53] and shoud i need to open any port ? [12:53] if you want him to be able to put files somewhere else, give him permissions with chown/chmod [12:53] yes, TCP 22 (SSH) should be available for him [12:53] either open it to the internet, or preferably just for his remote IP, if it's fixed [12:54] how can open port in terminal? [12:54] for tcp [12:55] why are you administering this server exactly? :) [12:55] I would not recommend hosting a multi-user system on the internet if you don't have these basic skills [12:55] it is my home system [12:55] it is my first project [12:55] i am learning yet [12:56] linuxlove: okay, just don't store anything of importance on that server :) [12:56] Sling, i do it [12:56] linuxlove: you might want to use ufw for simplified firewall management [12:57] i don't have experience with ufw though, I only use iptables [12:58] Sling, i am going to get a full access to my friend [12:58] if you trust him.. [12:58] just with a user name and password [12:58] yes i trust him we are friend for 15 years [12:58] you can give him rootaccess by adding him to the sudo group [12:59] usermod -aG sudo username [12:59] after adduser ? === unreal_ is now known as unreal [12:59] yes, the user will first need to be created [12:59] also try out https://www.codecademy.com/learn/learn-the-command-line [13:00] Sling, and how can i monitoring his action? [13:00] linuxlove: if you give him full access, you can't really [13:00] please listen Sling [13:00] I already was.. [13:01] he needs to just upload on /var/www/html directory [13:02] please say me what should i do exactly after add user [13:02] excuse me [13:02] groupadd web-content [13:02] usermod -G web-content yournewusername [13:02] usermod -G web-content www-data [13:02] chown -R yournewusername:web-content /var/www/html [13:02] find /var/www/html -type f -exec chmod 640 {} \; find /var/www/html -type d -exec chmod 750 {} \; [13:03] Speaking of competence, anyone with drbd clues on why I can't get the resync rate up beyond 40MiB/s no matter what I tune things to? [13:03] if you do those steps, the content will be owned by the new user, and apache will only be able to read all the files there [13:03] if you want multiple owners of these files, you will need ACL [13:03] maswan: did you tune your drbd settings? [13:03] and about open port ? [13:04] Sling: yeah. and "drbdsetup show" reflects the changed settings [13:04] please say me configurqtion in terminqal [13:04] Sling: Both various c-* parameters, or old-style resync-rate [13:04] maswan: have you identified what the bottleneck is? 'glances' or 'atop' might show [13:04] could be various things [13:04] Sling: System idle, no iowait, network iperfs to 1120:ish MiB/s [13:04] well, systems [13:05] linuxlove: iptables -I INPUT -j ACCEPT -p tcp -m tcp --dport 22 -s 1.2.3.4/32 [13:05] where 1.2.3.4 is your friends' IP [13:05] writing to the drbd after sync gives 300:ish MiB/s [13:05] sudo apt-get install iptables-persistent [13:05] and save ipv4 rules when prompted [13:05] of network traffic to the slave [13:05] that way you won't loose the firewall config after reboot [13:06] now I'm done spoonfeeding [13:06] learn how to use your system :) [13:06] With some c-* settings I can make it go a bit slower, and crawling up to the ceiling of 40+-2MiB/s [13:06] maswan: what is on the storage layer? is it a plain disk, or swraid/hwraid, or.. ? [13:06] Sling: hw-raid6 on 12 drives, write-back cache [13:07] Sling, what is 1.2.3.4/32? [13:07] Sling: But since neither side shows a single % iowait, I'm not really suspecting that [13:07] maybe with ethtool you can check if there are network errors [13:07] faulty link, settings, etc [13:07] linuxlove: 14:05:12 < Sling> where 1.2.3.4 is your friends' IP [13:07] hm. yeah, I'd expect iperf to be as sensitive to that though [13:09] Sling: For something like c-fill-target you set a target for bytes "in flight", do you know if there is a good way of seeing what that number is right now? I don't seem to find a good match in /proc/drbd [13:11] Sling, i dunno my friends ip [13:11] Sling, how can i configure while i dunno mi friendsip [13:11] linuxlove: If you don't know your friends IP, you have to open it to the whole internet [13:11] and i need to multiple access to webcontent [13:11] Or learn your friend's IP [13:12] okay [13:12] Sling, about multiple access to web content? [13:13] Sling, you will need ACL [13:16] maswan, iptables -I INPUT -j ACCEPT -p tcp -m tcp --dport 22 is okay for whole internet? [13:17] I tihnk so, I'm not very fluent in iptables personally though [13:17] I found ufw a blessing to deal with them. :) [13:17] Sling, are you response ? [13:26] Sling, ? [13:42] maswan: I usually recommend 'ferm' for building firewall rules === Error404NotFound is now known as Guest86464 [14:32] hello [14:32] ssh localhost works for me but ssh my ip server doesnt work for me what should i do? [14:37] is this on your LAN? [14:38] hateball, no [14:38] i am on a server [14:39] on ubuntu 15.10 [14:39] linuxlove: Is sshd listening to your server ip and does the firewall allow connections to that ip? [14:42] lordievader, i am on server now and ftp://localhost and ssh localhost both works for me but when i use ftp://ip of server in internet i cant connect [14:42] and i ran sudo service vsftpd start [14:43] i have configured my modem and when i enter my ip in the internet o connect to my apache [14:43] i see my welcome page in appache [14:43] linuxlove: Can you answer my question? [14:44] lordievader, how can i know sshd is listening to my server ip? [14:44] linuxlove: Check the config or run 'sudo netstat -tulpn|grep sshd'. [14:47] tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 6989/sshd [14:47] tcp6 0 0 :::22 :::* LISTEN 6989/sshd [14:47] i think it is not listening to my ip server [14:47] how can i configure that? [14:47] /etc/sshd/ssh-config file? [14:47] It is, it is listening to any ipv4 and ipv6 address. [14:47] So it is probably your firewall. [14:47] Could you pastebin the output of 'sudo iptables -vnL'? [14:47] !paste [14:47] For posting multi-line texts into the channel, please use http://paste.ubuntu.com | To post !screenshots use http://imgur.com/ !pastebinit to paste directly from command line | Make sure you give us the URL for your paste - see also the channel topic. [14:49] lordievader, http://pastebin.com/x6Y0Q1kN [14:50] Hmm, it ain't the firewall. [14:50] i am confuse what is problem [14:50] Ssh'ing to your server should work, at least from within your lan. [14:51] You do have a working network connection from the server? [14:51] lordievader, what do you mean? [14:52] lordievader, when i enter my ip server on browser i connect to appache [14:52] Can you ping google for example. [14:52] yes [14:52] Then I do not really see why it shouldn't work. The test box is within your LAN? [14:53] lordievader, no [14:53] lordievader, please listen [14:54] i have configured my modem to use my ubuntu 15.10 as server through internet [14:54] my friend and me are creating a website [14:55] he needs to access to my /var/www/html [14:55] to upload his files for me [14:55] i need to give him a way to get access to web content [14:56] Ah, have you setup port forwarding on your router? [14:56] lordievader, yes [14:56] linuxlove: Okay, test your server within your LAN. [14:56] Does that work? [14:56] let me try [14:57] lordievader, i tested [14:58] linuxlove: So, what is the outcome? [14:58] i get this message welcome to ubuntu 15.10 when i try on my l [14:58] my lan [14:59] but i see this last login from 127.0.0.1 [14:59] So it works ;) Seems like your portforwarding is incorrectly setup. [14:59] do you know about configuration of that? [15:00] when i connect from redhat to my ubuntu through lan every thing is okay [15:01] but through internet i cant connect to my server i think it is because of just port 80 is active in portforwarding [15:02] lordievader, what should i do? [15:03] Add port 22 to the forwarding? [15:04] how can i add 2 port there? [15:04] i see service port=80 [15:04] and protocol =tcp [15:05] protocol is include tcp and all and udp [15:06] my protocol is tcp at moment [15:06] and port is 80 [15:06] lordievader, are you there? [15:07] XX-XX or XX is format at front of service port [15:08] i dunno how can i enter 2 port there [15:10] ddellav, oslo.utils and oslo.concurrency uploaded [15:11] coreycb ok, you went back over and grabbed the new releases?

[19:02] do you need any special hardware to do this or can we reproduce on qemu? [19:02] probably hardware [19:02] fwiw, I did the upload earlier [19:03] I can't reproduce on qemu but it requires a host-side drop of the device [19:03] I'm getting access to a s390x instance with FCP devices to reproduce [19:03] we have that, but getting access to "re-enable" them is a challenge since it requires special privs [19:03] I also have an RT open for an internal system where we'd have the privs to do the reneable [19:04] that said, two paths: I'm looking at multpathd patches from upstream: 646e754853b123a075b4cede7d9ccf540e8c9b0c 7e00a100ed566f709a0e93a762101ad51dee1498 72ceb736edebfe4720ead34caa95be7d88e65dfa [19:04] which are around udev path discovery and timeouts [19:04] ok [19:04] which are present in the debian version where ibm doesn't see the issue [19:04] I already backported a whole lot of such paths [19:04] *patches [19:04] nice [19:04] lemme look at ubuntu15 then [19:04] * cyphermox looks [19:05] and see what you picked up versus what's in debian [19:05] don't bother, I was talking in general [19:05] ok [19:06] what I mean though is perhaps we should not worry too much about reproducing and just merge with Debian [19:06] cyphermox: +1 on that [19:06] the number of fixes since 0.5.0 is signficant; and while we have a lot of stuff we know the debian version is fully working for ibm on Z with FCP devices [19:08] ok [19:08] wanna try your hand at that merge?
