[04:43] <_jp> hey all. I'm dealing with the notorious stale NFS file handle problem. I can't unmount or remount. Is there any way to solve this without rebooting?
[04:44] <_jp> I've tried lazy unmount, and forcing
[04:45] <_jp> The NFS server had to be rebooted, but the share is available again.
[04:46] <_jp> Any way out of this?
[04:47] <cfhowlett> _jp ##linux might know
[04:47] <_jp> k
[05:12] <racecon> getting started on virtualization for a couple of headless servers running 14.04, would kvm or xen be the way to go?
[05:31] <andol> racecon: I'd go with KVM, both because of it having more momentum in general as well as it being better integrated in Ubuntu.
[05:35] <racecon> thanks for the input.  it seemed like kvm was somewhat preferred in some forum posts I read.
[06:47] <Guest92124> Hello.  I am looking for help in getting DNS working.  Everything is loading, loags are being written, no firewall to port 53.  When I tyr dig, it returns status: SERVFAIL
[06:47] <Guest92124> Oh and I am running LinuxMint
[07:17] <lordievader> Good morning.
[08:06] <ashd> morning world.  i have a system hang at this point - http://screencast.com/t/1PV6XFQFav - file system is clean - all packages are good but it will not complete the boot process 14.04 LTS
[08:11] <lordievader> ashd: Did you create a custom initrd?
[09:06] <ashd> lordievader: no, was completly out of the box with updates
[09:08] <ashd> lordievader: and thinking that soemthing was wrong i “apt-get install --reinstall initramfs-tools” - but is still broken
[09:09] <SierraAR> I'm looking for a web based file manager I can setup on ubuntu server 12.04, that should only have access to a specific folder and access files/folders as a specific user (The folders are in a users /home directory, not in /var/www/
[09:09] <lordievader> ashd: You could try recreating your initramfs, "sudo update-initramfs -u"
[09:09] <SierraAR> Also, if any ops are around, someone in this channel sent me a random PM with a link I'm not clicking when I joined
[09:09] <SierraAR> [02:08] <kikinii> show gratis (solo hooy) --> (Link removed so nobody clicks it)
[09:10] <ashd> SierraAR: I had that as well.. blocked and deleted
[09:11] <ashd> lordievader: i’ll give that a go - 48 hours and i am still no closer to getting a clean boot.
[09:11] <lordievader> ashd: Oh, do you have some kind of a special setup?
[09:12] <ashd> lordievader: well, is dedicated to virutalmin - it is in an ESXi container but apart from that a fresh install of 14.04 LTS
[09:12] <ashd> lordievader: well, fresh, two weeks old
[09:12] <lordievader> No raid or something? Uefi? That sort of thing?
[09:13] <ashd> lordievader: No raid, ESXi disks only, one disk LVM set up for /root and swap
[09:13] <ashd> lordievader: sda1 = boot….
[09:13] <ashd> lordievader: all pretty out of the box really
[09:13] <ashd> lordievader: it is in the init phase that it breaks.. but i am stuck getting some logging out of that.
[09:14] <lordievader> ashd: lvm2 is installed I take?
[09:14] <ashd> lordievader: well it was.. - and as i can work with the disks in rescue mode it is working i suppose.. i can boot in with break=init and housekeep etc, all the disks are clean and the packages up to date.
[09:15] <ashd> lordievader: i have not specifically looked at LVM yet, was looking at systemd - upstart - random
[09:16] <lordievader> Well lvm support needs to be in the initrd/initramfs.
[09:18] <ashd> lordievader: the system was booting fine untill the host had a crash on friday AM, lvm is in the initramfs as i can boot=init and work with the file systems etc
[09:18] <ashd> lordievader: or perhaps i should look into this.
[09:18] <lordievader> ashd: Have you checked the filesystems for errors?
[09:19] <ashd> lordievader: all clean - and all packages are good - i have re-installed upstart - systemd - and a few others all without issue
[09:19] <SierraAR> Ok, new problem.. I was having an odd error with webmin on my 12.04 server, so I went to uninstall and reinstall it... Suddenly, when I run 'sudo apt-get install webmin', it's telling me it's unable to locate package webmin. I'm tried running a sudo apt-get update, but no luck
[09:20] <ashd> SierraAR: grab the package from the webmin site and dpkg -i webmin.xxx
[09:21] <ashd> SierraAR http://sourceforge.net/projects/webadmin/files/webmin/1.690/webmin_1.690_all.deb/download?use_mirror=softlayer-ams
[09:21] <SierraAR> Right.. completely forgot it's not in the repositories. That through me off because apt-get remove worked xD
[09:22] <lordievader> !webmin
[09:22] <lordievader> SierraAR: ^
[09:22] <SierraAR> Wonder if that's related to why webmin was giving me invalid request errors
[09:23] <ashd> ubottu: when was this decision taken?
[09:24] <ashd> ubottu: i was only asking...
[09:24] <ashd> !virtualmin
[09:25] <lordievader> !ubottu
[09:26] <SierraAR> Hm.. Out of curiousity.. If I wanted to setup an interface on an ubuntu server I want to access through VNC, is that possible?
[09:26] <SierraAR> I.e. setting up a simple desktop environment with a vnc server, that starts on boot
[09:26] <lordievader> SierraAR: Yes it is possible, however it ain't recommended. VNC isn't very secure.
[09:27] <SierraAR> lordievader: If I'm using a realvnc license with encryption, and it only accepts tunnelled SSH connections (AKA localhost only)? I'm not actually sure if doing that makes anything more secure
[09:27] <ashd> SierraAR: put up a VPN and keep it inside that
[09:28] <SierraAR> Pretty much everything on my server only responds to localhost, and my SSH user only accepts a private key
[09:30] <lordievader> ashd: By the by, from the break=init busybox are you then able to continue the boot process?
[09:34] <ashd> lordievader: no, i can work with the system but when i exit out of it - it hangs
[09:35] <lordievader> Hmm, you where able to mount your disks right?
[09:35] <ashd> lordievader: yes, and check them, and after mounting proc and dev i can install uninstall using apt-get / aptitude etc.
[09:36] <lordievader> Pff, that is really strange...
[09:37] <ashd> lordievader: yes, and i would really like it not to be strange - i am about to ditch ubuntu for centos 7 for this application - if i cannot work out WTF is going on - how can i be sure it will not happen again.
[09:40] <ashd> lordievader: i actually suspect it is something simple, just need to get a handle on it.
[09:41] <lordievader> Heh, CentOS is even wierder :P
[09:42] <Guest92124> exit
[09:42] <Guest92124> quit
[09:44] <ashd> lordievader: eveyrhing is weird untill you understand it -
[09:45] <lordievader> !info initscripts
[09:46] <lordievader> ashd: Is ^ installed correctly? (Reading an old bug report, they mention that package)
[09:51] <ashd> lordievader: i everything checks out ok - BUT i will reinstall it now (i think that is one of the re-installs i ahve already done)
[09:54] <ashd> lordievader: apt-get update ran clean
[09:55] <ashd> lordievader: sudo dpkg --configure -a = clean
[09:56] <lordievader> ashd: sudo apt-get dist-upgrade?
[09:57] <ashd> lordievader: no dist-upgrade availabe for 14.04 LTS
[09:57] <ashd> lordievader: but i did run it anyway
[09:57] <ashd> lordievader: so initscripts is now —reinstalled
[09:59] <ashd> lordievader: exit from busybox gives me http://screencast.com/t/24rw4aIs
[09:59] <ashd> lordievader: will re-boot and see
[10:00] <ashd> lordievader: does not look any better.
[10:01] <ashd> will leave it for a while and see if there are any developments while i look up that last screencast
[10:03] <lordievader> ashd: Well it's different, different is sometimes better ;)
[10:04] <ashd> lordievader: yes, was different when exiting busybox.. but not in the normal boot.. BUT i thought selinux is replaced by apparmour in 14.04LTS
[10:04] <ashd> lordievader: i am looking into that now
[10:14] <ashd> lordievader: well re-installing apparmor did not do anything useful
[10:15] <lordievader> ashd: You don't run a custom kernel, right? Just the generic one?
[10:16] <ashd> lordievader: generic - and i have re-installed it too
[10:18] <lordievader> Hmm interesting on my machine the /sys/fs/selinux does not exist either.
[10:18] <ashd> lordievader: is 10.04?
[10:19] <ashd> lordievader: basically - i have been looking at this since friday AM - and i am nowhere nearer sorting it out.
[10:19] <lordievader> Ah, are you running 10.04?
[10:25] <ashd> lordievader: no 14.04 LTS
[10:32] <lordievader> ashd: Ah ok, running Trusty here too.
[10:33] <ashd> lordievader: have started installing centos in another container - if i cannot understand this - then i cannot trust it to be in production
[10:34] <lordievader> Well this shouldn't happen. I have never seen it to be honest.
[10:35] <ashd> lordievader: yep, i have never seen the, nor has anyone else i have spoken too.. there are some threads on the net about similar boot problems, but nothing seems to help or actually be relevenat to the problem.
[10:35] <lordievader> Reinstall of Trusty ain't an option?
[10:36] <ashd> lordievader: so it can happen again? there should not be an issue that cannot be fixed by the sysadmin for the machine - re-installing because i don’t understand is the microsoft way
[10:37] <ashd> lordievader: it will be on the same hardware - same software - basically virtualmin pro - so once i get sites going live i really don’t want this to happen again.  and given what the bot just said about webmin, which is what virtualmin is built on
[11:27] <ashd> !webmin
[11:48] <linuxthefish> hi, does ubuntu server have wifi utility in by default?
[11:48] <linuxthefish> like to configure wifi networks
[11:57] <lordievader> linuxthefish: On a Trusty vm of mine they seem to be available.
 show gratis (solo hooy) --> http://s422803032.mialojamiento.es/
[12:39] <linuxthefish> what is this?
[12:40] <lordievader> linuxthefish: A spam bot. Just ignore the bot.
[12:41] <linuxthefish> oh
[12:41] <linuxthefish> thanks though, ubuntu server time!
[13:25] <Maddeth> Hi guys been having a kernel panic: "kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)" it's on a VM, I have tried numerous backups, and different kernels, re-installing grub, /boot is not full, I have performed and apt-get autoremove but nothing appears to be working
[13:26] <Maddeth> I have also tried installing new over the top without formatting the original disk, it runs fine, but reboots with the same error
[13:27] <Maddeth> If it wasn't for the fact I have tried backups from 30 days ago, I would have pointed at the vmdk
[13:27] <Maddeth> but, I am at a loss
[13:27] <Maddeth> anyone have any experience, or idea as to what I can try next?
[13:28] <Maddeth> I have already replaced the server that died, but I really want to get to the bottom of this
[13:29] <lordievader> Maddeth: What kind of vm is it?
[13:29] <lordievader> KVM?
[13:30] <Maddeth> ESXi
[13:30] <Maddeth> lordievader: v7
[13:31] <lordievader> Does it use LVM?
[13:31] <Maddeth> No
[13:31] <Maddeth> lordievader: not through my choice ;)
[13:32] <ashd> Maddeth: create a new VM and use your existing disks
[13:32] <lordievader> The VM uses a standard Ubuntu kernel I take?
[13:32] <Maddeth> lordievader: yes
[13:32] <Maddeth> ashd: hmm, good shout, I will take a look
[13:33] <ashd> Maddeth: actually, install a minimal fresh and then you know it works
[13:33] <ashd> Maddeth: then swap out the vdisks
[13:37] <Maddeth> ashd: same issue (without doing a minimal fresh first)
[13:42] <Maddeth> taking a break, off on lunch for a sec :)
[13:43] <nerium> Have anyone here heard about a software called Linux_time_y_2?
[13:43] <nerium> My server has been "infected" with this file and is doing a ton of DNS requests against a server
[13:44] <nerium> Its being ran as the elasticsearch user and I'm not sure how it go into the system
[13:56] <dasjoe> nerium: this gives a good summary about what happened to your box and what to do now: http://www.gossamer-threads.com/lists/wiki/wikitech/482149
[13:57] <nerium> dasjoe: Awesome, thansk!
[14:27] <Maddeth> ashd: lordievader: Trying it on a different host now, see if that makes a difference
[16:25] <punkgeek> i need encodeing my php file in /var/www/html, what should i do? :-?
[16:26] <Patrickdk> what do you mean
[16:54] <psih0man> hello! I'm trying to start a LXC on an Ubuntu 14.04 host but it is giving me an error about the mounts and it won't start; the container was created with lxc-create -n container -f container.conf -B loop. here are the config, fstab and log files: http://dpaste.com/0V445J0
[16:54] <psih0man> what whould fstab contain in this case?
[19:34] <alison412> hi all. i am trying to upgrade using do-release-upgrade. i am over ssh and lost my connection. no worrries, it starts screen when it starts. except now it wont accept my user password. i am logged in as root right now but im not sure what to do without breaking it. help.
[23:00] <marshall> hey ubuntu
[23:01] <marshall> what's the easiest way to setup single-sign-on? I don't want to have to setup all my users, groups and home directories on every machine
[23:03] <jrwren> copy your passwd adn show files around?  :)
[23:03] <jrwren> its not a good solutino, but its the easiest.
[23:03] <marshall> i've used LDAP and, it's anything but it's pretty precarious
[23:04] <marshall> every apt-get upgrade on the client breaks ldap auth
[23:07] <Patrickdk> it depends what you want sign-on for
[23:07] <Patrickdk> and what you need to support
[23:07] <Patrickdk> personally, I'm using just about everything :)
[23:07] <Patrickdk> ldap, radius, pam
[23:07] <Patrickdk> between those, pretty much have everything covered
[23:08] <Patrickdk> you could go more modern, and to saml
[23:23] <tjbenator0> So when I set "mailbox_command = /usr/lib/dovecot/deliver" in postfix I get an error
[23:23] <tjbenator0> which says there is a configuration error with dovecot. When I use "dovecot -n" it returns no errors
[23:25] <Patrickdk> that is to be expected
[23:26] <Patrickdk> if you switch to lmtp instead, you won't have issues
[23:44] <marshall> Patrickdk: i think i want to give saml a try
[23:50] <tjbenator0> I found some instructions here: http://wiki2.dovecot.org/HowTo/PostfixDovecotLMTP... Tried it and now I'm getting Undeliverable email stating the user doesn't exist
[23:54] <tjbenator0> Oh wait, I think i fixed it ;D
