TangurinHi! When my applikation is creating a row in the database it works fine, but when it edit a row in the database it crashes, I use Laravel on Ubuntu 14. Do you know why?00:08
ldchello!00:38
ldcis it normal to have .sudo_as_admin_successful in my home00:38
ldcsince 15.04?00:39
RevertToTypedoes .xinit not work in a home directory anymore in 15.04?00:40
RevertToType.xinitrc rather same question though00:42
tarpmanldc: yes, it's normal00:49
tarpmanRevertToType: that depends very much on how you log in and how your session is launched00:50
RevertToTypenvm was too zoned to notice00:50
ldcok thanks00:50
RevertToTypetarpman:  i figured it out... stupid oversight on my part.00:50

tanukiWhy does my kernel update every week?01:24
sarnoldthe kernel team works on roughly a three-week cadence where they integrate fixes, build, test, and deploy01:25
tanukiI just wasn't expecting to be told to reboot my server so frequently, especially since it's running Trusty01:25
sarnoldand some security issues are severe enough that waiting three or four weeks before deploying the fix would be irresponsible, so they get 'emergency kernels', prepared outside the cadence01:25
tanukiMakes sense, I guess01:26
sarnoldtanuki: you can investigate oracle's ksplice service; they have a hot-patch mechanism that reduces the needs for reboots while still deploying some fixes01:27
sarnoldI have no idea what they charge for this service, but if downtime is expensive, it might be enough to pay for itself01:27
tanukisarnold: Nah, not expensive at all. Just annoying.01:28
tanukiIt's a home server.01:28
sarnoldsuse and red hat are working on merging their hot-patching mechanisms together, and then merging them into the kernel; it's possible that some updates in the future from ubuntu will be prepared in a manner to take advantage of it, but that feels like perhaps two years or more in the future...01:28
sarnold*nod*01:28
sarnoldtanuki: don't tell anyone but I go months between reboots01:28
sarnoldonce in a while I'll see a fix that justifies a reboot..01:29
OerHeksas of kernel 4.x we don't need to reboot anymore, with hot patching.01:29
OerHekslike ksplice01:30
sarnoldOerHeks: am I out of date again? has that already been merged?01:30
sarnoldtanuki: wow, it actually looks like oracle may provide ksplice for free to ubuntu and fedora users http://www.ksplice.com/try/desktop01:31
OerHeksYes, sarnold, http://www.zdnet.com/article/no-reboot-patching-comes-to-linux-4-0/ known for some time now, waiting for wily01:31
sarnoldOerHeks: woo :)01:32

jamespagecoreycb, zul: I dropped init-system-helpers from liberty-staging - I could see no good reason for the backport - and it foobars everything that uses dh-systemd afterwards as its not compat with 14.0408:21
siebjee╦ťnnjjk08:29
gnuoyjamespage, the ceph radosgw init.d script is broken on trusty if you use restart. It stops the service but doesn't start it up again. I would say that that is an SRU candidate? I cannot reproduce on wily, although on wily systemd is falling back to the init script the issue doesn't appear. I assume it's ok to target a SRU fix directly at trusty since it's not relevant   in the current development release?09:38
jamespagegnuoy, yes that's fine09:46

VoyageIs there a GUI tool to do torture test and measure cpu/memory performance ?12:02
tewardVoyage: this is the server channel, probably not going to get the best help for that here (ubuntu server installs typically run headless, i.e. no gui)12:03
lordievaderVoyage: Guis and servers.... What's wrong with stress?12:04
Voyageok. tell about no gui12:04
coreycbjamespage, zul: can one of you rebuild openstack-trove when you get a chance?12:04

jpdssb_9: Unplug from the internet13:06

jpdsFind out how they got in, go through the logs13:06
patdk-wkwell, unplug the power from it13:06
patdk-wkreplace it with a new server13:06
patdk-wkthen look into how they compromised it13:06
patdk-wkfix it issues on your current servers13:07
patdk-wkshred compromised server13:07
sb_9it was unplugged from internet. just i have digging into cause that compromised the system.13:08
jpdssb_9: Found and fix the cause, reinstall the server from 013:08
sb_9patdk-wk: i have gone through log's and new logins, open ports, any unknown process.13:08
patdk-wkit's rare for you to find a compromise that way13:09
jpdssb_9: Also, consider putting an outgoing firewall on the box and block all unneeded outbound access13:09
patdk-wknormally it's very very simple, vaunerable cgi13:09
sb_9patdk-wk: Good Idea. Agree we have rare situations to identify the cause, but i need more suggestions on this.13:12
sb_9can i have quick example of blocking all unneeded outbound access with firewall.13:14
patdk-wkno13:14
patdk-wkyou need to be more specific13:14
sb_9patdk-wk: how can i analyse the cause.  if it is with any cgi script?13:16
patdk-wkask your cgi script13:16
jpdssb_9: We don't know what your server's running13:18
sb_9patdk-wk: understood.13:18
jpdssb_9: And if you don't know what it's running... you shouldn't be running it13:18
sb_9jpds: i will check it.13:18
sb_9jpds: okay. how can i idenitfy any offending files that was created in a specific time period?13:20
jpdssb_9: With find command and the mtime option13:20
sb_9jpds: thanks.13:20
patdk-wkjpds, no13:23
patdk-wkanyone can change the mtime of a file13:23
patdk-wkso that is not accurate13:23
patdk-wkand it wont tell you if it's is offending or not13:23
patdk-wkI have found ext to be horrible at this13:24
jpdspatdk-wk: http://is.gd/Emzzd513:24
patdk-wkpeople can't change the mtime?13:24
sysrexguys, is there anyway to see when a package in ubuntu trusty will be upgraded?13:24
jpdssysrex: upgraded how?13:24
patdk-wksysrex, sometime in the next 3.5years, or not at all13:25
jpdspatdk-wk: That's what I picture when people just say "no"13:25
patdk-wkyou should look at creation time :)13:25
patdk-wkand to get the creation time from ext is rather annoying13:25
jpdspatdk-wk: mtime might not be super accurate, but it's a good start13:25
jpdspatdk-wk: What if they didn't create a file?13:25
patdk-wkyes, I have found it to be about 50% accurate myself, using mtime13:26
patdk-wkjpds, you should never use just one thing :)13:26
patdk-wkbut most of the time they download a zip/tar/...13:26
patdk-wkand unpack it13:26
patdk-wkthe unpack normally restores the mtime13:26
patdk-wkyes, check mtime, but don't depend on it at all13:27

cyphermoxroaksoax: should still get fixed though, no?14:33
cyphermoxit would be really great if someone could spend the time to port it to use wget instead of curl, since that would mean not carrying extra delta on curl to ship a udeb.14:34

sarnoldI think it just starts sessions, it shouldn't place much requirement on what gets executed afterwards23:32
