[00:09] <erichammond> mconigliaro: Hostnames on an Ubuntu EC2 instances can be changed the same was as a hostname on any normal Ubuntu server and it's fine to do so.
[00:10] <erichammond> er, "same way"
[00:10] <mconigliaro> erichammond: using the hostname command?
[00:10] <mconigliaro> ive tried that
[00:10] <mconigliaro> even though i get what i want in the bash prompt, hostname -f always returns the amazon hostname
[00:11] <mconigliaro> /etc/hostname seems to be totally ignored
[00:12] <erichammond> mconigliaro: Yep, there are a few things you need to update depending on what software you have installed. "hostname" command; /etc/hostname; /etc/hosts; /etc/mailname; /etc/postfix/main.cf; ...
[00:13] <erichammond> You might need to restart various services as well
[00:13] <erichammond> The point is, however, that it's no different from a normal Ubuntu server.
[00:15] <mconigliaro> i must really be doing something stupid
[00:15] <mconigliaro> in the past, i just updated /etc/hostname, rebooted, and that was that
[00:18] <smoser> mconigliaro, well that would work

[00:23] <sabgenton> I want to push windows printer drivers where is the default samba share location to put them
[00:24] <sabgenton>  /usr/share/cups/drv/ ?
[00:35] <erichammond> smoser: wow, I had assumed that bug was important enough to fix and stopped paying attention to it.  Can we get it corrected in the next Hardy and Karmic?  Changing the hostname of a server can break the functionality of that server.
[00:35] <iclebyte> I'm having trouble building the postfix-2.5.1 sources after applying the VDA quota patch. The issue is actually at the dpkg-buildpackage stage, I get "dpkg-buildpackage: failure: tail of debian/changelog gave error exit status 1". Any suggestions as to a solution? I've been trying to resolve this for hours..
[00:47] <mconigliaro> erichammond, smoser: yes, that bug is what's messing me up. if i change the hostname in rc.local, it works fine
[00:47] <mconigliaro> although services already started are using the ec2 hostname
[00:49] <mconigliaro> my workaround is to create a service called ec2-init-hostname that runs immediately after ec2-init and sets the hostname according to what's in /etc/hostname

[03:15] <Roxyhart0> hi someone has installed heimdal ?
[03:34] <Roxyhart0> hi, somebody know how i can know wich packages i got installed i want take off anything relative to kerberos and heimdal
[03:52] <Tohsh> Can anyone assist me in assigning a users traffic to go through a certain IP address through iptables?
[05:47] <Roxyhart0> hi iam trying to change users password and i got this error: passwd: Authentication information cannot be recovered
[05:47] <Roxyhart0> somebody know about this problem?
[05:48] <genii> Are you using some remote auth method like a radius server?
[05:48] <Roxyhart0> no, i just instaled ldap and take off kerberos
[05:48] <Roxyhart0> but my user is unix user
[06:16] <Roxyhart0> how i restart pam?
[06:49] <mufasis> i have a quick question
[06:49] <mufasis> im taking a class on php and i have a spare server a buddy gave me and i cant decide if i want to run server 2003 or some type of linux to learn php with
[06:49] <mufasis> lamp/wamp
[06:50] <mufasis> any suggestions
[06:57] <qman__> PHP works best in a unixy environment
[06:57] <mufasis> why is that?
[06:57] <qman__> that's what it was designed on
[06:58] <qman__> apache on windows is very difficult to secure
[06:58] <qman__> since it tends to run as administrator
[06:58] <qman__> in ubuntu, LAMP is secure by default
[06:59] <qman__> also, few situations in the 'real world' will use PHP on windows
[06:59] <qman__> because windows is expensive, you only use it when you need it
[07:00] <mufasis> that makes sense
[07:00] <mufasis> how hard is lamp to setup and use on ubuntu?
[07:00] <mufasis> see the thing is my buddy gave me this old proliant dl320 g2 server
[07:00] <qman__> as hard as checking a box during setup
[07:00] <mufasis> lol
[07:01] <qman__> or, post-install, 'sudo tasksel install lamp'
[07:02] <mufasis> just another quick question
[07:03] <mufasis> in linux how hard is it to setup vpn or an ftp server
[07:03] <mufasis> im not a linux pro but i can get by
[07:03] <qman__> VPN, takes a little bit of work, but not too difficult
[07:03] <qman__> you have to set up a PKI with the built in scripts, generate a CA cert and client certs
[07:03] <qman__> and set up the base config
[07:03] <qman__> FTP should be avoided if at all possible, in favor of SFTP
[07:04] <qman__> FTP is insecure by design and just generally a pain to work with
[07:04] <qman__> while SFTP is built into the openssh server, and is easy to configure securely in recent versions
[07:05] <Siph0n> mufasis, I just set up an sftp server in a hour or two
[07:05] <Siph0n> pretty easily, and even included the chroot feature
[07:05] <Siph0n> and im a pretty newbie to it
[07:06] <mufasis> the server is at my family house on a pretty fast home lan and im a student so i would only be able to work on it through putty or something similar....im taking some programming classes so i need to have lamp/wamp but i also need a way to upload and download files remotely ie ftp/vpn
[07:07] <mufasis> besides initial setup which i would do right there with the server
[07:07] <qman__> sftp is the way to go, you can use the command line apps with putty or get something fancier like winscp or filezilla
[07:08] <qman__> if you don't need jails or accounts for other people, sftp is automatically set up by installing openssh
[07:08] <qman__> another check box during setup
[07:12] <qman__> the only thing that isn't already dealt with on a default install is bots attempting to brute force your SSH server
[07:12] <qman__> if you have a reasonably quick machine and secured user accounts, it won't matter
[07:12] <qman__> if you care about it, you can set up some iptables rules to slow them down
[07:20] <mufasis> thank you for your help qman
[07:20] <qman__> no problem
[07:47] <mufasis> does 9.10 ubuntu server come with a gui
[07:49] <jmarsden> mufasis: No.
[07:50] <sherringham> mufasis: in general, servers run without a GUI/X - a waste of space. Use the comand-line.If you want though, you can stick a desktop on it ..
[07:51] <mufasis> oh im just wondering cause like i said before im taking a php programming class and i cant decide between server 2003 and linux. can you type all the code in the command line and see a working version of the page?
[07:52] <jmarsden> See it in a browser on your client PC, of course.  See it (in full graphical glory) on a text mode screen, no.
[07:52] <mufasis> i think it wouldbe difficult to program a webpage in php through a cli no?
[07:53] <jmarsden> No, it's trivial.  echo -ne '<?php\nphpinfo();\n?>\n" >somefile.php
[07:53] <jmarsden> Bingo.
[07:53] <jmarsden> I didn't even need a text editor :)
[07:54] <jmarsden> Well, I mismatched my quotes... but apart from that :)
[07:54] <mufasis> well im sure with your experience not a lot of things with linux seem hard but im semi new =/
[07:55] <jmarsden> Is the server your only machine?  WOuldn't you be writing code from the comfort of a GUI desktop or laptop anyway?
[07:55] <jmarsden> Why does the *server* need a GUI?
[07:56] <jmarsden> PHP is a programming language.  It is stored as text.  You can therefore create it in a text editor, which can be done in a GUI or using a text mode screen.
[07:56] <sherringham> mufasis: normally, you develop on a different system (with a GUI) then cp/scp/rsync your site/files to the server.
[07:57] <sherringham> mufasis: but if you don't have another system, or want to test/play on the server itself and you are uncomfortable with command-line only - add a GUI! No problem.
[07:57] <mufasis> yeah makes sense, ill be back in a few i have to attend to something
[07:58] <mufasis> no i understand
[07:58] <mufasis> but a friend of mine gave me an old proliant dl320 g2 server
[07:58] <jmarsden> So use that as a server, but create web pages on your existing workstation (which already has a GUI).
[07:59] <genii> then scp or so
[07:59] <mufasis> yes i was just trying to figure out if i should use linux or server 2003, considering im better on windows then i am on linux but i can get by
[07:59] <mufasis> ill brb
[08:12] <qman__> using a GUI won't give you any advantages, the code is still written in text and the software is still configured with the same files
[08:13] <qman__> there is no effective difference between running a GUI with a terminal and web browser open on the server, and running putty and your web browser on your client
[08:25] <Callum__> awwwwww
[08:25] <mufasis> back sry guys
[08:26] <Callum__> the SCSI data cable in my server is being stupid, DAMN IT
[08:26] <mufasis> the server i have is behind a router on 15mbps cable line
[08:26] <mufasis> when running the lamp
[08:26] <Callum__> I can't get the spare one I have at work until tomorrow...
[08:27] <mufasis> will the webpage be visible to everyone to see?
[08:27] <mufasis> i dont want that, i just want a running lamp server for development
[08:27] <qman__> mufasis, it will only be visible if you forward port 80
[08:27] <qman__> also, in order to get ssh access from the internet, you would need to forward port 22
[08:28] <Callum__> mufasis: yeah, on a connection that fast your server should be visible to the Internet, of course after forwarding your ports like qman__ said
[08:28] <Callum__> you will also need to forward port 443 for HTTPS
[08:29] <mufasis> for running a website dont i need to register something with someone to have it online?
[08:29] <qman__> no
[08:29] <qman__> if you forward the ports, it will be available at your IP address
[08:29] <qman__> you can find that out by browsing to a site like whatismyip.com
[08:30] <qman__> if you want a domain name, you will have to register one
[08:30] <qman__> you can also opt for free dynamic DNS through services like dyndns.com and afraid.org
[08:31] <qman__> but that's all optional, the site would be available at your IP regardless
[08:31] <mufasis> ok so if i want to test my code i would just navigate to my ip address with the correct ports forwarded through my router correct?
[08:31] <qman__> yes
[08:31] <mufasis> if i wanted an actual website name i would have to register it through a dynamic dns service?
[08:32] <qman__> yes, either register a paid domain, or get a free dynamic DNS subdomain
[08:32] <mufasis> now if i want to work on my server remotely i can use putty with port forwarding correct?
[08:32] <mufasis> with putty though i cant upload and download from the server....
[08:32] <mufasis> how would i do that
[08:33] <qman__> you can if you forward port 22
[08:33] <qman__> the putty suite includes pscp and psftp, which allow you to transfer files
[08:33] <qman__> but you can get a graphical SFTP client like winscp or filezilla, too
[08:36] <mufasis> what kind of maintenence or setup do i need to do when installing ubuntu server if i decide to go this route, i know eventually i will be working with linux but my semester is coming up quick and i need someone i can setup problem free very quickly
[08:36] <Callum__> qman__: there is http://xname.org/ a free domain name registrar but you have to be running your own BIND server to use it
[08:36] <qman__> mufasis, the install is as simple as following a menu guide, and maintenance is zero if you enable automatic updates
[08:37] <mufasis> no ive installed ubuntu before but i dont know which packages i need and what does what
[08:38] <qman__> my current record from disc in hand to production web server is ten minutes flat
[08:38] <mufasis> also this server needs these drivers from hp because the fans are so fuckin loud without them, can i send you a link to see if these owuld work?
[08:38] <qman__> you simply need to check LAMP and openSSH when prompted
[08:39] <qman__> go ahead and paste the link
[08:40] <qman__> I wouldn't be surprised if the drivers are included, given the how old the hardware is
[08:42] <mufasis> http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=15351&prodSeriesId=3929672&prodNameId=3929673&swEnvOID=4085&swLang=13&mode=2&taskId=135&swItem=MTX-ee4cf438fc6a4fbb875baad8ed
[08:42] <Roxyhart0> sombodey know what is nscd ?
[08:42] <mufasis> no ive installed ubuntu before and i needed these certain drivers
[08:42] <mufasis> i have them on my pc but i think these are updated
[08:43] <qman__> if you've tested them before, then sure
[08:43] <mufasis> it might be these
[08:43] <mufasis> http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=T2811AA
[08:43] <qman__> just copy the file over to the server, and 'sudo dpkg -i filename.dpkg'
[08:43] <mufasis> it says these are for sarge 3.1 will they still work for 9.10?
[08:44] <qman__> maybe, maybe not
[08:44] <qman__> the first link says for ubuntu 9.10, so I'm going to guess it's newer
[08:44] <qman__> january 2010
[08:45] <qman__> I'd go with that one
[08:46] <qman__> packages for debian aren't necessarily incompatible with ubuntu, but they may rely on packages or package versions that ubuntu doesn't have
[08:46] <qman__> so it's something that you have to test and play with
[08:47] <qman__> especially when you're dealing with drivers
[08:50] <mufasis> on the second link i sent those are the ones i have used before and i know theyre dependencies so i know it works
[08:50] <mufasis> just one more question with ubuntu server edition
[08:51] <mufasis> what is the best way to partition the drive
[08:51] <mufasis> i have 80gb to work with
[08:52] <qman__> in your case, one big partition should be fine
[08:52] <qman__> the 'guided (use entire disk)' option
[08:53] <qman__> other partitioning schemes are more important when you have more disks or want to keep your personal data separated
[08:53] <qman__> but for a simple development web server, it's not necessary
[08:55] <Roxyhart0> hi i am trying to set the smbpasswd for root and i got this error:Failed to find entry for user root.
[08:55] <Roxyhart0> anybody know what could be the error?
[08:58] <qman__> Roxyhart0, that's _really_ not a good idea, but to answer your question, you must use smbpasswd -a to create a new one
[08:59] <Roxyhart0> yes
[08:59] <mufasis> doesnt the guided partition option make several partitions though? one for swap / /home etc?
[09:00] <qman__> mufasis, no, just a / and swap
[09:01] <Roxyhart0> my questio is when i try to acces with ssh to my server it is taking long time and i got a a error : ssh root@rx.au
[09:01] <Roxyhart0> root@rx.au's password:
[09:01] <Roxyhart0> Failed to add entry for user root.
[09:01] <qman__> Roxyhart0, that's because root is disabled by default for security reasons
[09:01] <qman__> use a normal user, then use sudo to perform actions as root
[09:02] <Roxyhart0> but  i did before
[09:03] <Roxyhart0> i dont know why t changed
[09:03] <Roxyhart0> i dont like use sudo
[09:03] <Roxyhart0> i need to repeat the password many times
[09:04] <qman__> if you need to do a lot of things as root, use sudo -i
[09:05] <Roxyhart0> i did, i access with my username and still the same error: Failed to add entry for user rosa.
[09:07] <qman__> does smbpasswd also fail without -a?
[09:07] <qman__> (for rosa)
[09:09] <qman__> -a is only needed when a user does not already have an smbpasswd set
[09:09] <mufasis> thank you qman ur awesome
[09:10] <mufasis> i have another question how does remote file transfer and access work when im not on the same lan as the server using putty?
[09:10] <qman__> mufasis, just forward port 22 on your router to the server, then connect putty to your external IP
[09:15] <qman__> oh, also, thanks for the link to those drivers, I have an old proliant I haven't been using because it's so loud
[09:15] <Roxyhart0> sorry qman_ yes also fail when i try to inslude in samba
[09:16] <qman__> Roxyhart0, there must be something wrong in the samba configuration then, probably in the authentication backend setting
[09:16] <qman__> I don't know enough about it to troubleshoot more than that
[09:17] <Roxyhart0> thanks np
[09:19] <mufasis> lol np

[19:31] <JohnA> Dumb question, but how do I obtain and update my 9.04 or 9.10 server system - runs headless.
[19:31] <JohnA> 2nd ?, how can I get it to automatically restart after a crash?
[19:32] <guntbert> JohnA: 1) use ssh, 2) should be a bios setting (if you are talking about power failure)
[19:36] <JohnA> no looks like a kernel crash, ups log show no distrubance. the system just stops working with a v long series of what llok like diag messages on terminal
[19:37] <guntbert> JohnA: then I'd next assume a harware issue (heat, memory,...)
[19:42] <JohnA> it doesn't look like that, iy certainly is not heat, system runs open frame, HW diags don't show anything so I am assuming SW. sys is lightly loaded - postfix, dovecot and ancillary SW
[19:45] <JohnA> I wonder if I am missing some critical update, that why I asked about updates - how to for server 9.10 i tried apt-get but kept getting a error -1 says some packages not configured but these pkgs are not installed
[19:45] <guntbert> JohnA: check the memory
[19:45] <JohnA> ran memeory diags - nothing
[19:46] <guntbert> JohnA: did you run them through? the tests 1-5 are only for the worst cases
[19:47] <stas> hi guys, can somebody help me, how can I change how ubuntu sees the /dev/sdX drives
[19:47] <stas> I got a usb drive that boots as /dev/sda, and I want it /dev/sdc for example
[19:48] <guntbert> stas: you cannot - as far as I know
[19:49] <stas> guntbert: the drive has netboot kernel, i can remove the drive after its loaded, again no?
[19:49] <JohnA> guntbert: I wasn't running the linux diags was running some HW stuff from the electro lab, much more effective than the stnd stuuf
[19:50] <guntbert> JohnA: then I don't know
[19:50] <JohnA> ? is how can I get Linux to auto restart on crash
[19:50] <guntbert> stas: but the assingment is a kernel thing
[19:51] <stas> guntbert: so I cant make a "rescan" when I want one... ?!
[19:51] <guntbert> stas: not to my knowledge
[19:51] <guntbert> but that is limited :)
[19:51] <stas> guntbert: oky, thank you
[19:55] <stas> guntbert: actually i got an idea and it worked, I udevinfo -a -p /sys/block/mysda | grep -i drivers
[19:56] <stas> modprobe -r the driver
[19:56] <stas> and modprobe it back

[20:02] <enherit> www-data is used to run the apache process. I want to create a user just for running a process
[20:03] <guntbert> enherit: www-data *has* a homedir set
[20:04] <enherit> hmm. I think what I want is "a system user"
[20:05] <enherit> what are "system user" good for?
[20:06] <sherringham> See: man adduser (you probably don't need a "system" user i.e. id < 1000)
[20:06] <enherit> thanks.
[20:55] <MTecknology> I'm going to install xen on my server
[20:55] <MTecknology> anybody want to help me?
[20:55] <lifeless> nope
[20:55] <lifeless> kvm is win
[20:55] <MTecknology> :P
[20:55] <MTecknology> kvm for a server?
[20:55] <MTecknology> !kvm
[20:57] <MTecknology> lifeless: how hard is it to learn to setup a vm in say an hour or two?
[20:57] <lifeless> depends
[20:58] <lifeless> can be a few minutes if what you want is already doc'd
[20:58] <MTecknology> lifeless: probably is - um.. where are vm images normally stored?
[20:58] <MTecknology> I'm partitioning the drive right now
[21:01] <lifeless> whereever you like ? :)
[21:01] <lifeless> read the KVM docs, they are pretty good
[21:01] <MTecknology> alrighty - I'll just make /virt then :)
[21:02] <lifeless> if this machine is also a DHCP & DNS server, I would not try putting UEC on it unless you're up for debugging the last bits of the single physical machine topology
[21:02] <lifeless> kvm itself should be trivial (again -see https://help.ubuntu.com/community/KVM - really)
[21:03] <MTecknology> yup - I'm there
[21:03] <MTecknology> I like the kvm virt-viewer ssh+
[21:04] <MTecknology> qemu+ssh*
[21:06] <MTecknology> I mentioned using vmware for it but then I remembered how ugly vmware is on a system. We have a system with 8GB RAM and I'm pretty excited abotu it
[21:07] <chrisboom> hey guys, trying to get BackupPC installed on ubuntu server 9.10
[21:07] <chrisboom> getting told that 2010-02-13 20:43:15 $Conf{NmbLookupPath} = '/usr/bin/nmblookup' is not a valid executable program
[21:07] <chrisboom> but i have samba installed
[21:10] <lifeless> do you have /usr/bin/nmblookup
[21:12] <MTecknology> When you install a server you can choose cloud cluster or cloud node; how does a cluster work? can you have mysql sitting across multiple servers with that?
[21:13] <lifeless> cloud cluster is UEC; cloud node is a UEC node controller (which runs kvm instances for you)
[21:13] <lifeless> do you have existing network infrastructure
[21:14] <lifeless> like DHCP and DNS
[21:14] <MTecknology> no
[21:14] <MTecknology> we're not big enough to support that yet
[21:14] <MTecknology> so the node is used to admin the cluster?
[21:15] <lifeless> no
[21:15] <lifeless> 'cloud node' is a member in the cluster
[21:15] <MTecknology> I'm just trying to understand how it works - I want to setup some VM's in virtualbox and figure out what this stuff really is
[21:15] <lifeless> 'cloud cluster' is the controller
[21:15] <MTecknology> oh
[21:15] <lifeless> if you are not planning on using UEC, then don't choose either of those things
[21:15] <lifeless> you can use kvm without UEC
[21:16] <chrisboom_> lifeless: when i look it up, it tells me its not there
[21:16] <chrisboom_> so its not installed
[21:16] <chrisboom_> but i cant seem to work out how to add it
[21:16] <lifeless> you haven't installed the package it is in
[21:17] <chrisboom_> i think its part of samba
[21:17] <chrisboom_> which is defo installed
[21:17] <MTecknology> lifeless: I have a sinlge desktop I bought today that will function as our best server. When we get to the point of moving into a datacenter I want to know what's going on
[21:17] <lifeless> MTecknology: UEC is very nice, but a little temperamental on a single machine - I set one up last week on my home games machine. Doing it with that machine also hosting DHCP and DNS might be difficult
[21:18] <MTecknology> lifeless: I'm only goingt o use kvm on this - I'm just trying to understand cloud computing
[21:19] <lifeless> oh
[21:19] <MTecknology> can you have mysql installed on the systems and pretty much have it replicated everywhere?
[21:19] <lifeless> so UEC supplies an EC2-like system
[21:19] <lifeless> which means
[21:19] <MTecknology> or do you just have virtual machines that can be spread across multiple systems?
[21:19] <MTecknology> I never understood EC-2 either :P
[21:19] <lifeless> you have virtual machine templates
[21:19] <lifeless> called 'machine images'
[21:20] <lifeless> they get started on machines when you issue an API call
[21:20] <lifeless> and stopped likewise
[21:20] <lifeless> some basic firewall rules can be deployed at the same time
[21:20] <lifeless> and there is an API for managing stored content (in S3 - called  walrus in UEC)
[21:21] <lifeless> thats about the size of it
[21:22] <MTecknology> so it's a lot like installing kvm on multiple systems with the ability to control all VM's from one system and some firewall rules into the systems?
[21:22] <lifeless> yes
[21:23] <MTecknology> so there's not really any redundancy involved either?
[21:23] <lifeless> when a template is started it gets given an ip from a range you allocate the cluster, an ssh key (for the user starting it) copied into it
[21:23] <lifeless> MTecknology: depends on your definition of redundancy
[21:23] <lifeless> you can buy 10 machines when you need the capacity of 8
[21:24] <lifeless> and if one blows up, restart the vm's that were on it and keep going
[21:24] <MTecknology> ok
[21:24] <MTecknology> thanks :D
[21:24] <lifeless> the vm's get no persistent storage on the machine they are running on
[21:24] <MTecknology> I think that clears things up a whole lot for me :D
[21:25] <MTecknology> is it possible to have one server running on two systems?
[21:25] <lifeless> no
[21:25] <lifeless> or rather yes
[21:25] <lifeless> :)
[21:25] <lifeless> you can start the same machine image many many times
[21:25] <lifeless> so if you have a MI that runs mysql in cluster mode, with an appropriate autoconfig as it comes online, then you can run that MI 10 times
[21:26] <MTecknology> nifty
[21:26] <lifeless> and size the machine type such that its unlikely to end up with two instances on the same node controller
[21:26] <lifeless> of course then you need backend storage that is fast and reliably like lusterfs/cephfs etc
[21:26] <MTecknology> I'm installing on ext4
[21:26] <lifeless> or you need an S3 mysql storage engine
[21:27] <lifeless> MTecknology: nothing to do with what you're installing on
[21:27] <MTecknology> ok
[21:27] <lifeless> when you install you are creating a substrate
[21:27] <lifeless> its the foundations, nothing more
[21:28] <lifeless> what else, oh, highly available clusters. I don't think that UEC itself is redundant
[21:28] <chrisboom> so should there be an nmblookup AND an nmblookup.samba3 file?
[21:29] <lifeless> rather you're able to create two seperate UEC clusters with disjoint resources, and configure your app to run in both simultaneously (often needs app development to enable this)
[21:32] <MTecknology> lifeless: so two whole separate clsuters, then you setup the app so it runs in both systems simultaneously.... does mysql/apache support that?
[21:33] <sherringham> chrisboom: sudo apt get install samba-common-bin
[21:33] <sherringham> s/apt get/apt-get/
[21:33] <lifeless> MTecknology: 'often needs app development' ;)
[21:34] <MTecknology> lifeless: alrighty - thanks :D
[21:34] <MTecknology> lifeless: I love how well you explain your vast knowledge
[21:34] <lifeless> there is a big debate at the moment
[21:34] <lifeless> on whether folk want 'reliable clusters' or 'cheap to deploy lots of clusters'
[21:35] <lifeless> k, gotta run
[21:36] <MTecknology> lifeless: I'm all for the reliable
[21:59] <Zajjko1> I've managed to put my two main users on my server in /bin/false and as it turns out, for some unexplainable reason, my admin-user is not part of sudoers. These are the three users on the server. Is there any hope at all, without complete reinstallation?
[22:00] <guntbert> Zajjko1: I think recovery system is available in server too
[22:00] <Zajjko1> How do I access it? Would I need "sudo" to to so?
[22:00] <Zajjko1> to do
[22:01] <guntbert> Zajjko1: if I remember correctly you are dropped to a root console
[22:02] <Zajjko1> Right on.
[22:03] <Zajjko1> Hold on, though. By default in ubuntu server, root has no password and does no allow login
[22:04] <Zajjko1> Come to think of it, that is by default in ubuntu overall
[22:06] <guntbert> Zajjko1: should be no problem in recovery mode
[22:08] <guntbert> Zajjko1: works as I said: you get a menu, choose net root and get a root console
[22:13] <Zajjko1> guntbert: Ahh ok. So would I access it from the installed OS or via the install-CD?
[22:14] <Zajjko1> guntbert: rather, How do I access it? : )
[22:14] <lifeless> MTecknology: well reliable costs more than cheap redundant, is the argument. bye for now.
[22:15] <guntbert> Zajjko1: you boot from the HD, and press <shift> until the grub menu appears, there you select recovery mode
[22:16] <Zajjko1> Thank you, guntbert. Will try that
[22:16] <guntbert> Zajjko1: be sure to press <shift> early enough
[23:11] <MTecknology> !rl
[23:16] <Roxyhart0> Hi I am setting my ldap according how to and I dont undestand why is necesary this entry: ldap idmap suffix = ou=Idmap
[23:16] <Roxyhart0> My current ldap data doen't have this entry. Domebody know if is necesary to create? why?
