| 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. | 00:09 |
| 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 | 00:10 |
| mconigliaro | /etc/hostname seems to be totally ignored | 00:11 |
| 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; ... | 00:12 |
| 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. | 00:13 |
| mconigliaro | i must really be doing something stupid | 00:15 |
| mconigliaro | in the past, i just updated /etc/hostname, rebooted, and that was that | 00:15 |
| smoser | mconigliaro, well that would work | 00:18 |
| smoser | but ec2init is fighting you | 00:18 |

| sabgenton | I want to push windows printer drivers where is the default samba share location to put them | 00:23 |
| sabgenton | /usr/share/cups/drv/ ? | 00:24 |
| 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.. | 00:35 |
| 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 | 00:47 |
| 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 | 00:49 |

| 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 | 06:49 |
| mufasis | any suggestions | 06:50 |
| qman__ | PHP works best in a unixy environment | 06:57 |
| mufasis | why is that? | 06:57 |
| qman__ | that's what it was designed on | 06:57 |
| 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 | 06:58 |
| 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 | 06:59 |
| 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 | 07:00 |
| qman__ | or, post-install, 'sudo tasksel install lamp' | 07:01 |
| mufasis | just another quick question | 07:02 |
| 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 | 07:03 |
| 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 | 07:04 |
| 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 | 07:05 |
| 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 | 07:06 |
| 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 | 07:07 |
| 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 | 07:08 |
| 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 | 07:12 |
| mufasis | thank you for your help qman | 07:20 |
| qman__ | no problem | 07:20 |
| mufasis | does 9.10 ubuntu server come with a gui | 07:47 |
| jmarsden | mufasis: No. | 07:49 |
| 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 .. | 07:50 |
| 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? | 07:51 |
| 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? | 07:52 |
| 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 :) | 07:53 |
| 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 =/ | 07:54 |
| 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? | 07:55 |
| 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. | 07:56 |
| 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 | 07:57 |
| 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). | 07:58 |
| 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 | 07:59 |
| 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 | 08:12 |
| 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 | 08:13 |
| Callum__ | awwwwww | 08:25 |
| mufasis | back sry guys | 08:25 |
| 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... | 08:26 |
| 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 | 08:27 |
| 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 | 08:28 |
| 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 | 08:29 |
| 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 | 08:30 |
| 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? | 08:31 |
| 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 | 08:32 |
| 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 | 08:33 |
| 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 | 08:36 |
| mufasis | no ive installed ubuntu before but i dont know which packages i need and what does what | 08:37 |
| 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 | 08:38 |
| qman__ | go ahead and paste the link | 08:39 |
| qman__ | I wouldn't be surprised if the drivers are included, given the how old the hardware is | 08:40 |
| 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 | 08:42 |
| 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? | 08:43 |
| 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 | 08:44 |
| qman__ | I'd go with that one | 08:45 |
| 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 | 08:46 |
| qman__ | especially when you're dealing with drivers | 08:47 |
| 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 | 08:50 |
| mufasis | what is the best way to partition the drive | 08:51 |
| mufasis | i have 80gb to work with | 08:51 |
| qman__ | in your case, one big partition should be fine | 08:52 |
| qman__ | the 'guided (use entire disk)' option | 08:52 |
| 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 | 08:53 |
| 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? | 08:55 |
| qman__ | Roxyhart0, that's _really_ not a good idea, but to answer your question, you must use smbpasswd -a to create a new one | 08:58 |
| Roxyhart0 | yes | 08:59 |
| mufasis | doesnt the guided partition option make several partitions though? one for swap / /home etc? | 08:59 |
| qman__ | mufasis, no, just a / and swap | 09:00 |
| 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 | 09:01 |
| Roxyhart0 | but i did before | 09:02 |
| 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 | 09:03 |
| qman__ | if you need to do a lot of things as root, use sudo -i | 09:04 |
| Roxyhart0 | i did, i access with my username and still the same error: Failed to add entry for user rosa. | 09:05 |
| qman__ | does smbpasswd also fail without -a? | 09:07 |
| qman__ | (for rosa) | 09:07 |
| qman__ | -a is only needed when a user does not already have an smbpasswd set | 09:09 |
| mufasis | thank you qman ur awesome | 09:09 |
| 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 | 09:10 |
| 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 | 09:15 |
| 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 | 09:16 |
| Roxyhart0 | thanks np | 09:17 |

| 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? | 19:31 |
| guntbert | JohnA: 1) use ssh, 2) should be a bios setting (if you are talking about power failure) | 19:32 |
| 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 | 19:36 |
| guntbert | JohnA: then I'd next assume a harware issue (heat, memory,...) | 19:37 |
| 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 | 19:42 |
| 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 | 19:45 |
| guntbert | JohnA: did you run them through? the tests 1-5 are only for the worst cases | 19:46 |
| 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 | 19:47 |
| guntbert | stas: you cannot - as far as I know | 19:48 |
| 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 | 19:49 |
| 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 | 19:50 |
| 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 | modprobe -r the driver | 19:56 |
| stas | and modprobe it back | 19:56 |
| stas | :) | 19:56 |
| guntbert | stas: grand :) | 19:56 |
| stas | thanks again | 19:56 |
| guntbert | stas: *you* solved your problem :) | 19:56 |
| JohnA | guntbert: does setting kernel.panic in sysctl work in ububtu? | 19:56 |
| stas | :) | 19:56 |
| guntbert | JohnA: no idea - sorry | 19:57 |
| JohnA | guntbert: not to worry, I'll try it and see what happens. thanks, take care | 19:58 |
| guntbert | JohnA: Good luck :-) | 19:58 |
| enherit | how can I create a "nginx" user with the same options as "www-data" user? | 19:58 |
| sherringham | enherit: explain "options"? What are you trying to do? | 20:00 |
| enherit | www-data doesnt' have home dir. | 20:01 |
| enherit | www-data is used to run the apache process. I want to create a user just for running a process | 20:02 |
| guntbert | enherit: www-data *has* a homedir set | 20:03 |
| enherit | hmm. I think what I want is "a system user" | 20:04 |
| enherit | what are "system user" good for? | 20:05 |
| sherringham | See: man adduser (you probably don't need a "system" user i.e. id < 1000) | 20:06 |
| enherit | thanks. | 20:06 |
| 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 | 20:55 |
| ubottu | kvm is the preferred virtualization approach in Ubuntu. For more information see https://help.ubuntu.com/community/KVM | 20:55 |
| MTecknology | lifeless: how hard is it to learn to setup a vm in say an hour or two? | 20:57 |
| lifeless | depends | 20:57 |
| 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 | 20:58 |
| 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 :) | 21:01 |
| 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) | 21:02 |
| MTecknology | yup - I'm there | 21:03 |
| MTecknology | I like the kvm virt-viewer ssh+ | 21:03 |
| MTecknology | qemu+ssh* | 21:04 |
| 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 | 21:06 |
| 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 | 21:07 |
| lifeless | do you have /usr/bin/nmblookup | 21:10 |
| 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? | 21:12 |
| 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 | 21:13 |
| 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? | 21:14 |
| 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 | 21:15 |
| 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 | 21:16 |
| 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 |
| === chrisboom_ is now known as chrisboom | ||
| 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 | 21:17 |
| MTecknology | lifeless: I'm only goingt o use kvm on this - I'm just trying to understand cloud computing | 21:18 |
| 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' | 21:19 |
| 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) | 21:20 |
| lifeless | thats about the size of it | 21:21 |
| 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 | 21:22 |
| 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 | 21:23 |
| 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 | 21:24 |
| 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 | 21:25 |
| 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 | 21:26 |
| 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 | 21:27 |
| 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? | 21:28 |
| 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) | 21:29 |
| MTecknology | lifeless: so two whole separate clsuters, then you setup the app so it runs in both systems simultaneously.... does mysql/apache support that? | 21:32 |
| 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' ;) | 21:33 |
| 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' | 21:34 |
| lifeless | k, gotta run | 21:35 |
| MTecknology | lifeless: I'm all for the reliable | 21:36 |
| 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? | 21:59 |
| 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 | 22:00 |
| guntbert | Zajjko1: if I remember correctly you are dropped to a root console | 22:01 |
| Zajjko1 | Right on. | 22:02 |
| Zajjko1 | Hold on, though. By default in ubuntu server, root has no password and does no allow login | 22:03 |
| Zajjko1 | Come to think of it, that is by default in ubuntu overall | 22:04 |
| guntbert | Zajjko1: should be no problem in recovery mode | 22:06 |
| guntbert | Zajjko1: works as I said: you get a menu, choose net root and get a root console | 22:08 |
| Zajjko1 | guntbert: Ahh ok. So would I access it from the installed OS or via the install-CD? | 22:13 |
| 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. | 22:14 |
| guntbert | Zajjko1: you boot from the HD, and press <shift> until the grub menu appears, there you select recovery mode | 22:15 |
| Zajjko1 | Thank you, guntbert. Will try that | 22:16 |
| guntbert | Zajjko1: be sure to press <shift> early enough | 22:16 |
