I was wondering, if the server .iso has the packages required by default for a LAMP installation. (I am installing the server at on my home network which does not have an internet connction at the moment) [04:09] HI, I created a tcp server, running it on ubuntu-server each time i run it, only 400 tcp socket clients can connect to it... [04:09] how do i increase this limit [04:09] to unlimited [05:19] How do I determine which hardisk in my machine is ata2? [05:20] ata2? [05:20] I keep getting these ata2.00 error in the kernel [05:24] I don't think that means ata port 2, but not sure [05:24] I think that means something more like, invalid ata 2.0 command [05:24] as in ata spec version 2.0 [05:25] but need more error message to go with that [05:25] been awhile since I had drive/interface errors [05:26] heh [05:27] Anyone here have any experience with ocfs2? === squishy is now known as SquishyNotHere === SquishyNotHere is now known as squishy [06:32] Hello, I have a question about cloud, if I setup a cloud using 3 machines, is it possible to make a single process to use the processing (& memory) power of all those machines ? [06:45] the reason I ask, is our work environment we use simulators & synthesis tools that (according to the design being worked on) might demand processing power (and/or memory) that is not available in just one single machine. [06:48] AnAnt, no [06:48] I see, so what's the use of cloud ? [06:48] UEC works like standard virtualization, its main advantage is the automated balancing of the load [06:50] if, for example, you had ten servers and needed 50 VMs, instead of having to predict where your load would be, UEC would automatically handle it [06:50] I see [06:51] the only system that ever existed (to my knowledge) that operates like you describe is openmosix [06:51] there is nothing that is currently developed to do it [06:51] the closest modern setup is a clustering system, but that requires threading your application [06:52] some colleage attended some conference about clouds, and there they told him that: cloud = virtualization + clustering [06:53] basically, yes [06:53] but that's all theory [06:53] in practice it's just a really smart virtual machine hosting system [06:54] a great technology to be sure, but not the magical be-all end-all of IT marketers make it out to be [06:55] qman__: do you know if Azure (windows based) can't do clustering the way I described ? [06:56] "The openMosix Project has officially closed as of March 1, 2008." :( [06:57] it can't [06:57] the way those services work, amazon EC2 and such, is just like UEC, but on a very large scale [06:57] they have server farms which run VMs for you [06:58] but any one VM never utilizes more than one bare metal server at a time [06:58] it's just a very efficient and abstract way of running lots of virtual machines [06:59] if you need more power than a single hardware core can give, you need to thread your application [06:59] if you do that, you can cluster and take advantage of as many as you want [07:00] qman__: even OpenMosix needed the application to be threaded ? [07:01] that, I'm not sure of [07:01] ok [07:01] the only theoretical way to spread one thread across lots of hardware is to dynamically thread it on the fly [07:02] qman__: btw, if an application already supports running on several processors, then it is threaded , right ? [07:02] yes [07:02] and if you set up a cluster, it can spread those threads across hardware [07:02] qman__: thanks a lot, you were so helpful [07:02] no problem [07:46] New bug: #692131 in squid (main) "package squid 2.7.STABLE9-2.1ubuntu1 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 1" [Undecided,New] https://launchpad.net/bugs/692131 [08:00] Datz, i ment the one u sent [08:33] hi all [08:33] i have a problem with my FTP server ... i can access it and list folders content from local without problem but when i try using my public IP, it connects very well but does not allow me to list files/folders ..

[09:21] plzzz need help with FTP server [09:21] (pure ftpd) [09:31] it's because FTP is ancient, a total mess, and a security nightmare [09:32] you shouldn't use it unless you absolutely have to [09:52] and, if you really need to, use vsftpd :) [10:19] !Bazaar [10:47] ivoks++ [11:27] New bug: #692171 in nut (main) "using BUS= in udev rules causes system boot error/warning" [Undecided,New] https://launchpad.net/bugs/692171 [11:55] Hi , I have just installed webmin and I am being prompted for a passwprd! [11:58] !webmin | Syria [11:58] Syria: webmin is no longer supported in Debian and Ubuntu. It is not compatible with the way that Ubuntu packages handle configuration files, and is likely to cause unexpected issues with your system. [11:58] ahhhh [11:58] qman__ thnx [11:58] qman__ is there any alternative please? [11:59] !ebox [11:59] ebox is a web-based GUI interface for administering a server. It is designed to work with Ubuntu/Debian style configuration management. See https://help.ubuntu.com/community/eBox [11:59] qman__ thnx. [12:02] qman__ Can you tell me how to remove webmin now please? [12:03] apt-get remove --purge webmin [12:03] apt-get install ubuntu-operation-knowledge [12:03] sudo apt-get remove webmin [12:03] Thnx [12:03] :þ [12:06] sudo apt-get install ebox I am installing ebox using this command, is this the latest version? [12:08] assuming your repositories are correct and up to date, it will install the latest supported version for the version of ubuntu you have installed [12:09] qman__ I am installing it on my 10.10 Maverick. [12:19] Syria: keep in mind that for most setups, learning the basics needed to do the administration from the commandline is usually not too hard, and learning it means you'll understand things better than talking to a stupid gui trying to do your job [12:20] Syria: what sort of server is it you're installing? [12:20] RoyK i am testing it now on my laptop, and then i will install it on my vps which is running on ubuntu 10.4 lucid [12:21] what sort of server? web? php? database? some wierd application? [12:21] if it's just web, I'd say forget about webmin/ebox, and learn the config files [12:21] it _really_ is't that hard [12:24] I agree completely [12:25] it's also mostly set and forget [12:25] configure automatic updates and you won't have to touch it but once a year or so [12:25] RoyK i want to install wordpress i have about 3 sites that I will host on that vps. [12:25] Syria: then do it manually. you'll learn a wee bit about it as well [12:26] RoyK yeah I did this on the old server but I want to test something like webmin or zentyal. [12:26] why? [12:27] it's just another thing that can fail [12:27] I want to know more about it. [12:27] and corrupt your config [12:27] qman__: how about kernel upgrades? [12:27] Syria: I see :) [12:27] Nafallo, scheduled reboots or ksplice [12:27] Nafallo: most of them aren't really needed :þ [12:27] ksplice doesn't do it automatically though [12:28] it does if you add it to cron [12:28] Syria: still, I'd recommend focusing on manual config [12:28] heh. point well made [12:28] it's how I have run my router for the last year and a half [12:28] zero downtime [12:28] RoyK That's why I want to test it on my laptop first. [12:29] RoyK I am not sure about installing it on the vps yet. [12:29] Syria: which is good - always test in a VM before trying to put it into prod... [12:29] Syria, installing such a system is adding a lot more points of failure and increasing security risks significantly [12:29] Syria: keep in mind that databases don't usually run well on VMs, so you might want to ask the ISP if they have a dedicated mysql db for wordpress to use [12:29] they're nice tools for the ignorant masses but for this type of thing it's much better to do it manually [12:30] I have installed apache2 php5 and mysql on the vps server. [12:30] qman__: and the bad thing about those tools, is that the masses of ignorant people is shrinking as manual configuration gets simpler :þ [12:30] and if zentyal or anything else failed i can configure things manually right? [12:31] the main problem is that these tools, if not carefully designed, leave a huge mess in their wake [12:31] Syria: possibly [12:31] this is why webmin is not supported [12:31] Syria: but why bother? [12:31] Syria: doing it from the commandline is _simple_ [12:32] yeah i have been learning how to use the terminal recently. [12:32] server administration is, in my opinion, something that should not be trusted to an abstracted tool [12:32] Syria: still, check if the ISP has a dedicated mysql server. VMs (including VPSes) aren't well suited for running DBMSes [12:33] RoyK Yes I have installed a mysql server and things are just fine. [12:33] even though mysql is pretty close to flat files in the DBMS perspecitive... [12:33] RoyK http://xtrahost.co.uk/ [12:34] Syria: not saying it won't work - the I/O speed from a VM is usually far lower than on a dedicated box, so you really don't want to run something like a database on it [12:34] RoyK How can i check? what should I ask about exactly. [12:34] RoyK aha [12:35] RoyK i will ask them if the vm machine can run data bases without causing any problems right? [12:35] just justask them if they have a mysql database you can use [12:35] if your database is very low traffic it shouldn't pose a problem, but for anything above really light loads, you'll want something that performs better [12:36] last I checked, wordpress only supports mysql, so a postgresql db won't work too well [12:36] Yeah it is a small wordpress data base, I am using it as cms. [12:36] I hope that it will not pose any problems but I will ask them anyway. [12:37] Syria: if you expect some traffic on it, move the database OUT of the VM [12:38] RoyK Thnx for the advice. [12:38] Technical support is avialable monday to friday! [12:39] 9 - 6 pm! [12:39] ouch [12:42] heh. at least you should get good connectivity to Ubuntu archives ;-) [13:00] Can I move copy folders from my computer to the remoter compuer using ssh terminal? [13:01] yes [13:01] see sftp and scp [13:01] qman__ yeah sure sftp. [13:01] qman__ Connect to server from the places menu right? [13:02] yes [13:02] qman__ Can I do this using the terminal? i know it is useless just want to know if yes. [13:06] yes, the commands "sftp" and "scp" can use ssh to transfer files [13:06] sftp operates like ftp, while scp works like cp [13:06] thnx again :) [13:06] no problem [13:17] Anyone here know how the mumble-server sends and recieves VoiP traffic? Does it all get routed through the server or does traffic only travel in a p2p fashion? [14:13] olliel: I think it uses RTP like everything else [14:13] olliel: and I somehow guess the traffic is routed through the server to ease NATing [14:14] sending RTP streams directly involves serious NAT hacking known to SIP and H.323 [16:11] Can I run .NET apps on Ubuntu hardy ? [16:36] hey guys has anyone else experienced issues with formatting a single 2tb partition? [16:37] * RoyK hasn't [16:37] why am i O_o [16:38] seems like anything larger then 1tb will format [16:38] O_o [16:38] what sort of problems? [16:38] what fs type? [16:38] formatting shows 33% then no activity light [16:38] ext4 the default [16:39] ext4 supports far more than 2TB [16:39] ya but im having issues [16:39] during install? [16:39] ya [16:40] what I'd do first is to overwrite whatever partition table the drive has [16:40] mind this will remove _all_data_ from the drive [16:40] already done and chose 1tb instead of 2 [16:40] i set it up with lvm so i can increase the size to 2tb [16:40] formatting with 1tb formatted just fine [16:40] RoyK: outa curiosity what make is ur drive [16:41] bah :( ran into a corrupt den :( [16:41] let me go back again [16:41] also, with such a disk size, I'd use a smaller (20-50GB) root and then use another filesystem for the data [16:41] trying to setup ubuntu cloud feature [16:41] by resetting the partition table, I mean dd if=/dev/zero of=/dev/yourdevice [16:42] oh [16:42] just in case there is a bad-but-somehow-working partition table (layout) on the drive [16:42] ok [16:42] how can i do that off the installation cd? [16:42] just press enter through the first steps, then alt+right, and you have a console [16:43] right what? [16:43] right arrow key [16:43] ok [16:43] RoyK: do i do it from busybox [16:44] yes [16:44] but try to start with a small root fs [16:44] how can i check the device [16:44] no reason to make a root fs on the whole disk [16:44] just let the installer go so far as to find the drives, then you'll find them in 'cat /proc/partitions' [16:46] command is running [16:46] just interrupt it [16:46] it doesn't take very many milliseconds to overwrite what's needed [16:47] ok [16:47] then reboot onto the install cd, make a smallish root partition, install there, and make the data partition later [16:47] smallish is something between 5 and 50GB [16:47] depending on how much you plan to put there [16:47] 5 should suffice for most needs, 50 is plenty [16:48] what if i want to use lvm [16:50] you can set that up later [16:50] ok [16:50] just separate the data from the OS [16:50] that's always a good idea [16:50] let me erase the partitionsok [16:50] ya [16:51] you just erased all the partitions on that drive with dd [16:51] Someone familiar with "hardinfo"? I noticed that it can run as a command line program aswell, but the silly thing is that installation of "hardinfo" requires gnome (http://pastie.org/1390103) But on my server I don't want to install grafical interface [16:51] eagles0513875: just create a simple partition for root, one for swap (size of memory or so) and leave the rest for later [16:51] ok [16:52] RoyK: should i allocate 24gb for swap [16:52] i have 8gb in this machine [16:52] you probably won't need it [16:52] just allocate 8 gigs [16:52] ok [16:52] you can add more later if you need more [16:53] how exactly does cloud computing features work? [16:53] adac: looks like a gui for lshw to me [16:53] RoyK, you can also start it on command line only [16:53] ahh [16:53] lshw [16:53] is a program [16:53] :) [16:54] eagles0513875: it's just virtualization gone large [16:54] RoyK, I first thougt it was some nasty shorthand form for some word ;) [16:54] :) [16:54] RoyK: i have a server is the vt-x extension necessary [16:55] eagles0513875: last I checked, kvm needs that, yes [16:56] eagles0513875: http://www.linuxquestions.org/questions/linux-kernel-70/kvm-without-intel-vt-or-amd-v-530789/ [16:56] :-/ i know i tried kvm on this machine but what services can i setup using cloud computing on this server which doesnt have it [16:56] seems you can run it without virtualisation hardware, but it'll be slow [16:56] RoyK: you said 8gb swap 50gb / then what bout the rest [16:56] just leave it for now [16:57] eagles0513875: if you don't know the difference between cloud computing and virtualisation, you don't need cloud computing [16:57] eagles0513875: then just setup a box, add VMs to it, relax, it'll work [16:57] RoyK: i know what virtualization is just not understanding what cloud computing is [16:57] i would like to eventually use cloud computing for my business [16:57] eagles0513875: if you need 1,000 VMs, you might need a private cloud [16:58] if you need 10 or 50 VMs, you probably just want a machine with kvm [16:58] atm dont need many [16:58] there you go, then no need for cloud [16:58] clouds aren't very simple to setup [16:58] and you can migrate to a cloud later [16:59] RoyK: ok resstarted installer and did the partitioning [17:00] i have 300mb partition for biosgrub 8gb swap 50gb root hat do i do with the 1.9 that i have left [17:00] wtf [17:00] RoyK: machine randomly restarted itself [17:00] oops [17:00] run memtest86 [17:01] done already [17:01] ram is fine [17:01] hm [17:01] after getting em back from corsair [17:01] shouldn't reboot on its own, though [17:01] im thinking its a psu issue [17:01] check the logs first [17:02] i have nothign to boot onto os wise [17:02] erm - it rebooted during install? [17:02] while i was setting up the partitions prior to starting the format [17:03] eagles0513875: anyway - start over - partition as you did and try again. never mind the extra non-partitioned space - we'll deal with that later [17:04] ok [17:04] New bug: #589647 in net-snmp (main) "snmpd starts (and dies) before network is up" [Undecided,Confirmed] https://launchpad.net/bugs/589647 [17:04] might have to do this later [17:14] RoyK: is it easy to install the necessary stuff later for cloud computing? [18:15] http://www.pastebin.ca/2023686 [18:15] What would cause errors like that [18:27] eagles0513875: cloud computing is for a cluster of computers running VMs. when you need it, you will have time to set it up [18:27] eagles0513875: and no, it's not particularly easy to setup either way [19:16] X2 zone, why do I need to create a different zone *ip subnet* for x2 port that connects to the ssl vpn x0 port, are vpn user on a different ip subnet from lan user? is that the norm " [19:40] seriously i dont know which line to choose [19:40] phenom 2 black or intel i series [19:40] anyone? [19:47] there are intel people, and amd people :P [19:47] yea i know [19:48] but id love to hear personal experience [19:48] * Datz shrugs, I am an intel person [19:48] hehe [19:48] hey all im going crazy here trying to change the ssh port. Firt of all im diabling ufw then im editing /etc/ssh/ssh_config to aay and empty port then reloading the ssh service but ssh -p localhost returns connection refused [19:48] any ideas?

[19:50] yeah [19:50] same subnetwork [19:51] humm, and you restarted sshd? [19:51] oh I see you said that [19:51] i think that this is right /etc/init.d/ssh reload [19:51] right? [19:52] I'd think that would work. I guess you could try restart as well. [19:53] alright let me give that a try [19:53] * Datz is no expert [19:54] hey wha thappens when a road wwarrior has the same subnet as the remote vpn tunnel [19:54] what if he is setup on a different zone but both remote and local network interface are on the same subnet [19:55] wizardslovak: you could go for the underdog :p http://www.networkworld.com/news/2010/060710-tech-argument-amd-intel.html [19:58] How come Ubuntu loops on the recovery menu after I asked it to shutdown? [19:59] 'sudo shutdown now' - shut down services - recovery boot menu (???) - restarts all services. [20:00] just trying to shutdown? I usually "sudo shutdown -P now" [20:01] thanks much, that worked [20:01] np [20:02] vadi2: man shutdown [20:02] What would cause errors like: http://www.pastebin.ca/2023686, I'm getting them for ata2.00 and ata8.00 === Acwb is now known as Acwb_ === Acwb_ is now known as Acwb [20:19] User792: no luck?

For some reason when i go to domain.com/phpmyadmin i just download a file called download. Anythoughts? [20:43] wouldn't it be easier to check netstat -ltun and determine the number of lines, and warn if the number is higher than the threshold? [20:43] pmatulis, maxagaz ^-- [20:45] Nafallo, good idea [20:46] might want to use -p as well and grep out some applications and stuff bound to 127.0.0.1 [20:47] if someone has time can you go to lb.1pristine.com/phpmyadmin and let me know if you have any ideas why it is not working? [20:50] clayd: how did you install phpmyadmin? [20:50] with the aptitude [20:51] yes "the" aptitude :) sorry about that [20:51] sudo aptitude install phpmyadmin [20:52] i think it is a configuration issue between using mod_fcgid and the default phpmyadmin install [20:52] ok, just checking [20:53] i found something talking about adding a .htaccess file that handled RewriteEngine and rrewriterule [20:53] do you need to restart apache when you add a .htaccess file? [20:55] not from my experience [20:55] that is what i am thinking [20:55] clayd: you might try #httpd if you have not already [20:56] i am hoping not to but that is what i might end up doing. [21:25] hey, I want to update a network card driver. But im worried the eth connection will drop and then I wont be able to reconnect to my server to put it back up? How likely is that? [21:29] DormantOden, hard to say. If access to the hardware is impossible, I'd leave it. [21:29] yea, I guess I'll have to [21:30] cheers milligan :) [21:30] Didn't do much to help, I'm afraid .. but afaic, if it ain't broken, don't fix it ;9 [21:31] its a super slow samba problem :P [21:32] broken, but can't fix it until I go home :/ [21:32] You know for a fact the prob is caused by nic drivers? :( [21:33] no, but there isn't a fix that has worked and the only one left (bar this) is: "buy a new nic card" which I dont really think counts xD [21:38] any thoughts milligan? I'm going to be bored as hell without my samba =D [21:38] What's the problem, exactly ? You're experiencing poor transfer speeds on samba ? [21:39] And you're sure it's not some sort of switching problem in regards to speed negotiation etc ? [21:42] not sure what it is really, just trying whatever I can. [21:42] What are the symptoms? I doubt I'll be of any help, but I can give it a shot :) [21:42] well, over a gigabit lan it will transfer at anywhere from 1 to 10 meg/s [21:43] but now im externally connecting I'm getting nothing higher than 100kb/s on a 17 meg line. [21:43] just dosen't seem right... :/ [21:44] the servers connection has an upload speed of 2 megs, so I figured I should be getting at least 500kb/s [21:45] it doesn't transfer stable on a lan connection .. ? [21:46] it will usually stay stable. but it likes to stick at a certain speed for random amounts of time [21:46] if your upload on the server is 2mbit .. you won't be getting more than approx 250kb/sec download over the internet... [21:46] hmm [21:46] one day it will be going at 1 meg, a few days later its going at 6? [21:47] reseting the routers and computers won't solve it, never tried reseting the server though [21:47] well, I meant a speed tests upload rate will max at about 2 meg [21:48] 2MB/sec ? [21:48] yea [21:49] we sacrifice download speed for upload speed =) [21:49] to debug it, I'd do testing locally first. Check and double check that you get stable transfer speeds across the network using a proper protocol. iperf or simple ftp tests would suffice I rekon. [21:50] ok [21:50] if your network at home is stable, you're ready to check the next step .. if it's not, start looking at the equipment you have at home [21:50] If you have a gigabit network at home .. you probably have a cisco or a hp layer 2 switch ? [21:50] why? [21:51] not sure, switch is under some wood and all I can see is the word "Gigabit switch" =P [21:51] there are other brands that support gigabit :) [21:51] cheaper [21:51] like dlink :) [21:51] eeeew [21:51] yeah [21:51] ivoks, just figuring that if one goes to the lengths of building fully supported gigabit, one would do it with proper equipment ;) [21:52] milligan: not a valid assumption, at all. [21:52] Whatever. Let's see you debug it :) [21:52] people don't do that for companies [21:52] I actually bought it by accident. They were susposed to give me a normal 100mb/s switch :) [21:52] gigabit is very very common these days [21:52] i'd like to see a person that has cisco at home :) [21:52] DormantOden, do you have the single switch, or several ? [21:52] single [21:52] ivoks: o/ [21:52] cashing out that much money for nothing... [21:53] ivoks: but I'm a bit special I guess ;-) [21:54] also, my equipment is all sorts of brands and stuff :-P [21:55] milligan: I mean, even dropbox over the network is pretty instant. But your right I should properly test it using ftp. [21:55] Nafallo: well, you are an exception :) [21:55] :) [21:55] 1-10 MB/s over gigabit sounds like some serious problems. [21:55] only with samba [21:56] samba between linux machines? [21:56] linux and windows and macs [21:56] well.. the macs dont really count [21:56]
