krautmattwalston: it could be usefull to explain, for wich operating system you use a MUA. 10:31
krautmattwalston: and there are many reasons, why a ssh connect takes much time.10:31
krautmattwalston: it would be interesting, wich infos you with -v get.10:32
mattwalstonkraut: as far as mail server, all machines are running 7.0410:32
krautah, you meant a MTA, not MUA.10:32
krautthe question is the same, wich religion you should prefer ;)10:33
krautmany people prefer exim, oter ones postfix or sendmail. i am using qmail, but i can't say, that i prefer it.10:33
mattwalstonkraut: actually, i was wandering if anyone made a prepackaged all-in-one type thing, ala Zimbra or Scalix, i just want less bloat but the ease of administration as I have a lot to do around here10:34
krautand what exactly do you mean with all-in-one?10:34
krautmattwalston: then you need someone, who makes this for you.10:34
krautyou can't setup a mail-system within 5 minutes.10:34
mattwalstonkraut: sure you can, just with about 4 gb of ram and a few headaches next week10:35
mattwalstonkraut: zimbra is a pretty easy install, just big time bloated and slow to apply security updates10:35
krautyep, but it's a topic wich you should take more seriously10:35
krautwich services are included in zimbra?10:35
krautsmtp, pop, imap?10:35
mattwalstonkraut: yes10:36
mattwalstonkraut: it is ment more for the server appliance market10:36
krautmattwalston: for what do you need this mail-system exactly?10:36
krautonly for a few accounts?10:36
mattwalstonbtw, the ssh -v shows the delay between these two lines: debug1: SSH2_MSG_SERVICE_ACCEPT received10:36
mattwalstondebug1: Authentications that can continue: publickey,password10:36
krautor do you have severall thousand users on it?10:36
mattwalston25 users10:37
mattwalstonbut they are huge mailboxes10:37
krautthen i would take something like exim and put the accounts into a mysql-database10:37
mattwalstonit is an engeneering firm that saids scans of prints10:37
krautexim is a mostly "easy to use" MUA i think10:38
krautand for such a small system it would be enough10:38
mattwalstonkraut: so definetly use virtual users?  all mail users have an account on the system10:38
mattwalstonkraut: thanks, i will definetly look into it10:38
krauthmmmmmm, good question10:38
krautit would be better, to take virtual users, because you can't figure out, if everybody will have an account local in future10:39
mattwalstonkraut: good point10:39
krautdo you want only serve pop?10:40
mattwalstonkraut: i am doing this one by the seat of my pants, they have win 2k3 on 3 boxes for running autocad and simulation software, 2 application servers using ltsp, and 34 thin clients throughout office10:40
krautor also imap?10:40
mattwalstonkraut: preferably imap only10:40
mattwalstonkraut: i hate pop but it may be the easiest10:40
krautthen exim+mysql and cyrus would be a nice setup i think10:40
krautand you should also take a look on squirrelmail10:41
krautit's a web-frontend for imap-mailboxes.10:41
mattwalstonoh, for webmail?10:41
krautperhaps a nice feature for them10:41
krautyes10:41
mattwalstonyeah10:42
krautit depends on imap. nothing more.10:42
lcddwhat is the benefit of using sql backend here?10:42
krautlcdd: if you have the accounting data into a mysql-database, it's easier for other applications, to share this informations10:42
krautlcdd: you create a user via exim and cyrus for example could use this information to serve imap-access.10:43
lcddisn't ldap better suited and supported for that?10:43
mattwalstonis there a way to move all the heavy lifting for the mail server to another machine but still deliver to local users maildir?  like via nfs mounting of /home?10:43
krautlcdd: i think mysql is easier then ldap, but yes, that's also a soloution.10:44
krautmattwalston: heavy lifting?10:44
krautyou mean the autocad-data?10:44
mattwalstonkraut: I guess it is all relative, lol, i mean for isolation10:44
krautdon't understand you :/10:45
mattwalstonkraut: i.e. machine 1 handles mta, mda and machine 2 handles /home's and ltsp with a nfs mounted /home10:45
krautmattwalston: depends on virtual or local users10:45
krautbut with some tricks it's possible i think10:46
mattwalstonkraut: i am liking local users, but am not completely opposed to virtual users, i just have not messed with them10:46
mattwalstonkraut: ordinarily, i just outsource the email10:46
krautthat's a point that only you are able to evaluate ;)10:47
mattwalstonis nfs still the prefered way to remote mount?10:47
krautfor linux/unix, yes.10:47
krautbut don't use 2.6.20 or 2.6.2110:47
krautnfs-client is broken in this versions10:48
mattwalstongreat, all machines are 2.6.2010:49
mattwalstonis that why i can only mount if i set nolock?10:49
krautno, 2.6.20 will corrupt your data.10:50
krautthere are issues in write() i think.10:50
krautor file-locking, don't know exactly10:50
krauti am actually using 2.6.17 again and i am testing it now.10:51
=== ivoks [n=ivoks@36-1.dsl.iskon.hr] has joined #ubuntu-server
krautperhaps on wednesday i could rollout this kernel.10:51
mattwalstonI know i have not had any problems with 2.6.17, used it awhile on my web servers10:53
kraut2.6.17 has less issues, but forcedeth.c is for example a crappy-version10:53
krautforcedeth.c is interesting for sun M2-series servers.10:54
lcddisolating services is always a good idea, but if you need to set up nfs and shared user accounts because of it, i don't think it's worth the trouble at all10:57
mattwalstonlcdd: that is what I am thinking... i am just nervous about having a machine handleing up to 14 or so ltsp clients running all sorts of stuff and also using it for email mta and mda11:00
krautmattwalston: i would device this services11:00

=== boxrock [n=chatzill@197.147.121.70.cfl.res.rr.com] has joined #ubuntu-server
lcddmattwalston: i would probably take the lazy route and use the same server, but make sure ltsp clients are under reasonable system resource limits11:21
mattwalstonlcdd: I think that is what I am going to do11:23
boxrockcan anyone tell me how to get widescreen resolutions set on a thin-client ?11:25
lcddmattwalston: if you expect the number of systems increase, then there will of course be good reasons to use some kind of central user management, be it ldap or sql or by copying /etc/passwd over the network etc.11:26

NETWizzHello, at work I installed 37 Ubuntu computers on a LAN11:28
poningruNETWizz: yeah so the best thing would for you to set up your own repository11:28
NETWizzI wish to set them up to install packages automatically11:28
NETWizzOkay, that will be easy11:28
NETWizzBut I still don't have time to go to all the computers and sudo apt-get install package... 37 times11:28
poningruthere are crazier things like apt-caching across networks11:29
poningruNETWizz: oh hmm I see what you are saying11:29
NETWizzCan the systems be configured to do an update and upgrade from our own repository?11:29
poningrusounds like what you are looking for is ltsp11:29
NETWizzI want our systems to get a list of packages they are supposed to have installed and install those that are not installed11:29
NETWizzand remove those that are no longer on the list basically11:29
poningruright11:30
NETWizzltsp?11:30
=== NETWizz Googling
poningruyeah dude linux terminal server project11:30
ivoksno11:30
poningruivoks: better solution?11:30
NETWizzNOpe we don't want to termininal server11:30
ivokssetup one machine11:31
ivoksand then get run dpkg --get-selections &> template11:31
NETWizzBasically I am doing a Windows to Linux Migration in one lab at a High School11:31
ivoksand on every computer: dpkg --set-selections < template ; apt-get dselect-upgrade11:31
NETWizzCurrently our network comprises of 30 sites connected via WAN all running Windows XP Professional11:31
NETWizzI got permission to install Ubuntu on 37 machines at a High School11:32
ivoksor build your own .iso11:32
NETWizzor build my own iso?11:32
NETWizzOkay, so I can make a script to get a template every day11:33
ivoksno11:33
ivoksdon't do that11:33
ivoksyou want regular updates, right?11:33
NETWizzSUre11:33
NETWizzBut I also want to be able to deploy applications11:33
poningruNETWizz: take a look at edubuntu11:33
NETWizzRight now with Windows, I can deploy applications to computers no problem11:33
poningruthis sounds like exactly what this is for11:34
ivoksthen yes, --get-selections11:34
NETWizzDoes edubuntu support deploying apps11:34
ivokswhat poningru suggests is diskless clients11:34
ivoksthere's no deploying apps11:34
ivoksall computers use same filesystem11:34
mattwalstonNETWizz: super easy...11:35
ivokswhen you install app on one, it's installed on all11:35
poningruwell you can have it with disks11:35
NETWizzWhat?11:35
NETWizzI install an app on one and it gets installed on all11:35
NETWizzHOw does that happen?11:35
mattwalstonNETWizz: set-up a cron job on all machines to wget a script and run it from a central location11:35
NETWizzThere must be a process11:35
ivoks23:34 < ivoks> all computers use same filesystem11:35
NETWizzright they all use the same file system11:35
ivoksyes, network file system11:36
NETWizzOh you mean I am going to do a network file system11:36
NETWizzand have only one system for all the computers11:36
ivoksright11:36
NETWizzThat won't likely work11:36
NETWizzToo much network traffic11:36
NETWizzI can install squid11:36
poningru... you can have it with disk11:37
NETWizzThat would at least allow each computer to get updates without hammering the network11:37
ivokswhy do you think it is too much network traffic?11:37
ivoksthey don't send/recive whole filesystem, only needed parts11:37
NETWizzBecause if this project works, we will probably setup hundreds of computers11:37
mattwalstonNETWizz: nfs the /var/cache/apt/archives and add a cronjob to run script from server11:37
NETWizzokay11:38
NETWizzI could just rsync the archives11:38
mattwalstonNETWizz: yeah11:38
ivoksthere's always cfengine11:38
NETWizzwhat would the scripts do?11:38
NETWizztell it to install everything in archives?11:38
ivoksit would do what you want and write in it11:38
NETWizzokay thanks11:39
mattwalstonNETWizz: whatever you wanted, it would just run on all computer... i.e. apt-get update; apt-get upgrade;11:39
poningruNETWizz: http://blog.nixternal.com/stuff/doc/handbook/handbook/C/ltsp-scp.html11:39
mattwalstonNETWizz: there is probably a better option out there11:40
ivoksmattwalston: for that, there's unattended-upgrades11:40
mattwalstonivoks: thanks, will look at it, probably much more secure than letting the root user wget a script and run it... time to backup and punt11:40
poningruNETWizz: I really think that you should look into edubuntu11:41
poningruit is designed for this minus the hdd but that doesnt mean you cnat use it11:41
NETWizzI will look into edubuntu11:42
NETWizzthanks11:42
NETWizzRemote logout!11:42
NETWizzThat sound snice11:42
NETWizzDoes edubuntu get installed on dozens of machines?11:43
poningruright11:43
poningruone server and the rest client11:43
NETWizzplessus looks like gpedit11:48
NETWizznot quite as much stuff11:48
mattwalstonNETWizz: edubuntu pushes for thinclient usage11:48
mattwalstonNETWizz: you might consider running x11vnc on the student machines, then you can snoop, take control and shadow to demonstrate something11:49
NETWizzI am not a teacher11:50
mattwalstonNETWizz: you can also password the screen saver and execute from commandline to blank screens11:50

poningruitalc?11:50
mattwalstonNETWizz: no11:51
NETWizzYou have heard of italc then hugh?11:51
mattwalstonNETWizz: i think it is nt only, we used to piss off our computer teacher by bringing in livecds and booting and his software would not blank us11:51
mattwalstonNETWizz: yeah, real big on k12 with xp clients and nt server11:51
NETWizzWhat do you mean?11:52
mattwalstonNETWizz: I spoke too quickly, i think it doea11:52

NETWizzedubutnu11:56
mattwalstonNETWizz: i have yet to use edubuntu, but essentially it has a lot of features for ltsp built in11:57
mattwalstonNETWizz: i am on an ltsp client connecting to an ubuntu system right now in a engeneering office that I am implenting a thin client solution for their email, webbrowsing, inter office stuff with rdp connections via rdesktop to win 2k3 machines for autocad and stuff11:58
mattwalstonNETWizz: for administrative purposes i even run the win2k3 inside of virtual machines on a linux host, much easier to administer and very flexible, maybe your school is able to glean something from this deployment12:00
NETWizzI have a full district to work with12:01
NETWizzCurrently I have moved some Windows Servers to VMWARE12:01
NETWizzIt was a cakewalk to move them to Ubuntu Server12:01
mattwalstonNETWizz: definetly, something to look at is rdesktop's SeamlessRDP mode for your clients12:03
mattwalstonNETWizz: it establishes rdp to a ts server and uses an alternative shell that sends only the application to the linux client12:03
mattwalstonNETWizz: i have quickbooks ent 7 running that way for a client and it appears native12:04

maccam912hello all. I have an ubuntu server set up, and have a few questions to get it running better than it currently is set up for.12:05
maccam912right now when remote people try to connect to my server, they have to use port 2010, and it works, but for some reason when I try to set it up for port 80 (so they don't need the :2010 after the url) I can get to my website, but no remote users can.12:06
NETWizzI know12:06
NETWizzI have been working with that12:06
maccam912is there something in the operating system that I dont know about that stops remote people from getting on port 80?12:06
NETWizz#!/bin/bash12:07
NETWizzrdesktop -rsound -A -s "c:\seamlessrdp\seamlessrdpshell.exe c:\windows\explorer.exe" 10.24.5.25 -u Linux -p ubuntu12:07
NETWizzOnly thing is that it doesn't seem to support Active Directory12:07
maccam912NETWizz are you just an average joe user like me, or are you like a developer that is trying to fix the problem?12:07
NETWizzI really need to have it popup an active directory login12:07
NETWizzI am an average joe12:08
maccam912and you have the same problem with that?12:08
NETWizzHowever, I am a dilettante or you might call me a dabbler 12:08
maccam912same here12:08
mattwalstonNETWizz: i can login using a samba pdc, just set the workgroup option to your domain, as far as prompting for a login, not too sure12:09
maccam912do you think it might be something with my router instead?12:09
NETWizzI doubt it12:09
mattwalstonNETWizz: come to think of it, it should be able to prompt12:09
NETWizzI wonder if I remove the username and password12:09
NETWizzIt might prompt12:09
NETWizzThat is what I need anway12:09
