[03:47] <darthanubis> Is there a way I can install ltsp WITHOUT Unity as the default kit? Can I choose which desktop enviroment?
[04:08] <jeffrubic> If I've originally installed a package via a ppa, then it's later added to the official ubuntu distro, is there anything I need to do to avoid conflicts between the two?
[04:39] <hotswaphdd> hi
[04:40] <hotswaphdd> anyone around?
[04:45] <tgm4883> hotswaphdd, it's better to just ask your question and wait
[08:01] <sliddjur> Hello I am completely new to ubuntu server. what text editors are there? i saw the command vi and nano?
[08:03] <sliddjur> ":q!CR	quit, discarding changes" how do i type :q!CR??
[08:03] <sliddjur> in vi
[08:18] <seekwill> sliddjur: Press ESC first, then :q!
[08:18] <seekwill> CR means "enter"
[12:37] <koopa58> Somewhere on my vps something keeps on sending e-mails to postmaster@vps1.domain.com. How can I find out what script is doing this? I'm using sSMTP with Sendgrid.com.
[12:37] <koopa58> I've set MAILTO="" inside crontab, but this was of no help.
[12:37] <koopa58> And sSMTP does not use /etc/aliases or /root/.forward
[12:38] <koopa58> Any suggestions very welcome, as my reputation on Sendgrid is dropping and the e-mails send to that address keep on bouncing.. :(
[13:14] <koolhead17> hello all
[13:21] <koopa58> Hello koolhead17
[13:23] <koolhead17> hi koolhead17
[13:23] <koolhead17> hi koopa58 :P
[13:24] <koopa58> :)
[13:40] <maxb> koopa58: pastebin an example message with full headers?
[14:00] <koopa58> maxb: I'm not sure what message is being sent.. I only see in sendgrid that it is sent to an address that does not work and thus bounces..
[14:01] <qman__> this is why it's better to use a real MTA
[14:01] <qman__> proper logging and diagnostics, ability to filter things out
[14:01] <koopa58> I do know this: http://serverfault.com/questions/421336/prevent-postmasterdomain-com-bounces-with-ssmtp-and-sendgrid
[14:03] <koopa58> Hope it is of any help, or anyone that might know where I can find more information..
[14:04] <qman__> you'll probably have better luck elsewhere, as postfix and exim are the ubuntu-supported MTAs
[14:05] <koopa58> qman__: Ah, but I need courier or dovecot with those as well or not?
[14:05] <qman__> no
[14:06] <qman__> courier and dovecot provide pop and imap
[14:06] <qman__> if you don't need those, don't install them
[14:07] <koopa58> Hmm.. can I use postfix like sSMTP so that all mail is handled via Sendgrid, and does Postfix then log more information?
[14:08] <qman__> I don't know anything about sendgrid, but postfix can be configured to use a smarthost if that's how you're doing it
[14:08] <qman__> and it can be configured with any number of additional filters, like anti-spam and antivirus
[14:08] <qman__> it's also one of the most widely used MTAs, so online documentation is very good
[14:10] <koopa58> I need something that is easy to setup :) and I only need to send e-mails. Also I've learned that I need to be able to retrieve local mails the system might send..
[14:11] <koopa58> Disabling courier would be dangerous?
[14:11] <qman__> it doesn't get much easier than postfix
[14:11] <qman__> apt-get install postfix, answer a few questions in debconf
[14:11] <qman__> courier is not needed at all
[14:12] <qman__> system mail is delivered locally, and can be retrieved using local mail clients
[14:12] <koopa58> Hmm.. someone said to me: "You need local mail delivery - just disabling Courier compromises the functionality / security your system - you need to replace it with a local MDA such as deliver / procmail"
[14:12] <koopa58> Do you know what they mean?
[14:13] <qman__> partly correct in that you still need local mail delivery
[14:14] <qman__> but removing software doesn't compromise security
[14:15] <koopa58> Aha okay, I also found out about the `mail` program, I could use that to retrieve local mail am I right? I have never seen anything come up in there so :)
[14:15] <qman__> yes
[14:15] <qman__> ssmtp probably doesn't do local mail delivery, so if you continued to do that you'd need procmail or similar
[14:15] <koopa58> Ah thanks for clearing that up :) so `mail` could handle the local mail
[14:15] <qman__> but postfix can do it all
[14:15] <koopa58> Oh okay
[14:16] <qman__> you can optionally use procmail with postfix, too
[14:16] <koopa58> And procmail is like `mail` a client to retrieve mail?
[14:17] <qman__> no
[14:17] <qman__> it's a delivery agent, for local mail
[14:17] <qman__> you still need a mail client like 'mail' to read it
[14:17] <koopa58> Okay, would I need procmail or is it only for filtering and such?
[14:18] <koopa58> Considering what I have setup in /etc/aliases and ~/.forward
[14:20] <qman__> not strictly necessary, just optional
[14:23] <koopa58> Okay, thanks :) I'll try out postfix.. hope I can catch the program that is sending to that address.. I assume postfix also would log in /var/log/mail.* ?
[14:25] <qman__> yes
[14:25] <qman__> it doesn't log the full content of the messages by default but you can turn it on
[14:25] <qman__> but it does log when and where it's sending them out of the box
[14:26] <koopa58> Ah okay, great! Thanks, I'll try it out
[14:52] <koopa58> Getting some more info with Postfix now.. but it still seems to use the address root@vps that does not exist.. http://pastebin.com/xiN1rX43 any ideas?
[14:58] <koopa58> It seems like there are 2 emails being sent
[18:03] <mwcampbell> Why are there two LXC templates for Ubuntu, "ubuntu" and "ubuntu-cloud"? What distinguishes them?
[18:06] <stgraber> ubuntu builds the template from scratch using debootstrap, ubuntu-cloud downloads a pre-built cloud image from the internet
[18:07] <mwcampbell> When should I prefer one LXC template over the other? For example, is ubuntu-cloud primarily intended for use with OpenStack?
[18:10] <stgraber> ubuntu-cloud is going to offer you a behaviour identical to the ubuntu cloud AMI that you'd run in EC2 or other cloud providers
[18:10] <stgraber> however it requires downloading the pre-built image, so if you already have a local mirror, it won't be able to use it
[18:11] <stgraber> also, the image might not be fully up to date, so you may need to apply updates afterwards
[18:11] <stgraber> the lxc-ubuntu template instead builds it locally for you, so if you have a mirror, it'll use it as the package source and it'll be perfectly up to date as it'll be building the template the first time you want to use it
[18:12] <mwcampbell> stgraber: Thanks for the explanation.
[18:12] <mwcampbell> I also see that lxc-ubuntu lets me share my user account and home directory between the host and container(s). That looks quite handy.
[18:13] <stgraber> yeah, lxc-ubuntu has a few more options than the lxc-ubuntu-cloud template
[18:14] <mwcampbell> So I'll use lxc-ubuntu-cloud if I want to test something that I intend to deploy to EC2 using the Ubuntu AMI
[18:14] <stgraber> yep, that'd be the best template to use for that case indeed
