here u go

btw thanks for ssh and webserver guides those r setup now :)

12:56 AM

No, I'm looking for the question on the site, it's been asked before :)

ohh I'll search as well

2

Q: Server, gui, then uninstalling the gui

I'm planning to turn my old PowerPC G4 into a wordpress website. I'd like to use the server edition of ubuntu 10.04, install a GUI (to set up wordpress) then uninstall the gui. Would I be able to do that?

4

Q: How to completely remove desktop?

I wanted to switch to xfce (I had kde and gnome installed), and I did this : sudo apt-get install xubuntu-desktop sudo apt-get remove kubuntu-desktop sudo apt-get remove ubuntu-desktop sudo apt-get autoremove but to my surprise, I could still pick gnome, kde plasma, etc during the log in. S...

11.10 kubuntu uninstall xubuntu-desktop lubuntu-desktop

this oen?

ohh ok

That one won't work, deleting the meta-package, as we found out later, won't actually remove all the packages under it

ohh

so need to remove all the stuff

and can I use purge instead of remove?

or not advisable?

1:00 AM

Yes, you can

purge just also removes the packages from cache

hmm and it removes config files right?

I'm back... reading bug report...

@wisemonkey as long as they weren't modified from the package

ok

hmm just gave me bunch of errors that packages couldn't be found, I think I'll remove them one by one

1:39 AM

Good Advice for meta-tags:

21

A: A personal appeal to Jeff Atwood: Recent Changes to Gaming

First, I should apologize for not announcing the changes before I made them. You're right about that. But I felt the tagging issues had gone on for 6+ months with no significant action at all, and even worse, a technical programmer code "fix" to the entire Stack Exchange engine was being promoted...

1:50 AM

death by ~~fire~~ Atwood :)

Is thankful for only having to deal with the Unix and Linux / Ubuntu fracture and no other real drama

was that drama?

As close as we've really gotten to a community brawl (which wasn't really that close)

I do not envy Programmers, or other SE sites who are having regular clashes with Moderator v Community, or Community v Management

Do you remember the Math.SE drama?

Which one? heh, the one about how comments shouldn't be submitted when you press enter?

Or Physics.SE who rebelled so hard against their site theme

@MarcoCeppi Yeah, that one.

2:01 AM

Good times, because Shift+Enter was too difficult

:P

heh

@MarcoCeppi I could use your help if you have a minute

I have all day

Stefano Palazzo

11:35 AM

cool :)

I'm trying to write a script to automatically create a user account. how do I go about setting the password?

3

Q: How to set user passwords using passwd without a prompt?

I am writing a script to add a large amount of users to a system. Part of this involves setting default passwords for each user. How can I set users' passwords without it prompting me for the password up front? Unfortunately passwd doesn't seem to take an argument stating the new password to set...

Stefano Palazzo

I'd really like it if the system were to ask for the password when you first log in

It's in bash?

Stefano Palazzo

oh cool, thanks @Amith

it's in python, but parts of it can be bash, no problem

@MarcoCeppi Isnt there any fix for my problem?

Stefano Palazzo

11:36 AM

def new_user():
    username = '-'.join(str(uuid.uuid4()).split("-")[-1:])
    print commands.getoutput("adduser --system %s" % username)
    return username

this is what I have so far (:

@AmithKK What's your problem?

JuJu

Stefano Palazzo

I'm trying to build a sort of "mini ec2", with automatic VM provisioning

11:38 AM

@AmithKK I'm at a loss, never had that problem before

@AmithKK sudo reboot

Stefano Palazzo

@AmithKK if your system is up to date and you still get this error, you just have to reboot

@StefanoPalazzo One of the Ondina libraries does this IIRC

@StefanoPalazzo Doing an apt-get upgrade

dang, network laggggggggg. @MarcoCeppi - the internet in Virginia SUCKS, mkay? Ohio is much better. ;P

11:40 AM

@jrg Sounds like a personal problem :) You need to be closer to DC Metro area. That's where we keep all the internet

@jrg Iphone fixed?

@MarcoCeppi This sucks. lol.

(then again, i'm here for the food, not the internet)

@AmithKK yeah, turned out to be a software problem that just required me to drain the battery.

@jrg :P no magic camera boolean loops?

@AmithKK nope

Not to mention one of the internet corner stones of the internet is like 30 mins away: Ashburn

HAPPY THANKSGIVING, ENJOY SOME UBUNTU WITH YOUR TURKEY

@MarcoCeppi heh, nice

@Oli you're a pop culture icon now. Little brother just saw your avatar and said "OH LOOK ITS OLI!".

Stefano Palazzo

but it kicks me out right away if I try to log in via ssh

@jrg IRC Pl0x

Stefano Palazzo

11:47 AM

I see, it's got /bin/false as its login shell

@StefanoPalazzo The "false" shell? Never heard of it

hangon a moment @AmithKK

(I am living off SSH now. :P)

Stefano Palazzo

@AmithKK it's just a program that quits with exit status 1

email checked, askubuntu contributed to, ssh checked, irc pongs replied to, i'm set for todays internet. hehe. :D

@MarcoCeppi is there an addicted badge for checking askubuntu during the holidays? :P

@jrg Catching turkey thingies?

11:51 AM

ha, yeah - I wish

I hate it when shipping costs more than the item :)

@AmithKK Yes, I'm going to go turkey hunting. :D

Good luck!

Thanks, the Virginia turkeys are pretty ferocious. ;D (@MarcoCeppi will agree)

@jrg I see tv, so get your compound bows and dont forget to switch off your iPhone

12:02 PM

@AmithKK lol. XD

Oh and to all who live in countries celebrating it:

Happy Thanksgiving!

@jrg Love it :)

What are celebrating again?

Stefano Palazzo

12:22 PM

wow, everything works great this morning :)

1:00 PM

@StefanoPalazzo amith.dyndns-ip.com/image.jpeg The lcdscope works!

Stefano Palazzo

it's not loading here

it might be my fault, I'm doing some unusual things with my network (:

its fixed now

Stefano Palazzo

my message doesn't appear though

Neither does mine

@StefanoPalazzo Ah, sorry the pyserver was not on

Stefano Palazzo

1:03 PM

now it works, fantastic

nice work @amith

Ok, goin down

@StefanoPalazzo @MarcoCeppi Can do better cuz he has an always on computer and(hopefully) a good webcam

That problem I had yesterday, I have typed in to a Question if anyone knows... It is really annoying me!

1

Q: How do I get SSH to listen on a new IP without restarting the machine?

I have a few Ubuntu server boxes set up on ESX, and I changed the IP addresses via SSH. The moment I changed it, it dropped me off of SSH (as expected). After a restart it works 100% as expected and I can SSH in on the new IP. However, as much as this works and I know it is a solution, I am try...

server networking ssh

Stefano Palazzo

@WilliamHilsum I just had something weird happen

when I typed this command, it looked like the SSHd restarted itself

something along the lines of "ifdown eth0 && dhclient -r && dhclient && ifup eth0"

Ubuntu server

Stefano Palazzo

the command is pretty useless I think, but you could try bringing down the interfaces

1:17 PM

@StefanoPalazzo I'm not smart enough really to understand that just yet... does && chain commands then?

... and, what I really don't understand is why I can SSH in from the other computer and not from my remote one

Stefano Palazzo

@WilliamHilsum yes, && means "run the second command if the first command succeeds"

you can chain commands like this: "echo 1; echo 2; echo 3"

but && will stop everything if one command fails (return something other than 0)

@StefanoPalazzo Even 42 ?

Stefano Palazzo

yes

O.o

Stefano Palazzo

~:$ python -c "exit(0)" && echo hello
hello
~:$ python -c "exit(42)" && echo hello
~:$

you can find out the return status of the last command by typing "echo $?"

1:21 PM

ALL of you get accounts on my server, no restrictions :D

but no uptime :P

Segmentation fault
On Vbox

Stefano Palazzo

if you're installing 11.10, I think you have to enable PAE before you install it.

and keep it enabled of course

later :)

I really wish i can get juju

Stefano Palazzo

go to the machine → settings → system → enable PAE/NX

on my desktop

Stefano Palazzo

my machines have been booting for an hour now

1:34 PM

WTF

How did you manage it

(the master host thingies)

AND HOW MUCH RAM?!!

Stefano Palazzo

VBoxManage clonevm "Ubuntu 11.10 Master" --register --name "Ubuntu 11.10 Node 7" &

like this ↑

nice

Stefano Palazzo

each of them has 128 megabytes, and a 40% cpu cap

@StefanoPalazzo cool!

BBL

Stefano Palazzo

1:36 PM

VirtualBox has really come a long way in the past year, but they didn't make any noise about it

things like bridged networking, USB2, cloning, now just work really well

such a shame it's been taken over by oracle

1:59 PM

i'm trying to use gparted to format a CF with UFS, however the option is disabled.

Stefano Palazzo

2:35 PM

@rlemon try installing the "ufsutils" package

it provides "mkfs.ufs"

maybe gparted will pick it up

~:$ apt-cache show gparted | grep Suggests
Suggests: xfsprogs, reiserfsprogs, reiser4progs, jfsutils, ntfsprogs, dosfstools, yelp, kpartx, dmraid, dmsetup, gpart

if gparted doesn't pick it up, you can always run mkfs.ufs manually

@MarcoCeppi why was that deleted?

@Alaukik There's already a gimp one.

@MarcoCeppi so which stays is decided by votes?

I chose the one with the lower of the votes to remove.

We shouldn't have multiple ads for the same thing

@MarcoCeppi ok thanks

ok might be a stupid question.. when dd if=img of=/dev/sdd1 bs=64k what should my block size be (some say 64k some say 1m) and what should my flashdrive be formatted as (ext2? fat32?) should this be on a msdos partition table?

i'm trying to install freebsd from a flashdrive. using gparted to format the drive and dd to copy the image.

I dont remember

@AmithKK helpful response ... =P

-5

A: Is running Ubuntu One on Debian 'possible'?

It's not open-source afaik. Porting it might be an issue... I'm not sure whether this harms the license?

Please kill that answer for me. Thanks.

networking question for you all (pretty basic. I'm just no specialist)

wtf is my host and domain names??

domain should be what i've named it correct?? (like myNetworkDomainName)

Wikipedia is your best friend.

4:55 PM

so if my router is @ 192.168.2.1 is my host 192.168.2.1 ??

yes

Linux didn't make me deal with this shit.. and windows holds you hand through the entire process.
