dd if=/dev/orig of=/dev/new bs=1M

grow partition to new size with parted. (Or you can use ext2resize.)

So I set up an alias so that when I enter the command "tunnel" my eee will connect to a server at home on a specified port via SSH. (Thus I can use foxy proxy to tunnel all my browsing through it)

Anyways, I restarted the Eee after installing some updates to Ubuntu, and when I type "tunnel" nothing happens, it appears the alias is gone. Is this normal? Do I need to write in a file somewhere to make an alias permanent?

Yeah, put it in .bash_rc to make it set the alias everytime you open a shell.

Oh then you already have your restored drive and you are growing it on another drive. Even easier. Like the other guy said, dd from small drive to larger. Then grow the filesystem. You have your data on the smaller drive if anything goes wrong so no worries there. http://www.gnu.org/software/parted/manual/html_mono/parted.html#SEC30
Or if you use gparted you can do it with a GUI.

Its easier to do dd disk to disk because that will preserve the bootloader and all that. If you went and formatted the bigger drive, then did rsync from the smaller one to the new filesystem you would have to reinstall grub on the bigger drive.

I am trying to get a scanner working in xubuntu 9.04. I have installed sane/xsane. Everything works fine as root, but if I run xsane as a regular user I am told "access to the resource has been denied", or something to that effect. I have added my user to the saned group. There is no "scanner" group, as far as I can see.

What should I do here? This is a usb Epson V500. Thank you.

Thanks for the help all, system is back up and running and I've saved us having to pay $6500 to our supplier for an out of warranty repair by grabbing a random HDD that was sitting on a shelf collecting dust.

In the end I just did the dd, didn't bother with the partition stuff, it'll just go on with it's life thinking it's a 80gig drive and that should be fine.

I'm currently on a Fedora-machine, and could really benefit from some kind of SSH-manager of some sort. I basically just want a better overview over my outgoing connections, as I usually spawn a shitload of them through an entire day.

It doesn't matter if it's a terminal or GUI-based deal, as long as it's easily readable, and somehow groups or organizes my ssh-terminal windows, sessions, etc.

Any suggestions?

I use 'screen' pretty heavily for that, most if not all distros have it in their package manager. Its a terminal multiplexer, which means you can create several different windows that spawn terminal sessions within a 'screen' session. From there you can run ssh on each of those windows and it will keep that connection for as long as screen is running/that window exists. Which, since you can detach screen and let it run as a background process, can be pretty indefinite. You can name your windows and bring up a listing of all the given windows to jump between.

I run it on a network jump box at my job, and at any given time can just reattach one of my screens and have 30+ ssh connections open for easy switching between servers.

On Ubuntu, users need to be in the scanner group. In GNOME's System > Administration > Users and Groups there's a checkbox for it, I'm not sure if XFCE has a GUI tool.

fourwood: Sep 9, 2001; Damn I'll bring them to their knees.

Does anybody know how to modify the amount that the volume adjustment buttons and the brightness adjustment buttons change the system volume and screen brightness? For brightness, adjusting the slider in Gnome gives me 16 distinct brightness levels but the keyboard buttons only hit 9 total, skipping a few in between. For volume it adjusts 6-7% every time I hit volume up/down and I'd just like a smaller step size (3-4% probably). I've dug around Gconf-editor a little bit, but I've been pretty unsuccessful finding anything useful. Anyone have an idea?

I've got another problem. In my .bashrc file on my local machine, I have an alias "wf" set up which ssh's into my webfactional account. I have another bashrc set up on my remote machine which works fine when I log in using an interactive shell:

code:

chris@chris-comp:~$ wf
Last login: Mon Aug  3 13:32:34 2009 from 173.88.27.30

But if I do it this way:

code:

chris@chris-comp:~$ wf 'bash-alias'
bash: bash-alias: command not found

How can I fix this? Google came up with two solutions: rename .bash_profile to just .profile, which did not work. And the other is to have:

code:

if [ -f ~/.bashrc ]; then

in .bash_profile, but that was already there. Help?

An easy way to do it would be to make wf a shell script instead of a bash alias, that accepts a command line argument to pass to the ssh command.

your original problem is likely due to your .bashrc having logic to abort if $PS1 isn't set, so it doesn't matter if you source it from .bash_profile for your noninterative ssh invocation. change bashrc or add explicit bash -ilc bash-alias to you wf alias.

I like to browse my files in detailed list mode but nautilus annoys me because I can't just right click an empty space and create a folder/paste, it insists on auto-resizing the columns to fill the screen and selecting the item even if I click on the empty space. Like so:

It's stupid but I've been using windows for so long I'm used to explorer's right click menu and I'm just wondering if there's a way to duplicate this behavior in nautilus? There's no problem in the icon views since there's plenty of empty space but I prefer to browse nice simple traditional lists. :downs:

You'd put this in your ~/.ssh/config

code:

Host wf
  User nbv4
  HostName webfactional.com

On the remote machine, make the bash alias into a executable shell script in HOME.
Then you can do:

code:

ssh wf ./what-used-to-be-an-alias

Using ~/.ssh/config for ssh 'bookmarks' is pretty handy, since then you can easily do stuff like

code:

ssh -t wf vim

to run vim on the remote machine (the -t switch is used to force a pseudo-tty which is needed for screen based CLI tools)

Not sure if this warrants its own shiny thread so I thought I'd play it safe and ask here first.

Backstory: We are a hosting/managed IT/remote backup company. We're working to implement Alfresco, running on CentOS, as an enterprise content management solution for a bunch of new clients. We host and manage, they access and do goofy things with their documents. So far so good.

My company wants to give its clients remote access to the Alfresco file share through SMB/CIFS. Over the internet. I have gathered that this is a Bad Idea.

What alternatives, if any, do we have to work something like this?

Honestly, if you are that far lost with DNS and aren't willing/able to do the research to even get started, you probably shouldn't be hosting your own DNS. zoneedit.com is a commonly used free DNS host that you can use to point your domain name at your server.

If you really want to host your own DNS, the first step is to read up on the basics of DNS and how it works, and then move on to possible DNS servers such as BIND and djbdns, and the "crazy poo poo" you have to do to get it running.

edit: Sorry to sound snarky, but if you are just getting started with Linux/systems administration, there are other places that you should start before setting up your own DNS server if the guides you are finding on google are just total nonsense to you.

I already pointed you to an easier way to go about it than setting up BIND. Head over to zoneedit.com and you can have them host your DNS for free.

The reason why I didn't type up a guide to setting up BIND is because there are literally dozens out there already that are very in-depth. If you had attempted to follow a guide and hit a stumbling block that would be easier to work with, instead just coming in and asking how to do it from start to finish, what do you expect someone to say?

Ok, now I do have a problem. I added TightVNC to my startup applications by adding the command 'tightvncserver' to my Startup Applications Preferences.

The way I can tell that a server starts via this command, is that I hear the 'startup' sound twice; once for the desktop, and again for the TightVNC desktop.

But I just booted my computer with this as a startup application for the first time, and it will not stop executing this command. tightvncserver keeps re-executing itself. How to I make it only execute one launch on startup?

Edit: I figured this one out on my own too! I gotta add ':1' to the command, so that when it runs the second time, it sees that the :1 desktop was already made, and thus the loop stops.
