I'm doing this in phases. First up will be basic DHCP serving and NAT stuff. If I can get that going, I'll get Squid, ClamAV and such set up. Somewhere in there, I will also be attempting (keyword there) to set up IPTables. Right now, that seems a little overwhelming but I'm sure I'll get it.

Sounds like a good plan, but your NAT and iptables are probably going to go hand-in-hand. I'll take this opportunity to recommend Shorewall for managing that firewall-type stuff. Yes, if you want, you can learn the arcane internals of iptables, but I personally don't see the point. Shorewall is a script that parses easily readable table-based config files and generates the iptables rules for you. It's hugely flexible, and makes management of more complex rulesets cake. And it's conveniently available in the Arch repository.

I'm trying to hook my cable box up to my computer and I can't quite get the sound figured out. The video out on the cable box goes directly into my monitor. For the audio, I'm running the component out through a 1/8" Y-cable and into the line in on my computer. From there, I'm not sure how to control the sound.

In Gnome (on Gutsy), I can only hear the TV sound when I go to System > Preferences > Sound > Sound Capture > Test. As long as the test is running, I hear the sound. When it isn't running, sound is muted. The Volume Control applet settings only work when I'm running a sound test. When the test isn't running, it doesn't matter whether the line-in channels are muted or not, I get nothing.

So I suppose my question would be: can I listen to the TV audio without running the capture test? If so, how?

If you connected it correctly, you have TV sound at your Line In input. There are two controls -- recording and output mixer. Details differ on different cards, however usually to hear what is immediately on your Line In input you don't have to enable recording from it but have to unmute it, set its level to nonzero, and may have to separately enable output from Line In. You may have to run mixer and go to preferences menu to enable missing controls.

I have no idea how will look an attempt to mount a mis-reassembled or simply wrong device that contains ext3 filesystem somewhere but not at the very beginning. Check if "tune2fs -l /dev/md0" returns anything usable.

Disk /dev/md0 doesn't contain a valid partition table

Give up now?

Looks like /dev/md0 contains a valid ext3 filesystem (journal is enabled, so it's not a journal-less version ext2) and not a set of partitions. The filesystem is either damaged or mis-assembled, however the beginning with the superblock is valid.

First, try to mount it read-only and see if it mounts and allows you to copy files from it. Then unmount it.

After that, if you can, dd it somewhere else, then run fsck on /dev/md0. It may further screw it up, or it may recover the filesystem. After fsck it may mount correctly, or you may have to run "mke2fs -j" on it to create an empty filesystem from scratch.

Was there anything valuable on it in the first place?

You could also specify -p or even -y to do that automatically.

At this point some files may be still damaged -- it will make sense to run something like

code:

find /path/to/filesystem -name \*.jpg -print0 | xargs -0 file | fgrep -v "JPEG image data"

to perform a minimal sanity check.

He didn't specify what directory/files he wanted to do this to. If someone needs to ask about changing simple permissions then they probably are not very comfortable with the operating system. I tend to err on the side of caution.

If the premise is that these files are already _not_ readable by everyone, you should definitely be doing a+r (what if their primary group matches yours?) and ensure every path down to 'dir' has a+rx.

(namei -m might help)

I have a suspicion that you had some copy-protection or virus/rootkit on your Windows installation that messed with your DVD drive. I don't think, it affected Linux, but it would probably do something stupid because you have changed the paritions/bootloader.

I should have mentioned that this problem occurred when I had WinXP installed too. The only commonality between the two installs is that both of the Windows installs were the primary partition.

Some ftp servers will limit the number of items returned when your ftp client requests the list of files in a directory, which has been a pain in the arse for a project I'm working on (mine is limited to 2000).

After not using linux for months, I dusted it off and upgraded from Feisty Ubuntu to Gutsy. I've been pretty happy with the change, and got most of the little problems worked out.

However, I've got something that seems new to Gutsy that is bothering me. I've got a Geforce 6800. I spent over an hour fighting with the nvidia driver, trying to get it to work. I installed it with and without Envy, and tried a number of other options. I finally realized that it was installing correctly, but the monitor setting was at plug n play, so I wouldn't get resolution options past 800x600. I've got an Envision CRT monitor that came with a Compaq or something, and it's not in the model list, so I have the monitor set to Monitor 1280x1024, and then specifically the resolution is 1024x768. I've been having trouble with the refresh rates. No matter what I set them too, my eyes feel like they are straining pretty badly when I read text on the screen. My options are 50Hz, 64Hz, 71Hz and 72Hz. Additionally, restarts seem to put it back to 50Hz. The other settings don't change.

A potentially related problem is with the font rendering in Firefox. Fonts just look terrible. I've got them set to 96 dpi, and I tried messing around in about:config. Making them bigger doesn't really address the problem. I downloaded the Firefox 3 alpha and seemed to get it to look really nice last night, but whatever I did was gone with a restart. I know I have a lot less detailed information here, but it's so subjective and I don't know how to describe what I'm looking for. I want the characters to look full and complete. As it is they simply look like I have LCD smoothing turned on, which I don't, and the different options in Appearances don't help.

I'd like to figure this out because I can't see myself using Linux if looking at the screen gives me a headache.

Edit: changing the hinting to slight seems to helped with the fonts in Firefox a bit, but the refresh issue is still there.

Some ftp servers will limit the number of items returned when your ftp client requests the list of files in a directory, which has been a pain in the arse for a project I'm working on (mine is limited to 2000).

How can I increase the limit or download the files I don't have yet?

An easy check would be

code:

glxinfo | grep direct

from a terminal and make sure it says yes.

There's probably a graphical way to do this, but it sounds like you need to sort out your horizontal and vertical refresh rates - that fixed it for me with a CRT screen that never played nice with the default refresh rates. All options for screen res etc are set in the /etc/X11/xorg.conf file which will not be changed on a restart.

You can look your horizontal and vertical rates up in the monitor manual / internet. Then log out of gnome and hit ctrl+alt+f1 to drop to a command prompt. You can edit the xorg.conf file directly if you wish, but you may find the following to be easiest: Log in and run

code:

sudo dpkg-reconfigure xserver-xorg

All you need to do is basically keep hitting enter for the defaults until you get to the monitor section - then select advanced and input the horizontal/vertical refresh rates as appropriate and the resolutions you want to use. Then save it when prompted and run

code:

sudo /etc/init.d/gdm restart

to restart the X server using the new configuration.

Re your fonts, it's probably rather blasphemous, but installing the msttcorefonts (think that's right) package pulls in all the usual Microsoft true type fonts and may give you better results.

Try editing the file /etc/X11/xorg.conf

There should be a section called "Monitor", in it you'll want to set the values of Horizsync and Vertrefresh. These values should be either printed on the back of your monitor or perhaps on the manufacturer's website.

For reference, here's my monitor section:

code:

Section "Monitor"
	Identifier	"Monitor0"
	VendorName	"ViewSonic"
	ModelName	"ViewSonic A70"
	Option		"DPMS"
	Horizsync	30-70
	Vertrefresh	50-180
EndSection

Edit: Beaten

You can also set resolutions, in the "Screen" section. It should be pretty obvious where you do that.

The limit is determined by whoever hosts the server, so you'll have to ask them :/

For my project, I used the appalling workaround of simply downloading the index.html using HTTP (which apparently doesn't have this limit) in order to get the full list of files in a directory.

In /etc/X11/xorg.conf add

code:

Option "UseEDID" "false"

to the Device section that describes an adapter with "nvidia" driver.

So what do they have to change? Is it just some variable that needs to be set in proftpd.conf? How, specifically, do you set it?

I've tried editing xorg.conf manually and using the GUI, and it isn't working. I change the values to the refresh rates I found in the Windows drivers for the monitor, and when I reload, it uses the vesa driver and a plug n play monitor setting.

Edit: for the time being I looked through the list of monitors and found one with the same refresh rates. I wonder what I was doing wrong though.

Hey everyone, trying to figure out this bash prompt stuff. Anyone know of a way I can set my prompt to a brief hostname? For instance, if my FQDN is butts.desktop.rear end.com, I don't want the prompt to say

code:

[butts ~]

and I don't want the prompt to say

code:

[butts.desktop.rear end.com ~]

But moreso something like this:

code:

[butts.desktop ~]

So far in my research I've found I can use \h which provides the short hostname or \H which provides the too-long FQDN, but what about something to get me the hostname + subdomain? I've done research on the PROMPT_COMMAND variable but that really hasn't gotten me anything useful.

I'm a network engineer, and pretty retarded when it comes to Linux type stuff; I know enough to get me into trouble and that's pretty much it. Thanks for your help here.

I recently installed Ubuntu 7.10 gutsy on my HP nx6125 laptop (ATI radeon 200M integrated video card), however I'm having issues with the display burning my eyeballs. On Windows, ATI had a control panel where you could adjust contrast, brightness, color, gamma, etc. - is there such a thing I can use for Ubuntu?
