General :: PuTTY And 256-color - Line Drawing Characters ?

May 3, 2011

I'm having trouble setting up PuTTY with Ubuntu. I'm trying to get line characters to work in aptitude as well as 256-color support, but can only get one or the other.

Ubuntu Config:

Using 64-bit Ubuntu
Terminal type xterm-256color or putty-256color gives 256-color, but incorrect line characters.
Terminal type linux gives proper lines in aptitude, but only 16 colors.

PuTTY Config:

Using font with Unicode characters. (DejaVu Sans Mono)
Received Data is assumed to be in UTF-8.
Set to use Unicode line drawing code points.

Slackware :: Dhclient Does Not Strip Or Escape Shell Meta-characters

Apr 6, 2011

dhclient does not strip or escape shell meta-characters

Summary: dhclient doesn't strip or escape certain shell meta-characters in dhcpd responses, allowing a rogue server or party with with escalated privileges on the server to cause remote code execution on the client.


ISC dhclient did not strip or escape certain shell meta-characters in responses from the dhcp server (like hostname) before passing the responses on to dhclient-script. Depending on the script and OS, this can result in execution of exploit code on the client.

CVSS Score:

For more information on CVSS scores, visit [url]


On SUSE systems, it is possible to disable hostname update by setting DHCLIENT_SET_HOSTNAME="no" in /etc/sysconfig/network/dhcp.

Other systems may add following line to dhclient-script at the beginning of the set_hostname() function:

In environments where filters/acls can be put into place to limit clients to accessing only legitimate dhcp servers, this will protect clients from rogue dhcp servers deliberately trying to exploit this bug.

However, this will not protect from compromised servers.

Active exploits:


Upgrade to 3.1-ESV-R1, 4.1-ESV-R2 or 4.2.1-P1. [url]

No patch is available for 4.0.x as it is EOL. Anyone running 4.1.x should upgrade to 4.1-ESV-R2.

Ubuntu :: Setup A Putty Session To Putty From One Machine To Another?

May 15, 2010

I am trying to setup a putty session to putty from one Ubuntu machine to another. I know how to setup to connect to the machine from Windows and I am using the same settings for the one I am trying on the Ubuntu machine but it fails to connect. It fails immediately so I believe that putty is not able to find ssh. Is there some configuring that I need to do.

General :: Convert Shell Logs - Incl. Escape Characters - To HTML?

Mar 6, 2010

Is there tool or a regexp that can convert shell escape characters to HTML code?

As an example, here is a logfile from GNU screen:

Which I would like to convert to something like this:

And send as HTML e-mail to an e-mail address, to archive my work.

Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.

Ubuntu :: Delete All ASCII Characters In File - Leave Chinese Characters Only

Jul 8, 2011

What command could I use in terminal to delete all ASCII characters? That is, delete a-z, A-Z, 0-9, and all punctuation? I have a file containing Chinese characters, and I want to remove everything else and leave just the Chinese.

I can use grep to leave only the lines that have Chinese in them, but this still leaves a lot of non-Chinese stuff on those lines. Does anyone know how I could actually remove everything that isn't Chinese?

General :: Does Non-printing Characters Escape Characters Still Needed For PS1 Definition?

Aug 28, 2011

While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?

Ubuntu Servers :: Runlevels In Or The Lack Thereof?

Jan 23, 2010

I came up on RedHat. While I thoroughly embrace Ubuntu now, I miss the concept of runlevels. I installed all my CentOS servers with Gnome as a convenience on tap when needed. I boot them to runlevel 3 and open a vnc shell if i need gui. Then kill the vnc thus killing the gui. Just a fantastic compromise for me.

SOooo...how to replicate this behaviour in Ubuntu?

NOT a very broad topic on here that I can see. Anyone doing this? How?

Ubuntu One :: SubAir Does Not Work Due To Lack Of SSL Support

Jun 24, 2011

It's a long long story how I got to this point but I'll save that for later. Ubuntu says subAir does not work due to lack of SSL support. That's only one reason why it doesn't work. I've gotten past that and a few more issues. Here is what I've done: Used stunnel to get around the SSL issue.stunnel -c -f -d -r streaming.one.ubuntu.com:443

subAir still will not work and return a 403 because it wants to do a GET /I got around that two ways. One was a reverse squid proxy and another was an Apache proxy. Ok, now we're cooking. Except now subAir is sending POST data to the subsonic server and ubuntu's version does not seem to like that. Try it yourself

curl -d "c=myapp" https://streaming.one.ubuntu.com/rest/getIndexes.view -v
curl https://streaming.one.ubuntu.com/res...s.view?c=myapp -v

sigh.... so here I am thinking about writing a POST to GET 'thing' or maybe we can get some more info on how ubuntu's subsonic api works.

Ubuntu Multimedia :: Digital Media Connection ( Well, Lack Of )?

Jan 18, 2010

I've trolled the forums for about 30 mins or so already looking this up, but can't seem to find any solutions. Most threads seem to end with either a "report to launchpad" or they just end without resolution. So in case I've missed a solved thread:

Plugging my Kodak C503 in gives inability to mount due to lock issues, the infamous -60 lockout. However, I get TWO icons in metacity, neither are mounted/will mount. Turning the cam off removes both, and I can't get down to only one. Not sure if this is because it's reading the camera's internal memory + my SD card.

So, I pulled the SD card out, and jacked it into my card reader in my lappy. no dice. In fact, none of my SD cards work; leading me to believe I need to find drivers for it.

Notes: (1)It's a Pavillion ZD7000 (2)nothing pops up in fdisk (3)I really don't want to load up windows

Ubuntu :: Mysterious Lack Of Connectivity After Server Reboot?

Jun 23, 2010

Every time I reboot my server, it no longer connects to the internet. It is dual-homed with an internal and an external interface. Both come up. The internal connection works fine. Nothing happens on the external interface. Ifconfig shows that both interfaces are setup correctly. My iptables settings are properly restored. Forwarding is automatically enabled. For some reason packets do not go anywhere on the external interface. This has been true ever since the upgrade to jaunty I think (now running lucid).

Once I restart the external interface it works perfectly (eg ifdown eth1; ifup eth1 or /etc/init.d/networking restart). The problem only occurs after a reboot and only occurs on the external interface.

Here's my /etc/network/interfaces file:

# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static

Ubuntu Installation :: Partitioner Lack Slide Control?

Jul 17, 2010

i remember back a few years ago you could partition the drive by simply sliding a slider, and now trying to install ubuntu next to xp my dad was unable to set it up. This is a big step back for the design of the partitioner. He was able to set up ubuntu 7.04 on his old computer many years ago when i was not there. He tried to set up 10.04 today and got so frustrated with ubuntu wanting to take most of his drive, that he gave up. why was the "simple slide to set space you where going to give ubuntu" taken away. he just wants to set up the space he didn't want to deal with root, swap space, and so on. he just wanted to set up a block of space that ubuntu can use however it wants. but the partitioner will not let him. this needs to be fixed. the install process must be simple to use by everyone. i do not want my friends and family getting frustrated with installing it. he was excited to try the new ubuntu till he got to dealing with the partitioner and after that he wanted nothing to do with ubuntu. the installer is the first thing they see make that the primary focus of "easy of use".

Ubuntu :: Resize Partition Scheme Lack Of Knowledge The Cause?

Jan 26, 2011

I setup a dual boot system, with approximately 200gig planned for ubuntu 10.10. Based on the article here:[URL]..And this quote:


# sda1 Recovery Partition, unchanged
# sda2 Windows partition, shrunk preferably from inside Windows, hopefully about 30Gb
# sda3 Primary Partition, 10Gb, file-system = ext3, in the Partitioning Section of the installer change the "Mount Point" = /


I assumed at that point that the "sda3" "/" would be for booting purposes. I would have to guess that I was wrong, because it is filling up very quickly. As you may be able to tell by the screen shot, "sda5", "/home" was what was assumed to be the file structure to store all of the programs and such.

I have only been running this setup for a week, and would expect to not be seeing my "boot" partition growing so quickly. Do I need to resize it? here do the standard programs that I get from the ubuntu software center install at (partition wise)? I suppose I dont mind wiping that section dry and starting over, but I would give a resize a try if possible.

Fedora :: Yum Complaining About Lack Of Space On /boot?

Jan 20, 2010

I've been trying to run a simple `yum update` for the last couple weeks, but it barfs before it finishes every time. For every single package it will say something similar to "('installing package libdrm-2.4.17-1.fc12.i686 needs 208KB on the /boot filesystem', (9, '/boot', 212992L))"

Here's an example of the output:

Running rpm_check_debug
Running Transaction Test
Finished Transaction Test
Transaction Test Succeeded


This is a machine that I recently put through several upgrades: Fedora 9-> Fedora 10 -> Fedora 12. The computer has been working well for the most part, with some minor bugs here and there. Yum updates were working just fine until this popped up.

Fedora Installation :: Total Lack Of Sound With F13?

May 27, 2010

Just installed fedora 13. Everything is great except for the total lack of sound. I'm trying to use the onboard audio. Motherboard is asus M4A89TD. In alsamixer all of my devices are turned on to max.

$ lspci | grep Audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
05:00.1 Audio device: ATI Technologies Inc HD48x0 audio

$ lsmod
Module Size Used by

fuse 54749 4
ipt_MASQUERADE 2208 1
iptable_nat 5420 1
nf_nat 19059 2 ipt_MASQUERADE,iptable_nat .....

When I open pavucontrol, under output devices it lists 'HDA ATI HDMI Digital Stereo (HDMI)' and 'Internal Audio Analog Stereo'. I think the correct device needs to be the the ATI SB one, but is missing from the list.

Ubuntu Installation :: When Go To Edit The Partitions - Won't Let Do Anything Due To An Apparent Lack Of A Root Filesystem

Mar 28, 2010

I'm having trouble installing it on a "new" computer that I found at Goodwill for $60 with no operating system on it. When I go to edit the partitions, it won't let me do anything due to an apparent lack of a root filesystem. (I know this issue has been brought up and resolved in the past, but the usual solution (going into the validation.py file) isn't working for me, as there is no line in this one that says "if not root".)

General :: Lack Basic Understanding Of Permissions (Apache)

Apr 8, 2010

I am very new to linux. The first time i ran a linux machine was one Saturday. Anyway I am trying to set up an apache web server, all I want to do is play around with html and post it on my unbuntu server so it is available to the internet. I am also trying to install samba but I am having trouble with that so for now I am using winscp. Ok, so I made a folder in my home directory for webstuff, and set up apache to look in that folder.

mkdir /home/username/webstuff
I put my index.html file into the /webstuff folder.
But when I go to my website, it says 403 error unable to access "/"

Did I make the folder in the right place? I do not want people being able to access my / folder so maby I made the web stuff folder in the wrong place? Also I thought I would just put my inded.html file inside of the default one apache gives you, but when I tried to transfer index.html it said permission denied. How to set up permissions so I can use apache and transfer my html files from my remote desktop to my server would be great!

OpenSUSE Hardware :: Radeon Driver Opengl Support ( Lack Of )?

Sep 20, 2010

I'm an owner of a ATI mobility radeon X1300 card. Since ATI tagged my card as legacy, i'm stuck with the open source radeon drivers. Wich doesn't bother me, as i know they are slower and openGL support doesn't equal fglrx. What does bother me is that the current version 7.9 dev. claims to have full opengl support up to 2.1. I'm trying to use a extention that is part of the openGL version 1.3 and it's failing. This is a known issue for a long time now and it really disappoints me. "Compressed textures" is what i'm talking about.

Is there any way to make sure that drivers aren't tagged with something they support if they obviously don't? I guess the KDE4 kwin vs drivers thing is the same as i'm trying to say now. Drivers should be documented with what they effectively support and not what they should support. What can I do to make this public to xorg developers? I could only think about posting this here as i have no idea where to put it elsewere. Could someone please point me in the right direction to where i should send this complaint?

General :: GRUB-2 Bootloader Fails To Load For Lack Of Floppy Drive?

Jul 21, 2010

2010.07.21 while trying to install Ubuntu 10.4 I've been trying to install Ubuntu 10.04 on my Dell workstation and am unable to get the Grub-2 bootloader to load properly. It seems to be failing for lack of a floppy drive on the system resulting in an error message that reads : error: fd0 cannot get C/H/S values.

I've gone through the Grub-2 page at [URL].. to no avail and other sources having similar problems have likewise turned up no solutions. here's the background: A while back I was trying to install a different version of Linux and had the same problems, then had to set the project aside for a bit. I don't think this has anything to do with Linux or Ubuntu per se, but rather Grub.

The system is an old (4-5 years) Dell workstation that has one drive (128 GB) set up for Windows XP and a second new drive (500GB) which I installed for Linux. There is a DVD/CD drive and the system contains no floppy drive at all. In one attempt to get this working I tried modifying the BIOS to indicate there was a floppy drive - this created a failure earlier in the chain with the BIOS failing to load properly, not unexpected, just a shot in the dark at that point.

At the moment I am considering just running out to buy and install a cheap floppy drive to see if that helps. I'll never use the thing though so I'd rather find a solution that doesn't require me to spend money on useless hardware. In any case, here's the /boot/grub/grub.cfg contents:

# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
### BEGIN /etc/grub.d/00_header ###

Ubuntu Servers :: Get Sobdomains To Work Fine On A Test Mache, But Domain/site To Work Due To Lack Of DNS Support At The Moment?

Feb 6, 2011

I'm not to sure this is the place I should post this, but couldn't find any place for it to fit. So here is the deal..I am running 10.10 with the standard LAMP setup. I am running a drupal 7 site no problems. What I need to do is run a multi site sub directory. (domain.com/newsite). So far the best I can do is get a directory index of the second site (domain.com/newsite), but cant run the installer. (I did the symbolic link to the doc root of the drupal install.)If I type in the url domain.com/newsite/install.php I get not found. I placed an index.html test page and it renders fine. I think I'm close but just not there yet.

Any ideas from anyone? I can get Sobdomains to work fine on a test mache, but sadly I need the domain/site to work due to lack of DNS support at the moment. I tried to get some info from the drupal forum, but everything always points to subdomin setups. I also posted over there, but it seems like the forums have very little support and are a bit on the slow side.

As a result I am not able to listen to any audio file due to lack of corresponding audio driver programs. make proper configurations settings so that I can listen to audio files in Linux Mint version 10.

I was over in the Desktop forum yesterday and apparently 'event sounds' are available for Xfce and are part of the original package, but I've never seen them made available, that is, the switch to turn them on isn't where it is suppose to be, in any Slackware specific package of Xfce.I've used 4.61 that came with Slackware64 13.1, 4.61 from the Salix depository, 4.62 from Mr. Workman, 4.62 from 'current' and recently 4.8 from Mr. Workman. None of these make the 'event sounds' available.
