Debian Multimedia :: KMyFirewall Does Nothing \ Cannot Run It Due To The "iptables" Command Requiring Root?
Mar 19, 2011
Alright, I'm trying to use KMyFirewall on Squeeze and it doesn't do anything. Whenever I do something that's supposed to require root access, it does not prompt me for the root password and as such, it doesn't work. For example, I setup a basic firewall that only accepts established and related connections coming in, and cannot run it due to the "iptables" command requiring root. This means that when I press the button to run the firewall (not install, run) nothing happens.
I believe this is related to the bonehead move to remove or cripple kdesu in Squeeze and/or KDE4. Is this the case or is something else wrong here? I would like to run a personal firewall on my laptop without spending a day and a half writing rules by hand. I'd also like to quickly poke holes in it for applications when needed, so please don't say something stupid about doing it by hand. I'm looking for help with a program that appears broken in the stable release.

I ve noticed that iceweasel (3.5.13) is slow in some java requiring websites: showcase: [URL] then add in the field location more than two locations (3=max i think). notice the slughiness if not the IW rash. Trying the same with epiphany (2.30.6) is (much) bettereventhough the cpu usage is also getting high System: Linux debian 2.6.32-5-686 #1 SMP Tue Oct 19 14:40:34 UTC 2010 i686 GNU/Linux at Gnome Desktop

In our group we use NIS and have a group set up called netadmin which is given root privileges on each machine. Each machine also has a localuser called localuser created and used during installation. When logged in as a member of netadmin, attempting any action that requires root privileges (e.g. installing software in Ubuntu Software Center) results in a prompt asking for localuser's password, not the current user's password.
Does anyone know the cause? Configuration issue or Ubuntu issue? We can get around it.

I have one Centos Server and I want to forward root mail to 1 external account: [URL] I installed sendmail and created /root/.forward with this content: [URL] and I sent a test mail with this command: /usr/sbin/sendmail root <prueba.txt But nothing was forwarded.
After that I ran the same command with the verbose option:
/usr/sbin/sendmail -v root <prueba.txt
And this is the output:
root... Connecting to [127.0.0.1] via relay...
220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Nov 2010 21:09:39 -0600
>>> EHLO localhost.localdomain
250-localhost.localdomain Hello myfriend [127.0.0.1], pleased to meet you

[code]....
For some reason sendmail tried to connect to example.com smtp server and couldn't reach it. I am sure this is because the smtp server for example.com domain is not example.com is mail.example.com. Besides mail.example.com requires authentication, username , password and the smtp port is not the default 25 is 9999. configure sendmail to forward root mail to a smtp server that requires authentication, username, password with a not the default 25 port?

I've installed it properly until it works now, it does send emails and receive them, but heres the problem.
1) it does not send emails to a certain domain, unless i do dpkg-reconfigure on exim4 and put the domain on allowed relay... can't i just put something on settings which allow to send emails to ALL domains?
2) EVERYONE can connect to the server by telnet from any position, terminal or pc, and just use an existing user to send emails to anyone.... example, i have testuser123 setted up in debian/exim4 .. then they simply write "mail from:testuser123@host.dot" and the server accepts it.. without even request an authentication for that. And this is a problem, because everyone can use my email addresses to send emails to whoever.. heaven for spammers/hackers..

I have the eight Debian dvds listed in my sources.list, along with security, nonfree, and multimedia repositories. It does this for all eight dvds, re-scanning them for the update.These dvds have already been scanned (from the apt-cdrom add command). New updates are NOT going to suddenly appear on these already scanned dvds, so this is a completely unnecessary endeavour.Is there a way to stop this?It didn't happen with Lenny, and I'd like to stop it with Squeeze.

I am using Debian Jessie x64 with XFCE 4.10:
Code: Select allnickolay@nickolay-pc:~$ uname -a
Linux nickolay-pc 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-2 (2015-04-13) x86_64 GNU/Linux
And am having a problem with dockbarx.
Whenever I try to launch it as a regular user, I get:
Code: Select allnickolay@nickolay-pc:~$ dockx
DockbarX 0.91.4
DockbarX init
DockbarX reload
Restarting DockManager Helpers failed.
Traceback (most recent call last):

I tried reinstalling the packages, but this did not work:
Code: Select all sudo apt-get purge dockbarx*
sudo apt-get install dockbarx dockbarx-themes-extra
sudo apt-get install xfce4-dockbarx-plugin
The system is upgraded to the latest available packages in the repositories.

To use most of my Kali applications, I want to be able to log into an X session as root. I know it is generally a bad idea and I don't want to do it as a rule, but it is useful for penetration testing (e.g. nmap and its GUI don't have most of the useful options when run as a regular user).
So how do I get GDM3 to allow me to log in as root? Currently, if I type in the user name "root" and log in, it just takes me back to GDM3. Could it work to add root to my user group (I really don't want to add all kinds of security holes)?

I just installed Lenny base and added Fluxbox as wm. I can start Fluxbox from root with "startx" command but only get a light blue screen that is frozen if I try to start Fluxbox from the command line user ID using "startx." I think that it might be an ownership problem but I'm not sure what files I should change the owrnship of, if any. Some of the in installation of fluxbox was done from the root directory instead of from the user directory using the sudo command.

I'm on Squeeze with KDE 4.4.5. Basically, I can use my password for things like logging in, or authenticating on a shell with sudo successfully. But in other cases, I am asked to "become root", and when I enter my usual password, I'm told to check if I entered my password correctly. This happens with Aptitude (terminal GUI), for example: from Actions, I try to update the package list, and when I enter my password, I can read su: Authentication failure. However, if I start Aptitude by typing kdesudo aptitude on Konsole I can enter my password in the authentication box successfully, and use Aptitude with administrative privileges.
The example is valid also for other applications, such as System Monitor: just for the sake of the example, if I try to stop a process owned by root, say Aptitude, I'm asked for a password to become root, but my password doesn't do the trick. I'll have to open it from terminal with kdesudo ksysguard, then I'll be allowed to kill that process. Does it have anything to do with my choice at installation? I think I must have chosen to leave the root password field blank, and only entered my password as a user, for it explained I could become root anytime if there was need to with sudo.

I have just installed Lenny on a Thinkpad R50p. During the install I opted for no root password, using the sudo option instead (I've been used to this on Kubuntu for a long time). After installing, I added KDE 3.5 with apt-get install kde-desktop - all seems to be OK, except that I am unable to add packages or perform tasks for which a root / admin password is needed. It seems that the install-time choice of sudo (shared password) does not propagate to the KDE install, which is still expecting a root password.
how to either enable the KDE desktop to work with this shared password setup, or whether there is a better route to a KDE 3.5 desktop than just installing as I did (I am aware of Trinity KDE 3.5 but the Pearson Computing source is still not up, are those packages available for Lenny anywhere else, and are they recommended?). I can of course rerun the whole install and choose root & user passwords but if there is a smarter solution it would be less of a 'reinstall Windows' type of fix
I've had a very frustrating time the last few months trying to find a KDE4 based desktop that is stable enough and not lacking some basic functions (print manager, for goodness sake), so I have temporarily thrown in the towel and will try a Stable installation that is not changing (breaking) all the time, until KDE4 series gets past this adolescent stage of development and settles down.
I do need to get back to a system I can work on rather than keep on trying different installations!

I am attempting to launch kate via kdesu as well as from the command line and it fails both times. I have (after the first failed attempt) coppied my .kde folder to /root and still am not able to launch it (it works fine under my login). The following is what I get after removing my personal .kde folder from root and launching kate: kate(16689): Session bus not found
KCrash: Application 'kate' crashing...

gpsbabel has always been a little awkward to get going, but it works well once it does. Out of the box on Lenny, gpsbabel just gave errors for me reading from a garmin unit, and the required solution was two steps: firstly, remove (and blacklist) the kernel module "garmin_gps". Secondly, add a udev rule like this:SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="0660", group="plugdev" and save this as /etc/udev/rules.d/51-garmin.rules.
Now, I never understood why or how that worked, but it did (on Lenny), straight away, and was listed as gpsbabel's solution here (I notice it now says MODE="666").
Anyway, now I'm on Squeeze and have the same problems again. I've blacklisted garmin_gps again, and it doesn't appear in lsmod.
I've still got my udev rule, but now gpsbabel fails as a normal user with the error:

I have headless debian as a server which i use over tightvnc server running on it. Vnc works fine but I can't for example run sudo mousepad or any other gui app from terminal, it says something about not having the rights to open it as root. I understand this has something to do with security, but my computers are behind nat so the vnc server can only be connected inside my lan so i don't mind.

I installed Jessie with Cinnamon alongside Win 7 - all went quite well though I did have to do a bit of guessing along the way.
Following online tutorials etc, I tried to install sudo from the terminal. It did not go well - some stuff appeared that was not shown in the instructions from many sites. So I abandoned it, or so I thought.
Then I discovered that my root password was no longer recognised. So I reset it, following online instructions.
This was successful apparently, as I can log in as root and see this in the terminal.
But on trying to start Synaptic ( and later others), I found that the new root password would is not authenticated, but my user password does authenticate successfully. This seems to be the wrong way round!

I recently "upgraded" to the latest skype and now every time I open an interactive root shell, up pops skype. I can close skype then control-C in the terminal window to get the shell I want, but this is annoying to say the least. Maybe my google-foo is off, but all I can find is articles on how to run skype as root, which is no use. I've tried searching the startup files for "skype" (case independant), but so far all I can find is "LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/ /usr/bin/skype" in the root .bashrc which shouldn't be starting the app.
what could be causing this?

I just decided I'd give Google Chrome a try. Installed it via the google repository and it went fine.
However, every now and then it just vanishes from my menu and it can't be found again, also the command in the terminal can't find anything.
So, what's left is to reinstall it, and during reinstall it doesn't even whine about already being installed.
Anybody else with this matter? I am running 64-bit Squeeze.

Anyone know if the iptables-restore command operates atomically? I want to make sure that the entirety of in-kernel iptables are switched over to those specified in the input to iptables-restore, all at once, with no intervening emptiness, incompleteness, or mixing with prior table. The man page doesn't say about this.

Env: Lenny LXDE
[Question]
By (first step) doing: pcmanfm --set-wallpaper /point-to-new-wallpaper, it change the configuration to the new wallpaper, then, my question is: What is the most correct way to "refresh the desktop screen" (by command line) so that the new wallpaper is then displayed.
And by (second step) doing: lxsession-logout, and choosing 'Logout', the new wallpaper is displayed after the new login. No problem here. Is there a (most correct) way to completely change the picture and activate it by command line (without user intervention)?

I have a problem with my 64-bit version of Debian Linux Lenny. I have to run alsaconf every time I boot into the machine. I have tried to run this command followed by alsaclt store. It was no help, I still have to run the command every time to get sound, which makes it very annoying. Anybody know what configuration file I should be looking at, and what I should be changing. If you need a print out of any of my configuration files, just let me know what they are and where they are and I will post them. The sound was working fine for the longest time before, I think the whole mess started when installed KDE, E16, XFCE etc. I was trying out these new windows managers and seeing if I would like them. I don't really like them all that much as the gnome so I removed them.

I recently did a reinstall on my system and I am now running Squeeze. I am currently trying to get some software running, but I believe I am having issues with the graphics requirements. The software needs an X server with 8 bit / PseudoColor mode. It is recommended to work in "8,24"-overlay mode. This was set up on my old install on this computer, so I know it is not a problem with my graphics card. But in the installation guide it says to enable this function it is necessary to add some information in the file /etc/X11/XF86Config-4. The problem is I don't have this file. I had this file in my old install, but on the fresh install it is not there. I have the /etc/X11/ directory, and it contains: directories: app-defaults, applnk, cursors, fonts, twm, xinit, xkb, Xreset.d, Xresources, Xsession.d
and
files: default-display-manager, rgb.txt, X, Xreset, Xsession, Xsession.options, XvMCConfig, Xwrapper.config
I think I've looked through everything in the /etc/X11/ directory but I don't see anything that looks like the XF86Config-4 file. Is there possibly a package that I am missing or something I need to run to create this file? I know on my old install this file was created or modified by running 'xf86config' in the command line. I've tried that, but it tells me 'command not found'.
