General :: Enabling GUFW / UFW In Debian - Wrong Identification
May 24, 2011
I have a problem with the unix firewall (gufw). I'm using Linux Mint Debian Edition. The problem appears when I double click on the icon to bring it up for configuring. Everything is grayed out so I click on the "unlock" button. Normally, this is when gufw comes alive with color. But all I get now is a note on the bottom of the gray screen that says "Wrong Identification". Uninstalling and reinstalling UFW and GUFW didn't fix the problem. I would like to have my firewall working for me.
gufw - transfer gufw rules to a new computer.Set-up over time, a gufw contains dozens of rules.Is there a way to easily copy and transfer these rules to a new computer - without spending hours of setting it up again from scratch, by hand
I tried assuming that the touchpad was a synaptics device and configure it as such, but it wasn't and this caused X to crash. (I also tried piping the output to grep -i and search for some key terms).
Every time I install Jessie, I also install gufw as a graphical firewall frontend for desktop users, but I've also always had to create my own menu icon because the default one never showed up. I opened up the .desktop file today and took a look to see why it was never displayed in Gnome.
There was a line next to the bottom that basically told it to only appear in Unity. Deleting this line allowed it to appear in the Gnome menu. My question is this. Why is this line even in here?
I'm brand new to Linux and perhaps foolishly jumped right into Debian (Jessie). I've managed to get Dropbox downloaded/installed/whatever the proper parlance is, but in order to access it I have to input Code: Select all~/.dropbox-dist/dropboxd. When I close the root terminal, Dropbox disappears.There's no icons in the menu. Likewise with GUFW. It might be superfluous since UFW seems to be active whenever I check it through the root terminal. Is there any way to configure Dropbox to start automatically and maintain its status even if the root terminal is closed? I've looked around these forums and the internet in general and not found any similar problems. Also, I installed Spotify but whenever I click the icon nothing happens.
I have some init scripts that launch some daemons that I wrote. I want Linux to generate a coredump anytime something crashes. I activated coredumps in /etc/security/limits.conf by adding the next line:
* hard core 100000 After rebooting, I run ulimit -a and I can see that coredumps are not activated: > root@computer:~# ulimit -a > core file size (blocks, -c) 0 First, I checked if there is any file script on my system that deactivates coredumps (greping ulimit -c 0 ), but I didn't find anything so far.
Then, I created a bogus c program..to double check if it's working, and I can confirm that it's not. The program is this
I want to use the Control + windows key on my keyboard to do a killall firefox-bin. What I've done so far is gone in to gconf-editor, and under apps->metacity->keybinding_commands I made command 1 as killall firefox-bin and under global_keybindings, run_command_1 I have <Control><Super_L> . What am I doing wrong?
When I try to connect to my SUSE server from other one this appears: Remote host identification has changed. I deleted entry in know_hosts but it still working wrong, showing me this message. What could be the cause of this problem??
Today I first tried out gufw to block some host that constantly tries to log into my FTP server which invalid user names. I managed to change the default rules to allow so that ufw wouldn't block my usual business. Then I added a rule to block all TCP from that IP to port 21. Working fine.
But what is that IN/OUT distinction good for? I specify IP addresses as from and to, so why would I need to also say whether this is in- or outbound? An old Wiki article on ubuntuusers.de is dated Ubuntu 8.04 and doesn't make that difference at all.
I have an older ATI chip card with tv in (both cable and a/v), and would like to build me a video editing box. Is there a utility to query the card, or at least the card's bios??
I really would like to jump into my desktop environment when I start my machine without the need to enter my user name and password. Apparently this is very easy to do. I added the following lines to my /etc/lightdm/lightdm.conf
Code: Select allgroupadd -r autologin gpasswd -a username autologin
As you can imagine, it didn't work. Otherwise I wouldn't be here... I also tried to install Slim and enable autologin adding the following line to the /etc/slim.conf
Code: Select allauto_login = yes
That didn't work either!
Am I missing anything? Enabling autologin in LXDE?
My distro is Lenny. I am struggling with trying to enable .htaccess files. I followed a ubuntu tutorial that did not work at all. How do I enable .htaccess files in all apache2 directories for Debian 5.0 Lenny?
I have encountered a bug in the live-build in Debian Live. The persistence does not work it is because of the bug #767195. I cannot recreate another live img file because of bandwidth problem, is there any way to repack the initrd and enable the cryptsetup?

I have a dell optiplex configured with an extra PCI network card, because I plan to set it up as a gateway / LTSP server, but I have troubles getting the second network card to work. It is recognized during installation (where I can choose the primary network interface) and doing a
Code: lshw -class network
After installation shows both network cards, with network 0 being labeled Disabled. I have tried configuring the other network interface in the /etc/network/interfaces file, but it has failed to work. I have also briefly looked at udev rules, but it seems that it renames the interfaces fine during bootup, as
Code: dmesg | grep "udev" Shows the following Code: [1.138307] udev: starting version 160 [6.003002] udev: starting version 160 [7.237092] udev: renamed network interface eth1 to ethlokal [7.253775] udev: renamed network interface eth0 to eth1
I also noticed a briefly shown "address collision" error of some sort during boot, but it never shown for long enough for me to read it through. The network card that is enabled is an Intel 825662EZ 10/100 ethernet controller, and the one that is disabled is a Realtek RTL-8139/8139C+.
How to enable persistent logging with systemd? I find it really weird that all this machinery that is systemd doesn't store persistent logs, what if I'm trying to retrieve some information regarding previous boots?
For instance: I have random suspend issues, after rebooting the computer there's no trace left in the logs of what happened, and furthermore (at least in Jessie) I can no longer see a pm-suspend log.
So, at first it sounds like all you have to do is edit journald.conf setting #Storage=auto to "persistent" and create the /var/log/journal directory, but then reading here /usr/share/doc/systemd/README.Debian
Code: Select allEnabling persistent logging in journald =======================================
To enable persistent logging, create /var/log/journal and set up proper permissions:
There are two main reasons why I decided to not enable persistent logging just yet ....
We did get corrupt journal files in the past where the journal then no longer worked at all [1]. With volatile you can just reboot and have a clean state again. Admittedly, the journal has seen a lot of improvements in the mean time and hopefully is more robust, so this point is no longer true.
We still install rsyslog by default. That means we get store them twice. This is something we don't want to do atm.
I have a Dell Latitude D400 laptop running Wheezy (I can't upgrade to Jesse at the moment) and I want to try out the Pointing Stick on my keyboard. If you Google "Pointing Stick" you can find images of it. It's located in the middle of the "G", "H", and "B" keys. Now it doesn't do squat so I'd like to enable the Pointing Stick. How exactly would I do that?
I'm not looking to use it full time, I just want to play around with it.
1. computer A connects to the internet through usb dial up modem 2. computer A & B are wirelessly networked through an ADHOC network. 3. computer B doesnot need to connect to the internet.
I've installed the GUFW. If I enable it I can not see the other computer files. I use static IPs for both. I tried setting a rule but I get stumped were it asks for the port. I'm not all that familiar with ports.
Is there a way to use the firewall to essentially lock certain programs like firefox and transmission to my vpn connection-so that in the event that my vpn connection goes down these programs do not use my default ISP Internet connection.
Any1 know of a music player that has support for track identification service like that used in sony ericsson mobiles which records a small part of the song, then uploads it to a server, and identifies the song? or is there an open source service like this in the first place? so maybe id develop a plugin myself?
EDIT: i did find this but it doesn't have linux support
EDIT2: found this 1 is online but it requires me singing , i wonder if theres a way to query it...
Could someone give me the steps to installing/enabling the newest Flash 10 in Debian Testing/Squeeze?I want to install via the steps one would do from Adobe's website.IT DOES NOT WORK.IT DIDN'T WORK FOR ME.I just want to install the routine way that is usually done in Linux but when I downloaded it, I was asked to extract it and I have no idea where it got extracted to.Can anyone help?I don't mind starting from scratch.I don't remember how to do this method.I'm used to the 'non-free' package in the repo but Flash 10 is no longer working so I want to use the 'sure' method.
I installed Squeeze in Virtualbox 4 and I need to enable the main repos for debian after several google searches I gave up. I am sure this isn't the first time this has been asked and I am sure that it is a common question.
I have a netbook and the wireless card on it works fine. Whenever I wake it up after suspending for couple of hours, it seems like the wireless card is not awaking or the drivers are not working properly because I do not see any wireless networks after waking it up(for example in Wicd). If I do fresh restart, the wireless and wireless networks come back at the same place. So I am wondering if it is possible to restart the wireless card or the driver without restarting my netbook
Just want to stealth ports on my laptop. Had problems with firestarter when I installed in on 10.10. Set Firestater back to defaults and then dumped it with:
Code: sudo apt-get purge firestarter Set up Gufw to defaults and now am not sure what I am seeing with iptables. iptables -L shows .....
Do these settings look correct for default settings for Gufw? or do I still have some problems with the old firestarter settings not being removed. All I want is all ports stealthed. I know that ping is enabled but I believe that is a default setting in ufw. Could I restore iptables to default with:
Code: sudo iptables -F and then enable Gufw and set default?
I just installed gufw and was in quite a hurry. A root acces prompt came up as I started gufw for the first time, and I quickly responded with appropriate password. All I saw in this hurry was that it had something to do with the usr/share directory.So, here's my question: Does gufw require root access when first starting up
I think that the biggest problem that I have had is that some of the music (and audio books) that I have gotten have not played on my walkman, or have not been able to be downloaded in to I-tunes.
First: I hate itunes... I only try to make it work because I love my wife. (and do not want her to hit me)
Second: I know that my Walkman has a very limited range of files that it can play, so I will need to convert some types of files.
But my basic questions:
* How can I figure out what format a file is in? * Below that, how can I identify the singular characteristics of a file? (bit rate, and other formats...) * Is there a best way to switch the formats or format options of these files. (I am currently using sox to do this, it seems to very complete)
Basically. I know nothing! The most that I do not know is that two files that as far as I can tell have the same formats, and should work the same never the less, one of them works, the other does not. I am looking to figure out a way to look at these files (maybe they are mislabeled) and figure out what their real format is (and a more complete format than just being MP3 or such) and then to be able to convert it in to a format that is able to be used by myself and/or my wife.
I've one lenovo 3000 g430 4152 laptop on which i have windows but previously installed debian 5.03 and for enabling the wireless i've to download broadcom b43legacy and install it by compiling because the backports kernel doesn't work with lenovo and after installing debian accidently switched of the wireless by the slide button on laptop
but on next boot i was not able to enable the wireless either by the slide button or fn+f5 which is the key for enabling it the wireless then on some forum i got advise that i can only re-enable by installing windows because lenovo drivers are available for only windows for this model... my question is that is there any solution for it in debian and also there is one more problem that i've to press fn+f8 twice on each boot for enabling the touchpad...
When I try to set my number of desktops to "4" on the KDE control module, it reverts back to having only two. I downloaded and installed the current ATI driver (ati-driver-installer-10-11-x86.x86_64.run) and everything works as it should with compiz, except for desktop cube, because I only have two desktops. I never had a problem while running Ubuntu, just with backtrack 4 r2. By the way, I have it installed and not running on a virtual box.
