Networking Issue & Other Minor Issues

[Killians31]

Hey guys,

I am still pretty new to Backtrack, and am having a few issues that i hope you can help me out with. I seem to be having issues with getting into wicd to connect to a wireless or wired network for that matter. This used to be working, however i was playing around a bit cracking our 128 bit WEP key at my office for security reasons, and ever since then, backtrack wont seem to start wicd or my network connection. This is my major concern out of all of my issues.

Also, another issue i am having is getting applications via the CLI with the syntax apt-get. I have tried to do an apt-get install dist-upgrade, as well as apt-get install upgrade, apt-get install update, but i seem to be getting some errors. (This was all before my networking issue, when my network connections were working). I have all of the repo's selected within the software sources. I am trying to install iperf for throughput testing, as we use it very frequently at my work.

One more very minor thing, i was playing around with customization, and selected something which puts a (mac os - like) toolbar on the top of the screen. This toolbar takes place of the file menu within applications. I would like to take this off, but cant remember what i did to select it .

I would like most to get most of these issues worked out before i make backtrack my primary work OS.

ANY help is GREATLY appreciated!!

Thanks,
Ben

What have you done to start WICD? Because just clicking on WICD in the BT menu won't work.

Also, another issue i am having is getting applications via the CLI with the syntax apt-get. I have tried to do an apt-get install dist-upgrade, as well as apt-get install upgrade, apt-get install update, but i seem to be getting some errors.

You've got the syntax all wrong. "apt-get install <something>" is used when you want to install a program, like vlc (apt-get install vlc). If you want to update/upgrade/dist-upgrade:

apt-get update
apt-get upgrade
apt-get dist-upgrade

You're just being lazy... Open BT4 control panel and look for the option.

I would like most to get most of these issues worked out before i make backtrack my primary work OS.

From what I've seen in this post, maybe you should re-think that move. Ubuntu sounds better for now, move on when you feel more comfortable. This is my advice.

I have been using the command start-network from the terminal to get the network started, which used to bring up wicd in the toolbar. Even when i click on the wicd application, or type wicd in the task launcher, nothing comes up.

it looks like i mistyped the syntax on the apt-get upgrade and update and dist-upgrade, i was running the pre-final edition of backtrack prior to the release of the final. I used these commands to upgrade my system. I was debating on just doing a fresh installation, but i wanted to see if the upgrade would work first.

I currently am running windows seven, snow leopard, ubuntu, fedora, and backtrack. I am defiantly much more familiar with the newer versions of ubuntu gnome, which can always be a fallback option for me if i get stuck in backtrack, but like i said i am still learning much of backtrack.

p.s. i loaded up the live dvd this morning to see if it was my laptop, or something i have broken within the operating system, but i was unable to load up wicd as well.

Thanks for your help

Try the following: airmon-ng stop wlan0 (thats if your wireless interface is wlan0) not sure if this command is needed, i just had issues with my card

then: start-network wlan0

then open Wicd Manager

Before startx, run "/etc/init.d/wicd start". If you want WICD to start automatically every time you boot up BT4, type "update-rc.d wicd defaults" after the previous command.

I believe you will be greeted with some error messages. Best move would be a fresh install.

I have tried this method before with no success, thanks for the tip though!

Before startx, run "/etc/init.d/wicd start". If you want WICD to start automatically every time you boot up BT4, type "update-rc.d wicd defaults" after the previous command.

I currently have start-network set up to start as soon as i boot into BT4, i tried this method as well, but unsuccessful.

During my initial boot up, all of the POST tests pass fine, except i do get an error:

'starting DHCP server: dhcpd3* check syslog for diagnostics'
'failed!'

I looked in my system log (/var/log/log), but i was really able to distinguish what the exact error was. Have you ever seen this before?

Thanks again!

Hey guys, i seem to be having some issues with getting my internet connection up and running in backtrack.

During my initial boot, i receive an error which states:

DHCP server: dhcp3 failed!
Check syslog for diagnostics

I did a bit of debugging from the command line, however i seem to be stumped at this point.

When i initially boot, i perform the ifconfig command, and all i see is the lo address listed.

I then performed the ifconfig wlan0 up command, and i will see all of my interfaces when doing ifconfig again.

When i perform the '/etc/init.d/dhcp3-server restart' command i get this output:

Stopping DHCP server: dhcpd3 failed!
Starting DHCP server: dhcp3* check syslog for diagnostics.
failed!

Looking into my syslog, i am seeing the following errors when performing the above command:

Mar 25 05:48:04 bt dhcpd:

I did a bit of poking around in the /etc/dhcp3/dhcpd.conf and dhclient.conf file, but wasnt too sure what to look for.

Any help would be GREATLY appreciated!

Thanks,
Ben

Do not start a new post on the same topic. Use the edit button.

As for your "problem"

]Mar 25 05:48:04 bt dhcpd: Not configured to listen on any interfaces!

This part seems pretty relevant to me. Now would be a good idea to check the thread in the how-to section on getting networking started in BT.

I agree. I do not know why and I don't know if it's a bug or not but what I have learned through trial and error is this.

When using WCID and BT4 *sometimes* you can click on Service/Network/Start Network from the menu and then WICD and it works. Other times, you need to drop down to a terminal session and type in the command to start network manually then use WICD.

Again, I don't know why this is the case but after spending hours tearing out my hair and posting on different forums I found this to be true. Most often anymore I don't even try to start it from the menu, I just drop down to the command line and start it from there and all my network problems go away.

thanks, Arch.Angel for pointing me in a good direction.

However, i still seem to be having some issues. I managed to get my eth0 interface working, and some of my wlan0.

I ended up uninstalling wicd, as no gui appears when loading the application anymore. I currently have wifi-radar installed, and i can see and connect to access points, however, i dont seem to be receiving an ip address.

I have tried to manually configure a static ip address and access the internet that way, but it still seems unsuccessful.

my resolv.conf is as follows:

Domain DPHoldings.com
search DPHoldings.com
nameserver 10.252.252.15
nameserver 10.252.252.16
nameserver 4.2.2.2

my interfaces are as follows:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp

I still seem to be getting the same dhcp3 error when performing the following command: /etc/init.d/dhcp3-server restart

Any ideas?
