Network Injectors And Network Sniffers

I believe this belongs in here (newbie) and not in Networking.

I'm completely starting out with networking. I have done some research, but I never ran networking commands in a serious way.

Is there an all purpose beginner guide to getting around a network, and learning basic troubleshooting skills? I'm using Ubuntu 14.04 in VirtualBox running on Windows 7 Professional.

I would like to get an understanding of statistics, how to map out my home network and networks I connect to and so on. So I'm interested in any help, any tips and etc.

Thanks!

Hi Folks,
Installed Mint-mate 17.
It gives message:You are now disconnected" after logging in.
I restart, the network connection comes.
It is not "networking restart", but system restart.

Tried five more times. The behaviour is every time the same.
After booting the system, no network connection. But from there I restart the system, then network connection is on.

Very irritating to always boot it second time to get the network connection up.

The computer is a desktop Dell Optiplex 9010.
On the same computer, Windows 7 runs without any problem.

Any idea how to fix it?

Thanks

I installed Debian 7.8.0 in text mode. While I configure eth0 through /etc/network/interface it assigned the IP but unable to ping to other machine in the network. I tried /etc/init.d/networking restart but still not working for me.

While I install GUI mode, it allows me configuration done through Network Manager and it pings good to other machine.

I have selected base install during the installation.
How to fix it under text mode?

So I'm on the last step of this article to run vmware-install.pl to start installation of my VMware tools and I'm getting this error.

[root@LinuxTest01 vmware-tools-distrib]# ./vmware-install.pl
-bash: ./vmware-install.pl: /usr/bin/perl: bad interpreter: No such file or directory.

I do a ls in the directory and it shows the installer in there.
[root@LinuxTest01 vmware-tools-distrib]# ls
bin doc etc FILES INSTALL installer lib vmware-install.pl


The only step I didnt do in this article is the prereq. first step because Yum is always trying to connect to the internet and my Centos 7 box is on a classified network with no internet access.

I want to connect a windows workstation to a rh linux network by a 35 meter network cable but it reads 10 Mbps speed and I can't virualize a physical redhat machine in the network
Is the problem with the windows, the cable length or I need to do some configuration in redhat.

I am making the commitment to a linux server and am excited about all of the possibilities. One thing I was hoping for is network monitoring. My internet is not very good (DSL) and if an attached device decides to download an update it makes Netflix sputter and collapse. The problem is I have to check each device manually to see if the network drain is on my end or if it’s the ISP crapping out. This can be time consuming and frustrating.

Is there a program that can easily tell me how much information is being uploaded and downloaded onto the WWW? I fear this is going to need a router upgrade and my router won’t run DD-WRT or Tomato.

Thank you in advance

I just installed RH 7.3 on my Dell Poweredge 1750. The install did not find or configure the existing Broadcom Netxtreme BCM5704 Gigabit network controllers. What can I do to resolve this problem?

Hi everyone, I am a new member and also new to linux, I encountered a problem, but last week I tried but did not solve
I downloaded iso file linux 1.1.0 on page potassium https://www.kali.org, I installed on my Dell inspiron n4010, it works very well and does not have any errors, but after I update and upgrade all packages, I rebooted the system switches to the command line, I lost a lot of time to return to the graphics, but when booting up the network manager icon not seen, I have set the package network-manager-gnome_0.9.4.1-0ubuntu2_i386.deb network manager icon show but when click on the network manager icon only contained text "network manager is not running."
I also installed Wicd but could not run "could not connect to wicd's D-Bus interface. Check the wicd log for error messages."
wireless driver apparently was set before
root@kali:~# airmon-ng
PHY Interface Driver Chipset

phy0 wlan0 wl Broadcom Corporation BCM4313 802.11b/g/n (rev 01)

please help me!
please guide installed offline, my kali linux no internet connection. can download package from another machine to install.

I have a number of CentOS 7 VMs and there is only one that won't automatically connect to the wired network.

Thru the gui (Gnome 3.8.4), I found the checkbox to automatically connect it, however I would like to know what file to modify in the future for my learning experience.

I was not able to find the file to modify. I looked under /etc/sysconfig/network-scripts.

thanks

I just installed Redhat 7 and try to config the network , add the IP address to network card , but I got the problem.

I modify the file /etc/sysconfig/network-scripts/ifcfg-enp0s3 , the configuration is as below , and then reboot .

DEVICE="enp0s3"
NETBOOT="yes"
HWADDR="08:00:27:15:38:B7"
TYPE="Ethernet"
BOOTPROTO="none"
NAME="enp0s3"
UUID="462f4834-4fe7-43a7-84e7-83b2722e94c1"
ONBOOT="yes"
IPADDR="192.168.1.1"
NETMASK="255.255.255.0"

After reboot , I use "ip addr show" still not shown the ip address , the ip address is still blank , would advise what is wrong ? thanks
