Someone teach me basic networking for linux

[rebrov]

i just installed bt4 pre final and every thing is okay

im now trying to edit my mac address from terminal with

# ifconfig eth0 down
# ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx
# ifconfig eth0 up
# ifconfig eth0 |grep HWaddr

and its okay now for ip and netmask

ifconfig eth0 192.168.1.10 netmask 255.255.255.0 up

and its okay now for gateway

route add default gw 1.1.2.2 eth0


and last thing i edited resolv.conf with nano to add DNS

#nano /etc/resolv.conf

and i added 2 lines

DNS1 xxx.xxx.xxx.xxx
DNS2 xxx.xxx.xxx.xxx


and now for use browsing but first i tried to ping google with


ping google.com

or ping yaho.com

Your problem is somewhere in those four lines. See if you can figure out what it is.

ifconfig eth0 down
ifconfig hw ether xx:xx:xx:xx:xx:xx
ifconfig up
dhclient eth0

why do you need a static ip? if you really really need that static ip

nano /etc/network/interfaces

auto eth0
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1

/etc/init.d/networking restart

and check the output of router make sure there is no 1.1.2.2 because im pretty sure your router doesnt broadcast that address

[streaker69]

once i typed : nano /etc/network/interfaces i got this :

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth0 inet dhcp

auto eth2
iface eth0 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0






thats it and i typed under : auto eth0 what u told me to type


so it become ::::::

auto eth0
iface eth0 inet static
address 10.0.0.167
netmask 255.255.255.0
gateway 10.0.0.1

and the rest in /etc/network/interfaces is the same or should i delete some things from it ??


and another Question be4 like i did up when i restart pc every thing return again to default no ip or gw or mac like i sat :S:S why ?

No offense, but if you don't even know these incredibly basic functions, you probably no no business using backtrack.

sorry for the title :S i just read the rules and wont happen again

but anyone tell me whats wrong with my commands for networking !!?

i didn't figure out yet why i can't use internet i added ip , mac , dns , subnet

but still got nothing :S

ifconfig eth0 down
ifconfig hw ether xx:xx:xx:xx:xx:xx
ifconfig up
dhclient eth0

why do you need a static ip? if you really really need that static ip

nano /etc/network/interfaces

auto eth0
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1

/etc/init.d/networking restart

Repeat after me " I will use the edit button instead of making multiple consecutive posts." lather, rinse, repeat.

You have two options:

1) Get several books on basic networking. READ them. Rinse, repeat until you know how networking works.

2) Start with a distro that is more user friendly, and join a forum for Linux beginners.

Back|track is designed for advanced users who are doing infosec. You, quite obviously, fit neither of those criteria.

1st of all i did like every body said in google about how to set ur ip and gateway and the rest of networking basics things and nothing happened and

every reboot the mac changes when i type : ifconfig eth0

i see the mac changes and no ip and no gateway like i typed

thats maybe something bug with backtrack 4 pre thats why i came here to ask cuz this place is what its come from and i want to learn info sec so i installed backtrack i dont have much time to install simple linux distro and learn networking and then after long time install backtrack to learn infosec again


i want to do 2 x 1 i hope u guys understood me and instead of saying so trying to give a help not every one saying so make me feel like im under zero and u guys pro in ethical hackers and pentersters
