Verify interfaces and their status
ifconfig [Physical LAN]
iwconfig [Wireless LAN]
Previous versions (before BT5R3) had networking disabled by default.
To start it use:
/etc/init.d/networking start
or could use the command “start networking”
Enable SSH
sshd-generate
/etc/init.d/ssh start
could also have said “start ssh”
Assign static IP, and bring interface up
ifconfig eth0 192.168.1.222/24 up
ifconfig eth0
Configure default gw
route add default gw 192.168.1.1
ping 8.8.8.8
See the contents of the resolv.conf file
more /etc/resolv.conf
Add dns info to resolv file
echo nameserver 8.8.8.8 > /etc/resolv.conf
Ensure network config is permanent
vi /etc/network/interfaces
! use ins key to change edit mode
! edit the interface that is being used on your BT
iface eth0 inet static
address 192.168.1.222
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
! use esc : w q (to save and exit)
Another way of making the IP persistent accross reboots
update-rc.d networking defaults
enable ssh at boot time
update-rc.d -f ssh defaults
Enable/Disable/Restart networking service, if ever you need to
/etc/init.d/networking start
/etc/init.d/networking restart
/etc/init.d/networking stop
Options for up and down
ifconfig eth0 up
ifconfig eth0 down
to become dhcp client
dhclient eth0
useful commands
folder size; run from root / or any other directory you’re in to see largest folders
du -smh * | sort +0nr
also to see;
disk usage partitions and amount of spaced, used, available and total size use
dh -h (this is human readable i.e show it like 500Mb etc)
dh -k also
Package management commands in debian;
sudo apt-get update (updates to latest apt-get)
sudo apt-get install rpm (downloads and installs rpm)
sudo apt-get install alien (downloads and installs alien so you can convert .rpm files for red hat to .dpkg for debian)
sudo alien nmap-5.51-1.i386.rpm (this runs alien on the .rpm file convert it to .deb , debian format)
dpkg -i nmap-5.51-1.i386.deb (dpkg – debian package manager rpm = red hat package manager)
