Some Useful Raspbian commands

Conventions used here

  • filename appname directory path are used only as placeholders. Substitute your specific case.

  • The path you enter can be absolute (from the top root level) or relative to current directory. Paths from root always start with /. Use ../ to move up the directory hierarchy.

  • *deprecated means it still works but this command will eventually disappear.

  • > is used to denote your terminal prompt. Don’t enter it!

  • Comments are in bracketed (normal) text. Don’t enter these either!

WiFi and Networks

Show WiFi networks > ifconfig wlan0 *deprecated
Show all network addresses > ip addr (ifconfig -a is *deprecated a=all)
Ethernet network commands – Substitute eth for wlan
WiFi turn on > sudo ifup wlan0 (0=1, 1=2, wlan1, wlan2 etc.)
WiFI turn off > sudo ifdown wlan0
WiFi forced on > sudo ifup --force wlan0
WiFi forced off > sudo ifdown --force wlan0

Show events from your WiFi > iwevent
WiFi network 1 details > sudo iw wlan0
Show high level wireless information > iw wlan0 info
Show information to troubleshoot the wireless > iw dev wlan0 link
Scan WiFi network 1 > sudo iw wlan0 scan
Scan local wireless networks > sudo iw dev wlan0 scan (much information!)
Scan only your internal network > sudo nmap -sP 192.168.0.0/24
(Note: also works in OS X; substitute your router’s IP format)
Create wireless passphrase > wpa_passphrase ssid passkey
(Note: must have wpasupplicant installed)

Services

Service status > service --status-all
Start SMB service > sudo service smbd start (Windows file sharing)
Stop SMB service > sudo service smbd stop
Restart SMB service > sudo service smbd restart


VNC commands

Install tightvncserver > sudo apt-get install tightvncserver
Start tightvncserver > sudo /etc/init.d/tightvncserver start
or tightvncserver
Stop tightvncserver > sudo /etc/init.d/tightvncserver stop
Open SSH connection > ssh pi@pi.IP.address (in your computer Terminal)


DHCP commands *

Where are DHCP leases? > /var/lib/dhcp/dhclient.leases
Get IP Address or Renew network lease > sudo dhclient wlan0/eth0
Remove all leases and renew > sudo rm /var/lib/dhcp/dhclient.leases; sudo dhclient wlan0/eth0
* Note: These commands are only for when the Pi is being used as a DHCP server.


Other useful commands

List loaded modules > sudo lsmod
Root file access > (first) alt F2 (then) gksudo nautilus
Get AP info > iwlist scan
Get wireless info > iwlist (many options shown!)
