PoweringupRpi
1. Logintoyourrouterconsoleandlookatthelistofdevices
2. Sometimes,theraspberrypidoesnotpresentahostnameandbecomesachallengetoidentifytheIP!
3. Fortunately,weknowthattheRpiMACaddprefixis:B8:27:EB
OnceyouhaveretrievedtheIPAddress,wearegoodtogo!
Licensedunder:Attribution-ShareAlike4.0International(CCBY-SA4.0)
CheckIPAddressofRpi
LaunchyourfavouriteTerminalprogram(eg.Putty)andloginwiththefollowingdetails:
IPAddress:fromyourrouterPort(SSH):22username:pipassword:raspberry
Licensedunder:Attribution-ShareAlike4.0International(CCBY-SA4.0)
LoginviaSSH
1.)Enterthecommand:passwd
Youshouldsee:
Changingpasswordforpi.
(current)UNIXpassword:
EnternewUNIXpassword:
RetypenewUNIXpassword:
passwd:passwordupdatedsuccessfully
2.)Nextup,wewillmodifyassignastaticIPaddress.
Enterthecommand:ifconfig
Wewillneedtonotedownthefollowing:

inetaddr–192.168.1.100(currentIPAddress)Bcast–192.168.1.255(broadcastIPRange)Mask–255.255.255.0(subnetMaskAddress)
3.)Now,wewillgrabtheGatewayinfowithnetstat-nr
