Cannot connect to internet in Fedora 19

Question

I am brand new to linux and am unable to connect to the internet in Fedora 19. When I type ifconfig I get:

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 150  bytes 12792 (12.4 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 150  bytes 12792 (12.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

p9p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::96de:80ff:fe2d:8274  prefixlen 64  scopeid 0x20<link>
        ether 94:de:80:2d:82:74  txqueuelen 1000  (Ethernet)
        RX packets 85  bytes 11964 (11.6 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 94 overruns 0  carrier 0  collisions 0

Also when I type netstat I get:

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State      
Active UNIX domain sockets (w/o servers)

I have tried to find what I can do to connect to the internet and I have been unsuccessful. I am using a wired connection through a router. I can ping 127.0.0.1 but cannot ping out.

Edit 1

When I open /etc/sysconfig/network-scripts ifcfg-profile_1-1 I get this

TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME="Profile 1"
UUID=d5d3e20c-6ef1-4e11-bf40-0cf5a7c6b463
ONBOOT=yes

Since PEERRDNS=yes what server information am I putting in the /etc/resolve.conf since mine is blank? Also in my network-scripts file I have ifcfg-lo and ifcfg-profile_1 and ifcfg-profile_1-1

Edit 2

When I type sudo dhclient p9p1 -v I get dhclient (2039) is already running -and exiting. this version of USC dhcp is based on the release available on FTP.isc.org. features have been added and other changes have been made to the base software release in order to make it work better with this distribution.

Answer 1

Seems you are getting no valid IP. Try the following: DHCP Client

To configure a DHCP client manually, modify the /etc/sysconfig/network file to enable networking and the configuration file for each network device in the /etc/sysconfig/network-scripts directory. In this directory, each device should have a configuration file named ifcfg-eth0, where eth0 is the network device name. The /etc/sysconfig/network-scripts/ifcfg-eth0 file should contain the following lines:

DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes

A configuration file is needed for each device to be configured to use DHCP. Other options for the network script includes:

DHCP_HOSTNAME — Only use this option if the DHCP server requires the client to specify a hostname before receiving an IP address. (The DHCP server daemon in Fedora does not support this feature.)
PEERDNS=<answer> , where <answer> is one of the following:
    yes — Modify /etc/resolv.conf with information from the server. If using DHCP, then yes is the default.
    no — Do not modify /etc/resolv.conf. 

The reason you can ping 127.0.0.1 it because it is the loopback interface the interface inside your pc.

Answer 2

Did you tried to use dhclient?

$ sudo dhclient -v

Answer 3

The easiest way would be to use dhclient:

$ sudo dhclient p9p1 -v

If you don't have a DHCP server on your network and you know the IP of you router, you can try to set a static IP:

$ sudo ip addr add 192.168.X.Y/24 dev p9p1
$ sudo ip route add default via 192.168.X.Z
