 |
|
For some reasons my gentoo is able to detect the ethernet card, but I can't ping to or connect to websites.
These are the config files that I have (i only configured this during installation):
| Code: | /etc/hostname
127.0.0.1 localhost
::1 ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
|
| Code: | /etc/conf.d/net
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"
|
and this is what i got for "ifconfig"
| Code: |
eth0 Link encap:Ethernet HWADDR: xx:xx:xx:xx:xx:xx
inet addr: 130.179.130.10 Bcast: 130.179.130.135 Mask: 255.255.248.0
UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU: 1500 Metric: 1
RX packets 25169 errors: 0 drop: 0 overruns: 0 frames: 0
TX packets 27 errors: 0 drop: 0 overruns: 0 carriers: 0
collision: 0 txqueuelen: 1000
RX bytes: 2115205 (2.0 Mb) TX bytes: 2770 (2.7 Kb)
Interrupt: 9 Base address: 0xa000
lo ....
|

greatly appreciate any suggests and comments.

here is the output for #route
| Code: |
Destination Gateway Genmask Flags Metric Ref Use Iface
192.178.0.0 * 255.255.255.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default 192.178.0.1 0.0.0.0 UG 0 0 0 eth0
|
#ping -c 3 www.google.com
unknown host
#ping -c 3 64.233.187.99
| Code: | 3 packets transmitted, 3 received, 0% loss, time 2000ms
rtt min/avg/max/dev = 87.308/96.526/109.366/9.368 ms |
and inside /etc/resolv.conf, there's nothing (it only has a comment about the lo) |

your default gateway should be unreachable:
default 192.178.0.1 0.0.0.0 UG 0 0 0 eth0
because your ip address is (based on ifconfig):
inet addr: 130.179.130.10 Bcast: 130.179.130.135 Mask: 255.255.248.0
but u could ping google.com (when using the ip), so apperantly ur problem is the resolv.conf:
ask ur admin for the dns server ip and when u know it:
echo "nameserver <ip-add>" >> /etc/resolv.conf
u can try with 81.210.131.2 and 81.210.131.3:
echo "nameserver 81.210.131.2" >> /etc/resolv.conf
echo "nameserver 81.210.131.3" >> /etc/resolv.conf |

You aren't letting dhcp set your nameserver settings automagically. It is not necessary to go through the trouble of manually setting your dhcp info if you are using dhcp. Just remove:
| Quote: | | dhcp_eth0="nodns nontp nonis" |
from /etc/conf.d/net.
Your nameservers will be set by your isp's or home dhcp server.
