 |
|
Hi,
I have installed Gentoo on one of my boxes at home and whenever I turn it on the rest of the network (which are Windows machines) lose internet connectivity. They can all ping each other but nobody can get to the internet. Then when I shut down my machine everything goes back to normal... What couuld be happening?? |

Could you post your network configuration on Gentoo? Are you sure, that IP's are correctly assigned? As well as gateway, etc.?

Also, what is your network layout?
Do you have a hub, switch, router, broadband modem?
Is the network wired or WiFi?

I have wired/wireless router at IP 192.168.2.1 that services most of the house besides me. That router is connected to my cable modem.
Personally, I have one connection coming to my room where I have a hub that I plug in 2 or 3 machines.
There are a few machines that use DHCP and others are statically assigned, again these are ALL Windows machines.
Some are connected wirelessly and others via the wired connection.
Now, with all that being said, everything works great and we have never had problems before having that Gentoo box on the LAN. So I guess I am assuming it is sending out messages to everyone either taking over one of the important roles of the router, such as dns server or nameserver or something like that...
The settings for the static machines on the network are something like this:
| Quote: |
IP: 192.168.2.100
Default Gateway: 192.168.2.1
Subnet mask: 255.255.255.0
Preferred DNS: 192.168.2.1
|
All the machines in the house are NOT in a domain and are just in a commonly named WORKGROUP so they can all see each other.
Now the Gentoo machine has a domainname that is being set, is that going to be a problem?
This problem all started when I successfully installed Gentoo on the box in question and couldn't ping the outside world from it. I then tried messing with my resolv.conf file since the machine wasn't experiencing network problems internally since I could ping all the other machines on the network no problem... But I started messing with resolv.conf and then everyone in the house lost connectiivity and i had not even touched the router or anything. And then I turned of the server and like magic everyone was back online...
I will post the contents of resolv.conf and net.eth0 in my next post... |

ok I am going to save you guys wasted time by telling you exactly what happened...
I was going to send you the contents of /etc/conf.d/net and I realized I had my settings wrong and had 192.168.2.1 as my IP address which is my router, so the machines on the network were being confused by the fact and not getting to the outside world... How silly of me. |
