 Posted: Thu May 10, 2007 10:38 pm Post subject: [SOLVED] Direct Cable Connect RT8111B |
 |
|
I have been trying for a long time to connect my 2 PCs together using a crossover ethernet cable - yes you guessed right - I can't do it 
Each PC is connected to a network switch/ hub (ethernet) which is connected to the internet. I want to create a (secure) direct link between the two but I cant seem to get the NIC (Eth1) to become active on my Gentoo box.
Here is ifconfig:
| Code: |
eth0 Link encap:Ethernet HWaddr 00:18:4D:E9:88:ED
inet addr:10.0.0.7 Bcast:255.255.255.255 Mask:255.255.255.0

So ite seems to me to be configured correctly - maybe?
Here is conf.d/net
| Code: | iface_ra0="dhcp"
preferred_aps=( "Gentoo_Home" )
associate_order="forcepreferredonly"
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"
config_eth1=( "dhcp" )
dhcp_eth1="nodns nontp nonis" |
Both eth 1 & 0 are included in rc (default) and they have both been symlinked to init.d as per the Gentoo Handbook.
I have tried connecting with the windows firewall turned off and still nothing.
I have no firewall installed on Gentoo as yet (why not advertise it )
I can connect to the internet no problem via eth0 - it seems to work fine.
Eth1 is a RT8111B the drivers installed as per the following script found on the Ubuntu forum
| Code: |
wget ftp://202.65.194.211/cn/nic/r1000_v1.05.tgz
tar xzvf r1000_v1.05.tgz
cd r1000_v1.05
make clean modules
make install
depmod -a
modprobe r1000
|
lsmod gives me the following
| Code: |
lsmod
Module Size Used by
r1000 18572 0
ath_pci 84256 0
wlan 171588 1 ath_pci
ath_hal 193616 1 ath_pci
nvidia 6829940 32
rt61 219268 1
|
It seems to me that the r1000 module is inactive?
lspci gives me the following
| Code: |
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Unknown device 8168 (rev 01)
01:02.0 Network controller: RaLink RT2561/RT61 rev B 802.11g
01:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139 C+ (rev 10)
|
I dont have a clue as to what to do next?
I am using the gentoo-sources 2.6.21 kernel with the 2.6.21 linux-headers - I thought support was built in for my NIC but I cant find it.
If you could help me you will have made me one very happy person as I am totally stumped 
TIA

Unless you have a dhcp server running on your windows box, you will want to give your "internal" network static ip addresses.
To do this, remove/comment out
/etc/conf.d/net
| Code: |
#config_eth1=( "dhcp" ) to....
config_eth1=( "192.168.0.1/24" )
|
Then restart that ethernet port...
| Code: |
/etc/init.d/net.eth1 restart
|
Also..
Generally, most 1000mbit cards can automagically swap the send a recieve pins so a cross-over cable is unnecessary.
On the windows box, you will want to setup the computer with a static ip address too,
It should look like this in TCP/IP properties...
192.168.0.2
255.255.255.0
With that setup you should be able to ping each computer.

Godfish you are a star - thank you very much it works a treat - the connection is up 
One question remaining - how can I force the connection to windows to use Eth1 as it seems to prefer Eth0?
I have just transferred my music across but it has gone via the network hub - this was not what I had planned.
Any further help would be appreciated even more 
TIA (again) |

Just unplug the cable from eth0, then all the data will flow through eth1. 
Even though this is not the solution you are looking for, you may want to try it anyways just to make sure eth1 works at all. |

Why is it that the most simple solution is the last that comes to mind?
Well I unplugged eth0 and smb tells me that
| Code: | | Unable to find any workgroups in your local network. This might be caused by an enabled firewall. |
So I disabled my firewall and the windows firewall is not running either. I still get the warning from smb.
ifconfig gives the following - it seems not to have an IP address?
| Code: | eth1 Link encap:Ethernet HWaddr 00:19:66:0B:5F:AC
inet6 addr: fe80::219:66ff:fe0b:5fac/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:569 errors:0 dropped:0 overruns:0 frame:0
TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:78028 (76.1 Kb) TX bytes:2520 (2.4 Kb)
Interrupt:18 Base address:0x2000
|
However windows is claiming that it is connected?
| Code: | iface_ra0="dhcp"
preferred_aps=( "Gentoo_Home" )
associate_order="forcepreferredonly"
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"
config_eth1=( "192.168.0.1" )
dhcp_eth1="nodns nontp nonis" |
I'm at a loss still |

I would take out the line | Quote: | | dhcp_eth1="nodns nontp nonis" |
as you are no longer using dhcp on that interface. You definitely want ifconfig to report an ip address of 192.168.0.1 else it will not work.
On your linux computer, make sure u can ping 192.168.0.2...
Also, if you only want smb to function on one interface, modify /etc/samba/smb.conf to include
| Code: | [global]
bind interfaces only = yes
interfaces = eth1 |
Windows saying it is connected only means that there is a physical connection... you need more then just layer one connectivity

Thanks godfish
My smb.conf already has your recommendation.
I have modified my conf.d/net as per the Gentoo Handbook - it reads
| Code: | iface_ra0="dhcp"
preferred_aps=( "Gentoo_Home" )
associate_order="forcepreferredonly"
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"
#config_eth1=( "192.168.0.1" )
#dhcp_eth1="nodns nontp nonis"
config_eth1=( "192.168.10.101 netmask 255.255.255.0 brd 192.168.0.255" )
routes_eth1=( "default via 192.168.10.1" ) |
I was still getting the firewall blocking access notification.
After re-installing my firewall - the problem has gone.
Thanks to all for your help - I would have still been fiddling otherwise. |
