How to fix those error messages ?

Thanks.

Looks like maybe a network setup error on the host
What does:

ip a

report?

Hi Tommylight, I followed your tutorial to set up my 7i92 except that i use WICD to be able to swap easily between ethernet and my usb wifi dongle.

I use WICD because i was not able to set up Network Manager to be able to swap easily between the two networks. There are some posts on the forum of people using WICD with success.

Here you go :

Right, so you have not disabled IPV6 on the Ethernet interface
You should do this either in the interfaces file or by using network manager

Thanks PCW, I am a noob in network configuration.

Now I understand the meaning of "IPV4 routes to be selected" in TommyLight tutorial, that was not proposed upfront in WICD.

I chose to modify my pre-connect script in WICD to include what is necessary to disable ipv6 according to what i found on the web :

Code:
#!/bin/sh sysctl -w net.ipv6.conf.all.disable_ipv6=1 sysctl -w net.ipv6.conf.default.disable_ipv6=1 sudo ethtool -C eth0 rx-usecs 0

And now the "ip a" command does not show "inet6..." anymore :

Code:
lathe@debian:~$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:24:81:99:9a:72 brd ff:ff:ff:ff:ff:ff inet 10.10.10.5/24 brd 10.10.10.255 scope global eth0 valid_lft forever preferred_lft forever 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 74:da:38:6f:42:9f brd ff:ff:ff:ff:ff:ff lathe@debian:~$

Code:
inet 10.10.10.5/24 brd 10.10.10.255 scope global eth0
That should be 10.10.10.5/8, not 24, although it should work as is. What is your gateway and dns set to ? They must be set at 10.10.10.1 for it to work.

Here you go : Snapshot of the WICD configuration panel related to the ethernet connection.

I just figured out that I did not define a DNS server. It looks like it is working fine without. Is it really necessary ?

Not really, it does work without it, but sometimes takes longer to find an address.
Also the netmask should be 255.0.0.0 for 10.n.n.n addresses, but it will work as is, no worries.
