Last modified: 2012-10-21 05:18:45 EDT
Description of problem: Network manager has got OLPC for GNOME 3. When I upgrade my OLPC version from 11.* to 12.1.0 I was connected on some Wi-fi and all OK. However, after upgrade software from yum. I am connected on Wi-Fi but, I have not got an Internet connection. Version-Release number of selected component (if applicable): F17 - OLPC XO-1.75 Network Manager version: 0.9.4.0-9.git2 @koji.dist... Uname -a: Linux xo-74-33-76.localdomain 3.0.19_xo1.75-20120803.1234.olpc.f49cd50 #1 PREEMPT Fri Aug 3 12:44:10 EDT 2012 armv7l armv7l armv7l GNU/Linux Steps to Reproduce: 1. Clic on connection icons (I guess NM-applet) 2. Select wifi network to connect. 3. Connect it. Open browser Additional info: How to solve? You need run # dhclient eth0 to get IP address and surf on the net.
"Additional info: How to solve? You need run # dhclient eth0 to get IP address and surf on the net." P.S: Always that you change Wi-Fi net, you need run these command.
Would you run these command in a terminal after you connected to the Wi-Fi and attach their output here (but before running dhclient): $ nmcli dev $ nmcli con s $ ip a $ ip route $ cat /etc/resolv.conf Also, /var/log/messages file with NetworkManager logs would be helpful.
Yup! $ nmcli dev DEVICE TYPE STATUS eth0 802-11-wireless connected $ nmcli con s NAME UUID DEVICES PREDETERMINED VPN MASTER-PATH wlan0 0cac..... eth0 yes no not established $ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 20:7c:8f:74:33:76 brd ff:ff:ff:ff:ff:ff inet 192.168.1.35/24 brd 192.168.1.255 scope global eth0 inet6 fe80::227c:8fff:fe74:3376/64 scope link valid_lft forever preferred_lft forever $ ip route default via 192.168.1.1 dev eth0 proto static 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.35 $ cat /etc/resolv.conf All is commented

So you have an IP address, you just don't have DNS. Hm... Oct 17 13:55:51 xo-74-33-76 NetworkManager[378]: <warn> could not commit DNS changes: (0) Could not replace /etc/resolv.conf: Device or resource busy though this does not seem to be the same as bug 867432, since /var/log/messages seems to show that selinux is disabled.
http://dev.laptop.org/ticket/12121 suggests that this is in some way caused by using yum to update OLPC packages, which is apparently not supported.
Yes, but I do not understand why maintain packages with yum. :/ . So, if a software is vulnerable, how to patch it without upates? However, with 11.* version, you can upgrade your packages in your system and nothing occurs this. SElinux is disabled by default.
