Hello,
My issue may be related. I have a laptop which I just upgraded to
openSUSE 11.4 (retail version0 from 11.3. I cannot change the MTU for eth0
(which is wired connected to a 10/100 Mb switch -- have not tried the WLAN
device yet) through the NM Manage Connections dialog. The value I enter is
written somewhere because it persists in the NM Manage Connections dialog. But
it is not written to "/etc/NetworkManager/system-connections/Auto eth0", and it
has no effect on the actual device's MTU. Manually adding "mtu=1492" to the
[802-3-ethernet] section in "/etc/NetworkManager/system-connections/Auto eth0"
does work. Some thoughts: are the device action policies correctly set (I
have not changed them); is somehow KWallet (where my WLAN credentials are
stored) interfering with the system authentication required to modify
"/etc/NetworkManager/system-connections/Auto eth0" (I am never prompted for the
root password). Anyway,...
Reproducible: Always
Steps to Reproduce:
1. install OpenSUSE 11.4 on a system with wired and wireless LAN
2. keep networkmanager as the default to control the network connections
3. use NM manage Connections to change the MYU from Automatic to 1492
4. Disable and reenable networking (using NM) to force a reconfiguration of
eth0
5. From a terminal, run /sbin/ifconfig eth0 and note the MTU setting
Actual Results:
The MTU is still 1500.
Expected Results:
The MTU to be 1492
