[Bug 297329] Re: Presence server crashes if no interface is configure

[mungewell]

Checked and still crashes. It seems to do it when the default interface
is up but not connected.

Method: remove ethernet cable and 'sudo /etc/init.d/networking restart', watch the dhclient timeout.

It does not crash (testing after each command) if I do:
1) 'sudo ifdown eth0'
2) 'sudo ifconfig eth0 up' with no parameters
3) 'sudo ifconfig eth0 up 192.168.1.123 netmask 255.255.255.0'
4) 'sudo route add -net default gw 192.168.1.123'

I did try 'sudo route add -net default gw 0.0.0.0', but apparently this
is illegal.

After the crash presence server is not running.

You received this bug notification because you are a member of Sugar
Team, which is subscribed to sugar in ubuntu.

Status in “sugar” source package in Ubuntu: New

Bug description:
Binary package hint: sugar

It looks like Sugar (and Sugar-Emulator) will fail to start if there is not an ethx(??) interface configured.

Doing 'sudo ifconfig eth0 192.168.1.20 netmask 255.255.255.0' allow the boot to continue and start Sugar interface.
