I IPLed a system (version 20101020ubuntu416), started the installer, configured
a first network device with static IPv4 and connected via ssh to the installer.
I chose "expert mode" and selected "Configure the network device" instead of
continuing at "Choose language".
I selected my second OSA device and accepted this configuration.
Consequently I chose "Configure a network using static addressing" instead of
continuing at the proposed "Choose language".
And immediatedly this session wasn't reachable any more. A parallel ping to
this session did stall at the moment, when I pressed "Configure a network using
static addressing". Obviously this action dropped the default gateway - here
the result when entereing a shell to debug the situation:
~ #>ip a s
ip a s
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue
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
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enccw0.0.f5f0: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 02:a2:0f:00:00:99 brd ff:ff:ff:ff:ff:ff
inet 9.152.162.103/22 brd 9.152.163.255 scope global enccw0.0.f5f0
valid_lft forever preferred_lft forever
3: enccw0.0.b1c6: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
link/ether 02:00:00:5b:9f:69 brd ff:ff:ff:ff:ff:ff
~ #>ip r l
ip r l
~ #>
The network interfaces are both down, and thus all routes were lost!!
When I bring up the first interface manually
ip link set enccw0.0.f5f0 up
and add the route and the default gw:
ip route add 9.152.160.0/22 via 9.152.160.1
ip route add default via 9.152.160.1
I can continue with the IP configuration of the second network interface

I revived the first network interface as described above to get access to the
system and to collect the data.
