More complex than I thought....
Broadcast and netmask are swapped....Parsing the output is not cool.
What about using /sbin/ip instead?
The only issue is that we need a function to transform /24 netmask to
255.255.255.0 (or /22 into 255.255.252.0) for example.
/sbin/ip is available on rhel6, fedora17+ ubuntu1204+ at least.
Perl-IPv4Addr is also available on all supported OSes, thus the above issue is
not one.
I give a try....

Objet : [PROVENANCE INTERNET] [Oscar-devel] newer ifconfig output changed =>
big impact.
Hi,
I've just discovered that newer ifconfig command output is different from older
versions.
now, "HWaddr" is replaced by "ether" and is not in the 1st line output now.
Old output:(rhel6)
eth0 Link encap:Ethernet HWaddr 00:0C:29:03:F3:77
inet addr:192.168.25.137 Bcast:192.168.25.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe03:f377/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:85972 errors:0 dropped:0 overruns:0 frame:0
TX packets:559096 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:114296781 (109.0 MiB) TX bytes:33830845 (32.2 MiB)
Interrupt:19 Base address:0x2000
New output:(fedora18 (and 17))
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.25.134 netmask 255.255.255.0 broadcast 192.168.25.255
inet6 fe80::20c:29ff:fefe:35b prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:fe:03:5b txqueuelen 1000 (Ethernet)
RX packets 811094 bytes 1185414193 (1.1 GiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 157789 bytes 10412250 (9.9 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
both are output from: LC_ALL=C /sbin/ifconfig
Thus OSCAR is impacted at many places: example: /usr/bin/set_node_nics in
find_nics() line 749 fails to find a nic...
Thus oscar-config --bootstrap fails with:
ERROR: Impossible to detect attached networks at /usr/bin/set_node_nics line
239.
I can't understand why I didn't noticed this before...
We are not alone on this point:

The new naming scheme:
http://docs.fedoraproject.org/en-US/Fedora/16/html/System_Administrators_Guide/appe-Consistent_Network_Device_Naming.html
Affected files: (seeking HWaddr)
oscar/lib/OSCAR/MAC.pm
oscar/scripts/set_node_nics
oscar/scripts/update_live_macs
pkgsrc/libv3m-v2m/trunk/qemu.cpp
pkgsrc/oscar_udev/trunk/lib/udev.pm
I'm currently working on set_node_nics.
Best regards,
Olivier.
