I used perl::Net:IPv4Addr in order to be able to parse /usr/bin/ip (as ifconfig
output is not reliable anymore).
The output of the ip command uses cidr netmasks and I need to convert cidr
netmask to std netmasks. (example: parse 10.8.64.23/22 and get 10.8.64.23 and
255.255.252.0)
The module is available on rhel6 (epel repo), fedora at least 17+, ubuntu 12.04+
deb package: libnetwork-ipv4addr-perl
rpm package: perl-Net-IPv4Addr
Regards,
PS: I've seen that perl-Net-IP is also available on all platforms, but I ccan't
tell if there is a function that also permit to parse cidr netmasks.(this
module seems far more complete, but right now I can't tell if it's usefull to
me). We can change that later if relevant.

Objet : Re: [Oscar-devel] set_node_nics now uses ip instead of ifconfig.
Hi Olivier,
Is perl::Net::IPv4Addr module a build-in one in most distros? It seems that it
is not available in my MacBookPro. Yes, we can install the package containing
the perl module.
ftp://rpmfind.net/linux/epel/6/x86_64/perl-Net-IPv4Addr-0.10-6.el6.noarch.rpm
So, does this perl module do some better job than using "ifconfig" or "ip"?
Is this for getting a mac address or such?
Regards,

Hi,
I've hopefully fixed set_node_nics ifconfig parsing problem by replacing
ifconfig with ip and I'm parsing "ip addr" output.
hopefully it's ok.
I'm using perl::Net::IPv4Addr and updated spec and debian/control to have this
requirement.
I've noticed that none of spec or debian/control file has dependancies on third
party commands like ifconfig and such.
I known that there are prerequisites, but they are installed later. more over
it's not clean. For example, oscar-config will fail if no ifconfig command is
found (now /usr/bin/ip).
I think we should crosscheck this......(IMHO).

Olivier.
