netdiscovery failing to do arp discovery on Redhat/Centos 7

[acdmail]

hi,
On try to run the network discovery task(agent version is 2.4.2) on Centos 7 I am getting below:
[root@localhost bin]# ./fusioninventory-netdiscovery --first 192.168.1.1 --last 192.168.1.2 --debug --control
[info] Can't run arp command, arp table detection can't be used

In fact it is normal as arp command is not shipped as default on Redhat/CentOs 7 anymore, iproute is used instead so on Centros/Redhat 7+: "ip neighbor show" should be used instead
Could you advise please?
Thanks

Hi @acdmail
on my CentOS 7 VM, I see arp command is provided by net-tools package.
Is that package installed on your system ? In which version ?

Updating the discovery also using ip show neighbor show as an alternative could be interesting to find the mac address for local machines.

hi @g-bougard,
I am using Centos 7.3.1611, minimal install, by default net-tools package is not installed on minimal install and all the network management tasks in OS are done using ip utility (part of iproute package).
For sure I can install net-tools package but this may be an issue to do in case of multiple machines to be inventoried

As I can see same seems to be true for Ubuntu minimal install, no net-tools by default (see it here please https://lists.ubuntu.com/archives/ubuntu-devel/2017-January/039651.html)

Thanks
