Interface Detection Infiniband MAC wrong

[Maik Götte]

Machines with infiniband adapters are all listed with identical MAC-adresses which is obviously a problem of the 20 byte hardware address of those adapters in contrast to the standard 8 byte address.
Interface detection, as far as I can see, is done bei "ifconfig" which, btw is deprecated. ifconfig truncates the hardware address to 8 byte even if it's an infiniband interface:

> ifconfig -a

Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes.
Because Infiniband address has 20 bytes, only the first 8 bytes are displayed correctly.
Ifconfig is obsolete! For replacement check ip.

So I boldly suggest and humbly request rewriting the perl code for network interface detection using "ip". It looks like the database should be able to store the different sized MACs (varchar(255)) so it seems to "only" be the code

I'm actually working on a fix.

[Maik Götte (maik-goette)]

patched files:
perl/Ocsinventory/Agent/Backend/OS/Linux/Network/Networks.pm
perl/Ocsinventory/Agent/Backend/OS/Linux/Network/IPv4.pm

Changed route and ifconfig to ip (addr / route) and iwconfig to iw.

Infiniband MAC ist now correctly shown in the database.

Wifi-Adaptes were not tested but the code should work as before (setting Type to Wifi).

The old code is commented in the files so the changes mad should be comprehensible.
It would be great if the fix could make it into the 2.2 version.

Best regards
Maik

Hi,

launchpad is no more used. OCS inventory project has moved to github.

Please open an issue here => https://github.com/OCSInventory-NG/UnixAgent
