SVN 3080: NIC Registration

[cspence]

Registration registers eth0 regardless of connection state.

Version: SVN 3080
Server OS: Debian
NIC Not Used: eth0
NIC Used: eth1

PXE works fine on eth1 for me. Once the quick registration option is selected, it registers eth0 and carries on. Of course, it won’t recognize the machine on boot for imaging tasks until the MAC address is manually changed. Upon changing the MAC address to the eth1 adapter, the imaging process works fine.

This may be related to the other bug I reported earlier regarding multiple NIC hosts having trouble with any tasks.

inventory.php doesn’t do the registering, only auto.register.php handles this. 3102 should work, but I don’t have multiple macs to test against either.

Still figuring out where everything is going.

I was looking at fog.register, not fog.auto.reg. That would make sense! I’ll see if I can figure out what it is doing for you.

I just gave SVN 3102 a shot. The new code does what it should, but only the first MAC is registered (no additional MACs are registered). I lucked out and had it register eth1 instead of eth0. That’s good for me, but maybe not for someone else.

I don’t fully understand the inventory.php execution yet, but it must be only grabbing the first MAC and discards the rest.

sed, grep, tr and all the rest are very nice but we don’t really need them here, do we?

And still wondering about if 'IFS' is needed here. Sorry goto go now.
 
 
Very usefull, I'll use in my script !

Ohhhhh yes, now I see! Shouldn’t work till very late as I seem to overlook things too often then…

I’d vote for bash string manipulation…

# Get All Active MAC Addresses
getMACAddresses()
{
    macs=$(cat /sys/class/net/[^l][^o]*/address | tr '\n' '|')
    echo -n ${macs%$'|'}
}

Just make sure we use BASH (not SH) because the terrorist style (lol) shell glob does not work with SH…

[Tom Elliott]

lol
it means to cat all directories EXCEPT those with l, then o (or in this case lo)

What does that even mean?
I know DOS and VB, some Oracle... That stuff is so foreign I feel like it's terrorist related lol

Moments like these are why I love collaborating with others on code. Just a few suggestions and the code collapses to nothing.

I like it

... cat /sys/class/net/[^l][^o]*/address ...

And still wondering about if ‘IFS’ is needed here. Sorry goto go now.

[cspence]

How low can we go?

# Get All Active MAC Addresses
getMACAddresses()
{
    lomac=00:00:00:00:00:00
    cat /sys/class/net/*/address | grep -v $lomac | tr '\n' '|' | sed s/.$//g
}

[Sebastian Roth]

... cat /sys/class/net/???*/address ..
``` kind of hackish but...

I don’t think so…

># Get All Active MAC Addresses
getMACAddresses()
{
    IFS=
 
It grabs lo's MAC. But I like where this is going...\n'
    # Create a pipe-separated MAC List
    for macline in $(cat /sys/class/net/*/address); do
        # Add a pipe before adding more MACs
        if [ -n "$mac" ]; then
            mac=$mac\|
        fi
        mac=${mac}${macline};
    done
    IFS=
    echo $mac
}

No ip, no awk, no grep...

[Sebastian Roth]

And I still wonder, why do we need the IFS here??

We have to know the exact path name, so it’s simpler to just use the tools that get that for us I think.

# Get All Active MAC Addresses

Not using any extra ip tools … /sys/class/net/*/address …

[Tom Elliott]

yeah I saw and edited. The echo needs to occur there. and I am using just ip addr

[cspence]

# Get All Active MAC Addresses
getMACAddresses()
{
    IFS=$'\n'
    # Create a pipe-separated MAC List
    for macline in $(ip addr | grep link/ether | awk '{print $2}'); do
        # Add a pipe before adding more MACs
        if [ -n "$mac" ]; then
            mac=$mac\|
        fi
        mac=${mac}${macline};
    done
    IFS=
    echo $mac
}

Caught a bug with your final mac= statement. Also, “ip addr” is fine by itself.
