SVN 3080: NIC Registration
-
[quote=“Tom Elliott, post: 43618, member: 7271”]Oh, i do have a thought though.
Using the generate our interfaces file on the fly method, I can add the e-polling capabilities of the kernel to use more proper methods of device management. This means not all devices will automatically have eth* names, but rather whatever the device is. Is there a simpler way without designating the specific devices to search for?[/quote]
[CODE]# Set for loop delimiters to just newline
IFS=$‘\n’Create a pipe-separated MAC list
for macline in $(ip addr | grep link/ether)
do
# Add a pipe before adding more MACs
if [ -n “$mac” ]; then
mac=$mac|
fi
mac=$macecho $macline | xargs | cut -d ' ' -f 2
doneReset delimiters
IFS=[/CODE]
I just realized I was doing a grep on link/ether so that doesn’t include lo. Enjoy!

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

[code]# 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
}[/code]Caught a bug with your final mac= statement. Also, “ip addr” is fine by itself.
-
yeah I saw and edited. The echo needs to occur there. and I am using just ip addr

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

I don’t think so…
[CODE]# Get All Active MAC Addresses
getMACAddresses()
{
IFS=$‘\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
}[/CODE]
No ip, no awk, no grep… -
And I still wonder, why do we need the IFS here??

No ip, no awk, no grep…[/quote]It grabs lo’s MAC. But I like where this is going…
-
[CODE]… cat /sys/class/net/???*/address …[/CODE] kind of hackish but…
-
How low can we go?
[CODE]# 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
}[/CODE] -
sed, grep, tr and all the rest are very nice but we don’t really need them here, do we?
[CODE]… cat /sys/class/net/[^l][^o]*/address …[/CODE]And still wondering about if ‘IFS’ is needed here. Sorry goto go now.
-
I like it

Uncle Frank, cspence’s means no loops either!

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

[quote=“Uncle Frank, post: 43632, member: 28116”]
[CODE]… cat /sys/class/net/[^l][^o]*/address …[/CODE]
[/quote]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 -
lol
it means to cat all directories EXCEPT those with l, then o (or in this case lo) -

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…
[CODE]# Get All Active MAC Addresses
getMACAddresses()
{
macs=$(cat /sys/class/net/[^l][^o]*/address | tr ‘\n’ ‘|’)
echo -n ${macs%$‘|’}
}[/CODE]
Just make sure we use BASH (not SH) because the terrorist style (lol) shell glob does not work with SH… -

Very usefull, I’ll use in my script !
-
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.
-
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.
