How to set up a bridge with "bridge_ports none" on Debian Stretch in /etc/network/interfaces?
Setting the default gateway to your own IP address doesn't make much sense thus isn't accepted:
$ sudo ifup -v br0 ifup: configuring interface br0=br0 (inet) /bin/run-parts --exit-on-error --verbose /etc/network/if-pre-up.d run-parts: executing /etc/network/if-pre-up.d/bridge Waiting for br0 to get ready (MAXWAIT is 32 seconds). run-parts: executing /etc/network/if-pre-up.d/vde2 run-parts: executing /etc/network/if-pre-up.d/wpasupplicant /bin/ip addr add 10.0.10.1/255.255.255.0 broadcast 10.0.10.254 dev br0 label br0 /bin/ip link set dev br0 up /bin/ip route add default via 10.0.10.1 dev br0 onlink RTNETLINK answers: Invalid argument ifup: failed to bring up br0
Your broadcast setting is suspicious as well, the customary value would be 10.0.10.255, which you wouldn't even need to specify. Just use modern syntax:
iface br0 inet static address 10.0.10.1/24 bridge_ports none

I have name/value pairs I want to pipe as objects to an Advanced Function.
I'm starting with an OrderedDictionary that looks like this:
$jobs = [ordered]@{0='job0';1='job1';2='job2';3='job3';4='job4'; 5='job5';6='job6';}
Console output looks like this:
$jobs Name Value ---- ----- 0 job0 1 job1 2 job2 3 job3 4 job4 5 job5 6 job6
The function looks like this:
Function Process-Jobs { [cmdletbinding()] Param ( [Parameter(ValueFromPipeline=$true)][hashtable]$jobs ) Begin { Write-Output '--> begin block <--' } Process { Write-Output $_.Name Write-Output $_.Value } End { Write-Output '--> end block <--' } } $jobs = [ordered]@{0='job0';1='job1';2='job2';3='job3';4='job4'; 5='job5';6='job6';} $jobs | Process-Jobs
The above code does not work and returns this to the console:
--> begin block <-- --> end block <--
I tried making the hash table a custom object like this:
$jobs = [PSCustomObject][ordered]@{0='job0';1='job1';2='job2';3='job3';4='job4'; 5='job5';6='job6';}
Console output looks like this:
$jobs 0 : job0 1 : job1 2 : job2 3 : job3 4 : job4 5 : job5 6 : job6
If I modify the function...
Function Process-Jobs { [cmdletbinding()] Param ( [Parameter(ValueFromPipeline=$true)][PSCustomObject]$jobs ) Begin { Write-Output '--> begin block <--' } Process { $i = 0 Write-Output $jobs.Name Write-Output $jobs.$i } End { Write-Output '--> end block <--' } } $jobs = [PSCustomObject][ordered]@{0='job0';1='job1';2='job2';3='job3';4='job4'; 5='job5';6='job6';} $jobs | Process-Jobs
Console output looks like this:
--> begin block <-- job0 --> end block <--
It seems I've lost the ability to reference the Name property.
How do I access the Name property of the
$jobs
object?I start with the OrderedDictionary because I need it for processing elsewhere in the function.
Is there a better way to pipe name/value pairs to an Advanced Function?
Should I use something like this:
$jobs = New-Object –TypeName PSCustomObject $jobs | Add-Member –MemberType NoteProperty –Name 'Name' –Value 0 $jobs | Add-Member –MemberType NoteProperty –Name 'Value' –Value 'job0' ... $jobs | Process-Jobs
will need additional code to loop and sort...
