vnet jail + VM problem with network

[laster13]

I created a vnet jail and I try to run at the same time a VM with VirtualBox but the network no longer works. I have tried to create a new interface with Bridge2 or epair5a and assign it to the VM but it does not work.

[alexey123]

When you start vnet jail, you organize network as bridge
As for my prestart script

Code: Select all

#!/bin/sh
#
sysctl net.inet.ip.forwarding=1 >/dev/null
bridge=`ifconfig | grep -m 1 bridge | cut -f 1 -d :`
if [ -z ${bridge} ]; then
	bridge="bridge20"
	ifconfig ${bridge} create > /dev/null 2> /dev/null
	ifconfig ${bridge} addm msk0
	ifconfig ${bridge} inet 10.0.0.100/24
	ifconfig ${bridge} up
fi
ifconfig epair4 create up
ifconfig ${bridge} addm epair4a

When jail stop, TheBrig destroy bridge. I find bug here and it will repair.

Vbox also tried open bridge, but 2 bridge with one member interface not work - you need add another interface to existens jail.
If you have idea, how to make it work - post here , and I'll upgrade TheBrig

Repaired.
You can simple update thebrig from web gui
Go to Extensions|TheBrig|Manager and press on update button

Thanks, Alexey. I just updated my installation. But I am already completely lost understanding about TheBrig versions. And I am afraid, not me only

Do you think it is possible to change minor version number each time then you change something? Ie 0.91.15, 0.91.16... Or, if you prefer it better 0.9.1.15...

[alexey123]

But I am already completely lost understanding about TheBrig versions. And I am afraid, not me only

I'm also not understand, what Matthew planed with such numbers.

May be replace number version on Unix time, when I repair anything?

But strangle conflict TheBrig and virtialbox not resolved

Thank you for your answer alexey123

IMHO this is OK too.

If you use bridge and auto birdge by Vbox, probably you cannot use it.
I'm using individual tap devices for VMs.

Not work on my machine:
bridge0 -> physical I/F such as re0 (LAN) -> VBox auto bridge
+-- mlxen0 (10GbE)
+-- wlan0 (wireless: run0)
+-- tap0, tap1, ...

Work (current setting):
bridge0 (assign as LAN)
+-- re0 (don't assign LAN nor OPT)
+-- mlxen0 (don't assign LAN nor OPT)
+-- wlan0 (don't assign LAN nor OPT)
+-- tap0, tap1, ...

I don't use jail on this machine, but epair might be same as tap.
Note: if you use MTU, you must have same size of MTU on all members of bridge.
Otherwise, large packet will be lost.
