I tried the whole rest of this evening, but I do not get this...
Default config after boot - without running any robocfg script - is:
gayatri:~# robocfg show
Switch: enabled
Port 0(W): 100FD enabled stp: none vlan: 1 mac: 00:00:00:00:00:00
Port 1(4): 100FD enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
Port 2(3): DOWN enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
Port 3(2): DOWN enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
Port 4(1): DOWN enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
Port 5(C): 100FD enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
VLANs: BCM5325/535x enabled mac_check mac_hash
vlan0: 1 2 3 4 5u
vlan1: 0 5u
vlan2:
vlan3:
vlan4:
vlan5:
vlan6:
vlan7:
vlan8:
vlan9:
vlan10:
vlan11:
vlan12:
vlan13:
vlan14:
vlan15:
And I have:
gayatri:~# ip addr
1: lo: <LOOPBACK> mtu 16436 qdisc noop
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen
1000
link/ether 00:1e:8c:2e:0f:51 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.11/24 brd 10.0.0.255 scope global eth0
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
link/ether 40:10:18:00:00:2d brd ff:ff:ff:ff:ff:ff
4: eth0.1 at eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue
link/ether 00:1e:8c:2e:0f:51 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.8/24 brd 10.0.0.255 scope global eth0.1
With this I have both IP addresses (10.0.0.8 and 10.0.0.11) on LAN ports 1
to 4, but *not* on the WAN port (the above output was with both the WAN
and the LAN port connected).
When I now run this script which is based upon your comments above I get:
gayatri:~# cat /usr/local/bin/switch-config
#!/bin/bash
# 4 Port Switch + WAN Port
robocfg switch disable
robocfg vlans enable reset
# WAN-Port
robocfg vlan 0 ports "0 5u"
# LAN-Ports
robocfg vlan 1 ports "1 2 3 4 5t"
robocfg switch enable
I get:
gayatri:~# robocfg show
Switch: enabled
Port 0(W): 100FD enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
Port 1(4): 100FD enabled stp: none vlan: 1 mac: 00:00:00:00:00:00
Port 2(3): DOWN enabled stp: none vlan: 1 mac: 00:00:00:00:00:00
Port 3(2): DOWN enabled stp: none vlan: 1 mac: 00:00:00:00:00:00
Port 4(1): DOWN enabled stp: none vlan: 1 mac: 00:00:00:00:00:00
Port 5(C): 100FD enabled stp: none vlan: 0 mac: 00:00:00:00:00:00
VLANs: BCM5325/535x enabled mac_check mac_hash
vlan0: 0 5u
vlan1: 1 2 3 4 5t
And now both IP addresses are on the WAN port and not on the WAN port.
Even after /etc/init.d/networking restart.
This is whats in there:
gayatri:~# cat /etc/network/interfaces
# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.
auto lo
iface lo inet loopback
#pre-up /usr/local/bin/switch-config
# WAN-Port
auto eth0
iface eth0 inet static
address 10.0.0.11
netmask 255.255.255.0
broadcast 10.0.0.255
gateway 10.0.0.9
# LAN-Ports
auto eth0.1
iface eth0.1 inet static
address 10.0.0.8
netmask 255.255.255.0
broadcast 10.0.0.255
gateway 10.0.0.9
In above output of robocfg those null MAC addresses look suspicious to me.
Also I am not sure whether eth0 and eth0.1 should have the same mac
address.
gayatri:~# ifconfig
eth0 Protokoll:Ethernet Hardware Adresse 00:1E:8C:2E:0F:51
inet Adresse:10.0.0.11 Bcast:10.0.0.255 Maske:255.255.255.0

So I tried manually. I did ifdown eth0.1 and then
vconfig add eth0 1
Set a different MAC address:
ifconfig eth0.1 hw ether 00:1E:8C:2E:0F:52
And configured my IP address to it:
ifconfig eth0.1 10.0.0.8 netmask 255.255.255.0 broadcast 10.0.0.255
It did come a bit closer to what I want to achieve, but still it doesn't
work correctly. Now I had it that on the WAN port both IP addresses where
and on the LAN ports one. But I also had added a VLAN 0...
I then configure that other IP address on VLAN 0 and removed the IP
address from eth0. But it all did not work. Now it was all on the LAN
ports and I didn't understand a bit of it at all.
I am no switch guru - actually this is the first hardware switch I
attempted to configure. I only did a Linux bridge before.
Can you give a concrete example? Can it be done entirely
within /e/n/interfaces - except the switch-config script? I tried
auto lo
iface lo inet loopback
pre-up /usr/local/bin/switch-config
but then loopback interface was not configured at all after start and
robocfg showed the factory details.
Basically I like to have:
- WAN port: no IP address at all, only pppoe
- LAN port: IP 10.0.0.9/24 in the end, temporarily 10.0.0.8/24
What I do have to feed into robocfg and /e/n/i or some other start script
in order to make it happen?
What foomagic do I have to master? Maybe I should leave out /e/n/i
completely and do it all in a custom script? Actually I'd like to use
standard Debian way of network configuration as much as possible.
Installing and customizing Debian for my needs on the ASUS has been easy
so far. I already have bzr running - from etch-backports and screen
configured and vim and stuff... But I am completely stuck at that
robocfg. Basically I think my problem is that I do not have a frigging
clue on how this tool works.
I leave it now. I think I could go trying around for ages without finding
the obvious.
Ciao,
