[mrtg] cfgmaker generates wrong config for OpenBSD

[gnpf]

Hi,
I try to query my OpbenBSD firewalls with cfgmaker.
The generated config shows me wrong interface names/coun/addresses:

# ./cfgmaker --ifref=ip --global WorkDir:/var/www/mrtg/ public at fw1

WorkDir:/var/www/mrtg/

### Interface 1 >> Descr: 'lo0' | Name: '' | Ip: '10.100.102.98' | Eth: ''
###
### The following interface is commented out because:
### * it is a Software Loopback interface
### * has a speed of 0 which makes no sense

This is not the complete config, only the first 3 interfaces. ifconfig on
fw1 looks like:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33160
        priority: 0
        groups: lo
        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x10
em0: flags=8b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST> mtu
1500
        lladdr 00:15:17:d3:04:1d
        priority: 0
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        inet 10.100.102.98 netmask 0xffff0000 broadcast 10.100.255.255
        inet6 fe80::215:17ff:fed3:41d%em0 prefixlen 64 scopeid 0x1
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:15:17:d3:04:1c
        priority: 0
        media: Ethernet autoselect (1000baseT full-duplex)
        status: active
        inet 192.168.199.1 netmask 0xffffff00 broadcast 192.168.199.255
        inet6 fe80::215:17ff:fed3:41c%em1 prefixlen 64 scopeid 0x2

whats wrong here, where is my mistake? I try it with and without --ifref=ip,
everytime the same result.
I belive its a problem with openbsd, because I get the config from cisco and
linux devices without trouble.

thanks in advance,
tom
