prl_dhcp Can not bind to en2

Ok, ever since I brought RC2 at work and used wired network, I lost the ability to use automatic / dhcp configuration of the parallels guest interface (it shows up "red" in mac os network) I have to manually set an ip address on both side as the only painful workaround

I have the following in my console syslog which I guess is a clue:

Jun 1 20:14:37 Laurent-Macbook kernel[0]: com_parallels_kext_Pvsvnic: Ethernet address 00:01:23:45:67:89
Jun 1 20:14:37 Laurent-Macbook prl_dhcp[1082]: Can not bind to en2.
Jun 1 20:14:41 Laurent-Macbook mDNSResponder: Repeated transitions for interface en2 (FE80:0000:0000:0000:0201:23FF:FE45:6789); delaying packets by 5 seconds

I tried uninstalling and resinstalling, clearing some .plist preferences,... to no avail

How do I get dhcp back working ?

Thanks
Laurent

ps: other than that I love the product, paid for it a while ago already
(I also submitted a support request about this but got no reply yet)
 
I'm trying various settings for the parallels interface (bootp instead of dhcp) and now I get the dhcp to crash !:

Help or howto reset the networking/dhcp to 'clean' state would be greatly appreciated
 
another clue maybe, I do not have the bootp option set for en2 (parallels guest interface) but I have DHCP, nevertheless upon reboot I see:

Jun 1 21:00:54 Laurents-Macbook bootpd[131]: interface en2: ip 192.168.2.1 mask 255.255.255.0

in my log - any idea why ? maybe that's why DCHP doesn't work ?

wpa enterprise!

Ok, on my home network, I managed to get the networking and dhcp to work/not crash,
so looks like the problem is linked to WPA Enterprise setup that we have at work

parallels team: maybe that will help you reproduce this/fix this problem, let me know if you need more information

last semi related strangeness: even though dhcp now configures the en2 interface ok to 10.37.129.2 somehow it seems that internet sharing (NAT like workaround) causes bootp to be running on that interface and somehow pick 192.168.2.1 as the mac ip and 192.168.2.4 as the vm's ip... Why do we need prl_dhcp at all then (anyway to turn it off?) ?
 
Laurent,

Just a quick check: did you reboot your Mac after installing Parallels? If not, try it.

First of all en2 should be configured to use DHCP. What happens if you do 'sudo /Library/StartupItems/Parallels/prl_dhcpd' from a terminal and then 'tail /var/log/system.log'? Does prl_dhcpd bark at en2 this time?

Re your last question: when you turn on IS on the Mac prl_dhcpd keeps silence and allows bootpd to do the job.
 
Yes I rebooted many times to no avail; it only fixed itself after I left my work were the connection is WPA enterprise wifi and got home where I have simple WEP
