Synthetic NIC does not acquire a DHCP address when set to “DHCP” #1

Open nickme opened 12 years ago

nickme commented 12 years ago 
Environment:
    Standalone W2K8 R2 server.
    VM with FreeBSD 8.2 and the enlightenment drivers installed

Add a synthetic NIC to the VM, then boot the VM
Configuring synthetic NIC for automatic DHCP configuration
Edit /etc/rc.conf and add following line
    ifconfig_hn0=”DHCP”
Reboot the VM

No IP address is assigned to hn0
After logging in, the command “dhclient hn0” completes successfully

Modifying /etc/rc.conf to the following
    ifconfig_hn0=”SYNCDHCP”
Reboot the VM

This works, but UDP errors are present
    bsdtest# ifconfig hn0 up
    bsdtest# dhclient hn0

Can repeat this on Hyper-V on Windows 8.1 with FreeBSD 10.0 as well.
