[-- Attachment #1 --] I currently have a setup on a laptop where I have two aliases that I always want present. I would like to setup two aliases in /etc/dhclient.conf to handle having the Ethernet cable plugged in after boot, but dhclient has a limit of handling only one alias. /etc/rc.conf ifconfig_xl0="DHCP" ifconfig_xl0_alias0="inet 192.168.1.46 netmask 255.255.255.255" ifconfig_xl0_alias1="inet 192.168.6.46 netmask 255.255.255.0" The first address uses an alias-type netmask while the second is a private network I have for QEMU. I found that during PREINIT /sbin/dhclient-script is deleting the 192.168.1.46 address when it runs this: ifconfig $interface inet 0.0.0.0 netmask 0.0.0.0 broadcast 255.255.255.255 up A possible solution that works for me is to add an "alias" to this line. It appears to work, but I do not know if this would cause problems elsewhere or for other scenarios. Does anyone see any problems with this change? Sean P.S.
