搞定！如下：
/etc/hosts
127.0.0.1 localhost
210.xxx.xx1.xx dbs loghost
192.168.9.15 mytestip
192.168.9.65 mytestip2

/etc/netmasks
210.xx.xx.0 255.255.255.0
192.168.9.0 255.255.255.192
192.168.9.64 255.255.255.252

/etc/hme0
dbs
/etc/hme0:1
mytestip
/etc/hme0:2
mytestip2

#init 6

...

#ifconfig -a
lo0: flags=1000849 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
hme0: flags=1000843 mtu 1500 index 2
inet 210.xxx0.2xx.xx netmask ffffff00 broadcast 210.82.31.255
hme0:1: flags=1000843 mtu 1500 index 2

1. How can I bind multiple (virtual) IP addresses to a single network interface card ?

The following steps demonstrate how to configure the ethernet (elx0) device to support more than one IP address.

Create a text file in the /etc directory called hostname.elx0:1 and add this entry to file:
virtual

Add this IP address and hostname in the /etc/hosts file:
10.0.0.1 virtual

Create a new script file in the /etc/rc2.d directory called S70virtual, and add these entries in this file (for permanent change):
ifconfig elx0:1 10.0.0.1 up netmask 255.255.255.0

Reboot the system.
To delete a logical interface, use the unplumb command . For example,

example% ifconfig elx0:1 down unplumb will delete the logical interface elx0:1.
