在Solaris系统中，修改tcp/ip配置是比较繁琐的事情
本机机器名 /etc/hostname.pcn0
指向/etc/inet/hosts的软链接，记录IP地址和机器名的对应关系 /etc/hosts
指向/etc/inet/netmasks的软链接,记录网络地址和子网掩码的对应关系 /etc/netmasks
默认网关 /etc/defaultrouter

默认ftp服务是启动的，但不允许root访问，这个问题困扰我1周时间了，开始一直改的是sshd的配置文件，后来又google了很久，发现应该改ftpd的配置文件。
让root能够登录，需要修改/etc/ftpd/ftpusers,将root用户注释掉，此文件夹下包含所有被拒绝访问的用户
# cd /etc/ftpd # pwd
/etc/ftpd
# more ftpusers
# ident "@(#)ftpusers 1.5 04/02/20 SMI"
#
# List of users denied access to the FTP server, see ftpusers(4).
