求助！！！

我们这上网需要运行arp -s 211.81.54.1 00-05-5e-2f-7d-02（在xp下）
不知在redhat9.0下该怎么运行
谢谢！！！

一样的：

       -s hostname hw_addr, --set hostname
              Manually create an ARP address mapping entry for  host  hostname
              with hardware address set to hw_addr class, but for most classes
              one can assume that the usual presentation can be used.  For the
              Ethernet  class,  this  is  6 bytes in hexadecimal, separated by
              colons. When adding proxy arp entries (that is  those  with  the
              publish  flag  set  a  netmask may be specified to proxy arp for
              entire subnets. This is not good practice, but is  supported  by
              older  kernels because it can be useful. If the temp flag is not
              supplied entries will be permanent stored into the ARP cache.
              NOTE: As of kernel 2.2.0 it is no longer possible to set an  ARP
              entry  for  an entire subnet. Linux instead does automagic proxy
              arp when a route exists and it is  forwarding.  See  arp(7)  for
              details.
