ipvsadm - 如何显示主机名和端口？

Question

上例一中ipvs规则的输出如下：

[root@penguin sbin]# ipvsadm -ln
IP Virtual Server version 1.0.8 (size=65536)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  207.175.44.110:80 rr
  -> 192.168.10.5:80              Masq    1      0          0
  -> 192.168.10.4:80              Masq    1      0          0
  -> 192.168.10.3:80              Masq    1      0          0
  -> 192.168.10.2:80              Masq    1      0          0
  -> 192.168.10.1:80              Masq    1      0          0

我只想显示主机名和端口（不是 IP 和端口）。示例：

[root@penguin sbin]# ipvsadm -ln
IP Virtual Server version 1.0.8 (size=65536)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  207.175.44.110:80 rr
  -> webserver-01:80              Masq    1      0          0
  -> webserver-02:80              Masq    1      0          0
  -> webserver-03:80              Masq    1      0          0
  -> webserver-04:80              Masq    1      0          0
  -> webserver-05:80              Masq    1      0          0

请帮助我。

你试过了吗

ipvsadm -l

?

根据手册页：

-n, --数字

  Numeric output.  IP addresses and port numbers will  be  printed
  in  numeric  format  rather  than  as as host names and services
  respectively, which is the  default.   --exact  Expand  numbers.
  Display  the  exact  value  of  the  packet  and  byte counters,
  instead  of only the rounded number in K’s (multiples  of  1000)
  M’s  (multiples  of  1000K)  or G’s (multiples  of 1000M).  This
  option is only relevant for the -L command.
