==》1)重启网络：sudo /etc/init.d/network restart
==》2)SLES上修改网络通过yast2
==》3)RHEL上修改网络通过setup
==》4)检查接口是否已被用telnet <IP> <port>
==》5)ifconfig eth0:0 9.189.88.175 netmask 255.255.255.0 up
==》6)sudo /etc/init.d/xinetd restart
==》7)检查网络状态
netstat -an |grep -c TIME_WAIT
netstat -anp|grep 80
查找占用80端口的process
==》8)网络相关问题

* iv) FireWall on SLES
*
* ----open port 8070 to access AppBuilder:
* Perform. the following as "root" - from the idcuser, "sudo su -"
* Edit /etc/sysconfig/SuSEfirewall2 file,
* Add 8070 to the following line (space separated ): FW_SERVICES_EXT_TCP="22 80 443 2809 8880 9401 9403 9402 9060"
* Recycle the firewall, execute “/sbin/SuSEfirewall2 stop” then “/sbin/SuSEfirewall2 start”
* ----yast -> Security and Users -> Firewall
