系统内核:
mc:/etc/init.d# uname -r
2.4.27-2-386
服务器 ELL PowerEdge 2850 双千兆集成网卡
网卡信息如下:
mc:/etc/init.d#ifconfig
eth0 Link encap:Ethernet HWaddr 00:13:72:61:C8:C3

其中只有第一块网卡有接网线 速度是100M的 IP地址为210.34.143.101
interfaces文件内容如下:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 210.34.143.101
network 210.34.143.0
netmask 255.255.255.0
broadcast 210.34.143.255
gateway 210.34.143.1
装完初始系统发现如下问题
其他网段比如说219.228.228.*都可以PING通服务器而且几乎没什么延迟
如:

同网段其它机器ping时显示信息如下:

Request timeout

有时设置连不通
但只要在服务器段ping下这网段里随便一个可用IP
那同网段内机子再ping服务器就短时间正常 过段时间又出现上面那种情况
刚有APT install 了个内核2.6.8-12-em64t-p4-smp 问题依旧
这个问题好奇怪 连续搞了一周还没搞定 今天搞到现在半夜了还没理出个头绪
google 了好久 找到个症状相试的

可惜也没解决办法 希望高人指点 谢谢! |
