（求助）移植IXP425到2.6.16网络不通

Question

大家好

请问一下我移植IXP425到2.6.16上...内核和文件系统都跑起来了...NPE驱动模块也正确加载好了...但是现在确出现了一个问题....扳子不能ping通外网..外网也不能ping通板子.....不明白是什么原因..望各位大侠指教...

其中板子和PC都是挂在同一台路由器下面，PC和板子属于同一网段内。。。使用的是直通线。。。PC端没有开放火墙。。。
板子ping自己能够通。。但是ping外网确不通。。。外网ping板子时在板子上ifconfig 可以看到

ixp1       Link encap:Ethernet  HWaddr 00:02:B3:02:02:02   
            inet addr:202.102.224.8  Bcast:202.102.224.255  
            Mask:255.255.255.0      UP BROADCAST MULTICAST  MTU:1500  Metric:1           
            RX packets:9 errors:0 dropped:0 overruns:0 frame:0  
            TX packets:0 errors:0 dropped:0 overruns:0 carrier:0    collisions:0 txqueuelen:256

Answer 1

tcpdump试试？？

Answer 2

什么叫外网？是指你的PC机还是别的什么？
只能收不能够发？
把PC ping扳子时的信息也那出来。系统启动信息。
再检查你是否真的使用的是直通线（用这个线换到PC上PING路由器）

Answer 3

外网就是我的PC 我在板子上ping 我的PC不通。。。。
使用我的PC  ping 板子也不行。。。。。

串口信息如下。。。

板子和PC都是通过直通线连接在一台路由器上面的。。。。把那根线换到PC上能够ping通路由器。。。

谢谢。。。

我也遇到同样的问题,前2天还是好的,晕死
我还发现,ixp0只能发不能收

那你解决了吗。。我把NPE驱动模块弄上去后。。。就是这样了。。。

以前网卡驱动这里改过

static int phyAddresses[IXP425_ETH_ACC_MII_MAX_ADDR] =
{
#if defined(CONFIG_ARCH_IXDP425)
    /* 1 PHY per NPE port */
    13, /* Port 1 (IX_ETH_PORT_1 / NPE B) */   //这里的13,14是改了的,以前是1,0改了据说就可以了,   
14  /* Port 2 (IX_ETH_PORT_2 / NPE C) */   //前2天好象还可以,用过tft下过东西,你看看.

Answer 7

那里的1和0好像只是表示一个代号。。。两块网卡。。。应该不会有太大的影响。。。
并且我的现在就是1和0。。

只是代号吗?我没仔细看,是别人改的,真的没什么影响,phyaddress没有什么影响吗?

我晕,我的又好了,吃了顿饭,就好了.....

我想这样的ixp0,还是ixp1选择一个,UP,另一个down,然后再去吃顿饭......
