wide-dhcp6c(3)

截止目前为止，还能够正常使用wide-dhcp6c。原因，暂时找不到原因在哪里。只有通过打印日志来看。一直怀疑是配置文件出错了，但是也没看到过一个可以使用的配置文件，dhcp6c.conf. 都是example等等，附加e文和缩写。虽然看过，也是很粗糙的理解其意思。

先修改一下cftoken.l，将yywrap在cfdebug_print函数之前补上，这样make clean ，再make的时候，就不用再生成的cftoken.c 里面加了。

int yywrap()
{return 1;
}static void
cfdebug_print(w, t, l)char *w, *t;int l;
{if (w) {dprintf(LOG_DEBUG, FNAME,"<%d>%s [%s] (%d)", yy_start, w, t, l);} else {dprintf(LOG_DEBUG, FNAME,"<%d>[%s] (%d)", yy_start, t, l);}
}

另外将YYDEBUG这个宏打开，设置为1。同时将全局变量yydebug 也在最开始的地方赋值为1. 这样就可以看到过程中哪里分析错误了。

执行程序后，可以看到貌似是下一步的分析出错，reading a token: Next token is STRING(),看样子是这里分析文件出错了。

那么还是配置文件的问题。。。

待续

配置出来了，配置文件其实也很简单。e文不太好，看了半天很多的看了也似懂非懂的。

然后参考了

www.infradead.org/~tgr/libnl/

上面写的一大堆东西，也没看懂多少。

就是dhcp6c.conf简单的配置文件如下，原先的时候添加几个其他的配置信息，结果反而一大堆错误

interface eth0 {send ia-na 0;
};id-assoc na{
};

然后从日志信息来看

以及敲击iconfig，地址都是配置上了。看来兜了好几天的空闲时间。这边用的是美国netgear作为ipv6分配的服务器。看样子是ok的。。。。
