openwrt+dhcpv6

在OpenWrt上配置DHCPv6是实现IPv6连接的一种常见方法。下面是一个简单的示例来演示如何在OpenWrt上配置DHCPv6。

1. 首先，确保你已经安装了OpenWrt并成功登录到路由器的管理界面。

2. 打开网络设置页面，找到WAN口的配置。

3. 在WAN口的配置页面中，找到IPv6设置部分。

4. 选择"DHCPv6 client"作为IPv6协议。

5. 确保"Request IPv6-address"和"Request IPv6-prefix of length"选项都被勾选。

6. 保存并应用配置。

7. 重新启动路由器或者重新连接WAN口。

8. 等待一段时间，路由器会自动获取到IPv6地址和前缀。

9. 检查WAN口的状态页面，确认是否成功获取到IPv6地址和前缀。

10. 现在你的OpenWrt路由器已经成功配置了DHCPv6，可以通过IPv6连接上网了。

openwrt dhcpv6

OpenWrt supports DHCPv6 for IPv6 address assignment and configuration. To enable DHCPv6 on OpenWrt, you need to install the necessary packages and configure the DHCPv6 server.

Here's a step-by-step guide to setting up DHCPv6 on OpenWrt:

1. Log in to your OpenWrt router's web interface or connect to it via SSH.
2. Install the required packages by running the following command:

   opkg update
   opkg install odhcpd-ipv6only

3. Edit the DHCPv6 server configuration file by running the command:

   vi /etc/config/dhcp

4. In the `config dhcp 'lan'` section, add or modify the following lines:

openwrt+uclibc+valgrind，怎么操作valgrind才可以正常运行

在 OpenWrt 上使用 Valgrind 需要注意以下几点：

1. 安装 Valgrind

可以通过 opkg 安装 Valgrind：

opkg update
opkg install valgrind

2. 配置 Valgrind

默认情况下，Valgrind 会使用 glibc 库，而 OpenWrt 中使用的是 uClibc 库，因此需要手动配置 Valgrind。

首先，需要创建一个文件 `/etc/valgrindrc`，并添加以下内容：

# Valgrind configuration file for uClibc
libc-libraries: /lib/libuClibc-*.so.*

然后，在运行 Valgrind 时，需要指定使用该配置文件：

valgrind --tool=memcheck --vgdb=no --trace-children=yes --num-callers=20 --suppressions=/usr/lib/valgrind/uClibc.supp --read-var-info=yes --malloc-fill=0xFE --free-fill=0xEF --leak-check=full --show-reachable=yes --track-origins=yes --log-file=/tmp/valgrind.log --error-limit=no --undef-value-errors=no --gen-suppressions=all --fair-sched=yes --quiet --trace-children=yes

这里的参数根据需求来调整。

3. 运行 Valgrind

使用 `valgrind` 命令即可运行 Valgrind，例如：

valgrind --tool=memcheck --leak-check=full myprogram arg1 arg2

这里的 `myprogram` 是需要测试的程序，`arg1`、`arg2` 是该程序的参数。

注意：Valgrind 会对程序的运行速度有一定的影响，因此在测试时需要对程序进行压力测试，以确保测试结果的准确性。
