WR720N改造记录1

今天发现ss挂了，我怀疑有电脑上的软件把ss的IP上报了防火墙。我的路由器是WR720N，之前有刷过OpenWrt，于是想在这上面挂ss，这样就没有软件收集数据了。
但是这个路由器的ROM非常小，只有4M。啥也不干就70-80%了，甚至于update后直接满了，于是我开始了各种刷机。网上也找了很多帖子，刷了很多说是有ss的固件，但是刷完后都没有任何效果。不死鸟也刷不了，第一分区锁了，解锁的固件也没找。网上有提到用U盘来放置app，这样空间就很大了。

于是去找自带usb的固件，也没找到。各种碰壁之下，我决定去自己打包一个固件。
首先，我目前的固件版本是17.01.5，貌似官方的维护就停在这里了。相关的网站在

https://archive.openwrt.org/releases/17.01.5/targets/ar71xx/generic/

最下面有一个包lede-imagebuilder-17.01.5-ar71xx-generic.Linux-x86_64.tar.xz下载下来，后续就靠它来生成我所需要的包。
由于系统是刚刚编译完petaLinux的状态，所以好像编译所需的东西都是齐的。
解压后直接编译。

make info

会显示出支持的机型型号
我的是tl-wr720n-v4
所以编译命令就是

make image PROFILE=tl-wr720n-v4

一次过。
开头有这样一段话：

Building images for ar71xx - TP-LINK TL-WR720N v4
Packages: base-files busybox dnsmasq dropbear firewall fstools ip6tables iptables kernel kmod-ath9k kmod-gpio-button-hotplug kmod-usb-core kmod-usb2 libc libgcc logd mtd netifd odhcp6c odhcpd opkg ppp ppp-mod-pppoe swconfig uboot-envtools uci uclient-fetch wpad-mini

这就是固件里包括的软件了。
编译完后可以看出来是个比较基础的固件。GUI也没有。暂时先不要GUI，等把U盘搞定了再来搞GUI。
参考 [文章] (https://www.coldawn.com/tl-wr703n-tl-wr720n-official-openwrt-barrier_breaker-14-07-extroot-rootfs-on-remove-disk/)
可以得知，要像扩展U盘，就得需要这几个包：

block-mount kmod-fs-ext4 kmod-usb-storage

那么就把这几个包包括上一起打包

make image PROFILE=tl-wr720n-v4 PACKAGES="block-mount kmod-fs-ext4 kmod-usb-storage"

接下来使用scp拷贝到WR720N的tmp下。

scp build_dir/target-mips_24kc_musl-1.1.16/linux-ar71xx_generic/tmp/lede-17.01.5-ar71xx-generic-tl-wr720n-v4-squashfs-sysupgrade.bin root@192.168.1.1:/tmp

接下来ssh到WR720上，用sysupgrade来升级固件。

sysupgrade /tmp/lede-17.01.5-ar71xx-generic-tl-wr720n-v4-squashfs-sysupgrade.bin

升级完成后，灯常亮了，无法ssh上去。我一度怀疑是刷成砖头了，万不得已，重启一次后就可以了，有点吓人。

用lsmod查看内核是不是加进去了。

lsmod | grep ext4
crc16                    992  1 ext4
crypto_hash             8960  3 ext4,jbd2,crc32c_generic
ext4                  320128  0
jbd2                   47056  1 ext4
mbcache                 4208  1 ext4

这个ext4应该就是了。话说他自己难道没两个ext4？

mount
/dev/root on /rom type squashfs (ro,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,noatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)
/dev/mtdblock3 on /overlay type jffs2 (rw,noatime)
overlayfs:/overlay on / type overlay (rw,noatime,lowerdir=/,upperdir=/overlay/upper,workdir=/overlay/work)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,size=512k,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)

别说，还真没有。
接下来继续检查

lsmod | grep usb
nls_base                4704  1 usbcore
scsi_mod               86192  2 usb_storage,sd_mod
usb_common              1952  1 usbcore
usb_storage            37216  0
usbcore               116432  3 usb_storage,ehci_platform,ehci_hcd

最后一个直接来运行一下。
U盘是我提前在Linux上处理过的，直接删除所有分区，创建一个1G的EXT4，格式化；1G的SWAP；剩下的全是EXT4，格式化。全部不加Label。插在USB接口上，打开3G开关。然后运行

block info
/dev/mtdblock2: UUID="251cd5f9-f6e5c94a-5c3ff123-65a0ac72" VERSION="4.0" MOUNT="/rom" TYPE="squashfs"
/dev/mtdblock3: MOUNT="/overlay" TYPE="jffs2"
/dev/sda1: UUID="f02abc98-515a-45ce-a66c-9c3785a6cf00" VERSION="1.0" TYPE="ext4"
/dev/sda3: UUID="f746984a-376f-41e2-b6bf-92feb40f6d48" VERSION="1.0" TYPE="ext4"

将sda1的uuid和sd3的uuid记录下来。
编辑配置文件。

vi /etc/config/fstab

内容最终如下：

config 'global'                                                                                                                       option  anon_swap       '0'                                                                                                   option  anon_mount      '0'                                                                                                   option  auto_swap       '1'                                                                                                   option  auto_mount      '1'                                                                                                   option  delay_root      '5'                                                                                                   option  check_fs        '0'                                                                                                   config 'mount'                                                                                                                        option  target  '/mnt/sda1'                                                                                                   option  uuid    'A1BB-B639'                                                                                                   option  enabled '0'                                                                                                           config 'mount'                                                                                                                        option  target  '/mnt/sda2'                                                                                                   option  uuid    '640ad362-77b2-4374-b6c2-1402a449fa3b'                                                                        option  enabled '0'                                                                                                           config 'mount'                                                                                                                        option target '/overlay'                                                                                                      option uuid 'f02abc98-515a-45ce-a66c-9c3785a6cf00'                                                                            option enabled '1'                                                                                                            config 'mount'                                                                                                                        option target '/mnt/sda3'                                                                                                     option uuid 'f746984a-376f-41e2-b6bf-92feb40f6d48'                                                                            option enabled '1'

那两个不开启的mount不知道是做什么的，先不删除了。留着，不开启应该就行了。
SWAP分区先不设置，感觉哪里不对劲。先不用它。

加下来挂载sda1，

mount /dev/sda1 /mnt

但是挂载完成后，mnt变成不可读写的了，不能cd进去：

root@LEDE:~# mount /dev/sda1 /mnt
root@LEDE:~# cd mnt
-ash: cd: can't cd to mnt
root@LEDE:~# cd mnt
-ash: cd: can't cd to mnt

不知道是什么原因，卸载后在挂载又可以了？再来几次。

root@LEDE:/# umount /dev/sda1
root@LEDE:/# mount /dev/sda1 /mnt
root@LEDE:/# cd /mnt
root@LEDE:/mnt# ls
lost+found
root@LEDE:/mnt# mkdir 123
root@LEDE:/mnt# ls
123         lost+found
root@LEDE:/mnt# rmdir 123
root@LEDE:/mnt# ls
lost+found
root@LEDE:/mnt#

看起来没有问题了。
接下来扩展到优盘上。

我着实怀疑，就这么几个文件？
仔细对照了一下还真就这么几个文件。
行了，现在重启后，overlay应该就是从U盘挂载过来的了。
有点紧张，我没有编程器。。。

reboot

看到蓝灯在闪，我就放心了。

mount
/dev/root on /rom type squashfs (ro,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,noatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)
/dev/sda1 on /overlay type ext4 (rw,relatime,data=ordered)
overlayfs:/overlay on / type overlay (rw,noatime,lowerdir=/,upperdir=/overlay/upper,workdir=/overlay/work)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,size=512k,mode=755)

/dev/sda3 on /mnt/sda3 type ext4 (rw,relatime,data=ordered)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)

嗯，看起来已经大功告成了？
再看看大小

df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                 2.3M      2.3M         0 100% /rom

/dev/sda3                27.4G     43.9M     25.9G   0% /mnt/sda3

这个爽。
接下来先让它能上网。还好我有USB网卡一张，先让主机上网，然后虚拟机也能上网，然后再通过USB网口链接W720的WAN口，绝对可行的。但是，，怎么知道它从我这里获取了什么IP走呢？查了半天，都说在var下，但是就是没找到，然后找到了这个命令 ARP，这个好像是可以监听的？？

arp -a
? (192.168.150.254) at 00:50:56:e4:28:30 [ether] on ens33

插上网线

arp -a
? (192.168.150.254) at 00:50:56:e4:28:30 [ether] on ens33
? (10.42.0.187) at 50:fa:84:a1:10:a5 [ether] on enx000ec6dea37f

马上就找出了它的IP，连上去。

ssh root@10.42.0.187
ssh: connect to host 10.42.0.187 port 22: Connection refused

这就很尴尬了，居然被拒绝了。
有可能的情况是，这个设备默认是不允许外网来ssh到路由器上的。
那只能连在lan口上，先把权限打开吧。
具体参考这里ssh连接公司内网

vi /etc/config/firewall

最后增加

config rule                                            option name 'Allow-wan-ssh'                    option src 'wan'                               option proto 'tcp'                             option dest_port '22'                          option target 'ACCEPT'

OK
ssh

嘿嘿嘿，行了。update一下看有没有增加ROM使用量。（opkg.conf 设置在Overlay上，所以是不会增加ROM使用量的）

看起来有点错误，看看文件存不存在把。然后我发现是我自己的网络问题，重新update
还是失败，看起来网络不是很好，等下再来update。
终于成功了，安装LUCI把。参考OpenWRT系列教程之 WEB管理界面安装——LUCI

多了一个br-lan，这是啥玩意，我仔细一想，这不就是LAN口么。应该是要插在LAN口上访问WEB
果然可以了。
不过装的东西有点多，有点卡，这样就算是大功告成了。网线切到路由上。啥也不说，先看看剩余空间

我还能说啥，配置网络，打开SWAP，关闭wan口的ssh，安装一下中文，然后发现一点儿也不卡？说明还行啊。
剩下的就是安装ss了。有空再说。
