今天發現ss掛了，我懷疑有電腦上的軟件把ss的IP上報了防火牆。我的路由器是WR720N，之前有刷過OpenWrt，於是想在這上面掛ss，這樣就沒有軟件收集數據了。
但是這個路由器的ROM非常小，只有4M。啥也不幹就70-80%了，甚至於update後直接滿了，於是我開始了各種刷機。網上也找了很多帖子，刷了很多說是有ss的固件，但是刷完後都沒有任何效果。不死鳥也刷不了，第一分區鎖了，解鎖的固件也沒找。網上有提到用U盤來放置app，這樣空間就很大了。
於是去找自帶usb的固件，也沒找到。各種碰壁之下，我決定去自己打包一個固件。
首先，我目前的固件版本是17.01.5，貌似官方的維護就停在這裏了。相關的網站在
https://archive.openwrt.org/releases/17.01.5/targets/ar71xx/generic/
最下面有一個包lede-imagebuilder-17.01.5-ar71xx-generic.Linux-x86_64.tar.xz下載下來，後續就靠它來生成我所需要的包。
由於系統是剛剛編譯完petaLinux的狀態，所以好像編譯所需的東西都是齊的。
解壓後直接編譯。
make info
會顯示出支持的機型型號
我的是tl-wr720n-v4
所以編譯命令就是
make image PROFILE=tl-wr720n-v4
一次過。
開頭有這樣一段話：
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
這就是固件裏包括的軟件了。
編譯完後可以看出來是個比較基礎的固件。GUI也沒有。暫時先不要GUI，等把U盤搞定了再來搞GUI。
參考 [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，要像擴展U盤，就得需要這幾個包：
block-mount kmod-fs-ext4 kmod-usb-storage
那麼就把這幾個包包括上一起打包
make image PROFILE=tl-wr720n-v4 PACKAGES="block-mount kmod-fs-ext4 kmod-usb-storage"
接下來使用scp拷貝到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 [email protected]:/tmp
接下來ssh到WR720上，用sysupgrade來升級固件。
sysupgrade /tmp/lede-17.01.5-ar71xx-generic-tl-wr720n-v4-squashfs-sysupgrade.bin
升級完成後，燈常亮了，無法ssh上去。我一度懷疑是刷成磚頭了，萬不得已，重啓一次後就可以了，有點嚇人。
用lsmod查看內核是不是加進去了。
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
這個ext4應該就是了。話說他自己難道沒兩個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)
別說，還真沒有。
接下來繼續檢查
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
最後一個直接來運行一下。
U盤是我提前在Linux上處理過的，直接刪除所有分區，創建一個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，打開3G開關。然後運行
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"
將sda1的uuid和sd3的uuid記錄下來。
編輯配置文件。
vi /etc/config/fstab
內容最終如下：
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'
那兩個不開啓的mount不知道是做什麼的，先不刪除了。留着，不開啓應該就行了。
SWAP分區先不設置，感覺哪裏不對勁。先不用它。
加下來掛載sda1，
mount /dev/sda1 /mnt
但是掛載完成後，mnt變成不可讀寫的了，不能cd進去：
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
不知道是什麼原因，卸載後在掛載又可以了？再來幾次。
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#
看起來沒有問題了。
接下來擴展到優盤上。

我着實懷疑，就這麼幾個文件？
仔細對照了一下還真就這麼幾個文件。
行了，現在重啓後，overlay應該就是從U盤掛載過來的了。
有點緊張，我沒有編程器。。。
reboot
看到藍燈在閃，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)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600)
/dev/sda3 on /mnt/sda3 type ext4 (rw,relatime,data=ordered)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)
嗯，看起來已經大功告成了？
再看看大小
df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 2.3M 2.3M 0 100% /rom
tmpfs 13.7M 52.0K 13.7M 0% /tmp
/dev/sda1 954.6M 1.4M 887.9M 0% /overlay
overlayfs:/overlay 954.6M 1.4M 887.9M 0% /
tmpfs 512.0K 0 512.0K 0% /dev
/dev/sda3 27.4G 43.9M 25.9G 0% /mnt/sda3
這個爽。
接下來先讓它能上網。還好我有USB網卡一張，先讓主機上網，然後虛擬機也能上網，然後再通過USB網口鏈接W720的WAN口，絕對可行的。但是，，怎麼知道它從我這裏獲取了什麼IP走呢？查了半天，都說在var下，但是就是沒找到，然後找到了這個命令 ARP，這個好像是可以監聽的？？
arp -a
? (192.168.150.254) at 00:50:56:e4:28:30 [ether] on ens33
插上網線
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
馬上就找出了它的IP，連上去。
ssh [email protected]
ssh: connect to host 10.42.0.187 port 22: Connection refused
這就很尷尬了，居然被拒絕了。
有可能的情況是，這個設備默認是不允許外網來ssh到路由器上的。
那隻能連在lan口上，先把權限打開吧。
具體參考這裏ssh連接公司內網
vi /etc/config/firewall
最後增加
config rule
option name 'Allow-wan-ssh'
option src 'wan'
option proto 'tcp'
option dest_port '22'
option target 'ACCEPT'
OK
ssh
ssh [email protected]
BusyBox v1.25.1 () built-in shell (ash)

還是失敗，看起來網絡不是很好，等下再來update。
終於成功了，安裝LUCI把。參考OpenWRT系列教程之 WEB管理界面安裝——LUCI

多了一個br-lan，這是啥玩意，我仔細一想，這不就是LAN口麼。應該是要插在LAN口上訪問WEB
果然可以了。
不過裝的東西有點多，有點卡，這樣就算是大功告成了。網線切到路由上。啥也不說，先看看剩餘空間
我還能說啥，配置網絡，打開SWAP，關閉wan口的ssh，安裝一下中文，然後發現一點兒也不卡？說明還行啊。
剩下的就是安裝ss了。有空再說。
