看上去开了很多 ssh 端口，开启 -p- 从新扫了一次，扫描出更多 ssh 端口
尝试用连贯下面的 ssh 端口，会一直的提醒 Higher 或者lower
咱们当然不须要一个个端口去测试，只须要不停的折半查找，那么在对数次数内咱们就能够找到实在端口

Enter Secret:当初咱们拿到一个加密文本。Jabberwocky在爱丽丝的故事里是一首废话诗
对于这个背景能够参考维基百科
依据下面的背景常识咱们能够拿到一段明文：
'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe
All mimsy were the borogoves,
And the mome raths outgrabe.对应的密文就是下面的第一段：
'Mdes mgplmmz, cvs alv lsmtsn aowil
Fqs ncix hrd rxtbmi bp bwl arul;
Elw bpmtc pgzt alv uvvordcet,
Egf bwl qffl vaewz ovxztiql.咱们猜想这里用的是维吉利亚加密，那么在晓得明文和密文的状况下，咱们如何晓得加密的秘钥？
我搜寻到了这个页面
这里说了一句:
Take the ciphertext and decrypt it with the plaintext as the key. If it was vigenere, you’ll see the real key pop out. Which is the case here.
用明文作为秘钥，解密已加密的文本，得进去的就是秘钥
去到这个网站
咱们把头两行加密文本去除标点当前作为待解密文本：MdesmgplmmzcvsalvlsmtsnaowilFqsncixhrdrxtbmibpbwlarul
把头两行的明文去除标点当前作为解密的秘钥:TwasbrilligandtheslithytovesDidgyreandgimbleinthewabe
解密进去当前是：ThealphabetcipherthealphabetCipherthealphabetcipherth
咱们察看，期中 thealphabetcipher 这个字符串在解密密文里重复呈现，所以这个就是咱们的解密秘钥
咱们用下面的秘钥解密整个加密诗文
Twas brillig, and the slithy toves
Did gyre and gimble in the wabe;
All mimsy were the borogoves,
And the mome raths outgrabe.
'Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!'
He took his vorpal sword in hand:
Long time the manxome foe he sought--
So rested he by the Tumtum tree,
And stood awhile in thought.
And as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
And burbled as it came!
One, two! One, two! And through and through
The vorpal blade went snicker-snack!
He left it dead, and with its head
He went galumphing back.
'And hast thou slain the Jabberwock?
Come to my arms, my beamish boy!
O frabjous day! Callooh! Callay!'He chortled in his joy.'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe;
All mimsy were the borogoves,
And the mome raths outgrabe.

alice不能应用 sudo -l，因为不晓得明码
有一个 txt 文件，然而没有什么卵用不必管
全局寻找 alice 相干的文件
alice@looking-glass:/$ find / -name *alice* -type f 2>/dev/null
/etc/sudoers.d/alice
````
查看这个文件, 能够应用 bashalice@looking-glass:/$ cat /etc/sudoers.d/alice
alice ssalg-gnikool = (root) NOPASSWD: /bin/bash
在下面这条命令里
>alice 用户名
>ssalg-gnikool 主机名
>/bin/bash 能够执行的命令
#提权到 root。>- h 参数有帮忙菜单（display gelp message and exit），也有在主机上运行命令的意思（run command on host）alice@looking-glass:/$ sudo -h ssalg-gnikool /bin/bash
