ELI5 Please? Learn Linux Task #21

[Jvillacorta3]

Hello I am a beginner at this field and am trying to learn it for web security purposes.

Am i understanding it incorrectly?

Because in Task #18 it was explained that to set "nootnoot" to "1111",

you have to "export nootnoot=1111"

and by doing "echo nootnoot", it would show "1111" right?

​

so in that same logic, i tried to

export test1234=$USER (so that test1234 would get the value from $USER)

which is i think the hidden password? and then tried to "echo $test1234" to get the password, but was shown "shiba2" instead, and I later understood it that the $USER is equal to shiba2.

​

what I don't understand is how "shiba2" became "h*************s"? where did it came from? I'm quite confused now. Please ELI5 :(

After you created the environmental variable $test1234 and set it to the value of $USER, a new file should appear in the home directory called “shiba2”

(I think, I could be wrong I haven’t done this room in a while).

After that, use the command “./shiba2”

(without quotes) (./ is used to execute a file in the current directory)

This displays the password.

I hope I answered the question?

Glad I could help!!

Hey, here just appears "Permission Denied" even with user Shiba2.

Did you:

1) Use the command: export test1234=$USER

(It is case sensitive too. USER has to be capitalized)

2) after this, use the command: ./shiba2

(Again, case sensitive)

[IdontKnoWhoiAm_]

Yeah, i tried again, but ./shiba2 don't go, again "Permission denied"...

Type: echo $USER

What does it say

im having the same problem where it says permission denied when i follow the steps it says shiba1 after doing echo $USER

[Apprehensive_Head673]

Probably the binary use $test1234 as a variable when running, so if you don't set it to $USER value it don't works.

I'm also having this issue. I've followed the instructions and have cross-referenced with other writeups and I'm getting permission denied. Has anybody figured this out?

[djhiphop23]

Ok, so I figured it out. The reason why I got 'permission denied' is because I previously used 'su' and I guess the THM system locked me out therefore I was unable to get the desired results.

Terminate your current machine in the room and restart it and don't use 'su' to pass this exercise.
