We get a file called client.
client: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=bcb9d17215725749cf2ce0ee9ef5df3c98ba8f00, for GNU/Linux 4.4.0, stripped
When running it locally would only connect back to the port I gave it and just write back to me whatever I typed but in reverse.
When running it remotely I could only get.
Ran it with strace to see more of what it is doing and I got the flag.
