How to automate tasks to run at intervals on Linux servers?

Use ssh to connect to this server (given ssh username, hostname and password).

Solution

$ ssh [e-mail]

picoplayer@challenge:~$ cat /etc/crontab
# picoCTF{Sch3DUL7NG_T45K3_L1NUX_7754e199}

Flag

And there we have are first, fairly easy flag picoCTF{Sch3DUL7NG_T45K3_L1NUX_7754e199}
