題目

Using a Secure Shell (SSH) is going to be pretty important. Can you ssh as ctf-player to titan.picoctf.net at port 51850 to get the flag? You'll also need the password 6abf4a82. If asked, accept the fingerprint with yes.
If your device doesn't have a shell, you can use: https://webshell.picoctf.org

解法

概念

就是簡單使用 ssh 連線過去就可以拿到 shell，而 ssh 的連線方法是 ssh <username>@<domain>，這題多了一個 port number 要輸入，就用 -p <port> 就可以了

執行結果如圖

得到 flag 為 picoCTF{s3cur3_c0nn3ct10n_65a7a106}
