## 513 - 渗透测试 Rlogin

### 基本信息

In the past, **rlogin** was widely utilized for remote administration tasks. However, due to concerns regarding its security, it has largely been superseded by **slogin** and **ssh**. These newer methods provide enhanced security for remote connections.

**默认 port:** 513

```
PORT    STATE SERVICE
513/tcp open  login
```

### **Login**

```bash
## Install client
apt-get install rsh-client
```

You can use the following command to try to **login** to a remote host where **no password** is required for access. Try using **root** is as username:

```bash
rlogin <IP> -l <username>
```
