As an AI language model, I'm sorry to inform you that the error message "telnet: connect to address 192.168.182.131: Connection refused" indicates that the connection was refused by the target host or the firewall. It could be due to a variety of reasons, including incorrect IP address, port number, or network configuration. To resolve the issue, you need to check the target host's firewall settings and ensure that the port you are trying to connect to is open and accessible.

回答: 当使用telnet命令连接到地址192.168.7.10时,出现"Connection refused"的错误。这通常表示目标主机拒绝了连接请求。可能的原因之一是目标主机上没有运行任何服务器进程,或者服务器进程正在监听的端口没有打开。根据提供的引用和引用,当一个TCP连接关闭时,操作系统可能会将连接状态保持一段时间,这个状态被称为TIME_WAIT或CLOSE_WAIT。在这段时间内,操作系统会阻止其他进程使用相同的端口。因此,如果之前有一个服务器进程在地址192.168.7.10上监听了某个端口,并且该连接仍处于TIME_WAIT状态,那么尝试在该地址上使用telnet连接可能会导致"Address already in use"的错误。另外,引用提到了可能涉及的机器,但与telnet连接被拒绝的问题无直接关联。
所以,当telnet连接到地址192.168.7.10时出现"Connection refused"的错误,可能是因为目标主机上没有运行服务器进程或者目标主机正在监听的端口没有打开。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

telnet: connect to address 192.168.20.98: Connection refused
这个错误信息通常出现在以下几种情况下:
1. 目标主机没有开放对应的端口,导致连接被拒绝;
2. 目标主机的防火墙拦截了连接请求;
3. 目标主机的网络服务没有启动或异常。
因此,你需要检查以下几个方面:
1. 确认目标主机的 IP 地址和端口号是否正确;
2. 确认目标主机是否开放了对应的端口;
3. 确认目标主机的防火墙是否允许该端口的入站连接;
4. 确认目标主机的网络服务是否已经启动。
如果以上都没有问题,可以使用其他工具(如 nmap)来扫描目标主机的端口状态,以便进一步排查问题。
