ssh端口开放,却无法连接

发表于

在使用nmap扫描目标主机时:

nmap –osscan-guess www.minzhuokj.com
Starting Nmap 7.91 ( https://nmap.org ) at 2020-11-26 19:44 ?D1ú±ê×?ê±??
Nmap scan report for www.minzhuokj.com (39.96.251.199)
Host is up (0.025s latency).

PORT STATE SERVICE
1/tcp open tcpmux
3/tcp open compressnet
4/tcp open unknown
6/tcp open unknown
7/tcp open echo
9/tcp open discard
13/tcp open daytime
17/tcp open qotd
19/tcp open chargen
20/tcp open ftp-data
21/tcp open ftp
22/tcp open ssh
23/tcp open telnet
24/tcp open priv-mail
25/tcp open smtp
26/tcp open rsftp

发现 ssh 的 22 号端口开放, 于是尝试连接:

ssh.exe 39.96.251.199
ssh_exchange_identification: read: Connection reset

正常情况应该是提示输入用户名密码.

尝试获取更多详细信息:

ssh.exe 39.96.251.199 -v

百度以下, 你就知道, 解决方法总结如下:

  • 在服务端修改 ssh 配置
