Xiaobian to share with you the use of linux ssh-keyscan command to collect the ssh public key of the host, I hope you read this article after the harvest, let us discuss it together!

The ssh-keyscan command is a utility that collects a large number of host public keys. Its purpose is to create and validate the "ssh_known_hosts" file.

The ssh-keyscan command only supports ssh protocol version 1 and cannot be used in ssh protocol version 2.

Syntax format: ssh-keyscan [parameters]

Common parameters:

-4 Force IPv4 addresses-6 Force IPv6 addresses-f Read "address list, name list" from specified file Pair-p Specify port to connect to remote host-T Specify timeout for connection attempt-t Specify key type to create-v Information mode, print debug information

Reference Example

Collect the host ssh public key and output debug information:

[root@linuxcool ~]# ssh-keyscan -v 202.120.240.65

Display RSA host key for host 192.168.0.2:

[root@linuxcool ~]# ssh-keyscan 192.168.0.2

DSA host key for host 192.168.0.2 is displayed:

[root@linuxcool ~]# ssh-keyscan -t dsa 192.168.0.2

Print debugging information:

[root@linuxcool ~]# ssh-keyscan -v

Mandatory IPv4 addresses:

[root@linuxcool ~]# ssh-keyscan -4 After reading this article, I believe you have a certain understanding of using the linux ssh-keyscan command to collect the ssh public key of the host.
