To configure OpenSSH to listen on an IPv6 address in Linux or Unix, you will need to edit the sshd_config
configuration file.
The sshd_config
file is typically located in the /etc/ssh
directory. To edit the file, you will need to use a text editor, such as vi
or nano
.
To configure OpenSSH to listen on an IPv6 address, locate the following line in the sshd_config
file:
#ListenAddress 0.0.0.0Source:tual.wwwturi.com
Remove the #
character at the beginning of the line to uncomment it, and then add the IPv6 address you want OpenSSH to listen on. For example:
ListenAddress [::]:22
This will configure OpenSSH to listen on all available IPv6 addresses on port 22
.
You can also specify a specific IPv6 address to listen on. For example:
ListenAddress [2001:db8::1]:22
This will configure OpenSSH to listen on the IPv6 address 2001:db8::1
on port 22
.
Save the changes to the sshd_config
file and exit the text editor. Then, restart the OpenSSH server to apply the changes:
service ssh restart
