Here is a sample configuration file for the SSH client (ssh_config):
# SSH client configuration file
# Global settings
Host *
# Set default options for all hosts
ForwardAgent yes
ForwardX11 yes
PasswordAuthentication yes
PubkeyAuthentication yes
ServerAliveInterval 60
# Host-specific settings
Host example.com
# Set options for a specific host
User myusername
Port 22
IdentityFile ~/.ssh/id_rsa
Host anotherhost.com
# Set options for another host
User anotheruser
Port 2222
IdentityFile ~/.ssh/another_key
Host anotherhost
# Set options for another host
HostName dev.example.com
User anotheruser
Port 2222
IdentityFile ~/.ssh/another_key
# Add more host configurations as needed
You can save this configuration file as ~/.ssh/config on your Linux/Debian system. Make sure to replace example.com and anotherhost.com with the actual hostnames or IP addresses of the SSH servers you want to connect to. Also, update the User, Port, and IdentityFile options according to your specific setup.
