panic: Failed to create fetcher instance: ssh: must specify HostKeyCallback

Was using with Amazon EC2 instances you get this thrown back at you. I have strict host checking enabled.

config file if needed

[database]
	[database.myfrom]
		host = "****"
		management_system = "mysql"
		name = "****"
		user = "****"
		password = "****"
        
	[database.myto]
		host = "****"
		management_system = "mysql"
		name = "****"
		user = "****"
		password = "****"

[ssh]
	[ssh.myfrom]
		host = "*ec2ipaddress*"
		port = "****"
		user = "****"
		key = "****"

	[ssh.myto]
		host = "*ec2ipaddress*"
		port = "****"
		user = "****"
		key = "****"

Trying to read trough your code to see if there's any way around this or maybe I can fix this myself, if anything comes up will report.

Seems like - if you edit your database.go file and add function

func HostKeyCallback(hostname string, remote net.Addr, key ssh.PublicKey) error {
	
	return nil
}

obviously have to put the contents that verify the hostname

and then in your "generateSSHSign" where you specify the "config" variable you also add a key of "HostKeyCallback" pointing to that function it should all work
