Panic on execution

[yaniveliash]

panic: Can't run remote command: ssh: must specify HostKeyCallback

[katechun]

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

modify file easyssh.go:

config := &ssh.ClientConfig{
	User: ssh_conf.User,
	Auth: auths,
	HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {
		return nil
	},
}
