Usage:
  assh connect [flags]

Examples:
Argument is a host.

Flags:
      --dry-run      Only show how assh would connect but don't actually do it
  -h, --help         help for connect
      --no-rewrite   Do not automatically rewrite outdated configuration
  -p, --port int     SSH destination port

failed to dial: dial tcp 0.0.0.101:22: connect: no route to host
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535

why the hostname is # HostName: 192.168.2.101 in generated ~/.ssh/config, not hostname 192.168.2.101, Can I customize the template before building config?
