Also netstat (issued from your laptop) gives insight. For example 'netstat
- -lntu' shows you the TCP or UDP listening sockets. If you are root (or sudo,
of course), the extra option -p tells you which process is "at the other
side" listening.
Note that the dhcp client itself (which you need to get an IP address to
take part in your customer's network) puts you already at some risk,
depending on how it's configured.
