a service running on your computer on that port.<br> <br> I always use port numbers at the upper end of the range. <br> <br> Looking at the above page port 1234 is assigned by IANA to the
infoseek search agent and unofficially used by the VNC client. <br> <br> Cheers,<br> <br> Herbert<br> <br> <div class="x_615022236moz-cite-prefix">Am 15.10.2021 um 14:19 schrieb Marcel
