Re: Socket problems

[Tom Van den Panhuyzen <tomvdp@xxxxxxxxx>]

You are absolutely sure the hub is not the problem ?
I mean:
- Ethereal does not see packets going to 5001;
- your app (bound to a local IP) does not get them.

It looks like there just not there.

A tool that helped me during debug sessions of xpllib is cports.
