After reading the posts regarding custom portal webpages, this has lead me to two more questions:
1. How do you reference an image file for the custom page? I have tried a relative path (./image.gif), absolute path (/root/kerbynet.cgi/template/image.gif) and simply /image.gif and none have worked.
2. Is it possible to modify the content or eliminate the page — I think it’s generated dynamically (?) by zscp — so that you do not have to have the tiny window open all of the time to sustain a connection?
