Dear all, Thanks for those who responded. It seems that one may use the tools xisp (available as a debian package), ezppp (http://www.serv.net/~cameron/ezppp/index.html) or Linuxconf for easy switching of ISP. But does Linuxconf work in harmony with Debian? Regards, -- Billy C.-M. Chow <cmchow@se.cuhk.edu.hk> Department of Systems Engineering The Chinese University of Hong Kong
