When I activate the ppp interface, it takes much more time than with FC1. When I had FC1 running, the log almost immediately showed the lines with the local and remote IP addresses and DNS' addresses. Now, after the line "ppp <- /dev/pts... " or whatever, it takes ten or more seconds to see those addresses. After that moment, the connection itself is very slow. As I say in the answer to Andy Green, some traceroute and ping command show that DNS is not the issue here: name are resolved immediately. Traceroute starts printing "*" after several lines which appears quite rapidly, and keeps on this way for many many seconds, I never had that much patience to wait for it to stop. > I think you _may_ be hitting the problem with mozilla and IPV6, which is > turned on by default in FC2.

Must I recompile the kernel, or have I just to echo something somewhere in /proc? Many thanks. > Christoph > -- Andrea Giuliano, Ph. D.
