I'm having nearly the same problem: Hard drive installation of Knoppix 3.2 with an ISP ("FreeISP") that connects via KPPP and allows me to ping the host, but which the browsers can't use (trying any Internet link instantly returns "Could not find www.xyz .com."). This is the case whether I'm root or user, which suggests that this isn't a permissions or group membership problem for resolv.conf or another important file somewhere. FreeISP works fine with the same KPPP settings in Mandrake 9.0 on the same computer, so it doesn't seem like a hardware problem.

Here's a twist, though -- I have another ISP ("SchoolISP") that does yield a successful connection! I'm hoping that the difference between the two ISP accounts provides some clues. FreeISP works in Mandrake with KPPP account defaults -- all I need to do is provide username, password, and a couple of DNS IP addresses provided by FreeISP. SchoolISP also works, in Mandrake and Knoppix, with KPPP defaults, with me providing only username, password, and a login script.

I've found several forum threads on the "connect, ping, but not browse" problem, and maybe they'll help Zzymdaexi:

"Modem Connects but No Internet"

"No Internet after HD Installation Problem"

"Suddenly Can't Connect"

"Can Ping Router but No Internet"

Unfortunately, none of them seems to have really nailed down what's going on. I seem to be the only one who's experiencing the problem for one ISP but not with another. Does anyone smarter about ppp (or who simply solved this problem with good old dumb luck) have any suggestions? Thanks!
