http://epub.iaea.org/fusion via PPP gives only some 100 chars, then stalls. EXCEPT, if it happens that local and remote IP addresses are almost the same (which almost never happens) Never a problem with Windows. lynx behaves the same as Netscape. ALL other web sites under RH with this PPP connection work fine.
we can't duplicate the problem here. It would seem to be an obscure problem with your setup. If you can duplicate the behaviour on another Red Hat Linux box, please reopen the bug.
