I have IPv6 disabled and nscd disabled. I see the same timeouts with other network programs, in particular no difference between firefox and e.g. curl and wget. This makes the surfing experience with 11.3 very cumbersome. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
