9.3.5 Hotplug Events Handled by the udev
Daemon
Hotplug events are now completely handled by the udev daemon (udevd). The event
multiplexer system in /etc/hotplug.d and /etc/dev.d is no longer used. Instead,
udevd calls all hotplug helper tools directly according to its rules. Udev rules and
helper tools are provided by udev and various other packages.
9.3.6 Firewall Activation During the
Installation
To increase security, the enclosed firewall solution SuSEFirewall2 is activated at the
end of the installation in the proposal dialog. This means that all ports are closed initially
and can be opened in the proposal dialog if necessary. By default, you cannot log in
from remote systems. It also interferes with network browsing and multicast applications,
such as SLP, Samba ("Network Neighborhood"), and some games. You can fine-tune
the firewall settings using YaST.
If network access is required during the installation or configuration of a service, the
respective YaST module opens the needed TCP and UDP ports of all internal and ex-
ternal interfaces. If this is not desired, close the ports in the YaST module or specify
other detailed firewall settings.
9.3.7 KDE and IPv6 Support
By default, IPv6 support is not enabled for KDE. You can enable it using the /etc/
sysconfig editor of YaST. The reason for disabling this feature is that IPv6 addresses
are not properly supported by all Internet service providers and, as a consequence, this
would lead to error messages while browsing the Web and delays while displaying Web
pages.
9.3.8 Online Update and Delta Packages
Online Update now supports a special kind of RPM package that only stores the binary
difference from a given base package. This technique significantly reduces the package
