Background Intelligent Transfer Service
Transfers files in the background using idle network bandwidth. If the service is disabled, then any applications that depend on BITS, such as Windows Update or MSN Explorer, will be unable to automatically download programs and other information.
Remote Desktop Connection Broker
Enables a user connection request to be routed to the appropriate Remote Desktop Session Host server in a cluster. If this service is stopped, connection requests will be routed to the first available server.
Disable Support for RPC IPv6
RPC services for NFSv4 try to load transport modules for
'udp6' and 'tcp6' by default, even if IPv6 has been disabled in
'/etc/modprobe.d'. To prevent RPC services such as 'rpc.mountd'
from attempting to start IPv6 network listeners, remove or comment out the
following two lines in '/etc/netconfig':
udp6 tpi_clts v inet6 udp - -
tcp6 ...
Manually Assign Global IPv6 Address
To manually assign an IP address for an interface, edit the
file '/etc/sysconfig/network-scripts/ifcfg-interface'. Add or correct the
following line (substituting the correct IPv6 address):
'IPV6ADDR=2001:0DB8::ABCD/64'
Manually assigning an IP address is preferable to accepting one from routers or
from the network otherwise. The example address here is an IPv6 ...
Use Privacy Extensions for Address
To introduce randomness into the automatic generation of IPv6
addresses, add or correct the following line in
'/etc/sysconfig/network-scripts/ifcfg-interface':
'IPV6_PRIVACY=rfc3041'
Automatically-generated IPv6 addresses are based on the underlying hardware
(e.g. Ethernet) address, and so it becomes possible to track a piece of
hardware over its lifetime using ...
Manually Assign IPv6 Router Address
Edit the file
'/etc/sysconfig/network-scripts/ifcfg-interface', and add or correct
the following line (substituting your gateway IP as appropriate):
'IPV6_DEFAULTGW=2001:0DB8::0001'
Router addresses should be manually set and not accepted via any
auto-configuration or router advertisement.
Enable rsyslog Service
The 'rsyslog' service provides syslog-style logging by default on RHEL 7.
The 'rsyslog' service can be enabled with the following command:
'$ sudo systemctl enable rsyslog'
Configure Logwatch HostLimit Line
On a central logserver, you want Logwatch to summarize all syslog entries, including those which did not originate
on the logserver itself. The 'HostLimit' setting tells Logwatch to report on all hosts, not just the one on which it
is running.
' HostLimit = no '
