Networking
The following network related features and functionalities are deprecated in Oracle Linux 9.
Network Teams
The teamd service, and the libteam library, and support
for configuring network teams are deprecated in favor of network bonds. You should use
network bonds instead, which have similar functions as teams, and which would receive
enhancements and updates.
/etc/sysconfig/network-scripts File
Network configurations profiles used to be in ifcfg format and stored in the
/etc/sysconfig/network-scripts directory. This format is deprecated. In
Oracle Linux 9, new network configurations are stored in
/etc/NetworkManager/system-connections in keyfile format. This format works
with all the connection settings provided by NetworkManager.
However, information in the /etc/sysconfig/network-scripts remain
operative, and modifications to existing profiles continue to update the older
files.
iptables Framework
With the deprecation of the iptables framework, the
iptables backend and the direct interface are also
deprecated.
Therefore, the following packages are also deprecated:
-
iptables-devel -
iptables-libs -
iptables-nft -
iptables-nft-services -
iptables-utils
As an alternative to using direct interface, use the native features in
firewalld to configure the required rules.
PF_KEYv2 Kernel API
The PF_KEYv2 API is used to configure kernel IPsec implementation.
However, thie API isn't maintained upstream. Therefore, this API is deprecated. Instead,
use the netlink API as a replacement.
Network Manager nmcli Language Changes
connection.master, connection.slave-type, and
connection.autoconnect-slaves connection property names are
deprecated. They are retained for backward compatibility. However, consider using the
following replacement terms instead:
- Instead of
connection.master, useconnection.controller - Instead of
connection.slave-type, useconnection.port-type - Instead of
connection.autoconnect-slavesuseconnection.autoconnect-ports
