# WL#12720 Add support for network namespaces on setting up listening sockets

# Network namespaces is a feature of Linux.
# So, ignore this test on any platform except Linux.
--source include/linux.inc

# This test relies on the fact that environment was configured
# to support the network namespace. Namely, the network namespace named 'red'
# must be set up on every linux host involved into pushbuild infrastructure.
# The network interface in the namespace 'red' must be assigned IP address 10.0.2.1
# and routing between the IP address 10.0.2.1 from the network namespace 'red'
# and IP addresses from the root (default) network namespace must be configured.
# Until it be done on every linux host inside pushbuild infrastructure this
# test must be disabled.
