Timeout policy not enabled in Red Hat Enterprise Linux 7.2 kernel

The nfct timeout command is not supported in Red Hat Enterprise Linux 7.2. As a workaround, use the global timeout values available at /proc/sys/net/netfilter/nf_conntrack_*_timeout_* to set the timeout value.

Verification of signatures using the MD5 hash algorithm is disabled in Red Hat Enterprise Linux 7

It is not possible to connect to any Wi-Fi Protected Access (WPA) Enterprise Access Point (AP) that requires MD5-signed certificates. To work around this problem, copy the wpa_supplicant.service file from the /usr/lib/systemd/system/ directory to the /etc/systemd/system/ directory and add the following line to the Service section of the file:
Then run the systemctl daemon-reload command as root to reload the service file.


Note that MD5 certificates are highly insecure and Red Hat does not recommend using them.
