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:
Environment=OPENSSL_ENABLE_MD5_VERIFY=1
Then run the
systemctl daemon-reload
command as root to reload the service file.
Important
Note that MD5 certificates are highly insecure and Red Hat does not recommend using them.
