Live update does not work when BIG-IP DNS is configured to use IPv6.


-- Unable to install latest updates to signatures. -- Unable to import user-defined signatures.


BIG-IP DNS uses IPv6.


If possible, use IPv4 for DNS. An alternative workaround could be to configure a working IPv4 address in the "/etc/hosts" file, by issuing the following command from the advanced shell (bash): echo " callhome.f5.net" >> /etc/hosts

Fix Information

Replaced deprecated gethostbyname which does not work well with IPv6 with getaddrinfo.
