Bug ID 945789: Live update cannot resolve hostname if IPv6 is configured.

Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP ASM(all modules)

Fixed In:
16.1.0, 15.1.4.1

Opened: Sep 16, 2020

Severity: 3-Major

Symptoms

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

Impact

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

Conditions

BIG-IP DNS uses IPv6.

Workaround

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 "165.160.15.20 callhome.f5.net" >> /etc/hosts

Fix Information

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