When promoting a package, or doing another action that results in a notification email, I’m receiving error messages like this in my Output Log:
E03020134: send-mail: warning: inet_protocols: IPv6 support is disabled: Address family not supported by protocol.
E03020134: send-mail: warning: inet_protocols: configuring for IPv4 support only.
CA Harvest SCM 12.5 and 12.6 on a Linux or Unix platform
The messages indicate that IPV6 has not yet been enabled on the Linux broker machine.
You will need to turn on IPV6 in the kernel. Check this article for more information: http://unix.stackexchange.com/questions/64414/ipv6-support-is-disabled-warnings. The article also explains how you can turn off the warning messages instead if that is your preference.
For each process such as a promote or demote that would normally result in a notification email there’s a pre-link or post-link Notification UDP attached to the process. in the Harvest SCM Administrator Tool you’ll find these individually defined in every project and state where these processes are found. On the Notify Properties dialog, the "Mail Utility" field will identify which application is being used to send emails. If the field starts with "hsmtp", the Harvest SMTP utility is being used to send the emails (more information on HSMTP can be found in the CA Harvest SCM Administrator Guide). If you are seeing warning messages like those listed in the problem description above you will most likely find "mailx" in the "Mail Utility" field instead. Mailx is a Unix/Linux utility program for sending and receiving email messages. More information on Mailx can be found in the documentation for your specific operating system.
