<!-- Kamailio Project uses GitHub Issues only for bugs in the code or feature requests. Please use this template only for bug reports. If you have questions about using Kamailio or related to its configuration file, ask on sr-users mailing list: * https://lists.kamailio.org/mailman3/postorius/lists/sr-users.lists.kamailio… If you have questions about developing extensions to Kamailio or its existing C code, ask on sr-dev mailing list: * https://lists.kamailio.org/mailman3/postorius/lists/sr-dev.lists.kamailio.o… Please try to fill this template as much as possible for any issue. It helps the developers to troubleshoot the issue. Note that an issue report may be closed automatically after about 2 months if there is no interest from developers or community users on pursuing it, being considered expired. In such case, it can be reopened by writing a comment that includes the token `/notexpired`. About two weeks before considered expired, the issue is marked with the label `stale`, trying to notify the submitter and everyone else that might be interested in it. To remove the label `stale`, write a comment that includes the token `/notstale`. Also, any comment postpone the `expire` timeline, being considered that there is interest in pursuing the issue. If there is no content to be filled in a section, the entire section can be removed. You can delete the comments from the template sections when filling. You can delete next line and everything above before submitting (it is a comment). --> ### Description When `auto_bind_ipv6` is enabled on a system without ipv6, kamailio starts, enumerates all interfaces but does not perform no listening at all. In addition, no errors are reported, see below from final part of boot log, no other infos are logged. While this can be worked around by putting that config value behind a definition and autodetection by an external script, should not it work and just start on ipv4 if ipv6 is not available? ### Troubleshooting #### Reproduction <!-- If the issue can be reproduced, describe how it can be done. --> Just start Kam as root, with no `listen` directives (to let it listen on all ipv4) and `auto_bind_ipv6` set to 1. #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` 0(1) DEBUG: <core> [core/socket_info.c:1764]: add_interfaces(): If: lo Fam: 2 Flg: 10049 Adr: 127.0.0.1 0(1) DEBUG: <core> [core/socket_info.c:1764]:
