I use the config-feature of my.cnf config-group names within the kamailio.cfg I can start my kamailio 5.3.x installation with "normal username:password@host" definitions for DBURL.

Hi Daniel, i create an Logfile with debug=3 on startup here: https://gist.github.com/khorsmann/91642daaa3715c59624cd5272bc3398a#file-log… 0(29174) DEBUG: db_mysql [km_my_con.c:108]: db_mysql_new_connection(): opening connection: mysql://xxxx:xxxx@kamailio/kamailio I dont know where kamailio though that there is an "hostname" kamailio that holds the mysqldb/kamailio. I want to use groups in the future - cos i auto-generate mysql-passwords with / for example and that is possible in groups, but i dunno how in normal defines. Cheers Karsten Am Di., 22.

Hello, if you set debug=3, do you see any other log message that can give hints about the error? I do not recall any change in using mysql conf groups, but there were some changes in supporting usernames with domains and few other updates that could have affected indirectly this part.

Hi Sergey, i set in my /etc/hosts an host entry names kamailio to see more. i tried that and i saw that the process kamailio is trying to reach "host: kamailio" with user=kamailio schemata=kamailio and password=kamailio on the wire. That seems to be the "defaults" if no values is found. I thing that the IPv6 Patch Idea from Daniel is more the root-cause [] is essential in ipv6 and its an pointer for DBURL/mysql-groups.

Could you record network traffic into PCAP like tcpdump -ni any host ${mysql_server_ip} -s 0 -w /tmp/mysql.pcap then sent.Will try look into network traffic. On Tue, Oct 22, 2019 at 5:39 PM Karsten Horsmann <khorsmann(a)gmail.com> wrote:

Hi Daniel, you mean this commit (see below). Maybe Alexey Vasilyev can told us something to that change? How can i use mysql-groups in the [] notation? Like: #!define DBURL "mysql://[kamailio]/kamailio" https://kamailio.org/docs/modules/5.3.x/modules/db_mysql.html#idm140 AFAIK this change splits [ and ] to ipv6 Host and sets ST_HOST6 and commit a7588f382605991bef4499de8c89b10a9468c8cf Author: Alexey Vasilyev <alexei.vasilyev(a)gmail.com> Date: Wed Sep 4 13:47:23 2019 +0300 db_mysql: database URL supports IPv6 address as hostname - changed parsing of db_url to accept IPv6 address for hostname Any help would be appreciated.

Hello, it could be that a patch to support ipv6 in the db url is conflicting with the syntax for the group name, because both seem to use [ ] . Iirc, such a commit was not long time ago. I will have to look at the code for mysql conf group to see what exactly it expects, not sure I got time for it today, though, maybe others can check quicker.
