[SR-Users] driver error: Can't connect to MySQL server with kamailio 5.3.x and mysql-config-groups

Wed Oct 23 18:16:34 CEST 2019

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

    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.

Cheers Karsten
