Free and open source DNS server for UNIX systems MyDNS is a free DNS server for UNIX. MyDNS was implemented from scratch and is designed to serve records directly from an SQL database (currently either MySQL or PostgreSQL).Its primary objectives are security, interoperability, stability, and speed, though not necessarily in that order. Requirements: · MySQL What's New in This Release: · Implemented RFC 2136 (DNS UPDATE). See the manual for usage instructions. · Fixed minor bug in admin.php where if db_get_settings() failed, it might display an error message without consistent formatting. · Added two additional fields to the --verbose query log. The opcode of the query (QUERY or UPDATE), and a quoted field containing a description of the UPDATE performed, if the opcode was UPDATE. · Updated contrib/stats.php to handle new log fields. · Fixed bug in --dump-config -- if present, fields without default values ("no-listen", "soa-where", "rr-where", and "recursive") were not being dumped. · Made --dump-config dump ALL possible configuration options, even if no value was originally specified. As such, MyDNS will no longer warn the user when a config option doesn't have a value. It will be silently ignored. · Including after a suggestion by Christian Tschenett, to help things out on 64-bit platforms like OSX. If this creates problems on your platform, please let me know. · Modified admin.php to allow a backslash in the 'mbox' field, immediately preceding a dot. This is used in DNS to indicate the presence of a dot in the username part of the administrator's email address. There was an additional bug report from Andreas Grip that MyDNS was replying with the slashes doubled up in this case, but it appears to be a problem with the "dig" program, not MyDNS. · Fixed bug with "rr-where" clause -- conf.c was using "soa-where" instead. David Darville first reported this bug. Michael Gile submitted it two minutes later, with a patch. · Added "create_domain.pl" to the contrib/ directory. Thanks to Gerard de Brieder for this script. See contrib/README for more information. · Fixed bug in src/lib/rr.c (mydns_rr_load) that caused a segfault if origin was NULL (it was designed to allow NULL, but this version is the first to ever call it in that way). · Added support for NAPTR (RFC 2915) records. Users with existing MyDNS databases will need to alter their tables to allow "NAPTR" in the "type" column if they want to use NAPTR. · Renamed library functions mydns_parse_rr() and mydns_parse_soa() to mydns_rr_parse() and mydns_soa_parse(), for consistency. · Library functions mydns_rr_dup() and mydns_soa_dup() now fail (terminating the program) if out of memory. · Moved routines that parse data for individual RR types (RP, SRV, and NAPTR) into individual functions from mydns_rr_parse for clarity. · Fixed bug where AXFR might transmit incorrect information if a FQDN is used in the 'name' field. · Fixed AXFR bug with ALIAS enabled. Thanks to Sven Wegener for the patch. · Created file "README.mysql" to address various problems common while compiling with MySQL support. · Fixed "use of cast expressions as lvalues is deprecated" warning (caused compilation abort with --enable-debug). · Added hostname to beginning of SIGUSR1 status output. · Renamed "update" column in the soa table to "update_acl"; how could I be so stupid as to name a column "update"?! · Fixed a critical denial-of-service vulnerability.
