Package: bind9-dnsutils Version: 1:9.18.0-2 Querying DNS for a particular record type should look roughly like this:
| # nslookup -type=SRV localhost | Server: 172.27.0.3 | Address: 172.27.0.3#53 | | *** Can't find localhost: No answer That's the case with 1:9.16.27-1~deb11u1 in Debian stable, or 1:9.16.15-1ubuntu1.2 in Ubuntu 21.10, or bind-utils-9.16.27-1.fc35.x86_64 in Fedora 35. However, in Debian testing is now a wall of debug logging, which makes the result really hard to see: | # nslookup -type=SRV localhost | main parsing localhost | addlookup() | make_empty_lookup() |
