Public bug reported:
Hi,
We have found that on Ubuntu jammy the command "host non-existent-host-
name" hangs for ever, while it was working with Ubuntu impish. We tested
that under Docker:
> cat Dockerfile
ARG UBUNTU_VERSION
FROM ubuntu:${UBUNTU_VERSION}
RUN apt-get update && apt-get install -y dnsutils
> docker run -t -i --rm $(docker build --quiet --build-arg
> UBUNTU_VERSION=impish .) host -v non-existent-host-name
Trying "non-existent-host-name.rnd.amadeus.net"
Trying "non-existent-host-name"
Host non-existent-host-name not found: 2(SERVFAIL)
Received 40 bytes from 10.64.112.201#53 in 0 ms
> docker run -t -i --rm $(docker build --quiet --build-arg UBUNTU_VERSION=jammy
> .) host -v non-existent-host-name
Trying "non-existent-host-name.rnd.amadeus.net"
Trying "non-existent-host-name"
This hangs for ever here.
Quickly looking at the latest bind9 issues, I have found this:
https://gitlab.isc.org/isc-projects/bind9/-/issues/3145 which mentions this
pull request: https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/5954
which is still being discussed. It may (or may not, I don't know !) fix this
issue.
Cheers,
Romain
