For example, this can be the case in bubblewrap or Debian pbuilder after unsharing the network namespace: bwrap \ --bind / / \ --dev-bind /dev /dev \ --bind /dev/shm /dev/shm \ --bind /dev/pts /dev/pts \ --unshare-net \ ${builddir}/test/test-loopback --tap ... ok 1 /connect/tcp # SKIP Name resolution does not work here: getaddrinfo("127.0.0.1", "0", {flags=ADDRCONFIG, family=INET, socktype=STREAM, protocol=TCP}): Name or service not known On some systems this can be circumvented by using nss_wrapper from <https://cwrap.org/nss_wrapper.html >: cat > hosts <<EOF 127.0.0.1 localhost EOF bwrap \ ... \ env \ LD_PRELOAD=libnss_wrapper.so \ NSS_WRAPPER_HOSTS=$(pwd)/hosts \ ${builddir}/test/test-loopback --tap ... # listening at tcp:host=127.0.0.1,port=39219,family=ipv4,guid=... but for systems where that does't work, we should be prepared to skip the affected tests.
