Package: bind9-host Version: 1:9.11.5.P4+dfsg-5.1+deb10u1 Severity: normal Dear Maintainer,
Since buster, it seems that host insists in outputing a decoded version of IDN domain names, and if the locale does not support it, it fails: schaefer@virtual:~$ env LC_CTYPE=C host xn--linux-neuchtel-lhb.ch host: Cannot represent 'xn--linux-neuchtel-lhb.ch.' in the current locale (string encoding error), use +noidnout or a different locale However, the suggested option +nodinout does not work. Then the manpage says: > IDN SUPPORT > If host has been built with IDN (internationalized domain name) > support, it can accept and display non-ASCII domain names. host > appropriately converts character encoding of domain > name before sending a request to DNS server or displaying a reply from > the server. If you'd like to turn off the IDN support for some reason, > defines the IDN_DISABLE environment > variable. The IDN support is disabled if the variable is set when host > runs. However: schaefer@virtual:~$ env LC_CTYPE=C IDN_DISABLE=1 host xn--linux-neuchtel-lhb.ch localhost host: Cannot represent 'xn--linux-neuchtel-lhb.ch.' in the current locale (string encoding error), use +noidnout or a different locale the only partial workaround I know is to change the locale, e.g.: schaefer@virtual:~$ env LC_CTYPE=fr_CH.iso-8859-1 IDN_DISABLE=1 host xn--linux-neuchtel-lhb.ch localhost But then you don't get the xn-- but you get the diacrictic version in the specified locale: linux-neuchâtel.ch has address 46.140.72.222 it would be nice to have a working way of disabling this new host behaviour. Have a nice day. -- System Information: Debian Release: 10.4 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-9-amd64 (SMP w/8 CPU cores) Locale: LANG=C, LC_CTYPE=fr_CH.iso-8859-1 (charmap=ISO-8859-1), LANGUAGE=C (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages bind9-host depends on: ii libbind9-161 1:9.11.5.P4+dfsg-5.1+deb10u1 ii libc6 2.28-10 ii libcap2 1:2.25-2 ii libcom-err2 1.44.5-1+deb10u3 ii libdns1104 1:9.11.5.P4+dfsg-5.1+deb10u1 ii libfstrm0 0.4.0-1 ii libgeoip1 1.6.12-1 ii libgssapi-krb5-2 1.17-3 ii libidn2-0 2.0.5-1+deb10u1 ii libisc1100 1:9.11.5.P4+dfsg-5.1+deb10u1 ii libisccfg163 1:9.11.5.P4+dfsg-5.1+deb10u1 ii libjson-c3 0.12.1+ds-2 ii libk5crypto3 1.17-3 ii libkrb5-3 1.17-3 ii liblmdb0 0.9.22-1 ii liblwres161 1:9.11.5.P4+dfsg-5.1+deb10u1 ii libprotobuf-c1 1.3.1-1+b1 ii libssl1.1 1.1.1d-0+deb10u3 ii libxml2 2.9.4+dfsg1-7+b3 bind9-host recommends no packages. bind9-host suggests no packages. -- no debconf information
