[Bug 871] request for idn (intl domain names) support
http://bugzilla.mindrot.org/show_bug.cgi?id=871 Summary: request for idn (intl domain names) support Product: Portable OpenSSH Version: 3.8.1p1 Platform: All OS/Version: Linux Status: NEW Severity: enhancement Priority: P2 Component: Miscellaneous AssignedTo: openssh-bugs at mindrot.org ReportedBy: egmont at uhulinux.hu This entry is meant to be a feature request for handling host names with accents in them. I see at least two ways of possible technical approaches: either use the libidn library, or use the AI_IDN and AI_CANONIDN flags or getaddrinfo() which are available at least in glibc cvs and some brand new distros e.g. Fedora 2. I send a quick & dirty & should-not-be-applied-as-it-is patch which is kind of a case study that "okay it's really not that hard to make it work". It basically works, however, there are some bugs/notes which might require some attention. - it sure needs some autoconf'isation to autodetect whether AI_IDN and AI_CANONIDN are available. - setlocale() is required, since getaddrinfo() assumes the accented host names are encoded in the current locale's charset. - Currently the host name is put in .ssh/known_hosts exactly as the same byte sequence as it was given to ssh. So if I use a latin1 terminal to connect to an accented host, and later I use an utf-8 terminal then it's not recognized to be the same host, actually, it is added once again to known_hosts with a different encoding. It's even possible theoretically that two different hosts from two terminals using different encodings conflict each other in this file. So I'd recomment to always use utf-8 when storing host names in files, regardless of the current locale. - When I have latinX terminal, everything is fine now. However, in UTF-8 terminal I see this: $ ssh ?x The authenticity of host '?x' (...)' can't be established. ^^ this is okay RSA key fingerprint is ... Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '\303\263x' (RSA) to the list of known hosts. ^^^^^^^^ this is not okay ... ... Connection to ?x closed. ^^ okay again So that \ooo escaping should be removed. I hope you don't find it a silly request. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
