Then it should be documented that nscd behaves poorly on this service. > I suspect, nscd has no notion of AF_UNSPEC, AF_INET, AF_INET6 and instead it > operates on more generic level. I can see several occurrences of AF_INET and AF_INET6 in several nscd source files, but no AF_UNSPEC except in a test file. Perhaps it is designed to handle AF_INET and AF_INET6 specifically but caches AF_UNSPEC as a generic entry by mistake. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
