But warning! You can have IPv4 resolving or IPv6 resolving. Some software (e.g. exim) does IPv6 resolving first. Since libnss-myhostname sets up IPv6 resolving for the local hostname, which is usually not done in /etc/hosts (at least by default), settings done by libnss-myhostname come first in this case, so that libnss-myhostname can break things: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756224#114 libnss-myhostname should not be used (at least currently) when the user has a /etc/hosts file. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
