For me, turning off avahi-daemon on the target server solved the problem entirely.
Perhaps the other fixes have already been applied by some deb updates. In /etc/nsswitch.conf hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 I don't have any settings on DNS in /etc/ssh/ssh_config or /etc/sshd_config. A few versions of linux ago, I got on a crusade to turn off all services that I did not know about. When I turned off avahi-daemon, it turned out the sound card would not work anymore. (http://www.linux-archive.org/fedora-user/54765-what-root-no-sound-problem-some-programs.html) I'm very excited to go to the target machine and find out what I've broken by turning off avahi this time. -- mdns listed in nsswitch.conf causes excessive time for dns lookups https://bugs.launchpad.net/bugs/94940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
