I've also spent time to reproduce this and despite my attempt to disable localhost IPv6 resolution [0], i already encountered issues for echosrv on ::1. You can also try to replace any occurrence of `localhost` on t file by 127.0.0.1. If the testsuite cause trouble, i'll disable IPv6 completely even on loopback (i didn't like the idea at first glance because want to keep the testsuite as close as upstream ship it). Then, any other special configurations in /etc/gai.conf ? [0]: https://anonscm.debian.org/cgit/collab-maint/sslh.git/tree/debian/patches/ftbfs_localhost.diff -- Guillaume Delacour
