Distcc does not seems to be able to sometimes handle ipv6-addresses. This manifests itself by choking on parsing of hosts-file resulting in distcc doing the compile locally. Reproducible: Always Steps to Reproduce: 1. Emerge distcc-2.18.3-r12 2. Enable zeroconf 3. run distcc --show-hosts Actual Results: $ distcc --show-hosts distcc[31262] (dcc_parse_tcp_host) ERROR: invalid tcp port specification in ":280:5fff:fed7:6814:3632/8 " distcc[31262] (dcc_zeroconf_add_hosts) CRITICAL! failed to parse host file. distcc[31262] (dcc_show_hosts) CRITICAL! Failed to get host list Expected Results: (same output as this) $ cat .distcc/zeroconf/hosts 192.168.0.106:3632/8 192.168.0.1:3632/4 fe80::280:5fff:fed7:6814:3632/8 For a reason distcc chokes on this adress for some reason even if others are showing up. On the other hand: should distcc pick up local link addresses any way? One other intresting point is that on my other system this is not a problem, as it only shows my ipv4-adresses. distcc is compiled with ipv6-support on both computers.

the diffrence between the system seemed in the end being ipv6 being enabled for avahi on the non-working and disable on the working. So distcc seems to not work (no matter if it is compiled with or without ipv6-support) with the ipv6 adresses provided by avahi.
I can confirm the same behavior in distcc-2.18.3-r13 with avahi-0.6.22-r1: namely distcc fails to parse ipv6 addresses. I agree also that if avahi has ipv6 enabled, distcc chokes whether or not the distcc's ipv6 flag is set or not. The workaround is indeed to use -ipv6 with avahi. In that case distcc never sees any ipv6 addresses, so never chokes. Arch: i686.
hmm, /etc/distcc/hosts, '--listen' and '--allow' also don't work with ipv6. I think that distcc does not support ipv6 yet. '--enable-rfc2553' is *not* for ipv6!!!
