Package: 2ping Version: 2.0-1 Tags: ipv6 Hi Ryan,
setting TWOPINGD_RUN=yes in /etc/default/2ping only enables a listener on IPv4, not on IPv6: # lsof -p 8876 | fgrep IP 2ping 8876 nobody 4u IPv4 4022853 0t0 UDP *:15998 Tested with both, IPv6 addresses on eth0 (tested on Wheezy) as well as with a Teredo tunnel created by miredo (tested on Sid, where I wrote the report and from where are the lsof outputs), both times with libio-socket-inet6-perl being installed. Adding TWOPINGD_OPTS="-6" causes the listener to only listen on IPv6: # lsof -p 7012 | fgrep IP 2ping 7012 nobody 4u IPv6 4019791 0t0 UDP *:15998 The only possibility to run a 2ping listener on both, IPv4 and IPv6, at the same time seems to be to explicitly list IP addresses and to put the -6 option just between all IPv4 and all IPv6 addresses: TWOPINGD_OPTS="-I 192.168.1.129 -6 -I 2001:1620:f51:1:225:90ff:fe09:9c98" At least with Teredo tunnels, the option -I doesn't help much as the tunnel tends to get a new IP address on restart and the option explicitly needs an IP address and not a device name. The option -I is also less suitable if you want to enable IPv6 listeners on arbitrary machines by default. So it would be nice, if there would be a possibility to listen on all IPv4 and IPv6 interfaces and addresses without the need to list all IP addresses. Maybe add a "-4" option to listen on IPv4, so that one can set TWOPINGD_OPTS="-4 -6" in /etc/default/2ping. (Maybe a hook script in /etc/network/if-up.d/ to reload the list of all interfaces 2ping should listening to, would be a good idea, too.) -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (990, 'unstable'), (900, 'testing'), (899, 'testing-proposed-updates'), (600, 'stable'), (500, 'proposed-updates'), (200, 'experimental') Architecture: i386 (i686) Kernel: Linux 3.10-rc5-686-pae (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages 2ping depends on: ii perl 5.14.2-21 Versions of packages 2ping recommends: ii libio-socket-inet6-perl 2.69-2 ii perl-modules 5.14.2-21 Versions of packages 2ping suggests: ii libdigest-crc-perl 0.18-1+b1 ii perl [libdigest-sha-perl] 5.14.2-21 -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
