Dear Maintainer,

There are multiple patches in debian finger to make it work on ipv6.
Unfortunately, if I install fingerd, it's not listening on ipv6, only on ipv4.

This is because the configuration in /etc/inetd.conf is incorrect;

if I change 'tcp' to 'tcp6' on this line:

fingerentry="finger             stream  tcp     nowait  nobody  /usr/sbin/tcpd  /usr/sbin/in.fingerd"


fingerentry="finger             stream  tcp6    nowait  nobody  /usr/sbin/tcpd  /usr/sbin/in.fingerd"

everything works as expected, fingerd is now listening on both ipv4 and
ipv6.


Please see this patch:
