Package: ffproxy
Version: 1.6-3
Kernel version: 2.6.24-rc2
Linux doesn't allow the same port to be bound with IPv4 and IPv6
unless /proc/sys/net/ipv6/bindv6only is one -- binding to the wildcard
address on IPv6 will yield IPv4 connexions as well -- remote addresses
will be in IPv6-mapped format.
Therefore trying to use ffproxy and sking it to accept both ipv4 and
ipv6 connections doesn't work. You get a really strange error message
in /var/log/syslog (btw, stracing shows an attempt to write the
actual `address in use' message to closed FD 2)
Log message:
FFPROXY(master)[5266]: could not bind to IPv6, possibly
because of Linux's ``feature'' to bind to IPv4 also. Try -b or binding
to specific IPv6 address via -C if you're using IPv6 with
Linux 2.4 Error message, terminating
