Package: sane-utils
Version: 1.0.15-10
Severity: important
First thing saned tries to do is bind to port 6566 on local interfaces.
If IPv4 and IPv6 are both active though, the 'v6 is done first, which
blocks the address on 'v4, so the latter bind fails...
An strace of it failing:
socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 3
setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(3, {sa_family=AF_INET6, sin6_port=htons(6566), inet_pton(AF_INET6, "::",
&sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0
listen(3, 1) = 0
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 4
setsockopt(4, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(4, {sa_family=AF_INET, sin_port=htons(6566),
sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EADDRINUSE (Address already in use)
If before running saned, you
echo 1 >/proc/sys/net/ipv6/bindv6only
This causes the 'v4 port to be free, so the latter bind succeeds as
well.
