[Bug 561475] [NEW] when sysctl net.ipv6.bindv6only=1, xinetd can not bind to both IPv4 and IPv6 on same port
Public bug reported:
Binary package hint: xinetd
I am using Ubuntu 9.10 Karmic, and have altered sysctl
net.ipv6.bindv6only so it is set to 1 - this is so that listening to an
IPv6 port does not automatically listen to the corresponding IPv4
(required for another application on this machine, unrelated to xinetd).
However, this causes problems with xinetd - it refuses to bind to both
0.0.0.0:PPP and :::PPP, where PPP is the same port number for both. And
thus only binds to the first one that it attempts. The error in the log
is bind failed (Address already in use (errno = 98)). service = XXX
The configuration looks like this:
/etc/xinetd.d/XXX:
service XXX
{
flags = IPv4
socket_type = stream
wait = no
user = UUU
server = /home/XXX/YYY.py
port = PPP
}
/etc/xinetd.d/XXX6:
service XXX
{
flags = IPv6
socket_type = stream
wait = no
user = UUU
server = /home/XXX/YYY.py
port = PPP
}
I also tried combining the IPv4 and IPv6 flags:
/etc/xinetd.d/XXX:
service XXX
{
flags = IPv4 IPv6
socket_type = stream
wait = no
user = UUU
server = /home/XXX/YYY.py
port = PPP
}
But this results in the error Service XXX specified as both IPv4 and
IPv6 - DISABLING and no binding to any interface.
I also tried adding the lines bind = 0.0.0.0 and bind = ::
respectively to the configuration files but that had no effect.
