 |
|
Hi,
I discovered a pretty much interesting behaviour in gentoo's Courier-Imap ebuilds (1.7.3-r1 and 2.1.1 were both tested).
Even with the IPv6 USE-Flag there was no IPv6 support compiled into couriertcpd.
This machine was build with vanilla courier-imap and works great with IPv6:
| Code: |
kerberos# strings couriertcpd | grep in6
in6addr_any
in6addr_loopback
kerberos#
|
The following machine was build by using `emerge courier-imap`:
| Code: |
kalisto# strings couriertcpd | grep in6
kalisto#
|
and no IPv6 socket showed up after starting.
Here is my config:
| Code: |
USE="acl apache2 dga ethereal gd imap ipv6 lirc maildir moznocompose \
moznoirc moznomail samba socks5 transcode usagi usb v4l xfs"
|
The affected part (grepping for inet6 / in6 in source) are the modules rfc1035 and tcpd in courier-imapd source.
But, rfc1035 and couriertcpd passed the configure with finding v6 (and even the --with-ipv6 switch was used)!
| Code: |
configure: configuring in rfc1035
configure: running /bin/sh './configure' --prefix=/usr '--prefix=/usr' '--host=i686-pc-linux-gnu' '--infodir=/usr/share/info' '--datadir=/usr/share' '--sysconfdir=/etc' '--localstatedir=/

But finally couriertcpd did not show up any IPv6 stuff....
Anybody got an idea?
