Bug 77417 – after recompiling xorg with ipv6, xdmcp login doesn't work anymore

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Jan Slaninka 2005-01-10 14:04:50 UTC]

I've made emerge -u --newuse world and after that I'm not able to access my machine remotely with XDMCP. All configuration files remained unchaged. I think this it's IPV6 problem, this is output of X -query server:
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/nb:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
XDMCP warning: INET6 UDP socket creation failed
I've tried to recompile xorg-x11 without ipv6 support but with no effect

Reproducible: Always

Do you have your kernel compiled with ipv6?

It appears that your attempt to remove ipv6 from USE was ineffective, based on your `emerge info`.

USE=" ... ipv6 ... "

What's `emerge -vp xorg-x11` give?

[Comment 2 Jan Slaninka 2005-01-11 00:55:34 UTC]

i've excluded ipv6 only from xorg-x11 in /etc/potrage/package.use
i've tried to compile ipv6 into my kernel as a module but:
$modprobe ipv6
FATAL: Error inserting ipv6 (/lib/modules/2.6.10-gentoo-r4/kernel/net/ipv6/ipv6.ko): Unknown symbol in module, or unknown parameter (see dmesg)
$dmesg
ipv6: Unknown symbol secure_tcpv6_sequence_number
ipv6: Unknown symbol ipv6_skip_exthdr
ipv6: Unknown symbol ipv6_ext_hdr

I don't need ipv6 system, so I've put -ipv6 into USE flags and right now I'm doing "emerge -e --newuse world", I'll let you know if it helps me with the problem after emerge is done with the compilation

one more thing I've forgot to mention:
when I do "X -query machine" I get the X screen with cursor, but it's blank, xdm  doesn't start.

OMG, i've tried again with -ipv6 system and the problem persits. I really don't know what's going on. Does anyone have a clue what should solve it?
