Bug#698345: xorg: All attempts at connecting a remote X server to a SPARC host fail, irrespective of its architecture.

2013-01-21 Thread Mark Morgan Lloyd

Can you get a tcpdump trace?


I should be able to: if I bypass XDMCP it should be a manageable size as 
an attachment (even if I can't make sense of it enough to cut off the 
earlier part of the session).

Bug#698345: xorg: All attempts at connecting a remote X server to a SPARC host fail, irrespective of its architecture.

2013-01-17 Thread Mark Morgan Lloyd
Package: xorg
Version: 1:7.7+1
Severity: important

Dear Maintainer,
I run a range of development systems here of different architectures, in most
cases "headless" with connection via X usually using xdmcp. This fails with
a SPARC Wheezy host (i.e. the machine being connected to), irrespective of
the architecture of the system running the X server (i.e. the machine on my
desk): I've tried Linux (Debian and Slackware) of a number of versions, XMing
and Solaris. In general, the host presents itself via xdmcp, but once the
actual connection is attempted the connecting X server fails (i.e. it looks
as though something is being sent over the protocol that standard X servers
can't accomodate.

Connecting locally is unaffected, I believe this includes a connection to
localhost.
