Subject: lts.conf LDM_DIRECTX parameter not documented in /usr/share/doc/ltsp-server/lts-parameters.txt

Date: Sun, 08 Mar 2009 18:45:05 +0000

Package: ltsp-server
Version: 5.1.10-2
Severity: minor


LTSP's lts.conf LDM_DIRECTX option appears to work as expected,
(bypasses ssh for post-login X11 network traffic)
but isn't listed in /usr/share/doc/ltsp-server/lts-parameters.txt.gz

Alternatively it might be argued the LDM_DIRECTX mode is horribly insecure
and shouldn't be provided!

thanks for the bug report.

this was fixed in an upload to experimental a while ago, and is fixed in
the current version in unstable (5.1.62-1). sorry we didn't have it
documented with the packages in lenny.

yes, some people proposed calling is LDM_INSECURE when the feature was
introduced. :)

the need for better performance with lower end thin clients and servers is
important to the LTSP project, despite the tradeoff in security, and at least
is secure by default.
