Package: ajaxterm
Version: 0.10-10
Severity: normal
Tags: patch
User: ubuntu-de...@lists.ubuntu.com
Usertags: origin-ubuntu natty ubuntu-patch
OpenStack is being packaged for Debian. OpenStack ships a patched
ajaxterm. Naturally, we don't want to ship that in the OpenStack Debian
packages, so this is the second of two patches that we need in the
ajaxterm package to support OpenStack.
Add a -T option to terminate ajaxterm itself (different from the
existing timeout code which reaps dead connections). This ensures we
don't leave stale ajaxterm servers around.
Thanks for considering the patch.
