I'm working on setting up a semi-trusted sftp service, and to get it working, I need chroot capability. I've taken the /./ wuftpd magic token code from contrib/chroot.diff and put it into the sftp server. The main problem is that privileges have been dropped by the time the subsystem is exec'ed, so my patch requires that sftp-server be setuid root. Not ideal, I know, but I drop all

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.

20 / 20 hind sight, I would probably do things different today but I have most of my active record classes under different parent classes. For example: module Foo class Bar < ActiveRecord::Base ... end end The to_xml for this produces <foo/bar> .... </foo/bar> The / in a tag name is not allowed. Questions: 1) Is this a bug? 2) If so, suggestion of what to convert it to?

I successfully obtained the Asterisk code and extracted them into /usr/src. When I make and install asterisk, zaptel, libpri etc. Are they supposed to move automatically into their respective directories? I cannot find: /etc/asterisk/ /usr/lib/asterisk/modules/ /var/lib/asterisk Do I have to manually create them or this is failed install? Thanks. -------------- next part -------------- An
