Backporting packages.

   Sun, 22 Feb 2004 02:09:05 +0000 (GMT)

   Some of you will have expressed questions like: "When will XYZ be in stable"
   or  "is  there a backport for such and such". You can in fact backport
   packages yourself. For such cases, the following procedure works:

     (note: I maintain a number of backported debs, and this routine works)...

   1. Add a deb-src line for sid to your sources.list. Typically:

deb-src http://www.mirror.ac.uk/sites/ftp.debian.org/debian/ unstable main

   2. Run:

apt-get update

   3.

apt-get build-dep  && apt-get -b source 

   (where:  refers to the package name in question). What this will do
   is install the build dependencies for the given package, and then will build
   the package.

   4. All that is left then is to do:

dpkg -i ./deb_files.deb

Pushing files to multiple hosts

   Mon, 2 Feb 2004 10:20:58 -0500
   Ben Okopnik ([51]LG Technical Editor)

   When I teach a class, I often need to push one or more files to my students'
   systems. Previously, I would write a "for-do-done" loop and use "scp" to get
   the files across, laboriously logging in and exiting out of each system
   every time I wanted to do a transfer - painfully clunky.

   Then I did some searching on the Net and found "sshtool" by "noconflic".
   Written in Expect, it allows multiple host logins and copying. However, it
   did   not   have   a   "no  password"  mode  (i.e.,  logging  in  when
   ".ssh/authorized_keys" contains your key) and read the list of hosts from a
   list defined within the program. I've modified it to read an external file
   called "pushlist" and added a "no password" mode; this last, of course,
   requires that you first push a "~/.ssh/authorized_keys" to the host list.

                    See attached [52]sshtool.expect.txt

   First, create your "pushlist", possibly from an "/etc/hosts" on one of the
   local machines. It should contain all your target hosts, one line per host.
   Next, create your ".ssh/authorized_keys" in the directory where you keep
   "sshtool" by copying your public keys into it:

ben@Fenrir:~/sshtool$ mkdir .ssh; cat ~/ssh/*pub > .ssh/authorized_keys

   Then, push it out to your hosts (NOTE: this replaces the remote hosts'
   "authorized_keys" files!):
