xinetd

------

A daemon for services.

*Xinetd* is a more extensible, flexible, backwardly compatible
replacement for the classic inetd super-server.

Essentially it stands in front of daemons/services and brokers access and
system resource allocations.

Inetd is (still) a viable alternative and please note that
in use Xinetd will accommodate inetd config files .
(we are not doing that here though)

Package: xinetd
Description ::
 
  replacement for inetd with many enhancements

Maintainer: Salvo 'LtWorf' Tomaselli
Homepage: https://github.com/openSUSE/xinetd
Architecture:: i386

Recommends ::

  rsyslog | system-log-daemon, logrotate, update-inetd

Size: 140624

Installation

Is as easy as ::

  $ sudo apt-get install approx xinetd

Configuration

For practical uses there are three parts to this process.

1. configure approx_
   Approx provides the engine fo the caching service
   - /etc/approx/approx.conf
    
2. configure xinetd_
   xinetd makes the service available.
  
   - create /etc/xinetd.d/approx
   - tweak /etc/services_ (optional)
   - tweak /etc/networks_ (optional)

3. configure clients apt_

1 Approx_

---------


::
   ~$ apropos approx
   approx (8)           - proxy server for Debian archive files
   approx-import (8)    - copy local .deb files into the approx cache
   approx.conf (5)      - configuration file for approx proxy server


file /etc/approx/approx.conf


approx.conf is the primary configuration file for the
location and structure of the package cache.


The first line is by far the most important.
The others are examples or defaults.

::

   ## /etc/approx/approx.conf
  
   devuan     http://deb.devuan.org/merged

   #vivaldi   http://repo.vivaldi.com/stable/deb
   #spotify   http://repository.spotify.com
   #naibed    http://mirror.internode.on.net/pub/debian
   #ubuntu    http://mirror.internode.on.net/pub/ubuntu
  
  
   # The following are the default parameter values, so there is
   # no need to uncomment them unless you want a different value.
   # See approx.conf(5) for details.

   ## set the port number in  /etc/xinetd.d/approx ##

   #$cache              /var/cache/approx
   #$interval   60
   #$max_rate   unlimited
   #$max_redirects 5
   #$user               approx
   #$group              approx
   #$syslog     daemon
   #$pdiffs     true
   #$offline    false
   #$max_wait   10
   #$curl_path  /usr/bin/curl
   #$verbose    false
   #$debug              false

   # end of working example

That's it really.
see: man approx.conf


    The single active line in the above example has implications.
    The others are examples of using approx to
    *also* mirror other distros or repositories.

So to *break this down* a little more.

::

   devuan     http://deb.devuan.org/merged


When approx receives a request with _devuan_ as the final path of the URI it

* acts as a proxy
* and caches the requested .deb packages
  under a file tree starting at::
     
    /var/cache/approx/devuan

To produce that request, the following pattern is followed in your sources.list(s)


**deb http://REMOTE.URL/devuan stable main contrib non-free**

(or deb-src)
 
This also facilitates hosting other *deb* based distributions
or smaller repositories.

So using the above #disabled examples,
requests for ubuntu or Debian would be cached under their own trees.

e.g. ::
 
  /var/cache/approx/ubuntu
  /var/cache/approx/vivaldi
  /var/cache/approx/naibed

 
Cache Note:
...........

These identifiers may be any simple unique string.
e.g. ::

  naibed
debian drawkcab
I haven't fully tested / studied / hacked or used the approx-import tool. It will, with some understandable bastardly efficiency write over any /var/cache/approx/debian (or even DEBIAN) pool ... your Thesis etal So we are avoiding that by calling debian naibed ... this should be transparent to your users of course.

2 Xinetd_

---------


man pages ::

  ~$ apropos xinetd
  xinetd (8)      - the extended Internet services daemon
  xinetd.conf (5) - Extended Internet Services Daemon configuration file
  xinetd.log (5)  - xinetd service log format
  itox (8)        - converts inetd.conf style configuration files to xinet...
  xconv.pl (8)    - inetd.conf to xinetd.conf converter
 


note
....

*You should not need to manually evoke itox or xconv.pl
unless you are moving away from inetd (classic).
Xinetd seems to cope quite well without human conversion
but you may find otherwise .*



configuration
-------------


The default /etc/xinitd.conf does little other than point to an include directory. It is in that directory that we will describe the network service for approx.

xinitd.d/approx
---------------

Create the configuration at /etc/xinetd.d/approx .

The example_ file will need adjustment to these at least:

-  bind =  10.1.1.10  an address *available on the server*
   and *visible from the rest your Local Area Network*.
   
-  only_from = 10.0.0.0/8  to allow access from *your networks*.
   hint ::

     ip r
  
     ip r | awk '{print $1}'
            (or)
     ip r | cut -d " " -f 1
        
- set "port = 9999"  to another if you need or want to. 
- see /etc/services_ and /etc/networks_ below for some convienient alternatives.

approx starts and stops with its own user and group; approx .
These  were set up when installed.
     

example_
--------

::
  
   ## /etc/xinitd.d/approx  -*- conf -*-
   ## description: approx is a caching Debian package proxy


   service approx
   {
   id           = approx
   disable      = no
   only_from    = 127.0.0.1/8 10.1.1.1/8
   protocol     = tcp
   socket_type  = stream
   wait         = no
   bind         = 10.1.1.10   
   port         = 9999

   #    per_source  = 10
   #    max_load    = 3.0
   #    nice        = 12

services
........

Optionally you may add an entry to /etc/services
e.g.

::
   approx          9999/tcp       # approx deb package proxy

xinitd and other applications will use this entry if there is no other configuration option set.

  
networks
........


Optional and convenience for netstat and xinetd reports.

::

   default         0.0.0.0
   loopback        127.0.0.0
   link-local      169.254.0.0
   MYLAN           10.0.0.0
   OTHERLAN        172.16.0.0

This file is accessed (read) by many tools, mostly for reporting network spans in text format. Xinitd will search this file for network names if given. In particular ::

  only_from    = 127.0.0.1/8 10.1.1.0/8 172.16.0.0

may be written as ::
 
  only_from  = loopback MYLAN OTHERLAN

see: man xinetd.conf
------------------------

3. Clients Configuration

------------------------

apt

...

All that needs attention on the clients is to set up

/etc/sources.list or /etc/sources.list.d/files.list
::
  
   deb http://10.1.1.10:9999/devuan stable main contrib non-free
   deb-src http://10.1.1.10:9999/devuan stable main contrib non-free

It is also possible to set a proxy under /etc/apt/apt.conf.d/
and use standard sources.lists. This is particulaly useful for mobile devices.
However it does mean you have to be carefull to keep the final URI path unique.

e.g.
Create a file under /etc/apt/apt.conf.d/
say 00-homelan-proxy or 00-package-proxy

The contents should be adjusted to match your network but approximately ::

  // /etc/apt/apt.conf.d/00-package-proxy
  // use this proxy when at home
  Aquire::http::proxy "http://10.1.1.10:9999";
  // use this at Bilbo Baggins's
  // Acquire::http::proxy "http://cacher.bilbonet:3128";
  // Only one enabled please.
 


address resolution
..................


/etc/hosts may or may not be convenient.
::
  
   127.0.0.1    localhost
   10.1.1.10    cache.mynet cache

A Local Deb Package Mirror

     (( with Devuan xinetd and approx ))

There are a number of ways to build a shareable "mirroring cache" of packages on a non public Network. This saves bandwidth, time, and possibly enables disconnected use with some small tweaks.
This post is a shorter description of one possible process. There is a longer even more verbose version one post later.

e.g. These proxies all scale to small enterprise level at least.
I have used them all successfully at some time or other.

  * squid-deb-proxy - Squid proxy configuration to optimise package downloads
  * apt-cacher-ng - caching proxy server for software repositories
  * approx - caching proxy server for Debian archive files


The squid approach (? probably ?) supports multiple connections better than the last two. Though thats just a guess, for more industrial uses its worth at least a look. It works OK on a home LAN but not on any machine you reboot a lot.
Waiting for squid to shutdown can get "old" quite quickly.


This Walk through documents setting up a HTTP based proxy using
*approx_ and xinetd_*.

Features of this approach include:

  - Reliable and _low_ maintenance
  - Small and light enough for home use
  - efficient enough for enterprise level deployment.
    Should scale up to 100's of LAN clients including virtual systems.
    (depends on hardware and bandwidth)

  - Tunable access by network space or whitelist
    and optionally time of day. (xinetd)
    (No need to worry your iptables or other filtering.)
  - Tunable system loads and concurrency.  (xinetd)
   
  - A simply structured *pool based mirror*  under /var/cache/approx  (default).
  - Readily and cleanly supports other Debian type systems
    and 3rd party repositories
 
  - Low standby resource demand (xinetd)
  - Fast start up and shut down. (xinetd)

  - Logs flexibly. To file or syslog. ( approx and / or xinetd )

The downsides are:
  - editing the clients sources.list . (though there are options around that even)
  - setting up xinetd the first time may be an issue. 
  - this is not a simple apt-get install  and walk away.
_You_ will have to create at least one new file and edit all your clients sources.lists.

However its really not difficult take your time and test as you go.

The Shortest Version

root@yours~# apt-get install xinetd approx

The Short Version

Adjust values to suit network(s) and remote repositories.

root@yours~# apt-get install xinetd approx

 1. edit the servers
/etc/approx/approx.conf
::
    devuan http://deb.devuan.org/merged



 2. edit a clients sources.list. e.g.
/etc/apt/sources.list.d/01-stable.list
    (? disable the rest while you test ?)
    *The client can be the same machine as the server.*
   
 ::
    deb http://10.1.1.10:9999/devuan stable  main contrib non-free

 3. create xinetd approx service file at
/etc/xinetd.d/approx
   
 ::
    # /etc/xinetd.d/approx
    service approx
    {
    id           = approx
    disable      = no
    bind         = 10.1.1.10   
    port         = 9999
    only_from    = 127.0.0.1/8 10.1.1.1/8
    protocol     = tcp
    socket_type  = stream
    wait         = no
    user         = approx
    server       = /usr/sbin/approx
    }

4. Restart xinetd

::
   root@yours~#  /etc/init.d/xinetd  restart

   (or)

   root@yours~#  service xinetd restart

check xinetd has enabled your new service ::

    you@yours~$  netstat -tan | grep 9999
   
    you@yours~$  nc 10.1.1.10 9999

        "get foo"

        HTTP/1.1 400 Bad Request
        Server: approx/5.10 Ocamlnet/4.1.2


(yes that *nc get*  is deliberately broken)

    you@yours~$  CTL c
  
to close the "conversation".

5. check default logging (and any errors like the one above)

::
  you@yours~$  tail -f /var/log/daemonlog

something like: *Nethttpd: Bad request line*

6. simple test from the configured client

::
   root@yours~# apt-get update

see:    /var/cache/approx/

The Long Version includes more options and some alternatives.

Xorg Goes Out Of Action (again)

Trouble running xorg as normal user ?
Finding nothing useful in the X logs ?
Does startx or xinit work for root but not for you ?
Does your "Display Manager" (slim or {g,x,k}dm* or lightdm)
startup fine but fail to allow you to log in ?

You may be using devuan or debian or arch or even NetBSD .

Try this it _may_ help:
log in to a real terminal / console .

( something like )

ctl+alt+F2

try: you@yourhost~$ startx

No go ?  Then try this:
you@yourhost~$ mv ~/.xinitrc ~/xinintrc.copy

Now again: you@yourhost~$ startx

If that works :
1/ You need to ask your window manager / session manager
to run any apps you had auto starting in .xinitrc.
2/ You will also have to select _your_ desktop from the
display managers options or set the system default ...

ELSE Still no go ?

Bummer leave everything above done as is.
Next check that :
Your using xwrapper to allow X to create and destroy sockets on your behalf.
you@yourhost~$ man Xwrapper.conf
Its a short man page have a quick look.
see: /etc/X11/Xwrapper.conf
This has to exist and is activating the following settings :
#######################
#allowed_users=anybody
allowed_users=console
needs_root_rights=auto
#######################
See the man page for other options.

Try startx again if still no go you may have to install the Xwrapper:

Note / aside / man-splainer :

This apparently is now considered legacy or rather the assumption that your
using the systemd auth chain seems to be the thing to do.
So you could drink the grey gruel cordial ... or

You may need to install ""legacy"" versions of xorg
e.g.
you@yourhost~$ apt-cache search xorg | grep wrap
==> xserver-xorg-legacy
(so go install that )
So now at least you can startx or xinit or X -query from a console.
Which is all I need.
Try lightdm if you need a Graphical Login / Display manager ...
If you need xdmcp may Gandalf help you :)
Do feel free to pass on my best wishes to the XDG Systemd *kits mafia .

They seem to also have broken PAMs auth chain ...
Hey bloat obfuscation and spaghetti is always better than simple and clean. Also BSDz are cool too.
The Hairiest shirt of all is NetBSD and it works fine !
Its quite possibly about and past time we had a proper minimal Linux distro. Devuan is cool though has the assumption that the "only" thing wrong is systemd.
FWIW I have no need or want for systemd in _any_ aspect:
- I like and even use runlevels or even simple rc.d
- Its fine for it to be in place it just need not be compulsory.

MAJURO DECLARATION FOR CLIMATE LEADERSHIP

Following is an hand formatted copy of the Majuro Declaration for Climate Leadership.

The Majuro Declaration Web Site. The Canonical Source for information.
http://www.majurodeclaration.org/the_declaration

MAJURO DECLARATION FOR CLIMATE LEADERSHIP

1.   Climate change has arrived. It is the greatest threat to the livelihoods, security and well-being of the peoples of the Pacific and one of the greatest challenges for the entire world.

2.   There is an overwhelming scientific consensus that escalating greenhouse gas emissions continue to cause the sharp rise in average global temperatures over the past century, the alarming acidification of our oceans, the rapid loss of polar sea ice, sea-level rise, and the striking incidence of more frequent and extreme weather events all over the world.

3.   On 9 May 2013, atmospheric concentrations of carbon dioxide measured near the summit of Mauna Loa in Hawaii exceeded 400 parts per million for the first time since measurements began. In crossing this historic threshold, the world entered a new danger zone. Unless we quickly change course, global average temperatures are projected to rise by 4C or more above pre-industrial levels by the end of the Century, resulting in unprecedented human and environmental impacts.

4.   We,, the Leaders of the Pacific Islands Forum, underline the need for urgent action at all levels to reduce greenhouse gas emissions commensurate with the science and to respond urgently and sufficiently to the social, economic and security impacts of climate change to ensure the survival and viability of all Pacific small island developing States, in particular low-lying atoll States, and other vulnerable countries and regions worldwide.

5.   At the same time, we recognize that the necessary energy revolution and economic transformation to low carbon development is an unprecedented opportunity to enhance our security, protect and ensure the sustainability of our natural resources and environment, and to improve our people's health.

Our Responsibility to Act

6.   We confirm the responsibility of all to act to urgently reduce and phase down greenhouse gas pollution in order to avert a climate crisis for present and future generations.

7.   The responsibility of all to act falls to every government, every company, every organization and every person with the capacity to do so, both individually and collectively.

Our Commitment to be Climate Leaders

8.   We commit to be Climate Leaders.

9.   To lead is to act. In supporting this Declaration, a government, economic entity, company, civil society organization or individual commits to demonstrate climate leadership through action that contributes to the urgent reduction and phase down of greenhouse gas pollution.

10.   Recognizing our unique vulnerability to climate change, the predicted catastrophic impacts on the security and livelihoods of our people, and the significant benefits that come with our transition to renewable, clean and sustainable energy sources, we, the Leaders of the Pacific Islands Forum, confirm our climate leadership in the form of the commitments listed at the end of this Declaration. We also want to do more.

11.   We call on our partners to enhance, accelerate and ensure the effective delivery of their support for the design and implementation of the commitments of the Pacific small island developing States.

12.   We also call on others, in particular our Post-Forum Dialogue Partners, to contribute to the urgent reduction and phase down of greenhouse gas pollution.

13.   This Declaration is a platform for an upward spiral of action to urgently reduce and phase down greenhouse gas pollution. Those who support this Declaration are strongly encouraged to continue to scale-up their efforts by submitting for listing further specific commitments that contribute more than previous efforts to the urgent reduction and phase down of greenhouse pollution.

14.   In addition, we commit to accelerate and intensify our efforts to prepare for and adapt to the intensifying impacts of climate change, and to further develop and implement policies, strategies and legislative frameworks, with support where necessary, to climate-proof our essential physical infrastructure, adapt our key economic sectors and ensure climate-resilient sustainable development for present and future generations.

15.   This Declaration will be presented by the Chair of the Pacific Islands Forum to the Secretary-General of the United Nations as a contribution to his efforts to catalyze ambitious climate action and mobilize political will for a universal, ambitious and legally-binding climate change agreement by 2015.

16.   This Declaration and the actions under it are intended to complement, strengthen and augment processes under way and commitments already made, including those under the United Nations Framework Convention on Climate Change and its Kyoto Protocol.

17.   We agree to review the status and implementation of this Declaration at the 45th Pacific Island Forum Leaders' meeting.

Adopted in Majuro, the Republic of the Marshall Islands, on this, the 5th day of September, 2013.

Advanced and major emitting developing countries take action fully commensurate with their respective capabilities; 4. There is an effective set of rules for land use, land-use change and forestry (LULUCF); and 5. There is full recourse to a broad and efficient international carbon market.

Thorium Based Nuclear Power Is An Option

This page is not meant to be an in depth study of Thorium Reactors. Its an introduction to the fact that they have existed and are about to exist again. They have many benefits, and are a much more useful and manageable process than any current solid fuel Uranium based reactors.

You know those times , online usually, when some often well intentioned fellow traveller says that nuclear is the only truly green option ....

You / they / we may have read this
Treating the Symptom

Which doesn't really make a great case for keeping the current stock of Reactors. Or believing that a new crop has all bases covered.

The core arguments include;
• carbon capture is cool but not up to it.
• safer than coal.
• new reactors are safer than old designs

Well, assuming that the usage case implies a very high density fuel (as implied by Nukes), ask them why Thorium is not an option worth exploring.
If your going to exploit some of the most dangerous stuff in the solar system you may as well get it as right as it can be.
The safe operation of such potentially dangerous production, supply and disposal processes
should be intrinsically safe.
What are you going to be doing 200 years from now ?

The World Nuclear Association, has a page on thorium.
Wikipedia does as well. With references and cross links.
Thorium Nuclear power

Norway has a start and they have an abundance of North Sea Hydrocarbons.

This blended method can be readily used in rod type reactor... well maybe you wouldn't retrofit .. no idea how hard that would be.

Then there are Liquid (fluoride) Salt type reactors, a much better long term and scalable solution.
Liquid fluoride Thorium Reactor

Its all right there with references .

Finally point out that they are weighting the "base load" thing , and the "energy density" thing, mythologies way too highly in any case.
But hey, there are places it makes some sort of sense:
Norway India and China think so.

• Places with high population densities and low access to space and renewable energy, are one.
• Places where Nuclear and associated grid / support structures are already in place. These reactors can even help consume (some of) the waste.

Building and Installing E17 from stable release

When edje wont build

Summary:
check for previous (obsolete) installs for EFL and E17 development packages.

Its April 2013 as I write this.
Over Easter  I finally got around to _successfully_ building the latest Released (stable) version from the Enlightenment Main Site .
See:
The Released page.

Now this is (should be) straight forward enough essentially you build the Enlightenment Foundation Libraries then build the desktop manager/shell  (E17) and away you go. The usual caveats around building from source apply of course. You will need quite few other dev libraries that you may or may not have in place.


If you get all the way to edje and then it breaks, before you waste a heap of time manually relinking and checking $PATH and permissions, reading all the ./configure --help(s) ... and grepping through code tracing the linkages ...
googling around in circles ...

Do yourself a favour purge all the packaged development libs and apps or simply move them out of the way.

I had only purged e17-dev and this was not enough.

((DOH) Well of course it wasn't I was building the Foundation Libraries, the desktop (e17) may be treated as a nice side effect :)

I had totally forgotten I had installed the Debian prepacked versions months ago for reasons I now only vaguely remember.

Here is list of them for Debian (.deb) based distros I expect they will be very similar for others.

  libedje-dev - libedje headers and static libraries
 libeet-dev - Enlightenment DR17 file chunk reading/writing library      development files
libefreet-dev - Development files for libefreet and libefreet-mime
libelementary-dev - Development files for libelementary
libevas-dev - Enlightenment DR17 advanced canvas library development files
e17-dev - Enlightenment headers, static libraries and documentation

I suspect its the edje and possibly the e17 devs that cause issues that are not resolved by the $PREFIX settings at build time.

The symptom is that edje wont build as its compile gets pointed to old versions of its precursors. (dependencies)


./configure wont warn you about this :)

So as your going to be building from source anyway you may as well --purge them. Some equivalent to :

apt-get remove --purge libedje-dev libeet-dev libefreet-dev libelementary-dev libevas-dev e17-dev

I haven't looked into the details but will note that most ./configure (s) appear to have options that would also solve the issue ... I can't see the point having them as they are way out of date and now (soonish)  not needed.

Other thoughts and notes:
  Use the released tarballs at least at first, getting the developers latest stuff is quite massive and probably in a rapid state of flux in any case.
(Lets not talk about WTF is going on with VCS ...)
In any case you will need to gather some familiarity before doing SVN or bzr <-> git.


So with this in mind or some functional equivalent as you see fit go ahead and start again :)

I will post a step through next post.
Its quite doable following the instructions at the main site.
(and avoiding the developers docs which may lead you to dark places)
