I use Debian Linux for my desktop for quite some time; Even though there are plenty of MP3 / CD players around in Debian, I’m used to the good old XMMS, hence I often prefer to use XMMS to play my music instead of newer players like RhythmBox or audacious. Actually audacious is not bad substitute for XMMS and is by default part of Debian but to me it seems more buggy and tends to crash during playing some music formats more than xmms ….
As most people might know, XMMS is no longer supported in almost all modern Linux distributions, so anyone using Debian, Ubuntu or other deb derivative Linux would have to normally compile it from source. Compiling from source is time consuming and I think often it doesn’t pay back the effort. Thanksfully, though not officially supported by Debian crew XMMS still can be installed using a deb xmms prebuilt package repository kindly provided by a hacker fellow knuta.
Using the pre-build deb packages, installing xmms on new Debian installs comes to:
I’m bulding new iptables firewall on one Linux server. The Debian GNU/Linux is required to act as firewall do Network Adress Translation for a small network of office PCs as well as forward some of the inbound ports to hosts from the local network located behind the router.
The local network besides the router had an IP addressing in the class C network e.g. (192.168.1.1-255)
First I procceded and enabled the Network Address Translation via the Linux kernel variable:
Initially I even forgot to switch on the net.ipv4.ip_forward to 1 (by default this value is set to 0) – GNU/Linux’s default network behaviour is not predetermined to act as network router. However, since I haven’t configured Network Address Translation for quite some time it completely slipped my mind!
Anyways next the actual iptables rule which makes NAT possible I used is:
Whether xxx.xxx.xxx.xxx is the External IP address assigned to the router on eth0
With this very simple rules now Network the local network is capable of accessing the Internet withotu problem.
It’s a good time to say that still many system administrators, still erroneously use MASQUERADE rules instead of SNAT . IP MASQUERADING is an ancestry from ipchains and these days should be completely abandonded, especially where no often change of primary IP address to access the internet is made. For dial-ups or other kind of networking, where the IP addresses are often changed still IP MASQUERADING might be a good idea though.
My next goal was to make the Linux router to do port forwarding of Traffic which arrives on port 80 to a IIS server assigned with a local IP address of 192.168.1.5 I did the webserver (port 80), port forwarding from IP xxx.xxx.xxx.xxx to 192.168.1.5 with the iptables rule:
There was a requirement to do port forwarding for a Windows remote Desktop running on standard port 3389 from the router to the internal Windows IP address running the IIS webserver, however the company required me to only allow access to the rdesktop 3389 port to certain real IP addresses. Initially I thought about using the above PREROUTING rule which makes the port redirection to the IIS server and only change port 80 to port 3389 , and then use filter table INPUT chain rules like:
Adding this rules did not added any filtering to the forwarded remote desktop port. I suspected that somehow probably my above PREROUTING nat rules are read before any other rules and therefore automatically allows any IP address to port fortward traffic. I’ve checked the iptables documentation and it seems my guess was partially right.
When some kind of network traffic enters the iptables firewall it first goes through the PREROUTING channel and then the traffic flows in a certain order.
The iptables network packets flow is clearly seen in above’s diagram a thorough looks gives a very good idea on how packet is being processed by iptables
Finally as I couldn’t think about a good solution on how to only filter the port redirected traffic, which always firstly entered in the POSTROUTING chain, I’ve consulted with the guys in irc.freenode.net in #Netfilter.
I’m quite thanksful as a guy nicknamed Olipro has given me a pretty good picture on the port forwarding POSTROUTING problem and has provided me with a very logical easy and great fix. He suggested that I only do port forwarding for certain IP addresses instead of allowing all IP addresses and then lookup for a way to allow only some of them and filter the rest.
The iptables rule to restrict the incoming traffic to the remote desktop forwarded port 3389 to few only allowed IP addresses looks like so:
Now the three sample IPs passed xx1.xx2.xx3.xx4,1xx,2xx,3xx,4xx,xxx.xxx.xxx.xxx has added to port forward traffic on 3389 to 192.168.1.5
By the way I did not know that newer versions of iptables support passing by multiple IP addresses to the –source or –destination IP. This is really great feature I’ve learned from the good guys from #Netfilter. However one should be careful when using the multiple IPs with -s or -d, it’s really important that the passed consequent IPs has no space between the , delimiter.
Now that’s all my task is completed. All computerse inside the Network 192.168.1.1-255 on the Linux router freely can access the Internet, all IPs are also capable to access the IIS server located behind the NAT as well as only certain IPs are capable of accessing to the IIS remote desktop. Hope the article helps somebody 😉
A friend of mine who is a devoted Orthodox Christian (and ipodqkon Georgi), regularly visits Holy Mount Athos as a pilgrim. On a few times he has been there serving to the workman who are currently restoring a number of monastery building which has been abandoned for quite some time.
Every Sunday morning he also goes to the Monastery Church St. George Zograph for the monks Holy Liturgy service. He send me few recordings he made with his phone during the Holy Liturgy monks chanting. The recording’s quality is quite raw as however still it’s very invaluable piece of spiritual music, which I think every spiritual person will highly regard and enjoy.
Here are the 12 songs which he send me over skype I hope the songs, will be enjoyable and a spiritual blessing to some Christian brothers and sisters out there:
I have noticed that many blogs nowdays offer an email subscription box to simplify the subscription procedure for the blog readers.
My blog was lacking this feature so I took the time to find out how can I add an e-mail subscription box field on my blog. My research has shown me that the easiest way to add the subscription box is by using Google’s Feedburner RSS service . I’ve been using Google FeedBurner for quite some time and I’ve already 27 subscriptions with it. Earlier when I added a FeedBurner subsciption to my blog I’ve blogged about it, so if you’re not acquainted on how to add FeedBurner service to your blog, you might want to read my previous article Adding RSS Feed to WordPress in conjunction with FeedBurner / WordPress add-to-any-subscribe plugin
In this article I will explain in short step by step, how to add the subscrpition email box to your wordpress I assume, that the reader has already enabled and configured registration with Feedburner, if you still haven’t just skip few lines above and check my previous article. I would hereby skip the explanation of why feedburner as an RSS is so advantageous for every blog owner and readers and skip further to the email subscription procedure step by step instructions: Step 1: Login to your FeedBurner Account
In my case my feedburner account url is accessed via the URL http://feeds.feedburner.com/WalkingInLightWithChrist-FaithComputingDiary
I have been properly logged in to my feedburner, so to view statistics of my current feeds subscription and to configure various variables of feedburner I had to access the URL address: http://feedburner.google.com/fb/a/myfeeds, a very quick shortcut to my feedburner account settings is also avaialable by simply accessing the URL: http://feedburner.com
Step 2: Click on the link that saysMy Feeds
If you have configured feeds for your feedburner you will get the list of feedburner feeds, (one could have multiple feeds, let’s say if you have a couple of blogs or sites and you use one feedburner account to podcast your feeds for each of the separated blogs or sites.
Step 3: Click over the feed you want to have the feedburner email subscription box
Below you see the screenshot of my configured feedburner feed:
Right after clicking on your configured feed in my case Walking in Light With Christ – Faith, Computing, Diary you will see the screen:
Step 4: Click on Publicize menu
You will see the following two screens while scrolling with your browser:
You see in the second screenshot above there is a textbox with a html form code, to set the feedburner subscription to appear on your blog you need to copy/paste this code and put it on your blog.
After copy/pasting the code, don’t forget to scroll down in your browser and save the email subscription generated form settings, (NB! if you don’t save it it want be working even if you install it on your blog). Here is the Save button screenshot:
Step 5: Setting up feedburner email textbox to wordpress
In order to set up the just copied html and css form code you need to login to your wordpress blog admin and go to:
Appearance -> Widgets
Scroll over the Available Widgets list, find the Text Widget and press the Add button to include the Text Widget to your blog sidebar.
Further on the same Widgets page, go to the Sidebar menu find the just added Text Widget and click over the Edit link:
Here is my screenshot of the edit screen of the Text Widget:
Step 6. Add the feedburner email subscription box to single posts blog views
This step is not a requirement, but I found it for myself to be vital, as it might rise some more subscribers to my blog, if my blog readers finds individual indexed pages in Google.
This step is also highly dependant on the wordpress theme you use, I use the old wordpress default theme and it’s default behaviour is not to show up the wordpress sidebar, whether an individual wordpress post is clicked over, therefore to enable my feedburner subscription box for individual posts I also need to place the form code obtained from Feedburner.com’s to my templates single.php
If you’re using some kind of theme that doesn’t have the non-sidebar single post behaviour you might skip forward this step, otherwise just continue on reading.
To include the feedburner email form subscription to my single posts I edited blog/wp-content/themes/default/single.php
In the single.php file find the code:
<?php comments_template(); ?>
Immediately after the above code place your feedburner form code, like you see in below screenshot:
Again this step is voluntary and is not necessery I’ve disliked the default way the form is formatted so I played a bit with few of it’s values to customize it to my likings, the things which I have changed a bit in the provided feedburner form code was:
Remove the Delivered by Feedburner text from the form
>To do so in the issued feedburner form code below when you copy the code paste it to some text editor and remove from the code the text:<p>Delivered by <a href=”http://feedburner.google.com” target=”_blank”>FeedBurner</a></p>
– Change the subsciption box width and height:
style=”width:140px”Changed that to:style=”width:120px”also I’ve changed:’scrollbars=yes,width=550,height=520’to:’scrollbars=yes,width=450,height=420’Another point of interest for adjustmnets in the feedburner for are in the form code:
Remove feedburner subscription form default bordering
form style=”border:1px solid #ccc;padding:3px;text-align:center;”I’ve changed that to:form style=”border:0px solid #ccc;padding:2px;text-align:center;”By changing the css values border:1px to border:0px I have instructed the subscription box to show up without borders.
That’s all now refresh in your browser and check if the feedburner email subscription form is showing up properly to your wordpress. To completely ensure yourself it works correctly try to subscribe yourself to the form and during your next blog post you should receive an email notifying you about the newly written article.
You can see, my blog feedburner subscription form on the blog right sidebar or on the below picture:
For all of us who yet remember the Demoscene , Purple Motion, Necros and Skaven are absolutely legendary names. Their music work contribution for tracked Electronic music, video games music and general development of the IT culture is truly invaluable.
Many younger computer users (I’m 26 now), and probably IT starters would probably never heard about neither Demoscene nor Purple Motion or the other three patriarchs of tracked Electronic music.
This musicians have a special value for people who has ever composed music with Impulse Tracker and the many other programs to compose music from samples.
Purple Motion has his own home page for quite some time now, however I just noticed that he has recently turned his home page to a PHPBB Forum where there is plenty of information about the composer as well as open discission and many questions and answers of people who are interested into the great electronic composer.
The third by significance electronic musician who is probably known by the many old school computer users and musicians is Skaven . Skaven is part of the Future Crew .
One of the most notable Skaven music works is actually the soundtrack song produced for the Second RealityDemo . It’s worthy to say few words about Future Crew as well, Future Crew (link to wikipedia) – “Future Crew is a now-defunct group of Finnish computer coders and artists who created PC demos and software, active mostly between 1992 and 1994.” You might also consider checking Necros profile in modarchive There you can find plenty if not all of his works for download and listening. A descendant of the the 3 up-mentioned wonderful tracker musicians is Pro-XeX also known under the artistic pseudonim Necroleak Though his works are much later first originating from the distant 1995 his works are comparable by quality and goodness to (PM, Necros and Skaven’s works). If you really want to completely turn back some memories about the good old times when we used to use DOS environment and to listen the great old MOD, S3M, XM etc. songs with the good old Cubic player which is already available under the free port called Open Cubic Player
Under Debian Lenny, Squeeze/Sid installing opencubicplayer is pretty easy and comes to simple installation via apt-get as follows:
debian-desktop:~# apt-get install opencubicplayer
First time I’ve noticed Cubic player I should admit it was a real joy to know there is already a Unix port since Linux and BSD are my OS choice for almost 10 years already. Another possible way to play the old school songs on Linux is through the well known console player mikmod I’ve prepared a downloadable song archive for each of the 3 great electronic composers (Purple Motion, Necros, Skaven) on my personal webserver.
I haven’t blogged for quite some time. First I glorify the Almighty God our Blessed Holy Trinity for his abundant mercy towards me!! Glory be to the Father, The Son and The Holy Spirit! Now and forever and ever! Amen. I start with this loud words and I have so many things to say. But yes yesterday a joyful news came to me it seems my Exemption letter for Internship has been Approved! I prayed to God that he make them approve this exemption letter because I want to graduate asap and go back to Bulgaria. Here in the Netherlands I feel really terrible, the spiritual state of the country is simply softly said terrible, even though they seem to be an advanced country from the tangible aspect of the things from the intangible/spiritually poor. Not to say that I feel like the devil is controlling most of their lives already. The complete mix of negroes, chinese, indonesians and all other type of races makes the country mixed. Here in the air it feels like a spirits of gluttony are crawling around all the time, also quite often I feel like madness crossing around the air. Sometimes I have that strange thoughts in my mind that something is really wrong with that country. Maybe I had a nice point about that.This SHR project is getting schizophrenic, anyways glory be to God for his abundant mercy towards me and sustaining me always. Yesterday was a terrible day I felt so confused such a profound spiritual sorrow was rulling me that I can hardly bear it, I had a couple of terrible days this days. Since some time I am suspecting there is something wrong here, everytime I have classes with most of the teachers here I feel terrible afterwards and I usually need a couple of days to recover to some sane state. In their presence I experience profound spiritual sorrow and suffering, I’ve been in a similar spiritual states before and I know that this simply can be described in the biblical word hell. Since some time I suspect something is wrong with this guys (I mean the tachers), a couple of days Mr. Joop Vinke the guy who seems to be like a dean to us mentioned during some of the theater sports answered my question where have been yesterday “to the rotary club” and then he added like every other day before, it was not clear is he mean it or not. My suspects became even stronger, because I know that one of my employers used to be attending rotary club as well I know some really terrible things happened in his life and I think he quit that club, anyways. Last week on Friday I met one of my other teachers (Mr. Da Ponte) and I spoke with him, the conversation flowed as he mentioned something about the Lord making the sun circle around the earth, I was interested by his statement so asked him if he believes in God and if he is a roman catholic. He said he is not roman catholic and then what followed was a sort of preach about what he believes and his God as I continusly asked him questions. From his description I left with the impression that he is probably believing in the same God of the masonry (I’ve red about that just a couple of days before). So many things matched, the teacher even mentioned that a lot of teachers in that school are also believing in God and I was left with the impression that he meant the same God as he believes, so I make the connection that they are probably rotarians, masons or taking participation in some sort of organization like that which has to deal pretty much with the occult. A couple of days before I spoke with a brother in Christ (Stelian) and I explained him what is happening and about this BHC (business ethics classes), I explained him how much they want you to accept what they say and if you don’t you are not worthy, I also explained to Stelio the whole story and how this guys are able to make you feel really bad. Since this guys tried to teach us their methods and I tried a couple of times their methods and saw the effect how by doing “something” “unconsciously” you can alter the other into a state of broken spiritness and terrible suffering while at the same time you feel overflowed with joy, a sort of stealing his living power or Angels so to say. I don’t want to enter into details about that since its to me surely related with demonic manifestation. I’ve also remembered that one of the guest lecturers that Mr. Vinke has brought here mentioned that he is rotarian, the coincidences started becoming too much seriously. I also spoke with a student who has graduated and I asked him if he feels that bad thing inside of him, I was stunned when he confirmed. Also in that SHR project it really is schizophrenic I feel that spiritually something really wrong is happening there I started thinking and I could recognize many of the things done in classes of Mr. Vinke has to deal with the paranormal even though not openly showed, even his theater sports has a lot of unconscious spiritism involved, not to mention his Werewolf games including vampires, whitches etc. a lot of the theater sport games include games which include things with dying, you play dead etc., etc. I also have noticed that teachers often are pointing me and saying that I’m not changing, many of the students here are changing seriously for bad. I know by my saviour Jesus Christ who said “by their fruits you will know them”, seeing their fruit suffering, confusion, hate, lies etc. I started being more and more convinced that this guys are dealing with the devil. So if my theory is right and I think it probably is, most of the teachers are members of the rotary club. Maybe they even see it as harmless way to improve their business contacts but I know this is not the case, and this guys are giving oaths, having their strange believes spiritual leaders and do worship the devil even though not openly. I shared all that with a couple of my colleagues and many of them probably just thought that I’m out of my mind. But the holy spirit in me testified all that the things I am thinking are true. I’ve shared what is happening with a brother in Christ (a priest) in the orthodox Church Bulgaria and he said he is gonna mention my name on the altar before God on the Divine Liturgies. I guess this matters because today even though I am not completely okay I feel much relieved and better and I feel God! Glory be to the Immortal and Holy of Israel now and unto ages of ages. I try to learn the gospel a bit early in the morning and a bit late at night before I go to bed I also try to pray a bit each morning and evening and trust the Lord to keep me and protect me from the schemes of the evil one! Yesterday I was at Ina’s place and tried to explain her that this project we do now has something to deal with evil spiritism. I even have suspected that this guys from the rotary club ask their members to share information about certain people that the rotary members work with and then try to bring some curses and spells if they see somebody as a problem to their practices. I suspect that this guys somehow use their members as a channels to spread their evil spirituality. I’ve also taken the advice of Stelio to start caring an Icon in me whenever I go to school. Quite often here and especially in the dormitory I feel something is happening inside of me, my heart starts beating unsteady I also feel spirits flying around and trying sort of trying to conquer me this more or less has to deal with their broken spirituality here. Often I feel completely exhausted like somebody stealing my living power and willingness. Also I have noticed that here in their discoteques, they don’t allow you to enter with a hat? My assumption is that there are somethings placed in the discoteques which has to deal with inducing thoughts in you. On saturday I and Sali entered into a discoteque, I was not so willing so I’ve removed my hat I’ve borrowed temporary from Sali. After being in the discoteque on the day after and on Monday I had terrible headache and felt weak and pretty much like almost dying, Also I felt something on my forehead happening, just like I felt on a numerous times the Holy Spirit annointance and the Lord’s spiritual sign on my forehead, I’ve red in revelation that the Antichrist is going to put something on ppl’s forehead and and their right hands I’m more and more starting to think that this in some phase is already working, I’ve felt aches on my right hand on a numerous occasions, here often Its like I fight for my spiritual survivance. People around I see as they’re dead and just living to consume “limed tombs” as they are called in the gospel. I know that all I’ve written here might seem like too much of a conspiracy, however I’m pretty much sure that many of the things I suppose are true to a certain high degree or even completely.END—–
