• Malware - Technical anlaysis

  - by nullptr

  Note: Please do not mod down or close. Im not a stupid PC user asking to fix my pc problem. I am intrigued and am having a deep technical look at whats going on. I have come across a Windows XP machine that is sending unwanted p2p traffic. I have done a 'netstat -b' command and explorer.exe is sending out the traffic. When I kill this process the traffic stops and obviously Windows Explorer dies. Here is the header of the stream from the Wireshark dump (x.x.x.x) is the machines IP. GNUTELLA CONNECT/0.6 Listen-IP: x.x.x.x:8059 Remote-IP: 76.164.224.103 User-Agent: LimeWire/5.3.6 X-Requeries: false X-Ultrapeer: True X-Degree: 32 X-Query-Routing: 0.1 X-Ultrapeer-Query-Routing: 0.1 X-Max-TTL: 3 X-Dynamic-Querying: 0.1 X-Locale-Pref: en GGEP: 0.5 Bye-Packet: 0.1 GNUTELLA/0.6 200 OK Pong-Caching: 0.1 X-Ultrapeer-Needed: false Accept-Encoding: deflate X-Requeries: false X-Locale-Pref: en X-Guess: 0.1 X-Max-TTL: 3 Vendor-Message: 0.2 X-Ultrapeer-Query-Routing: 0.1 X-Query-Routing: 0.1 Listen-IP: 76.164.224.103:15649 X-Ext-Probes: 0.1 Remote-IP: x.x.x.x GGEP: 0.5 X-Dynamic-Querying: 0.1 X-Degree: 32 User-Agent: LimeWire/4.18.7 X-Ultrapeer: True X-Try-Ultrapeers: 121.54.32.36:3279,173.19.233.80:3714,65.182.97.15:5807,115.147.231.81:9751,72.134.30.181:15810,71.59.97.180:24295,74.76.84.250:25497,96.234.62.221:32344,69.44.246.38:42254,98.199.75.23:51230 GNUTELLA/0.6 200 OK So it seems that the malware has hooked into explorer.exe and hidden its self quite well as a Norton Scan doesn't pick anything up. I have looked in Windows firewall and it shouldn't be letting this traffic through. I have had a look into the messages explorer.exe is sending in Spy++ and the only related ones I can see are socket connections etc... My question is what can I do to look into this deeper? What does malware achieve by sending p2p traffic? I know to fix the problem the easiest way is to reinstall Windows but I want to get to the bottom of it first, just out of interest. Edit: Had a look at Deoendency Walker and Process Explorer. Both great tools. Here is a image of the TCP connections for explorer.exe in Process Explorer http://img210.imageshack.us/img210/3563/61930284.gif

• Having troubles connectiong Magento to external Windows Database Server using Windows Azure

  - by Kevin H

  "I tried to make this easy to read through" I am using Ubuntu 12.04 LTS for Magento and installed these commands onto the system: sudo apt-get install apache2 sudo apt-get install php5 libapache2-mod-php5 sudo apt-get install php5-mysql sudo apt-get install php5-curl php5-mcrypt php5-gd php5-common sudo apt-get install php5-gd I used Windows Server 2008 R2 August 2012 for Mysql Server For a reference, I used http://www.windowsazure.com/en-us/manage/windows/common-tasks/install-mysql/ When the server was setup, I added an empty disk to it Then, I added endpoints 3306 Next I accessed the server remotely After that, I formatted the empty disk and was inserted as F: Next I downloaded Mysql from http://*.mysql.com version Windows (x86, 64-bit), MSI Installer 5.5.28 In the installation process, I used these settings: Typical Setup - Clicked Next, install, next Chose Detailed Configuration - Clicked next Chose Dedicated MySQL Server Machine - Clicked Next Chose Transactional Database Only - Clicked Next Chose the "F:" Drive - Clicked Next Chose Online Transactional Processing (OLTP) - Clicked Next For Networking Options, I checkmarked 'Enable TCP/IP Networking" 'Add firewall exception for this port' 'Enable Strict Mode' - Clicked Next Chose Standard Character Set - Clicked Next For Windows Options, I checkedmarked 'Install as Window Service" 'Launch the MySQL Server automatically' 'Include Bin Directory in Windows PATH - Clicked Next For Security Options, I checkmarked 'Modify Security Settings' and set root password - Clicked Next Finally clicked Execute and Finish These are the Firewall Setting that I set I clicked inbound rules Properties Scope Allow IP Address and used the internal Address for Magento Server Clicked Apply and exited Next, I opened up MySQL 5.x Command Line Client Entered Root Password Then entered these commands mysql create database magento; mysql Create user magentouser identified by 'password'; mysql Grant select, insert, create, alter, update, delete, lock tables on magento.* to magentouser mysql exit Finally, I opened up the Magento Downloader Magento validation has approved all PHP version is right.

Also, I have tryed to setup mysql on independant Linux Server but kept getting errors. When, I found the solution. Wouldn't work, so I decided to try Windows. These is the questions, I have been asking and researching to debug this issue Is it because I am using Linux for magento and Windows for Database. I have had no luck in finding a reason why this wouldn't work There must be something, I am missing I also researched the difference between linux sql databases and windows sql databases but have not come to conclusion, if installing Mysql on windows would make a difference in syntax and coding. I have spent a lot of time looking into this and need some help with direction on how to complete my project. Any type of help would be appreciated.

• Building an SSL server farm

  - by dan

  I'm interested in building the the architecture in the article referenced below. I currently have a modestly-priced layer-4 load balancer and my application servers are the SSL endpoints. I want to put an SSL server farm in between my load balancer and my app servers. Then I will put another inexpensive load balancer between the SSL farm and my app servers, to do layer-7 routing. My web application has a fairly high amount of consumer traffic, that 6 servers can handle at about 50% capacity. Additionally, I have infrastructure traffic that is several orders of magnitude heavier than my consumer traffic. This is data coming in from all over the world that must integrate with my web application in real time. In total I have 18 app servers to handle all the traffic, plus 6 database servers. I will be adding 6 more app servers over the next 2 weeks and another 6 the 2 weeks after that. Conservatively, I estimate I will need to scale to 120 servers by the end of the year. My motivation right now is to separate the consumer traffic from the infrastructure traffic. The consumer traffic is higher priority than the infrastructure traffic and I cannot allow a stampede on the infrastructure side to take down my consumer-facing servers. Having a website that is always up is the top priority. However if there is a failure in one of the consumer app servers, I want to route that traffic to the servers designated for infrastructure traffic. The complication is that all the traffic is addressed using the same hostname and is nearly 100% https. The only way in my case to distinguish infrastructure from consumer traffic is by URL (poor architecture I inherited), so I need a layer 7 load balancer to be able to route. However for that to work I need either a fancy hardware-based SSL terminator or an SSL server farm as described above. Because my user base is rapidly scaling, I worry that if I go down the hardware path it will become very expensive very fast, especially since I will need 4 of everything for high availability (2 identical setups in 2 facilities). Meanwhile, the above diagram seems very flexible and more horizontally scalable. Has anyone built this before? Are there pre-built configurations? What considerations should I make and what software should I use (I've heard of people using apache with mod-ssl, nginx, and stunnel)? Also, when does it make sense to buy an expensive load balancer vs building an SSL server farm? http://1wt.eu/articles/2006_lb/index_05.html

• Complete machine freezes...at a loss

  - by user28818

  Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

• Nginx Rewrite Rule For File Within Folder Not Working

  - by user3620111

  Good evening everyone or possible early morning if you are in my neck of the woods. My problem seems trivial but after several hours of testing, researching and fiddling I can't seem to get this simple nginx rewrite function to work. There are several rewrites we need, some will have multiple parameters but I cant even get this simple 1 parameter current url to alter at all to the desired. Current: website.com/public/viewpost.php?id=post-title Desired: website.com/public/post/post-title Can someone kindly point me to as what I have done wrong, I am baffled / very tired... For testing purposes before we launch we were just using a simple port on the server. Here is that section. # Listen on port 7774 for dev test server { listen 7774; server_name localhost; root /usr/share/nginx/html/paa; index index.php home.php index.html index.htm /public/index.php; location ~* /uploads/.*\.php$ { if ($request_uri ~* (^\/|\.jpg|\.png|\.gif)$ ) { break; } return 444; } location ~ \.php$ { try_files $uri @rewrite =404; fastcgi_index index.php; include fastcgi_params; fastcgi_pass php5-fpm-sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_intercept_errors on; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location @rewrite { rewrite ^/viewpost.php$ /post/$arg_id? permanent; } } I have tried countless attempts such as above @rewrite and simpler: location / { rewrite ^/post/(.*)$ /viewpost.php?id=$1 last; } location ~ \.php$ { try_files $uri =404; fastcgi_index index.php; include fastcgi_params; fastcgi_pass php5-fpm-sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_intercept_errors on; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } I can not seem to get anything to work at all, I have tried changing the location tried multiple rules... Please tell me what I have done wrong. Pause for facepalm [relocated from stack overflow as per mod suggestion]

• Initial Review - Mastering Unreal Technology I: Introduction to Level Design with Unreal Engine 3

  - by Matt Christian

  Recently I purchased 3 large volumes on using the Unreal 3 Engine to create levels and custom games.  This past weekend I cracked the spine of the first and started reading.  Here are my early impressions (I'm ~250 pages into it, with appendices it's about 900). Pros Interestingly, the book starts with an overview of the Unreal engines leading up to Unreal 3 (including Gears of War) and follows with some discussion on planning a mod and what goes into the game development process.  This is nice for an intro to the book and is much preferred rather than a simple chapter detailing what is on the included CD, how to install and setup UnrealEd, etc...  While the chapter on Unreal history and planning can be considered 'fluff', it's much less 'fluffy' than most books provide. I need to mention one thing here that is pretty crucial in the way I'm going to continue reviewing this book.  Most technical books like this are used as a shelf reference; as a thick volume you use for looking up techniques every now and again.  Even so, I prefer reading from cover to cover, including chapters I may already be knowledgable on (I'm sure this is typical for most people).  If there was a chapter on installing UnrealEd (the previously mentioned 'fluff'), I would probably force myself to read it, even though I've installed the game and engine multiple times on different systems. Chapter 3 is where we really get to the introduction piece of UnrealEd, creating your first basic level.  This large chapter details creating two small rooms, adding static meshes, adding lighting, creating and adding particle emitters, creating a door that animates with Unreal Matinee and Kismet, static meshes with physics, and other little additions to make your level look less beginner.  This really is a chapter that overviews the entire rest of the book, as each chapter following details the creation and intermediate usages of Static Meshes, Materials, Lighting, etc... One other very nice part to this book is the way the tutorials are setup.  Each tutorial builds off the previous and all are step-by-step.  If you haven't completed one yet, you can find all the starting files on the CD that comes with the book. Cons While the description of the overview chapter (Chapter 3) is fresh in your mind, let me start the cons by saying this chapter is setup extremely confusing for the noob.  At one point, you end up creating a door mesh and setting it up as a InteropMesh so that it is ready to be animated, only to switch to particles and spend a good portion of time working on a different piece of the level.  Yes, this is actually how I develop my levels (jumping back and forth), though it's very odd for a book to jump out of sequence. The next item might be a positive or a negative depending on your skill level with UnrealEd.  Most of the introduction to the editor layout is found in one of the Appendices instead of before Chapter 3.  For new readers, this might lead to confusion as Appendix A would typically be read between Chapter 2 and 3.  However, this is a positive for those with some experience in UnrealEd as they don't have to force themselves through a 'learn every editor button' chapter.  I'm listing this in the Cons section as the book is 'Introduction to...' and is probably going to be directed toward a lot of very beginner developers. Finally, there's a lack of general description to a lot of the underlying engine and what each piece in UnrealEd is or does.  Sometimes you'll be performing Tutorial after Tutorial with barely a paragraph in between describing ANY of what you've just done.  Tutorial 1.1 Step 6 says to press Button X, so you do.  But why?  This is in part a problem with the structure of the tutorials rather than the content of the book.  Since the tutorials are so focused on a step-by-step (or procedural) description of a process, you learn the process and not why you're doing that.  For example, you might learn how to size a material to a surface, but will only learn what buttons to press and not what each one does. This becomes extremely apparent in the chapter on Static Meshes as most of the chapter is spent in 3D Studio Max.  Since there are books on 3DSM and modelling, the book really only tells you the steps and says to go grab a book on modelling if you're really interested in 3DSM.  Again, I've learned the process to develop my own meshes in 3DSM, but I don't know the why behind the steps. Conclusion So far the book is very good though I would have a hard time recommending it to a complete beginner.  I would suggest anyone looking at this book (obviously including the other 2, more advanced volumes) to pick up a copy of UDK or Unreal 3 (available online or via download services such as Steam) and watch some online tutorials and play with it first.  You'll find plenty of online videos available that were created by the authors and may suit as a better introduction to the editor.

• Intel Centrino Wireless-N 1000 Again ! Ubuntu 13.04 x64

  - by vafa

  First I have to say that I tried everything written about this concept. The problem is that it stops working randomly in 3 main forms : 1 - sometimes it disconnect from wireless network and reconnect automatically 2 - sometimes it disconnect and wont connect no matter what (needs reboot) 3 - some times it's still connected but cannot ping or surf or whatever. I already tried disabling N mod using these commands : sudo modprobe -r iwlwifi modprobe iwlwifi 11n_disable=1 (or 0, whatever) it didn't help . these are the results of lspci, sudo lshw -C network, ifconfig, iwconfig, rfkill list when it disconnected and didn't connect till reboot : ifconfig : eth0 Link encap:Ethernet HWaddr c8:0a:a9:34:65:77 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX

• Finding edge and corner values of an image in matlab

  - by James

  Hi, this problem links to two other questions i've asked on here. I am tracing the outline of an image and plotting this to a dxf file. I would like to use the bwboundaries function to find the coordinates of the edges of the image, find the corner coordinates using the cornermetric function and then remove any edge coordinates that are not a corner. The important thing I need to be able to do is keep the order of the corner elements obtained from bwboundaries, so that the section traces properly. The dxf function I have that draws from the coordinates draws lines between coordinates that are next to each other, so the line has to be drawn "around" the section rather than straight between the corner points. The reason I am doing this is because there are less coordinates obtained this way, so it is easier to amend the dxf file (as there are less points to manipulate). The code I have so far is: %# Shape to be traced bw = zeros(200); bw(20:40,20:180) = 1; bw(20:180,90:110) = 1; bw(140:180,20:185) = 1; %# Boundary Finding Section [Boundary] = bwboundaries(bw); %Traces the boundary of each section figure, imshow(bw); hold on; colors=['b' 'g' 'r' 'c' 'm' 'y']; for k=1:length(Boundary) perim = Boundary{k}; %Obtains perimeter coordinates (as a 2D matrix) from the cell array cidx = mod(k,length(colors))+1;% Obtains colours for the plot plot(perim(:,2), perim(:,1),... colors(cidx),'LineWidth',2); end Coordmat = cell2mat(Boundary) %Converts the traced regions to a matrix X = Coordmat(:,1) Y = Coordmat(:,2) % This gives the edge coordinates in matrix form %% Corner Finding Section (from Jonas' answer to a previous question %# get corners cornerProbability = cornermetric(bw); cornerIdx = find(cornerProbability==max(cornerProbability(:))); %# Label the image. bwlabel puts 1 for the first feature, 2 for the second, etc. %# Since concave corners are placed just outside the feature, grow the features %# a little before labeling bw2 = imdilate(bw,ones(3)); labeledImage = bwlabel(bw2); %# read the feature number associated with the corner cornerLabels = labeledImage(cornerIdx); %# find all corners that are associated with feature 1 corners_1 = cornerIdx(cornerLabels==1) [Xcorners, Ycorners] = ind2sub(200,corners_1) % Convert subscripts The code I have is, to give a matrix Xfin for the final x coordinates (which are on the edge AND at a corner. Xfin = zeros(length(X),1) for i = Xcorners XFin(i) = Xcorners if i~= Xcorners XFin(i) = [] end end However, this does not work correctly, because the values in the solution are sorted into order, and only one of each value remains. As I said, I would like the corner elements to be in the same order as obtained from bwboundaries, to allow the image to trace properly. Thanks

• Processing an Integer Buried in a String in XSL

  - by justkt

  I have a stored time value which is of the format H:mm:ss. The hours may be any value from 0 up through several days. This data is sent in an XML tag and processed by XSL to be displayed. The display that I want is of the format: D days, HH:mm:ss (hours/minutes) Where the last tag shows hours if HH is greater than 0, minutes if it is 0. Given the original HH, which may be more than 24, I know I need the floor of HH / 24 to get the days value. Then the original HH % 24 gives me the leftover hours. I have also handled the minutes and hours question using xsl:when and xsl:if. It's getting days and hours from the hours value that has me stumped. EDIT So far, I'm looking at doing the following: Variable declaration <xsl:variable name="time"><xsl:value-of select="time" /><xsl:variable> <xsl:variable name="days"><xsl:value-of select="floor(substring-before(time, ':') / 24)" /></xsl:variable> <xsl:variable name="hours"><xsl:value-of select="substring-before(time, ':') mod 24" /></xsl:variable> <xsl:variable name="minutes"><xsl:value-of select="substring-after(time, ':')" /></xsl:variable> Use <xsl:if test="$days > 0"> <xsl:value-of select="$days" /> days </xsl:if> <xsl:value-of select="$hours" />:<xsl:value-of select="$minutes" /> <xsl:choose> <xsl:when test="$hours > 0"> hour<xsl:if test="$hours > 1">s</xsl:if> </xsl:when> <xsl:otherwise> minute<xsl:if test="$minute != '01:00'">s</xsl:if> </xsl:otherwise> </xsl:choose> And for clarification, a sample time would be <time>26:15:00</time> for 1 day 2:15 hours.

• Becoming a professional programmer / software engineer

  - by Matt

  This isn't strictly about programming, more about being a programmer, so I'm sorry if its not the right kind of question to ask on this forum (mod, please delete if it isn't) I'm a computer tech in the US Army, and once I'm out I'll have eight years on the job. I'm about to start a degree through an online school (the only way I can get the army to pay for it while I'm still in), and I'm seriously looking at getting a computer science degree. I'm great with computers. I can take one apart and put it back together with my eyes closed. I'm A+ and Network+ certified and I'm getting a couple other CompTIA certs before I get out. I can work Windows as well as anyone on this planet and I'm not terrible with Linux. A job in computers is something I've always wanted. But, aside from being a computer technician, it seems that every job in the field requires programming ability. I like programming as a hobby. I programmed TI BASIC in high school and I'm teaching myself Python, but that's as far as my experience goes. That sort of brings me to my questions: I've always heard that the first language is the most difficult, and once you learn it well then all the others sort of fall into place for you. Is that true? Like, if I spend the next eight months mastering Python, will I pretty much be able to pick up at least fair proficiency in any other OO language within a month of studying it or whatever? How easy is it to burn out? the biggest thing I'm afraid of is just burning out on programming. I can go all day long if I'm programming strictly for my own personal desire, but I can imagine it being really easy to burn out after a few years of programming to deadlines and certain specifications. Especially if its a big project involving a dozen different designers. From what I told you about myself, would I already be qualified to work as a regular technician (geek squad type or maybe running a computer repair shop). Is Python a good base to learn from? I've heard that it makes you hate other languages because they feel more convoluted when learning, but also that its a great beginner language. If you're a professional programmer, did you have any of the same fears? Would you recommend that I stick to computer repair and Python rather than try to get into corporate programming? (just from what you've read in this thread, anyway) Thanks for taking the time to read all this and answer (if you did)

• Linux Device Driver: Symbol "memcpy" not found

  - by Hinton

  Hello, I'm trying to write a Linux device driver. I've got it to work really well, until I tried to use "memcpy". I don't even get a compiler error, when I "make" it just warns me: WARNING: "memcpy" [/root/homedir/sv/main.ko] undefined! OK and when I try to load via insmod, I get on the console: insmod: error inserting './main.ko': -1 Unknown symbol in module and on dmesg: main: Unknown symbol memcpy (err 0) I include the following: #include <linux/module.h> #include <linux/moduleparam.h> #include <linux/init.h> #include <linux/kernel.h> /* printk() */ #include <linux/slab.h> /* kmalloc() */ #include <linux/fs.h> /* everything... */ #include <linux/errno.h> /* error codes */ #include <linux/types.h> /* size_t */ #include <linux/fcntl.h> /* O_ACCMODE */ #include <linux/cdev.h> #include <asm/system.h> /* cli(), *_flags */ #include <asm/uaccess.h> /* copy_*_user */ The function using memcpy: static int dc_copy_to_user(char __user *buf, size_t count, loff_t *f_pos, struct sv_data_dev *dev) { char data[MAX_KEYLEN]; size_t i = 0; /* Copy the bulk as long as there are 10 more bytes to copy */ while (i < (count + MAX_KEYLEN)) { memcpy(data, &dev->data[*f_pos + i], MAX_KEYLEN); ec_block(dev->key, data, MAX_KEYLEN); if (copy_to_user(&buf[i], data, MAX_KEYLEN)) { return -EFAULT; } i += MAX_KEYLEN; } return 0; } Could someone help me?

• Would someone mind giving suggestions for this new assembly language?

  - by Noctis Skytower

  Greetings! Last semester in college, my teacher in the Computer Languages class taught us the esoteric language named Whitespace. In the interest of learning the language better with a very busy schedule (midterms), I wrote an interpreter and assembler in Python. An assembly language was designed to facilitate writing programs easily, and a sample program was written with the given assembly mnemonics. Now that it is summer, a new project has begun with the objective being to rewrite the interpreter and assembler for Whitespace 0.3, with further developments coming afterwards. Since there is so much extra time than before to work on its design, you are presented here with an outline that provides a revised set of mnemonics for the assembly language. This post is marked as a wiki for their discussion. Have you ever had any experience with assembly languages in the past? Were there some instructions that you thought should have been renamed to something different? Did you find yourself thinking outside the box and with a different paradigm than in which the mnemonics were named? If you can answer yes to any of those questions, you are most welcome here. Subjective answers are appreciated! hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo save Store load Retrieve L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack Question: How would you redesign, rewrite, or rename the previous mnemonics and for what reasons?

• RNDC fails: permission denied

  - by pawz

  Named works great. It creates a pid in /var/run/named/named.pid as expected. It is listening on port 953 as shown by the log: Apr 20 14:42:38 guchuko named[9115]: command channel listening on 127.0.0.1#953 But whenever I try to run "rndc reload" I get: rndc: 'reload' failed: permission denied What file is it being denied permission to ? It doesn't log anything so I don't know why it's not working. I've compiled bind 9.4-ESV-R1 from source and I've patched it with the mysql mod. my named.conf: options { directory "/var/bind"; forwarders { 203.82.213.101; 203.188.144.1; }; listen-on-v6 { none; }; listen-on { 127.0.0.1; 192.168.0.6; }; pid-file "/var/run/named/named.pid"; }; logging { channel simple_log { file "/var/log/named.log" versions 3 size 5m; severity debug 5; print-time yes; print-severity yes; print-category yes; }; category default { simple_log; }; }; zone "."

• Wrong sessionID being used in callback, but only on one particular computer

  - by user210119

  I am writing a Python/Django web application that uses OAuth (for the TwitterAPI, not that it should matter). I am storing a session ID in my login function, and then after using OAuth to get the user's token, I try to retrieve the sessionID in my callback function. The callback function then always fails(throws an exception) because it can't find the OAuth token in the session. Through the debugger, I am able to determine that the session ID that the server is using is incorrect - it does not match the session ID that was stored in the login function. It's therefore unsurprising that the Oauth tokens were not there. The session that appears in the callback was the same one each time (until I tried deleting it - see "things I've tried below"), and it started out as an old session, with some data in it that is from a different django app running on the same server that I hadn't touched in a couple weeks. Here's the kicker: everything I described is an issue only on our production server, and only when connecting to it from my computer. Let me clarify: this only happens with my particular laptop. I can connect to the app just fine from someone else's computer. Other people cannot connect with their accounts on my computer. Furthmore, I can connect just fine to the app when it is running on my localhost using the built-in django webserver, just not to the production server. My setup: my server and local box are running= Django 1.2.0 and Python 2.6.5. My local box is running Snow Leopard and the Django webserver, the server is running Ubuntu, Apache2, and mod-wsgi. For sessions, I am using Django's default session backend (DB). Things I have tried, all to no avail: logging in with a different account, including new accounts that have never OAuthed to this app before Clearing cookies, using incognito mode, using a different web browser on my same computer. Each time, upon inspecting my cookies, the sessionID matched the sessionID in the login function and was different from the sessionID in the callback. deleting the session in the database that appears in the callback function, (the one that appeared to be old data). The callback function still fails, and the sessionID it appears to be using is now a new one using a different session backend (DB-cache, flat file, etc...) restarting the server, my computer, etc. My first question on StackOverflow, so bear with me if I didn't quite follow local conventions. I am just at a loss as to what to even look for - what are the things that could possibly be causing sessions to not work on my particular computer, and (so far!) only my particular computer?

• How to setup Lucene/Solr for a B2B web app?

  - by Bill Paetzke

  Given: 1 database per client (business customer) 5000 clients Clients have between 2 to 2000 users (avg is ~100 users/client) 100k to 10 million records per database Users need to search those records often (it's the best way to navigate their data) Possibly relevant info: Several new clients each week (any time during business hours) Multiple web servers and database servers (users can login via any web server) Let's stay agnostic of language or sql brand, since Lucene (and Solr) have a breadth of support For Example: Joel Spolsky said in Podcast #11 that his hosted web app product, FogBugz On-Demand, uses Lucene. He has thousands of on-demand clients. And each client gets their own database. They use an index per client and store it in the client's database. I'm not sure on the details. And I'm not sure if this is a serious mod to Lucene. The Question: How would you setup Lucene search so that each client can only search within its database? How would you setup the index(es)? Where do you store the index(es)? Would you need to add a filter to all search queries? If a client cancelled, how would you delete their (part of the) index? (this may be trivial--not sure yet) Possible Solutions: Make an index for each client (database) Pro: Search is faster (than one-index-for-all method). Indices are relative to the size of the client's data. Con: I'm not sure what this entails, nor do I know if this is beyond Lucene's scope. Have a single, gigantic index with a database_name field. Always include database_name as a filter. Pro: Not sure. Maybe good for tech support or billing dept to search all databases for info. Con: Search is slower (than index-per-client method). Flawed security if query filter removed. One last thing: I would also accept an answer that uses Solr (the extension of Lucene). Perhaps it's better suited for this problem. Not sure.

• [C] Programming problem: Storing values of an array in one variable

  - by OldMacDonald

  Hello, I am trying to use md5 code to calculate checksums of file. Now the given function prints out the (previously calculated) checksum on screen, but I want to store it in a variable, to be able to compare it later on. I guess the main problem is that I want to store the content of an array in one variable. How can I manage that? Probably this is a very stupid question, but maybe somone can help. Below is the function to print out the value. I want to modify it to store the result in one variable. static void MDPrint (mdContext) MD5_CTX *mdContext; { int i; for (i = 0; i < 16; i++) { printf ("%02x", mdContext->digest[i]); } // end of for } // end of function For reasons of completeness the used struct: /* typedef a 32 bit type */ typedef unsigned long int UINT4; /* Data structure for MD5 (Message Digest) computation */ typedef struct { UINT4 i[2]; /* number of _bits_ handled mod 2^64 */ UINT4 buf[4]; /* scratch buffer */ unsigned char in[64]; /* input buffer */ unsigned char digest[16]; /* actual digest after MD5Final call */ } MD5_CTX; and the used function to calculate the checksum: static int MDFile (filename) char *filename; { FILE *inFile = fopen (filename, "rb"); MD5_CTX mdContext; int bytes; unsigned char data[1024]; if (inFile == NULL) { printf ("%s can't be opened.\n", filename); return -1; } // end of if MD5Init (&mdContext); while ((bytes = fread (data, 1, 1024, inFile)) != 0) MD5Update (&mdContext, data, bytes); MD5Final (&mdContext); MDPrint (&mdContext); printf (" %s\n", filename); fclose (inFile); return 0; }

• Unable to use getInt() but able to use getString() for a sqlite database

  - by mwrazam

  I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more

• Does likewise-open > version 5.4 contain CIFS support?

  - by Ben Andken

  I'm trying to get the CIFS server working in likewise-open. I've found this set of instructions and everything seems to work until I try to connect ([url]http://www.likewise.com/resources/documentation_library/manuals/cifs/likewise-cifs-smb-file-server-guide.html#id2765992):[/url] 1.6. Build and Configure a Standalone Likewise-CIFS Server This section demonstrates how to build and configure a standalone instance of Likewise-CIFS from the command line. The following procedure assumes that you want to set up Likewise-CIFS on a Linux server to share files with Windows computers in a network without Active Directory. This procedure also assumes you know how to build Linux applications from their source code and then install them. Download Likewise-CIFS from its open source git location: $ git clone git://git.likewiseopen.org/ Download, build, and install the following tools. The tools listed are known to work, but earlier or later versions might work as well. Also, instead of downloading the tools, you might be able to install them on your platform with apt-get or some other means. http://ftp.gnu.org/gnu/autoconf/autoconf-2.65.tar.gz http://ftp.gnu.org/gnu/automake/automake-1.9.6.tar.gz http://ftp.gnu.org/gnu/libtool/libtool-2.2.6a.tar.gz http://pkgconfig.freedesktop.org/releases/pkg-config-0.23.tar.gz gcc --version 3.x or greater Build Likewise-CIFS: $ cd likewise-open $ build/mkcomp --debug all Install Likewise-CIFS: $ sudo su $ cd staging/install-root $ tar cf - . | (cd / && tar xvf -) Make sure Samba is not running: $ /etc/init.d/smb stop Make sure SELinux is either disabled or set to permissive. Make sure the ports required by Likewise are open. For a list of ports that Likewise uses, see the Likewise Open Installation and Administration Guide. Configure Likewise Open: $ /etc/init.d/lwsmd start $ for i in /etc/likewise/*.reg; do /opt/likewise/bin/lwregshell upgrade $i; done $ /etc/init.d/lwsmd stop $ /etc/init.d/lwsmd start $ /opt/likewise/bin/lwsm start srvsvc $ /opt/likewise/bin/domainjoin-cli configure --enable nsswitch Add a user account to the local Likewise provider database. In the following example, substitute the account name that you want for newuser. $ /opt/likewise/bin/lw-add-user --home /home/newuser --shell /bin/bash newuser Successfully added user newuser Enable the user and set the password: $ /opt/likewise/bin/lw-mod-user --enable-user --set-password newuser New Password: ********** Successfully modified user newuser Look up new user's identity as follows. Substitute the value from the command hostname -s for the hostname. Keep in mind that Likewise truncates a hostname longer than 15 characters to the first 15 characters of the string. % id hostname\\newuser uid=2000(HOSTNAME\newuser) gid=1800(HOSTNAME\Likewise Users) groups=1800(HOSTNAME\Likewise Users) context=system_u:system_r:unconfined_t:s0 Make a CIFS directory for the user: mkdir /lwcifs/newuser chown 2000:1800 /lwcifs/newuser From a Windows computer, map the Likewise-CIFS drive share: Computer->Map Network Drive... Folder: \\IP_hostname\c$ Click "Finish" Username: hostname\newuser Password: user_password The last step fails when I try to connect. I've tried with Windows XP Pro and Windows 7 Pro. The rest of the directions only appear to work for version 5.4 (the one that shipped with 10.04). For 12.04, version 6.1 is the only one available and it doesn't appear to have the srvsvc module mentioned in these instructions. Is CIFS support dropped in the 6.1 version of likewise-open?

• Wireless AAA for a small, bandwidth-limited hotel.

  - by Anthony Hiscox

  We (the tech I work with and myself) live in a remote northern town where Internet access is somewhat of a luxury, and bandwidth is quite limited. Here, overage charges ranging from few hundreds, to few thousands of dollars a month, is not uncommon. I myself incur regular monthly charges just through my regular Internet usage at home (I am allowed 10G for $60CAD!) As part of my work, I have found myself involved with several hotels that are feeling this. I know that I can come up with something to solve this problem, but I am relatively new to system administration and I don't want my dreams to overcome reality. So, I pass these ideas on to you, those with much more experience than I, in hopes you will share some of your thoughts and concerns. This system must be cost effective, yes the charges are high here, but the trust in technology is the lowest I've ever seen. Must be capable of helping client reduce their usage (squid) Allow a limited (throughput and total usage) amount of free Internet, as this is often franchise policy. Allow a user to track their bandwidth usage Allow (optional) higher speed and/or usage for an additional charge. This fee can be obtained at the front desk on checkout and should not require the use of PayPal or Credit Card. Unfortunately some franchises have ridiculous policies that require the use of a third party remote service to authenticate guests to your network. This means WPA is out, and it also means that I do not auth before Internet usage, that will be their job. However, I do require the ABILITY to perform authentication for Internet access if a hotel does not have this policy. I will still have to track bandwidth (under a guest account by default) and provide the same limiting, however the guest often will require a complete 'unlimited' access, in terms of existence, not throughput. Provide firewalling capabilities for hotels that have nothing, Office, and Guest network segregation (some of these guys are running their office on the guest network, with no encryption, and a simple TOS to get on!) Prevent guests from connecting to other guests, however provide a means to allow this to happen. IE. Each guest connects to a page and allows the other guest, this writes a iptables rule (with python-netfilter) and allows two rooms to play a game, for instance. My thoughts on how to implement this. One decent box (we'll call it a router now) with a lot of ram, and 3 NIC's: Internet Office Guests (AP's + In Room Ethernet) Router Firewall Rules Guest can talk to router only, through which they are routed to where they need to go, including Internet services. Office can be used to bridge Office to Internet if an existing solution is not in place, otherwise, it simply works for a network accessible web (webmin+python-webmin?) interface. Router Software: OpenVZ provides virtualization for a few services I don't really trust. Squid, FreeRADIUS and Apache. The only service directly accessible to guests is Apache. Apache has mod_wsgi and django, because I can write quickly using django and my needs are low. It also potentially has the FreeRADIUS mod, but there seems to be some caveats with this. Firewall rules are handled on the router with iptables. Webmin (or a custom django app maybe) provides abstracted control over any features that the staff may need to access. Python, if you haven't guessed it's the language I feel most comfortable in, and I use it for almost everything. And finally, has this been done, is it a overly massive project not worth taking on for one guy, and/or is there some tools I'm missing that could be making my life easier? For the record, I am fairly good with Python, but not very familiar with many other languages (I can struggle through PHP, it's a cosmetic issue there). I am also an avid linux user, and comfortable with config files and command line. Thank you for your time, I look forward to reading your responses. Edit: My apologies if this is not a Q&A in the sense that some were expecting, I'm just looking for ideas and to make sure I'm not trying to do something that's been done. I'm looking at pfSense now as a possible start for what I need.

• Disable error_log. Error_log flooding

  - by user36646

  Hello, i got an webserver running and old version of gambio (xt:commerce fork). The error_log in the dir over the public_html is flooding with errors. About 30mb in 15min. How can I disable this log? I can't fix all the errors. Here are a few examples of the errors: [warn] mod_fcgid: stderr: PHP Notice: Undefined variable: key in /usr/www/users/foo//includes/classes/class.inputfilter.php on line 98 [warn] mod_fcgid: stderr: PHP Notice: Undefined index: in /usr/www/users/foo/templ [warn] mod_fcgid: stderr: in /usr/www/users/foo/templates/gambio/source/inc/xtc_show_category_sectionc.inc.php on line 47 They are all errors of: "mod_fcgid: stderr". I tried to grep "error_log" and "error_report" in the public html dir, but i did not find anything.

• iptables 1.4 and passive FTP on custom port

  - by Cracky

  after the upgrade from debian squeeze to wheezy I've got a problem with passive FTP connection. I could narrow it to be iptables related, as I could connect via FTP w/o problems after adding my IP to the iptables ACCEPT rule. Before the upgrade I was able just to do modprobe nf_conntract_ftp ports=21332 and adding iptables -A THRU -p tcp --dport 21332 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT now..it doesn't help anymore. The INPUT rule is being triggered as I can see in the counter, but the directory listing is the last thing it does. Setting up a passive-port range is the last thing I want to do, I dislike open ports. I also tried the trick with helper mod by adding following rule before the actual rule for 21332 iptables -A THRU -p tcp -i eth0 --dport 21332 -m state --state NEW -m helper --helper ftp-21332 -j ACCEPT but it doesn't help and is even not being triggered according to counter. The rule in the next line (w/o helper) is being triggered.. here some info: # iptables --version iptables v1.4.14 # lsmod |grep nf_ nf_nat_ftp 12460 0 nf_nat 18242 1 nf_nat_ftp nf_conntrack_ftp 12605 1 nf_nat_ftp nf_conntrack_ipv4 14078 32 nf_nat nf_defrag_ipv4 12483 1 nf_conntrack_ipv4 nf_conntrack 52720 7 xt_state,nf_conntrack_ipv4,xt_conntrack,nf_conntrack_ftp,nf_nat,nf_nat_ftp,xt_helper # uname -a Linux loki 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux # iptables-save # Generated by iptables-save v1.4.14 on Sun Jun 30 03:54:28 2013 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :BLACKLIST - [0:0] :LOGDROP - [0:0] :SPAM - [0:0] :THRU - [0:0] :WEB - [0:0] :fail2ban-dovecot-pop3imap - [0:0] :fail2ban-pureftpd - [0:0] :fail2ban-ssh - [0:0] -A INPUT -p tcp -m multiport --dports 110,995,143,993 -j fail2ban-dovecot-pop3imap -A INPUT -p tcp -m multiport --dports 21,21332 -j fail2ban-pureftpd -A INPUT -p tcp -m multiport --dports 22 -j fail2ban-ssh -A INPUT -p tcp -m multiport --dports 110,995,143,993 -j fail2ban-dovecot-pop3imap -A INPUT -i lo -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --tcp-flags FIN,SYN,RST,PSH,ACK,URG NONE -j DROP -A INPUT -i eth0 -p tcp -m tcp --tcp-flags FIN,SYN FIN,SYN -j DROP -A INPUT -i eth0 -p tcp -m tcp --tcp-flags SYN,RST SYN,RST -j DROP -A INPUT -i eth0 -p tcp -m tcp --tcp-flags FIN,RST FIN,RST -j DROP -A INPUT -i eth0 -p tcp -m tcp --tcp-flags FIN,ACK FIN -j DROP -A INPUT -i eth0 -p tcp -m tcp --tcp-flags ACK,URG URG -j DROP -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -j BLACKLIST -A INPUT -j THRU -A INPUT -j LOGDROP -A OUTPUT -j ACCEPT -A OUTPUT -s 93.223.38.223/32 -j ACCEPT -A BLACKLIST -s 38.113.165.0/24 -j LOGDROP -A BLACKLIST -s 202.177.216.0/24 -j LOGDROP -A BLACKLIST -s 130.117.190.0/24 -j LOGDROP -A BLACKLIST -s 117.79.92.0/24 -j LOGDROP -A BLACKLIST -s 72.47.228.0/24 -j LOGDROP -A BLACKLIST -s 195.200.70.0/24 -j LOGDROP -A BLACKLIST -s 195.200.71.0/24 -j LOGDROP -A LOGDROP -m limit --limit 5/sec -j LOG --log-prefix drop_packet_ --log-level 7 -A LOGDROP -p tcp -m tcp --dport 25 -m limit --limit 2/sec -j LOG --log-prefix spam_blacklist --log-level 7 -A LOGDROP -p tcp -m tcp --dport 80 -m limit --limit 2/sec -j LOG --log-prefix web_blacklist --log-level 7 -A LOGDROP -p tcp -m tcp --dport 22 -m limit --limit 2/sec -j LOG --log-prefix ssh_blacklist --log-level 7 -A LOGDROP -j REJECT --reject-with icmp-host-prohibited -A THRU -p icmp -m limit --limit 1/sec -m icmp --icmp-type 8 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 25 -j ACCEPT -A THRU -i eth0 -p udp -m udp --dport 53 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 110 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 143 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 465 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 585 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 993 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 995 -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 2008 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 10011 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 21332 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT -A THRU -i eth0 -p tcp -m tcp --dport 30033 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT -A fail2ban-dovecot-pop3imap -j RETURN -A fail2ban-dovecot-pop3imap -j RETURN -A fail2ban-pureftpd -j RETURN -A fail2ban-pureftpd -j RETURN -A fail2ban-ssh -j RETURN -A fail2ban-ssh -j RETURN COMMIT # Completed on Sun Jun 30 03:54:28 2013 So, as I said, I have no problems with connecting when adding my IP to go through..but that's not a solution as noone except me can connect anymore~ If someone got an idea what the problem is, please help me! Thanks Cracky
