  • Finding a private (NAT) host's IP using historic destination data

    - by l0c0b0x
    The issue: An unknown private (NAT) client is infected with malware and it's trying to access a Bot server at random times/dates. How we know about this: We receive bot traffic notices/alerts from REN-ISAC. Unfortunately, we don't receive those until the next day after it has happened. What they provide to us is: The source address (of the firewall) The destination addresses (it varies, but they're going to network subnet allocated to a German ISP) The source port (which varies--dynamic ports). Question: What would be the best approach to finding this internal host (historically) with a Cisco ASA as firewall? I'm guessing blocking anything to the destination address(es), and logging that type of traffic/access might allow me to find the source host, but I'm not sure which tool/command would be the most useful. I've seen Netflow thrown into a few responses when it comes to logging, but I'm confused with it's association of Logging, NAL, and nBAR, and how they relate to Netflow.

  • SQL Server stored procedure + set error message from the records of a table

    - by lucky
    Hello, My question is I have a table with the set of records. I am calling a stored procedure for some other purpose. But when ever it finds some duplicate records. It need to return as error message back to php. C1 C2 c3 abc 32 21.03.2010 def 35 04.04.2010 pqr 45 30.03.2010 abc 12 04.05.2010 xyz 56 01.03.2010 ghi 21 06.05.2010 def 47 17.02.2010 klm 93 04.03.2010 xyz 11 01.03.2010 For the above set it need to check for the records that has the same c1. The stored procedure should return as abc,def,xyz are duplicate. I tried something like this. This will not work it has more than 1 set of duplicate records. Please help me to enhance this to solve the purpose. SET @duplicate = (SELECT c1 FROM temp GROUP BY c1 HAVING count(c1) > 1) --Check for duplicate concession Nr. IF(len(@duplicate) > '1') BEGIN SET @error = @error + ' Duplicate C1 Number:- ' + @duplicate SET @errorcount = @errorcount + 1 END As this one type error I am checking for errorcount. IF @errorcount <> '0' BEGIN GOTO E_General_Error END -- If an error occurs, rollback and exit E_General_Error: PRINT 'Error' SET @error = @error IF @@error <> 0 SET @error = 'Database update failed' ROLLBACK TRANSACTION update_database RETURN END Now it is able to return Duplicate c1 number abc. If there are more than 1 problem comes. Thanks in advance!

  • setBit java method using bit shifting and hexadecimal code - question

    - by somewhat_confused
    I am having trouble understanding what is happening in the two lines with the 0xFF7F and the one below it. There is a link here that explains it to some degree. http://www.herongyang.com/java/Bit-String-Set-Bit-to-Byte-Array.html I don't know if 0xFF7FposBit) & oldByte) & 0x00FF are supposed to be 3 values 'AND'ed together or how this is supposed to be read. If anyone can clarify what is happening here a little better, I would greatly appreciate it. private static void setBit(byte[] data, final int pos, final int val) { int posByte = pos/8; int posBit = pos%8; byte oldByte = data[posByte]; oldByte = (byte) (((0xFF7F>>posBit) & oldByte) & 0x00FF); byte newByte = (byte) ((val<<(8-(posBit+1))) | oldByte); data[posByte] = newByte; } passed into this method as parameters from a selectBits method was setBit(out,i,val); out = is byte[] out = new byte[numOfBytes]; (numOfBytes can be 7 in this situation) i = which is number [57], the original number from the PC1 int array holding the 56-integers. val = which is the bit taken from the byte array from the getBit() method.

  • Why is music tagging software so inconsistent?

    - by Billy ONeal
    Hello :) A few years ago I spent an insane amount of time using the excellent Tag&Rename program. However, I find that for random, inexplicable reasons, some music tools simply disregard my tags, and drop or destroy the album art, or have strange handling around some characters. For example, "AC/DC" is poorly handled by most music players when I use Tag&Rename to write the tags. Is there a piece of software that works like Tag&Rename but is more compatible, or is there a way to ensure Tag&Rename writes more compatible tags?

  • start-stop-daemon quoted arguments misinterpreted

    - by Martin Westin
    Hi, I have been trying to make an init script using start-stop-daemon. I am stuck on the arguments to the daemon. I want to keep these in a variable at the top of the script but I can't get the quotations to filter down correctly. I'll use ls here so we don't have to look at binaries and arguments that most people wont know or care about. The end result I am looking for is for start-stop... to run ls -la "/folder with space/" DAEMON=/usr/bin/ls DAEMON_OPTS='-la "/folder with space/"' start-stop-daemon --start --make-pidfile --pidfile $PID --exec $DAEMON -- $DAEMON_OPTS Double escaping the options and trying innumerable variations of quotations do not help... Then they end up at the daemon they are always messed up. Enclosing $DAEMON_OPTS in quotes changes things... then they are seen as one since quote... never the right number though :) Echoing the command-line (start-stop...) prints exactly the right stuff to screen. But the daemon (the real one, not ls) complains about the wrong number of arguments. How do I specify a variable so that quotes inside it are brought along to the daemon correctly? Thanks, Martin

  • Intel RAID0 on Windows 8 not Displaying Correct Media Type

    - by kobaltz
    I have my primary C Drive which consists of 2 Intel 120GB SSD Drives in a RAID0. I have a clean install of Windows 8 Pro, latest MEI software, latest RST software, latest Intel Toolbox. Prior to this I had installed Windows 8 Pro as an upgrade. When I went into the Optimize Drives while in the Upgrade installation, it showed the Media Types as Solid State Drives. However, now since I am in a brand new install, it is showing the Media Type as Hard Disk Drive. I am worried about this because of the trim not working properly. Before when in the upgrade, it showed SSD as the media type and the Optimize option would perform a manual trim. Unfortunately, my search credentials on Google are so common to many other things (ie Raid0, SSD, Windows 8, Media Type) that all I am finding are useless topics. Before, (found on random site) it showed the Media Type as below

  • Nginx + PHP-FPM ignores no-cache headers

    - by Eric Winchell
    I'm using the following header on a php page. // Prevent page caching. header('Expires: Tue, 20 Oct 1981 05:00:00 GMT'); header('Cache-Control: no-store, no-cache, must-revalidate'); header('Cache-Control: post-check=0, pre-check=0', FALSE); header('Pragma: no-cache'); I'm also using a rand=999999999 (with a real random number) in the URLs. But pages are still being cached. Reload works, but first load is cached. Anyone know where I can change this?

  • Nested loops break out unexpectedly

    - by Metju
    Hi guys, I'm trying to create a sudoku game, for those that do not know what it is. You have a 9x9 box that needs to be filled with numbers from 1-9, every number must be unique in its row and column, and also in the 3x3 box it is found. I ended up doing loads of looping within a 2 dimensional array. But at some point it just stops, with no exceptions whatsoever, just breaks out and nothing happens, and it's not always at the same position, but always goes past half way. I was expecting a stack overflow exception at least. Here's my code: public class Engine { public int[,] Create() { int[,] outer = new int[9, 9]; for (int i = 0; i < 9; i++) { for (int j = 0; j < 9; j++) { outer[i, j] = GetRandom(GetUsed(outer, i, j)); } } return outer; } List<int> GetUsed(int[,] arr, int x, int y) { List<int> usedNums = new List<int>(); for (int i = 0; i < 9; i++) { if (arr[x, i] != 0 && i != y) { if(!usedNums.Contains(arr[x, i])) usedNums.Add(arr[x, i]); } } for (int i = 0; i < 9; i++) { if (arr[i, y] != 0 && i != x) { if (!usedNums.Contains(arr[i, y])) usedNums.Add(arr[i, y]); } } int x2 = 9 - (x + 1); int y2 = 9 - (y + 1); if (x2 <= 3) x2 = 2; else if (x2 > 3 && x2 <= 6) x2 = 5; else x2 = 8; if (y2 <= 3) y2 = 2; else if (y2 > 3 && y2 <= 6) y2 = 5; else y2 = 8; for (int i = x2 - 2; i < x2; i++) { for (int j = y2 - 2; j < y2; j++) { if (arr[i, j] != 0 && i != x && j != y) { if (!usedNums.Contains(arr[i, j])) usedNums.Add(arr[i, j]); } } } return usedNums; } int GetRandom(List<int> numbers) { Random r; int newNum; do { r = new Random(); newNum = r.Next(1, 10); } while (numbers.Contains(newNum)); return newNum; } }

  • What free OS should I use on my VPS?

    - by earlz
    Hello, I looked a bit but didn't see any duplicate of this so my question is which free(open source) OS do you use on servers and why do you use that OS? Background I have a VPS at Linode. There is a broad range of options for which OS I can put on it including both 32 and 64bit OSs. I just use it to run my small blog and for hosting random files. It's very low traffic. I have been using 64bit Arch Linux on my VPS and though I love the OS for general usage, for a server the constant breakage is troublesome. So I'm considering trying something new and am looking for suggestions.

  • Sharing Windows Folders on a Network... other PCs see but can't access

    - by John
    I'm soooo tired of network setup issues. All I want to do is share a folder and all it's sub-folders so other PCs on my network can view and change this remote location. Why is it that setting a dir to "shared" doesn't actually make it usable in any way? The other PC can see the fodler but is unable to actually open it and look inside. It seems every time I want to do this I go through some semi-random process of right clicking the folder and enabling sharing, then looking in the folder properties to add permissions and other sharing... and then I end up with some folders working but others will randomly block permission on certain files or sub-dirs. I have 5 PCs in my local testing network and I cannot believe it should be this complicated... where is the simple "make this folder work on the network" option?! I have a mixture of XP, Vista & W7 machines, but this seems common to all of them.

  • Spring Integration 1.0 RC2: Streaming file content?

    - by gdm
    I've been trying to find information on this, but due to the immaturity of the Spring Integration framework I haven't had much luck. Here is my desired work flow: New files are placed in an 'Incoming' directory Files are picked up using a file:inbound-channel-adapter The file content is streamed, N lines at a time, to a 'Stage 1' channel, which parses the line into an intermediary (shared) representation. This parsed line is routed to multiple 'Stage 2' channels. Each 'Stage 2' channel does its own processing on the N available lines to convert them to a final representation. This channel must have a queue which ensures no Stage 2 channel is overwhelmed in the event that one channel processes significantly slower than the others. The final representation of the N lines is written to a file. There will be as many output files as there were routing destinations in step 4. *'N' above stands for any reasonable number of lines to read at a time, from [1, whatever I can fit into memory reasonably], but is guaranteed to always be less than the number of lines in the full file. How can I accomplish streaming (steps 3, 4, 5) in Spring Integration? It's fairly easy to do without streaming the files, but my files are large enough that I cannot read the entire file into memory. As a side note, I have a working implementation of this work flow without Spring Integration, but since we're using Spring Integration in other places in our project, I'd like to try it here to see how it performs and how the resulting code compares for length and clarity.

  • Can't see *all* databases in a remote SQL Server instance

    - by George
    Yesterday I posted a related question on StackOverflow. This problem involved not being able to see a SQL Server 2008 instance on another PC. I am not sure why adding the port number enabled me to see a SQL Server that I could not otherwise see, since the port number that I specified was, after all, the default port. Now I notice that I have another problem. While I can connect to the remote SQL 2008 Server instance, I cannot see all the databases in the instance. I am trying to connect to the 2008 instance from another PC using SQL Server 2008 Mgt Studio. I am connecting from a Windows 7 Ultimate PC to a Windows XP Pro PC. I suspect that my problem has something to do with not all database in the remote instance having the same version. For example, I "upgraded" a a SL 2005 database to 2008 by doing a backup frm 2005 and importing it into 2008. When I realized that this was not one of the database that I could see from my other PC, I noticed that the compatability level of the imported was still 2005, so I changed it to 2008. Still I could not see the database. I am sure that this is relevant: I just noticed that on my remote server, the sql node instance node, named "sql2008" says "version 10" when I am on the remote serfver, but when I connect to the sql2008 remote instance fron my local PC, the connection is shown locally as being a "SQL Servr version 8.0" instance. I suspect that locally, I am only being shown databases that are somehow in the remote 2008 instance but have not been upgraded. I guess I don't know what constitutes an upgraded database and I don not know who to connect to see all the databases, even if this requires multiple connections from the source PC.

  • How to report progress of a JavaScript function?

    - by LambyPie
    I have a JavaScript function which is quite long and performs a number of tasks, I would like to report progress to the user by updating the contents of a SPAN element with a message as I go. I tried adding document.getElementById('spnProgress').innerText = ... statements throughout the function code. However, whilst the function is executing the UI will not update and so you only ever see the last message written to the SPAN which is not very helpful. My current solution is to break the task up into a number of functions, at the end of each I set the SPAN message and then "trigger" the next one with a window.setTimeout call with a very short delay (say 10ms). This yields control and allows the browser to repaint the SPAN with the updated message before starting the next step. However I find this very messy and difficult to follow the code, I'm thinking there must be a better way. Does anyone have any suggestions? Is there any way to force the SPAN to repaint without having to leave the context of the function? Thanks

  • Producer consumer with qualifications

    - by tgguy
    I am new to clojure and am trying to understand how to properly use its concurrency features, so any critique/suggestions is appreciated. So I am trying to write a small test program in clojure that works as follows: there 5 producers and 2 consumers a producer waits for a random time and then pushes a number onto a shared queue. a consumer should pull a number off the queue as soon as the queue is nonempty and then sleep for a short time to simulate doing work the consumers should block when the queue is empty producers should block when the queue has more than 4 items in it to prevent it from growing huge Here is my plan for each step above: the producers and consumers will be agents that don't really care for their state (just nil values or something); i just use the agents to send-off a "consumer" or "producer" function to do at some time. Then the shared queue will be (def queue (ref [])). Perhaps this should be an atom though? in the "producer" agent function, simply (Thread/sleep (rand-int 1000)) and then (dosync (alter queue conj (rand-int 100))) to push onto the queue. I am thinking to make the consumer agents watch the queue for changes with add-watcher. Not sure about this though..it will wake up the consumers on any change, even if the change came from a consumer pulling something off (possibly making it empty) . Perhaps checking for this in the watcher function is sufficient. Another problem I see is that if all consumers are busy, then what happens when a producer adds something new to the queue? Does the watched event get queued up on some consumer agent or does it disappear? see above I really don't know how to do this. I heard that clojure's seque may be useful, but I couldn't find enough doc on how to use it and my initial testing didn't seem to work (sorry don't have the code on me anymore)

  • Doctrine - get the offset of an object in a collection (implementing an infinite scroll)

    - by dan
    I am using Doctrine and trying to implement an infinite scroll on a collection of notes displayed on the user's browser. The application is very dynamic, therefore when the user submits a new note, the note is added to the top of the collection straightaway, besides being sent (and stored) to the server. Which is why I can't use a traditional pagination method, where you just send the page number to the server and the server will figure out the offset and the number of results from that. To give you an example of what I mean, imagine there are 20 notes displayed, then the user adds 2 more notes, therefore there are 22 notes displayed. If I simply requests "page 2", the first 2 items of that page will be the last two items of the page currently displayed to the user. Which is why I am after a more sophisticated method, which is the one I am about to explain. Please consider the following code, which is part of the server code serving an AJAX request for more notes: // $lastNoteDisplayedId is coming from the AJAX request $lastNoteDisplayed = $repository->findBy($lastNoteDisplayedId); $allNotes = $repository->findBy($filter, array('createdAt' => 'desc')); $offset = getLastNoteDisplayedOffset($allNotes, $lastNoteDisplayedId); // retrieve the page to send back so that it can be appended to the listing $notesPerPage = 30 $notes = $repository->findBy( array(), array('createdAt' => 'desc'), $notesPerPage, $offset ); $response = json_encode($notes); return $response; Basically I would need to write the method getLastNoteDisplayedOffset, that given the whole set of notes and one particoular note, it can give me its offset, so that I can use it for the pagination of the previous Doctrine statement. I know probably a possible implementation would be: getLastNoteDisplayedOffset($allNotes, $lastNoteDisplayedId) { $i = 0; foreach ($allNotes as $note) { if ($note->getId() === $lastNoteDisplayedId->getId()) { break; } $i++; } return $i; } I would prefer not to loop through all notes because performance is an important factor. I was wondering if Doctrine has got a method itself or if you can suggest a different approach.

  • Server suddenly running out of entropy

    - by Creshal
    Since a reboot yesterday, one of our virtual servers (Debian Lenny, virtualized with Xen) is constantly running out of entropy, leading to timeouts etc. when trying to connect over SSH / TLS-enabled protocols. Is there any way to check which process(es) is(/are) eating up all the entropy? Edit: What I tried: Adding additional entropy sources: time_entropyd, rng-tools feeding urandom back into random, pseudorandom file accesses – netted about 1 MiB additional entropy per second, problems still persisted Checking for unusual activity via lsof, netstat and tcpdump – nothing. No noticeable load or anything Stopping daemons, restarting permanent sessions, rebooting the entire VM – no change in behaviour What in the end worked: Waiting. Since about yesterday noon, there are no connection problems anymore. Entropy is still somewhat low (128 Bytes peak), but TLS/SSH sessions have no noticeable delay anymore. I'm slowly switching our clients back to TLS (all five of them!), but I don't expect any change in behavior now.

  • Django - foreignkey problem

    - by realshadow
    Hey, Imagine you have this model: class Category(models.Model): node_id = models.IntegerField(primary_key = True) type_id = models.IntegerField(max_length = 20) parent_id = models.IntegerField(max_length = 20) sort_order = models.IntegerField(max_length = 20) name = models.CharField(max_length = 45) lft = models.IntegerField(max_length = 20) rgt = models.IntegerField(max_length = 20) depth = models.IntegerField(max_length = 20) added_on = models.DateTimeField(auto_now = True) updated_on = models.DateTimeField(auto_now = True) status = models.IntegerField(max_length = 20) node = models.ForeignKey(Category_info, verbose_name = 'Category_info', to_field = 'node_id' The important part is the foreignkey. When I try: Category.objects.filter(type_id = type_g.type_id, parent_id = offset, status = 1) I get an error that get returned more than category, which is fine, because it is supposed to return more than one. But I want to filter the results trough another field, which would be type id (from the second Model) Here it is: class Category_info(models.Model): objtree_label_id = models.AutoField(primary_key = True) node_id = models.IntegerField(unique = True) language_id = models.IntegerField() label = models.CharField(max_length = 255) type_id = models.IntegerField() The type_id can be any number from 1 - 5. I am desparately trying to get only one result where the type_id would be number 1. Here is what I want in sql: SELECT n.*, l.* FROM objtree_nodes n JOIN objtree_labels l ON (n.node_id = l.node_id) WHERE n.type_id = 15 AND n.parent_id = 50 AND l.type_id = 1 Any help is GREATLY appreciated.

  • jQuery accordion link issue

    - by Josh
    Slight problem, I've been working with a multi-accordion for a News panel. Everything is working fine, but there is an issue that has just recently come up. Underneath the headline I have information on when said headline+article was posted and when, and also if there are any comments. I intended to make the author and the number of comments as a link. The author link would most likely bring them to their contact page or maybe an email, the number of comments link would just expand it directly to the "View comments" which the user could also access by just expanding the article and then expanding the comments. A shortcut basically. Now, the issue is that I'm having to put this "Posted by..." information inside the a class which allows the user to expand the headline into the article. If I do this however, it breaks the entire accordion field for that headline because there are multiple A HREF links inside the original A link. I really don't know how to get around this, if anyone has a tip or a solution I would most appreciate it, thanks. You can view the demo here: http://www.notedls.com/demo

  • [Database] How to model this one-to-one relation?

    - by pbean
    I have several entities which respresent different types of users who need to be able to log in to a particular system. Additionally, they have different types of information associated with them. For example: a "general user", which has an e-mail address and "admin user", which has a workstation number (note that this a hypothetical case). Both entities also share common properties like first name, surname, address and telephone number. Finally, they naturally need to have a (unique) user name and a password to log in. In the application, the user just has to fill in his user name and password, and the functionality of the application changes slightly according to the type of the user. You can imagine that the username needs to be unique for this work. How should I model this effectively? I can't just create two tables, because then I can't force a unique constaint on the user name. I also can't put them all in just one table, because they have different types of specific information associated to them. I think I might need 3 seperate tables, one for "users" (with user name and password), one for the "general users" and another one for the "admin users", but how would the relations between these work? Or is there another solution? (By the way, the target DBMS is MySQL, so I don't think generalization is supported in the database system itself).

  • lighttpd silently stops logging

    - by Max Cantor
    I'm on a Slicehost 256MB VPS with Ubuntu 9.04 (Jaunty). lighttpd is the only web server process running; it listens on port 80. My lighttpd.conf can be found here. I'm using Ubuntu's default logrotate setup for lighty. At seemingly random times, lighttpd will stop logging. It is not correlated with log rotation--that is, the errors do not occur when logrotate kicks in. What happens is, I will verify that the server is serving files by hitting a URL with my browser, and I will verify that it is not logging by checking access.log and seeing that the GET request I just made is not there. Using init.d to restart the process starts logging again, without truncating or rotating the log file. That is, new requests will be logged at the end of the existing access.log file. There are no cron jobs running on this box. Any ideas?

  • How do I display java.lang.* object allocations in Eclipse profiler?

    - by Martin Wickman
    I am profiling an application using the Eclipse profiler. I am particularly interested in number of allocated object instances of classes from java.lang (for instance java.lang.String or java.util.HashMap). I also want to know stuff like number of calls to String.equals() etc. I use the "Object Allocations" tab and I shows all classes in my application and a count. It also shows all int[], byte[], long[] etc, but there is no mention of any standard java classes. For instance, this silly code: public static void main(String[] args) { Object obj[] = new Object[1000]; for (int i = 0; i < 1000; i++) { obj[i] = new StringBuffer("foo" + i); } System.out.println (obj[30]); } Shows up in the Object Allocations tab as 7 byte[]s, 4 char[]s and 2 int[]s. It doesn't matter if I use 1000 or 1 iterations. It seems the profiler simply ignores everything that is in any of the java.* packages. The same applies to Execution Statistics as well. Any idea how to display instances of java.* in the Eclipse Profiler?

  • What's the behaviour when opening a group of files at once?

    - by Leo King
    I selected a group of .odt files, right-clicked the first one and selected open. I would have thought they would open in alphabetical order, but as the second screenshot shows, they're not - the one with "2014-11-13" opens before "2013-10-23". And then when I select the whole group and press Enter, they open in order - and sometimes they don't. What's the behaviour when you right-click and open for a batch of files? Does it start with the one you selected and pick random files in the list to open next?

    I'm trying to iterate through all the combinations of pairs of positive long integers in Java and testing the sum of their cubes to discover if it's a Fibonacci number. I'm currently doing this by using the value of the outer loop variable as the inner loop's upper limit, with the effect being that the outer loop runs a little slower each time. Initially it appeared to run very quickly--I was up to 10 digits within minutes. But now after 2 full days of continuous execution, I'm only somewhere in the middle range of 15 digits. At this rate it may end up taking a whole year just to finish running this program. The code for the program is below: import java.lang.*; import java.math.*; public class FindFib { public static void main(String args[]) { long uLimit=9223372036854775807L; //long maximum value BigDecimal PHI=new BigDecimal(1D+Math.sqrt(5D)/2D); //Golden Ratio for(long a=1;a<=uLimit;a++) //Outer Loop, 1 to maximum for(long b=1;b<=a;b++) //Inner Loop, 1 to current outer { //Cube the numbers and add BigDecimal c=BigDecimal.valueOf(a).pow(3).add(BigDecimal.valueOf(b).pow(3)); System.out.print(c+" "); //Output result //Upper and lower limits of interval for Mobius test: [c*PHI-1/c,c*PHI+1/c] BigDecimal d=c.multiply(PHI).subtract(BigDecimal.ONE.divide(c,BigDecimal.ROUND_HALF_UP)), e=c.multiply(PHI).add(BigDecimal.ONE.divide(c,BigDecimal.ROUND_HALF_UP)); //Mobius test: if integer in interval (floor values unequal) Fibonacci number! if (d.toBigInteger().compareTo(e.toBigInteger())!=0) System.out.println(); //Line feed else System.out.print("\r"); //Carriage return instead } //Display final message System.out.println("\rDone. "); } } Now the use of BigDecimal and BigInteger was delibrate; I need them to get the necessary precision. Is there anything other than my variable types that I could change to gain better efficiency?
