  • jquery: mouseleave event seems to fire when it's not supposed to

    - by Jeremy
    Given the following html table and script shown below I am having a problem where the mouse leave event appears to fire right after the mouse enter, even if I don't move the mouse out of the row. <script type="text/javascript" language="javascript"> function highlightRows(iMainID) { $('tr[mainid=' + iMainID+ ']').each(function() { if ($(this).attr('old') == undefined) { $(this).attr('old', $(this).css('backgroundColor')); } $(this).animate({ backgroundColor: "#FFFFCC" }, 500); $(this).mouseout(function() { if ($(this).attr('old') != undefined) { $(this).animate({ backgroundColor: $(this).attr('old') }, 500); } }); }); } </script> <table> <tr> <td mainid="1" onmouseover='highlightRows(1)'><div>text</div></td> <td mainid="1" onmouseover='highlightRows(1)'><div>text</div></td> <td mainid="2" onmouseover='highlightRows(2)'><div>text</div></td> </tr> <table>

  • Java assignment issues - Is this atomic?

    - by Bob
    Hi, I've got some questions about Java's assigment. Strings I've got a class: public class Test { private String s; public synchronized void setS(String str){ s = s + " - " + str; } public String getS(){ return s; } } I'm using "synchronized" in my setter, and avoiding it in my getter, because in my app, there are a tons of data gettings, and very few settings. Settings must be synchronized to avoid inconsistency. My question is: is getting and setting a variable atomic? I mean, in a multithreaded environment, Thread1 is about to set variable s, while Thread2 is about to get "s". Is there any way the getter method could get something different than the s's old value or the s's new value (suppose we've got only two threads)? In my app it is not a problem to get the new value, and it is not a problem to get the old one. But could I get something else? What about HashMap's getting and putting? considering this: public class Test { private Map<Integer, String> map = Collections.synchronizedMap(new HashMap<Integer, String>()); public synchronized void setMapElement(Integer key, String value){ map.put(key, value); } public String getValue(Integer key){ return map.get(key); } } Is putting and getting atomic? How does HashMap handle putting an element into it? Does it first remove the old value and put the now one? Could I get other than the old value or the new value? Thanks in advance!

  • JS: capture a static snapshot of an object at a point in time with a method

    - by Barney
    I have a JS object I use to store DOM info for easy reference in an elaborate GUI. It starts like this: var dom = { m:{ old:{}, page:{x:0,y:0}, view:{x:0,y:0}, update:function(){ this.old = this; this.page.x = $(window).width(); this.page.y = $(window).height(); this.view.x = $(document).width(); this.view.y = window.innerHeight || $(window).height(); } I call the function on window resize: $(window).resize(function(){dom.m.update()}); The problem is with dom.m.old. I would have thought that by calling it in the dom.m.update() method before the new values for the other properties are assigned, at any point in time dom.m.old would contain a snapshot of the dom.m object as of the last update – but instead, it's always identical to dom.m. I've just got a pointless recursion method. Why isn't this working? How can I get a static snapshot of the object that won't update without being specifically told to? Comments explaining how I shouldn't even want to be doing anything remotely like this in the first place are very welcome :)

  • question about MySQL database migration

    - by WilliamLou
    Hi there: If I have a MySQL database with several tables on a live server, now I would like to migrate this database to another server. Of course, the migration I mean here involves some database tables, for example: add some new columns to several tables, add some new tables etc.. Now, the only method I can think of is to use some php/python(two scripts I know) script, connect two databases, dump the data from the old database, and then write into the new database. However, this method is not efficient at all. For example: in old database, table A has 28 columns; in new database, table A has 29 columns, but the extra column will have default value 0 for all the old rows. My script still needs to dump the data row by row and insert each row into the new database. Is there any tools or a better method than writing a script yourself? Here, I dont need to worry about multithread writing problems etc.., I mean the old database will be down (not open to public usage etc.., only for upgrade ) for a while. Thanks!!

  • mysql subselect alternative

    - by Arnold
    Hi, Lets say I am analyzing how high school sports records affect school attendance. So I have a table in which each row corresponds to a high school basketball game. Each game has an away team id and a home team id (FK to another "team table") and a home score and an away score and a date. I am writing a query that matches attendance with this seasons basketball games. My sample output will be (#_students_missed_class, day_of_game, home_team, away_team, home_team_wins_this_season, away_team_wins_this_season) I now want to add how each team did the previous season to my analysis. Well, I have their previous season stored in the game table but i should be able to accomplish that with a subselect. So in my main select statement I add the subselect: SELECT COUNT(*) FROM game_table WHERE game_table.date BETWEEN 'start of previous season' AND 'end of previous season' AND ( (game_table.home_team = team_table.id AND game_table.home_score > game_table.away_score) OR (game_table.away_team = team_table.id AND game_table.away_score > game_table.home_score)) In this case team-table.id refers to the id of the home_team so I now have all their wins calculated from the previous year. This method of calculation is neither time nor resource intensive. The Explain SQL shows that I have ALL in the Type field and I am not using a Key and the query times out. I'm not sure how I can accomplish a more efficient query with a subselect. It seems proposterously inefficient to have to write 4 of these queries (for home wins, home losses, away wins, away losses). I am sure this could be more lucid. I'll absolutely add color tomorrow if anyone has questions

  • Emailing an excel sheet with SSL in Python

    - by jakecar
    Hi...this is my first post so let me know if there are any common courtesies I should know about. I just started programming 8 months ago, so I am fairly new. I have been doing some projects to get better. A project I'm working on now creates an Excel sheet from inputted data. It's in Python, which I just started learning a couple of weeks ago. I'm attempting to embed part of this Excel sheet into an email, sent from my school address. I have spent hours looking this up, and to no avail. There are two problems I am asking for help with: 1) I have figured out how to send an email from my GMail account, but not from my school address. My school email uses SSL port 465, which I have tried to use, but to no avail. Unfortunately, I have been having a problem setting up outgoing email for this account on my iPhone as well. It may be related? Does anyone know of common issues relating to outgoing email with SSL and Python? 2) Excel has an option of saving a sheet as a HTML. When doing so, I copy and pasted the HTML source and emailed it as an attachment. Unfortunately, the colored text did not transfer over. Does anyone know of a better way of using Python to send an excel sheet embedded in an email? Thanks for your help!

  • Matching several items inside one string with preg_match_all() and end characters

    - by nefo_x
    I have the following code: preg_match_all('/(.*) \((\d+)\) - ([\d\.\d]+)[,?]/U', "E-Book What I Didn't Learn At School... (2) - 3525.01, FREE Intro DVD/Vid (1) - 0.15", $match); var_dump($string, $match); and get the following ouput: array(4) { [0]=> array(1) { [0]=> string(54) "E-Book What I Didn't Learn At School... (2) - 3525.01," } [1]=> array(1) { [0]=> string(39) "E-Book What I Didn't Learn At School..." } [2]=> array(1) { [0]=> string(1) "2" } [3]=> array(1) { [0]=> string(7) "3525.01" } } which matches only one items... what i need is to get all items from such strings. when i've added "," sign to the end of the string - it worked fine. but that is non-sense in adding comma to each string. Any advice?

  • Hashtable resizing leaks memory

    - by thpetrus
    I wrote a hashtable and it basically consists of these two structures: typedef struct dictEntry { void *key; void *value; struct dictEntry *next; } dictEntry; typedef struct dict { dictEntry **table; unsigned long size; unsigned long items; } dict; dict.table is a multidimensional array, which contains all the stored key/value pair, which again are a linked list. If half of the hashtable is full, I expand it by doubling the size and rehashing it: dict *_dictRehash(dict *d) { int i; dict *_d; dictEntry *dit; _d = dictCreate(d->size * 2); for (i = 0; i < d->size; i++) { for (dit = d->table[i]; dit != NULL; dit = dit->next) { _dictAddRaw(_d, dit); } } /* FIXME memory leak because the old dict can never be freed */ free(d); // seg fault return _d; } The function above uses the pointers from the old hash table and stores it in the newly created one. When freeing the old dict d a Segmentation Fault occurs. How am I able to free the old hashtable struct without having to allocate the memory for the key/value pairs again?

  • Learning Basic Mathematics

    - by NeedsToKnow
    I'm going to just come out and say it. I'm 20 and can't do maths. Two years ago I passed the end-of-high-school mathematics exam (but not at school), and did pretty well. Since then, I haven't done a scrap of mathematics. I wondered just how bad I had gotten, so I was looking at some simple algebra problems. You know, the kind you learn halfway through highschool. 5(-3x - 2) - (x - 3) = -4(4x + 5) + 13 Couldn't do them. I've got half a year left until I start a Computer Science undergraduate degree. I love designing and creating programs, and I remember I loved mathematics back when I did it. Basically, I've had a pretty bad education, but I want to be knowledgable in these areas. I was thinking of buying some high school textbooks and reading them, but I'm not sure this is the right way to go. I need to start off at some basic level and work towards a greater understanding. My question is: What should I study, how should I study, and what books can you recommend? Thanks!

  • Have you had DLL's fail after upgrading to 64 bit server?

    - by quakkels
    Hey All, I'm wondering if anyone else has experienced failed DLL's after upgrading their servers. My company is in the process of upgrading our code and server's after ten years of using classic ASP. We've set up our new server running Windows 2008 and IIS 7. Our classic ASP code and our new asp.net mvc code work pretty well. Our problems started happening when we began moving our old websites to the new server. When trying to load the page on the actual server machine's browser, we initially got a 500 error. If we refreshed the page then some of the page would load but then display an error: Server object error 'ASP 0177 : 800401f3' Server.CreateObject Failed /folder/scriptname.asp, line 24 800401f3 btw: On remote machines we would just get 500 errors. Line 24 is the first executable code in the script: '23 lines of comments set A0SQL_DATA = server.createobject("olddllname.Data") 'the rest of the script That specific line is trying to use a ten year old DLL to create a server object. I don't think the server configuration is a problem because I'm able to create "adodb.recordset" server objects without any problems. Is there an issue when running correctly registered old DLL's on 64 bit systems? Is there a way to get old DLL's working on 64 bit systems?

  • Hi, how can I use the check box group in JSF to select the items of database and generate a list in

    - by Alexzzy
    I am using netbean and JSF to do my project, recently I encountered a problem that confused me. The question: There is a set of check box groups that identify the artifacts from the nature, creator, period and school. And all the artifacts are stored in a table of database. I would like to select the items by nature or creator or something like that, and generate a list for the items selected in the next page. There are some tables of database for artifacts, nature, creators and school, and the type_ID(this is the nature), creator_ID, school_ID are the foreign keys in artifacts table. I have bound the tables with respective check boxes. For example, if I want to select nature is painting, creator is Davinci, school is Italian Renaissance, and then I click Search button. It will go to next page that generate a list of artifacts about all Italian Renaissance paintings created by Davinci. How can I do that? I was confused by JSF, but I have to use JSF to do my project. Anyone can help me plz??? Thank you very very much !!!!!!!

  • changing the serialization procedure for a graph of objects (.net framework)

    - by pierusch
    Hello I'm developing a scientific application using .net framework. The application depends heavily upon a large data structure (a tree like structure) that has been serialized using a standard binaryformatter object. The graph structure looks like this: <serializable()>Public class BigObjet inherits list(of smallObject) end class <serializable()>public class smallObject inherits list(of otherSmallerObjects) end class ... The binaryFormatter object does a nice job but it's not optimized at all and the entire data structure reaches around 100Mb on my filesystem. Deserialization works too but it's pretty slow (around 30seconds on my quad core). I've found a nice .dll on codeproject (see "optimizing serialization...") so I wrote a modified version of the classes above overriding the default serialization/deserialization procedure reaching very good results. The problem is this: I can't lose the data previosly serialized with the old version and I'd like to be able to use the new serialization/deserialization method. I have some ideas but I'm pretty sure someone will be able to give me a proper and better advice ! use an "helper" graph of objects who takes care of the entire serialization/deserialization procedure reading data from the old format and converting them into the classes I nedd. This could work but the binaryformatter "needs" to know the types being serialized so........ :( modify the "old" graph to include a modified version of serialization procedure...so I'll be able to deserialize old file and save them with the new format......this doesn't sound too good imho. well any help will be higly highly appreciated :)

  • Excessive use of Inner Join for more than 3 tables

    - by Archangel08
    Good Day, I have 4 tables on my DB (not the actual name but almost similar) which are the ff: employee,education,employment_history,referrence employee_id is the name of the foreign key from employee table. Here's the example (not actual) data: **Employee** ID Name Birthday Gender Email 1 John Smith 08-15-2014 Male [email protected] 2 Jane Doe 00-00-0000 Female [email protected] 3 John Doe 00-00-0000 Male [email protected] **Education** Employee_ID Primary Secondary Vocation 1 Westside School Westshore H.S SouthernBay College 2 Eastside School Eastshore H.S NorthernBay College 3 Northern School SouthernShore H.S WesternBay College **Employment_History** Employee_ID WorkOne StartDate Enddate 1 StarBean Cafe 12-31-2012 01-01-2013 2 Coffebucks Cafe 11-01-2012 11-02-2012 3 Latte Cafe 01-02-2013 04-05-2013 Referrence Employee_ID ReferrenceOne Address Contact 1 Abraham Lincoln Lincoln Memorial 0000000000 2 Frankie N. Stein Thunder St. 0000000000 3 Peter D. Pan Neverland Ave. 0000000000 NOTE: I've only included few columns though the rest are part of the query. And below are the codes I've been working on for 3 consecutive days: $sql=mysql_query("SELECT emp.id,emp.name,emp.birthday,emp.pob,emp.gender,emp.civil,emp.email,emp.contact,emp.address,emp.paddress,emp.citizenship,educ.employee_id,educ.elementary,educ.egrad,educ.highschool,educ.hgrad,educ.vocational,educ.vgrad,ems.employee_id,ems.workOne,ems.estartDate,ems.eendDate,ems.workTwo,ems.wstartDate,ems.wendDate,ems.workThree,ems.hstartDate,ems.hendDate FROM employee AS emp INNER JOIN education AS educ ON educ.employee_id='emp.id' INNER JOIN employment_history AS ems ON ems.employee_id='emp.id' INNER JOIN referrence AS ref ON ref.employee_id='emp.id' WHERE emp.id='$id'"); Is it okay to use INNER JOIN this way? Or should I modify my query to get the results that I wanted? I've also tried to use LEFT JOIN but still it doesn't return anything .I didn't know where did I go wrong. You see, as I have thought, I've been using the INNER JOIN in correct manner, (since it was placed before the WHILE CLAUSE). So I couldn't think of what could've possible went wrong. Do you guys have a suggestion? Thanks in advance.

  • Tool to migrate a repo with only read access?

    - by Corazu
    I have a subversion repository located on our school servers from a project my friends and I worked on the past semester. We want to take the project and polish it and make it more of a portfolio item and I'm not quite sure that the repo will stay intact on the school servers (they usually wipe it after a few semesters). I don't have access to dump the repo, although I've sent an email to see if I can get one - which would be the best solution. I tried svnsync but the school server doesn't support the replay command (probably turned off), so that won't work for me. Now, theoretically, wouldn't it be possible to (manually or programmatically) checkout each revision of the repository and check it in to a new repository on our own server? I think it would work - there's only 3 of us, and there's no working copy conflicts that we'd have to worry about, just want a copy of all the history in the repo in case we need to go back and look at it. That being said, before I go and reinvent a wheel by writing a script to do it - does something like this already exist? I have to figure there's already a tool to do it, or that someone has wrote a script to do it.

  • Display two array's in the same table

    - by Naeem Ahmed
    $row = $query->fetchAll(PDO::FETCH_ASSOC); $num_rows = count($row); for ($i = 0; $i < $num_rows; $i++) { $title = htmlspecialchars($row[$i]['title']); $author =htmlspecialchars($row[$i]['author']); $school =htmlspecialchars($row[$i]['school']); $solution = $row[$i]['solution']; $notes = $row[$i]['notes']; $ad = array($title, $price, $author, $school, $contact, $content, $date); $inlcude = array($solutions, $notes); $field = 0; echo "<table border='1'>"; // foreach($inlcude as $in) This failled miserably foreach ($ad as $post) { if ($field < 3) //The first three values are placed in the first row { echo "<td>$post</td>"; } if ($field >= 3) { echo "<tr><td>$post</td><td>$in</td></tr>"; } $field++; } echo '</table>'; } I have two arrays and I would like to display them in different columns in my table. $ad displays perfectly fine but I'm having trouble displaying the contents in $inlcude in the second column. I've tried putting another foreach loop to iterate through contents of the second array but that really screws up my table by placing random values in different places on the table. Besides the foreach loop, I don't know of any other way to iterate through the array. Any suggestions would be appreciated.Thanks!

  • Why does this php/ajax query fail?

    - by Ashley Brown
    I'm ajaxing over to this php file. $a = 'old'; $b = 'new'; if ($_POST['info-type'] == $a || $b) { $info = $_POST['info-type']; $query = "SELECT * FROM `tld` WHERE type = '".$var."'"; } $query = "SELECT * FROM `tld` "; $result = mysqli_query($link,$query); while($row = mysqli_fetch_assoc($result)) { echo '<div>'.$row['something'].'</div>'; } The data posted is either 'all' 'new' or 'old'. If i send the data as either new or old, the script works and outputs as expected. If the posted data is neither new or old but all instead, it fails and don't show any errors or respond anything back. (I've monitored via dev tools aswell) So, I tried this if ($_POST['info-type'] == $a || $b) { $info = $_POST['info-type']; $var = "SELECT * FROM `tld` WHERE type = '".$var."'"; } elseif ($_POST['info-type'] == 'all'){ $query = "SELECT * FROM `tld` "; } But the script still fails. If i fully remove the IF statements and use the query without the WHERE clause like it is after the elseif, it works?

  • Shouldn't we ignore IE6 and IE7 users?

    - by Sebi
    Lately I created two webpages with a simple CMS for a a small club and a private person (http://foto.roser.li and http://www.ovlu.li/cms). I dont really understand much of HTML/PHP/CSS and all this web stuff, but it was enough to adapt the stylesheets and add some javascript functions and so on to make the pages to look more or less nice in firefox and IE8. Nevertheles, if you open the pages with IE7 or IE6, particulary the second home page really looks terrible. So what should I do know? I don't have the know-how to adapt the stylesheets so that it looks good at such browsers. However if I check the statistics of the pages, i noticed that almost half of the visitors uses this kind of browsers. I could put much effort in adapting the stylesheets to look good at all browser but while thinking about this I'm asking myself if this is really the best way. If all developers put effort in providing solutions for really old browsers (like e.g. the IE6), then people who use these brwoser dont have any incentives to update their browsers. Naturally, I as a provider of information should present the content in a readable form to my users, but were should i draw the line? I also saw that some users are visiting the pages with even IE5 or IE4... but I really can't think of a way how to adapt the content in a suitable form for these very old brwosers. I would appreciaed any hints how to handle this balancing between putting much effort into developing a version for very old brwosers and the necessity of providing content to all users which want to visits my homepages. Im also interested in your thoughts about they idea that putting effort in adapting the content for old browsers prevents the users from updating their browsres because they don't see any need.

  • iptables syn flood countermeasure

    I'm trying to adjust my iptables firewall to increase the security of my server, and I found something a bit problematic here : I have to set INPUT policy to ACCEPT and, in addition, to have a rule saying iptables -I INPUT -i eth0 -j ACCEPT. Here comes my script (launched manually for tests) : #!/bin/sh IPT=/sbin/iptables echo "Clearing firewall rules" $IPT -F $IPT -Z $IPT -t nat -F $IPT -t nat -Z $IPT -t mangle -F $IPT -t mangle -Z $IPT -X echo "Defining logging policy for dropped packets" $IPT -N LOGDROP $IPT -A LOGDROP -j LOG -m limit --limit 5/min --log-level debug --log-prefix "iptables rejected: " $IPT -A LOGDROP -j DROP echo "Setting firewall policy" $IPT -P INPUT DROP # Deny all incoming connections $IPT -P OUTPUT ACCEPT # Allow all outgoing connections $IPT -P FORWARD DROP # Deny all forwaring echo "Allowing connections from/to lo and incoming connections from eth0" $IPT -I INPUT -i lo -j ACCEPT $IPT -I OUTPUT -o lo -j ACCEPT #$IPT -I INPUT -i eth0 -j ACCEPT echo "Setting SYN flood countermeasures" $IPT -A INPUT -p tcp -i eth0 --syn -m limit --limit 100/second --limit-burst 200 -j LOGDROP echo "Allowing outgoing traffic corresponding to already initiated connections" $IPT -A OUTPUT -p ALL -m state --state ESTABLISHED,RELATED -j ACCEPT echo "Allowing incoming SSH" $IPT -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --set --name SSH -j ACCEPT echo "Setting SSH bruteforce attacks countermeasures (deny more than 10 connections every 10 minutes)" $IPT -A INPUT -p tcp --dport 22 -m recent --update --seconds 600 --hitcount 10 --rttl --name SSH -j LOGDROP echo "Allowing incoming traffic for HTTP, SMTP, NTP, PgSQL and SolR" $IPT -A INPUT -p tcp --dport 25 -i eth0 -j ACCEPT $IPT -A INPUT -p tcp --dport 80 -i eth0 -j ACCEPT $IPT -A INPUT -p udp --dport 123 -i eth0 -j ACCEPT $IPT -A INPUT -p tcp --dport 5433 -i eth0.2654 -s 172.16.0.2 -j ACCEPT $IPT -A INPUT -p udp --dport 5433 -i eth0.2654 -s 172.16.0.2 -j ACCEPT $IPT -A INPUT -p tcp --dport 8983 -i eth0.2654 -s 172.16.0.2 -j ACCEPT $IPT -A INPUT -p udp --dport 8983 -i eth0.2654 -s 172.16.0.2 -j ACCEPT echo "Allowing outgoing traffic for ICMP, SSH, whois, SMTP, DNS, HTTP, PgSQL and SolR" $IPT -A OUTPUT -p tcp --dport 22 -j ACCEPT $IPT -A OUTPUT -p tcp --dport 25 -o eth0 -j ACCEPT $IPT -A OUTPUT -p tcp --dport 43 -o eth0 -j ACCEPT $IPT -A OUTPUT -p tcp --dport 53 -o eth0 -j ACCEPT $IPT -A OUTPUT -p udp --dport 53 -o eth0 -j ACCEPT $IPT -A OUTPUT -p tcp --dport 80 -o eth0 -j ACCEPT $IPT -A OUTPUT -p udp --dport 80 -o eth0 -j ACCEPT #$IPT -A OUTPUT -p tcp --dport 5433 -o eth0 -d 176.31.236.101 -j ACCEPT #$IPT -A OUTPUT -p udp --dport 5433 -o eth0 -d 176.31.236.101 -j ACCEPT #$IPT -A OUTPUT -p tcp --dport 8983 -o eth0 -d 176.31.236.101 -j ACCEPT #$IPT -A OUTPUT -p udp --dport 8983 -o eth0 -d 176.31.236.101 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 5433 -o eth0.2654 -j ACCEPT $IPT -A OUTPUT -p udp --sport 5433 -o eth0.2654 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 8983 -o eth0.2654 -j ACCEPT $IPT -A OUTPUT -p udp --sport 8983 -o eth0.2654 -j ACCEPT $IPT -A OUTPUT -p icmp -j ACCEPT echo "Allowing outgoing FTP backup" $IPT -A OUTPUT -p tcp --dport 20:21 -o eth0 -d 91.121.190.78 -j ACCEPT echo "Dropping and logging everything else" $IPT -A INPUT -s 0/0 -j LOGDROP $IPT -A OUTPUT -j LOGDROP $IPT -A FORWARD -j LOGDROP echo "Firewall loaded." echo "Maintaining new rules for 3 minutes for tests" sleep 180 $IPT -nvL echo "Clearing firewall rules" $IPT -F $IPT -Z $IPT -t nat -F $IPT -t nat -Z $IPT -t mangle -F $IPT -t mangle -Z $IPT -X $IPT -P INPUT ACCEPT $IPT -P OUTPUT ACCEPT $IPT -P FORWARD ACCEPT When I launch this script (I only have a SSH access), the shell displays every message up to Maintaining new rules for 3 minutes for tests, the server is unresponsive during the 3 minutes delay and then resume normal operations. The only solution I found until now was to set $IPT -P INPUT ACCEPT and $IPT -I INPUT -i eth0 -j ACCEPT, but this configuration does not protect me of any attack, which is a great shame for a firewall. I suspect that the error comes from my script and not from iptables, but I don't understand what's wrong with my script. Could some do-gooder explain me my error, please? EDIT: here comes the result of iptables -nvL with the "accept all input" ($IPT -P INPUT ACCEPT and $IPT -I INPUT -i eth0 -j ACCEPT) solution : Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 1 52 ACCEPT all -- eth0 * 0.0.0.0/0 0.0.0.0/0 0 0 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 0 0 LOGDROP tcp -- eth0 * 0.0.0.0/0 0.0.0.0/0 tcp flags:0x17/0x02 limit: avg 100/sec burst 200 0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 state NEW recent: SET name: SSH side: source 0 0 LOGDROP tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 recent: UPDATE seconds: 600 hit_count: 10 TTL-Match name: SSH side: source 0 0 ACCEPT tcp -- eth0 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:25 0 0 ACCEPT tcp -- eth0 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 0 0 ACCEPT udp -- eth0 * 0.0.0.0/0 0.0.0.0/0 udp dpt:123 0 0 ACCEPT tcp -- eth0.2654 * 172.16.0.2 0.0.0.0/0 tcp dpt:5433 0 0 ACCEPT udp -- eth0.2654 * 172.16.0.2 0.0.0.0/0 udp dpt:5433 0 0 ACCEPT tcp -- eth0.2654 * 172.16.0.2 0.0.0.0/0 tcp dpt:8983 0 0 ACCEPT udp -- eth0.2654 * 172.16.0.2 0.0.0.0/0 udp dpt:8983 0 0 LOGDROP all -- * * 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 LOGDROP all -- * * 0.0.0.0/0 0.0.0.0/0 Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT all -- * lo 0.0.0.0/0 0.0.0.0/0 2 728 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 0 0 ACCEPT tcp -- * eth0 0.0.0.0/0 0.0.0.0/0 tcp dpt:25 0 0 ACCEPT tcp -- * eth0 0.0.0.0/0 0.0.0.0/0 tcp dpt:43 0 0 ACCEPT tcp -- * eth0 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 0 0 ACCEPT udp -- * eth0 0.0.0.0/0 0.0.0.0/0 udp dpt:53 0 0 ACCEPT tcp -- * eth0 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 0 0 ACCEPT udp -- * eth0 0.0.0.0/0 0.0.0.0/0 udp dpt:80 0 0 ACCEPT tcp -- * eth0.2654 0.0.0.0/0 0.0.0.0/0 tcp spt:5433 0 0 ACCEPT udp -- * eth0.2654 0.0.0.0/0 0.0.0.0/0 udp spt:5433 0 0 ACCEPT tcp -- * eth0.2654 0.0.0.0/0 0.0.0.0/0 tcp spt:8983 0 0 ACCEPT udp -- * eth0.2654 0.0.0.0/0 0.0.0.0/0 udp spt:8983 0 0 ACCEPT icmp -- * * 0.0.0.0/0 0.0.0.0/0 0 0 ACCEPT tcp -- * eth0 0.0.0.0/0 91.121.190.78 tcp dpts:20:21 0 0 LOGDROP all -- * * 0.0.0.0/0 0.0.0.0/0 Chain LOGDROP (5 references) pkts bytes target prot opt in out source destination 0 0 LOG all -- * * 0.0.0.0/0 0.0.0.0/0 limit: avg 5/min burst 5 LOG flags 0 level 7 prefix `iptables rejected: ' 0 0 DROP all -- * * 0.0.0.0/0 0.0.0.0/0 EDIT #2 : I modified my script (policy ACCEPT, defining authorized incoming packets then logging and dropping everything else) to write iptables -nvL results to a file and to allow only 10 ICMP requests per second, logging and dropping everything else. The result proved unexpected : while the server was unavailable to SSH connections, even already established, I ping-flooded it from another server, and the ping rate was restricted to 10 requests per second. During this test, I also tried to open new SSH connections, which remained unanswered until the script flushed rules.

  • Need help with wp_rewrite in a WordPress Plugin

    - by Brad
    Ok, I've got this code that I've been using to spit out news to an application of mine. It was working until today. I've cutout all the logic in the following code to make it simpiler. But it should "WORK" Can someone help me fix this code to where it works, and is done right? I know it's hacked together ,but it didn't seem to have any problems until today. I have not updated anything, don't know what the deal is. Plugin Name: MyPlugin Example Version: 1.0.1 if ( ! class_exists("MyPlugin") ) { class MyPlugin { var $db_version = "1.0"; //not used yet function init() { //Nothing as of now. } function activate() { global $wp_rewrite; $this-flush_rewrite_rules(); } function pushoutput( $id ) { $output-out =' The output worked!'; $this-output( $output ); } function output( $output ) { ob_start(); ob_end_clean(); header( 'Cache-Control: no-cache, must-revalidate' ); header( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT' ); header( 'Content-type: application/json' ); echo json_encode( $output ); //Must encode this... } function flush_rewrite_rules() { global $wp_rewrite; $wp_rewrite-flush_rules(); } function createRewriteRules( $rewrite ) { global $wp_rewrite; $new_rules = array( 'MyPlugin/(.+)' = 'index.php?MyPlugin=' . $wp_rewrite-preg_index(1) ); if ( ! is_array($wp_rewrite-rules) ) { $wp_rewrite-rules = array(); } $wp_rewrite-rules = $new_rules + $wp_rewrite-rules; return $wp_rewrite; } function add_query_vars( $qvars ) { $qvars[] = 'MyPlugin'; return $qvars; } function template_redirect_intercept() { global $wp_query; if ( $wp_query-get('MyPlugin') ) { $id = $wp_query-query_vars['MyPlugin']; $this-pushoutput( $id ); exit; } } } } if ( class_exists("MyPlugin") ) { $MyPluginCode = new MyPlugin(); } if ( isset($MyPluginCode) ) { register_activation_hook( __file__, array($MyPluginCode, 'activate') ); add_action( 'admin-init', array(&$MyPluginCode, 'flush_rewrite_rules') ); //add_action( 'init', array(&$MyPluginCode, 'init') ); add_action( 'generate_rewrite_rules', array(&$MyPluginCode, 'createRewriteRules') ); add_action( 'template_redirect', array(&$MyPluginCode, 'template_redirect_intercept') ); // add_filter( 'query_vars', array(&$MyPluginCode, 'add_query_vars') ); }

  • form validation with jquery

    - by kalpaitch
    I am having some issues with a jQuery form validation pluggin. Below is the code which executes on document.ready() $("#register").validate({ rules: { usernameREG: { required: true, remote: "PHP/checkUsr.php", minlength: 4} fnameREG: { required: true} lnameREG: { required: true} password1REG: { required: true, minlength: 4} password2REG: { equalTo: "#password1REG", required: true} emailREG: { required: true, email: true} telREG: { required: true, rangelength: [9, 13]} } }); Even without the 'rules' parameters this function does not trigger. It also stops all the proceeding jquery functions which are triggered on document.ready()

  • Code cleanup in netbeans

    - by Kapsh
    Is there something similar to the Eclipse cleanup rules ((Preferences Java Code Style Clean Up) in NetBeans? The cleanup rules in eclipse will allow you to clean things up like organizing imports, removing unnecessary casts, adding missing override annotations etc. Also can you do that on a whole set of classes/packages instead of individual classes?

  • How is parsing phase in a compiler different from a rule engine ?

    - by abhinav
    Hi, I have a rough understanding of how the compilers work (I mean languages, grammars, lexical analysis, parsing etc). The rule engines have various rules and associated action, just like you have rules in the grammars and you can associate actions with them in parser-generator tools like ANTLR. So I am a bit confused on how to differentiate between these two. Could anyone give a clearer, more formal explanation for the differences ? Thanks, Abhinav.
