  • MySQL: Creating table with FK error (errno 150)

    - by Peter Bailey
    I've tried searching on this error and nothing I've found helps me, so I apologize in advance if this is a duplicate and I'm just too dumb to find it. I've created a model with MySQL Workbench and am now attempting to install it to a mysql server. Using File Export Forward Engineer SQL CREATE Script... it outputs a nice big file for me, with all the settings I ask for. I switch over to MySQL GUI Tools (the Query Browser specifically) and load up this script (note that I'm going form one official MySQL tool to another). However, when I try to actually execute this file, I get the same error over and over SQLSTATE[HY000]: General error: 1005 Can't create table './srs_dev/location.frm' (errno: 150) "OK", I say to myself, something is wrong with the location table. So I check out the definition in the output file. SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0; SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0; SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL'; -- ----------------------------------------------------- -- Table `state` -- ----------------------------------------------------- DROP TABLE IF EXISTS `state` ; CREATE TABLE IF NOT EXISTS `state` ( `state_id` INT NOT NULL AUTO_INCREMENT , `iso_3166_2_code` VARCHAR(2) NOT NULL , `name` VARCHAR(60) NOT NULL , PRIMARY KEY (`state_id`) ) ENGINE = InnoDB; -- ----------------------------------------------------- -- Table `brand` -- ----------------------------------------------------- DROP TABLE IF EXISTS `brand` ; CREATE TABLE IF NOT EXISTS `brand` ( `brand_id` INT UNSIGNED NOT NULL AUTO_INCREMENT , `name` VARCHAR(45) NOT NULL , `domain` VARCHAR(45) NOT NULL , `manager_name` VARCHAR(100) NULL , `manager_email` VARCHAR(255) NULL , PRIMARY KEY (`brand_id`) ) ENGINE = InnoDB; -- ----------------------------------------------------- -- Table `location` -- ----------------------------------------------------- DROP TABLE IF EXISTS `location` ; CREATE TABLE IF NOT EXISTS `location` ( `location_id` INT UNSIGNED NOT NULL AUTO_INCREMENT , `name` VARCHAR(255) NOT NULL , `address_line_1` VARCHAR(255) NULL , `address_line_2` VARCHAR(255) NULL , `city` VARCHAR(100) NULL , `state_id` TINYINT UNSIGNED NULL DEFAULT NULL , `postal_code` VARCHAR(10) NULL , `phone_number` VARCHAR(20) NULL , `fax_number` VARCHAR(20) NULL , `lat` DECIMAL(9,6) NOT NULL , `lng` DECIMAL(9,6) NOT NULL , `contact_url` VARCHAR(255) NULL , `brand_id` TINYINT UNSIGNED NOT NULL , `summer_hours` VARCHAR(255) NULL , `winter_hours` VARCHAR(255) NULL , `after_hours_emergency` VARCHAR(255) NULL , `image_file_name` VARCHAR(100) NULL , `manager_name` VARCHAR(100) NULL , `manager_email` VARCHAR(255) NULL , `created_date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP , PRIMARY KEY (`location_id`) , CONSTRAINT `fk_location_state` FOREIGN KEY (`state_id` ) REFERENCES `state` (`state_id` ) ON DELETE NO ACTION ON UPDATE NO ACTION, CONSTRAINT `fk_location_brand` FOREIGN KEY (`brand_id` ) REFERENCES `brand` (`brand_id` ) ON DELETE NO ACTION ON UPDATE NO ACTION) ENGINE = InnoDB; CREATE INDEX `fk_location_state` ON `location` (`state_id` ASC) ; CREATE INDEX `fk_location_brand` ON `location` (`brand_id` ASC) ; CREATE INDEX `idx_lat` ON `location` (`lat` ASC) ; CREATE INDEX `idx_lng` ON `location` (`lng` ASC) ; Looks ok to me. I surmise that maybe something is wrong with the Query Browser, so I put this file on the server and try to load it this way ] mysql -u admin -p -D dbname < path/to/create_file.sql And I get the same error. So I start to Google this issue and find all kinds of accounts that talk about an error with InnoDB style tables that fail with foreign keys, and the fix is to add "SET FOREIGN_KEY_CHECKS=0;" to the SQL script. Well, as you can see, that's already part of the file that MySQL Workbench spat out. So, my question is then, why is this not working when I'm doing what I think I'm supposed to be doing? Version Info: # MySQL: 5.0.45 GUI Tools: 1.2.17 Workbench: 5.0.30

  • What are good CLI tools for JSON?

    - by jasonmp85
    General Problem Though I may be diagnosing the root cause of an event, determining how many users it affected, or distilling timing logs in order to assess the performance and throughput impact of a recent code change, my tools stay the same: grep, awk, sed, tr, uniq, sort, zcat, tail, head, join, and split. To glue them all together, Unix gives us pipes, and for fancier filtering we have xargs. If these fail me, there's always perl -e. These tools are perfect for processing CSV files, tab-delimited files, log files with a predictable line format, or files with comma-separated key-value pairs. In other words, files where each line has next to no context. XML Analogues I recently needed to trawl through Gigabytes of XML to build a histogram of usage by user. This was easy enough with the tools I had, but for more complicated queries the normal approaches break down. Say I have files with items like this: <foo user="me"> <baz key="zoidberg" value="squid" /> <baz key="leela" value="cyclops" /> <baz key="fry" value="rube" /> </foo> And let's say I want to produce a mapping from user to average number of <baz>s per <foo>. Processing line-by-line is no longer an option: I need to know which user's <foo> I'm currently inspecting so I know whose average to update. Any sort of Unix one liner that accomplishes this task is likely to be inscrutable. Fortunately in XML-land, we have wonderful technologies like XPath, XQuery, and XSLT to help us. Previously, I had gotten accustomed to using the wonderful XML::XPath Perl module to accomplish queries like the one above, but after finding a TextMate Plugin that could run an XPath expression against my current window, I stopped writing one-off Perl scripts to query XML. And I just found out about XMLStarlet which is installing as I type this and which I look forward to using in the future. JSON Solutions? So this leads me to my question: are there any tools like this for JSON? It's only a matter of time before some investigation task requires me to do similar queries on JSON files, and without tools like XPath and XSLT, such a task will be a lot harder. If I had a bunch of JSON that looked like this: { "firstName": "Bender", "lastName": "Robot", "age": 200, "address": { "streetAddress": "123", "city": "New York", "state": "NY", "postalCode": "1729" }, "phoneNumber": [ { "type": "home", "number": "666 555-1234" }, { "type": "fax", "number": "666 555-4567" } ] } And wanted to find the average number of phone numbers each person had, I could do something like this with XPath: fn:avg(/fn:count(phoneNumber)) Questions Are there any command-line tools that can "query" JSON files in this way? If you have to process a bunch of JSON files on a Unix command line, what tools do you use? Heck, is there even work being done to make a query language like this for JSON? If you do use tools like this in your day-to-day work, what do you like/dislike about them? Are there any gotchas? I'm noticing more and more data serialization is being done using JSON, so processing tools like this will be crucial when analyzing large data dumps in the future. Language libraries for JSON are very strong and it's easy enough to write scripts to do this sort of processing, but to really let people play around with the data shell tools are needed. Related Questions Grep and Sed Equivalent for XML Command Line Processing Is there a query language for JSON? JSONPath or other XPath like utility for JSON/Javascript; or Jquery JSON

  • Where do I start ?

    - by Panthe
    Brief History: Just graduated high school, learned a bit of python and C++, have no friends with any helpful computer knowledge at all. Out of anyone i met in my school years I was probably the biggest nerd, but no one really knew. I consider my self to have a vast amount of knowledge on computers and tech then the average person. built/fixed tons of computers, and ability to troubleshoot pretty much any problem I came across. Now that high school is over, Ive really been thinking about my career. Loving, living computers for the past 15 years of my life I decided to take my ability's and try to learn computer programming, why I didn't start earlier I don't know, seems to be big mistake on my part... Doing some research I concluded that Python was the first programming language I should learn, since it was high level and easier to understand then C++ and Java. I also knew that to become good at what I did I needed to know more then just 2 or 3 languages, which didn't seem like a big problem considering once I learned the way Python worked, mainly syntax changed, and the rest would come naturally. I watched a couple of youtube videos, downloaded some book pdf's and snooped around from some tutorials here and there to get the hang of what to do. A two solid weeks had passed of trying to understand the syntax, create small programs that used the basic functions and understanding how it worked, I think i have got the hang of it. It breaks down into what ive been dealing with all this time (although i kinda knew) is that, input,output, loops, functions and other things derived from 0's and 1's storing data and recalling it, ect. (A VERY BASIC IDEA). Ive been able to create small programs, Hangman, file storing, temperature conversion, Caeser Cipher decode/encoding, Fibonacci Sequence and more, which i can create and understand how each work. Being 2 weeks into this, I have learned alot. Nothing at all compared to what i should be learning in the years to come if i get a grip on what I'm doing. While doing these programs I wont stop untill I've done doing a practice problem on a book, which embarresing enough will take me a couple hour depending on the complexity of it. I absolutly will not put aside the challenge until its complete, WHICH CAN BE EXTREMELY DRAINING, ive tried most problems without cheating and reached success, which makes me feel extremely proud of my self after completing something after much trial and error. After all this I have met the demon, alogrithm's which seem to be key to effiecent code. I cant seem to rap my head around some of the computer codes people put out there using numbers, and sometimes even basic functions, I have been able to understand them after a while but i know there are alot more complex things to come, considering my self smart, functions that require complex codes, actually hurt my brain. NOTHING EVER IN LIFE HURT MY BRAIN....... not even math classes in highschool, trying to understand some of the stuff people put out there makes me feel like i have a mental disadvantage lol... i still walk forward though, crossing my fingers that the understanding will come with time. Sorry if is this is long i just wish someone takes all these things into consideration when answering my question. even through all these downsides im still pushing through and continuing to try and get good at this, i know reading these tutorials wont make me any good unless i can become creative and make my own, understand other peoples programs, so this leads me to the simple question i could have asked in the beginning..... WHERE IN THE WORLD DO I START ? Ive been trying to find out how to understand some of the open source projects, how i can work with experianced coders to learn from them and help them, but i dont think thats even possible by the way how far people's knowledge is compared to me, i have no freinds who i can learn from, can someone help me and guide me into the right direction.. i have a huge motivation to get good at coding, anything information would be extremely helpful

  • Perl not closing TCP sockets if clients are no longer connected?

    - by LM
    The purpose of the application is to listen for a specific UDP multicast and then to forward the data to any TCP clients connected to the server. The code works fine, but I have a problem with the sockets not closing after the TCP clients disconnects. A socketsniffer utility shows the the sockets remain open and all the UDP data continues to be forwarded to the clients. The problem I believe is with the "if ($write-connected())" block as it always return true, even if the TCP client is no longer connected. I use standard Windows Telnet to connect to the server and to see the data. When I close telnet, the TCP socket is suppose to close on the server. Any reason why connected() show the connections as active even if they are not? Also, what alternative should I use then? Code: #!/usr/bin/perl use IO::Socket::Multicast; use IO::Socket; use IO::Select; my $tcp_port = "4550"; my $tcp_socket = IO::Socket::INET->new( Listen => SOMAXCONN, LocalAddr => '0.0.0.0', LocalPort => $tcp_port, Proto => 'tcp', ReuseAddr => 1, ); use Socket qw(IPPROTO_TCP TCP_NODELAY); setsockopt( $tcp_socket, IPPROTO_TCP, TCP_NODELAY, 1); use constant GROUP => '239.2.0.81'; use constant PORT => '6550'; my $udp_socket= IO::Socket::Multicast->new(Proto=>'udp',LocalPort=>PORT); $udp_socket->mcast_add(GROUP) || die "Couldn't set group: $!\n"; my $read_select = IO::Select->new(); my $write_select = IO::Select->new(); $read_select->add($tcp_socket); $read_select->add($udp_socket); ## Loop forever, reading data from the UDP socket and writing it to the ## TCP socket(s). while (1) { ## No timeout specified (see docs for IO::Select). This will block until a TCP ## client connects or we have data. my @read = $read_select->can_read(); foreach my $read (@read) { if ($read == $tcp_socket) { ## Handle connect from TCP client. Note that UDP connections are ## stateless (no accept necessary)... my $new_tcp = $read->accept(); $write_select->add($new_tcp); } elsif ($read == $udp_socket) { ## Handle data received from UDP socket... my $recv_buffer; $udp_socket->recv($recv_buffer, 1024, undef); ## Write the data read from UDP out to the TCP client(s). Again, no ## timeout. This will block until a TCP socket is writable. my @write = $write_select->can_write(); foreach my $write (@write) { ## Make sure the socket is still connected before writing. if ($write->connected()) { $write->send($recv_buffer); } else { $write_select->remove($write); close $write; } } } } }

  • Packets marked by iptables only sent to the correct routing table sometimes

I am testing ipchicken.com and walmart.com via links, from the same user, same shell. walmart.com appears to use the VPN; ipchicken.com does not. Any help appreciated. Will send 0.5 bitcoins to answerer who makes this fixed.

  • How can I tell the size of my app during development?

    - by Newbyman
    My programming decissions are directly related to how much room I have left, or worse perhaps how much I need to shave off in order to get up the 10mb limit. I have read that Apple has quietly increased the 3G & Edge download limit from 10mb up to 20mb in preparation for the iPad in April. Either way, my real question is how can I gauge a rough estimate of how large my app will end while I'm still in the development phase? Is the file size of my development folder roughly 1 to 1 ratio? Is the compressed file size of my development a better approximation? My .xcodeproj file is only a couple hundred kB, but the size of my folder is 11.8 MB. I have a .sqlite database, less than 20 small png images and a Settings.Bundle. The rest are unknown Xcode files related to build, build for iphoneOS, simulator etc.... My source code is rather large with around 1000 lines in most of the major controllers, all in all around 48 .h&.m files. But my classes folder inside my development folder is less than 800kb. Digging around inside my Build file, there is lots of iphone simulator files and debugging files which I don't think will contribute to the final product. The Application file states that it is around 2.3 MB. However, this is such a large difference from the 11.8 MB, I have to wonder if this is just another piece of the equation. I have the app on the my device, I'm in the testing phase. Therefore, I though that I would try to see how large the working version was on the device by checking in iTunes, however my development app is visible on the right-hand the application's iphone screen, but no information about the app most importantly its size. I also checked in Organizer, I used the lower portion of the screen-(Applications), found my application and selected the drop down arrow which gave my "Application Data" and a download arrow button to the right to save a file on my desktop, named with the unique AppleID. Inside the folder it had three folders-(documents, library, tmp) the documents had a copy of my .sqlite database, the library a few more files but not anything obvious or of size, and the tmp was empty. All in all the entire folder was only 164kb-which tells me that this is not the right place to find the size either. I understand that the size is considered to be the size of my binary plus all the additional files and images that I have add. Does anyone have a effective way of guaging how large the binary is or the relating the development folder size to what the final App Store application size will end up. I know that questions have been posted with similar aspects, but I could not find any answered post that really described...what files, or how to determine size specifically. I know that this question looks like a book, but I just wanted to be specific in conveying exactly what I'm looking for and the attempts thus far. *Note all files are unzipped and still in regular working Xcode order of a single app with no brought-in builds or referenced projects. I'm sure that this is straight forward, I just don't know where to look?

  • OpenVPN and PPTP on XEN VPS

    - by amiv
    I have Debian based system (Ubuntu 11.10) on XEN VPS. I've installed OpenVPN and works great. I need to install PPTP too, so did it and clients can connect, but they have no internet on client side. If I connect to VPN over PPTP I can ping and access to only my VPS by its IP, but ony that. There's no "internet" on client side. It looks it's not DNS problems (I'm using 8.8.8.8) because I can't ping known IPs. I bet the solution is simple, but don't have any idea. Any guess? /etc/pptpd.conf option /etc/ppp/pptpd-options logwtmp localip 46.38.xx.xx remoteip 10.1.0.1-10 /etc/ppp/pptpd-options name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 ms-dns 8.8.8.8 ms-dns 8.8.4.4 proxyarp nodefaultroute lock nobsdcomp /etc/ppp/ip-up [...] ifconfig ppp0 mtu 1400 /etc/sysctl.conf [...] net.ipv4.ip_forward=1 Command which I run: iptables -t nat -A POSTROUTING -j SNAT --to-source 46.38.xx.xx (IP of my VPS) The client can connect, first one gets IP 10.1.0.1 and DNS from Google. I bet it's iptables problem, am I right? I'm iptables noob and I don't have idea what's wrong. And here's the ifconfig and route command before client connect via PPTP: root@vps3780:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default xx.xx.tel.ru 0.0.0.0 UG 100 0 0 eth0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 46.38.xx.0 * 255.255.255.0 U 0 0 0 eth0 root@vps3780:~# ifconfig eth0 Link encap:Ethernet HWaddr 00:16:3e:56:xx:xx inet addr:46.38.xx.xx Bcast:0.0.0.0 Mask:255.255.255.0 inet6 addr: fe80::216:xx:xx:dfb6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:22671 errors:0 dropped:81 overruns:0 frame:0 TX packets:2266 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1813358 (1.8 MB) TX bytes:667626 (667.6 KB) Interrupt:24 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:100 errors:0 dropped:0 overruns:0 frame:0 TX packets:100 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:10778 (10.7 KB) TX bytes:10778 (10.7 KB) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:602 errors:0 dropped:0 overruns:0 frame:0 TX packets:612 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:90850 (90.8 KB) TX bytes:418904 (418.9 KB) And here's the ifconfig and route command after client connect via PPTP: root@vps3780:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default xx.xx.tel.ru 0.0.0.0 UG 100 0 0 eth0 10.1.0.1 * 255.255.255.255 UH 0 0 0 ppp0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 46.38.xx.0 * 255.255.255.0 U 0 0 0 eth0 root@vps3780:~# ifconfig eth0 Link encap:Ethernet HWaddr 00:16:3e:56:xx:xx inet addr:46.38.xx.xx Bcast:0.0.0.0 Mask:255.255.255.0 inet6 addr: fe80::216:xx:xx:dfb6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:22989 errors:0 dropped:82 overruns:0 frame:0 TX packets:2352 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1841310 (1.8 MB) TX bytes:678456 (678.4 KB) Interrupt:24 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:112 errors:0 dropped:0 overruns:0 frame:0 TX packets:112 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:12102 (12.1 KB) TX bytes:12102 (12.1 KB) ppp0 Link encap:Point-to-Point Protocol inet addr:46.38.xx.xx P-t-P:10.1.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:66 errors:0 dropped:0 overruns:0 frame:0 TX packets:15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:10028 (10.0 KB) TX bytes:660 (660.0 B) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:602 errors:0 dropped:0 overruns:0 frame:0 TX packets:612 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:90850 (90.8 KB) TX bytes:418904 (418.9 KB) And ugly iptables --list output: root@vps3780:~# iptables --list Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- 10.8.0.0/24 anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable ACCEPT all -- 10.1.0.0/24 anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- 10.1.0.0/24 anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- 10.8.0.0/24 anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable And ugly iptables -t nat -L output: root@vps3780:~# iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination SNAT all -- 10.8.0.0/24 anywhere to:46.38.xx.xx MASQUERADE all -- 10.1.0.0/24 anywhere SNAT all -- 10.1.0.0/24 anywhere to:46.38.xx.xx SNAT all -- 10.8.0.0/24 anywhere to:46.38.xx.xx SNAT all -- 10.1.0.0/24 anywhere to:46.38.xx.xx MASQUERADE all -- anywhere anywhere SNAT all -- anywhere anywhere to:46.38.xx.xx SNAT all -- 10.8.0.0/24 anywhere to:46.38.xx.xx MASQUERADE all -- anywhere anywhere MASQUERADE all -- 10.1.0.0/24 anywhere MASQUERADE all -- anywhere anywhere MASQUERADE all -- 10.1.0.0/24 anywhere As I said - OpenVPN works very good. 10.8.0.0/24 for OpenVPN (on tun0). PPTP won't work. 10.1.0.0/24 for PPTP (on ppp0). Clients can connect, but they haven't "internet". Any suggestions will be appreciated. Second whole day fighting with no results. EDIT: iptables -t filter -F - it resolved my problem :-)

  • What is the best way to solve an Objective-C namespace collision?

    - by Mecki
    Objective-C has no namespaces; it's much like C, everything is within one global namespace. Common practice is to prefix classes with initials, e.g. if you are working at IBM, you could prefix them with "IBM"; if you work for Microsoft, you could use "MS"; and so on. Sometimes the initials refer to the project, e.g. Adium prefixes classes with "AI" (as there is no company behind it of that you could take the initials). Apple prefixes classes with NS and says this prefix is reserved for Apple only. So far so well. But appending 2 to 4 letters to a class name in front is a very, very limited namespace. E.g. MS or AI could have an entirely different meanings (AI could be Artificial Intelligence for example) and some other developer might decide to use them and create an equally named class. Bang, namespace collision. Okay, if this is a collision between one of your own classes and one of an external framework you are using, you can easily change the naming of your class, no big deal. But what if you use two external frameworks, both frameworks that you don't have the source to and that you can't change? Your application links with both of them and you get name conflicts. How would you go about solving these? What is the best way to work around them in such a way that you can still use both classes? In C you can work around these by not linking directly to the library, instead you load the library at runtime, using dlopen(), then find the symbol you are looking for using dlsym() and assign it to a global symbol (that you can name any way you like) and then access it through this global symbol. E.g. if you have a conflict because some C library has a function named open(), you could define a variable named myOpen and have it point to the open() function of the library, thus when you want to use the system open(), you just use open() and when you want to use the other one, you access it via the myOpen identifier. Is something similar possible in Objective-C and if not, is there any other clever, tricky solution you can use resolve namespace conflicts? Any ideas? Update: Just to clarify this: answers that suggest how to avoid namespace collisions in advance or how to create a better namespace are certainly welcome; however, I will not accept them as the answer since they don't solve my problem. I have two libraries and their class names collide. I can't change them; I don't have the source of either one. The collision is already there and tips on how it could have been avoided in advance won't help anymore. I can forward them to the developers of these frameworks and hope they choose a better namespace in the future, but for the time being I'm searching a solution to work with the frameworks right now within a single application. Any solutions to make this possible?

  • How do I launch a WPF app from command.com. I'm getting a FontCache error.

    - by jttraino
    I know this is not ideal, but my constraint is that I have a legacy application written in Clipper. I want to launch a new, WinForms/WPF application from inside the application (to ease transition). This legacy application written in Clipper launches using: SwpRunCmd("C:\MyApp\MyBat.bat",0) The batch file contains something like this command: C:\PROGRA~1\INTERN~1\iexplore "http://QASVR/MyApp/AppWin/MyCompany.MyApp.AppWin.application#MyCompany.MyApp.AppWin.application" It is launching a WinForms/WPF app that is we deploy via ClickOnce. Everything has been going well until we introduced WPF into the application. We were able to easily launch from the legacy application. Since we have introduced WPF, however, we have the following behavior. If we launch via the Clipper application first, we get an exception when launching the application. The error text is: The type initializer for 'System.Windows.FrameworkElement' threw an exception. at System.Windows.FrameworkElement..ctor() at System.Windows.Controls.Panel..ctor() at System.Windows.Controls.DockPanel..ctor() at System.Windows.Forms.Integration.AvalonAdapter..ctor(ElementHost hostControl) at System.Windows.Forms.Integration.ElementHost..ctor() at MyCompany.MyApp.AppWin.Main.InitializeComponent() at MyCompany.MyApp.AppWin.Main..ctor(String[] args) at MyCompany.MyApp.AppWin.Program.Main(String[] args) The type initializer for 'System.Windows.Documents.TextElement' threw an exception. at System.Windows.FrameworkElement..cctor() The type initializer for 'System.Windows.Media.FontFamily' threw an exception. at System.Windows.Media.FontFamily..ctor(String familyName) at System.Windows.SystemFonts.get_MessageFontFamily() at System.Windows.Documents.TextElement..cctor() The type initializer for 'MS.Internal.FontCache.Util' threw an exception. at MS.Internal.FontCache.Util.get_WindowsFontsUriObject() at System.Windows.Media.FontFamily.PreCreateDefaultFamilyCollection() at System.Windows.Media.FontFamily..cctor() Invalid URI: The format of the URI could not be determined. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString, UriKind uriKind) at MS.Internal.FontCache.Util..cctor() If we launch the application via the URL (in IE) or via the icon on the desktop first, we do not get the exception and application launches as expected. The neat thing is that whatever we launch with first determines whether the app will launch at all. So, if we launch with legacy first, it breaks right away and we can't get the app to run even if we launch with the otherwise successful URL or icon. To get it to work, we have to logout and log back in and start it from the URL or icon. If we first use the URL or the icon, we have no problem launching from the legacy application from that point forward (until we logout and come back in). One other piece of information is that we are able to simulate the problem in the following fashion. If we enter a command prompt using "cmd.exe" and execute a statement to launch from a URL, we are successful. If, however, we enter a command prompt using "command.com" and we execute that same statement, we experience the breaking behavior. We assume it is because the legacy application in Clipper uses the equivalent of command.com to create the shell to spawn the other app. We have tried a bunch of hacks like having command.com run cmd.exe or psexec and then executing, but nothing seems to work. We have some ideas for workarounds (like making the app launch on startup so we force the successful launch from a URL, making all subsequent launches successful), but they all are sub-optimal even though we have a great deal of control over our workstations. To reduce the chance that this is related to permissions, we have given the launching account administrative rights (as well as non-administrative rights in case that made a difference). Any ideas would be greatly-appreciate. Like I said, we have some work arounds, but I would love to avoid them. Thanks!

  • Neo4j increasing latency as SKIP increases on Cypher query + REST API

    - by voldomazta
    My setup: Java(TM) SE Runtime Environment (build 1.7.0_45-b18) Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode) Neo4j 2.0.0-M06 Enterprise First I made sure I warmed up the cache by executing the following: START n=node(*) RETURN COUNT(n); START r=relationship(*) RETURN count(r); The size of the table is 63,677 nodes and 7,169,995 relationships Now I have the following query: START u1=node:node_auto_index('uid:39') MATCH (u1:user)-[w:WANTS]->(c:card)<-[h:HAS]-(u2:user) WHERE u2.uid <> 39 WITH u2.uid AS uid, (CASE WHEN w.qty < h.qty THEN w.qty ELSE h.qty END) AS have RETURN uid, SUM(have) AS total ORDER BY total DESC SKIP 0 LIMIT 25 This UID has about 40k+ results that I want to be able to put a pagination to. The initial skip was around 773ms. I tried page 2 (skip 25) and the latency was around the same even up to page 500 it only rose up to 900ms so I didn't really bother. Now I tried some fast forward paging and jumped by thousands so I did 1000, then 2000, then 3000. I was hoping the ORDER BY arrangement will already have been cached by Neo4j and using SKIP will just move to that index in the result and wont have to iterate through each one again. But for each thousand skip I made the latency increased by alot. It's not just cache warming because for one I already warmed up the cache and two, I tried the same skip a couple of times for each skip and it yielded the same results: SKIP 0: 773ms SKIP 1000: 1369ms SKIP 2000: 2491ms SKIP 3000: 3899ms SKIP 4000: 5686ms SKIP 5000: 7424ms Now who the hell would want to view 5000 pages of results? 40k even?! :) Good point! I will probably put a cap on the maximum results a user can view but I was just curious about this phenomenon. Will somebody please explain why Neo4j seems to be re-iterating through stuff which appears to be already known to it? Here is my profiling for the 0 skip: ==> ColumnFilter(symKeys=["uid", " INTERNAL_AGGREGATE65c4d6a2-1930-4f32-8fd9-5e4399ce6f14"], returnItemNames=["uid", "total"], _rows=25, _db_hits=0) ==> Slice(skip="Literal(0)", _rows=25, _db_hits=0) ==> Top(orderBy=["SortItem(Cached( INTERNAL_AGGREGATE65c4d6a2-1930-4f32-8fd9-5e4399ce6f14 of type Any),false)"], limit="Add(Literal(0),Literal(25))", _rows=25, _db_hits=0) ==> EagerAggregation(keys=["uid"], aggregates=["( INTERNAL_AGGREGATE65c4d6a2-1930-4f32-8fd9-5e4399ce6f14,Sum(have))"], _rows=41659, _db_hits=0) ==> ColumnFilter(symKeys=["have", "u1", "uid", "c", "h", "w", "u2"], returnItemNames=["uid", "have"], _rows=146826, _db_hits=0) ==> Extract(symKeys=["u1", "c", "h", "w", "u2"], exprKeys=["uid", "have"], _rows=146826, _db_hits=587304) ==> Filter(pred="((NOT(Product(u2,uid(0),true) == Literal(39)) AND hasLabel(u1:user(0))) AND hasLabel(u2:user(0)))", _rows=146826, _db_hits=146826) ==> TraversalMatcher(trail="(u1)-[w:WANTS WHERE (hasLabel(NodeIdentifier():card(1)) AND hasLabel(NodeIdentifier():card(1))) AND true]->(c)<-[h:HAS WHERE (NOT(Product(NodeIdentifier(),uid(0),true) == Literal(39)) AND hasLabel(NodeIdentifier():user(0))) AND true]-(u2)", _rows=146826, _db_hits=293696) And for the 5000 skip: ==> ColumnFilter(symKeys=["uid", " INTERNAL_AGGREGATE99329ea5-03cd-4d53-a6bc-3ad554b47872"], returnItemNames=["uid", "total"], _rows=25, _db_hits=0) ==> Slice(skip="Literal(5000)", _rows=25, _db_hits=0) ==> Top(orderBy=["SortItem(Cached( INTERNAL_AGGREGATE99329ea5-03cd-4d53-a6bc-3ad554b47872 of type Any),false)"], limit="Add(Literal(5000),Literal(25))", _rows=5025, _db_hits=0) ==> EagerAggregation(keys=["uid"], aggregates=["( INTERNAL_AGGREGATE99329ea5-03cd-4d53-a6bc-3ad554b47872,Sum(have))"], _rows=41659, _db_hits=0) ==> ColumnFilter(symKeys=["have", "u1", "uid", "c", "h", "w", "u2"], returnItemNames=["uid", "have"], _rows=146826, _db_hits=0) ==> Extract(symKeys=["u1", "c", "h", "w", "u2"], exprKeys=["uid", "have"], _rows=146826, _db_hits=587304) ==> Filter(pred="((NOT(Product(u2,uid(0),true) == Literal(39)) AND hasLabel(u1:user(0))) AND hasLabel(u2:user(0)))", _rows=146826, _db_hits=146826) ==> TraversalMatcher(trail="(u1)-[w:WANTS WHERE (hasLabel(NodeIdentifier():card(1)) AND hasLabel(NodeIdentifier():card(1))) AND true]->(c)<-[h:HAS WHERE (NOT(Product(NodeIdentifier(),uid(0),true) == Literal(39)) AND hasLabel(NodeIdentifier():user(0))) AND true]-(u2)", _rows=146826, _db_hits=293696) The only difference is the LIMIT clause on the Top function. I hope we can make this work as intended, I really don't want to delve into doing an embedded Neo4j + my own Jetty REST API for the web app.

  • MySQL access classes in PHP

    - by Mike
    I have a connection class for MySQL that looks like this: class MySQLConnect { private $connection; private static $instances = 0; function __construct() { if(MySQLConnect::$instances == 0) { //Connect to MySQL server $this->connection = mysql_connect(MySQLConfig::HOST, MySQLConfig::USER, MySQLConfig::PASS) or die("Error: Unable to connect to the MySQL Server."); MySQLConnect::$instances = 1; } else { $msg = "Close the existing instance of the MySQLConnector class."; die($msg); } } public function singleQuery($query, $databasename) { mysql_select_db(MySQLConfig::DB, $this->connection) or die("Error: Could not select database " . MySQLConfig::DB . " from the server."); $result = mysql_query($query) or die('Query failed.'); return $result; } public function createResultSet($query, $databasename) { $rs = new MySQLResultSet($query, MySQLConfig::DB, $this->connection ) ; return $rs; } public function close() { MySQLConnect::$instances = 0; if(isset($this->connection) ) { mysql_close($this->connection) ; unset($this->connection) ; } } public function __destruct() { $this->close(); } } The MySQLResultSet class looks like this: class MySQLResultSet implements Iterator { private $query; private $databasename; private $connection; private $result; private $currentRow; private $key = 0; private $valid; public function __construct($query, $databasename, $connection) { $this->query = $query; //Select the database $selectedDatabase = mysql_select_db($databasename, $connection) or die("Error: Could not select database " . $this->dbname .

Could anybody recommend an alternative method if it is bad? Thank-you.

  • slow DNS resolution

    - by Ehsan
    I have a DNS server that resolves all queries for an internal group of servers. It is a bind on CentOS 5.5 (same as RHEL5) and I have set it up to allow recursion and resolve direction without any forwarders. The problem I am facing is that it takes a freakishly long amount of time to resolve a name for the first time. (in the magnitudes of 20 sec) This causes clients to give timeout. When I set it to forward all to Google's public DNS, i.e. 8.8.8.8+8.8.4.4, it works very nicely (within a second). I tried monitoring the traffic on the net to see why it is doing this: [root@ns1 ~]# tcpdump -nnvvvA -s0 udp tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 23:06:36.137797 IP (tos 0x0, ttl 64, id 35903, offset 0, flags [none], proto: UDP (17), length: 60) 172.17.1.10.36942 > 172.17.1.4.53: [udp sum ok] 19773+ A? www.paypal.com.

  • ASA 5505 Vlan question

    - by Wayne
    I am setting up a cisco asa 5505 with the base license. I can communicate from inside-outside, outside-inside, inside-home, which is my desired traffic security.

  • dynamically include zipfilesets into a WAR

    - by Konstantin
    hi all - a bit of clumsy situation but for the moment we cannot migrate to more straight-forward project layout. We have a project called myServices and it has 2 source folders (yes, I know, but that's the way it is for now) - I'm trying to make build process a bit more flexible so we now have a property called artifact.names that will be parsed by generic build.xml and based on name, it will call either jar or war task, eg. myService-war will create a WAR file with the following zipfilesets included there: myService-war-classes, myService-war-web-inf, myService-war-meta-inf. I want to add a bit more flexibility, and allow having additional zipfilesets, eg. myService-war-etc-1,2 etc - so these will be picked up by the package target automatically. I cannot use "if" inside war target, and also ${ant.refid:myService-war-classes} property is not resolved, so I'm kind of stuck at the moment with my options - how do I dynamically include a zipfileset into a WAR? You can refer to fileset by id, but it MUST be defined then, eg. you can't have it optional on project level. Thank you. Some build.xml snippets: <target name="archive"> <for list="${artifact.names}" param="artifact"> <sequential> <echo>Packaging artifact @{artifact} of project ${project.name}</echo> <property name="display.@{artifact}.packaging" refid="@{artifact}.packaging" /> <echo>${display.@{artifact}.packaging}</echo> <propertyregex property="@{artifact}.archive.type" input="@{artifact}" regexp="([a-zA-Z0-9]*)(\-)([ejw]ar)" select="\3" casesensitive="false"/> <propertyregex property="@{artifact}.base.name" input="@{artifact}" regexp="([a-zA-Z0-9]*)(\-)([ejw]ar)" select="\1" casesensitive="false"/> <echo>${@{artifact}.archive.type}</echo> <if> <then> <war destfile="${jar.dir}/${@{artifact}.base.name}.war" compress="true" needxmlfile="false"> <resources refid="@{artifact}.packaging" /> <zipfileset refid="@{artifact}-classes" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-meta-inf" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-web-inf" erroronmissingdir="false" /> <!-- Additional zipfilesets to package --> <zipfileset refid="@{artifact}-etc-2" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-3" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-4" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-5" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-6" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-7" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-8" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-9" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-10" erroronmissingdir="false" /> </war> </then> <!-- Generic JAR packaging --> <else> <jar destfile="${jar.dir}/@{artifact}.jar" compress="true"> <resources refid="@{artifact}.packaging" /> <zipfileset refid="@{artifact}-meta-inf" erroronmissingdir="false" /> </jar> </else> </if> </sequential> </for> </target>

  • DDNS Not Creating Journal (Dhcpd and Named)

    - by user130094
    * EDIT 1 * After monkeying with additional debug logging I see some log entries of interest. 27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: journal rollforward failed: no more 27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: not loaded due to errors. ^^^ If I can remedy the above messages I think I'll be good to go ^^^ * EDIT 2 * Grasping at straws I touched a forward and a reverse zone journal file and restarted named. Boom! Works. Despite documentation stating the files are created automatically and what I have seen before... dunno why but that did the trick. Also re-checked perms on the dir the files live in. As certain as I was, they were correct with named having rw. CentOS 6 (final) dhcpd 4.1.1-P1 named BIND 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6 Basic DHCP and DNS functionality are in place on 192.168.111.2. Clients are assigned addresses as intended and can resolve local DNS names as well as Internet names. My problem is that named's zone journal files are not created. chroot: /var/named/chroot I tried placing the zone files in various directories (/var/named/data, /var/named, /var/named/dynamic - no matter which dir with named owning and wide open perms I now get nowhere). Along the way I, at one point, got a permission denied when named tried to create the journal. Resolved the issue by: chown --recursive named:named /var/named chmod --recursive 777 /var/named The journal was then created and here's where things fell apart. I attempted to tame permissions to something more sane and broke it. Once changed and having restarted named it threw an error indicating the journal was out of sync (or something to that affect)... didn't matter since this is a new setup so I deleted it and now it is not recreated. Now though I see no errors in /var/log/messages, my chrooted /var/log/named.log, or chrooted /var/log/named.debug. I increased the debug level with 'rndc trace' - no love. Increased trace to 10, still nothing. SELinux is disabled...

  • Using GA in GUI

    - by AlexT
    Sorry if this isn't clear as I'm writing this on a mobile device and I'm trying to make it quick. I've written a basic Genetic Algorithm with a binary encoding (genes) that builds a fitness value and evolves through several iterations using tournament selection, mutation and crossover. As a basic command-line example it seems to work. The problem I've got is with applying a genetic algorithm within a GUI as I am writing a maze-solving program that uses the GA to find a method through a maze. How do I turn my random binary encoded genes and fitness function (add all the binary values together) into a method to control a bot around a maze? I have built a basic GUI in Java consisting of a maze of labels (like a grid) with the available routes being in blue and the walls being in black. To reiterate my GA performs well and contains what any typical GA would (fitness method, get and set population, selection, crossover, etc) but now I need to plug it into a GUI to get my maze running. What needs to go where in order to get a bot that can move in different directions depending on what the GA says? Rough pseudocode would be great if possible As requested, an Individual is built using a separate class (Indiv), with all the main work being done in a Pop class. When a new individual is instantiated an array of ints represent the genes of said individual, with the genes being picked at random from a number between 0 and 1. The fitness function merely adds together the value of these genes and in the Pop class handles selection, mutation and crossover of two selected individuals. There's not much else to it, the command line program just shows evolution over n generations with the total fitness improving over each iteration. EDIT: It's starting to make a bit more sense now, although there are a few things that are bugging me... As Adamski has suggested I want to create an "Agent" with the options shown below. The problem I have is where the random bit string comes into play here. The agent knows where the walls are and has it laid out in a 4 bit string (i.e. 0111), but how does this affect the random 32 bit string? (i.e. 10001011011001001010011011010101) If I have the following maze (x is the start place, 2 is the goal, 1 is the wall): x 1 1 1 1 0 0 1 0 0 1 0 0 0 2 If I turn left I'm facing the wrong way and the agent will move completely off the maze if it moves forward. I assume that the first generation of the string will be completely random and it will evolve as the fitness grows but I don't get how the string will work within a maze. So, to get this straight... The fitness is the result of when the agent is able to move and is by a wall. The genes are a string of 32 bits, split into 16 sets of 2 bits to show the available actions and for the robot to move the two bits need to be passed with four bits from the agent showings its position near the walls. If the move is to go past a wall the move isn't made and it is deemed invalid and if the move is made and if a new wall is found then the fitness goes up. Is that right?

  • RSA encryption/ Decryption in a client server application

    - by user308806
    Hi guys, probably missing something very straight forward on this, but please forgive me, I'm very naive! Have a client server application where the client identifies its self with an RSA encrypted username & password. Unfortunately I'm getting a "bad padding exception: data must start with zero" when i try to decrypt with the public key on the client side. I'm fairly sure the key is correct as I have tested encrypting with public key then decrypting with private key on the client side with no problems at all. Just seems when I transfer it over the connection it messses it up somehow?! Using PrintWriter & BufferedReader on the sockets if thats of importance. EncodeBASE64 & DecodeBASE64 encode byte[] to 64base and vice versa respectively. Any ideas guys?? Client side: Socket connectionToServer = new Socket("127.0.0.1", 7050); InputStream in = connectionToServer.getInputStream(); DataInputStream dis = new DataInputStream(in); int length = dis.readInt(); byte[] data = new byte[length]; // dis.readFully(data); dis.read(data); System.out.println("The received Data*****************************************"); System.out.println("The length of bits "+ length); System.out.println(data); System.out.println("***********************************************************"); Decryption d = new Decryption(); byte [] ttt = d.decrypt(data); System.out.print(data); String ss = new String(ttt); System.out.println("***********************"); System.out.println(ss); System.out.println("************************"); Server Side: in = connectionFromClient.getInputStream(); OutputStream out = connectionFromClient.getOutputStream(); DataOutputStream dataOut = new DataOutputStream(out); LicenseList licenses = new LicenseList(); String ValidIDs = licenses.getAllIDs(); System.out.println(ValidIDs); Encryption enc = new Encryption(); byte[] encrypted = enc.encrypt(ValidIDs); byte[] dd = enc.encrypt(ValidIDs); String tobesent = new String(dd); //byte[] rsult = enc.decrypt(dd); //String tt = String(rsult); System.out.println("The sent data**********************************************"); System.out.println(dd); String temp = new String(dd); System.out.println(temp); System.out.println("*************************************************************"); //BufferedWriter bf = new BufferedWriter(OutputStreamWriter(out)); //dataOut.write(ValidIDs.getBytes().length); dataOut.writeInt(ValidIDs.getBytes().length); dataOut.flush(); dataOut.write(encrypted); dataOut.flush(); System.out.println("********Testing**************"); System.out.println("Here are the ids:::"); System.out.println(licenses.getAllIDs()); System.out.println("**********************"); //bw.write("it is working well\n");

  • ADO program to list members of a large group.

    - by AlexGomez
    Hi everyone, I'm attempting to list all the members in a Active Directory group using ADO. The problem I have is that many of these groups have over 1500 members and ADSI cannot handle more than 1500 items in a multi-valued attribute. Fortunately I came across Richard Muller's wonderful VBScript that handles more than 1500 members at http://www.rlmueller.net/DocumentLargeGroup.htm I modified his code as shown below so that I can list ALL the groups and its memberships in a certain OU. However, I'm keeping getting the exception shown below: "ADODB.Recordset: Item cannot be found in the collection corresponding to the requested name or ordinal." My program appears to get stuck at: strPath = adoRecordset.Fields("ADsPath").Value Set objGroup = GetObject(strPath) All I am doing above is issuing the query to get back a recordset consisting of the ADsPath for each group in the OU. It then walks through the recordset and grabs the ADsPath for the first group and store its in a variable named strPath; we then use the value of that variable to bind to the group account for that group. It really should work! Any idea why the code below doesn't work for me? Any pointers will be great appreciated. Thanks. Option Explicit Dim objRootDSE, strDNSDomain, adoCommand Dim adoConnection, strBase, strAttributes Dim strFilter, strQuery, adoRecordset Dim strDN, intCount, blnLast, intLowRange Dim intHighRange, intRangeStep, objField Dim objGroup, objMember, strName ' Determine DNS domain name.

  • Help with OpenVPN setup on Windows Server 2003

    - by Bill Johnson
    Hi all, Just wondering if someone can assist me further with the set-up of OpenVPN on my Windows Server 2003. I have configured Win Server as per the following guide: http://tinyurl.com/kxusv and I'm now at the stage of Creating the config files. I have a few questions that I need some assistance with. My server IP is 192.168.1.10 and my routers IP address is 192.168.1.1 (the router is a Netgear DGN2000). I have edited the server.ovpn file as per the following: push "dhcp-option DNS X.X.X.X" # Replace the Xs with the IP address of the DNS for your home network (usually your ISP's DNS) push "dhcp-option DNS X.X.X.X" # A second DNS server if you have one to include my ISP DNS and I have not edited anything else. Now my issue is with the client1.opvpn file as per the below: client dev tap #dev-node MyTAP #If you renamed your TAP interface or have more than one TAP interface then remove the # at the beginning and change "MyTAP" to its name proto udp remote YOURHOST.dyndns.org 1194 #You will need to enter you dyndns account or static IP address here. The number following it is the port you set in the server's config route 192.168.1.0 255.255.255.0 vpn_gateway 3 #This it the IP address scheme and subnet of your normal network your server is on. Your router would usually be 192.168.1.1 resolv-retry infinite nobind persist-key persist-tun ca "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ca.crt" cert "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\client1.crt" # Change the next two lines to match the files in the keys directory. This should be be different for each client. key "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\client1.key" # This file should be kept secret ns-cert-type server cipher BF-CBC # Blowfish (default) encrytion comp-lzo verb 1 To me it looks like I will need to amend the following: remote YOURHOST.dyndns.org 1194 #You will need to enter you dyndns account or static IP address here. The number following it is the port you set in the server's config route 192.168.1.0 255.255.255.0 vpn_gateway 3 #This it the IP address scheme and subnet of your normal network your server is on. Your router would usually be 192.168.1.1 So, should the first line be the static IP of the machine that I'm applying this to? The IP address of the server (192.168.1.10) or something else? I'm also stuck on the second part 'route 192.168.1.0 255.255.255.0 vpn_gateway 3' Should this be the router IP which is 192.168.1.1 and the subnet is 255.255.255.0 and that is all I need to alter? The final part that I'm stuggling with is Configuring the router. Basically I have a Netgear DGN2000 and as it mentions that the router should be configured to port forward port 1194 to the server’s IP address of 192.168.1.150 all I have been able to do is in 'Firewall Rules' and on 'Inbound Services', set the Service to 'Any(ALL) and Send to LAN Server point to 1923.168.1.150. I'm not sure if this is correct? It is the following stage of the help guide that I'm struggling with and really need some help with: You need to make sure the port you configured OpenVPN to listen on is forwarded on the router to the IP address of your server. On the WRT54G, port forwarding is configured in the “Applications & Gaming” section. Enter 1194 for the port, UDP for the protocol, and 192.168.1.150 for the IP address. Make sure the entry is enabled and then save the setting. Next, you need to add an entry to the router’s Routing Table. This will enable the router to properly route requests from the clients to the TAP interface of the server. On the WRT54G you would go to the “Setup” page and then the “Advanced Routing” section. Enter the follwing info to make the entry: Enter Route Name: openVPN Destination LAN IP: 192.168.10.0 Subnet Mask: 255.255.255.252 Default Gateway: 192.168.1.150 Interface: LAN & Wireless Once the info has been typed in make sure you save the setting. Can anyone possibly guide me through setting this part up with my Netgear router. I see that once I have these 2 parts complete I'm there so I would really appreciate someone walking me through what is required in completing this. Much appreciated.

  • Listening for TCP and UDP requests on the same port

    - by user339328
    I am writing a Client/Server set of programs Depending on the operation requested by the client, I use make TCP or UDP request. Implementing the client side is straight-forward, since I can easily open connection with any protocol and send the request to the server-side. On the servers-side, on the other hand, I would like to listen both for UDP and TCP connections on the same port. Moreover, I like the the server to open new thread for each connection request. I have adopted the approach explained in: link text I have extended this code sample by creating new threads for each TCP/UDP request. This works correctly if I use TCP only, but it fails when I attempt to make UDP bindings. Please give me any suggestion how can I correct this. tnx Here is the Server Code: public class Server { public static void main(String args[]) { try { int port = 4444; if (args.length > 0) port = Integer.parseInt(args[0]); SocketAddress localport = new InetSocketAddress(port); // Create and bind a tcp channel to listen for connections on. ServerSocketChannel tcpserver = ServerSocketChannel.open(); tcpserver.socket().bind(localport); // Also create and bind a DatagramChannel to listen on. DatagramChannel udpserver = DatagramChannel.open(); udpserver.socket().bind(localport); // Specify non-blocking mode for both channels, since our // Selector object will be doing the blocking for us. tcpserver.configureBlocking(false); udpserver.configureBlocking(false); // The Selector object is what allows us to block while waiting // for activity on either of the two channels. Selector selector = Selector.open(); tcpserver.register(selector, SelectionKey.OP_ACCEPT); udpserver.register(selector, SelectionKey.OP_READ); System.out.println("Server Sterted on port: " + port + "!"); //Load Map Utils.LoadMap("mapa"); System.out.println("Server map ... LOADED!"); // Now loop forever, processing client connections while(true) { try { selector.select(); Set<SelectionKey> keys = selector.selectedKeys(); // Iterate through the Set of keys. for (Iterator<SelectionKey> i = keys.iterator(); i.hasNext();) { SelectionKey key = i.next(); i.remove(); Channel c = key.channel(); if (key.isAcceptable() && c == tcpserver) { new TCPThread(tcpserver.accept().socket()).start(); } else if (key.isReadable() && c == udpserver) { new UDPThread(udpserver.socket()).start(); } } } catch (Exception e) { e.printStackTrace(); } } } catch (Exception e) { e.printStackTrace(); System.err.println(e); System.exit(1); } } } The UDPThread code: public class UDPThread extends Thread { private DatagramSocket socket = null; public UDPThread(DatagramSocket socket) { super("UDPThread"); this.socket = socket; } @Override public void run() { byte[] buffer = new byte[2048]; try { DatagramPacket packet = new DatagramPacket(buffer, buffer.length); socket.receive(packet); String inputLine = new String(buffer); String outputLine = Utils.processCommand(inputLine.trim()); DatagramPacket reply = new DatagramPacket(outputLine.getBytes(), outputLine.getBytes().length, packet.getAddress(), packet.getPort()); socket.send(reply); } catch (IOException e) { e.printStackTrace(); } socket.close(); } } I receive: Exception in thread "UDPThread" java.nio.channels.IllegalBlockingModeException at sun.nio.ch.DatagramSocketAdaptor.receive(Unknown Source) at server.UDPThread.run(UDPThread.java:25) 10x

Outpost has gateway_enable="YES" in its rc.conf which correctly sets net.inet.ip.forwarding to 1 as mentioned earlier. As far as I know, that's all that's required to make a FreeBSD box forward packets between interfaces. Is there something else I could be forgetting ? FWIW, pinging 10.0.1.253 from Kino has the same result - the traffic does not get forwarded. UPDATE: I've found that I can only ping certain IP's on Guchuko's LAN from Outpost. From Outpost I can ping 192.168.0.3 and 192.168.0.2, but 192.168.99 and 192.168.0.4 are unreachable. The same tcpdump behavior can be seen. I think this means the problem can't be due to ipforwarding or routing, because Outpost can reach SOME hosts on Guchuko's LAN but not others and likewise, Guchuko can reach two hosts on Outpost's LAN, but not others. This baffles me.

  • jQuery $.ajax response empty, but only in Chrome

    - by roguepixel
    I've exhausted every avenue of research to solve this one so hopefully someone else will think of something I just didn't. Relatively straight forward setup, I have a html page with some javascript that makes an ajax request to a URL (in the same domain) the java web app in the background does its stuff and returns a partial html page (no html, head or body tags, just the content) which should be inserted at a particular point in the page. All sounds pretty easy and the code I have works in IE, Firefox and Safari, but not in Chrome. In Chrome the target element just ends up empty and if I look at the resource request in Chromes developer tools the response content is also empty. All very confusing, I've tried a myriad of things to solve it and I'm just out of ideas. Any help would be greatly appreciated. var container = $('#container'); $.ajax({ type: 'GET', url: '/path/to/local/url', data: data('parameters=value&another=value2'), dataType: 'html', cache: false, beforeSend: requestBefore, complete: requestComplete, success: requestSuccess, error: requestError }); function data(parameters) { var dictionary = {}; var pairs = parameters.split('&'); for (var i = 0; i < pairs.length; i++) { var keyValuePair = pairs[i].split('='); dictionary[keyValuePair[0]] = keyValuePair[1]; } return dictionary; } function requestBefore() { container.find('.message.error').hide(); container.prepend('<div class="modal"><div class="indicator">Loading...</div></div>'); } function requestComplete() { container.find('.modal').remove(); } function requestSuccess(response) { container.empty(); container.html(response); } function requestError(response) { if (response.status == 200 && response.responseText == 'OK') { requestSuccess(response); } else { container.find('.message.error').fadeIn('slow'); } } All of this is executed in a $(document).ready(function() {}); Cheers, Jim @Oleg - Additional information requested, an example of the response that the ajax call might receive. <p class="message error hidden">An unknown error occured while trying to retrieve data, please try again shortly.</p> <div class="timeline"> <a class="icon shuttle-previous" rel="max_id=16470650733&page=1&q=something">Newer Data</a> <a class="icon shuttle-next" rel="max_id=16470650733&page=3&q=something">Older Data</a> </div> <ol class="social"> <li class="even"> <div class="avatar"> <img src="sphere_normal.gif"/> </div> <p> Some Content<br/> <span class="published">Jun 18, 2010 11:29:05 AM</span> - <a target="_blank" href="">Direct Link</a> </p> </li> <li class="odd"> <div class="avatar"> <img src="sphere_normal.gif"/> </div> <p> Some Content<br/> <span class="published">Jun 18, 2010 11:29:05 AM</span> - <a target="_blank" href="">Direct Link</a> </p> </li> </ol> <div class="timeline"> <a class="icon shuttle-previous" rel="max_id=16470650733&page=1&q=something">Newer Data</a> <a class="icon shuttle-next" rel="max_id=16470650733&page=3&q=something">Older Data</a> </div>

  • trie reg exp parse step over char and continue

    - by forest.peterson
    Setup: 1) a string trie database formed from linked nodes and a vector array linking to the next node terminating in a leaf, 2) a recursive regular expression function that if A) char '*' continues down all paths until string length limit is reached, then continues down remaining string paths if valid, and B) char '?' continues down all paths for 1 char and then continues down remaining string paths if valid. 3) after reg expression the candidate strings are measured for edit distance against the 'try' string. Problem: the reg expression works fine for adding chars or swapping ? for a char but if the remaining string has an error then there is not a valid path to a terminating leaf; making the matching function redundant. I tried adding a 'step-over' ? char if the end of the node vector was reached and then followed every path of that node - allowing this step-over only once; resulted in a memory exception; I cannot find logically why it is accessing the vector out of range - bactracking? Questions: 1) how can the regular expression step over an invalid char and continue with the path? 2) why is swapping the 'sticking' char for '?' resulting in an overflow? Function: void Ontology::matchRegExpHelper(nodeT *w, string inWild, Set<string> &matchSet, string out, int level, int pos, int stepover) { if (inWild=="") { matchSet.add(out); } else { if (w->alpha.size() == pos) { int testLength = out.length() + inWild.length(); if (stepover == 0 && matchSet.size() == 0 && out.length() > 8 && testLength == tokenLength) {//candidate generator inWild[0] = '?'; matchRegExpHelper(w, inWild, matchSet, out, level, 0, stepover+1); } else return; //giveup on this path } if (inWild[0] == '?' || (inWild[0] == '*' && (out.length() + inWild.length() ) == level ) ) { //wild matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover);//follow path -> if ontology is full, treat '*' like a '?' } else if (inWild[0] == '*') matchRegExpHelper(w->alpha[pos].next, '*'+inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //keep adding chars if (inWild[0] == w->alpha[pos].letter) //follow self matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //follow char matchRegExpHelper(w, inWild, matchSet, out, level, pos+1, stepover);//check next path } } Error Message: +str "Attempt to access index 1 in a vector of size 1." std::basic_string<char,std::char_traits<char>,std::allocator<char> > +err {msg="Attempt to access index 1 in a vector of size 1." } ErrorException Note: this function works fine for hundreds of test strings with '*' wilds if the extra stepover gate is not used Semi-Solved: I place a pos < w->alpha.size() condition on each path that calls w->alpha[pos]... - this prevented the backtrack calls from attempting to access the vector with an out of bounds index value. Still have other issues to work out - it loops infinitely adding the ? and backtracking to remove it, then repeat. But, moving forward now. Revised question: why during backtracking is the position index accumulating and/or not deincrementing - so at somepoint it calls w->alpha[pos]... with an invalid position that is either remaining from the next node or somehow incremented pos+1 when passing upward?

  • Received memory warning on setimage

    - by Sam Budda
    This problem has completely stumped me. This is for iOS 5.0 with Xcode 4.2 What's going on is that in my app I let user select images from their photo album and I save those images to apps document directory. Pretty straight forward. What I do then is that in one of the viewController.m files I create multiple UIImageViews and I then set the image for the image view from one of the picture that user selected from apps dir. The problem is that after a certain number of UIImage sets I receive a "Received memory warning". It usually happens when there are 10 pictures. If lets say user selected 11 pictures then the app crashes with Error (GBC). NOTE: each of these images are at least 2.5 MB a piece. After hours of testing I finally narrowed down the problem to this line of code [button1AImgVw setImage:image]; If I comment out that code. All compiles fine and no memory errors happen. But if I don't comment out that code I receive memory errors and eventually a crash. Also note it does process the whole CreateViews IBAction but still crashes at the end. I cannot do release or dealloc since I am running this on iOS 5.0 with Xcode 4.2 Here is the code that I used. Can anyone tell me what did I do wrong? - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. [self CreateViews]; } -(IBAction) CreateViews { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask ,YES); documentsPath = [paths objectAtIndex:0]; //here 15 is for testing purposes for (int i = 0; i < 15; i++) { //Lets not get bogged down here. The problem is not here UIImageView *button1AImgVw = [[UIImageView alloc] initWithFrame:CGRectMake(10*i, 10, 10, 10)]; [self.view addSubview:button1AImgVw]; NSMutableString *picStr1a = [[NSMutableString alloc] init]; NSString *dataFile1a = [[NSString alloc] init]; picStr1a = [NSMutableString stringWithFormat:@"%d.jpg", i]; dataFile1a = [documentsPath stringByAppendingPathComponent:picStr1a]; NSData *potraitImgData1a =[[NSData alloc] initWithContentsOfFile:dataFile1a]; UIImage *image = [[UIImage alloc] initWithData:potraitImgData1a]; // This is causing my app to crash if I load more than 10 images! //[button1AImgVw setImage:image]; } NSLog(@"It went to END!"); } //Error I get when 10 images are selected. App does launch and work 2012-10-07 17:12:51.483 ABC-APP[7548:707] It went to END! 2012-10-07 17:12:51.483 ABC-APP [7531:707] Received memory warning. //App crashes with this error when there are 11 images 2012-10-07 17:30:26.339 ABC-APP[7548:707] It went to END!
