  • Squid 2.7.6 not honoring ACL rules

    - by peppery
    Hello there, I have a /24 block of IP addresses assigned to a single server that I have been attempting to install Squid on an Ubuntu server machine. All of the IP addresses are set up correctly (aliases of eth0) in /etc/networking and work as they should be, using cURL I can specify an interface and it goes out on the correct address as it should be. I would like Squid to take the incoming IP address the request was sourced to and proxy the request out on the same IP (e.g incoming 123.123.123.1:3128 - 123.123.123.1, .2 - .2, etc) and have set up these ACL rules in /etc/squid.conf acl ip1 myip x.x.x.1 tcp_outgoing_address x.x.x.1 ip1 acl ip2 myip x.x.x.2 tcp_outgoing_address x.x.x.2 ip2 acl ip3 myip x.x.x.3 tcp_outgoing_address x.x.x.3 ip3 and so on, as this seems to be the only way to do what I want (from research). However, after much frustration, Squid seems to be ignoring these rules and sending requests out on the default interface. Does anybody have any suggestions? Thanks.

  • i7 4770k or i7 4930k - Which for faster compile times? [on hold]

    - by Chumm
    I've looked up comparisons and found that single core performance seems to be better on i7 4770k, but has less cores that the i7 4930k. Would VS take advantage of extra cores when compiling, or would the difference be negible. I'm looking to buy the PC primarily for programming, so which would be better for visual studio? I already have the rest of my build ready, I just need to decide on this! :) thanks

  • Remote connect to mysql server?

    - by LF4
    I've been trying to figure out why I keep getting this error when I try to connect to the MySQL server with the following commands. $~ mysql -u username -h SQLserver -p Enter password: ERROR 1045 (28000): Access denied for user 'username'@'myIP' (using password: YES) I've done the following: Port is open in the firewall other wise I wouldn't get the error it'd just timeout.

  • Dedicated server given, how to start?

    - by eduardito
    Hello, I've been given a dedicated server. Unfortunately, I have no idea what to do / how to manage it. I have background in many fields on Computer Science but never got to focus on networking, server management, etc. What I'm asking is for recommended books, Basically, I would like to be able to be proficient and understand well how to manage domain names, zones, setting up mail servers, being able to install easily any web server, and such. Everything needed for proper server management through the shell. I will probably stick with Parallels, or Cpanel for a bit. But I dislike those, especially how it add a lot of intruding user accounts and configs on the file system. Thank you

  • Hyper-V with a single host NIC

    - by Cylindric
    I'm trying to create a simple Hyper-V test machine, and am having more problems than expected with the basic networking. All other hypervisors I've used (vmware server, vmware player, virtualbox) allow me to use the default single NIC in my machine, and then create guests with "bridged" mode so they appear like a normal machine on the network. With the Hyper-V server, when I create a Virtual Switch and set it to "external", I lose all network access from the host. The solutions I've seen online seem to rely on complex configurations requiring multiple vSwitches and RRAS on the host to get it going. Is it really that complex to get a simple, single-NIC Hyper-V server going, in such a way that I can still use the host? The host is Windows 8.

  • What is the point of connecting two routers directly together

    - by rubixibuc
    The way subnets work, wouldn't connecting two router interfaces together require their own subnet between them. Unless that subnet mask has 31 bits, wouldn't that was adress space. I'm asking because I often seen that done in networking books. How can this be done without wasting IP Addresses? They usually draw this when explaining subnetting. They have a central router connected to several other each one supposed to be creating their own subnet. Is this really how subnettimg is done? Example <-------[Router 1]-----Wasteful Subnet-------[Router 2]------> | | | \/

  • Server 2008 Hyper-V User Accounts to access each other

    - by asn1981
    Hi, I have a windows server 2008 r2 with 3 hyper-v vm's IIS server Sql server 3 - Mail server I'm new to networking/server configuration. I have created a Virtual Network and can see each of the 3 VMs as well as the host on the network. I can connect from each VM to the host using the admin account. However, what would be the best (secure) way to create connections/accounts between the VMs, presumabely this shouldn't be done with an admin account but one with lesser priveledges. For example, to be able to access the SQL Server VM from the IIS server VM?

  • ipv6 ssh tunnel service for testing?

    - by Geuis
    I need to do some testing on a service that I run to make sure that it can handle ipv6 addresses. Basically, I need to connect to it from an ipv6 address. I've created a tunnel via tunnelbroker.net, but I'm finding the steps required to get a tunnel configured on my machine and router to be a lot of trouble. Given that I'm not a networking specialist and that I haven't had to dig into routing configuration in years, I'd like to know if there's an existing service that I can just ssh into and use it as my ipv6 endpoint. Simply being able to curl or wget from such an endpoint to my service would be more than enough to test what I need. Thanks!

  • OS won't boot during vs2010 install on vista 64

    - by Noam
    I am installing vs2010 on a vista 64bit machine. During the install it asked for a restart. Since that, vista won't load. I tried restore to previous good config - didn't help. I am only able to boot it using safe mode with networking. When I did that, it continued the vista part of the install (the screen with the 3 out of 3 updates) but after that when I restarted again - still fails. HELP!!!

  • Server's network capabilities are going into some sort of sleep mode?

    - by F4r-20
    I'm having trouble with a server (Windows Server 2008 R2) on my network. It is going down for short periods at a time, but not very often. The interesting thing: If I ping the server from my computer (we'll call this client-x) using the -t switch, I will continuously get no reply. However the second I ping client-x from the server, I can see the previous ping pick up a reply? It's almost as if pinging client-x from the server, wakes up the networking capabilities? Has anybody got any idea what is going on here?

  • what's the safest OS?

    - by Bob
    I have pretty important stuff on my PC (using Windows). All the programming files, passwords etc. And now I thought: Is that even safe to store all this information on a hard drive? What if some virus (or a pseudo-antivirus gets it) M.b. it is better to buy Mac for this purpose? I kinda don't like Linux, cause I hate making million small decisions manually (what drivers to install etc) Will like to hear some opinions.

  • Can I automatically map chrome's bookmarks bar to its jump list?

    - by Alex Nye
    I would like the contents of my bookmarks bar to be present in my Google Chrome jump list, without the manual tedium of managing both the bar's organization and contents and those of the jump list. If it's possible to automatically manage jump lists in such a way as to make this possible, I'd be delighted. I don't think I'm quite ready to attempt programming an extension thus myself. edit: it appears this is not possible. I have submitted the feature as a request to the chrome team.

  • Searching major search engines with text such as <%#

    - by Daniel Dyson
    If I type '<%# vs <%"' into any of the major search engines, everything is stripped out except the 'vs'. I understand why they do this. I would just like to know if anyone knows of a way to escape illegal characters so that they are searched properly. I know this is not strictly a programming question, but it is relevant.

  • What is a proper server for this website

    - by zaidfarekh
    We are using zend framework, doctrine on our website, that will have the minimum of 2000 users daily, please consider that we prefer that the server has opcode caching. And any available technology that speeds up php performance. We have heard that zend server offers an optimal performance for php. Please recommend a hosting server or a vps plan, that can handle such an application. given that our application has some kind of social networking and it applies alot of ajax requests even in minimal usage of the website, for example in 30 min we may have up to 400 requests from an individual user. Thank you in advance

  • Prefer extension methods for encapsulation and reusability?

    - by tzaman
    edit4: wikified, since this seems to have morphed more into a discussion than a specific question. In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. (edit: Even in the current .NET library, I can see places where it would've been useful to have extensions instead of instance methods - for example, all of the utility functions of List<T> (Sort, BinarySearch, FindIndex, etc.) would be incredibly useful if they were lifted up to IList<T> - getting free bonus functionality like that adds a lot more benefit to implementing the interface.) So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself? (edit2: In response to Tomas - while C# did start out with Java's (overly, imo) OO mentality, it seems to be embracing more multi-paradigm programming with every new release; the main thrust of this question is whether using extension methods to drive a style change (towards more generic / functional C#) is useful or worthwhile..) edit3: overridable extension methods The only real problem identified so far with this approach, is that you can't specialize extension methods if you need to. I've been thinking about the issue, and I think I've come up with a solution. Suppose I have an interface MyInterface, which I want to extend - I define my extension methods in a MyExtension static class, and pair it with another interface, call it MyExtensionOverrider. MyExtension methods are defined according to this pattern: public static int MyMethod(this MyInterface obj, int arg, bool attemptCast=true) { if (attemptCast && obj is MyExtensionOverrider) { return ((MyExtensionOverrider)obj).MyMethod(arg); } // regular implementation here } The override interface mirrors all of the methods defined in MyExtension, except without the this or attemptCast parameters: public interface MyExtensionOverrider { int MyMethod(int arg); string MyOtherMethod(); } Now, any class can implement the interface and get the default extension functionality: public class MyClass : MyInterface { ... } Anyone that wants to override it with specific implementations can additionally implement the override interface: public class MySpecializedClass : MyInterface, MyExtensionOverrider { public int MyMethod(int arg) { //specialized implementation for one method } public string MyOtherMethod() { // fallback to default for others MyExtension.MyOtherMethod(this, attemptCast: false); } } And there we go: extension methods provided on an interface, with the option of complete extensibility if needed. Fully general too, the interface itself doesn't need to know about the extension / override, and multiple extension / override pairs can be implemented without interfering with each other. I can see three problems with this approach - It's a little bit fragile - the extension methods and override interface have to be kept synchronized manually. It's a little bit ugly - implementing the override interface involves boilerplate for every function you don't want to specialize. It's a little bit slow - there's an extra bool comparison and cast attempt added to the mainline of every method. Still, all those notwithstanding, I think this is the best we can get until there's language support for interface functions. Thoughts?

  • sendto: Network unreachable

    - by devin
    Hello. I have two machines I'm testing my code on, one works fine, the other I'm having some problems and I don't know why it is. I'm using an object (C++) for the networking part of my project. On the server side, I do this: (error checking removed for clarity) res = getaddrinfo(NULL, port, &hints, &server)) < 0 for(p=server; p!=NULL; p=p->ai_next){ fd = socket(p->ai_family, p->ai_socktype, p->ai_protocol); if(fd<0){ continue; } if(bind(fd, p->ai_addr, p->ai_addrlen)<0){ close(fd); continue; } break; } This all works. I then make an object with this constructor net::net(int fd, struct sockaddr *other, socklen_t *other_len){ int counter; this->fd = fd; if(other != NULL){ this->other.sa_family = other->sa_family; for(counter=0;counter<13;counter++) this->other.sa_data[counter]=other->sa_data[counter]; } else cerr << "Networking error" << endl; this->other_len = *other_len; } void net::gsend(string s){ if(sendto(this->fd, s.c_str(), s.size()+1, 0, &(this->other), this->other_len)<0){ cerr << "Error Sending, " << s << endl; cerr << strerror(errno) << endl; } return; } string net::grecv(){ stringstream ss; string s; char buf[BUFSIZE]; buf[BUFSIZE-1] = '\0'; if(recvfrom(this->fd, buf, BUFSIZE-1, 0, &(this->other), &(this->other_len))<0){ cerr << "Error Recieving\n"; cerr << strerror(errno) << endl; } // convert to c++ string and if there are multiple trailing ';' remove them ss << buf; s=ss.str(); while(s.find(";;", s.size()-2) != string::npos) s.erase(s.size()-1,1); return s; } So my problem is, is that on one machine, everything works fine. On another, everything works fine until I call my server's gsend() function. In which I get a "Error: Network Unreachable." I call gercv() first before calling gsend() too. Can anyone help me? I would really appreciate it.

I think this is not the cause in my case, because my problem occurs after system is up and running. Any idea what is causing this? This is ubuntu server and it should be running and accessed remotely using ssh.

  • Wireless doesn't work on a Lenovo V570

    - by Stephen
    I've had Ubuntu installed on my HD for about 3 months but ever since I ran into this wireless issue I kinda lost my lust of Ubuntu. I have zero experience getting around with/ using the console command. I have a Lenovo V570. I got the driver update for the broadcom networking card via the Additional Drivers application but that did nothing. I love the look and feel of using Ubuntu but I have no technological experience for the matter. Any help would be awesome. When I scan for wireless connections while in Ubuntu, my computer picks up nothing, while on Win7 it will pick up the handful of wireless networks around my area. My wired connection is fine, but the use of not having wireless on a laptop is rather contradictory to it as a feature. Cheers! Also, I just installed 11.10, if that helps any. Yes, I used the search before I posted this, but again I have ZERO understanding of the command stuff and need a meat and potatoes answer(s). stephen@ubuntu:~$ sudo lshw -class network [sudo] password for stephen: *-network UNCLAIMED description: Network controller product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f1900000-f1903fff *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:04:00.0 logical name: eth0 version: 06 serial: f0:de:f1:63:98:14 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl_nic/rtl8168e-2.fw ip=192.168.1.78 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:41 ioport:2000(size=256) memory:f1804000-f1804fff memory:f1800000-f1803fff stephen@ubuntu:~$ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no

  • Mobile Java, shiny and new: Nokia Asha and Nokia SDK 2.0

    - by terrencebarr
    Nokia has announced a series of new S40 phones called “Asha” – mass-market devices with smart-phone features: Good-sized touch screens, 1 GHz processors, WiFi connectivity, social networking integration, and more. Prices starting around €60 retail. In case you don’t know, the S40 series is built on Java ME and has a huge deployed base in many parts of the world where price/performance is critical. Along with the new phones, Nokia is also making available the new Nokia SDK 2.0 for Java (beta), which enables developers to build rich Java applications with multi-touch, sensor support, an improved Maps API, and the Lightweight UI Toolkit (LWUIT) (more API & tools details). Furthermore, there is a host of developer information, the remote device access service, and even a porting guide to help you port your Android app to the new Asha platform. Last, but not least: More and better options to monetize your applications. Nokia has enabled in-app advertising and in-app purchasing, and improved the way applications can be discovered by customers. Nokia has seen downloads from the Nokia app store rise by 63%, now totaling billions. From what I’m hearing, the revenue opportunities on S40 for developers are often way better than what is typical for other smart-phone platforms (where competition is huge and consumers are fickle). Cheers, – Terrence Filed under: Mobile & Embedded Tagged: Asha Series, Java ME, Java ME SDK, Mobile Java, monetization, Nokia, S40

  • Day 2 - Game Design Documentation

    - by dapostolov
    So yesterday I didn't cut any code for my game but I was able to do a tiny bit of research on the XNA Game Development Technology and the communities out there and do you know what? I feel I'm a bit closer to my goal. The bad news is today I didn't cut code either. However, not all is lost because I wanted to get my ideas on paper and today I just did that.  Today, I began to jot down notes about the game and how I felt the visual elements would interact with each other. Unlike my workplace, my personal level of documentation is nothing more than a task list or a mind map of my ideas; it helps me streamline my solutions quiet effectively and circumvent the long process of articulating each thought to the n-th degree. I truly dislike documentation (because I have an extremely hard time articulating my thought and solutions); however, because I tend to do a really good job with documentation I tend to get stuck writing the buggers. But as a generalist remark: 'No Developer likes documentation.' For now let's stick with my basic notes and call this post a living document. Here are my notes, fresh, from after watching the new first episode of Merlin second season! Actually, a quick recommendation to anyone who is reading this (if anyone is): I truly recommend you envelope yourself in the medium or task you're trying to tackle. Be one with moment and feel it! For instance: Are you writing a fantasy script / game? What would the music of the genre sound like? For me the Conan the Barbarian soundtrack by Basil Poledouris is frackin awesome. There are many other good CD's out there, which I listen to (some who even use medival instruments, but Conan I keep returning to. It's a creative trigger for me. Ask yourself what would the imagery look like? Time to surf google for artist renditions of fantasy! What would the game feel like? Start playing some of your favorite games that inspire you, be wary though, have some self control and don't let it absorb your time. Anyhow, onto the documentation... Screens, Scenes, and Sprites. Oh My! (groan...) The first thing that came to mind were the screens, I thought the following would suffice: Menu Screen Character Customisation Screen Loading Screen? Battle Ground The Menu Screen Ok. So, the thought here is when the game loads a huge title is displayed: Wizard Wars. The player is prompted with 3 menu items: 1 Player Game, 2 Player Game, and Exit. Since I'm targetting the PC platform, as a non-networked game to start, I picture myself running my mouse over each menu option and the visual element of the menu item changes, along with a sound to indicate that I am over a curent menu item. And as I move my mouse away, it changes back, and possibly an exit mouse sound. Maybe on the screen somewhere is a brazier alit with a magical tome open right beside it, OR, maybe the tome is the menu! I hear the menu music as mellow, not obtrusive or piercing. On a menu item select, a confirmation sound bellows to indicate the players selection. The Esc key will always return me to the previous screens or desktop. The menu screen must feel...dark, like a really important ritual is about to happen and thus the music should build up. 1 Player Game - > Customize Character(s) 2 Player Game - > Customize Character(s) Exit - > Back to Windows Notes: So the first thing I pick up here are a couple things: First and foremost, my artistic abilities suck crap, so I may have to hire an artist (now that i've said that, lets get techy) graphical objects will be positioned within a scene on each screen / window. Menu items will be represented grapically, possibly animated, and have sound / animation effects triggered by user input or a time line. I have an animated scene involving a brazier or fire on a stick IF I was to move this game to the xbox, I'd have to track which menu item is currently selected (unless I do a mouse pointer type thing.) WindowObject has a scene A Scene has many GameObjects GameObject has a position graphic or animation MenuObject is a GameObject which has a mouse in, mouse out, and click event which either does something graphically (animation), does something with sound, or moves to another screen.  Character Customisation Screen With either the 1 or 2 player option selected, both selections will come to this screen; a wizard requires a name, powers, and vestements of course! Player one will configure his character first and then player two. I considered a split screen for PC but to have two people fighting over a keyboard would probably suck. For XBox, a split screen could work; maybe when I get into the networking portion (phase 2 blog?) of this game I will remove the 2 player option for PC and provide only multiplayer and I will leave 2 player for xbox...hmm... Anyhow...I picture the creation process as follows: Name: (textbox / keyboard entry) - for xbox, this would have to be different. Robe Color: (color box, or something) Stats: Speed, Oomph, and Health. (as sliders) 1 as minimum and 10 as maximum. Ok, Back, and Cancel buttons / options. Each stat has a benefit which are listed below. The idea is the player decides if he wants his wizard to run fast, be a tank and ... hit with a purse.Regardless, the player will have a pool of 12 points to use. Ideally, A balanced wizard will have 5 in each attribute. Spells? The only spell of choice is a ball of fire which comes without question. The music and screen should still feel like a ritual. The Character Speed Basically, how fast your character moves and casts. Oomph (Best Monster Truck Voice): PURE POWAH!!! The damage output of your fireball. Health How much damage you can take. Notes: I realise the game dynamics may sound uninteresting at the moment; but I think after a couple releases, we could have some other grand ideas such as: saved profiles, gold to upgrade arsenal of spells, talents, etc...but for now...a vanilla fireball thrower mage will suffice for this experiment. OK. So... a MenuObject  may need to be loosely coupled to allow future items such as networking? may be a button? a CharacterObject has a name speed oomph health and a funky robe color. cap on the three stats (1-10) an arsenal of 1 spell (possibly could expand this) The Loading Screen As is. The Battleground Screen For now, I'm keeping the screen as max resolution for the PC. The screen isn't going to move or even be a split screen. I'm not aiming high here because I want to see what level of change is involved when new features / concepts are added to game content. I'm interested to find out if we could apply techniques such as MVC or MVVM to this type of development or is it too tightly coupled? This reminds me when when my best friend and I were brainstorming our game idea (this is going back a while...1994, 6?) and he cringed at the thought of bringing business technology into games, especially when I suggested a database to store character information and COM / DCOM as the medium, but it seems I wasn't far off (reflecting); just like his implementation of a xml "config file" for dynamic direct-x menus back before .net in 1999...anyhow...i digress... The Battle One screen, two characters lobing balls of fire at each other...It doesn't get better than that. Every so often a scroll appears...and the fireballs bounce off walls, or the wizard has rapid fire, or even scrolls of healing! The scroll options are endless. Two bars at the top, each the color of the wizard (with their name beside the bar) indicate how much health they have. Possibly the appearance of the scrolls means the battle is taking too long? I'm thinking 1 player controls: up, down, left, right and space to fire the button. Or even possibly, mouse click and shift - mouse button to fire a spell in the direction they are facing. Two player controls: a, s, d, f and space AND arrows (up, down, left, right) and Del key or Crtl. The game ends when a player has 0 health and a dialog box appears asking for a rematch / reconfigure / exit. Health goes down when a fireball (friendly or not), connects with a wizard. When a wizard connects with a scroll, a countdown clock / icon appears near the health bar and the wizard begins to glow. For the most part, a wizard can have only scroll 1 effect on him at a time. Notes: Ok, there's alot to cover here. a CharacterObject is a GameObject it travels at a set velocity it travels in a direction it has sounds (walking, running, casting, impact, dying, laughing, whistling, other?) it has animations (walking, running, casting, impact, dying, laughing, idle, other?) it has a lifespan (determined by health) it is alive or dead it has a position a ScrollObject is a GameObject it carries a transferance of points "damage" (or healing, bad scroll effect?) (determinde by caster) it carries a transferance of "other" it is stationary it has a sound on impact it has a stationary animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by game) it is alive or dead it has a position a WallObject is a GameObject it has a sound on fireball impact? it is a still image / stationary it has an impact animation / or transfers an impact animation it is dead it has a position A FireBall is a GameObject it carries a transferance of poinst "damage" (or healing, bad scroll effect?) (determinde by caster) it travels at a set velocity it travels in a direction it has a sound it has a travel animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by caster) it is alive or dead it has a position As I look at this, I can see some common attributes in each object that I can carry up to the GameObject. I think I'm going to end the documentation here, it's taken me a bit of time to type this all out, tomorrow. I'll load up my IDE and my paint studio to get some good old fashioned cowboy hacking going!   D.
