  • Human vs human android chess game design

    - by Plejo
    First of all I am total amateur in game development and sorry for my poor English. I want to make android human vs human chess game. So I am wondering how to design it? scenario 1: User connect to server, find opponent and send moves to server using socket, so match is running on a server side. I think this is not good idea because move should be validated on client side - or do I have to validate moves on client side? I do not think this is good solution because game is seperated. scenario 2: Using hole punching technique so server is needed only for connection between players, so game is running on android devices. which approach do you suggest? Or is there any better solution? Which server is best to use?

  • Handy SQL Server Functions Series (HSSFS) Part 2.0 - Prelude to Parsing Patterns Properly

    - by Most Valuable Yak (Rob Volk)
    In Part 1 of the series I wrote about 2 lesser-known and somewhat undocumented functions. In this part, I'm going to cover some familiar string functions like Substring(), Parsename(), Patindex(), and Charindex() and delve into their strengths and weaknesses. I'm also splitting this part up into sub-parts to help focus on a particular technique and/or problem with the technique, hence the Part 2.0. Consider this a composite post, or com-post, if you will. (It may just turn out to be a pile of sh_t after all) I'll be using a contrived example, perhaps the most frustratingly useful, or usefully frustrating, function in SQL Server: @@VERSION. Contrived, because there are better ways to get the information (which I'll cover later); frustrating, because of the way Microsoft formatted the value; and useful because it does have 1 or 2 bits of information not found elsewhere. First let's take a look at the output of @@VERSION: Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (Intel X86) Apr 2 2010 15:53:02 Copyright (c) Microsoft Corporation Developer Edition on Windows NT 5.1 <X86> (Build 2600: Service Pack 3) There are 4 lines, with lines 2-4 indented with a tab character.  In case your browser (or this blog software) doesn't show it correctly, I gave each line a different color.  While this PRINTs nicely, if you SELECT @@VERSION in grid mode it all runs together because it ignores carriage return/line feed (CR/LF) characters.  Not fatal, but annoying. Note that @@VERSION's output will vary depending on edition and version of SQL Server, and also the OS it's installed on.  Despite the differences, the output is laid out the same way and the relevant pieces are in the same order. I'll be using the following view for Parts 2.1 onward, so we have a nice collection of @@VERSION information: create view version(SQLVersion,VersionString) AS ( select 2000, 'Microsoft SQL Server 2000 - 8.00.2055 (Intel X86) Dec 16 2008 19:46:53 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 3)' union all select 2005, 'Microsoft SQL Server 2005 - 9.00.4053.00 (Intel X86) May 26 2009 14:24:20 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 3)' union all select 2008, 'Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (Intel X86) Apr 2 2010 15:53:02 Copyright (c) Microsoft Corporation Developer Edition on Windows NT 5.1 <X86> (Build 2600: Service Pack 3)' union all select 2005, 'Microsoft SQL Server 2005 - 9.00.3080.00 (Intel X86) Sep 6 2009 01:43:32 Copyright (c) 1988-2005 Microsoft Corporation Standard Edition on Windows NT 5.2 (Build 3790: Service Pack 2)' union all select 2008, 'Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (Hypervisor)' union all select 2008, 'Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Express Edition with Advanced Services (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (Hypervisor)' ) Feel free to add your own @@VERSION info if it's not already there. In Part 2.1 I'll focus on extracting the SQL Server version number (10.50.1600.1 in first example) and the Edition (Developer), but will have a solution that works with all versions.  Stay tuned!

    - by Muhammad Gelbana
    I downloaded MySQL's installation package and ran the following command after installing a fresh Ubuntu server. dpkg -i mysql-5.5.28-debian6.0-x86_64.deb It installed fine and then I tried starting up the server manually /opt/mysql/server-5.5/bin/mysqld And the following error came up /opt/mysql/server-5.5/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory How can I install that library in an offline way ? I have no means whatsoever to an internet connection from that server and I can't even relocate it to have internet connection temporarily ! Thank you.

  • Forward TCP Connections with Iptables

    - by opc0de
    I receive connections to my server from several ip addresses I want to route these connections just like rinetd does but based on the ip the connection is coming from to connect to a specified host. Just like this: IP 10.10.12.1 => CONNECTS TO MY SERVER => MY SERVER REDIRECTS IT TO 82.12.12.1 IP 10.10.12.2 => CONNECTS TO MY SERVER => MY SERVER REDIRECTS IT TO 81.121.12.10 etc Is it possible or do I need to write my own daemon to achieve this functionality ?

  • DHCP won't start / subnetting

    - by user114371
    I recently changed the IP address on an Ubuntu 12.04 server I have in my lab, which is running isc-dhcp-server. After doing so and modifying the dhcpd.conf file, my dhcp service would not start. I basically used the same configuration, except I modified everything to use /25 scopes rather than /24. When I try to start / restart the service, I see the following: MY@ubuntuserver:~$ sudo service isc-dhcp-server restart stop: Unknown instance: isc-dhcp-server start/running, process 20918 It looks like it starts, but it isn't actually running and Webmin states that the DHCP service is not running. So my question is, does isc-dhcp-server support subnetting (CIDR) style scopes, or must they be class A / B / C scopes (doesn't seem likely)? I've double checked the interface reference (this is a VM with only one defined eth0 interface) and everything else I can thing of.

  • MySQL Server 5.6 default my.cnf and my.ini

    - by user12626240
    We've introduced a default my.cnf / my.ini file for MySQL Server that you can now see in the 5.6.8 release candidate: # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M   # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin   # These are commonly set, remove the # and set as required. # basedir = ..... # datadir = ..... # port = ..... # socket = ..... # server_id = .....   # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M   sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES    There is also a template file called my-default.cnf or my-default.ini that has these lines near the start: # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.   On Linux systems, the mysql_install_db command will copy the template file to the final location, where the server will read and use the file, removing the extra three lines. On Windows, the installer will create extra settings based on the answers you gave during installation. Neither will overwrite an existing my.cnf or my.ini file. The only initially active setting here is to change the value of  sql_mode from the server default of NO_ENGINE_SUBSTITUTION to NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES. This strict mode changes warnings for some non-standard behaviour into errors. This can cause applications which rely on the non-standard things, like dates that aren't valid, to lose data. If we had just changed the server default, the new setting would affect all servers that lack an explicit sql_mode setting, including those where strict mode is harmful. So we did it in the default file instead because that will only affect new server installations. You should expect that in our next version after 5.6, the server default will include STRICT_TRANS_TABLES. Our Windows installer and some of our connectors already use STRICT_TRANS_TABLES by default. Strict has been our preferred setting for many years and it is good to see some development platforms are using it. If you need the old behaviour, just remove the STRICT_TRANS_TABLES setting. If you do this, please also ask your application provider to make it unnecessary. They can do that by setting the session sql_mode setting in their own connections, so the rest of the applications using the server don't have to have an undesirable default. We've kept this file as small as possible because we found that our old files were too big and confused people. We've also now removed the old my-huge and related example files. One key part of this is the link to the documentation, where we will provide an introduction to some key settings. We'd like to hear your feedback on settings that will benefit most users or are most important to call out for existing users. Please do that by commenting here or if you prefer by adding comments to this bug report.

  • Timer_EntityBody, Timer_ConnectionIdle and Connection Closed Unexpectly

    - by ihsany
    We have a windows application, it connects to a web service (XML web service hosted on a Windows 2008 Server IIS 7.5, no antivirus) and fetches some data to the client. But sometimes (around 5%-10% of the requests), it gives an error when trying to connect web service.

  • UNC Path fails by IP "no network provider accepted the given network path", but works using hostname

    - by BoyMars
    I have an unusual problem with a Windows Server 2003 (Standard x86) box. It appears the machine will not accept connections to its shares (locally and from other domain member servers) by using its ip address in a UNC path. The error returned is: "no network provider accepted the given network path" This is the case with the machine's ip address: \\10.0.8.x and even the loopback address: \\127.0.0.1 \\localhost does not work... but using the hostname (fqdn or not) works: \\server & \\server.domain.local The local windows firewall for this server is off, ping/rdp/other services respond fine using the IP address. The following services are running and have been restarted: Computer Browser Workstation Server The server itself has been rebooted too. Event 8032 in the system log indicates that: The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{29A6A925-AFB3-47E2-BA59-DDA086DEAE7A}. The backup browser is stopping. The domain controller has not been restarted, no other servers have experienced this problem, yet there are a number of browser (8021) related errors in the logs on this server. Does anyone have any suggestions? I would like to avoid rejoining this server to the domain if possible.

  • STUN-server using AWS

    - by Yrlec
    We are about to hire some consultants to help us set up an AWS-based server environment that will enable us to handle NAT Traversal for our P2P application. One important part of the NAT Traversal infrastructure is the STUN-server (http://en.wikipedia.org/wiki/STUN). They just told us that in order for the STUN-server to work you must have two public static IP-addresses pointing to the same server. To more specific they said this: It appears that you need 2 static IPs for each server for the STUN to work. Please note, these IPs have to be put into the configuration file, therefore, each time you restart the instance you have to make sure you either use the same IPs or you have to update configuration. As you plan to use AWS for your installation, please confirm that you can have 2 static IP for each server. Our question is if this is possible using AWS and if so, how? If not, do you know any other way to set up a STUN-server using AWS?

  • How do I set up a public server on a network?

    I am trying to set up a personal cloud server with OwnCloud on Ubuntu. LAMP is all set up. I was able to access it using the external IP address when I connected it directly to the modem, but what if I what if I want my server to share a LAN? I still want it accessible over the internet, but then if I go to the IP address from a web browser, it just tries to log into to router admin tools. The internal IP address works across the LAN, but I want to be able to access it from anywhere. This may be simple and I may be over-thinking it, but how do access my server? The router I am using is ASUS WL-520GU.

  • MySQL is hogging my server resources

    - by Reacen
    Does anyone have any idea of what can cause this weird behaviour and how I go about fixing it? This is all coming from MySQL only (both RAM and CPU usage), for about 10 minutes after I reboot my Java game server (that has a pool of 256 connections). There are not that many queries and I think it may be more of a MySQL misconfiguration problem. My server: 3.20 GHz * 6 core / 24 GB RAM / 64 bit Windows Server 2003. My game server: Java server, with 256 MySQL connections pool (MyISAM engine), about 500,000 accounts, and 9 million rows of game items in database and about 3,000 players are connected. After about 15 minutes of the game server reboot, the server resumes its stability and CPU usage drop down to 1% ~ 5% and memory to 6 GB. Here is a copy of my MySQL configuration. Also, any advice about my MySQL configuration will be appreciated. I really set it up almost at random. # Example MySQL config file for very large systems. # # This is for a large system with memory of 1G-2G where the system runs mainly # MySQL. # # You can copy this file to # /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options (in this # installation this directory is C:\mysql\data) or # ~/.my.cnf to set user-specific options. # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] #log=c:\mysql.log port = 3306 socket = /tmp/mysql.sock skip-locking key_buffer_size = 2572M max_allowed_packet = 64M table_open_cache = 512 sort_buffer_size = 128M read_buffer_size = 128M read_rnd_buffer_size = 128M myisam_sort_buffer_size = 500M thread_cache_size = 32 query_cache_size = 1948M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 12 max_connections = 5000 # Don't listen on a TCP/IP port at all.

  • Latency between IIS and SQL on same physical, two VMs

    - by Jerad Rose
    I have a single server (2x4 core CPUs, 32GB ram), that is a Windows Server 2012 Hyper V host, and it hosts two guest VMs (also Windows Server 2012 instances). One of them is a web server, the other is a SQL server. When hitting a page that loops over 50 records, there is noticeable latency. I capture/report the timings of each iteration on the loop, and each iteration is about 20-30 milliseconds. Of course, this amounts to over a second of latency for the whole loop. I thought maybe SQL needed to be tuned, but running profiler on it, the queries are showing almost 0 duration, so it seems the bottleneck is in transit between the two VMs. I have both VMs configured to use the actual NIC (vs. using a VNIC), so maybe that's part of my problem. Also, this is a classic ASP site, so it's using the SQL OLE DB provider, and I'm wondering if that is part of the problem. This is a new server setup, from an existing Windows 2003/IIS6 server setup where both web and DB run on the same server instance (no virtualization). On that setup, there is no such latency when looping over the cursor like this. But there are so many variables, I'm not sure where to start ruling things out.

  • How does a company proxy server act in reporting internet usage of employees?

    - by Mehper C. Palavuzlar
    Our company recently set up a proxy server. As far as I understand, they want to apply some access policies to undesired sites, and log/audit the usage of the internet and generate employee internet usage reports. My question is related to the latter part. Before they were using a proxy server, they were also generating internet usage reports. At that point, what kind of contribution will the new proxy server make? Does it have further advantages on reporting internet usage?

  • ESXi 4.0 Guests Locking up

    - by Brendan Sherwin
    I installed ESXi 4.0 on an HP Proliant g5 with a 64bit Xeon processor and took advantage of the free license as I work for a public school. I created two instances of server 2003 from scratch, one to be the DC, DHCP, the other to be a file server and DNS/DHCP backup. I had both guests up and running fine, setup my user accounts, transferred the data, etc etc. Once I joined a client machine to the domain, I would find that both of my Windows guests would lock up. Sometimes it would be for five or so minutes, once it was overnight. The "locked up" state means that as far I could tell, all services were stopped; dhcp no longer handed out IP's, DNS stopped working, I couldn't RDP into the server. The ESXi host, my HP server, was still running fine. VSphere was working, and I could look at the performance of the individual guests.I would try Powering off the hosts from inside VSPhere, and the hosts would start powering off, but get stuck at 95%, and stay that way, sometimes only for 10 minutes, others for hours. Several times I had to restart ESXi from it's console in order to restart my machines. Now, can anyone tell me what is happening, and how I can fix it, or take steps to prevent it? I hired a consultant to come take a look at it, someone who's experience and knowledge I trust, and he told me he had never seen anything like this ever before. He spoke to a friend of his who is VM certified, and he also said he had never heard of this issue. Thanks for your replies, and I'll do my best to respond ASAP. Currently, the server is powered off, and I've reinstituted my nine year old Server 2000 boxes, and I'm considering installing ESXi 3.5. Does anyone know a host created in 4.0 will work in 3.5? I'd really like to avoid having to rebuild those accounts! I know 4.0 works on this server, as I have another server in another school with the same exact hardware running 4.0 fine. Brendan

  • how connect to local mysql server (LAN)

    - by clarkk
    I got two Debian 6 servers - one for web and one for the database.. How can I connect through the local area network? On both servers I have permanently changed the hostnames /etc/hostname /etc/hosts web => web-server db => db-server In the privileges in mysql I have set the root user to accept requests from web-server (instead of localhost) and from the web-server I connect to db-server in my.cnf I have escaped the following line: # bind-address = 127.0.0.1 error Warning: mysqli::mysqli(): (HY000/2005): Unknown MySQL server host 'db-server' (1)

  • Automatic allocation(not Dynamic Allocation) on Windows DHCP server

    - by Kazoom
    DHCP supports three different mechanisms for IP address allocation: Manual allocation: the server's administrator creates a configuration for the server that includes the MAC address and IP address of each DHCP client that will be able to get an address: functionally equivalent to BOOTP though the protocol is incompatible. Automatic allocation: the server's administrator creates a configuration for the server that includes only IP addresses, which it gives out to clients. An IP address, once associated with a MAC address, is permanently associated with it until the server's administrator intervenes. Dynamic allocation: like automatic allocation except that the server will track leases and give IP addresses whose lease has expired to other DHCP clients How can i configure the automatic allocation on Windows 2000 or XP DHCP server? i can think of setting the lease to unlimited period, but i m not sure if the computer shutsdown gracefully it will make the ip address available to other machine.

  • How can I remotely tell what brand/model internal SCSI card is installed in a machine?

    - by edmicman
    I am doing some consulting work for a previous employer upgrading and migrating old servers to new hardware. There is an existing file server (HP ProLiant DL380) that has an tape backup drive connected; it is using a SCSI interface and I'm pretty sure it's using an internal SCSI card. They are upgrading to a new server hardware (HP ProLiant DL160 G6). The old server is 2U, the new one 1U and we would want to move the tape drive to the new server, too. I'm trying to figure out if the SCSI card in the old server would be able to be installed in the new one or if we'll need to source a new card; mostly I don't know for sure the height of the card and if it's low-profile enough that it would fit in the new server. There is not much of a technical resource onsite and the old server is in-use anyway so I would like to avoid making a trip in myself or trying to have someone onsite pop open the case and tell me what card is there. It's running Windows Server 2003 - is there a way to tell from say Device Manager what make and model the SCSI card might be? Or any other system diagnostic program or something that would give me hardware info like that? Thanks for any info!

  • I'd like to rebuild my web server without web management software; what knowledge, skills, and tools will I require? [closed]

    - by Joe Zeng
    I've been using Webmin for my web server that runs my personal website and a host of other websites for a while now, and I feel like I should be able to manage my web server more directly, because I haven't even touched the Webmin for the past year or so and I feel like maybe it has too much functionality that I have to click through the next time I want to access it or create a new subdomain or database on my site. I want to try something lighter and more wholly manageable, now that I'm more comfortable with using ssh and command-line tools. I've decided that I'm going to try using Django as a framework, but obviously that's only part of the picture. What sort of knowledge will I require?

  • debian mysql server always down

    - by lokheart
    I am hosting a mysql server in a debian 6.0.4 server hosted in linode, the new data is frequently written into the mysql server using R, about 30-40 "write" per minute, about 7 hours a day, 5 days a week. Recently I found that the mysql server seem to down frequently, always give me error that mysql server cannot be connected through socket. I wonder if this is caused by my high demand to my mysql server, and if this can be solved. I am definitely a newbie in manage server. Please let me know if I need to provide additional information for this question in order to get it solved. Thanks.

  • 32bit SQLServer with AWE NOT enabled. Buffer Cache Hit Ratio High, Disk Read Queue VERY HIGH, WHY?

    - by chenwq
    We have a "SQLServer 2005 SP3 32bit Enterprise Edition" running on a 32 bit Windows 2003 32bit Enterprise Edition 12GB RAM with AWE enabled using RAID5(5 pysical disks). We tuned AWE to enabled and restart sqlserver this afternoon after work, hope the performance will be better than old time. But there is something that we are very confused. On working days, SQLServer has a very bad performance. When we are looking for reasons, we check Windows Performance counter. Avg. Disk Read Queue Lenght > 140 Avg. Disk Write Queue Length < 1 SQL Server Buffer Cache Hit Ratio > 96% %Processor Time < 30% SQL Server Total Server Memory < 1.8G Obviously, without AWE enabled, SQL Server can use only less than 2G memory. My Question is: why "SQL Server Total server Memory" is less than 2G?I think SQL Server will use all 2G process address space. Does this counter count anything out? we known that sql server is sufferring lack of memory, but why "buffer hit ratio“ is as high as 96? Any advice is welcomed!

  • OpenVPN server behind firewall issues

    - by Gabriel
    I'm trying to setup an OpenVPN but I do have some problems doing it. This is my scenario: INTERNET --- HOME ROUTER (10.1.0.0/28) --- FIREWALL SERVER (DEFAULT GATEWAY FOR MY INTERNAL LAN 10.1.0.2) --- OpenVPN Server (10.1.0.9 LAN | 10.2.0.1 VPN) single nic / bridge iface I can connect to my VPN server successfully (it gets the 10.2.0.5 address). Though, I'm not able to ping anything, neither my VPN server, nor my lan clients. I guess the problem is on the firewall. I'm not really an expert on iptables, I tried adding plenty of different rules without success. I would appreciate a lot if someone could explain me how to get to work the VPN server in this scenario. After connecting through VPN, when I try to ping the server, I'm not really sure about how the ping message gets to the server and how the response should go back to the client. Thanks a lot Gabriel
