• MOSS 2007 SP2 - Error while provisioning SSP.

  - by Tim

  This is a brand new installation I am trying to provision the first SSP for MOSS and I keep getting the following error: (Provisioning failed: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.)) The error also keeps appearing in the Application Event Log as event ID 7888. Google searches tell me its a connection between the Sharepoint server and the SQL server however, this is a production SQL Server which has several databases on it that do not experience any problems. These databases also include the Central Admin and Web Application databases for Sharepoint which are all working fine. Any guidance would be greatly appreciated. Thanks in advance.

• Windows 7 Machine Makes Router Drop -All- Wireless Connections

  - by Hammer Bro.

  Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

• Most efficient way to connect an ISAPI Dll to a windows service

  - by Mike Trader

  I am writing a custom server for a client. They want scalability so I must use a thread pool and probably I/O completion port to regulate it. The main requirement is that a windows service manage the HTTP requests for a number of reasons. An example of one would be that a client session spans many requests and continuity must be maintained. Another would be that the ISAPI Dll will be in the IIS address space and so it's code will be lean and very carefully implemented. The extensive processing in the Windows service may get unruly for the duration of the lengthy development. If the service crashes it will not take out IIS. Anyway, the remaining decision is how to have these two processes communicate. We have talked about pipes, tcp, global memory and even a single pipe with multiplexed data ala FastCGI. Would love to hear anyones experience with a decision like this.

• What is wrong with my PHP/MySQL code?

  - by James

  I am building a navigation menu which lists all my categories and subcategories. The problem is it returns only one of these and not all. I have the categories echoed inside the while loop so I'm not sure why it's only showing one result and not all: <?php $query = mysql_query("SELECT * FROM categories_parent"); while ($row = mysql_fetch_assoc($query)) { $id = $row['id']; $name = $row['name']; $slug = $row['slug']; $childStatus = $row['child_status']; // if has child categories if ($childStatus == "1") { echo "<li class='dir'><a href='category.php?slug=$slug'>$name</a>"; echo "<ul id='dropdown'>"; $query = mysql_query("SELECT * FROM categories_child WHERE parent=$id"); while ($row = mysql_fetch_assoc($query)) { $id = $row['id']; $name = $row['name']; $slug = $row['slug']; echo "<li><a href='category.php?slug=$slug'>$name</a></li>"; } echo "</ul>"; echo "</li>"; } // if singular parent else { echo "<li><a href='category.php?slug=$slug'>$name</a></li>"; } } ?> My database tables: -- -- Table structure for table `categories_child` -- CREATE TABLE IF NOT EXISTS `categories_child` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(1000) NOT NULL, `slug` varchar(1000) NOT NULL, `parent` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=139 ; -- -- Dumping data for table `categories_child` -- INSERT INTO `categories_child` (`id`, `name`, `slug`, `parent`) VALUES (138, 'Britney Spears', 'category/celiberties/britney-spears/', 137), (136, 'Tigers', 'category/animals/tigers/', 136), (137, 'Horses', 'category/animals/horses/', 136), (135, 'Lions', 'category/animals/lions/', 136); -- -- Table structure for table `categories_parent` -- CREATE TABLE IF NOT EXISTS `categories_parent` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(1000) NOT NULL, `slug` varchar(1000) NOT NULL, `child_status` int(1) NOT NULL DEFAULT '0', PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=139 ; -- -- Dumping data for table `categories_parent` -- INSERT INTO `categories_parent` (`id`, `name`, `slug`, `child_status`) VALUES (137, 'Celiberties', 'category/celiberties/', 1), (138, 'TV Shows', 'category/tv-shows/', 0), (136, 'Animals', 'category/animals/', 1);

• diagnostic multicast issue using wireshark

  - by Abruzzo Forte e Gentile

  I have a network that is setup for multicast traffic. My setup is the following -Machine A : a server generates multicast traffic. -Machine A : few clients subscribing to that multicast traffic -Machine B : few clients subscribing to that multicast traffic # Address I am using IP : 239.193.0.21 PORT: 20401 The clients in machine A , even if they join the group (I can see IGMP messages through wireshark), don't receive any data while (and this is the funny part) machine B,C and D receive everything. I sorted that issue by completely disabling Linux firewall. Before doing that, I enabled the multicast on the firwall ('reject all'). iptables -A INPUT -m addrtype --src-type MULTICAST -j ACCEPT My question is the following: what I can check in wireshark that can help me in spot such firewall issues in the futures? For TCP/IP I realize by using ping and looking at ICMP packets rejected. What I can check/monitor for multicast? I am using LInux/Red-Hat Enterprise 6.2

• opening socket to google hangs on SYN_SENT

  - by puchu

  I have 2 computers now: downloader (asus at4nm10t-i) with debian and desktop (asus sabertooth 990fx) with gentoo in the same network under NAT even with the same ethernet card: RTL8111E. driver r8169 is compiled as module on both computers. Sometimes in evenings desktop cannot connect to google and all its services like now: curl -v http://www.google.by on downloader it received server's answer immediately. on desktop it hanged and when I ran in other terminal: netstat -ntp | grep curl >>tcp 0 1 192.168.0.7:54126 173.194.35.191:80 SYN_SENT 4876/curl after 1-2 minutes it received server's answer. I was tried to change ip of network, mac address of desktop but nothing changed. When I was trying to connect to another services except google: curl -v http://www.yahoo.com both computers received answers immediately! Only when I rebooted desktop it begins to work with google services correctly I cant understand what is this bug related to. In which bugtracker should I post this: r8169 or linux kernel or google? PS. Desktop was checked with memtest: 5 passes - no errors

• Linux IPTables / routing issue

  - by Jon

  Hi all, EDIT 1/3/10 22:00 GMT - rewrote some of it after further investigation It has been a while since I looked at IPtables and I seem to be worse than before as I can not seem to get my webserver online. Below is my firewall rules on the gateway server that is running the dhcp server accessing the net. The webserver is inside my network on a static IP (192.168.0.98, default port). When I use Nmap or GRC.com I see that port 80 is open on the gateway server but when I browse to it, (via public URL. http://www.houseofhawkins.com) it always fails with a connection error, (nmap cannot connect and figure out what the web server is either). I can nmap the webserver and browse to it just fine via same IP inside my network. I believe it is my IPTable rules that are not letting it through. Internally I can route all my requests. Each machine can browse to the website and traffic works just fine. I can MSTSC / ssh to all the webservers internally and they inturn can connect to the web. IPTABLE: *EDIT - Added new firewall rules 2/3/10 * #!/bin/sh iptables="/sbin/iptables" modprobe="/sbin/modprobe" depmod="/sbin/depmod" EXTIF="eth2" INTIF="eth1" load () { $depmod -a $modprobe ip_tables $modprobe ip_conntrack $modprobe ip_conntrack_ftp $modprobe ip_conntrack_irc $modprobe iptable_nat $modprobe ip_nat_ftp echo "enable forwarding.." echo "1" > /proc/sys/net/ipv4/ip_forward echo "enable dynamic addr" echo "1" > /proc/sys/net/ipv4/ip_dynaddr # start firewall # default policies $iptables -P INPUT DROP $iptables -F INPUT $iptables -P OUTPUT DROP $iptables -F OUTPUT $iptables -P FORWARD DROP $iptables -F FORWARD $iptables -t nat -F #echo " Opening loopback interface for socket based services." $iptables -A INPUT -i lo -j ACCEPT $iptables -A OUTPUT -o lo -j ACCEPT #echo " Allow all connections OUT and only existing and related ones IN" $iptables -A INPUT -i $INTIF -j ACCEPT $iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT $iptables -A OUTPUT -o $EXTIF -j ACCEPT $iptables -A OUTPUT -m state --state ESTABLISHED,RELATED -j ACCEPT $iptables -A FORWARD -i $EXTIF -o $INTIF -m state --state ESTABLISHED,RELATED -j ACCEPT $iptables -A FORWARD -i $INTIF -o $EXTIF -j ACCEPT $iptables -A FORWARD -j LOG --log-level 7 --log-prefix "Dropped by firewall: " $iptables -A INPUT -j LOG --log-level 7 --log-prefix "Dropped by firewall: " $iptables -A OUTPUT -j LOG --log-level 7 --log-prefix "Dropped by firewall: " #echo " Enabling SNAT (MASQUERADE) functionality on $EXTIF" $iptables -t nat -A POSTROUTING -o $EXTIF -j MASQUERADE $iptables -A INPUT -i $INTIF -j ACCEPT $iptables -A OUTPUT -o $INTIF -j ACCEPT #echo " Allowing packets with ICMP data (i.e. ping)." $iptables -A INPUT -p icmp -j ACCEPT $iptables -A OUTPUT -p icmp -j ACCEPT $iptables -A INPUT -p udp -i $INTIF --dport 67 -m state --state NEW -j ACCEPT #echo " Port 137 is for NetBIOS." $iptables -A INPUT -i $INTIF -p udp --dport 137 -j ACCEPT $iptables -A OUTPUT -o $INTIF -p udp --dport 137 -j ACCEPT #echo " Opening port 53 for DNS queries." $iptables -A INPUT -p udp -i $EXTIF --sport 53 -j ACCEPT #echo " opening Apache webserver" $iptables -A PREROUTING -t nat -i $EXTIF -p tcp --dport 80 -j DNAT --to 192.168.0.96:80 $iptables -A FORWARD -p tcp -m state --state NEW -d 192.168.0.96 --dport 80 -j ACCEPT } flush () { echo "flushing rules..." $iptables -P FORWARD ACCEPT $iptables -F INPUT $iptables -P INPUT ACCEPT echo "rules flushed" } case "$1" in start|restart) flush load ;; stop) flush ;; *) echo "usage: start|stop|restart." ;; esac exit 0 route info: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 5e0412a6.bb.sky * 255.255.255.255 UH 0 0 0 eth2 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 default 5e0412a6.bb.sky 0.0.0.0 UG 100 0 0 eth2 ifconfig: eth1 Link encap:Ethernet HWaddr 00:22:b0:cf:4a:1c inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::222:b0ff:fecf:4a1c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:79023 errors:0 dropped:0 overruns:0 frame:0 TX packets:57786 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11580918 (11.5 MB) TX bytes:22872030 (22.8 MB) Interrupt:17 Base address:0x2b00 eth2 Link encap:Ethernet HWaddr 00:0c:f1:7c:45:5b inet addr:94.4.18.166 Bcast:94.4.18.166 Mask:255.255.255.255 inet6 addr: fe80::20c:f1ff:fe7c:455b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:57038 errors:0 dropped:0 overruns:0 frame:0 TX packets:34532 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:21631721 (21.6 MB) TX bytes:7685444 (7.6 MB) 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:16 errors:0 dropped:0 overruns:0 frame:0 TX packets:16 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1517 (1.5 KB) TX bytes:1517 (1.5 KB) EDIT OK so as requested I will try and expand on my infrastructure: I previously had it setup with a Sky broadband modem router that did the DHCP and I used its web interface to port forward the web across to the web server. The network looked something like this: I have now replaced the sky modem with a dlink modem which gives the IP to the gateway server that now does the DHCP. It looks like: The internet connection is a standard broadband connection with a dynamic IP, (use zoneedit.com to keep it updated). I have tried it on each of the webservers(one Ubuntu Apache server and one WS2008 IIS7). I think there must also be an issue with my IPTable rules as it can route to my win7 box which has the default IIS7 page and that would not display when I forwarded all port 80 to it. I would be really grateful for any and all help with this. Thanks Jon

• book "Programming Role Playing Games with DirectX 2nd edition" and newer DirectX api

  - by numerical25

  I got the book "Programming Role Playing Games with DirectX 2nd edition" and I notice there are things in the book that are now considered deprecated. There is a whole Section on DirectPlay. And as much as I would like to avoid this section, I am afraid it might screw up the entire engine he is trying to build. So I was just curious to know even though DirectPlay is considered deprecated by XNA, and directX10. Is it possible to use it still in DirectX 9 ??

• Mounting NFS share between OSX and Centos VM

  - by Adam

  I'm having issues mounting an NFS share I've made on my Mac host (server) from a Centos VM (client). I'm getting a permission denied error. I have this line in /etc/exports on server: /Users/adam/Sites/ 192.168.1.223(rw) and in /etc/fstab on client: 192.168.1.186:/Users/adam/Sites/ /home/adam/Sites/ nfs rw 0 0 I'm sure this is a simple configuration issue, but I've never set up NFS properly before.

• Networked Parallel Port in Linux / KVM / QEMU

  - by korkman

  What I want to use is the "-parallel" tcp or udp option from KVM / QEMU, but I don't seem to find any server for this client. I don't serve a printer but a hardware dongle. I checked ser2net, which does provide "/dev/lp0" sharing, but it doesn't seem to work for KVM / QEMU. I suspect KVM / QEMU requires "/dev/parport0". I did rmmod lp, modprobe ppdev, linked ser2net to parport0, but it didn't work out. Perhaps ser2net is not suited for this. I tried socat as well, and I tried netcat. No success. Does anyone know any KVM / QEMU compatible parallel port server? Or did any of netcat, socat or ser2net work for you?

• Turn Windows Event Logs EVT files into Syslog to send to LogLogic

  - by TrevJen

  I have a a requirement to analyze 13gb of Windows logs by feeding it into a LogLogic Log aggregator. LogLogic is essentially Linux Syslog server, it can take a Syslog (Tcp/udp 514) feed or log on to a windows share and pull a flat file log. The only problem is that it cannot read the binary .EVT files from Windows Event logs. Normally, I would use Lasso to end the logs to a loglogic as syslog, but it has to read the logs from WMI and uses the DLLs on the log source host to format them and transmit them as syslog in the formatting that LogLogic expects. Does anyone know: A. Is there some kind of product out there to do this? or - B. Is there some way to import them into a Windows event veiwer in a way that lasso (or snare for that matter) will see them as actual real event logs on that host and forward them to the loglogic device as syslog.

• RRAS VPN Server on Windows 2008 Behind NAT

  - by Chris

  Ok, so I have kind of a funky setup, let me see if I can describe it. I have a single VMware host with a public IP address 74.xx.xx.x Inside that host, I have 3 VM's Web Server - 1 NIC - 192.168.199.20 SQL Server - 1 NIC - 192.168.199.30 RRAS/VPN Server - 2 NICs 192.168.199.40 & 192.168.199.45 Due to Limitations of my ISP, all of the VM's are connected to the host VIA NAT. I have NAT setup for the webserver so all incoming requests on 74.xx.xx.x via port 80 route to 192.168.199.20. This works fine. Now I want to set up a Windows 2008 VPN server inside this NAT network and forward the correct traffic to it. My questions are as follows? What are the TCP/UDP ports that i have to forward? What special configuration is needed on the server and clients since this is behind a NAT Any other advice would be wonderful.

• Lots of TIME_WAIT connections in netstat (Windows Server 2008)

  - by Rhys Causey

  I'm having some issues on a Windows 2008 server with some network connections not going through. For instance, in a web application on the server, we need to open a socket connection to another server, and this fails sometimes with the following message: Only one usage of each socket address (protocol/network address/port) is normally permitted I looked up the error, which led me to this page: http://msdn.microsoft.com/en-us/library/aa560610(v=bts.20).aspx, which indicates that it might be TCP/IP port exhaustion. When I perform netstat -n, I get tons of TIME_WAIT connections on port 80. Does anyone have any idea what could be causing this?

• Linux networking "jail" for a single process

  - by halp

  I need to tune up a networking app for network specific things like: make it use a DNS server different than the default one from /etc/resolv.conf make sure it does not try to connect to certain hosts/ports using tcp/udp connections I know I can get away with just modifying /etc/resolv.conf and writing some iptables rules, but going for a default DENY firewall policy for outgoing IP packets can trigger malfunctions in other services running on the server. I know I can set up a virtual machine with a whole OS and run my app there, but it seems a bit overkill. Is it possible to have a networking "jail" for a single app (think single Linux process) that could accept iptables-like rules for network traffic (think in terms of IP packets and above) allowed to and from this particular app? Maybe this is achievable through some dynamically loaded library that can deal with the networking layer, the same manner tsocks does, but more fine-grained?

• Intermittent Connection Issues to SQL Server 2008 R2 RTM

  - by Chandan Jha

  The problem I am facing is a very complex one and inspite of trying to gather a root cause of the problem, I am standing at the same place after 2 months with just bits and pieces of information.Here is a scenario: There is a windows 2003 server which uses an system DSN ODBC connection. I looked into the driver properties and it is as follows: Name Version File SQL Server 2000.86.3959.00 SQLSRV32.DLL Now, this system DSN has been given configured with TCP\IP in Network Libraries and 'determine port dynamically' is checked. Now, lets come to the database destination. It is hosted on Windows 2008 having SQL 2008 R2 RTM version 64-bit. Now, I will give you a an overview about the events that happen and whatever troubleshooting I could perform: I get an email saying 'blah blah' failed and the only message their application gets is 'cannot connect to database' I go the SQL Server logs and find the following information: Login failed for user ''. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: 10.0.0.xx Error: 18456, Severity: 14, State: 58.] A quick search shows that this error may come when an SQL Server is configured with windows authentication but its not true. We have mixed mode and connection issue is intermittent. This SQL Server is configured to run on a local system account but since we use only SQL Server accounts to connect to this, there should not be any Kerberos errors. When I run a profiler trace and see only 'existing connections', i see a lot of them coming from my client server displaying the sql user but NO hostname is shown. Textdata field shows TCP\IP information along with some arithabort and ansi-null settings. Now, I tried looking into ring connectivity buffer by using following: SELECTCAST(record AS XML) FROM sys.dm_os_ring_buffers WHERE ring_buffer_type = 'RING_BUFFER_CONNECTIVITY' One sample output is: <ConnectivityTraceRecord> <RecordType>Error</RecordType> <RecordSource>Tds</RecordSource> <Spid>118</Spid> <SniConnectionId>5124905D-D1EC-460E-AD78-201050B78C67</SniConnectionId> <OSError>0</OSError> <SniConsumerError>18452</SniConsumerError> <SniProvider>7</SniProvider> <State>1</State> <RemoteHost>10.0.0.21</RemoteHost> <RemotePort>5008</RemotePort> <LocalHost>10.1.0.38</LocalHost> <LocalPort>1433</LocalPort> <RecordTime>6/6/2012 21:14:57.527</RecordTime> <TdsBuffersInformation> <TdsInputBufferError>0</TdsInputBufferError> <TdsOutputBufferError>0</TdsOutputBufferError> <TdsInputBufferBytes>120</TdsInputBufferBytes> </TdsBuffersInformation> <TdsDisconnectFlags> <PhysicalConnectionIsKilled>0</PhysicalConnectionIsKilled> <DisconnectDueToReadError>0</DisconnectDueToReadError> <NetworkErrorFoundInInputStream>0</NetworkErrorFoundInInputStream> <ErrorFoundBeforeLogin>0</ErrorFoundBeforeLogin> <SessionIsKilled>0</SessionIsKilled> <NormalDisconnect>0</NormalDisconnect> </TdsDisconnectFlags> </ConnectivityTraceRecord> <Stack> <frame id="0">0X000000000174C34B</frame> <frame id="1">0X0000000001748FDD</frame> <frame id="2">0X0000000002461001</frame> <frame id="3">0X0000000000C47E98</frame> <frame id="4">0X00000000008015AD</frame> <frame id="5">0X0000000000801492</frame> <frame id="6">0X00000000003CBBD8</frame> <frame id="7">0X00000000003CB8BA</frame> <frame id="8">0X00000000003CB6FF</frame> <frame id="9">0X00000000008E8FB6</frame> <frame id="10">0X00000000008E9175</frame> <frame id="11">0X00000000008E9839</frame> <frame id="12">0X00000000008E9502</frame> <frame id="13">0X0000000074E437D7</frame> <frame id="14">0X0000000074E43894</frame> <frame id="15">0X00000000775A652D</frame> Somehow all the errors show error number 18452 whereas I never found this error in my SQL logs where I see only 18456. I am just stuck on a dead end because this connection issue appears intermittently. Sorry for a long question but I hope if you read this, you can make out that I tried a lot at my end before giving up.

• Graphical sandbox for pathfinding

  - by vrode

  If you needed a clean and consistent sandbox for pathfinding what would you use? I want to experiment with different pathfinding algorithms by sending virtual units (robots) around obstacles on a geometric plane. But I don't need a feature overkill like a game engine or Flash might have, just an animated report and native collision detector. I prefer it to be scripted in python, but if there are java or C++ alternatives I would appreciate them as well.

• MySql, InnoDB & Null Values

  - by pws5068

  Formerly I was using MyISAM storage engine for MySql and I had defined the combination of three fields to be unique. Now I have switched to InnoDB, which I assume caused this problem, and now NULL != NULL. So for the following table: ID (Auto) | Field_A | Field_B | Field_C I can insert (Field_A,Field_B,Field_C) Values(1,2,NULL) (1,2,NULL) (1,2,NULL) infinitely many times. How can I prevent this behavior?

• HAProxy -- pause/queue all traffic without losing requests

  - by Marc

  I basically have the same problem as mentioned in this thread -- I would like to temporarily suspend all requests to all servers of a certain backend, so that I can upgrade the backend and the database it uses. Since this is a live system, I would like to queue up requests, and send them to the backend servers once they've been upgraded. Since I'm doing a database upgrade with the code change, I have to upgrade all backend servers simultaneously, so I can't just bring one down at a time. I tried using the tcp-request options combined with removing the static healthcheck file as mentioned in that thread, but had no luck. Setting the default "maxconn" value to 0 seems to pause and queue connections as desired, but then there seems to be no way to increase the value back to a positive number without restarting HAProxy, which kills all requests that had been queued up until that point. (The "hot-reconfiguration" options using -sf and -st start a new process, which doesn't seem to do what I want). Is what I'm trying to do possible?
