• C# HttpWebResponse Error 502 Bad Gateway

  - by Sten Koning

  So i'm using this class to POST on a webpage. The server i'm trying to POST to gives me a 502 Bad Gateway error. I think it has something to do with the user agent. I've already added my firefox user agent to the request but it seems to lose it on the response. I've tried using google and found some other articles on this like this one: Error 502 (Bad Gateway) when sending a request with HttpWebRequest over SSL but I don't know how to fix it since im not that good at c#. Greetings, Sten.

• specify query timeout when using toplink essential query hint

  - by yhzs8

  Hi, For glassfish v2, I have searched through the web and I cannot find anyway to specify query timeout when using TopLink essential query hint. We have another option to migrate to EclipseLink but that is not feasible. have tried the solution in http://forums.oracle.com/forums/thread.jspa?threadID=974732&tstart=-1 but it seems the DatabaseQuery which one could set a timeout value is actually for Toplink, not TopLink essential. Do we have some other way to instruct the JDBC driver for this timeout value other than the query hint? I need to do it on query-basis and not system-basis (which is just to change the value of DISTRIBUTED_LOCK_TIMEOUT)

• SQL Server 2008 second instance times out when logging in -- but only the first time?

  - by Kromey

  This is a strange one that has plagued me for a while now. When logging in to the second instance of SQL Server 2008 on one of our database servers, we get a timeout error: Cannot connect to servername\mssqlserver2. Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server)") (This is the error message when trying to connect with Microsoft SQL Server Management Studio; other tools experience the same error, but of course say it in different ways.) Immediately re-attempting to log in works just fine, so whatever the cause it's ephemeral! This happens regardless of user or authentication type (both Windows and SQL Server authentication methods are supported on this instance). What's even weirder, though, is that the first instance on this server has never once demonstrated this problem. Server is a Windows Server 2008 R2 virtual server, hosted in Microsoft Hyper-V (host is likewise Server 2008 R2). The server has 2GB of RAM, and seems to regularly be using 90% of that -- could low memory be the cause of this issue? I could see this second instance -- which is not used very often yet -- being swapped out to disk, and then taking too long to load back into memory to respond in time to the connection request, but I'd rather have more than just my own hunch before I go scheduling a downtime for this server (the first instance is used regularly) and then just throwing extra resources at it in the blind hope that the problem goes away.

• IDbTransaction Rollback Timeout

  - by Ben

  I am dealing with an interesting situation where I perform many database updates in a single transaction. If these updates fail for any reason, the transaction is rolled-back. IDbTransaction transaction try { transaction = connection.BeginTransaction(); // do lots of updates (where at least one fails) transaction.Commit(); } catch { transaction.Rollback(); // results in a timeout exception } finally { connection.Dispose(); } I believe the above code is generally considered the standard template for performing database updates within a transaction. The issue I am facing is that whilst transaction.Rollback() is being issued to SQL Server, it is also timing out on the client. Is there anyway of distinguishing between a timeout to issue the rollback command and a timeout on that command executing to completion? Thanks in advance, Ben

• Graceful handling of server timeout in BlazeDS

  - by Rydell

  I have a flex client that makes service calls to a tomcat server running BlazeDS. I would like to gracefully handle server session timeouts in this environment. I do have security constraints on the service, so the client authenticates against a remote object by initializing a ChannelSet based on the destination, and then logging in using that ChannelSet. After the user is authenticated, if they go get a (long) cup of coffee, their session will inevitably time out. I would like the client to detect the timeout, and return the user back to the login page, with the appropriate informational messages. But I am having difficulty finding the best way to detect this timeout from the client. Is it possible, or must I have the server throw an error when the timeout occurs? Thanks!

• Java Mail timeout & connectiontimeout handling

  - by Gnanam

  Hi, I'm using JavaMail to send email requests to an SMTP server. I would like to set both "mail.smtp.connectiontimeout" and "mail.smtp.timeout" properties within my code. Programmatically, I want to catch both when timeout and/or connectiontimeout operations are reached in Java and handle things accordingly. Handling in the sense, I need to retry the same email once again the next time. How do I handle this in Java/JavaMail? Is it possible to catch & handle this timeout operations?

• HttpWebRequest timeout in Windows service

  - by googler1

  I am getting a timeout error while starting my Windows service. I am tring to download an XML file from a remote system which causes a timeout during the service OnStart. This is the method I am calling from OnStart: public static StreamReader GetResponseStream() { try { EventLog.WriteEntry("Epo-Service_Retriver", "Trying ...", EventLogEntryType.Information); CookieContainer CC = new CookieContainer(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create( Utils.GetWeeklyPublishedURL()); request.Proxy = null; request.UseDefaultCredentials = true; request.KeepAlive = true; //THIS DOES THE TRICK request.ProtocolVersion = HttpVersion.Version10; // THIS DOES THE TRICK request.CookieContainer = CC; WebResponse response = request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); EventLog.WriteEntry("Epo-Service_Retriver", "Connected to Internet...", EventLogEntryType.SuccessAudit); return reader; } } Is there any possibility to avoid this timeout?

• SqlBulkCopy unusual TimeOut Error

  - by ChrisHDog

  I have a SqlBulkCopy operation that is taking data from an MS-Access 2007 database (via OleDbConnection) and using SqlBulkCopy to transfer that data to a SQL Server database. This has previously been working and continues to work for one MS-Access database, but not the other. I get the error message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It is hard to believe it is a timeout ast the oledbCommand.CommandTimeout = 0 the sqlBulkCopy.BulkCopyTimeout = 0 and on either side (MS-Access and SQL Server the timeouts have now been set to 0). Are there other issues/exceptions that the above error message could be hiding? Is there a way to determine what the base cause of a sqlBulkCopy.WriteToServer exception is (there doesn't appear to be any inner exceptions etc...)

After some searching, i found that 'c:\windows\bootstat.dat' file holds the timeout value for 'Time to display recovery options when needed'... but, i am not able to decode the .dat file or edit that file.. any suggestions would he helpful for me.. Thanks in advance

• Default IPv6 route on debian squeeze does not come up after boot

  - by Georg Bretschneider

  I have a problem with my default IPv6 route not coming up after boot on a Debian Squeeze system. This is my config (/etc/network/interfaces): # Loopback device: auto lo iface lo inet loopback iface lo inet6 loopback # device: br0 auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 88.198.62.xx broadcast 88.198.62.63 netmask 255.255.255.224 gateway 88.198.62.33 up route add -net 88.198.62.32 netmask 255.255.255.224 gw 88.198.62.33 br0 iface br0 inet6 static address 2a01:4f8:131:10x::2 netmask 64 gateway 2a01:4f8:131:100::1 up route -A inet6 add 2a01:4f8:131:100::1/59 dev br0 My inet comes up alright, but I have to exec the route command manually after boot to make IPv6 work. Otherwise I can't even reach my gateway. This is the output of ip -6 route show after boot: 2a01:4f8:131:10x::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 unreachable fe80::/64 dev lo proto kernel metric 256 error -101 mtu 16436 advmss 16376 hoplimit 4294967295 fe80::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 I already tried it with: up ip -6 route add 2a01:4f8:131:100::1 dev br0 up ip -6 route add default via 2a01:4f8:131:100::1 dev br0 in /etc/network/interfaces, but with the same results. If I execute those commands manually on my shell, everything starts working nicely. And yes, I tried with post-up instead of up, too. Only other changes I made was to activate ip forwarding for IPv6, because I want to run some LXC containers on that system.

• Two DHCP interfaces asigned to two default gateways to OS

  - by user140600

  I have a Ubuntu box that has two networking interfaces (eth0 and wlan0). They are both configured for DHCP in /etc/network/interfaces, but they both assign a default gateway: /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto wlan0 iface wlan0 inet dhcp wireless-essid test Result of route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 172.16.1.1 0.0.0.0 UG 100 0 0 wlan0 0.0.0.0 10.0.0.1 0.0.0.0 UG 100 0 0 eth0 10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 172.16.1.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0 How can I set up /etc/network/interfaces to have only one default gateway, on the interface I want? Worst case scenario, how can I at least control which one gets on top on the route -n command, each boot? Note: This box will travel a lot, and will be connected to different networks, so I don´t know in advance the IP addresses/ranges it will have. Sometimes the default gw interface will be eth0. Sometimes it will be wlan0 ... So, this needs to be kind of automatic ...

• What happens if an asynchronous delegate call never returns?

  - by RichardHowells

  I found a decent looking example of how to call a delegate asynchronously with a timeout... http://www.eggheadcafe.com/tutorials/aspnet/847c94bf-4b8d-4a66-9ae5-5b61f049019f/basics-make-any-method-c.aspx. In summary it uses WaitOne with a timeout to determine if the call does not return before the timeout expires. I also know that you should have an EndInvoke to match each BeginInvoke. So what happens if the wait timeout expires? We (presumably) DON'T want to call EndInvoke as that will block. The code can go on to do 'other things', but have we leaked anything? Is there some poor thread someplace blocked waiting for a return that's never going to happen? Have we leaked some memory where the result-that-will-never-return was going to be placed?

• PXE-E32 TFTP Open Timeout While Attempting to PXE Boot from Windows Deployment Services

  - by bschafer

  I'm running Windows Deployment Services on Windows Server 2008 R2 on top of an ESX 4.0 box. This is the only function of this VM instance, although it had previously functioned as an AD Domain Controller. My DHCP server is running on our primary Domain Controller, which is also Server 2008 R2, but running on metal. Everything was working perfectly until we recently had our backup generator fail during a power outage, causing all of our servers and networking equipment to lose power for a period of time. When we brought all of our equipment back up, everything was working as expected except for WDS. Our network is split up into several different vlans. Now, depending on which vlan the client computer is on, it's behaving differently when attempting to PXE boot into WDS. Our servers are located on the 10.55.x.x vlan, which, due to the nature of it, has no DHCP server active in it. The first computer we plugged in happened to be in the 10.99.x.x vlan, which is supposed to be reserved for network management devices (i.e. switches), but we've been using it occasionally otherwise. That computer gave us PXE-E11 ARP Timeout errors. When we moved to a different computer on the 10.19.x.x vlan (for general purpose use), it finally gets an IP from DHCP, but it presents us with a very stumping PXE-E32 TFTP Open Timeout error. Before the power outage, it didn't matter which vlan a device was on; it would PXE boot and image just fine. I've made no changes to anything server-side. Everything is configured exactly the same way it was on my WDS and DHCP servers as before the power outage. I've tried several different computers, including different models. All of this, combined with the quirky behavior depending on the vlan, makes me think something went wrong in one or more of our switches, probably because of the power outage. Unfortunately, I'm no network guy, and I know very little about how to configure our switches properly. Is this an issue with switches, etc? If so, how can I fix it? Is there some magical option I'm not aware of? Does anybody out there have any hunches? I've pretty much exhausted my ideas. Our main switch is an HP Procurve 5406. We also have 3x HP Procurve 4208 switches. The ESX Server is an HP ProLiant DL380 G6. The WDS VM is currently using the VMXNET3 network adaptor, but we've also tried the E1000 adaptor.

• Snmp configuration giving me timeout, no response

• Tracking SQL Server 2008 Timeout Errors

  we got some connections timeouts running a stored procedure in a SQL Server 2008 instance. after a while, the DB started to work as usual, and there weren't any additional timeout errors. So I'm trying to get additional info about the error. Does SQL server 2008 have any kind of error log that I can look into? Do exist any auditing/logging features that I can activate to trace the error (if it happens again)?

• Google chrome proxy authentication dialogue timeout

  - by Nihar Sarangi

  I am on a network that uses LDAP proxy for authentication based on a username and password. Whenever I start Google Chrome, it pops up with a proxy authentication dialogue, but the dialogue disappears automatically after variable amount of time (sometimes it stays for 5 seconds some times less than 1 second). I have found the same issue with Chromium also. Is there any configuration I can set to control this timeout, or say, auto-authenticate with my authentication details from the shell or DE (Gnome3 on Arch)?

• What are some reputable merchant account providers for high risk payment web sites?

  I am helping to set up an online cigar web site. However, it has become a real pain to take payments online since tobacco is considered a "high-risk" item and nobody will provide a merchant account to process the payments. It looks like there are companies that specialize in high-risk merchant accounts. I was wondering if anybody could recommend a high-risk merchant account and payment processing provider?
