• SCCM SP2 - OOB Management Certificates Problems

  - by Achinoam

  I have a vPro client computer with AMT 4.0. It was importeed successfully via the Import OOB Computers wizard, and after sending a "Hello- packet" it became provisioned. (The SCCM GUI displays AMT Status: Provisioned). But when I try to perform power operations on this machine, they always fail with the following lines in the log: AMT Operation Worker: Wakes up to process instruction files 7/29/2009 10:59:29 AM 2176 (0x0880) AMT Operation Worker: Wait 20 seconds... 7/29/2009 10:59:29 AM 2176 (0x0880) Auto-worker Thread Pool: Work thread 3884 started 7/29/2009 10:59:29 AM 3884 (0x0F2C) session params : https:/ / amt4.domaindemo.com:16993 , 11001 7/29/2009 10:59:29 AM 3884 (0x0F2C) ERROR: Invoke(invoke) failed: 80020009argNum = 0 7/29/2009 10:59:31 AM 3884 (0x0F2C) Description: A security error occurred 7/29/2009 10:59:31 AM 3884 (0x0F2C) Error: Failed to Invoke CIM_BootConfigSetting::ChangeBootOrder_INPUT action. 7/29/2009 10:59:31 AM 3884 (0x0F2C) AMT Operation Worker: AMT machine amt4.domaindemo.com can't be waken up.

What could be the reason for this failure? What is the problematic definition for the certificate? Thank you in advance!!!

• Why can't I connect to remote Microsoft SQL Server through SSH tunnel?

  - by Alexander

  I have at home a D-Link DIR-615 C1 router with DD-WRT. I set up the SSH server on the router, and log on through an SSH2-RSA passphrase-protected key. That router is the gateway between the local network and the internet. One of the computers on that network has Microsoft SQL Server 2008 installed, with TCP/IP protocol enabled through port 1433. I've set up port forwarding on the router, so that remote connections are possible and are, in fact, working (some developers log on remotely without problems). I am part of another network, that has internet access through a proxy server, which only has ports 80 and 443 opened. I can't connect to that MSSQL server on that remote server because 1433 port is closed on this network. I connected (using Putty) through 443 port to my router's SSH server, and set up 2 tunnels. One is for RDP (3389), and it's working. The other is for 1433 port, to connect to the server. I can't connect through the SSH tunnel to the MS SQL Server, neither through telnet, or through GUI clients. Am I missing something? Additional details: on connect, I get this error from SQL Server Management Studio: TITLE: Connect to Server Cannot connect to localhost:14330. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 3) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=3&LinkId=20476 BUTTONS: OK The tunnel is configured like this: L14330 192.168.0.103:1433 192.168.0.103 is the permanent address of the SQL Server on the LAN. I also successfully forwarded TCP traffic of 3389 port to that IP, so tunneling is working to that IP address. When connecting without tunnel, through Microsoft SQL Server Management Studio, using the same method the connection establishes. Too bad my proxy doesn't allow 1433 port traffic, I wouldn't have this headache.

• telnet to 3389 connects, RDP remote desktop app bails ?

  - by scott_lotus

  I can TELENT 192.168.10.10 3389 and get a connection. But RDP client to 192.168.10.10 immedietly bails (i.e less then 1 sec) "connect" button greys briefly, RDP app remains on screen. Have tried these from many nodes on the subnet to 192.168.10.10 with same result. On 192.168.10.10 Allow Remote Desktop is enabled. On 192.168.10.10 windows firemall is off. Im connecting from the same subnet i.e no firewall hardware / routers in the way. AV software is installed but other nodes on same subnet allow RDP connection using exact same AV settings (network group profile) Checked 192.168.10.10 for any additonal AV software or local firewall products. Im sure non exist. Checked regedit to ensure 3389 was the port set for listening. Seems to be an XP problem (sp3) ( 2 nodes on the my LAN have this issue) and many work fine. Thanks for any help Scott

• Where should you put constants and why?

  - by Tim Meyer

  In our mostly large applications, we usually have a only few locations for constants: One class for GUI and internal contstants (Tab Page titles, Group Box titles, calculation factors, enumerations) One class for database tables and columns (this part is generated code) plus readable names for them (manually assigned) One class for application messages (logging, message boxes etc) The constants are usually separated into different structs in those classes. In our C++ applications, the constants are only defined in the .h file and the values are assigned in the .cpp file. One of the advantages is that all strings etc are in one central place and everybody knows where to find them when something must be changed. This is especially something project managers seem to like as people come and go and this way everybody can change such trivial things without having to dig into the application's structure. Also, you can easily change the title of similar Group Boxes / Tab Pages etc at once. Another aspect is that you can just print that class and give it to a non-programmer who can check if the captions are intuitive, and if messages to the user are too detailed or too confusing etc. However, I see certain disadvantages: Every single class is tightly coupled to the constants classes Adding/Removing/Renaming/Moving a constant requires recompilation of at least 90% of the application (Note: Changing the value doesn't, at least for C++). In one of our C++ projects with 1500 classes, this means around 7 minutes of compilation time (using precompiled headers; without them it's around 50 minutes) plus around 10 minutes of linking against certain static libraries. Building a speed optimized release through the Visual Studio Compiler takes up to 3 hours. I don't know if the huge amount of class relations is the source but it might as well be. You get driven into temporarily hard-coding strings straight into code because you want to test something very quickly and don't want to wait 15 minutes just for that test (and probably every subsequent one). Everybody knows what happens to the "I will fix that later"-thoughts. Reusing a class in another project isn't always that easy (mainly due to other tight couplings, but the constants handling doesn't make it easier.) Where would you store constants like that? Also what arguments would you bring in order to convince your project manager that there are better concepts which also comply with the advantages listed above? Feel free to give a C++-specific or independent answer. PS: I know this question is kind of subjective but I honestly don't know of any better place than this site for this kind of question. Update on this project I have news on the compile time thing: Following Caleb's and gbjbaanb's posts, I split my constants file into several other files when I had time. I also eventually split my project into several libraries which was now possible much easier. Compiling this in release mode showed that the auto-generated file which contains the database definitions (table, column names and more - more than 8000 symbols) and builds up certain hashes caused the huge compile times in release mode. Deactivating MSVC's optimizer for the library which contains the DB constants now allowed us to reduce the total compile time of your Project (several applications) in release mode from up to 8 hours to less than one hour! We have yet to find out why MSVC has such a hard time optimizing these files, but for now this change relieves a lot of pressure as we no longer have to rely on nightly builds only. That fact - and other benefits, such as less tight coupling, better reuseability etc - also showed that spending time splitting up the "constants" wasn't such a bad idea after all ;-)

• SSH broken, segfault error 4

  - by trampi

  i cannot connect to my server via ssh, it throws me a "server unexpectedly closed connection" after entering the password. in var/log/messages the only noteable message is: Apr 14 17:41:23 s15410270 kernel: sshd[3602]: segfault at c0 ip 7f0801acbdb0 sp 7fff0adff860 error 4 in libc-2.8.so[7f0801a87000+14f000] Apr 14 17:41:29 s15410270 kernel: sshd[3606]: segfault at c0 ip 7f75f9463db0 sp 7fff027971f0 error 4 in libc-2.8.so[7f75f941f000+14f000] This message appears after a log in attempt via ssh or via sftp Its a SuSE Linux server. I'm looking for help where to start to search for the error, i can still act as root via a serial console. edit: "server unexpectedly closed connection" only appears if i enter the correct password!

• Where can I find logs for SFTP?

  - by Jake

  I'm trying to set up sftp-server but the client is getting an error, Connection closed by server with exitcode 1 /var/log/auth.log (below) doesn't help much, how can I find out what the error is? I'm running Ubuntu 10.04.1 LTS sshd[27236]: Accepted password for theuser from (my ip) port 13547 ssh2 sshd[27236]: pam_unix(sshd:session): session opened for user theuser by (uid=0) sshd[27300]: subsystem request for sftp sshd[27236]: pam_unix(sshd:session): session closed for user theuser Update: I've been prodding this for a while now, I've got the sftp command on another server giving me a more useful error. Request for subsystem 'sftp' failed on channel 0 Couldn't read packet: Connection reset by peer Everything I've found on the net suggests this id a problem with sftp-server but when I remove the chroot from sshd config I can access the system. I assume this means sftp-server is accessible and set up correctly.

• phpredis + pconnect

  - by john smith

  I am using phpredis on my php based website. The webserver I am using is a the simplest apache apt-get installation, no configuration involved, as this is only a development environment. The issue I am facing is that basically, while using phpredis, there is no difference between "connect" and "pconnect" commands: they both create a new connection everytime, as I can see from the "info" command on redis-cli. Now, I am pretty sure it is because of the apache configuration and the fact that it probably (most likely) is a multi-threaded env, therefore can't enstablish a single connection. My question is basically for when I will turn into production: what would the best choice of a webserver be to avoid this problem? I remember using lighttpd with thousands of users and still get only a very few (like 2 or 3) connections on mongoDB. Any ideas? Thanks in advance.

• mysqld crashes on any statement

  - by ??iu

  I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement.

• Severe latency only on one machine and only when accessing intranet site

  - by Joe M.

  I have one desktop machine that is having consistently high latency only when trying to load a page from an intranet site. Using the Chrome Developer Tools, the site shows a "Waiting" time of 4-5 seconds each page load. Other machines have <50ms, and the problem machine loads regular internet sites with <1s latency, so the problem is only on one machine and only when accessing the intranet site. This is a small business and all the hosts are on 192.168.0.1/24 I would have suspected a connection issue with the problem machine but normal internet sites are not having latency. Then I would have looked at connection issues with the intranet web server but other machines are not having latency to it. What else can I look at to troubleshoot this?

• How can I restrict SSH access when the source IP is dynamic

  - by Supratik

  Hi I want to protect SSH access to our live web server from all IP's except our office static IP. There are some employees who connects to this live server from their dynamic IP's. So, it is not always possible for me to change in the iptables rule in live server whenever the dynamic IP of the employee changes. I tried to put them in office VPN and allowed only SSH access from office IP but the office connection is slow in compared to our employee's private internet connection, moreover it adds an extra overhead to our office network. Is there any way I can solve this problem ?

• Can I make ssh tell me which control file it would use for multiplexing?

  - by Ryan Thompson

  I am using the following options in my ~/.ssh/config in order to enable connection multiplexing: ControlMaster auto ControlPath ~/.ssh/control/master-%r@%h:%p However, this has the annoying problem that the first shell to connect to a particular server must be the last to disconnect, because it is the master connection that all the other connections are using. So if you log out of the master, it appears to just hang. To solve this, I would like to wrap ssh with a script that checks if the control master file exists, and if not, starts a master ssh process in the background. Then it would start a slave ssh session. In order to accomplish this, my script would have to determine the path to the control file that ssh would use. This would entail parsing the ssh command line options and config files and implementing the logic for determining the ControlPath. Is there any way to just ask ssh what path it would use, so I can check it?

• How to achieve reliable Gigabit Ethernet Link with my Acer Aspire Revo R3610?

  - by The Operator

  I want to stream HD movies over my wired Gigabit LAN from my PC to my Acer Aspire Revo R3610. It's connected with a 3ft Cat5e patch cable to my Netgear GS605v2 Switch. The PC acting as File Server is connected at 1Gbps to the Switch. Network driver options are set to defaults, including automatic speed/duplex negotiation on both machines. The Revo will not connect to my Network Switch at 1Gbps - the OS reports that it reverts to 100Mbps either shortly after connection or immediately upon connection. Through a process of elimination (trying different drivers, patch cables, ports on the switch, and other 1Gbps-capable devices connected to the Network switch which successfully achieve 1Gbps links and performance) I have drawn the conclusion there is either a Hardware or Software (Driver) issue with the Revo itself. I have performed tests using Windows 7 and Ubuntu 9.10. Can anyone offer insight on Gigabit Ethernet with the Revo?

• How to find source of 301/302 redirect loop? Heroku GoDaddy Zerigo

  - by user179288

  this should be a relatively simple problem but I'm having trouble.I hope this is the right forum to post on as I've seen people get booted off stack-overflow for this sort of thing. I've setup a web app on heroku (cedar stack) at my-web-app.herokuapp.com and I'm trying to direct my-domain.com and www.my-domain.com to it. As per instructions on the heroku documentation, I've set my-domain.com to redirect (forwarding) to www.my-domain.com and then set a C-Name from www.my-domain.com to my-web-app.herokuapp.com. But the C-Name doesn't seem to be working right and is sending back to my-domain.com, causing a loop and I can't work out why. I first configured these setting at GoDaddy.com where I registered the domain but then tried to avoid the problem by using Heroku's Zerigo DNS add-on, setting the nameservers on GoDaddy to the ones given for Zerigo. However the problem remains.

• Setup and configure a MVC4 project for Cloud Service(web role) and SQL Azure

  - by MagnusKarlsson

  I aim at keeping this blog post updated and add related posts to it. Since there are a lot of these out there I link to others that has done kind of the same before me, kind of a blog-DRY pattern that I'm aiming for. I also keep all mistakes and misconceptions for others to see. As an example; if I hit a stacktrace I will google it if I don't directly figure out the reason for it. I will then probably take the most plausible result and try it out. If it fails because I misinterpreted the error I will not delete it from the log but keep it for future reference and for others to see. That way people that finds this blog can see multiple solutions for indexed stacktraces and I can better remember how to do stuff. To avoid my errors I recommend you to read through it all before going from start to finish.The steps:Setup project in VS2012.

• DB auto failover in c# does not work when the principal server physically goes offline

  - by user62521

  I'm setting up DB auto failover in C# with SQL Server 2008 and I have a 'high safety with automatic failover mirror' using a witness setup and my connection string looks like "Server=tcp:DC01; Failover Partner=tcp:DC02; database=dbname; uid=sewebsite;pwd=somerndpwd;Connect Timeout=10;Pooling=True;" During testing, when I turn off the SQL Server service on the principal server the auto failover works like a charm, but if I take the principal server offline (by shutting down the server or killing the network card) auto failover does not work and my website just times out. I found this article where the second last post suggests that its because we are using named pipes which does not work when the principal goes offline, but we force TCP in our connection string. What am I missing to get this DB auto failover working?

• Understanding Asynchronous Programming with .NET Reflector

  - by Nick Harrison

  When trying to understand and learn the .NET framework, there is no substitute for being able to see what is going on behind at the scenes inside even the most confusing assemblies, and .NET Reflector makes this possible. Personally, I never fully understood connection pooling until I was able to poke around in key classes in the System.Data assembly. All of a sudden, integrating with third party components was much simpler, even without vendor documentation!With a team devoted to developing and extending Reflector, Red Gate have made it possible for us to step into and actually debug assemblies such as System.Data as though the source code was part of our solution. This maybe doesn’t sound like much, but it dramatically improves the way you can relate to and understand code that isn’t your own.Now that Microsoft has officially launched Visual Studio 2012, Reflector is also fully integrated with the new IDE, and supports the most complex language feature currently at our command: Asynchronous processing.Without understanding what is going on behind the scenes in the .NET Framework, it is difficult to appreciate what asynchronocity actually bring to the table and, without Reflector, we would never know the Arthur C. Clarke Magicthat the compiler does on our behalf.Join me as we explore the new asynchronous processing model, as well as review the often misunderstood and underappreciated yield keyword (you’ll see the connection when we dive into how the CLR handles async).Read more here

• Beginners advice on Small business network disk(s)

  - by Rob

  We are having 10 PCs used by various user and presently use one network disk (a LaCie NAS) for all our data. Everything is Windows Vista and our collective IT hardware knowledge is minimal. This worked well generally. However, recently the disk freqently loses connection from the network (2-3 times per week) and the only way back seems to be the "turn it off and back on" trick. This obviously cant be any good for the disk. I understand that there are various more sophisticated ways of storing data and was wondering what people would recommend. One of the worries is obviously disk failure (either in part or as a whole) and the lack of continued availability due to network issues. I would guess that a disk which replicates data wouldnt work as a sole solution due to the network connection, but dont know what hardware (and/or software) would/could work in our case. In terms of size, we are looking at very small amounts, ie. less than 500 GB in total.

Tried reaching customer care representative to figure out why data connection is not working, but the robots (Interactive Voice Response systems) never allowed me to reach a human. After digging through the settings I found empty list of APN (Access Point Names) is the reason for not able to connect to internet. Not sure what caused APN list to vanish but I tried to create a new one that matches with the settings required for AT & T mobile. To my surprise I found that the newly created APN is also not shown in the APN list. Well there is something wrong with the phone – my APN’s are not shown as well as the newly created one is also not displayed. A simple Google search on this problem shown many forum discussions list and the solution to resolve the issue is to restart the phone. As soon as I restarted my phone the APN list is automatically populated and I’m able to connect to internet on my mobile.

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

• Help with the RT3290 Wireless adapter

  - by Potek

  I know there is a lot of questions about RT3290 wireless adapter, but I read many many of them and noone helped me with my problem. So, I have the HP Pavilion dm1 laptop and I installed Xubuntu 13.10 on it. During the instalation it poped up that I'm able to connect to the internet via network adapter. I did it obviously, but it worked for like 5 seconds, then it said that network connection is down and I couldn't connect to my router, even if i could actually see network connections avaible. Then (when installation ended) I rebooted my computer. My network was avaible! I could connect and browse the internet smoothly. Next day I turned on my laptop and I saw my wireless connection is no longer avaible, so I plugged laptop to the internet via Ethernet cable and started to explore internet searching solution for my problem. I did this: How do I get a Ralink RT3290 wireless card working? And I was able to connect BUT my kernel started to panic every time I started Mozilla or any program that is connecting to the internet. Every tip i searched was almost the same as the link above. I tried to do this many ways. I even Reinstalled Xubuntu to do everything with clear system but the same thing happened. THEN I installed Linux Mint to check whether it is a major or just Xubuntu problem. Linux Mint responded even worse, because I wasn't even able to use terminal (I clearly messed something up). I would really, really appreciate every help, because I do want to solve this problem and finally be able to use Xubuntu/Ubuntu. I'm waiting for advice from anyone patiently. If anyone wants some details, just tell me which ones.

• How to capture a Header or Trailer Count Value in a Flat File and Assign to a Variable

  - by Compudicted

  Recently I had several questions concerning how to process files that carry a header and trailer in them. Typically those files are a product of data extract from non Microsoft products e.g. Oracle database encompassing various tables data where every row starts with an identifier. For example such a file data record could look like: HDR,INTF_01,OUT,TEST,3/9/2011 11:23 B1,121156789,DATA TEST DATA,2011-03-09 10:00:00,Y,TEST 18 10:00:44,2011-07-18 10:00:44,Y B2,TEST DATA,2011-03-18 10:00:44,Y B3,LEG 1 TEST DATA,TRAN TEST,N B4,LEG 2 TEST DATA,TRAN TEST,Y FTR,4,TEST END,3/9/2011 11:27 A developer is normally able to break the records using a Conditional Split Transformation component by employing an expression similar to Output1 -- SUBSTRING(Output1,1,2) == "B1" and so on, but often a verification is required after this step to check if the number of data records read corresponds to the number specified in the trailer record of the file. This portion sometimes stumbles some people so I decided to share what I came up with. As an aside, I want to mention that the approach I use is slightly more portable than some others I saw because I use a separate DFT that can be copied and pasted into a new SSIS package designer surface or re-used within the same package again and it can survive several trailer/footer records (!). See how a ready DFT can look: The first step is to create a Flat File Connection Manager and make sure you get the row split into columns like this: After you are done with the Flat File connection, move onto adding an aggregate which is in use to simply assign a value to a variable (here the aggregate is used to handle the possibility of multiple footers/headers): The next step is adding a Script Transformation as destination that requires very little coding. First, some variable setup: and finally the code: As you can see it is important to place your code into the appropriate routine in the script, otherwise the end result may not be as expected. As the last step you would use the regular Script Component to compare the variable value obtained from the DFT above to a package variable value obtained say via a Row Count component to determine if the file being processed has the right number of rows.

• Two Routers, Two Internet (1 Open, 1 PPTP) - Routing?

  - by SomeUser

  Hi there, I'm trying to setup two routers - one to route specific sites to a always-on PPTP VPN connection, the other for open internet access w/ firewall. First router is connected to Internet w/ built-in firewall. Second router is connected to a PPTP VPN connection. I was going to connect a wire between the routers and would like some insight on how to get both groups of systems (connected to each router) to talk between automatically. Even better would be to setup one gateway for certain sites and another for general Internet. The other option is to default all sites to the net and shoot others to the gateway or vice versa... Any insight so I can get a better grasp of this? Thanks!
