• How to copy files from shadow copy with long source path

  - by Jake

  The files and folders in my shared network drive (set up with DFS) were mass deleted. Currently I am trying to recover the files from the shadow copy "Previous Version". Problem is, thousands of files are deeply nested with long paths making the file path too long. When copying, it shows the dialog "Source Path Too Long". My guess is that the file path just barely hits the limit when saved into the network drive, but shadaw copy service appends the date and time to the folders so the path character limit is exceeded. How else can I copy the files from shadow copy?

• Amazon EC2 migration from one region to the other

  - by Gnanam

  I'm using the following Amazon EC2 resources in the US East (Virginia) region: 1 Running Instance 1 Elastic IP 2 EBS Volumes 100 EBS Snapshots 1 Key Pair 2 Security Groups 5 My Own AMIs (customized based on my application stack) My instance is based on Linux distribution (CentOS) and my AMIs are S3-backed. Both EBS volumes are mounted on this running instance. We're planning to migrate our deployment to US-West region. Because Amazon EC2 resources are not shared across regions, my questions are: What are all the factors that I need to consider in advance? What are all the recommended & different ways of migrating each EC2 resources from one region to the other? Are there any hidden risks involved during and/or after the migration? Experts ideas/suggestions/recommendations on this are highly appreciated.

• Adding editFTPnetPRO to SSIS package causes error message

  - by gfrizzle

  I'm trying to add some secure FTP code to an SSIS package. I've used the EnterpriseDT product successfully on other .NET projects, so I wanted to incorporate it into an SSIS 2008 package I'm working on. If I create a Script Task (VB), edit the script, choose Project | Add Reference, and select the editFTPnetPRO.dll file, it comes back with this error: No template information found. See the application log in Event Viewer for more details. To open Event Viewer, click Start, click Control Panel, double-click Administrative Tools, and then double-click Event Viewer. The application log doesn't contain any pertinent details. I have no idea what this is trying to tell me. I've gone down a couple dead ends searching for this error message and following the prescribed fixes, but nothing has fixed it yet. Any idea what might be going wrong? P.S. - I tried the devenv.exe /installvstemplates fix, which didn't change anything. Update: Here is the error captured in the SSIS package when you try to run it: Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.IO.FileNotFoundException: Could not load file or assembly 'edtFTPnetPRO, Version=6.3.1.20, Culture=neutral, PublicKeyToken=0dce1ad63760d80b' or one of its dependencies. The system cannot find the file specified. Where is it looking for this file? I tried copying it to the project direcory, the bin folder, and the C:\WINDOWS\Microsoft.NET\Framework\v2.0.nnnn folder, but it still can't find it, and it won't tell me where it's looking.

• Visual C++ Assembly link library troubles

  - by Sanarothe

  Hi. I'm having a problem having my projects built in VC++ Express 2008... I'm using a library, irvine32.inc/lib. INCLUDE Irvine32.inc works for me at school (On already configured VS environments) by default, but at home (Windows 7 x64) I'm having a boatload of issues. My original post here was that a file that irvine32.inc referenced, in the same folder, 'could not be opened.' Added irvine folder to the include path for specific project, progress. Then I was getting an error with mt.exe, but a suggestion on the MSDN suggested turn off antivirus, and now project does build but when I run a program that does NOT reference anything in irvine32, it tells me repeatedly that my project has triggered a breakpoint, and allows me to continue or break. Continue just pops the same window, break loads another popup telling me that "No symbols are loaded for any call stack frame. Source code cannot be displayed." This popup lets me view the disassembly. I tested it with and without working statements, it just throws the same breakpoint on the first line of code. Now, if I run the program when it DOES require something from the include file, in this case, DumpRegs: INCLUDE Irvine32.inc .data .code main PROC mov ebx,1000h mov eax,1000h add eax,ebx call DumpRegs main ENDP END main This gives me 1main.obj : error LNK2019: unresolved external symbol _DumpRegs@0 referenced in function _main@0 1C:\Users\Cameron\csis165\Lab8_CCarroll\Debug\Lab8_CCarroll.exe : fatal error LNK1120: 1 unresolved externals This does NOT happen when I build a project from the book author's examples, which has the same include statement. I'm baffled. :(

• Apache2 BufferedLogs On - anybody using it ?

  - by Qiqi

  Greetings, I am wondering, whether anybody is using BufferedLogs On with Apache2 and found any issues ? Feature is marked as experimental, but for many years now, so I guess it's rather pretty stable. I am running some servers with constrained disk IO capacity at the moment, so I turned it on hoping that even a small benefit could help in the long run ;-) I do have several to several hundreds requests per seconds so by my thoughts there is really no need to write to log after each request, cause honestly I don't think that my filesystem is the best handler for many unnecessary writes. (OCFS2 shared among several DomUs in the Xen)

• One Mac computer with multiple network connections?

  - by Kyle Lowry

  I have a Mac (OS X 10.5) that I would like to connect to a dedicated/isolated Internet connection (one that is not connected to the LAN), and a LAN. The LAN is set up with its own, separate, Internet connection which is shared by several dozen computers (and is quite slow). I want to set it up so that the Mac uses its own dedicated Internet connection (on a different account with a different company) for its Internet access, but can still access the local area network as well. How can I configure the Mac & the network to allow this?

• Run Rails 3 app on a Rails 2 server/machine?

  - by chucknelson

  I'm trying to run a Rail 3 (3.0.10) app on a shared joyent smartmachine server (I don't have root access) which has Rails 2 (2.3.11) installed , and I'm not sure what to do after I freeze my Rails 3 app with bundle install --deployment. It seems like with the Rails 3 and bundler gems not being installed on the server locally, my app isn't even recognizing the local version of Rails I have frozen with my app. Has anyone gotten this to work, or have any advice? The server runs Apache, and I think I can get lighttpd installed too - but I'd rather stay with Apache if I can. Also, if it matters, Passenger is not an installed gem either...and I'm not sure I can freeze that with my app. Update 11/30/2011 12:30 PM EST Bundler is not installed on this server, either. Not sure if having that would enable the new Rails 3 "freeze" (bundle --deployment) to work or not...

• "Catch-All" access log with Apache Virtual Hosts?

  - by pix0r

  I have many virtual hosts set up on a web server, each one having its own error and access log. The relevant lines of httpd.conf are something like this: ErrorLog /var/log/httpd-error.log LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined CustomLog /var/log/httpd-access.log combined NameVirtualHost *:80 <VirtualHost *:80> ServerName myhost.com ServerAlias www.myhost.com DocumentRoot /var/www/myhost.com/htdocs ErrorLog /var/www/myhost.com/log/error.log CustomLog /var/www/myhost.com/log/access.log combined </VirtualHost> # ... many more VirtualHosts Currently, I'm getting some random errors in /var/log/httpd-error.log, but I'm getting nothing in /var/log/httpd-access.log. Is it possible to have ALL accesses and errors duplicated to a shared logfile? Is it possible to do this without adding new entries to every single VirtualHost?

• How can I register a custom protocol with xdg ?

  - by julien

  I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

• Rename a file with perl

  - by perlnoob

  I have a file in a different folder I want to rename in perl, I was looking at a solution earlier that showed something like this: for (<backup.rar>) { my $file = $_; my $new = $_ 'backup'. @test .'.rar'; rename $file, $new or die "Error, can not rename $file as $new: $!"; } however backup.rar is in a different folder, I did try putting "C:\backup\backup.rar" in the < above, however I got the same error. C:\Program Files\WinRARperl backup.pl String found where operator expected at backup.pl line 35, near "$_ 'backup'" (Missing operator before 'backup'?) syntax error at backup.pl line 35, near "$_ 'backup'" Execution of backup.pl aborted due to compilation errors. I was using # Get time my @test = POSIX::strftime("%m-%d-%Y--%H-%M-%S\n", localtime); print @test; To get the current time, however I couldn't seem to get it to rename correctly. What can I do to fix this? Please note I am doing this on a windows box.

• How to elegantly handle ReturnUrl when using UrlRewrite in ASP.NET 2.0 WebForms

  - by Brian Kim

  I have a folder with multiple .aspx pages that I want to restrict access to. I have added web.config to that folder with <deny users="?"/>. The problem is that ReturnUrl is auto-generated with physical path to the .aspx file while I'm using UrlRewrite. Is there a way to manipulate ReturnUrl without doing manual authentication check and redirection? Is there a way to set ReturnUrl from code-behind or from web.config? EDIT: The application is using ASP.NET 2.0 WebForms. I cannot use 3.5 routing. EDIT 2: It seems like 401 status code is never captured. It returns 302 for protected page and redirects to login page with ReturnUrl. It does not return 401 for protected page. Hmm... Interesting... Ref: http://msdn.microsoft.com/en-us/library/aa480476.aspx This makes things harder... I might have to write reverse rewrite mapping rules to regex match ReturnUrl and replace it if it doesn't return 401... If it does return 401 I can either set RawUrl to Response.RedirectLocation or replace ReturnUrl with RawUrl. Anyone else have any other ideas?

• PHPUnit and autoloaders: Determining whether code is running in test-scope?

  - by pinkgothic

  Premise I know that writing code to act differently when a test is run is hilariously bad practise, but I may've actually come across a scenario in which it may be necessary. Specifically, I'm trying to test a very specific wrapper for HTML Purifier in the Zend framework - a View Helper, to be exact. The HTML Purifier autoloader is necessary because it uses a different logic to the autoloaders we otherwise have. Problem require()-ing the autoloader at the top of my View Helper class, gives me the following in test-scope: HTML Purifier autoloader registrar is not compatible with non-static object methods due to PHP Bug #44144; Please do not use HTMLPurifier.autoload.php (or any file that includes this file); instead, place the code: spl_autoload_register(array('HTMLPurifier_Bootstrap', 'autoload')) after your own autoloaders. Replacing the require() with spl_autoload_register(array('HTMLPurifier_Bootstrap', 'autoload')) as advertised means the test runs fine, but the View Helper dies a terrible death claiming: Zend_Log[3707]: ErrorController caught LogicException "Passed array does not specify an existing static method (class 'HTMLPurifier_Bootstrap' not found)" (Our test folder structure is slightly different to our Zend folder structure by necessity.) Question(s) After tinkering with it, I'm thinking I'll need to pick an autoloader-loading depending on whether things are in the test scope or not. Do I have another option to include HTMLPurifier's autoloading routine in both cases that I'm not seeing due to tunnel vision? If not, do I have to find a means to differentiate between test-environment and production-environment this with my own code (e.g. APPLICATION_ENV) - or does PHPUnit support this godawful hackery of mine natively by setting a constant that I could check whether its been defined(), or similar shenanigans? (My Google-fu here is weak! I'm probably just doing it wrong.)

• CARP: two machines think they're the master, but only on one interface

  - by Conor McDermottroe

  I have two machines, each configured identically as a firewall/load balancer for a busy website. I have set them up with CARP and pfsync on both the internal and external interfaces. The internal interface is behaving as expected (primary listed as MASTER and secondary listed as BACKUP) On both machines, the network interfaces are as follows: em0 - External interface bge0 - Internal interface bge1 - Crossover connection between both machines carp0 - Shared external interface for CARP carp1 - Shared internal interface for CARP I've rewritten the IP addresses and MAC addresses below. The networks are as follows: 10.0.1.0/24 - External network 10.0.2.0/24 - Internal network 10.0.3.0/24 - Crossover network Here's the output from ifconfig on the primary: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4> ether [SNIP] inet 10.0.1.10 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet 100baseTX <full-duplex> status: active bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.2.10 netmask 0xffffff00 broadcast 10.0.2.255 media: Ethernet 1000baseT <full-duplex> status: active bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.3.10 netmask 0xffffff00 broadcast 10.0.3.255 media: Ethernet 1000baseT <full-duplex> status: active lo0: flags=80c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33152 pfsync0: flags=0<> metric 0 mtu 1460 pfsync: syncdev: bge1 syncpeer: 10.0.3.11 maxupd: 128 carp0: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.1.5 netmask 0xffffff00 carp: MASTER vhid 1 advbase 1 advskew 0 carp1: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.2.5 netmask 0xffffff00 carp: MASTER vhid 2 advbase 1 advskew 0 And here's the /etc/rc.conf excerpt from the primary: defaultrouter="10.0.1.1" network_interfaces="em0 bge0 bge1 lo0 pfsync0" cloned_interfaces="carp0 carp1" ifconfig_em0="inet 10.0.1.10 netmask 255.255.255.0 media 100BaseTX mediaopt full-duplex" ifconfig_bge0="inet 10.0.2.10 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_bge1="inet 10.0.3.10 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_carp0="vhid 1 pass [SNIP] 10.0.1.5/24" ifconfig_carp1="vhid 2 pass [SNIP] 10.0.2.5/24" pfsync_enable="YES" pfsync_syncdev="bge1" pfsync_syncpeer="10.0.3.11" And here's the output on the secondary: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4> ether [SNIP] inet 10.0.1.11 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet 100baseTX <full-duplex> status: active bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.2.11 netmask 0xffffff00 broadcast 10.0.2.255 media: Ethernet 1000baseT <full-duplex> status: active bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.3.11 netmask 0xffffff00 broadcast 10.0.3.255 media: Ethernet 1000baseT <full-duplex> status: active lo0: flags=80c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33152 pfsync0: flags=0<> metric 0 mtu 1460 pfsync: syncdev: bge1 syncpeer: 10.0.3.10 maxupd: 128 carp0: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.1.5 netmask 0xffffff00 carp: MASTER vhid 1 advbase 1 advskew 20 carp1: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.2.5 netmask 0xffffff00 carp: BACKUP vhid 2 advbase 1 advskew 20 And here's the /etc/rc.conf excerpt from the secondary: defaultrouter="10.0.1.1" network_interfaces="em0 bge0 bge1 lo0 pfsync0" cloned_interfaces="carp0 carp1" ifconfig_em0="inet 10.0.1.11 netmask 255.255.255.0 media 100BaseTX mediaopt full-duplex" ifconfig_bge0="inet 10.0.2.11 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_bge1="inet 10.0.3.11 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_carp0="vhid 1 pass [SNIP] advskew 20 10.0.1.5/24" ifconfig_carp1="vhid 2 pass [SNIP] advskew 20 10.0.2.5/24" pfsync_enable="YES" pfsync_syncdev="bge1" pfsync_syncpeer="10.0.3.10" What I don't understand is, the carp status on carp0 is MASTER on both machines when the status on carp1 is as it should be (MASTER on the primary and BACKUP on the secondary).

• At what point does Active Directory and Domain Services become necessary? [closed]

  - by user970638

  I see time and time again such services running in a business environment with only 10 users. Everyone in the office authenticates with the DC and interacts with a shared drive where files and documents are stored. I can't help but think...reeeeealy? But I don't know, that's why I'm asking. To me it seems like you need to reach a certain threshold of size and needs before you throw a DC into the mix. ie: a 20+ user business (and growing) with permission requirements that separate the sales team from accounting. Thoughts?

• mod_rewrite/GoDaddy problem

  - by John Deerhake

  Ok, so I really don't know much about mod_rewrite and I'm looking over the apache docs and still not figuring this out. Here is my htaccess (which is mostly just copy & pasted from a site I found): .htaccess in base dir: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ public/ [L] RewriteRule (.*) public/$1 [L] </IfModule> .htaccess in /public dir: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?url=$1 [PT,L] </IfModule> Basically I'm using the above htaccess files on my current test server and it works great and exactly like I would expect (everything gets seamlessly redirected to public dir). Now when I throw this on my GoDaddy hosting account i get "Internal Server Errror". I've done some searching and I'm fairly certain I should be able to use mod_rewrite with GoDaddy. I suspect this is because I'm not using the base directory to host the site in. The site is in in the folder html/myapp/ (where html is the base directory) and i have a subdomain set up in GoDaddy to look in that folder.

• Why does a pdf file download result in varying bytes logged, all with sc-status 200

  - by Pat James

  I have a mojoportal CMS installation on an IIS7 server where users are reporting problems downloading a pdf file. It always downloads fine for me and most others, either displaying in browser or in Adobe Reader. Using logparser to query the IIS logs, all the responses are status 200 (OK) or 304 (Not modified), but the bytes sent vary quite a bit. Sometimes zero, some 211, some about half the full file size of 27059, and lots in between. Plenty show the full size of 27059. Do these other entries for smaller byte counts represent errors of some kind, correlating with the problems reported? Is this likely to be a browser/client issue or a server side problem? If there is any other info that would be helpful let me know. This is a shared hosting server though so I am somewhat limited in what I can dig into on the server.

I have shared 1 link on my Facebook profile like below: http://www.webdeveloper.com/ (It's not only Facebook. It can be any domain having link to another domain). 2) When I click on this link from my Facebook profile, then this website will open in new tab. 3) I want to calculate time difference in miliseconds or microseconds between below two events: First Event: Time of clicking link "http://www.webdeveloper.com/" from my Facebook profile. Second Event: Time of completely loading webpage of "http://www.webdeveloper.com/". Thank you in advance.

• Why not all users can log in to a network computer by using <network computer name>/<user name> form

  - by Haris

  There is a file server in my office that is not connected to my office LAN. In this server there are folders that are shared. This server is connected to a switch and a wireless router. Everyone who wants to access this server uses wireless network connection. They log in to this server by providing user name and password registered to the server. Some people can log in to my office file server by providing user name in (the server name)/(user name) format, while other must use (the server IP address)/(user name) format. Why is it like this? I need everyone can access the file server by providing user name in (the server name)/(user name) format. I have tried to change the %SystemRoot%\system32\drivers\etc\hosts file, as some suggested, but it won't work. Any other suggestion?

• Is there a simple way to backup and restore all Microsoft SQL Server database objects related to a p

  - by Nathan Hartley

  I would like to backup, not only the databases that belong to a particular application living on a shared server, but also, those things that get stored outside of the database; the server accounts, jobs, maintenance plans and whatever else I can't think of at the moment. This backup should be complete enough that it's corresponding restore will recreate the entire application on a different SQL server. This seems like a problem others must have dealt with in the past. So before I embark on creating custom Powershell scripts for each application, I have come to ask you... Can you help?

• Monitor file selection in explorer (like clipboard monitoring) in C#

  - by Christian

  Hi, I am trying to create a little helper application, one scenario is "file duplication finder". What I want to do is this: I start my C# .NET app, it gives me an empty list. Start the normal windows explorer, select a file in some folder The C# app tells me stuff about this file (e.g. duplicates) How can I monitor the currently selected file in the "normal" windows explorer instance. Do I have to start the instance using .NET to have a handle of the process. Do I need a handle, or is there some "global hook" I can monitor inside C#. Its a little bit like monitoring the clipboard, but not exactly the same... Any help is appreciated (if you don't have code, just point me to the right interops, dlls or help pages :-) Thanks, Chris EDIT 1 (current source, thanks to Mattias) using SHDocVw; using Shell32; public static void ListExplorerWindows() { foreach (InternetExplorer ie in new ShellWindowsClass()) DebugExplorerInstance(ie); } public static void DebugExplorerInstance(InternetExplorer instance) { Debug.WriteLine("DebugExplorerInstance ".PadRight(30, '=')); Debug.WriteLine("FullName " + instance.FullName); Debug.WriteLine("AdressBar " + instance.AddressBar); var doc = instance.Document as IShellFolderViewDual ; if (doc != null) { Debug.WriteLine(doc.Folder.Title); foreach (FolderItem item in doc.SelectedItems()) { Debug.WriteLine(item.Path); } } }

• NSFetchedResultsController: changing predicate not working?

  - by icerelic

  Hi, I'm writing an app with two tables on one screen. The left table is a list of folders and the right table shows a list of files. When tapped on a row on the left, the right table will display the files belonging to that folder. I'm using Core Data for storage. When the selection of folder changes, the fetch predicate of the right table's NSFetchedResultsController will change and perform a new fetch, then reload the table data. I used the following code snippet: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"list = %@",self.list]; [fetchedResultsController.fetchRequest setPredicate:predicate]; NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } [table reloadData]; However the fetch results are still the same. I've NSLog'ed "predicate" before and after the fetch, and they were correct with updated information. The fetch results stay the same as initial fetch (when view is loaded). I'm not very familiar with the way Core Data fetches objects (is there a caching system?), but I've done similar things before(changing predicates, re-fetching data, and refreshing table) with single table views and everything went well. If someone could gave me a hint I would be very appreciated. Thanks in advance.

• Strange behavior in networking between 64bit and 32bit

  - by Rob

  I'm having a strange behavior about my network setup. I have 2 laptops, one (Lenovo) with Windows 7 Professional 64-bit and another (Acer) with Windows 7 Ultimate 32-bit and a wireless router. I'm connecting these 2 using the router but with a strange behavior. I can ping both machines, as well as the router, but when i try to access their shared folders (\\computer_name\shared_folder) the connection starts to fail and I need to reboot both machines to get it working again. But this only happens sometimes, sometimes it works.

• How can I share a Windows 7 library with anonymous access without using a Homegroup?

  - by Triynko

  The "homegroup" feature is useless, because it requires a password, and therefore doesn't support anonymous, no-hassle access to shares from devices such as my Sony Bravia TV and non-Windows7 machines. So I turned off homegroup and reverted to the standard shared folders protocol. I'd like to share my Music "Library", so I can play files from my TV through the Surround Sound System, but there seems to be no option to share a library folder other than through a homegroup. I don't want to have to individually share the folders that belong to the library, because that would defeat the purposes of the library, which is to manage which folders are included in the library while also providing an easily accessible view of them all at once. Does anyone know how to share a Windows 7 library without that useless homegroup feature?

  I have a Cisco 1841 configured for VPN connections of two types: Peer-to-peer for partners' routers (IPsec) — using different crypto isakmp key and crypto map with set peer, set transform-set, match address for every peer (same map name, different priorities). That crypto map name is added to the WAN interface. Client access (PPTP) — using vpdn-group with accept-dialin protocol pptp. Now, a new partner wants to connect using vpnc client. The latter needs IPSec ID (group name) and IPSec secret in addition to username and password. I guess that IPSec secret is pre-shared key that can be specified in crypto isakmp key on Cisco. But I could not find any VPN tutorials involving groups. Hence, my questions: How to add IPSec ID (group name) and IPSec secret on Cisco router for vpnc connections? Should I add a new crypto map matching all addresses as well? Is it possible to add this configuration without breaking the existing setup? Thank you.

• apache tomcat loadbalancing clustering on ubuntu

  - by user740010

  i am facing a problem in clustering the tomcat with apache as a loadbalancer using mod_jk on ubuntu. i have install apache2 on my ubuntu 11.04 and i have downloaded tomcat7 created two copies and kept them at two different location. 1st one is at /home/net4u/vishal/test/tomcatA 2nd one is at /home/net4u/vishal/test1/tomcatB i have made following changes to server.xml file in /conf folder 1. <Server port="8205" shutdown="SHUTDOWN"> 2. <Connector port="8280" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> 3.<Connector port="8209" protocol="AJP/1.3" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcatB"> 4. <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/> similarly i have modified other tomcat i.e tomcatA server.xml content of the server.xml is as follow: -- <!--The connectors can use a shared executor, you can define one or more named thread pools--> <!-- <Executor name="tomcatThreadPool" namePrefix="catalina-exec-" maxThreads="150" minSpareThreads="4"/> --> <!-- A "Connector" represents an endpoint by which requests are received and responses are returned.
