• What is Apache Synapse?

  - by Aren B

  My website keeps getting hit by odd requests with the following user-agent string: Mozilla/4.0 (compatible; Synapse) Using our friendly tool Google I was able to determine this is the hallmark calling-card of our friendly neighborhood Apache Synapse. A 'Lightweight ESB (Enterprise Service Bus)'. Now, based on this information I was able to gather, I still have no clue what this tool is used for. All I can tell is that is has something to do with Web-Services, and supports a variety of protocols. The Info page only leads me to conclude it has something to do with proxies, and web-services. The problem I've run into is that while normally I wouldn't care, we're getting hit quite a bit by Russian IPs (not that russian's are bad, but our site is pretty regionally specific), and when they do they're shoving wierd (not xss/malicious at least not yet) values into our query string parameters. Things like &PageNum=-1 or &Brand=25/5/2010 9:04:52 PM. Before I go ahead and block these ips/useragent from our site, I'd like some help understanding just what is going on. Any help would be greatly appreciated :)

• Ionic Isapi Rewrite error on IIS6, Windows 2003 Server

  - by EsiX

  First of all my setup is a VPS running Windows 2003 Server with multiple domains on it IIS 6, Plesk IsapiRewrite4.ini RewriteLogLevel 3 RewriteCond %{HTTP_HOST} ^mydomain.com$ RewriteRule ^/(.*)$ http://www.mydomain.com/$1 [R] This is one of their basic examples. Ionic is installed and setup proper because if I use another rule (a simpler one ... like the one following) it works instant # IsapiRewrite4.ini # RewriteLogLevel 3 # # This ini file illustrates the use of a redirect rule. # Any incoming URL that starts with an uppercase W # will be redirected to the specified server. RewriteRule ^/(W.*)$ http://server.dyndns.org:7070/$1 [R] This one works in the TestDriver tool and none of them gives any error or warnings in TestParse tool, but it doesn't do a thing on the webserver... The fact that one rule works means that the isapi module works. I am using the last version. RedirectRule http://mydomain.com/someplace/somefile.html http://www.mydomain.com/howto/someplace/anotherfile.html [I,L] Both examples were taken from http://iirf.codeplex.com/Wiki/View.aspx?title=Redirection&referringTitle=Home So my IsapiRewrite4.ini needs to do this two tasks: auto transform and redirection for a number of urls. Can you help out.. I really don't know what I'm doing wrong.

• Remote SQL server connection failure

  - by Sevki

  I am trying to connect to my MSSQL server 2008 web instance and im failing horribly... i get the error 26 and before you jump on me i have done these Check the spelling of the SQL Server instance name that is specified in the connection string. Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections over the TCP or named pipes protocols. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. Make sure that you have configured the firewall on the server instance of SQL Server to open ports for SQL Server and the SQL Server Browser port (UDP 1434). Make sure that the SQL Server Browser service is started on the server. in addition to theese i have disabled the firewall completely and tried other ports nothing works the same credentials work on the server but not on the client. this is the exact error message 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.

• Verification of files on backup media - after the backup

  - by Greg Sansom

  I have a system in place where I back up my work files daily to a portable hard drive. I actually have two portable hard drives - one is stored off-site and I swap them regularly. I also keep my family photos and other historical files backed up, but I only back the photos up occasionally (ie when I have new photos). The backup media is for backup only, and it is unlikely I will ever read the files from the backup media unless a disaster occurs and I lose the master. It worries me that my backed up files could become corrupt without me knowing it. It is also feasible that my master files could become corrupt, and eventually the corrupt files would be replicated to the backup media. I'm currently using Cobian Backup, but I'm open to alternatives. Is there a tool I can use to confirm that the backed up files are identical to the files that were first copied? I know it would be possible to generate a checksum and periodically validate the backup files against the original checksum, but I'm looking for a tool which will do this automatically.

• How do I easily repair a single unreadable block on a Linux disk?

  - by Nelson

  My Linux system has started throwing SMART errors in the syslog. I tracked it down and believe the problem is a single block on the disk. How do I go about easily getting the disk to reallocate that one block? I'd like to know what file got destroyed in the process. (I'm aware that if one block fails on a disk others are likely to follow; I have a good ongoing backup and just want to try to keep this disk working.) Searching the web leads to the Bad block HOWTO, which describes a manual process on an unmounted disk. It seems complicated and error-prone. Is there a tool to automate this process in Linux? My only other option is the manufacturer's diagnostic tool, but I presume that'll clobber the bad block without any reporting on what got destroyed. Worst case, it might be filesystem metadata. The disk in question is the primary system partition. Using ext3fs and LVM. Here's the error log from syslog and the relevant bit from smartctl. smartd[5226]: Device: /dev/hda, 1 Currently unreadable (pending) sectors Error 1 occurred at disk power-on lifetime: 17449 hours (727 days + 1 hours) ... Error: UNC at LBA = 0x00d39eee = 13868782 There's a full smartctl dump on pastebin.

• Atlassian Crucible very slow on large repository

  - by Mitch Lindgren

  Hi everyone, My company has been running a trial of Atlassian Crucible for some months now. For repositories where it's working properly, users have given very positive feedback about the tool. The problem I'm having is that we have several different projects, each with its own repository, and some of those repositories are very large. One repository in particular has a large number of branches and probably around 9,000 files per branch. Browsing that repository in Crucible is extremely slow. Crucible is running on a CentOS VM. The VM has 4GB of RAM, and I've set Crucible's maximum at 3GB, of which it is currently using 2GB. I've brought this up in a support ticket with Atlassian, and they suggested the following: In particular because you have a rather large SVN repository you will likely find that Fisheye will be creating a large index file on disk. To help improve performance a few things you can try are: Increasing the available memory available to Fisheye (see the document above). Migrating to an external database: confluence.atlassian.com/display/FISHEYE/Migrating+to+an+External+Database Excluding files and directories from your index that aren't needed: confluence.atlassian.com/display/FISHEYE/Allow+(Process) (Sorry for not hyperlinking; don't have the rep.) I've tried all of these things to an extent, but so far none have helped greatly. I was originally running Crucible on a Windows box with 2GB of RAM using the built in HSQL DB. Moving to MySQL on CentOS saw a performance increase for some repositories, and made Crucible much more stable, but did not seem to help much with our biggest repository. There are only so many files/branches I can exclude from indexing while maintaining the tool's usefulness. That being the case, does anyone have any tips on how to speed up Crucible on large repositories, without investing in insanely powerful hardware? Thanks! Edit: To clarify, since I didn't mention it explicitly above, I am using FishEye.

• How to connect to local instance of SQL Server 2008 Express

  - by Billy Logan

  I just installed SQL Server 2008 Express on my windows 7 machine. I previously had 2005 on here and used it just fine with the old SQL Server Management Studio Express. I was able to connect with no problems to my PC-NAME\SQLEXPRESS instance. I uninstalled 2005 and SQL Server Management Studio Express. I then installed SQL Server 2008 Express on my machine and elected to have it install SQL Server Management Studio. Now, when I try to connect to PC-NAME\SQLEXPRESS (with Windows Authentication, like I always did), I get the following message: Cannot connect to PC-NAME\SQLEXPRESS. 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=-1&LinkId=20476 When I went to the help link it mentions, the help page suggests the following: * Make sure that the SQL Server Browser service is started on the server. * Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. I did try starting the SQL Server Browser, but don't see that the Surface Area Configuration is installed with this express version. I had seen another user with an almost exact same issue that was missing the database engine on install. If that were the case how could i test for that and where would i go to download that install. Thanks in advance, Billy

• Gentoo Linux useful utilities

  - by Alakdae

  I want to make a list of utilities that come in handy in Gentoo (general Linux tools available in all distributions also appreciated). What tools and commands do you use and consider helpful in administration of a Gentoo server? I will update the list with command from answers from time to time. eclean Utility for cleaning distfiles and binary packages. Usage example: eclean distfiles Usage example output: Cleans out the files in /usr/portage/distfiles. Pretty handy. Package: app-portage/gentoolkit eix Very useful tool for getting information about a package. Similar to "emerge -s" but much faster and more precise. Usage example: eix gentoolkit Usage example output: Show information about package such as: available versions, masked versions, installed versions and description. Package: app-portage/eix eix-test-obsolete Check system for obsolete, redundant, uninstalled entries in package.keywords, package.mask, package.unmask, package.use and package.cflags Usage example: eix-test-obsolete Usage example output: Shows non-matching entries, redundant entries, and uninstalled entries. Package: app-portage/eix equery Another very useful tool for getting information about packages (listing package files, checking which files belong to which package and much more) Usage example: equery b emerge Usage example output: Show which packages installed a file called emerge Package: app-portage/gentoolkit genlop Utility for extracting information about emerged ebuilds Usage example: genlop -l --date yesterday Usage example output: Show a list of packages that have been emerged yesterdayPackage: app-portage/genlop glsa-check Checks system if it's affected by GLSAs (security issues) Usage example: glsa-check -l affected Usage example output: List of GLSA that the system is affected by.

• HTTP Upload Problems

  - by jfoster

  We are running a marketplace on ColdFusion8 and IIS with a widely geographically distributed user base and have been receiving complaints of issues with some HTTP uploads. Most of the complaints are coming from geographically distant locations from our main datacenter on the US east coast. I've attempted to upload the same 70MB file from a US West coast test server to both our main site and a backup running the same code on a different network route and I saw the same issues fairly consistently in both places, so I've ruled out the code, route, and internal network errors. I've also tested uploads using both the native cf upload tag and a third party tool called SaFileUp. I saw the same issues with both upload tools, so I also don't think this is necessarily a ColdFusion problem. I don't have any problems uploading the test file from the East coast to other east coast servers, so I'm beginning to think that the distance between our users and our equipment is a factor. I've also found that smaller files are more likely to succeed than large ones (< 10MB) I tried the test upload with both IE and FF and did notice a difference in the way that the browsers seemed to handle packet errors. IE seemed to have a tough time continuing an upload after dropped / bad packets, whereas FF seemed to have the ability to gracefully resume an upload after experiencing packet problems. Has anyone experienced similar issues? Is there anything we can do on our side to make uploads more forgiving to packet loss or resumable after an error? A different upload tool etc… Do we need upload servers in more than one location to shorten the network routes between clients and servers? Does anyone think that switching uploads to SSL will help (no layer7 packet sniffing may lead to a smoother upload). Thanks.

• How do you verify a restore?

  - by Nic

  What tool(s) would you use to verify that a restored file structure is whole and complete? My environment is a Windows Server 2008 file server. (We use tape for backup, but that is inconsequential.) I am specifically looking for a tool that will: Record the names of all files and folders below a specified directory Optionally calculate checksums of each file encountered Save this index in a human-readable format Compare the index against restored data and show differences Some background: I recently had to replace the disks in our file server. The upgrade was scheduled to start 36 hours after the most recent full backup, so I created a differential backup. However, it turns out that one of our applications was clearing the archive bit on files saved to the server, so these were not included in the differential backup. I was unaware of this until my users reported some files as missing. Aside from this, are there any other common methods for validating the integrity of a restore? I am frequently told that testing backups by restoring them is the only way to know that backups are working, but how do you deal with the case where it works 99% correctly and the other 1% silently fails?

• Easy text re-wrapping

  - by AmV

  I'm looking for a tool that allows me to easily re-wrap text (i.e. remove line breaks, but not paragraph breaks from a text selection or a text field), and that works in my browser (Chrome) and on Windows. Bonus points for anything that works outside the browser, and that works in-place (i.e. that doesn't require copy-pasting the text through a separate window or using something like http://www.textfixer.com/tools/remove-line-breaks.php) Browser extensions, GreaseMonkey scripts or applications that also work on Linux and/or Mac (or even better, that are multi-platform) are all welcomed. Here is an example of how the tool should behave. If I have the following in a text field: This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com I'd like to be able to, for example, select the text, and, with a keyboard shortcut, convert it to: This is a test for SuperUser.com. This is a test for SuperUser.com. This a test for SuperUser.com. This is a test for SuperUser.com This is a test for SuperUser.com. This is a test for SuperUser.com. This a test for SuperUser.com. This is a test for SuperUser.com Thanks in advance!

• SSD, AHCI and write performance

  - by Dan

  We've started to deploy SSD drives to our developers workstations. At this moment we're having the unpleasant surprise that the systems using the new SSDs often freeze, with the HDD activity led blinking or being continuously on. Benchmarks shows read speeds around 180 MB/s, but write speeds around 5 MB/s. All developers are using Windows 7 Enterprise, 64 bit, SP1. One of our developers suggested (based on his experience) the following sequence: backup the workstation use a tool to completely erase the SSD make sure AHCI is enabled in BIOS install Windows restore from backup So far, this procedure seems to work (we're still testing, but write speed seems to be 120 MB/s). There are some questions in this context: why do we have to completely reinstall Windows? Is it possible to clean the SSD without reinstalling Windows? Is there a reliable tool? If AHCI was disabled when Windows was installed and we enable it, shouldn't this be enough to correct the write performance issue? If we have to completely erase the SSDs, does this mean the SSDs we've received were used before (SH)? I'm wondering this because the package I've got was open (I didn't think about it at that time, as I considered one of my coworkers simply took a peek inside the package). Has anyone seen a similar problem before?

• Problem importing pictures from a digital camera with Windows 7

  - by snark

  Hi, Since I'm using Windows 7 (Beta, then RC, now RTM), I have issues when I download pictures from my digital cameras. It happens with my 2 cameras: a Canon Powershot S2 IS and a Canon Ixus 80 IS. When I plug a camera (any of them) to a USB port and switch it on in Play mode, the Autoplay function of Windows 7 starts with this screen: I select "Import pictures and videos" to call the native Windows 7 tool. It searches a bit for pictures to download from the camera and starts the transfer. However, during the transfer, I often get errors like this one: If I use "Try again", it works fine the second time and the picture is retrieved correctly. It's very annoying when it happens 20 or 30 times in a 500-picture download. I cannot leave it running standalone, as I have to watch for the errors and click on "Try again". Any idea what is causing these errors? I tried changing the USB port (normally the cameras are connected via a USB hub but it happens also when I connect them directly to a MB USB port) and the USB cable, but no success. I also checked the SD card by connecting them with a card reader and running a ChkDsk on them but it found no errors on the cards. Update: No problem when I copy the pictures manually with the Windows Explorer. And no problem either when I access the card with a reader. The builtin import tool of Windows is convenient as it sorts the pictures automatically by date (1 folder per day). And this is the way I sort my pictures

• mac terminal run a file of commands

  - by Ilan Tal

  I am coming from Linux and trying to get a Mac to do what I want it to do. The question is what is the best tool to use. I want to mount (unmount) several remote disks. If I go into a terminal I can do the trick by mount -t smbfs //username:pass@addr /Users/me/RemoteDisks/mnt1 Since I want to mount several disks I would like to put all of the information into a file, store it in Documents/subfolder and make a link to it on the desktop (or somewhere better, if there is a better place). At the moment I have manually run the appropriate command in the terminal and the remote disk is mounted and I see its contents. What I need is a one click method to run a file to mount all the disks. I tried Apple script but that didn't like my commands. I don't know exactly what it is expecting to see and perhaps Apple script is the wrong tool. I have no problems in Linux, but the Mac is new to me and I don't know what I should be using. Thanks, Ilan

• Error occurs when Win 7 opens

  - by user1708748

  I have an HP customized laptop barely a week old. Since yesterday it has given me an error message while opening Windows- every time. it gives error code (0x40000015) refers to an exception at location (0x0033fa4d). I have 64 bit Win 7 and had been transferring files. And installing programs. 8 GB Ram 650 gb hard drive. Not sure which program caused this. Q's that I've seen with this error code all say it occurs while shutting down. A search re. error code told me to use a removal tool. When I downloaded the tool,I got a message saying it is not compatible with Windows 7. Is that really possible? Search re. location code yielded nothing I am an intermediate user. I can restore to an earlier time but I don't know which program might do this again.

• Different versions of iperf for windows give totally different results

  - by Albert Mata

  Measuring TCP output from a Windows client to Solaris server: WXP SP3 with iperf 1.7.0 -- returns an average around 90Mbit Same client, same server but iperf 2.0.5 for windows -- returns an average of 8.5 Mbit Similar discrepancies have been observed connecting to other servers (W2008, W2003) It's difficult to get to some conclusions when different versions of the same tool provide vastly different results. Example below: C:\tempiperf -v (from iperf.fr) iperf version 2.0.5 (08 Jul 2010) pthreads C:\tempiperf -c solaris10 Client connecting to solaris10, TCP port 5001 TCP window size: 64.0 KByte (default) [ 3] local 10.172.181.159 port 2124 connected with 10.172.180.209 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.2 sec 10.6 MBytes 8.74 Mbits/sec Abysmal perfomance, but now I test from the same host (Windows XP SP3 32bit and 100Mbit) to the same server (Solaris 10/sparc 64bit and 1Gbit running iperf 2.0.5 with default window of 48k) with the old iperf C:\temp1iperf -v iperf version 1.7.0 (13 Mar 2003) win32 threads C:\temp1iperf.exe -c solaris10 -w64k Client connecting to solaris10, TCP port 5001 TCP window size: 64.0 KByte [1208] local 10.172.181.159 port 2128 connected with 10.172.180.209 port 5001 [ ID] Interval Transfer Bandwidth [1208] 0.0-10.0 sec 112 MBytes 94.0 Mbits/sec So one iperf with a 64k window says 8.75Mbit and the old iperf with the same window size says 94.0Mbit. These results are constant through repeated tests. From my testing launching iperf(old) with window size "x" and iperf(new) with window size "x" instead of producing the same or very close results produce totally different results. The only difference I see is the old compiled as win32 threads vs. pthreads but parallelism (-P 10) appears to work in both. Anyone has a clue or can recommend a tool that gives results I can trust?? EDIT: Looking at traces from (old) iperf it sets the TCP Window Scale flag to 3 in the SYN packet, when I run the (new) iperf this is set to 0 in the initial packet. A quick analysis of the window size through the exchange shows the (old) iperf moving back and forth but mostly at 32k while the (new) iperf mostly keeps at 64k. Maybe it will help somebody to connect the dots.

• Free web-based software for team collaboration/documentation

  - by Jason Antman

  Looking for some advice here, as my search has turned up to be pretty fruitless. My group (9 people - SAs, programmers, and two network guys) is looking for some sort of web tool to... ahem... "facilitate increased collaboration" (we didn't use a buzzword generator, I swear). At the moment, we have an unified ticketing system that's braindead, but is here to stay for political/logistical reasons. We've got 2 wikis ("old" and "new"), neither of which fulfill our needs, and are therefore not used very often. We're looking for a free (as in both cost and open source) web-based tool. Management side: Wants to be able to track project status, who's doing what, whether deadlines are being met, etc. Doesn't want full-fledged "project management" app, just something where we can update "yeah this was done" or "waiting for Bob to configure the widgets". TeamBox (www.teambox.com) was suggested, but it seems almost too gimmicky, and doesn't meet any of the other requirements: Non-management side: - flexible, powerful wiki for all documentation (i.e. includes good tables, easy markup, syntax highlighting, etc.) - good full text search of everything (i.e. type in a hostname and get every instance anyone ever uttered that name) - task lists or ToDo lists, hopefully about to be grouped into a number of "projects" - file uploads - RSS or Atom feeds, email alerts of updates We're open to doing some customizations (adding some features, notification/feeds, searching, SVN integration, etc.) but need something F/OSS that will run under Apache. My conundrum is that most of the choices I've found so far fall into one of these categories: project management/task tracking with poor wiki/documentation/knowledge base support wiki with no task tracking support ticketing system with everything else bolted on (we already have one that we're stuck with) code-centric application (we do little "development", mostly SA work) Any suggestions? Or, lacking that, any comments on which software would be easiest to add the lacking features to (hopefully ending up with something that actually looks good and works well)?

• Deleting files in the windows installer folder

  - by qw3n

  How do you clean up the windows/installer folder on a xp machine. I looked on different forums, but the tool many mention is no longer officially supported and from what I understand not specifically for this task. Also, I was confused on which tool to use or how to use it. The reason I ask this is I have an older computer with ~86gb drive and ~80gb of is being used by the windows/installer. I'm assuming that at least some of these are glitches and shouldn't be in there. Note that the person who uses the computer mentioned trying to interrupt an install at some point and I don't know if this has anything to do with it. Also, there are not that many programs installed on this computer ~25. Also, I know that similar questions has been asked several times already, but the accepted answer Is it safe to delete from C:\Windows\Installer? is mainly talking about is it safe to delete (along with most of the duplicates). I'm asking how to find and delete the files that shouldn't be there especially since were not talking 5-10gb but something that practically fills the entire hard drive, and for those who are wondering I ran CCleaner, but it doesn't seem to check this folder.

• Apache rewrite rules and special characters

  - by Massimo

  I have a server where some files have an actual %20 in their name (they are generated by an automated tool which handles spaces this way, and I can't do anything about this); this is not a space: it's "%" followed by "2" followed by "0". On this server, there is an Apache web server, and there are some web pages which links to those files, using their name in URLs like http://servername/file%20with%20a%20name%20like%20this.html; those pages are also generated by the same tool, so I (again!) can't do anything about that. A full search-and-replace on all files, pages and URLs is out of question here. The problem: when Apache gets called with an URL like the one above, it (correctly) translates the "%20"s into spaces, and then of course it can't find the files, because they don't have actuale spaces in their names. How can I solve this? I discovered than by using an URL like http://servername/file%2520name.html it works nicely, because then Apache translates "%25" into a "%" sign, and thus the correct filename gets built. I tried using an Apache rewrite rule, and I can succesfully replace spaces with hypens with a syntax like this: RewriteRule (.*)\ (.*) $1-$2 The problem: when I try to replace them with a "%2520" sequence, this just doesn't happen. If I use RewriteRule (.*)\ (.*) $1%2520$2 then the resulting URL is http://servername/file520name.html; I've tried "%25" too, but then I only get a "5"; it just looks like the initial "%2" gets somewhat discarded. The questions: How can I build such a regexp to replace spaces with "%2520"? Is this the only way I can deal with this issue (other than a full search-and-replace which, as I said, can't be done), or do you have any better idea?

• How can I unregister a service with dns-sd?

  - by Roman

  I am trying to use "dns-sd" command line tool on my Windows 7 machine. I can already do something. For example I can register a service using "dns-sd -R ...". I also can browser (see) registered services using "dns-sd -B ...". What I still miss, is how to unregister a service. At the moment when I type "dns-sd -R ..." the dns-sd does not return me to the command prompt. To return to the command prompt I need to press Ctrl-C. And the service stays registered till I press Ctrl-C. What I want is to run "dns-sd -R ..." in the background regime and then I would like to have a possibility to unregister a service from the command line. One more thing which I do not understand yet is what "to look up a service" means. In my picture it should be sufficient to register a service, to see it and then to unregister it. But apparently I need to look up a service. What does it mean and why I need to do it? ADDED: As it is asked, I clarify. I refer to "dns-sd" command line tool which I use in Windows 7. I think this command is part of Bonjour software for Windows (from Apple). Well, I did not checked if I had this command before I installed Bonjour, but I assume I did not have it. So, my question is about this command.

• Win 2008 R2 terminal server and redirected printer queue security

  - by Ian

  I have a case where I need a non-priv account to be able to make a modification to the redirected printer. I know, its not advisable but we're not giving them access - changes will be made in code. So, following the docs (http://technet.microsoft.com/en-us/library/ee524015(WS.10).aspx) I modified the default security for new printer queues. This doesnt work though as windows doesn't seem to assign the privs you configure in the printer admin tool to redirected printer queues. As I test I added a non-priv test user to the default security tab in the printer admin tool (control panel - admin tools - printer admin. I assigned it all privs (its a test) and logged the user into the terminal server. The redirected printers duely appeared as usual. However if I open the printer properties - security tab, the user appears in the list of accounts/groups but the options I selected (all privs) are not set. Instead the user special privs box is marked and when I click on 'advanced options' and view them, there is nothing marked. So, something is clearing these options.... the question is, why and how can I convince it not to? Ian

• Is there an high quality natural text reader for the mac?

  - by Another Registered User

  I'm reading about 150 pages of text on screen, every day. I will have to read about 15.000 in the next upcoming months. No joke. Well, the problem is this: I suffer from a sort of attention deficit hyperactivity disorder which forces me to read every sentence up to 10 times until I really get it. Mac OS X Snow Leopard has a built-in text reader with the name "Alex". Although it is already pretty good quality, I know there are far better natural sounding voices out there. I have heard already voices that are absolutely amazing compared to Alex. They're so good, that you can't tell anymore the difference between a real person or a computer. Alex still has this "metal factor" in its voice, which makes my ears hurt after 8 hours of listening. The next problem with Alex is, that he never makes a break after a sentence. Also, it's not possible to think about a sentence and then continue reading. It's also not possible to have him repeat a sentence, without tedious text selection and shortcut usage. Actually, the best tool I can imagine would have the option to read a sentence and move on to the next one after pressing a special key, OR repeating the previously one after pressing a special key. That would help so much! And if that's even with one of those bell lab / AT&T / whatever super-natural voices, even better! But it would be already a great relief if there was just a better tool to control Alex. To let him make breaks after sentences or let him speak big chunks of text sentence-by-sentence with fine-grained control over repetition and moving on. Is there anything?

• Application to automate Windows software installation in a test lab

  - by Marc

  I have several test environments (hyper-V) which contain a variety of windows servers. Each machine needs periodically rolling back to a given snapshot and then re-installing with the latest version of our software to test. The software installs are quite complex MSI's with a fair few option screens. I know that the installs can be driven from the command line, passing in parameters to override the wizard options. At the simplest level I suppose I could just write a batch file to kick off each install with the required parameters, however the values that are passed in do need to change from time to time (and environment to environment) so a tool with a config file and simple GUI seems like a better idea. I think what makes it slightly more painful is the multiple environments. For example one environment might contain 4 servers and need a config file with all the server names, service endpoints etc. Another environment might be a 1-box install with all names and endpoints set to localhost. So, ideally I want to be able to store different setup configurations and use them to run all the required installers with the relevant settings against the relevant machines. Before I go off to write the thing, does anyone know of an existing, simple, free tool that will let me achieve this?

• User-friendly program to create editable & searchable pdf files, like tax & application forms and su

  - by Nick Gorbikoff

  Hello. Can somebody recommend user-friendly program that will create ( or convert from Excel & Word, or OpenOffice) editable pdf forms. You know like tax forms, that some of us filled out. Where you can create a form with predefined format and stationary, but let user edit/fill out fields. I need something user-friendly that a regular person can use. I'm NOT looking for a pdf library ( I already use wkhtmltopdf for generating pdfs programmaticaly). The reason is that we have about 400 documents ( internal expense forms, traing forms, etc) in .doc and .xls format that we want to convert to editable pdf ( so that people don't have to fill them out by hand). Coding 400 templates and then converting them using some lib or command line tool - is not my idea of fun, espsecially since those form change all the time. I'd like to just give HR and Quality department the tool, so that they can maintain those documents. I looked at everything listed on this page ( http://www.cogniview.com/convert-pdf-to-excel/post/pdf-editing-creation-50-open-sourcefree-alternatives-to-adobe-acrobat/ ), but can't find what I need. Thank you!!!
