IIS permission configuration issue

- by Dan

Sorry the title of this question is a little ambiguous but I don't really have any idea where the issue lies - I'm seeking some clarification of the server error logs. Basically, I had a dedicated server running Windows 2003 and Plesk (v8 I think). Last week the server hardware failed and the entire thing had to be rebuilt from scratch. New hardware was put in, new operating system (Win2008), new Plesk installation (v9.5), new software (MSSQL etc) then all data ported over manually from old C and D drives to restore all 30 client sites. It was hell! All has been okay for a couple of days now but about an hour ago POP! Suddenly all sites went down giving a 500 error. Restarting all services eventually brought everything back online, but I'm now living in total fear. It can - and probably will - happen again. The guys on support gave me the following errors from the server log: The Template Persistent Cache initialization failed for Application Pool 'ASP.NET v4.0 Classic' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes.. The worker process for application pool 'domain1.com(domain)(2.0)(pool)' encountered an error 'Cannot read configuration file ' trying to read configuration data from file '\\?\C:\inetpub\temp\apppools\domain1.com(domain)(2.0)(pool).config', line number '0'. The data field contains the error code. The worker process for application pool 'PleskControlPanel' encountered an error 'Cannot read configuration file ' trying to read configuration data from file '\\?\C:\inetpub\temp\apppools\PleskControlPanel.config', line number '0'. The data field contains the error code. The support guys are so ambiguous about this and it scares me horribly. Can anyone positively identify the cause of this error which lead to all client website going offline? What can be done to prevent it from happening again? Any pointers would be very much appreciated! Thanks folks...

How to set up the jdbc driver to connect to hsqldb from libreoffice?

- by rumtscho

I am trying to "split" a LibreOffice .odb file into a HSQL database and an OpenOffice document containing forms and macros. I am trying to follow the instructions from this thread: Within a few minutes you can convert your embedded HSQLDB to a stand-alone HSQLDB which is just a very fine database engine. 1) Download and extract the current version from http://hsqldb.org/ and point the Java class path in ToolsOptionsJava to the new hsqldb.jar 2) Extract the database folder from your embedded database and rename the files data, properties, script to name.data name.properties, name.script where "name." is an arbitrary name prefix. 3) Connect a Base document to an existing JDBC database such as jdbc:hsqldb:file:/home/chenier/hsqldb/name;default_schema=true;shutdown=true;hsqldb.default_table_type=cached;get_column_name=false (again, "name" refers to your own file name prefix). This local single-user connection gives you much more than the embedded HSQLDB. 4) Copy queries, forms and reports from the old database over to the new one. The wizard presents me with a window expecting two inputs: a "Datasource URL" and a "JDBC driver class". As far as I can tell, the tutorial above only tells me what to put into the Datasource URL. As for the JDBC driver class, I have no idea what to write into this field. I tried the fully-qualified name of the Java class, org.hsqldb.jdbc.JDBCDriver as given in the HSQLDB documentation. When that failed, I tried the physical path /var/lib/hsqldb/lib/hsqldb.jar (although that should have been unnecessary, because first I pointed to this path as described under 1 and then restarted LibreOffice). In both cases, "Test class" failed with the message "The JDBC driver could not be loaded". OpenOffice's documentation doesn't say anything sensible about the field, it was something like "enter the JDBC driver in this box". Any ideas what I should enter there to get the connection working?

Diagnosing Logon Audit Failure event log entries

- by Scott Mitchell

I help a client manage a website that is run on a dedicated web server at a hosting company. Recently, we noticed that over the last two weeks there have been tens of thousands of Audit Failure entries in the Security Event Log with Task Category of Logon - these have been coming in about every two seconds, but interesting stopped altogether as of two days ago. In general, the event description looks like the following: An account failed to log on. Subject: Security ID: SYSTEM Account Name: ...The Hosting Account... Account Domain: ...The Domain... Logon ID: 0x3e7 Logon Type: 10 Account For Which Logon Failed: Security ID: NULL SID Account Name: david Account Domain: ...The Domain... Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x154c Caller Process Name: C:\Windows\System32\winlogon.exe Network Information: Workstation Name: ...The Domain... Source Network Address: 173.231.24.18 Source Port: 1605 The value in the Account Name field differs. Above you see "david" but there are ones with "john", "console", "sys", and even ones like "support83423" and whatnot. The Logon Type field indicates that the logon attempt was a remote interactive attempt via Terminal Services or Remote Desktop. My presumption is that these are some brute force attacks attempting to guess username/password combinations in order to log into our dedicated server. Are these presumptions correct? Are these types of attacks pretty common? Is there a way to help stop these types of attacks? We need to be able to access the desktop via Remote Desktop so simply turning off that service is not feasible. Thanks

How to rename network printer on Windows 7?

- by Adrian McCarthy

This question is similar to How do you rename a printer device in Windows 7 64 bit, except the answers there do not work, and I'll provide more information. This is a home network, not a domain. I have set up a Brother HL-5170DN. It is a network printer connected directly to an Ethernet hub. I can connect to it with Windows 7, but on Windows 7 it defaults to the name "binary_p1 on Brn37415f", which isn't very useful. And I cannot seem to change the name. I have it working with several Windows XP and Vista machines, and I can change the name on those machines. On Windows 7 Printer properties: I can see the "binary_p1" name on the General tab. I can select the text, but I cannot change it. The field is not grayed out, but I cannot type anything into it. On the Ports tab, all of the controls are grayed out (disabled). The selected Port is called "\\Brn_37415f\binary_p1", and it's described as "Client Side Rendering Provider" and the printer field says "binary_p1". On the Security tab, I can see that my account has "Manage this printer" permissions. If I choose Printer Server Properties, I can select the port and click Configure Port, but I get a dialog that says, "An error occurred during port configuration. This option is not supported." I have found many forums with people asking the same question without getting an answer. Update: No more bounties to offer, but I'm still looking for a solution to this problem.

Access 2007: How can I make this EXPRESSION less complex?

- by Mike

Access is telling me that my new expression is to complex. It used to work when we had 10 service levels, but now we have 19! Great! My expression is checking the COST of our services in the [PriceCharged] field and then assigning the appropriate HOURS [Servicelevel] when I perform a calculation to work out how much REVENUE each colleague has made when working for a client. The [EstimatedTime] field stores the actual hours each colleague has worked. [EstimatedTime]/[ServiceLevel]*[PriceCharged] Great. Below is the breakdown of my COST to HOURS expression. I've put them on different lines to make it easier to read - please do not be put off by the length of this post, it's all the same info in the end. Many thanks,Mike ServiceLevel: IIf([pricecharged]=100(COST),6(HOURS), IIf([pricecharged]=200 Or [pricecharged]=210,12.5, IIf([pricecharged]=300,19, IIf([pricecharged]=400 Or [pricecharged]=410,25, IIf([pricecharged]=500,31, IIf([pricecharged]=600,37.5, IIf([pricecharged]=700,43, IIf([pricecharged]=800 Or [pricecharged]=810,50, IIf([pricecharged]=900,56, IIf([pricecharged]=1000,62.5, IIf([pricecharged]=1100,69, IIf([pricecharged]=1200 Or [pricecharged]=1210,75, IIf([pricecharged]=1300 Or [pricecharged]=1310,100, IIf([pricecharged]=1400,125, IIf([pricecharged]=1500,150, IIf([pricecharged]=1600,175, IIf([pricecharged]=1700,200, IIf([pricecharged]=1800,225, IIf([pricecharged]=1900,250,0)))))))))))))))))))

Reusing slot numbers in Linux software RAID arrays

- by thkala

When a hard disk drive in one of my Linux machines failed, I took the opportunity to migrate from RAID5 to a 6-disk software RAID6 array. At the time of the migration I did not have all 6 drives - more specifically the fourth and fifth (slots 3 and 4) drives were already in use in the originating array, so I created the RAID6 array with a couple of missing devices. I now need to add those drives in those empty slots. Using mdadm --add does result in a proper RAID6 configuration, with one glitch - the new drives are placed in new slots, which results in this /proc/mdstat snippet: ... md0 : active raid6 sde1[7] sdd1[6] sda1[0] sdf1[5] sdc1[2] sdb1[1] 25185536 blocks super 1.0 level 6, 64k chunk, algorithm 2 [6/6] [UUUUUU] ... mdadm -E verifies that the actual slot numbers in the device superblocks are correct, yet the numbers shown in /proc/mdstat are still weird. I would like to fix this glitch, both to satisfy my inner perfectionist and to avoid any potential sources of future confusion in a crisis. Is there a way to specify which slot a new device should occupy in a RAID array? UPDATE: I have verified that the slot number persists in the component device superblock. For the version 1.0 superblocks that I am using that would be the dev_number field as defined in include/linux/raid/md_p.h of the Linux kernel source. I am now considering direct modification of said field to change the slot number - I don't suppose there is some standard way to manipulate the RAID superblock?

How to configure default text selection behavior in Windows XP, 7? (eg. mouse click selects entire word vs. mouse click inserts an active cursor)

- by Mouse of Fury

I find the mouse click behavior of Windows XP and Windows 7 annoying and intrusive. I don't remember Windows NT being quite this bad, or MacOS 7 - 10 which I used in the nineties. When I'm using a browser and I click on a text field - for example, the address bar, or a search box - the first thing which happens is the entire field is selected.Subsequent clicks seem to select parts of words, often deciding arbitrarily to exclude or include adjacent punctuation. The same in Excel and other apps, and when trying to rename files, so I'm assuming this behavior comes from a system-wide text handling routine. I frequently want to edit text, cut out or replace odd parts of the insides of words or chunks of sentences, and often find that to get a simple cursor to insert I have to click the mouse up to 4 times in succession. I've had to do a lot of this recently and it has been driving me insane. Is there a place at the system level where this can be configured? In a perfect world, I'd like a single click on a new text area to insert a cursor point, and a rapid double click to select the entire area. Words or text within the area could be selected by inserting a cursor, holding down the mouse button and dragging to the exact point where I want the selection to end - even if that's in the middle of a word. No, I don't need or want Windows to "smart select" a word or sentence for me. I've looked in the Mouse and Accessibility Options control panels (Windows XP). Haven't found anything even close. Thanks -

Ubuntu odd mouse and keyboard behavior when window gains inner focus

- by Scott

This morning on my Ubuntu 10.10 system when I open a window - for example, system-preferences-about me, if I click in to a field such as "work email", I can no longer close the window with the mouse! Clicking the X on the window will not work. Also, I loose the ability to click on anything else - clicking on the desktop, icons, menus, workspaces, etc. do not work. Even the effect when you hover over a folder on the desktop and that folder highlights - that stops until the window is closed. If I open this same screen but do not click in to a field, everything is fine - I can close the window with the X and everything else works fine. Same thing happens with several other windows I tried. Even calculator - I can open it, everything is fine until I click on a button in the calculator - then no ability to click on anything else. Have to Alt-F4 to close the window. The system is only about a week old from a fresh install (64 bit ubuntu - quad core amd machine). I uninstalled wine, turned off remote desktop/disabled in startup, also in startup disabled visual assistance, bluetooth, dropbox, klipper. Reboot, no difference. The only other thing non-standard I see in startup is nvidia. Using a logitec usb mouse, saitek usb keyboard. Was working fine yesterday. I can not think of anything I did / installed yesterday. I switched themse, then went to update manager and saw two x server / x org related updates and installed them, reboot and NOW IT IS FINE! However, then I re-enabled dropbox, klipper and remote desktop rebooted and the problem is back. Again I disabled and rebooted. Problem is still there!! So somehow I fixed it at least for a few minutes, but now it is back and I am out of ideas.

Mail-Merge on Steroids: Can Word 2003 do this?

- by richardtallent

I have a huge report to put together, made up of over 1,000 smaller, nearly-identical reports. Each report includes: General 1:1 information (basic mail-merge stuff) Lots of text, some of which may need to be disabled or have alternate text based on a boolean field. A few embedded images, preferably loaded via HTTP URL, but if they have to be on the a file system thing I can do that. (Filenames will be provided as a field in the data source.) Fortunately, all images are roughly the same size/shape. Several 1:m tables with a few fields apiece. The kicker is the master/child tables. I've seen examples for Word 2000 for doing this by left-joining the master and child table and using some IF/THEN logic to know whether to jump to the next master record. But in my case, I have several of these subtables, so that approach won't really work. So, can Word 2003 handle arbitrary master/child tables? If so, how? If not, I considered InfoPath, but I haven't used it before, and it seems to be made for data entry, not long formatted reports. I'm a software developer, so I could always hack something together with a massive VBA macro, or generating the report in HTML on the web server (where the data is coming from anyway). But I'm hoping Word will work without such gymnastics, since it will give the ultimate users of the report template better control over formatting and making minor changes.

Why does my ftp(e)s server fails like half of the time

- by user1092608

I have this discussion at work regarding our ftp server running via vsftpd. Initially, we have opted to serve ftpes instead of sftp because this seemed the most flexible and straightforward solution for our server to have secure file transmission. Afterwards, our ftp server seems to be a source of issues for our end users. Half of the time, users complain about not working ftp connections. I must say, i tested our FTP trough different infrastructures (=in the field, at random times at random places) and indeed, sometimes behind some configurations (=no idea how they are configured, because the 'field' testing), i recieve errors. Some of the are: Error: Failed to retrieve directory listing (filezilla) Furthermore, behind my basic home configuration, everything seems to be running fine. I (think I) did all the basic configuration checks (passive mode?, firewall for all ports?, ...) and can't seem to find the source. Being a bunch of techies at our small office, yet knowing nothing about infrastructure, some start suggesting that ftps protocol could be the source of issues. ("No, i only knew sftp so far" "Ftps is not widespread"). I, however, strongly doubt this hypothesis, since reading around on the www, asking questions on serverfault, everyone seems to deny this. So, as I would like to avoid reconfiguring, since this involves messing around in our SSH service, our virtual user setup and ftp service, i would need some advice on 1) what could be potentially the general cause? 2) do you have some general tips? 3) would you mind having a look at my configuration file? ----- General Settings ----- write_enable=YES dirmessage_enable=YES nopriv_user=ftpsecure ftpd_banner="Welcome to XXXX FTP!" hide_ids=YES hide_file=.* max_per_ip=10 max_clients=10 local_enable=YES local_umask=022 chroot_local_user=YES secure_chroot_dir=/usr/share/empty userlist_enable=NO userlist_deny=YES userlist_file=/etc/vsftp_deny_users guest_enable=YES guest_username=ftpvirtual virtual_use_local_privs=YES user_sub_token=$USER local_root=/srv/ftp/ftpvirtual/$USER anonymous_enable=NO syslog_enable=NO xferlog_enable=YES xferlog_file=/var/log/vsftpd_xfer.log connect_from_port_20=YES pam_service_name=vsftpd listen=YES listen_port=21 pasv_enable=YES pasv_min_port=30000 pasv_max_port=30030 pasv_address=foo ssl_enable=YES rsa_cert_file=/etc/vsftpd.pem rsa_private_key_file=/etc/vsftpd.pem force_local_data_ssl=YES force_local_logins_ssl=YES ssl_tlsv1=YES ssl_sslv2=YES ssl_sslv3=YES ssl_ciphers=HIGH anon_mkdir_write_enable=NO anon_root=/srv/ftp anon_upload_enable=NO idle_session_timeout=900 log_ftp_protocol=NO dsa_cert_file=/etc/vsftpd.pem Thanks

SMTP Server setting on Windows 2008 R2

- by user223298

I am very very new to this and just trying to configure SMTP virtual server. I have followed a few threads to get it all running, but the mails are not being delivered. What I have done so far - 1) Install SMTP server. 2) SMTP server Properties General Tab - IP address is set to 'All Unassigned'. Access Tab - Authentication is anonymous access. Everything else is left to Default settings. Delivery Tab - Outbound security is anonymous access. In Advance section, entered the domain name in the FQDN field, and localhost in Smart host field. 3) Created an Inbound Rule for SMTP service to allow connections to Port 25. When I try to telnet, everything works up until the point the mail has to be send. Now, the sender's domain is different to the receiver's domain. Not sure if settings have to be changed to allow that? I had set the Relay restrictions on SMTP server, but because I couldn't send the mails, I thought I might as well make it work without the relay first. The error I see while sending the mail is 451 Timeout waiting for client input. I used to get some other error before when I had Relay restrictions on. Can anyone please point me in the right direction? Please let me know if you need more information. Thanks.

Is there any any merit to routinely restore a linux system, even if unnecessary?

- by field_guy

I do fieldwork with a number of computers running ubuntu performing critical tasks doing fieldwork. The computers are similarly configured with slight variations. Since we've had some configuration issues in the past, my boss is pressing for us to take an image of the installation on each computer, and restore each computer to that image before they are to go into the field. My preferred solution would be to write a common script that checks to ensure that the configuration of the system is correct and that the system is operational. If the computer has been verified, isn't restoring it to that configuration redundant? And are there any inherent problems with doing so? My reluctance stems from the fact that our software and configuration is subject to change in the field, but these changes must be made across all the computers. That means that when a change is made, all the restoration images have to be updated as well. The differences in the configuration of each of the computers live in /etc. In the event that restoration is required, I would prefer to keep a single image containing everything that is common to all machines, and have a snapshot of each computer's /etc directory to be used for restoring the state of that particular machine. What's the better approach?

A "Trig" Calculating Class

- by Clinton Scott

I have been trying to create a gui that calculates trigonometric functions based off of the user's input. I have had success in the GUI part, but my class that I wrote to hold information using inheritance seems to be messed up, because when I run it gives an error saying: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - constructor ArcTrigCalcCon in class TrigCalc.ArcTrigCalcCon cannot be applied to given types; required: double,double,double,double,double,double found: java.lang.Double,java.lang.Double,java.lang.Double reason: actual and formal argument lists differ in length at TrigCalc.TrigCalcGUI.(TrigCalcGUI.java:31) at TrigCalc.TrigCalcGUI.main(TrigCalcGUI.java:87) Java Result: 1 and says it is the object causing the problem. Below Will be my code. First I will put up my inheritance class with cosecant secant and cotangent and then my original class with the original 3 trig functions: { public ArcTrigCalcCon(double s, double cs, double t, double csc, double sc, double ct) { // Inherit from the Trig Calc class super(s, cs, t); cosecant = 1/s; secant = 1/cs; cotangent = 1/t; } public void setCsc(double csc) { cosecant = csc; } public void setSec(double sc) { secant = sc; } public void setCot(double ct) { cotangent = ct; } } Here is the first Trigonometric class: public class TrigCalcCon { public double sine; public double cosine; public double tangent; public TrigCalcCon(double s, double cs, double t) { sine = s; cosine = cs; tangent = t; } public void setSin(double s) { sine = s; } public void setCos(double cs) { cosine = cs;

Script to create a table and fields in SQL wont work

- by Jacksta

Warning this is lenghty! attack if you knowledagble. well at least more then a newb beginner like me. This script uses three files as detailed below.

Thanks in advance!

"Error encountered while BER decoding" in Adobe Acrobat Pro X when applying timestamp

- by djechelon

I have a tedious problem with Acrobat Pro X 10.1.3.23: when I want to apply a timestamp to a document I always get that error. I have configured VeriSign TSA server http://timestamp.verisign.com/scripts/timstamp.dll and it returns that error. I have tried Comodo CA http://timestamp.comodoca.com/authenticode and Aruba https://servizi.arubapec.it/tsa/ngrequest.php but all three returned the same exact error. My PDFs are now signed without a certified timestamp and this is a problem for me. I'm obliged to sign documents and apply a certified timestamp at the same time. This seems to be a common error in Acrobat, but I found no solution to it. Can somebody help me?

How to set up spf records to send mail from google hosted apps to gmail addresses

- by Chris Adams

Hi there, I'm trying to work out why email I send from one domain I own is rejected by another that I own, and while I think it may be related to how I've setup spf records, I'm not sure what steps I need to take to fix it. Here's the error message I receive: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error.

Removing duplicate images (deduplication) - calculating "overlap" of images

- by jotango

Hello, I have a ton of product images on our file system. Our code removes 100% identical images (or does not allow them to be uploaded). However our sellers often upload items pictures which are very similar, but not exactly. They could have more whitespace, a worse quality (compression), a different size etc. Is there any way I can calculate the degree of overlap between two images, to flag ones for deletion? Kind of like a Levenshtein distance between two images... Any pointers would be very cool. Thanks!

Lock down a site using Forms Auth in IIS7 with Windows Auth

- by Josh

I have an ASP.NET MVC 1.0 application that uses Forms Authentication. We are using Windows Server 2008. I need to lock down the site so that only certain users (in AD Groups) can access the site. Unfortunately, though, when I set the site to not allow anon users and use windows authentication, due to the integration of the site and IIS, it shows the user as signed in as their domain account, instead of allowing them to sign in through Forms Auth. So, I need a mixed mode authentication. I need the site to be only accessible through windows auth, without anon users, but once you are in, it needs to use forms auth only. How would I go about doing this the right way?

How can I connect any USB device to my computer wirelessly?

- by daviesgeek

I am trying to connect the Canon 550D wirelessly to my computer so that I can control it from at a distance. It can connect normally via a USB cable, so I was wondering if there was a way to plug a dongle into the computer, and a dongle into the camera so the two can connect. I'm basically looking for a really long USB cord that will work over long distances (200+ feet). Another important factor is that I really would prefer not having use a power cord, rather just plugging in a dongle, as it will make the setup more mobile. Does anything like this exist? (I know that Cables Unlimited had something like what I wanted, but they went out of business last year)

Exchange 2003 Outlook Anywhere - Changed certificate, not working

- by JohnyD

I have a single Exchange 2003 installation which for the past 2 years has been set up for Outlook Anywhere access by means of a self-signed certificate. Just this past week I updated that certificate to a Go Daddy wildcard certificate to allow for use of our web services over https. I've updated the web listener on our ISA 2006 firewall and I can successfully use our services over https. However, my Outlook Anywhere access is now not functioning. I've installed the new wildcard certificate on my XP notebook into the Trusted Root Certificate Store but I keep getting prompted that the password is incorrect. To make things even more confusing I also have OWA set up and this works fine with the new certificate. Any ideas as to what I'm doing wrong?

Using SSL with Openfire

- by Dan

I'm having a rough time getting SSL configured properly on an Openfire install. Quite honestly, I just don't know what to do. It seems convoluted on the steps necessary to get a cert imported. Has anyone out there successfully done this? I'm running Openfire 3.6.4 on Server2003 R2. I have a signed UC cert which is ready to roll, I just don't know what to do with it. I've been through tons of tutorials on converting from .crt to .der to .pem, using openssl and java tools, but its only getting more confusing as I go.
