  • Fast user switching is logging users off instead of switching users

    - by Nathan Osman
    I have a netbook running Windows 8.1 Pro that will no longer allow more than one user to be logged in at the same time. The steps necessary to reproduce this are as follows: The current user presses WIN to bring up the start screen. The user clicks his name in the corner and a list of other users appears. As soon as one of the other names is clicked, the user is unceremoniously logged off without any prompts. This behavior seems to have started some time after upgrading to Windows 8.1 from Windows 8. Before that point, everything worked fine and more than one user could be logged in at the same time. I've tried searching for others experiencing similar problems but this appears to be unique. System Details: CPU: Intel Atom N455 @ 1.66 GHz RAM: 1 GB OS: Windows 8.1 Pro w/ Media Center 32-bit

  • How many users are "many users"?

    - by kemp
    I need to find a solution for a website which is struggling under load. The site gets ~500 simultaneous connections during peak time, and counts around 42k hits per day. It's a wordpress based site bridged with a vbulletin forum with a lot of contents and a fairly complex structure which makes intensive use of the database. I already implemented code level full page caching (without this the server just crashes), and configured all other caching directives as well as combining css files and the like to limit http requests as much as possible. I need to understand if there is more that can be done via software or if the load is just too much for the server to handle and it needs to be upgraded, because the server goes down occasionally during peak times. Can't access the server now, but it's a dedicated CentOS machine (I think 4GB ram, can't say what CPU) running apache/mysql. So back to the main question: how can I know when the users are just too many?

  • Many users send using a single address, replies to that single address go to many users

    - by Keyslinger
    I work in an office with a Microsoft Exchange server for email. I would like to have the following workflow: John, Mary, or Sam send a message from Outlook on their respective computers. The customer receives the message from the address "[email protected]" The customer replies to the message from [email protected] and it is received by John, Mary, or Sam depending on who sent the message (if it was sent by John, the reply is sent to John, and so on). All users should also be able to send emails from their respective addresses as well (e.g. [email protected], etc.) Is this possible? If so, how can it be accomplished?

  • Implementing a Suspension or Penalty System for Users in ASP.NET MVC

    - by Maxim Z.
    I'm writing a site in ASP.NET MVC that will have user accounts. As the site will be oriented towards discussion, I think I need a system for admins to be able to moderate users, just like we have here, on Stack Overflow. I'd like to be able to put a user into a "suspension", so that they are able to log in to the site (at which point they are greeted with a message, such as, "Your account has been suspended until [DATE]"), but are unable to do the functions that users they would normally be able to do. What's the best way of implementing this? I was thinking of creating a "Suspended" role, but the thing is, I have a few different roles for normal users themselves, with different privileges. Have you ever designed a feature like this before? How should I do it? Thanks in advance.

  • Local Area Connection in Slacware 13

    - by asdasd
    I have windows xp and slackware 13 on one computer, and the ISP provided me a new modem. There was manual how to configure it, so i start the web browser and typed it's ip address 192.168.1.1 and the web interface of the modem appeared so i logged in, that was easy. But under slackware, i don't know how to enter in the modem config / web interface. I type in 192.168.1.1 but it's not working. Here's the output of ifconfig eth0 : eth0 Link encap:Ethernet HWaddr 00:a1:b0:01:18:28 inet addr:169.254.73.8 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 Memory:febff400-febff4ff How can i log in into the modem from linux, i.e. find it's assigned ip under slackware ? Thank you.

  • Sending mail to local address crashes web server (sendmail)

    - by deceze
    When trying to send mail automatically from a script at example.com via PHP's mail() to [email protected], the Apache server throws an Internal Error. I believe internally it is configured to use sendmail. The message gets dropped into ~/dead.letter and the general error log reads: [Wed May 12 11:26:45 2010] [error] [client xxx.xxx.xxx.xxx] malformed header from script. Bad header=/home/example/dead.letter... S: /home/example/www/test.php Trying any other address, not @example.com, works just fine. I have googled and serverfaulted for solutions, but they all require to edit configuration files in /etc/mail and similar system places, which is not an option, since this problem occurs on a shared host in which I only have access to ~/. Does anyone have a suggestion?

  • Synchronizing local and remote cache in distributed caching

    - by ltfishie
    With a distributed cache, a subset of the cache is kept locally while the rest is held remotely. In a get operation, if the entry is not available locally, the remote cache will be used and and the entry is added to local cache. In a put operation, both the local cache and remote cache are updated. Other nodes in the cluster also need to be notified to invalidate their local cache as well. What's a simplest way to achieve this if you implemented it yourself, assuming that nodes are not aware of each other. Edit My current implementation goes like this: Each cache entry contains a time stamp. Put operation will update local cache and remote cache Get operation will try local cache then remote cache A background thread on each node will check remote cache periodically for each entry in local cache. If the timestamp on remote is newer overwrite the local. If entry is not found in remote, delete it from local.

  • ASUS WL-500gP v2 network between two local machines

    - by Epsiloncool
    I have two windows XP machines in my home networks, connected with ASUS WL-500gp V2 which also used as internet router. Problem is: while I have both computers normally goes to internet (used DHCP, static routes is ON, routing table is empty, operation mode is Home Gateway). I see both computers listed on the Network Neighborhood on 1st computer (wired to router), can enter to my own computer, but can not enter to other. I see only one computer (2nd) on the Network Neighborhood on 2nd computer (connected thru Wi-Fi), can enter to itself, getting error when trying to enter 1st computer address in address line (like \My1stComp). What is the problem? I totally crazy founding problem about 3 months.

  • Maintain List of Active Users for Web

    - by Bryan Marble
    Problem Statement - Would like to know if particular web app user is active (i.e. logged in and using site) and be able to query for list of active users or determine a user's activity status. Constraints - Doesn't need to be exact (i.e. if a user was active within a certain timeframe, that's ok to say that they're active even if they've closed their browser). I feel like there should be a design pattern for this type of problem but haven't been able to find anything here or elsewhere on the web. Approaches I'm considering: Maintain a table that is updated any time a user performs an action (or some subset of actions). Would then query for users that have performed an action within some threshold of time. Try to monitor session information and maintain a table that lists logged in users and times out after a certain period of time. Some other more standard way of doing this? How would you approach this problem (again, from a design pattern perspective)? Thanks!

  • What steps/tools/apps are necessary to make local php development on a tablet viable?

    - by Tchalvak
    I do my php web development locally, as in, creating a local instance of a site and then coding it and then pushing code to servers via git/github. I'm considering getting an android tablet or ipad and a wireless keyboard for very mobile development, but I in no way want to go back to the bad old days of using ftp and syncing up code changes on a development server directly, that would be too much of a trade-off to interest me. Is there enough support for the stack to develop php websites locally on a tablet? Anyone had experience trying this sort of thing?

  • Unix Permissions issue with users belonging to the same group accessing a folder

    - by TK Kocheran
    I have a folder I'd really like to allow another user on this machine access to. I'm using mt-daapd to serve music to the network, so I'd like to enable the mt-daapd user to access my Music directory, /home/rfkrocktk/Music. The master user is rfkrocktk obviously. I've tried to set all of my permissions properly on the directory, but the mt-daapd user can't acces the files. I created a group called media-users and added both rfkrocktk and mt-daapd to it in order to give mt-daapd permission to simply read all of the files in that directory and subdirectories. If I run id on each of my users, here's what's displayed: $ id rfkrocktk > uid=1000(rfkrocktk) gid=1000(rfkrocktk) groups=1000(rfkrocktk),4(adm),20(dialout),24(cdrom),29(audio),46(plugdev),104(lpadmin),115(admin),120(sambashare),124(vboxusers),1001(jupiter),2002(media-users) $ id mt-daapd > uid=123(mt-daapd) gid=65534(nogroup) groups=65534(nogroup),2002(media-users) It definitely seems that both users are a part of the media-users group, so what could be going wrong? If I run ls -l on the actual Music directory to see its permissions, here's the output: drwxr-Sr-- 201 rfkrocktk media-users 12288 2011-01-13 12:26 Music If I run ls -l on the Music directory to get its children, here's the output: drwxr-Sr-- 3 rfkrocktk media-users 4096 2010-12-20 15:31 2DBoy drwxr-Sr-- 3 rfkrocktk media-users 4096 2010-05-25 12:50 ABBA drwxr-Sr-- 3 rfkrocktk media-users 4096 2009-12-28 15:19 Access Denied drwxr-Sr-- 10 rfkrocktk media-users 4096 2009-12-28 15:19 AC-DC drwxr-Sr-- 3 rfkrocktk media-users 4096 2009-12-28 15:19 Aerosmith drwxr-Sr-- 3 rfkrocktk media-users 4096 2010-06-04 10:45 A Flock of Seagulls drwxr-Sr-- 4 rfkrocktk media-users 4096 2010-05-28 18:13 Alestorm drwxr-Sr-- 3 rfkrocktk media-users 4096 2010-06-22 23:29 Amon Amarth drwxr-Sr-- 5 rfkrocktk media-users 4096 2009-12-28 15:19 Anberlin ... From this, it would seem that I should be able to access the folders from mt-daapd, but I can't. Running sudo -i -u mt-daapd ls -l /home/rfkrocktk/Music displays nothing, indicating to me that for whatever reason, mt-daapd doesn't have access to read the folder. What am I doing wrong?

  • php mysql database users connection handling

    - by aviv
    What is the best way to handle mysql database users connection in PHP? I have a web server running a PHP application on MySQL. I have created a database user for the application: dbuser1 with limited access - only for query, insert and update tables. No alter table. Now the question is, should i use the same dbuser1 widely in my scripts, so if there are 100 current people using my system and hence 100 scripts running parallel they all connect to the database with the same dbuser1? or should i create a few users and assign each script a different user or load-balance between the dbusers ?

  • How to use semantic markup and Google Places to assist in local search SEO?

    - by ElHaix
    In this article, adding additional localized markup is supposed to help your site's SEO. ie. <div itemscope itemtype="http://data-vocabulary.org/Organization"> <span itemprop="name">Search Engine People</span> <span itemprop="address" itemscope itemtype="http://data-vocabulary.org/Address"> <span itemprop="street-address">100 Westney Road South Unit 200, Building E</span> <span itemprop="locality">Ajax</span>, <span itemprop="region">ON</span> <span itemprop="country-name">Canada</span> <span itemprop="postal-code">L1S 7H3</span> </div> What about a site that contains valid localized results, where the actual business location is not relevant. For example, a site with valid local results from San Francisco, CA and Phoenix, AZ. Should these tags be added to the localized results, and has anyone got any experience with how much adding these tags have improved results? In terms of Google Places, however, they seem to ask for the business' actual physical location. Is there a way to use Google Places in the aforementioned example to assist in SEO?

  • Database users in the Oracle Utilities Application Framework

    - by Anthony Shorten
    I mentioned the product database users fleetingly in the last blog post and they deserve a better mention. This applies to all versions of the Oracle Utilities Application Framework. The Oracle Utilities Application Framework uses up to three users initially as part of the base operations of the product. The type of database supported (the framework supports Oracle, IBM DB2 and Microsoft SQL Server) dictates the number of users used and their permissions. For publishing brevity I will outline what is available for the Oracle database and, in summary, mention where it differs for the other database supported. For Oracle database customers we ship three distinct database users: Administration User (SPLADM or CISADM by default) - This is the database user that actually owns the schema. This user is not used by the product to do any DML (Data Manipulation Language) SQL other than that is necessary for maintenance of the database. This database user performs all the DCL (Data Control Language) and DDL (Data Definition Language) against the database. It is typically reserved for Database Administration use only. Product Read Write User (SPLUSER or CISUSER by default) - This is the database user used by the product itself to execute DML (Data Manipulation Language) statements against the schema owned by the Administration user. This user has the appropriate read and write permission to objects within the schema owned by the Administration user. For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. Product Read User (SPLREAD or CISREAD by default) - This is the database that has read only permission to the schema owned by the Administration user. It is used for reporting or any part of the product or interface that requires read permissions to the database (for example, products that have ConfigLab and Archiving use this user for remote access). For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. You may notice the words by default in the list above. The values supplied with the installer are the default and can be changed to what the site standard or implementation wants to use (as long as they conform to the standards supported by the underlying database). You can even create multiples of each within the same database and pointing to same schema. To manage the permissions for the users, there is a utility provided with the installation (oragensec (Oracle), db2gensec (DB2) or msqlgensec (SQL Server)) that generates the security definitions for the above users. That can be executed a number of times for each schema to give users appropriate permissions. For example, it is possible to define more than one read/write User to access the database. This is a common technique used by implementations to have a different user per access mode (to separate online and batch). In fact you can also allocate additional security (such as resource profiles in Oracle) to limit the impact of specific users at the database. To facilitate users and permissions, in Oracle for example, we create a CISREAD role (read only role) and a CISUSER role (read write role) that can be allocated to the appropriate database user. When the security permissions utility, oragensec in this case, is executed it uses the role to determine the permissions. To give you a case study, my underpowered laptop has multiple installations on it of multiple products but I have one database. I create a different schema for each product and each version (with my own naming convention to help me manage the databases). I create individual users on each schema and run oragensec to maintain the permissions for each appropriately. It works fine as long I have setup the userids appropriately. This means: Creating the users with the appropriate roles. I use the common CISUSER and CISREAD role across versions and across Oracle Utilities Application Framework products. Just remember to associate the CISUSER role with the database user you want to use for read/write operations and the CISREAD role with the user you wish to use for the read only operations. The role is treated as a tag to indicate the oragensec utility which appropriate permissions to assign to the user. The utilities for the other database types essentially do the same, obviously using the technology available within those databases. Run oragensec against the read write user and read only user against the appropriate administration user (I will abbreviate the user to ADM user). This ensures the right permissions are allocated to the right users for the right products. To help me there, I use the same prefix on the user name for the same product. For example, my Oracle Utilities Application Framework V4 environment has the administration user set to FW4ADM and the associated FW4USER and FW4READ as the users for the product to use. For my MWM environment I used MWMADM for the administration user and MWMUSER and MWMREAD for my associated users. You get the picture. When I run oragensec (once for each ADM user), I know what other users to associate with it. Remember to rerun oragensec against the users if I run upgrades, service packs or database based single fixes. This assures that the users are in synchronization with the ADM user. As a side note, for those who do not understand the difference between DML, DCL and DDL: DDL (Data Definition Language) - These are SQL statements that define the database schema and the structures within. SQL Statements such as CREATE and DROP are examples of DDL SQL statements. DCL (Data Control Language) - These are the SQL statements that define the database level permissions to DDL maintained objects within the database. SQL Statements such as GRANT and REVOKE are examples of DCL SQL statements. DML (Database Manipulation Language) - These are SQL statements that alter the data within the tables. SQL Statements such as SELECT, INSERT, UPDATE and DELETE are examples of DML SQL statements. Hope this has clarified the database user support. Remember in Oracle Utilities Application Framework V4 we enhanced this by also supporting CLIENT_IDENTIFIER to allow the database to still use the administration user for the main processing but make the database session more traceable.

  • Thread Local Memory for Scratch Memory.

    - by Hassan Syed
    I am using Protocol Buffers and OpensSSL to generate, HMACs and then CBC encrypt the two fields to obfuscate the session cookies -- similar Kerberos tokens. Protocol Buffers' API communicates with std::strings and has a buffer caching mechanism; I exploit the caching mechanism, for successive calls in the the same thread, by placing it in thread local memory; additionally the OpenSSL HMAC and EVP CTX's are also placed in the same thread local memory structure ( see this question for some detail on why I use thread local memory and the massive amount of speedup it enables even with a single thread). The generation and deserialization, "my algorithms", of these cookie strings uses intermediary void *s and std::strings and since Protocol Buffers has an internal memory retention mechanism I want these characteristics for "my algorithms". So how do I implement a common scratch memory ? I don't know much about the rdbuf of the std::string object. I would presumeably need to grow it to the lowest common size ever encountered during the execution of "my algorithms". Thoughts ?
