• ASP.Net Session Timing Out Rapidly

  - by Zac

  We have an ASP.Net 3.5 website running on Windows Server 2008 with IIS7. The session timeout period for this site is configured to be 20 minutes - however, it is currently lasting for between 40 and 50 seconds. After researching the problem we investigated several configuration values which could be involved in the timeout period but none of them are set to less than 20 minutes. The areas we look are as follows: web.config system.web/sessionState element (20 minutes). web.config system.web/authentication/forms element (not present, defaults to 30 minutes). Sites/{website}/ASP/Session Properties/Time-out (20 minutes). Application Pools/{appPool}/Advanced Settings/Process Model/Idle Time-out (20 minutes). We've also noted that the CPU is staying around 0% and that RAM usage is flat-lining around 1.07 GB (of 8 GB available) - so there is no performance-based reason for IIS to be recycling the Application Pool as far as we can tell. Are there any settings we've overlooked which could cause the session timeouts to be expiring so quickly? EDIT A couple of additional points: This is not occurring in development, only on the server. The session is not sliding (i.e. if we refresh the page a few times it still times out approximately 40 - 50 seconds after the session was created.

• Large scale file replication with an option to "unsubscribe" from a replicated file on a given machine

  - by Alexander Gladysh

  I have a 100+ GB files per day incoming on one machine. (File size is arbitrary and can be adjusted as needed.) I have several other machines that do some work on these files. I need to reliably deliver each incoming file to the worker machines. A worker machine should be able to free its HDD from a file once it is done working with it. It is preferable that a file would be uploaded to the worker only once and then processed in place, and then deleted, without copying somewhere else — to minimize already high HDD load. (Worker itself requires quite a bit of bandwidth.) Please advise a solution that is not based on Java. None of existing replication solutions that I've seen can do the "free HDD from the file once processed" stuff — but maybe I'm missing something... A preferable solution should work with files (from the POV of our business logic code), not require the business logic to connect to some queue or other. (Internally the solution may use whatever technology it needs to — except Java.)

• Is it better to always copy and delete, rather than move?

  - by nbolton

  Generally speaking, I find myself panicking when I realise that if I cancel a file move, it could cause the target or source to be incomplete. This question applies to Windows and Unix-based platforms. I can never remember exactly how the move command works in either case. For example, if you're moving a directory; does it copy the entire directory, then delete it after, or does it copy then delete each file individually? I always realise after typing something like, mv verybigdir dest that I really should have typed cp -R verybigdir dest && rm verybigdir (where the && operator only moves to the next command if the first was successful) -- or is this pointless? What happens exactly when I press Ctrl+C half way through a move? Likewise, what exactly happens on Windows when I press the cancel button? I can't count the number of times I've moved something (the last time was when using svn) and had two directories, with split contents. I guess the answer is difficult, because not all applications move groups of files in the same way.

• Trying to Set up SMTP Server on WIndows Server 2012

  - by datc

  I'm working on a website, and I need to test the functionality of sending email messages from ASP.NET, something like this: Dim msg As New MailMessage("email1", "email2") msg.Subject = "Subject"<br> msg.IsBodyHtml = True<br> msg.Body = "Click <a href='site'>here</a>." Dim client As SmtpClient = New SmtpClient() client.Host = "My-Server"<br> client.Port = 25<br> client.DeliveryMethod = SmtpDeliveryMethod.Network<br> client.Send(msg) This is running from a Windows 8 workstation. I've installed SMTP server on my Windows Server 2012 machine. The mail shows up in the mailroot/Queue folder and sits there, eventually getting deposited into Badmail. Now I have AT&T U-verse at home, and a few devices connected to the gateway, including let's call it "My-Server." When I run SmtpDiag from say, datc@... to [email protected] I get SOA serial number match passed, Local DNS (99-135-60-233.lightspeed.bcvloh.sbcglobal.net) & Remote DNS (hotmail.com) tests *not* passed, and ultimately, Connecting to the server failed. Error: 10060. Failed to submit mail to mx2.hotmail.com error. When I set My-Server's IP to static and equal to the external IP, 99.135.60.233, and again run SmtpDiag, I get SOA, Local DNS, and Remote DNS tests passed, but the same 10060 error. Same for yahoo.com, gmail.com, and so forth. Is it my ISP's job to fix this? Some PTR record missing somewhere? Is it at all possible to have a home-based SMTP server? All I want is to test my email code. Perhaps, my IP address is just not "trusted" somehow. Thanks.

• Log connections to program

  - by Zac

  Besides for using iptables to log incoming connections.. Is there a way to log established inbound connections to a service that you don't have the source to (suppose the service doesn't log stuff like this on its own)? What I'm wanting to do is gather some information based on who's connecting to be able to tell things like what times of the day the service is being used the most, where in the world the main user base is, etc. I am aware I can use netstat and just hook it up to a cron script, but that might not be accurate, since the script could only run as frequently as a minute. Here is what I am thinking right now: Write a program that constantly polls netstat, looking for established connections that didn't appear in the previous poll. This idea seems like such a waste of cpu time though, since there may not be a new connection.. Write a wrapper program that accepts inbound connections on whatever port the service runs on, but then I wouldn't know how to pass that connection along to the real service. Edit: Just occurred to me that this question might be better for stackoverflow, though I am not certain. Sorry if this is the wrong place.

• VNC Server that can be used from command line?

  - by jesusiniesta

  I'm looking for a replacement for a custom vnc server that we have been using in my company for a long time. I need a simple executable that can be run from command line by an IT Support software without the user noticing it (our application will warn the user, we don't want him to see we are using that VNC sever). I need it to support Windows and preferably also OSX. The only option I've found is UltraVNC, but I can't configure it from command line to accept loopback connections without authentication. We have already a whole VNC Viewer + VNC Repeater + Bouncers architecture, and the only missing piece is the VNC Server. Do you know any solution you could suggest me? I'm afraid I'll end up developing a new VNC server myself, may be based on an open source one. EDIT: When I said I don't want the user to notice this VNC server, I should have added that I don't want him even noticing the installation. So better if it can be installed silently or can be executed as a portable executalbe (for instance, ultravnc can be installed and ran as a service from command line, or simply executed quietly, with only a notification icon; its problem is that I can't run it without authentication).

• Best method to redirect internal DNS to external website?

  - by ProfessionalAmateur

  We host several web based applications outside of intranet. The URL's to these applications are long, complex and overall not user friendly. Ex: http://hostingsite:port/approot/folder/folder/login.aspx <-- (production) http://hostingsite:port22/approot/folder/folder/login.aspx <-- (dev) http://hostingsite:port33/approot/folder/folder/login.aspx <-- (test) I'd like to create an internal DNS entry to allow users to access these sites with ease. Ex: http://prod --> http://hostingsite:port/approot/folder/folder/login.aspx http://dev --> http://hostingsite:port22/approot/folder/folder/login.aspx I'm not familiar with the DNS process and setup, as far as I know a DNS can only be redirected to an IP, but not to subdomains for directory paths as described above? Is this a correct assumption? I am thinking for throwing up an internal webserver that will listen to the internal DNS entries and redirect to the external sites. http://prod --> [internal webserver] --> redirect --> http://hostingsite:port/approot/folder/folder/login.aspx Is there a better way to do this?

• What can be done to improve time synchronization on networks with sporadic internet access?

  - by anregen

  I'm looking for advice setting up time servers for a very non-typical network. I support many closed networks that have occasional access to the internet. A network would get access most days for a few hours, but would frequently go 1-3 weeks blacked-out. The computers/servers on this network are mostly *nix-based, but not all the same flavor. The entire network is mobile, so when it connects, it will have very different hops/latency to internet time servers. The servers on the closed network are powered-off frequently (at least daily). Right now, my gut tells me to use NTP (because I hate re-learning all the stuff that someone else already got working pretty well). But I have several issues, and am looking for someone with experience in this type of strange situation. I currently have no solution in place, I'm simply letting the internal clocks drift. This results in errors of ~600s in a majority of networks. I have seen mismatch worse than 10,000s. Is there something "better" than NTP in this situation? I know NTP likes to have very frequent, consistent access to servers that give nearly identical answers. I won't have that. How many internal NTP servers should I configure, so that during periods of internet blackout, I have internal time that is consistent within the closed network? There is no human access. No matter how large the mismatch, the server(s) must attempt to correct itself. Discrete steps are very bad. No matter how large the mismatch, the correction must be "slewed", not "stepped". I understand that this could take many hours to correct.

• windows: force user to use specific network adapter

  - by Chad

  I'm looking for a configuration/hack to force a particular application or all traffic from a particular user to use a specific NIC. I have an legacy client/server app that has a "security feature" that limits connections based on IP address. I'm trying to find a way to migrate this app to a terminal server environment. The simple solution is for the development team to update the code in the application, however in this case that's not an option. I was thinking I might be able to install VMware NIC's installed for each user on the terminal server and do some type of scripting to force that user account to use a specific NIC. Anybody have any ideas on this? EDIT 1: I think I have a hack to work around my specific problem, however I'd love to hear of a more elegant solution. I got lucky in that the software reads the server IP address out of a config file. So I'm going to have to make a config file for each user and make a customer programs files for each user. Then add a VMware NIC for each user and make each server IP address reside on a different subnet. That will force the traffic for a particular user to a particular IP address, however its really messy and all the VM NIC's will slow down the terminal server. I'll setup a proof of concept Monday and let the group know how it affects performance.

• What to do with old laptop screens?

  - by Lord Torgamus

  This question is inspired by another SU question I came across earlier today: What to do with old hard drives? It made me think about two long-dead laptops I have with perfectly good screens still inside. One is a Dell Inspiron 5100 and the other is an Averatec E1200, but responses need not be geared towards those particular models' screens. Rules, based heavily on the original question's: Objectives and suggestions to keep in mind when you post an answer : Should showcase your geekiness, be plain ol' fun, serve a social purpose or benefit the community. Your answer need not be limited to only one screen. For a really good answer, I'll go out and buy additional leftover screens. Your answer need not be limited to one project per screen. If additional accessories need be purchased, make sure they are common. Don't tell me to get a moon rock or something. The projects you suggested should serve a useful purpose; art is nice, but functional art is way better. Thanks in advance, folks. EDIT: Found another related question. Fun projects to do with an old 17" LCD monitor EDIT 2: I, for one, am enjoying the new outpouring of creativity here. Best fifty bucks... I mean, rep points... I ever spent. EDIT 3: That does it. At the end of the week, there was a tie for most votes between the accepted answer and the game platform answer. The game platform answer was cooler, but less reasonable as a project to actually do; in other words, it was more moon rocky. Unfortunately, I think fencepost had the best comment on the topic, which is that displays on their own have no good interface. Thanks for playing, everyone!

• Sendmail Configuration for Exchange Server

  - by user119720

  i need help for sendmail configuration in our linux machine. Here the things: I want to send email to outside by using our exchange server as the mail relay.But when sending the email through the server,it will response "user unknown".To make it worse, it will bounce back all the sent message to my localhost. I already tested our configuration by using external mail server such as gmail and yahoo,the configuration is working without any issue and the email can be sent to the recipient.Most of the configuration of my sendmail is based on here. authinfo file : AuthInfo:my_exchange_server "U:my_name" "I:my_email" "P:my_passwd" "M:PLAIN LOGIN" AuthInfo:my_exchange_server:587 "U:my_name" "I:my_email" "P:my_passwd" "M:PLAIN LOGIN" sendmail.mc : FEATURE(authinfo,hash /etc/mail/authinfo.db) define(`SMART_HOST', `my_exchange server')dnl define('RELAY_MAILER_ARGS', 'TCP $h 587') define('ESMTP_MAILER_ARGS', 'TCP $h 587') define('confCACERT_PATH', '/usr/share/ssl/certs') define('confCACET','/usr/share/ssl/certs/ca-bundle.crt') define('confSERVER_CERT','/usr/share/ssl/certs/sendmail.pem') define('confSERVER_KEY','/usr/share/ssl/certs/sendmail.pem') define('confAUTH_MECHANISMS', 'EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN') TRUST_AUTH_MECH('EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN') define('confAUTH_OPTIONS, 'A')dnl My first assumptions the problem occur is due to the authentication problem, as exchange server need encrypted authentication (DIGEST-MD5).I have already changed this in the authinfo file (from plain login to digest-md5 login) but still not working. I also can telnet our exchange server.So the port is not being blocked by firewall. Can someone help me out with this problems?I'm really at wits ends. Thanks.

• How to setup Joomla CMS as a backend for iPhone app

  - by srik

  I would like my iPhone app to get dynamic content off the net. This content should be managed using a CMS. I have gone ahead and installed Joomla on my server and will be using the Joomla web interface to create and manage content. I would now like the iPhone app to login to my server and fetch the content. I do not want the complete web pages for my iPhone app. Instead, I want the content in the form of XML or JSON or some serialized format so that I can use the data in a custom layout native to the app. So I am looking for 2 things in particular: 1. How to setup HTTP based authentication for my iPhone app to access data from my server. 2. How to access the content in a serialized format (XML, JSON etc) Are there plugins/extensions/components I can use to achieve the same. Any advice on how this can be achieved would be helpful. I am completely new to setting up/using CMS.

• Reverse proxy for mailserver (SMTP + HTTP for web client)

  - by ba

  I'm looking at doing some reverse proxy work for a mail server with corresponding web client. Both servers are running on the same machine, this is not a server with a high load. :) The solution I've discussed with friends is having the mail server/web client on our internal network. Then to put a reverse proxy on the DMZ to service both SMTP and web client HTTP-traffic to the mail server on the internal network. From what I understand this is the recommended secure solution? So far I've thought for the SMTP-proxy part of using postfix which will receive mail, do some spamhause and similar anti-spam measures and if it all checks out, send the mail to the mail server on the inside. The mail server on the inside will send all outgoing mail to the proxy which will then send it out on the Internet. For the web client I'm not sure exactly which software I should be running on the proxy machine, I've been thinking about using Squid -- but that's basically based on the fact that I know squid is a http proxy. The web client data will be sent out over SSL. Reading around some here on Serverfault I've seen other people using Apache with mod_proxy+mod_security for similar situations. Am I thinking correctly for this solution? What software would you guys use and with which modules? Thanks in advance for the help! :)

• VPS goes slow at more than 20 users online at the same time

  - by hachiari

  I have 512 MB VPS (brustable to 1GB) Somehow, the site goes slow when there are about 10 users, and becomes impossible to load at 20 users online at the same time. I wonder what could be the problem for this. The bandwidth connection of the VPS is 1Gbps. Here is some settings in my VPS: KeepAlive Off <IfModule prefork.c> StartServers 7 MinSpareServers 7 MaxSpareServers 10 ServerLimit 64 MaxClients 64 MaxRequestsPerChild 0 </IfModule> my.cnf settings - calculated Max Memory 300MB Output from UNIXBENCH INDEX VALUES TEST BASELINE RESULT INDEX Dhrystone 2 using register variables 376783.7 13429727.4 356.4 Double-Precision Whetstone 83.1 1137.5 136.9 Execl Throughput 188.3 1637.4 87.0 File Copy 1024 bufsize 2000 maxblocks 2672.0 148868.0 557.1 File Copy 256 bufsize 500 maxblocks 1077.0 79430.0 737.5 File Read 4096 bufsize 8000 maxblocks 15382.0 1410009.0 916.7 Pipe Throughput 111814.6 4419722.0 395.3 Pipe-based Context Switching 15448.6 561505.1 363.5 Process Creation 569.3 10272.7 180.4 Shell Scripts (8 concurrent) 44.8 514.3 114.8 System Call Overhead 114433.5 3537373.8 309.1 ========= FINAL SCORE 295.0 I am afraid that the VPS company limit the number of connection to the VPS... is it possible?

• Apache Named Virtual Hosts and HTTPS

  - by Freddie Witherden

  I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.

• Re-packaging commercial software into RPM packages

  - by gac

  The situation is this - I have a small CentOS 5 "cluster" (currently 7 machines, but potential for more) which run a commercially available software package that's distributed essentially in tarball format (it's actually a zip file with a mixture of Windows/Linux binaries and an installation shell script with no potential for automation). I'd like to re-package this somehow into an RPM package (ideally that I can throw onto a self-hosted yum repository) in order to keep these "cluster" machines both up to date and consistent. I could do 7 manual installations, but there's scope for error. As I understand it, I'll need to accomplish the following tasks: add a non-privileged user to the target system for running the daemon without unnecessary root privileges package the binary files themselves up from the final installation location on a separate build machine (probably under /opt/package for sanity's sake). No source is available. add a firewall hole in order for the end-users to be able to communicate with the "cluster" nodes add a cron task which can start the daemon on @reboot I'm coming up with plenty of good packaging resources so far, but all are based on the traditional method (i.e. if I were the vendor packaging up my source files), rather than re-packaging a ton of binary files from an already-installed instance of the application, which is the only option available to me. Anyone have any good resources they can share for achieving this goal? Thanks!

• Dead Linux server - need help and options

  - by Choi S.

  All, I have a Dell PE 1950 w/ 2 SATA drives in a software RAID1. OS is CentOS 5.5 (2.6.18.x). Starting this afternoon we received HW errors (something on the bus is bad, E171F) and the machine became unresponsive. We hard booted and it came back up for about 5 hours but then it happened again. I'm trying to figure out our options. Unfortunately we do not have similar hardware but I have a small desktop that I can use. I was contemplating putting one of the drives into the desktop and then starting it up. My goal was to then P2V it using Vmware converter but apparently the free v5.x doesn't support hot cloning/converting on a RAID volume, only the Enterprise 4.x version of Converter does. My questions are: 1.) Is putting a single drive out of a RAID1 pair into another piece of HW is safe? Based on my research and understanding it appears to be but would like confirmation. 2.) Is there any work around to the Vmware Converter not supporting RAID volumes during a hot clone/convert session? 3.) Are there other options I'm overlooking? Thanks in advance for reading and responding. --Choi S.

• Is it possible to map static IP to computer name instead of MAC address?

  - by xenon

  I have a number of computers with different hostnames connected to the network. They currently hold a static IP address based on their MAC address. In other words, the static IP address is mapped to their MAC address. This gives rise to a problem and that's when we swap the harddrive from one computer to another, the MAC address becomes different and the application we are running on the harddrive has problem getting the right static IP for it to work. We can't configure the IP address in the application all the time. And changing the static IP addresses to re-map to the computer's new MAC address can be quite a pain. Since all the computers have a unique computer name as their hostname, is it possible to configure such that when these computers grab IP addresses from the DHCP server, DHCP will learn about their hostname and assign the correct IP address? This is to say, the static IP is mapped to the computers' hostname instead of their MAC address. All the computers are running on Windows 7. Would this be possible? If so how should I go about do this?

• Cisco IOS ACL: Don't permit incoming connections just because they are from port 80

  - by cjavapro

  I am going much based on my memory and I may not be correct on all of this. On a Cisco 851 (IOS) that uses a BVI or a bridge-route (the servers on the inside are configured with static and public IP addresses). I would apply two access lists (both end with deny ip any any log) on FastEthernet4 (the WAN port). There would be one for FA4 in and another for FA4 out. FA4 out would have a line like access-list 110 permit 98.76.54.0 0.0.0.255 gt 1023 any eq http I think this means from 98.76.54.* with a from port of at least 1024 can connect to any other machine with a destination port 80. So, then I have to allow the response to the HTTP connection. FA4 in would have a line like access-list 120 permit any eq http 98.76.54.0 0.0.0.255 gt 1023 Now the problem with that is that anybody on the outside can set their from port to port 80 and then connect to any inside port that is at least 1024. How do we prevent this and require the incoming data to be a response to the outgoing data.

• nginx short urls for mediawiki

  - by William

  I am trying to do short URLs for a MediaWiki site. The wiki is in a subdirectory mydir (http://www.example.com/mywiki). I've already set up rewrites in /etc/nginx/sites-available so that example.com redirects to example.com/mywiki. Currently the URL is like http://www.example.com/mywiki/index.php?title=Main_Page. I want to clean up the url so that it looks like http://www.example.com/mywiki/Main_Page. I am having quite a bit of trouble doing this. I am not familiar with regular expressions or the syntax that the nginx config files use. This is what I currently have: server_name example.com www.example.com; location / { rewrite ^.+ /mywiki/ permanent; } location /wiki/ { rewrite ^/mywiki/([^?]*)(?:\?(.*))? /mywiki/index.php?title=$1&$2 last; } The second rewrite is obviously the one that's broken. It is based off of Page title -- nginx rewrite--root access in the MediaWiki documentation. When I try to load the site, the browser tells me I get infinite redirects. Does anyone who how I should go about fixing this issue? Or rather, what is the correct way to implement this, and what do all those symbols mean?

• Whats the best cloud backup solution for a small scale server environment?

  - by nbv4

  I have a server that runs a postgres database that contains about 200MB of data. Currently I have a cron job setup on my home computer which: ssh's into my server runs a remote script which makes a backup of the database scp's that dump over to my local hard drive for storage. Each dump is 20MiB. does this every six hours (one months of backups is roughly 2GiB) The problem with this setup is that if my local machine goes down for whatever reason, no backups will be made. Also, I can't have the cron run from the server, because I can't have it scp'd to my local machine from my server (firewalls and all that crap). My local machine is running Ubuntu 10.04, and my server is Ubuntu 9.10 server edition. I looked into Ubuntu One, but currently it's gui-only. I also looked into dropbox, but it's a pain in the ass to get setup in linux without gui support. Amazon S3 looks good but it's not free (yet dirt cheap). Is there any other alternative that I should look into? I'd prefer something where I can just have my script dump the database into a directory, and have the backup service 'watch' that folder and sync accordingly. I can maybe also have my local machine sync to the cloud backup so I have even more redundancy, plus easy access to my backups for use in testing. Edit: My server is a VPS, so what solution I end up using has to be 100% software based.

• Creating a Logical network diagram

  - by user273284

  Im a student and I have been assigned the task of creating a logical network diagram for the following scenario There are 2 buildings, the first is the head office and the second is the branch. The data centre is in the head office, it contains domain controller, mail server, file server and a web server. it provides wired and wireless access to the staff. the branch building is new and it does not have a network. The two buildings must be connected using a VPN connection. The branch building will not have any servers but just network devices that will provide the connectivity, the users in the branch building will be connected to the head office over the VPN. I had created a diagram based on this scenario, but my teacher rejected it saying that it does not follow Cisco hierarchical Model and the servers were not placed correctly in the diagram. I just wanted some help in this matter so that I Can create my network diagram correctly. If anyone could upload a picture of how the logical diagram should be for this scenario will be helpful, any other resources would also be great.

• Truecrypt files corrupted after moving PC into another case

  - by Dygerati

  I recently bought a new PC case and transferred all of my PC hardware into it. The only hardware modification was the addition of two identical ram modules. The entire process went smoothly, and everything worked and booted as before. The only side-effect I found when accessing one my of file-based hidden truecrypt volumes shortly there after. Some of the files in the volume - NOT all - seemed to be entirely corrupted. The directory and file names are garbled characters, but a few of the directories in the same volume appear and function normally. Also, all files in the non-hidden tc volume were still intact. Is this not weird? The only other real change I could think of would be that the hard drives were connected to different SATA ports on the mobo. I really don't know how the truecrypt encryption works well enough to know what could cause this...and the fact that not all the files were corrupted makes it more bizarre still. So, first off (and I'm not too hopeful on this point), would it be possible to restore these files? I had a backup of most, but not all of the files involved. Other than that I'm just curious how this happened and how I can prevent it next time. Thanks!

• How do I disable tablet gestures in windows 8?

  - by ???

  I'm using a Wacom Intuos4 and I have recently upgraded to Windows 8. I don't have a problem when using Photoshop however I occasionally draw on flash based online boards. The problem is, when I drag the pen in a direction repetitively (which is basically all I do when drawing) it's detected as a gesture, sometimes causing Chrome to go to the previous page (left drag) and making me lose the entire thing. Is there a way to disable these "gestures"? I believe this is not something caused by Windows 8 (or Charms) because I run Windows in English although it's not the initial language that Windows was installed in. I changed to English long after the installation. When Windows takes a move as a gesture, a small text pops up next to the cursor informing me about what I have just done and those pop ups are not even in English. I'm sorry for failing to be any more specific here but these gestures could be a feature of either Windows (unlikely), the tablet, Chrome or the computer itself. It's an Acer Aspire and it has one of those little stickers on it that specifies some of the features and one of them reads "Multi-Gesture" (referring to the touchpad, I guess). Could it be that this Multi-Gesture feature somehow decided to expand and apply for my tablet as well? If so, how do I disable it?
