• Strange Problem with Webservice and IIS

  - by Rene

  Hello there, I have a Problem which confuses me a little bit, resp. where I don't have any Idea about what it could be. The System I'm using is Windows Vista, IIS 7.0, VS2008, Windows Software Factory, Entity Framework, WCF. The Binding for all Webservices is wshttpbinding. I'm using a Webservice hosted in IIS. This Webservice uses/calls another Webservice (also installed in the IIS). If I use a client calling the first Webservice (which calls the second Webservice) it works fine for about 4-10 Times. And then (it is repeatable to get this Problem, but sometimes it happens after 4, sometimes after 10 Time, but it always will happen), the Service and the IIS gets stuck. Stuck means, that this Webservice isn't callable anymore and generates an timeout after 1 minute. Even increasing Timeout doesn't change anything. If i try to restart the IIS I get an timeout error. So the IIS is also "stuck" (it is not really stuck, but I can't restart it). Only if I kill the w3wp.exe IIS is restartable and the Webservice will work again (until i again call this service several times). The logfiles (i'm no expert in things like logging or where to find/enable such logs, so to say : i'm a newbie) like http-logging, Event Viewer or WCF-Message Logging don't show any hints upon the source of the problem. I don't have this problem when I'm using a Webservice which doesn't call another Service. Calling a Webservice is done by Service Reference (I'm using no Proxy-Classes), but I think this should be no Problem. I have no idea of what is happening, nor how to solve this Problem. Regards Rene

• What is actually happening to this cancelled HTTP request?

  - by Brian Schroth

  When a user takes a particular action on a page, an AJAX call is made to save their data. Unfortunately, this call is synchronous as they need to wait to see if the data is valid before being allowed to continue. Obviously, this eliminates a lot of the benefit of using Asynchronous Javascript And XML, but that's a subject for another post. That's the design I'm working with. The request is made using the dojo.xhrPost function, with a 60s timeout parameter, and the error handler redirects to an error page. What I am finding in testing is that in Firefox, if I initiate the ajax request and then press ESC, the page hangs waiting for a response, and then eventually after exactly 90s (not 60s, the function's timeout), the error handler will kick in and redirect to the error page. I expected this to happen, but either immediately as soon as the request was cancelled, or after 60s due to the timeout value being 60s. What I don't understand is why is it 90s? What is actually happening under the hood when the user cancels their request in Firefox, and how does it differ from IE, where everything works fine exactly the same as if the request had not been cancelled? Is the 90s related to any user-configurable browser settings?

• use proxy in python to fetch a webpage

  - by carmao

  I am trying to write a function in Python to use a public anonymous proxy and fetch a webpage, but I got a rather strange error. The code (I have Python 2.4): import urllib2 def get_source_html_proxy(url, pip, timeout): # timeout in seconds (maximum number of seconds willing for the code to wait in # case there is a proxy that is not working, then it gives up) proxy_handler = urllib2.ProxyHandler({'http': pip}) opener = urllib2.build_opener(proxy_handler) opener.addheaders = [('User-agent', 'Mozilla/5.0')] urllib2.install_opener(opener) req=urllib2.Request(url) sock=urllib2.urlopen(req) timp=0 # a counter that is going to measure the time until the result (webpage) is # returned while 1: data = sock.read(1024) timp=timp+1 if len(data) < 1024: break timpLimita=50000000 * timeout if timp==timpLimita: # 5 millions is about 1 second break if timp==timpLimita: print IPul + ": Connection is working, but the webpage is fetched in more than 50 seconds.

• VB.net httpwebrequest For loop hangs every 10 or so iterations

  - by user574632

  Hello, I am trying to loop through an array and perform an httpwebrequest in each iteration. The code seems to work, however it pauses for a while (eg alot longer than the set timeout. Tried setting that to 100 to check and it still pauses) after every 10 or so iterations, then carries on working. Here is what i have so far: For i As Integer = 0 To numberOfProxies - 1 Try 'create request to a proxyJudge php page using proxy Dim request As HttpWebRequest = HttpWebRequest.Create("http://www.pr0.net/deny/azenv.php") request.Proxy = New Net.WebProxy(proxies(i)) 'select the current proxie from the proxies array request.Timeout = 10000 'set timeout Dim response As HttpWebResponse = request.GetResponse() Dim sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If Catch ex As Exception 'MessageBox.Show(ex.ToString) used in testing UpdateListbox(ListBox4, proxies(i)) End Try completedProxyCheck += 1 lblTotalProxiesChecked.CustomInvoke(Sub(l) l.Text = completedProxyCheck) Next I have searched all over this site and via google, and most responses to this type of question say the response must be closed. I have tried a using block, eg: Using response As HttpWebResponse = request.GetResponse() Using sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If End Using End Using And it makes no difference (though i may have implemented it wrong) As you can tell im very new to VB or any OOP so its probably a simple problem but i cant work it out. Any suggestions or just tips on how to diagnose these types of problems would be really appreciated.

• Session hijacking prevention...how far will my script get me? additional prevention procedures?

  - by Yusaf Khaliq

  When the user logs in the current session vairables are set $_SESSION['user']['timeout'] = time(); $_SESSION['user']['ip'] = $_SERVER['REMOTE_ADDR']; $_SESSION['user']['agent'] = $_SERVER['HTTP_USER_AGENT']; In my common.php page (required on ALL php pages) i have used the below script, which resets a 15 minute timer each time the user is active furhtermore checks the IP address and checks the user_agent, if they do not match that as of when they first logged in/when the session was first set, the session is unset furthermore with inactivity of up to 15 minutes the session is also unset. ... is what i have done a good method for preventing session hijacking furthermore is it secure and or is it enough? If not what more can be done? if(!empty($_SESSION['user'])){ if ($_SESSION['user']['timeout'] + 15 * 60 < time()) { unset($_SESSION['user']); } else { $_SESSION['user']['timeout'] = time(); if($_SESSION['user']['ip'] != $_SERVER['REMOTE_ADDR']){ unset($_SESSION['user']); } if($_SESSION['user']['agent'] != $_SERVER['HTTP_USER_AGENT']){ unset($_SESSION['user']); } } }

• memcache is not storing data accross requests

  - by morpheous

  I am new to using memcache, so I may be doing something wrong. I have written a wrapper class around memcache. The wrapper class has only static methods, so is a quasi singleton. The class looks something like this: class myCache { private static $memcache = null; private static $initialized = false; public static function init() { if (self::$initialized) return; self::$memcache = new Memcache(); if (self::configure()) //connects to daemon { self::store('foo', 'bar'); } else throw ConnectionError('I barfed'); } public static function store($key, $data, $flag=MEMCACHE_COMPRESSED, $timeout=86400) { if (self::$memcache->get($key)!== false) return self::$memcache->replace($key, $data, $flag, $timeout); return self::$memcache->set($key, $data, $flag, $timeout); } public static function fetch($key) { return self::$memcache->get($key); } } //in my index.php file, I use the class like this require_once('myCache.php'); myCache::init(); echo 'Stored value is: '. myCache::fetch('foo'); The problem is that the myCache::init() method is being executed in full everytime a page is requested. I then remembered that static variables do not maintain state accross page requests. So I decided instead, to store the flag that indicates whether the server contains the start up data (for our purposes, the variable 'foo', with value 'bar') in memcache itself. Once the status flag is stored in memcache itself, It solves the problem of the initialisation data being loaded for every page request (which quite frankly, defeats the purpose of memcache). However, having solved that problem, when I come to fetch the data in memcache, it is empty. I dont understand whats going on. Can anyone clarify how I can store my data once and retrieve it accross page requests? BTW, (just to clarify), the get/set is working correctly, and if I allow memcache to load the initialisation data for each page request, (which is silly), then the data is available in memcache.

• How can I log any login operation in case of "Remember Me" option ?

  - by Space Cracker

  I have an asp.net login web form that have ( username textBox - password textBox ) plus Remember Me CheckBox option When user login i do the below code if (provider.ValidateUser(username, password)) { int timeOut = 0x13; DateTime expireDate = DateTime.Now.AddMinutes(19.0); if (rememberMeCheckBox.Checked) { timeOut = 0x80520; expireDate = DateTime.Now.AddYears(1); } FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(username, true, timeOut); string cookieValue = FormsAuthentication.Encrypt(ticket); HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, cookieValue); cookie.Expires = expireDate; HttpContext.Current.Response.Cookies.Add(cookie); AddForLogin(username); Response.Redirect("..."); } as in code after user is authenticated i log that he login in db by calling method AddForLogin(username); But if user choose remember me in login and then he try to go to site any time this login method isn't executed as it use cookies ... so i have many questions: 1- Is this the best way to log login operation or is there any other better ? 2- In my case how to log login operation in case of remember me chosen by user ?

• AIX specific socket programming query

  - by kumar_m_kiran

  Hi All, Question 1 From SUSE man pages, I get the below details for socket connect options If the initiating socket is connection-mode, then connect() shall attempt to establish a connection to the address specified by the address argument. If the connection cannot be established immediately and O_NONBLOCK is not set for the file descriptor for the socket, connect() shall block for up to an unspecified timeout interval until the connection is established. If the timeout interval expires before the connection is established, connect() shall fail and the connection attempt shall be aborted. If connect() is interrupted by a signal that is caught while blocked waiting to establish a connection, connect() shall fail and set errno to [EINTR], but the connection request shall not be aborted, and the connection shall be established asynchronously. Question : Is the above contents valid for AIX OS (especially the connection time-out, timed wait ...etc)?Because I do not see it in AIX man pages (5.1 and 5.3) Question 2 I have a client socket whose attributes are a. SO_RCVTIMEO ,SO_SNDTIMEO are set for 5 seconds. b. AF_INET and SOCK_STREAM. c. SO_LINGER with linger on and time is 5 seconds. d. SO_REUSEADDR is set. Note that the client socket is not O_NONBLOCK. Question : Now since O_NONBLOCK is not set and SO_RCVTIMEO and SO_SNDTIMEO is set for 5 seconds, does it mean a. connect in NON Blocking or Blocking? b. If blocking, is it timed blocking or "infinite" time blocking? c. If it is infinite, How do I establish a "connect" system call which is O_BLOCKING with timeout to t secs. Sorry if the questions are be very naive. Thanks in advance for your input.

• Connecting to database suddenly started throwing exception for my website

  - by Nirvan

  I have an MVC3 application hosted by third party hosting provider. The site has been running well for the past 3 months without any problems. Today suddenly the Application started throwing following Exception as recorded in my logs part of which is shown below. System.Data.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. --- System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The message is self explanatory and I first thought I should increase the connect timeout, but then the exception was still thrown suggesting the other part (Server Not Responding). I contacted my hosting provider and he said there was nothing wrong on his part. So I am stuck with a down website and don't know what to do. Any ideas why the provider is throwing the exception listed above. Also, is it possible for me to remotely connect to the database on the hosting server with limited authority. Any tools for that ? I don't have an exposure in database subject, except for application programming. regards, Nirvan

• Weird Rails database errors

  - by Jason Swett

  I've had some trouble getting my Rails app to connect to PostgreSQL so I decided to just say screw it and use SQLite for now. (I'm using the tutorial here: http://guides.rubyonrails.org/getting_started.html) I started a BRAND NEW, fresh Rails app from this tutorial. When I visit my app in the browser after deleting public/index.html, I get this the first time: Please install the pg adapter: `gem install activerecord-pg-adapter` (no such file to load -- active_record/connection_adapters/pg_adapter) That's odd to me because I'm not mentioning PostgreSQL anywhere. Here's my databases.yml: # SQLite version 3.x # gem install sqlite3-ruby (not necessary on OS X Leopard) development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: sqlite3 database: db/test.sqlite3 pool: 5 timeout: 5000 production: adapter: sqlite3 database: db/production.sqlite3 pool: 5 timeout: 5000 To make things more confusing, I only get that "pg adapter" error on the first load. For every subsequent page request, I get this error: ActiveRecord::ConnectionNotEstablished So even though I removed all mention of PostgreSQL, I'm still getting errors. What could be going on?

• How to drop/restart a client connection to a flaky socket server

  - by Steve Prior

  I've got Java code which makes requests via sockets from a server written in C++. The communication is simply that the java code writes a line for a request and the server then writes a line in response, but sometimes it seems that the server doesn't respond, so I've implemented an ExecutorService based timeout which tries to drop and restart the connection. To work with the connection I keep: Socket server; PrintWriter out; BufferedReader in; so setting up the connection is a matter of: server = new Socket(hostname, port); out = new PrintWriter(new OutputStreamWriter(server.getOutputStream())); in = new BufferedReader(new InputStreamReader(socket.getInputStream())); If it weren't for the timeout code the request/receive steps are simply: String request="some request"; out.println(request); out.flush(); String response = in.readLine(); When I received a timeout I was trying to close the connection with: in.close(); out.close(); socket.close(); but one of these closes seems to block and never return. Can anyone give me a clue why one of these would block and what would be the proper way to abandon the connection and not end up with resource leak issues?

• Perl: Value of response code in HTTP::Request

  - by lola

  Hi all, So, I am writing a code to get a document from the internet. The document size is around 200 KB. This is the code: !/usr/local/bin/perl -w use strict; use LWP::UserAgent; my $ua = LWP::UserAgent->new; my $url = "SOME URL"; my $req = HTTP::Request->new(GET => $url); my $res = $ua->request($req); if($res->is_success){ print $res->content ."\n"; } else{ print "Error: " . $res->status_line; } Now, the only problem is I can't mention what the URL is. However, the output is: "Error: 500 read timeout". When I checked the link externally, the data is being downloaded in under 5 seconds. I even changed the timeout to 1000s, but it still didn't work. How should I go about finding more information related to the response. The size of the file (around 200KB) is also not too great to warrant a read timeout. The server is also not a busy one, didn't give a problem whenever I checked the link on the browser. Thanks.

• AJAX Uploading - Not waiting for response before continuing

  - by waxical

  I'm using Blueimp's jQuery Uploader (very good it is too btw) and an S3 handler to upload files and then transfer them to S3 via the S3 API (from the PHP SDK). It works. The problem is, on large files (1GB) it can take anything up to a a few minutes to transfer (via create-object) onto S3. The PHP file that does this is hung-up until this process is complete. The problem is, the uploader (which utilises the jQuery Ajax method) seems to give up waiting and start again everytime. I have thought this was related to PHP INI 'max_input_time' or such, as it seemed to wait around 60 seconds, though this now appears to vary. I have upped the max_input_time in PHP INI and others related - but no further. I've also considered (the more likely) that JS, either in the script or the jQuery method has a timeout. The developer (blueimp) has said there's no such timeout in the front-end script, nor have I seen any and though 'timeout' is referenced in the jQuery Ajax method options, it seems to affect the entire time it uploads rather than the wait for a response - so that's not much use. Any help or guidance gratefully received.

• xcopy and timeouts

  - by acidzombie24

  Related to this question and this answer http://serverfault.com/questions/48839/backup-on-disc-using-truecrypt-corruption-problem/50829#50829 I want to copy the backup to my HD. However the timeout seems to be a problem. I see many single files then i see File creation error - Data error (cyclic redundancy check). and its currently trying to copy the next file. When i click my computer i see nothing and it also locks up for some seconds (30 maybe) So TrueCrypt is not a good solution if i must be able to copy files back from a volume with a corrupted sector? (answer in other thread please). Is there any way for me to change the timeout? I look here for some flags and didnt see any http://www.scriptlogic.com/support/CustomScripts/XCOPYCommandLineParameters.html

• straight to grub prompt on boot

  - by cheshirekow

  I am very lost. I did a fresh install of Ubuntu 10.04 on a laptop. First reboot was fine. I ran all the recommended upgrades, and now every time I start I get just a grub>_ prompt. No error message, just the prompt, and a little banner at the top saying grub's version and telling me that I have minimal bash style editing. I've tried: 1) Re-installing grub via sudo grub-install sda (There is only one disk with only two partitions, one primary, and one for swap) 2) Changed GRUB_HIDDEN_TIMEOUT=10 GRUB_TIMEOUT=30 GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=90" GRUB_CMDLINE_LINUX="rootdelay=90" in /etc/default/grub. No luck. I can boot with the following: grub> set root=(hd0,1) grub> probe (hd0,1) -u c00fadde-f7e8-45e7-a4da-0235605f756 grub> linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235605f756 rootdelay=90 grub> initrd /boot/initrd.img-2.6.32-21-generic grub> boot And then everything seems to be fine from there. From the grub prompt if I try configfile /boot/grub/grub.cfg The screen clears and I get another grub prompt. So, seriously, what could the problem be? edit: Full text of /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi } insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=640x480 insmod gfxterm insmod vbe if terminal_output gfxterm ; then true ; else # For backward compatibility with versions of terminal.mod that don't # understand terminal_output terminal gfxterm fi fi insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 set locale_dir=($root)/boot/grub/locale set lang=en insmod gettext if [ ${recordfail} = 1 ]; then set timeout=-1 else set timeout=30 fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_normal=white/black set menu_color_highlight=black/light-gray ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/10_linux ### menuentry 'Ubuntu, with Linux 2.6.32-21-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235c605f756 ro rootdelay=90 rootdelay=90 initrd /boot/initrd.img-2.6.32-21-generic } menuentry 'Ubuntu, with Linux 2.6.32-21-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 echo 'Loading Linux 2.6.32-21-generic ...' linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235c605f756 ro single rootdelay=90 echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-2.6.32-21-generic } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_memtest86+ ### menuentry "Memory test (memtest86+)" { insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 linux16 /boot/memtest86+.bin } menuentry "Memory test (memtest86+, serial console 115200)" { insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 linux16 /boot/memtest86+.bin console=ttyS0,115200n8 } ### END /etc/grub.d/20_memtest86+ ### ### BEGIN /etc/grub.d/30_os-prober ### if [ ${timeout} != -1 ]; then if sleep --verbose --interruptible 10 ; then set timeout=0 fi fi ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries.

• iSCSI connection timing out on ESX 3.5 against a NetApp storage appliance

  - by Jesse1973

  I get a timeout on iSCSI on different ESX hosts (3.5) at different times. It is puzzling, as both the ESX hosts as windows and other guests are experiencing timeouts. The iSCSI network is segregated on a private network. Here is an export of vmkiscsid.log from last night: 2010-02-10-12:30:38: iscsid: an InitiatorAlias= is required, but was not found in /etc/vmware/vmkiscsid/initiatorname.iscsi 2010-02-10-12:30:38: iscsid: LogLevel = 0 2010-02-10-12:30:38: iscsid: LogSync = 0 2010-02-10-12:30:42: iscsid: Login Success: iqn.1992-08.com.netapp:sn.101197719,default,192.168.73.2,3260,2001, 0x1 2010-02-10-12:30:42: iscsid: connection1:0 is operational now 2010-02-16-02:03:35: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-02:03:39: iscsid: connection1:0 is operational after recovery (2 attempts) 2010-02-16-04:02:27: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-04:02:32: iscsid: connection1:0 is operational after recovery (2 attempts) Should i edit the timeout value on the ESX host for iSCSI? This may work around the problem but will not solve it.

• WSUS data store error

  I have one upstream server and 17 downstream (configured as replicas). I'm getting this error in one of them and I'm stuck: "An error occurred with the server's data store".

• How can I expire non-active sessions on my Netscreen SSG140?

  - by David Mackintosh

  I have a Juniper Netscreen SSG-140. While experimenting with a VoIP service, I defined a custom policy that was to be used to permit the possible ports in use to be sent back to the VoIP server from systems connecting across the internet. Because I'd had problems in the past with VoIP systems getting broken when their UDP sessions were expired out faster than their keep-alives were generated, I set the timeout on this custom service to be 'never'. After much experimentation, I happened to notice that my session count on the firewall has grown from a couple thousand to over 36000. After discussion with the VoIP "expert", I set the timeout to be 30 minutes; however, all the sessions set up during the experimentation process are still there, more than 3 days later. Is there a way I can force these old sessions to get expired and removed from the session table, or am I looking at resetting my firewall? (Both firewalls, actually -- they are in a cluster.)

• How to change mouse pointer icon in Xfce Debian 7 Wheezy?

  - by kadaj

  I copied the cursor theme (oxy-neon or Oxygen Neon) to /usr/share/icons and from Applications Menu - Settings - Mouse, I am able to see the new theme. I clicked on it and the pointer doesn't change. However the text typing icon ('I'), busy icon, hand icon, and resize window icons got changed. The pointer icon remains the same, the black Adwaita. I removed the Adwaita folder from the icons folder, and still the mouse pointer doesn't change. Is the pointer theme specified elsewhere? I have no setting under home directory. I tried logging out, restart, restarting xfwm4, but nothing works. I just found that the icon pointer changes when the pointer is inside Firefox, but it's not consistent. It keeps changing when I click menu items. Very weird. Any idea how to fix this? This is the output of running: gsettings list-recursively org.gnome.desktop.interface : ~$ gsettings list-recursively org.gnome.desktop.interface org.gnome.desktop.interface automatic-mnemonics true org.gnome.desktop.interface buttons-have-icons false org.gnome.desktop.interface can-change-accels false org.gnome.desktop.interface clock-format '24h' org.gnome.desktop.interface clock-show-date false org.gnome.desktop.interface clock-show-seconds false org.gnome.desktop.interface cursor-blink true org.gnome.desktop.interface cursor-blink-time 1200 org.gnome.desktop.interface cursor-blink-timeout 10 org.gnome.desktop.interface cursor-size 24 org.gnome.desktop.interface cursor-theme 'Adwaita' org.gnome.desktop.interface document-font-name 'Sans 11' org.gnome.desktop.interface enable-animations true org.gnome.desktop.interface font-name 'Cantarell 11' org.gnome.desktop.interface gtk-color-palette 'black:white:gray50:red:purple:blue:light blue:green:yellow:orange:lavender:brown:goldenrod4:dodger blue:pink:light green:gray10:gray30:gray75:gray90' org.gnome.desktop.interface gtk-color-scheme '' org.gnome.desktop.interface gtk-im-module '' org.gnome.desktop.interface gtk-im-preedit-style 'callback' org.gnome.desktop.interface gtk-im-status-style 'callback' org.gnome.desktop.interface gtk-key-theme 'Default' org.gnome.desktop.interface gtk-theme 'Adwaita' org.gnome.desktop.interface gtk-timeout-initial 200 org.gnome.desktop.interface gtk-timeout-repeat 20 org.gnome.desktop.interface icon-theme 'gnome' org.gnome.desktop.interface menubar-accel 'F10' org.gnome.desktop.interface menubar-detachable false org.gnome.desktop.interface menus-have-icons false org.gnome.desktop.interface menus-have-tearoff false org.gnome.desktop.interface monospace-font-name 'Monospace 11' org.gnome.desktop.interface show-input-method-menu true org.gnome.desktop.interface show-unicode-menu true org.gnome.desktop.interface text-scaling-factor 1.0 org.gnome.desktop.interface toolbar-detachable false org.gnome.desktop.interface toolbar-icons-size 'large' org.gnome.desktop.interface toolbar-style 'both-horiz' org.gnome.desktop.interface toolkit-accessibility false ~$
