• MySQL can't access root account or reset with mysqladmin

  - by glumptious

  So if I type mysql -u root I'm supposedly logged in, however upon trying to create or access a database I get this lovely error: ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'test1'. I haven't the foggiest idea why after logging in as root it's trying access DB's as ''@'localhost' and it's driving me a bit crazy right now. Possibly related, when I try to set the root password I get the error mysqladmin: Can't turn off logging; error: 'Access denied; you need (at least one of) the SUPER privilege(s) for this operation'. I've tried removing mysql-server via running apt-get purge mysql-server and then reinstalling with no luck. This is running Ubuntu Server 12.10 64-bit and mysql is indeed running. --Edit-- I wonder if perhaps there is no root user. So I try to start MySQL with --skip-grant-tables and the create the root user but then I'm given this: ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement. Fun fun fun fun fun.

• Timestamp issue with localtime and mktime

  - by egiakoum1984

  Please see the code below: #include <iostream> #include <stdlib.h> #include <time.h> using namespace std; int main(void) { time_t current_time = 1270715952; cout << "Subscriber current timestamp:" << current_time << endl; tm* currentTm = localtime(&current_time); char tmp_str[256]; //2010-04-08T11:39:12 snprintf(tmp_str, sizeof(tmp_str), "%04d%02d%02d%02d%02d%02d.000", currentTm->tm_year+1900, currentTm->tm_mon+1, currentTm->tm_mday, currentTm->tm_hour, currentTm->tm_min, currentTm->tm_sec); cout << "Subscriber current date:" << tmp_str << endl; tm tmpDateScheduleFrom, tmpDateScheduleTo; memset(&tmpDateScheduleFrom, 0, sizeof(tm)); memset(&tmpDateScheduleTo, 0, sizeof(tm)); //2010-04-08T11:00 tmpDateScheduleFrom.tm_sec = 0; tmpDateScheduleFrom.tm_min = 0; tmpDateScheduleFrom.tm_hour = 11; tmpDateScheduleFrom.tm_mday = 8; tmpDateScheduleFrom.tm_mon = 3; tmpDateScheduleFrom.tm_year = 110; //2010-04-08T12:00 tmpDateScheduleTo.tm_sec = 0; tmpDateScheduleTo.tm_min = 0; tmpDateScheduleTo.tm_hour = 12; tmpDateScheduleTo.tm_mday = 8; tmpDateScheduleTo.tm_mon = 3; tmpDateScheduleTo.tm_year = 110; time_t localFrom = mktime(&tmpDateScheduleFrom); time_t localTo = mktime(&tmpDateScheduleTo); cout << "Subscriber current timestamp:" << current_time << endl; cout << "Subscriber localFrom:" << localFrom << endl; cout << "Subscriber localTo:" << localTo << endl; return 0; } The results are the following: Subscriber current timestamp:1270715952 Subscriber current date:20100408113912.000 Subscriber current timestamp:1270715952 Subscriber localFrom:1270717200 Subscriber localTo:1270720800 Why the current subscriber timestamp (subscriber date and time: 2010-04-08T11:39:12) is not between the range localFrom (timestamp of date/time: 2010-04-08T11:00:00) and LocalTo (timestamp of date/time: 2010-04-08T12:00:00)?

• 404 Error on a file that exists?

  - by Abs

  Hello all, A script makes a GET request to my URL like so: http://mydomain.com/cgi-bin/uu_ini_status_audios.pl?tmp_sid=b742be1d131c4d32237a9f1fcdca659e&rnd_id=0.2363453360320319 However, I get a 404 returned straight away: The requested URL /cgi-bin/uu_ini_status_audios.pl was not found on this server. But that script exists on my server, I can see the file! It has the correct permissions (I gave it a 777 to be sure). It is also owned by my apache user and its in the group apache. What am I missing?? Thanks for any help on this! Update I thought it would have been a htaccess (rewrite) but I don't think it is anymore. I tried putting a index.php file in there and try to access it via my URL but I can't even do that! I tried this: http://mydoamin.com/cgi-bin/index.php - same 404 error! I get this in myerror log: [Tue Sep 14 14:42:49 2010] [error] [client xx.xxx.xx.xxx] script not found or unable to stat: /var/www/vhosts/mydomain.com/cgi-bin Access_log file: xx.xxx.xx.xxx - - [14/Sep/2010:14:48:25 +0200] "GET /cgi-bin/index.php HTTP/1.1" 404 475 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.9) Gecko/20100824 Firefox/3.6.9 (.NET CLR 3.5.30729)" Update 2 My htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^blog/ - [L] RewriteCond %{HTTP_HOST} ^www\.mydomain\.com$ [NC] RewriteRule ^(.*)$ http://mydomain.com/$1 [R=301,L] RewriteRule ^search/(.*)/(.*)/(.*)/(.*) /search.php?searchfor=$1&sortby=$2&page=$3&searchterm=$4 RewriteRule ^confirmemail/(.*) /confirmemail.php?code=$1 RewriteRule ^resetpassword/(.*) /resetpassword.php?code=$1 RewriteRule ^resendconfirmation/(.*) /resendconfirmation.php?userid=$1 RewriteRule ^categories/ /categories.php RewriteRule ^([-_~*a-zA-Z0-9]+)(\/)?$ /memberprofile.php?username=$1 RewriteRule ^browse/audios/(.*)/(.*)/(.*)/(.*) /audios.php?sortby=$1&filter=$2&page=$3&title=$4 RewriteRule ^browse/categories/audios/(.*)/(.*)/(.*)/(.*) /categoryaudios.php?sortby=$1&filter=$2&page=$3&title=$4 RewriteRule ^audios/(.*)/(.*) /playaudio.php?audioid=$1&title=$2 RewriteRule ^download/audio/(.*)/(.*) /downloadaudio.php?AUDIOID=$1&title=$2 RewriteRule ^members/audios/(.*)/(.*) /memberaudios.php?pid=$1&username=$2 RewriteRule ^syndicate/audios/(.*)/(.*) /syndicateaudios.php?filter=$1&title=$2 </IfModule> Update 3 [root@smydomain ~]# ls -la /var/www/vhosts/mydoamin.com/httpdocs/cgi-bin/ total 60 drwxr-xr-x 3 apache root 4096 Sep 14 14:37 . drwxr-x--- 20 som psaserv 4096 Sep 14 14:40 .. drwxr-xr-x 2 apache root 4096 Sep 7 03:01 configs -rwxrwxrwx 1 apache root 4 Sep 14 14:37 index.php -rwxrwxrwx 1 apache apache 6520 Sep 7 03:01 uu_ini_status_audios.pl -rwxr-xr-x 1 apache root 3215 Sep 7 03:01 uu_lib_audios.pl -rwxr-xr-x 1 apache root 30249 Sep 7 03:01 uu_upload_audios.pl

• What is the meaning of these BIND log messages?

  - by javano

  Please clarify for me the meaning of the following BIND messages in syslog, these are from a DNS resolver. Whilst I think I understand them, I don't know what all four mean, so I think it's best if someone will clarify for me: 1.

• SQL IO and SAN troubles

  - by James

  We are running two servers with identical software setup but different hardware. The first one is a VM on VMWare on a normal tower server with dual core xeons, 16 GB RAM and a 7200 RPM drive. The second one is a VM on XenServer on a powerful brand new rack server, with 4 core xeons and shared storage. We are running Dynamics AX 2012 and SQL Server 2008 R2. When I insert 15 000 records into a table on the slow tower server (as a test), it does so in 13 seconds. On the fast server it takes 33 seconds. I re-ran these tests several times with the same results. I have a feeling it is some sort of IO bottleneck, so I ran SQLIO on both. Here are the results for the slow tower server: C:\Program Files (x86)\SQLIO>test.bat C:\Program Files (x86)\SQLIO>sqlio -kW -t8 -s120 -o8 -frandom -b8 -BH -LS C:\Tes tFile.dat sqlio v1.5.SG using

However, the 64 write test is incredibly slow on the rack server. (68 mb/sec on the slow tower vs 21 mb/s on the rack). The read speed for 64k also seems slow. Is this enough to say there is some sort of bottleneck with the shared storage? I need to know if I can take this evidence and say we need to launch an investigation into this. Any help is appreciated.

• PDAnet on Android IP on PC is not public IP. Where does the NAT take place, PDAnet or Verizon?

  - by lcbrevard

  When using PDAnet on a PC (Win7 ultimate) to USB tether a Motorola Droid on Verizon 3G the IP address of the PC appears to be public - 64.245.171.115 (64-245-171-115.pools.spcsdns.net) - but connections show as coming from another public IP - 97.14.69.212 (212-sub-97.14.69.myvzw.com). Someone is performing Network Address Translation - either PDAnet or within the Verizon 3G network. Can someone tell me who is doing the NAT? Is it PDAnet or is it at Verizon? Is there any possibility of setting up port forwarding, such that connections to the public IP 97.14.69.212 (212-sub-97.14.69.myvzw.com) are forward to the PC? We are testing a network protocol that requires either a true public IP or forwarding a range of ports from the public Internet to the system on which the software runs (actually Linux hosted by VMware Player or Workstation on a PC running Windows).

• SMTP hacked by spammer using base64 encoding to authenticate

  - by Throlkim

  Over the past day we've detected someone from China using our server to send spam email. It's very likely that he's using a weak username/password to access our SMTP server, but the problem is that he appears to be using base64 encoding to prevent us from finding out which account he's using. Here's an example from the maillog: May 5 05:52:15 195396-app3 smtp_auth: SMTP connect from (null)@193.14.55.59.broad.gz.jx.dynamic.163data.com.cn [59.55.14.193] May 5 05:52:15 195396-app3 smtp_auth: smtp_auth: SMTP user info : logged in from (null)@193.14.55.59.broad.gz.jx.dynamic.163data.com.cn [59.55.14.193] Is there any way to detect which account it is that he's using?

• Why would memcached refuse to store data with some keys ?

  - by Pierre

  Hello, I use the memcache extension for python, and I have a very strange problem. Memcached refuses to store the exact same data with some keys, and succeeds in caching some others. >>> conn.set('138b9c95d693760840aab85ee5591d2', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d3', 'test'); 0 >>> conn.set('138b9c95d693760840aab85ee5591d4', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d5', 'test'); 0 >>> conn.set('138b9c95d693760840aab85ee5591d6', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d7', 'test'); 0 >>> conn.set('138b9c95d693760840aab85ee5591d8', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d9', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591e0', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591e1', 'test'); True I don't really understand. I should add that I use the version 1.40 of the memcache module with memcached 1.2.8 running on Ubuntu Server 9.10. I restarted the memcached daemon, same result, with the same keys. Thanks. Update: I upgraded memcached to version 1.4.2, packaged on lucid repos, with the exact same result.

I'm currently testing on the same machine but eventually the celery worker should run on a remote machine. django uses the following settings: BROKER_HOST = "127.0.0.1" BROKER_PORT = 5672 BROKER_VHOST = "/my_vhost" BROKER_USER = "celery" BROKER_PASSWORD = "celery" I can also see my task queued in http://localhost:55672/#/queues the celery daemon uses the following configuration (celeryconfig.py): BROKER_HOST = "127.0.0.1" BROKER_PORT = 5672 BROKER_USER = "celery" BROKER_PASSWORD = "celery" BROKER_VHOST = "/my_vhost" CELERY_RESULT_BACKEND = "amqp" import os import sys sys.path.append(os.getcwd()) CELERY_IMPORTS = ("tasks", ) running celeryd -l info works well and now I want to run it as a service. I've followed the instructions from http://ask.github.com/celery/cookbook/daemonizing.html and now I'm trying to run it using: sudo /etc/init.d/celeryd start But the message is not being consumed, no error in the celery log either. /etc/default/celeryd CELERYD_NODES="w1" CELERYD_CHDIR="/path/to/django/project" CELERYD_OPTS="--time-limit=300 --concurrency=1" CELERY_CONFIG_MODULE="celeryconfig" # %n will be replaced with the nodename. CELERYD_LOG_FILE="/var/log/celery/%n.log" CELERYD_PID_FILE="/var/run/celery/%n.pid" # Workers should run as an unprivileged user. CELERYD_USER="celery" CELERYD_GROUP="celery" I've also created user celery in Ubuntu not sure if its necessary. Any help will be appreciated, Thanks, Guy

• playing flash movies in lightbox

  - by Cptcecil

  I'm using JQuery and Prototype in this web application that I'm developing. I'm looking for a way to use Lightbox v2.04 by Lokesh Dhakar to play flash movies. If its not possible using the Lightbox v2.04 then what other ways can I accomplish the shadowing overlayed flash video pop-up with jquery and/or Prototype? The reason I'm set on v2.04 is because I'm using it already as an image gallery. I'm using flv type flash files if that helps.

• Can't create new "enterprise" project in netbeans

  - by Danny

  I'm running netbeans 6.7.1 on Ubuntu Karmic. On the services tab I added a new glassfish v3 prelude server, I installed it to my home directory using the download button. I started the server and opened localhost:4848 to verify I can get into the admin panel. Then I did file-new projct and created a new java web-web application. On the configuration step of the wizard it preselected glassfish v3 prelude and java ee 5. I accepted and did a test run. I ran the project just fine. So now I did file-new projecct and attempted to create a Java EE-ejb module. When I arrive to the server configuration stage of the wizard, it doesn't show any servers on the server dropdown list (so it's empty), it also doesn't see any version of java on the "java ee version" dropdown list. This also happens for the other "Java EE" project types. I can't seem to get my head around why I can make a new web application but not an ejb module. Can anyone provide any insight to why it might not be seeing that I have java or glassfish installed when I try to make a new java ee project but I see it when I try to make a java web project?

• How to install ia32-libs on Wheezy?

  I have seen a couple of questions on ServerFault relating to installing ia32-libs on a 64bit machine but the solutions aren't working for me (I don't think any of these questions where for Wheezy specifically I'm not sure how to proceed); root@server:/home/# apt-get install -f ia32-libs Reading package lists...

• mod_rpaf problems with Nginx front, Apache back-end after Ubuntu upgrade

  - by Kenn

  I'm running an Nginx front-end for static files, and proxying to an Apache backend for PHP and Passenger, using Apache's mod_rpaf to set the correct remote IP address on the backend. Everything worked fine until I upgraded to Ubuntu 12.04 (Precise). Now Apache reports all connections coming from 127.0.0.1. Here's the relevant configuration. Nothing here changed with the upgrade. Nginx: proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; mod_rpaf: <IfModule mod_rpaf.c> RPAFenable On RPAFsethostname On RPAFproxy_ips 127.0.0.1 ::1 RPAFheader X-Forwarded-For </IfModule> I'm using %{X-Forwarded-For}i in my Apache LogFormat directive and the access logs are showing the correct remote address, so I know Nginx is passing the address along properly. In a phpinfo() test, HTTP_X_FORWARDED_FOR is showing the correct remote address, but REMOTE_ADDR is 127.0.0.1. This is reflected in PHP applications as well, such as WordPress comments. I've tried switching Nginx and mod_rpaf to X-Real-IP with no effect. Did something change that I missed? Relevant version info, everything installed from the Ubuntu repository: Nginx 1.1.19 Apache 2.2.22 mod_rpaf 0.6

• Strange mysql problem moving website from Ubuntu server to Mac server

  - by evan

  I'm moving a website (php/mysql) from an Ubuntu server to a OSX 10.6 server. I've set up apache to run php scripts and setup the newest version of mysql on the mac. I just copied all of the php files and dumped/imported all of the mysql databases (including the mysql users database). When I visit the page being served on the Mac the page is able to connect to the database, but not query. Specifically this function mysql_error() is returning this error message NO SUCH FILE OR DIRECTORY The reason it's strange is that I'm able to change the php connection strings for mysql on the Ubuntu server so that it points to the Mac server and the page works correctly (so it seems mysql is correctly set up on the mac and definitely contains all of the users and tables it should). Thinking it was something to do with file permissions on the mac, I've changed all of the files 755 and it hasn't helped. Any ideas? Thanks!! UPDATE: I've found this error which I'm relatively certain is related to this problem in /var/log/apache2/error_log PHP Warning: mysql_query(): A link to the server could not be established

• Getting Started in SuSE as an Ubuntu User

  - by Subhamoy Sengupta

  I am not a Linux newbie, but haven't touched SuSE in a very very long time (last time I tried it, it was SuSE 7!). Finally now I felt like giving it a try, and many things seem strange or unnecessarily complex. I have a series of questions. How do I ensure that my packages are uptodate? It sounds silly, but I tried the obvious methods already. I have disabled the default repositories that show up when you do zypper lr, and added Tumbleweed and packman repositories (Essentials, Multimedia, Extra). Then I did a sudo zypper ref --force and then sudo zypper dup, and it tells me many dependencies are not met. I have already added solder.allowVendorChange=true to /etc/zypp/zypp.conf, so it should not care which repository the latest versions are in, and just upgrade to it. Even when I chose to skip the packages with unmet dependencies, and seemed like quite a bit happened in the background, I opened Firefox afterwards and the version was 7! I am guessing things did not go as expected. But of course this is not a problem with SuSE, but I am not understanding the system right. How do I do it right? When I start typing arguments of a command, for example sudo zypper install, when I type sudo zypper ins and keep hitting TAB, nothing happens! It always worked in Ubuntu and I feel very uneasy with this. Is this how SuSE is supposed to be? When I try to install something, and I start writing its name, even though the package exists and I am sure of it, hitting TAB does not autocomplete it. This is also quite inconvenient. Why is it not happening? There are many things in SuSE that are really great, and I think I will stay with it and not go back to Ubuntu once I settle these very rudimentary issues. But right now they are giving me a lot of grief! Please help!

• PDAnet on Android IP on PC is not public IP. Where does the NAT take place, PDAnet or Verizon?

  - by lcbrevard

  When using PDAnet on a PC (Win7 ultimate) to USB tether a Motorola Droid on Verizon 3G the IP address of the PC appears to be public - 64.245.171.115 (64-245-171-115.pools.spcsdns.net) - but connections show as coming from another public IP - 97.14.69.212 (212-sub-97.14.69.myvzw.com). Someone is performing Network Address Translation - either PDAnet or within the Verizon 3G network. Can someone tell me who is doing the NAT? Is it PDAnet or is it at Verizon? Is there any possibility of setting up port forwarding, such that connections to the public IP 97.14.69.212 (212-sub-97.14.69.myvzw.com) are forward to the PC? We are testing a network protocol that requires either a true public IP or forwarding a range of ports from the public Internet to the system on which the software runs (actually Linux hosted by VMware Player or Workstation on a PC running Windows).

• .htaccess issue on Apache Web Server in Ubuntu VM

  - by Neon Flash

  I just installed Apache Web Server on Ubuntu 11.04 in VMWare Workstation. I created a basic HTML page, named it index.html and placed it in /var/www directory (document root). I am able to access this web page from my Host OS (Windows 7), by pointing the browser to: http://192.168.2.2/index.html where, 192.168.2.2 is the IP Address of the Ubuntu VM. Next, to test various configurations of .htaccess files, I created a new directory in /var/www called, members. Inside this directory, I created and placed a .htaccess file with the following configuration: AuthUserFile /www/Neon/auth/.htpasswd AuthName "neon's home" AuthType Basic require valid-user IndexIgnore */* I created a directory path like /var/www/Neon/auth/ and then placed a .htpasswd file inside it. To place the username and hash inside the .htpasswd file: I created a username "neon" and calculated the DES hash of a password and placed it inside .htpasswd file in format: username:hash Now, when I try to access the web page: http://192.168.2.2/members/ It does not prompt me to enter the username and password with a popup box. Instead it just displays the index.html which is placed inside members directory. I would like to get this configuration working :)

• How To Boot with "mem=1024m" Argument using GRUB - Ubuntu 10.04

  - by nicorellius

  I am still working on this question. This new one is a different question so I thought it would be good to post a new question. Is this the proper protocol or should I have just edited the other question? I'm running Ubuntu 10.04 with the kernel 2.6.32-22-generic on a Toshiba Satellite laptop. When I enter the GRUB menu (I have Ubuntu 9.10 installed as well), I can choose which kernel to boot. I use scroll down to the one I want and press "e" and I expect to be able to enter mem=1024m and force the kernel to use this much memory. But when I run cat /proc/meminfo or look in the process manager after booting wth this argument I still see all the RAM: ~2 GB. Am I using this boot argument incorrectly? The boot configuration (before I add anything) looks like this: insmod ext2 set root=(hd0,1) search --no-floppy --fs-uuid --set 10270f21-1c42-494b-bd3f-813c23f6d\ 518 linux /boot/vmlinuz-2.6.32-22-generic root=UUID=10270f21-1c42-494b-b\ d3f-813c23f6d518 ro quiet splash initrd /boot/initrd.img-2.6.32-22-generic The way I did this was that I added the mem=1024m after the last line and pressed Ctrl+x (Emacs save and boot the kernel) and the system booted. I tried adding mem=1024m to the end and the beginning of this list and it appeared to not change the RAM allocation.

• Problems with variadic function

  - by morpheous

  I have the following function from some legacy code that I am maintaining. long getMaxStart(long start, long count, const myStruct *s1, ...) { long i1, maxstart; myStruct *s2; va_list marker; maxstart = start; /*BUGFIX: 003 */ /*(va_start(marker, count);*/ va_start(marker, s1); for (i1 = 1; i1 <= count; i1++) { s2 = va_arg(marker, myStruct *); /* <- s2 is assigned null here */ maxstart = MAX(maxstart, s2->firstvalid); /* <- SEGV here */ } va_end(marker); return (maxstart); } When the function is called with only one myStruct argument, it causes a SEGV. The code compiled and run without crashing on Windows XP when I compiled it using VS2005. I have now moved the code to Ubuntu Karmic and I am having problems with the stricter compiler on Linux. Is anyone able to spot what is causing the parameter not to be read correctly in the var_arg() statement? I am compiling using gcc version 4.4.1 Edit The statement that causes the SEGV is this one: start = getMaxStart(start, 1, ms1); The variables 'start' and 'ms1' have valid values when the code execution first reaches this line.

• calling startActivity() inside of a instance method - causing a NullPointerException

  - by Cole

  Heya - I'm trying to call startActivity() from a class that extends AsyncTask in the onPostExecute(). Here's the flow: Class that extends AsyncTask: protected void onPostExecute() { Login login = new Login(); login.pushCreateNewOrChooseExistingFormActivity(); } Class that extends Activity: public void pushCreateNewOrChooseExistingFormActivity() { // start the CreateNewOrChooseExistingForm Activity Intent intent = new Intent(Intent.ACTION_VIEW); **ERROR_HERE*** intent.setClassName(this, CreateNewOrChooseExistingForm.class.getName()); startActivity(intent); } And I get this error… every time: 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): FATAL EXCEPTION: main 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): java.lang.NullPointerException 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at android.content.ContextWrapper.getPackageName(ContextWrapper.java:120) 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at android.content.ComponentName.(ComponentName.java:62) 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at android.content.Intent.setClassName(Intent.java:4850) 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at com.att.AppName.Login.pushCreateNewOrChooseExistingFormActivity(Login.java:47) For iOS developers - I'm just trying to push a new view controller on to a navigational controller's stack a la pushViewController:animated:. Which apparently - is hard to do on this platform. Any ideas? Thanks in advance! UPDATE - FIXED: per @Falmarri advice, i managed to resolve this issue. first of all, i'm no longer calling Login login = new Login(); to create a new login object. bad. bad. bad. no cookie. instead, when preparing to call .execute(), this tutorial suggests passing the applicationContext to the class the executes the AsyncTask, for my purposes, as shown below: CallWebServiceTask task = new CallWebServiceTask(); // pass the login object to the task task.applicationContext = login; // execute the task in the background, passing the required params task.execute(login); now, in onPostExecute(), i can get to my Login objects methods like so: ((Login) applicationContext).pushCreateNewOrChooseExistingFormActivity(); ((Login) applicationContext).showLoginFailedAlert(result.get("httpResponseCode").toString()); ... hope this helps someone else out there! especially iOS developers transistioning over to Android...
