Could somebody explain what this error means?

What is ip, sp and what does the numbers stand for?

If I grep -i "general protection ip" messages* I get below output. It is happening quite often and we need to restart php, db2 etc to make things work again. Not sure if below is related to it but we need to investiga it too.

I need to run tscon.exe 0 /dest:console remotely = not manually on Windows7 as an administrator. More info here How to use tscon on Windows7?

I did my research and

• OPTION 1 - runas

for user root (no password) on computer yogurt works

C:\>runas /user:yogurt\root cmd
Enter the password for yogurt\root:
Attempting to start cmd as user "yogurt\root" ...

for user administrator (I thought the the password is blank too) on computer yogurt doesn't work. I am asked for password, hit the enter and

C:\>runas /user:yogurt\administrator cmd
Enter the password for yogurt\administrator:
Attempting to start cmd as user "yogurt\administrator" ...
RUNAS ERROR: Unable to run - cmd
1327: Logon failure: user account restriction. Possible reasons are blank passwo
rds not allowed, logon hour restrictions, or a policy restriction has been enforced.

• OPTION 2 - setting properties of a batch file so it always runs as administrator. The 'privilege level' section is greyed out for me under Compatibility level. So I am not able to tick the check box Run this program as an administrator

I need to run overnight automation testing using RFT and IE on Windows7 virtual machine. I found that restarting the Windows box before the testing starts helps.

I am moving the production environment from Windows XP to Windows 7. RFT used to complain when running RFT scripts that CRFCN0557E: Activation failed when running under a Terminal Services environment. This may be caused by using a minimized terminal window - try playing back without minimizing the terminal window (it does not need to be full-screen).

Running tscon.exe 0 /dest:console prior starting any RFT script fix the error on Windows XP. But not on Windows7.

I did some research and was trying for hours to fix that but nothing helped. There is no screen saver turned on on Windows7.

I tried to run both but nothing helped.

tscon.exe 0 /dest:console
tscon.exe 1 /dest:console

On Windows7 tscon returns

{ErrorPrintf(): LoadString failed, Error 15105, (0x00003B01)}
Error [15105]:The resource loader cache doesn't have loaded MUI entry.
Error [0]:The operation completed successfully.

On Windows XP tscon returns

Could not connect sessionID 0 to sessionname console, Error code 7045
Error [7045]:The requested session access is denied.

I just double checked that running tscon.exe 0 /dest:console on Windows XP solves the issue. Cannot understand the output of the tscon command then.

Any idea how I can run RFT scripts after I restart the Windows box automatically? Preferably without involving any other computer. I was even thinking to use the old Windows XP to make remote desktop session to make RFT happy. I hope there is other better solution to that.

The openSUSE server name is 'darkhelmet'. I want to create an alias 'dh' for it. So I can also type 'ssh dh' and 'http://dh' would work too.

What file/files and where do I have to edit to make this happen?

Extract from /etc/hosts from darkhelmet

Our RAID5 (using Adaptec 3085) stopped working because one of the hdd is broken. How can I identify which one it is?

Is vSphere Web Client (Server) available on linux?

Based on vSphere 5 Documentation Center it seems to me that only Windows platform is supported.

It would be great not to run Windows in VirtualBox to manage our virtual machines.

this happens when I restart the lighttpd and it backups the old log and creates new one.

Is there any way so I don't have to changed permissions or ownership for that file every time the server is restarted and new log file created?

the file in question before doing chmod 777 * in the log directory was

-rw-r--r-- 1 root eduserver 1.9M Jun 16 13:41 access.log
-rwxrwxrwx 1 root eduserver  79K Apr 29 09:45 access.log-20110429.bz2*

db2 list database directory gives me

Database 1 entry:

 Database alias                       = M
 Database name                        = M
 Local database directory             = /var/lib/edumate/database

 Catalog database partition number    = 0
 Alternate server hostname            =
 Alternate server port number         =

buuuuut

db2 drop database M gives me

SQL1013N  The database alias name or database name "M       " could not be 
found.  SQLSTATE=42705

and /var/lib/edumate/database/db2inst1/NODE0000 doesn't have M directory

any suggestion on how I can remove the database m from the system?

db2 restore db databaseName from Directory doesn't work (hangs there and does nothing, no error, no time out) for me if the Directory is a nfs mounted directory. Any idea how to make it work?

• db2 v 9.7
• mounted from / to SuSe

Update I

db2 restore database RATIONAL from /var/lib/edumate/backup2/ TAKEN AT 20110523123431 into RATIO33 When I restore from NOT mounted it takes about 1-2 minutes to successfully restore the same database.

the restore command never finishes. I mean it won't give me command line prompt back. But the log file....

The above command does what I want but what about the ::1 part?

/opt/eduserver/eduserver gives me options:

Usage: /opt/eduserver/eduserver {start|stop|startphp|startwww|startooo|stopphp|stopwww|stopooo|restartphp|restartwww|restartooo|status|restart|reload|force-reload}

where memcache is php module there is memcache.ini in /opt/eduserver/etc/php/conf.d.

I want to clear the memcache from command line. Can I do it somehow without 'touching' any other part of the web server?

we have a server (ESXi virtual machine) at work that time to time gets frozen because of "kernel panic: Out of memory and no killable processes..."

Host's memory is 12GB.

Configuration of virtual machine

• VMware ESXi
  • VM version 7
  • 2 CPU
  • Memory 8192
  • memory reservation 0, memory limit setting = unlimited

• SuSe 11.3 (64 bit) + kernel 2.6.34-12

• firebird, postresql, db2

• php5.3, PHP-FPM, LIGHTTPD, MEMCACHED, OOo

the comp is NOT heavily used, it crashes once a day, once in two days. Sometimes it happends over weekned.

How can I find out what is causing the server to crash?

extract from vmware.log file

UPDATE I (bit of /var/log/messages)

extract from /var/log/messages where it all (probably) starts. I am going to remove /opt/eduserver/bin/php from cron and we will see if the crash is going to happen again.

I want to run

• a shell script restore
• as postgres user
• from php script (the user name is php)
• using sudo (so password is not required)

the script will have few lines of code, something like

dropdb <database name>
psql -c "create database <database name> with encoding 'unicode';" -U edutemplate1
psql -d <database name> -f edu.hourly.sql 

• what would be the sudo command syntax to run the script restore

• what would be the sudoers syntax to allow php user to run restore script as postgres user?

• Sudo version 1.7.2p7

• Linux testing 2.6.34-12-desktop #1 SMP PREEMPT 2010-06-29 02:39:08 +0200 x86_64 x86_64 x86_64 GNU/Linux

UPDATE

the first part of the question was already answered on SO sudoers-syntax-to-run-shell-script-as-php-user

UPDATE2

I added php ALL=(postgres) NOPASSWD: /usr/bin/id to /etc/sudoers and then did su php and then sudo -su postgres /usr/bin/id but I am asked for postgres' password. If I issue the same sudo command under the user root I will get correct output 'uid=26(postgres) gid=26(postgres) groups=26(postgres)'

UPDATE3

updating sudoers to php ALL=(postgres) NOPASSWD: ALL makes it work ...

I have working jail ssh to one directory.

I would love to give r/w access for the jail ssh user to few directories. For example

• /tmp/user
• /home/user
• /srv/www/user

is that possible?

let's say the current permissions are www-data:www-data and I do not want to touch that. I am not sure if the web server would like that.

On the other hand I do not want to add this new user to www-data group as I want him to have access to only some website data directories.

Is anything like that possible on linux?

can I set up

• a secure ftp for somebody (not a current user on the system)
• for 2 different directories on Ubuntu
• inside public_html?

I don't want to give the user pure ssh account right now.

Any other upload,download,delete file secure way is good too. nginx is available not apache2.

is there any web base management tool for nginx?

I basically need

1. add new domain to my solution
2. create new email addresses ( there will be more than 50 of them in the future per domain)
3. forward everything from the new email address somewhere else. I guess I can redirect the email to make the whole solution easier and not to have real account on my linode at all.
4. be able to send emails from my VPS box.
5. it would be nice to be able read the emails via web interface if I don't redirect them and keep a local copy.

VPS would probably run Debian

typing www.server.com.au in a web browser works fine I want to be able to access the web by entering server.com.au too

• A name record exists only for www.server.com.au
• CNAME for both and A name for server.com.au don't exist

my /etc/apache2/listen.conf contains lines

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName server.com.au
    ServerAlias server.com.au 
    DocumentRoot /srv/www/htdocs/www.server.com.au/www
</VirtualHost>

and list of virtual servers gives me

[root][saas1 /srv/www/htdocs/www.server.com.au/www] httpd2 -S
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:80                   is a NameVirtualHost
     default server server.com.au (/etc/apache2/listen.conf:47)
     port 80 namevhost server.com.au (/etc/apache2/listen.conf:47)

but http://server.com.au is not accessible

I restart the server by httpd2 -k restart

The screen shot below is made using firebug. The firefox <-> web server communication captured happened after clicking login button. But I cannot see any redirection in my firefox. Does that mean that firefox and web server communicated only on http headers level?

I have ready script in ruby/mechanize to scrape some details from a forum. I tested/coded it using vBulletin.org forum. Then I managed to log into my test forum and happily moved to finalize my script using the right forum. But I cannot log in. My script returns only the login page which I assume is 'not successful login attempt'.

• Is that possible that somebody would explain the screenshot below to me?

  • In particular why there is 11 lines? Why not just one?
  • If I can understand only kind of blindly/without thinking replies to the web server. Am I right?

• firefox sends in the post when I click login buttonauth_username=myusername&auth_password=mypassword&auth_login=Login but my script sendsauth_username=radek&auth_password=mypassword is that ok or the &auth_login=Login part must be presented?

• Is there any chance to simulate such communication let's say in ruby?

• or I was thinking if I can record the communication and then replay in my script (if possible)

html of the login page

<form class="login" method="post"> <fieldset>
<legend>Members Login</legend> 

<div>
<label for="auth_username">Username</label> <input id="auth_username" name="auth_username">
</div>

<div>
<label for="auth_password">Password</label> <input id="auth_password" name="auth_password" type="password">
</div>

</fieldset>
<div class="buttons">
<input name="auth_login" type="submit" value="Login"><p class="note"><a href="/forgotpassword">Forgot your password?</a></p>

</div>

</form>

my ruby script

require 'rubygems'
require 'mechanize'
#agent = WWW::Mechanize.new

agent = WWW::Mechanize.new 

page = agent.get("http://www.vbulletin.org/forum/index.php")

login_form = page.form_with(:action => 'login.php?do=login')


puts 
login_form.fields.each { |f| puts "#{f.name} : #{f.value}" }    
login_form['vb_login_username'] = 'user name'
login_form['vb_login_password'] = ''

page = agent.submit login_form

output = File.open("login.html", "w") {|f| f.write(page.parser.to_html) }

mechanize log from the try of login that doesn't work
