• Problem installing the latest eclipse IDE

  - by James

  I'm running ubuntu 11.04. I'm trying to install the latest "eclipse for java developers" IDE (version Indigo 3.7.1). I have downloaded and extracted it. I attempt to run it by changing to the extracted folder and executing ./eclipse This produces the following errors in the terminal: /usr/lib/gio/modules/libgiobamf.so: wrong ELF class: ELFCLASS64 Failed to load module: /usr/lib/gio/modules/libgiobamf.so /usr/lib/gio/modules/libgvfsdbus.so: wrong ELF class: ELFCLASS64 Failed to load module: /usr/lib/gio/modules/libgvfsdbus.so And then a dialog opens with this error message: JVM terminated.

• Trying to install apache 2.4.10 with openssl 1.0.1i

  - by AlexMA

  I need to install apache 2.4.10 using openssl 1.0.1i. I compiled openssl from source with: $ ./config \ --prefix=/opt/openssl-1.0.1e \ --openssldir=/opt/openssl-1.0.1e $ make $ sudo make install and apache with: ./configure --prefix=/etc/apache2 \ --enable-access_compat=shared \ --enable-actions=shared \ --enable-alias=shared \ --enable-allowmethods=shared \ --enable-auth_basic=shared \ --enable-authn_core=shared \ --enable-authn_file=shared \ --enable-authz_core=shared \ --enable-authz_groupfile=shared \ --enable-authz_host=shared \ --enable-authz_user=shared \ --enable-autoindex=shared \ --enable-dir=shared \ --enable-env=shared \ --enable-headers=shared \ --enable-include=shared \ --enable-log_config=shared \ --enable-mime=shared \ --enable-negotiation=shared \ --enable-proxy=shared \ --enable-proxy_http=shared \ --enable-rewrite=shared \ --enable-setenvif=shared \ --enable-ssl=shared \ --enable-unixd=shared \ --enable-ssl \ --with-ssl=/opt/openssl-1.0.1i \ --enable-ssl-staticlib-deps \ --enable-mods-static=ssl make (would run sudo make install next but I get an error) I'm essentially following the guide here except with newer slightly newer versions.

I would prefer to just use aptitude, but unfortunately the versions I need aren't available yet. If anyone knows how to fix the linker problem (or what I think is a linker problem), or knows of a better way to tell apache to use a newer openssl, it would be greatly appreciated; I've got apache 1.0.1i working otherwise.

• Problems starting MySQL on Mac OS X

  - by Jon

  I am not able to start MySQL server on Mac OS X 10.4.11. MySQL was installed using Macports. MySQL was running fine until it suddenly died without any obvious reason. When running "mysql", I get the error message: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2) If I try to start MySQL manually, I get the following error message: sudo /opt/local/share/mysql5/mysql/mysql.server start Starting MySQL/opt/local/share/mysql5/mysql/mysql.server: line 159: kill: (636) - No such process ERROR! In /etc/mysql/my.cnf I have: socket = __PREFIX/var/run/mysqld/mysqld.sock But the path "opt/local/var/run/mysqld/" does not exist on my system. I tried to change the socket path to "__PREFIX/var/run/mysql5/ mysqld.sock" (which is where the socket is located). Unfortunately, this did not help either. Owner and Permissions for /opt/local/var/run/mysql5/ are correctly set. Any suggestions on how to start MySQL again? Thanks for your advice.

• How to create a PPA for C++ program?

  - by piotr

  My questions are: c++/gtkmm project created with NetBeans. How to make package to PPA from this? I have created target files structure (*.desktop, iconfile, ui glade files). Binary goes to /opt/extras.ubuntu.com/myagenda/bin/myagenda. There is also a folder of glade files, that must go to /opt/extras.ubuntu.com/myagenda/bin/myagenda/ui. Desktop file goes to /usr/share/applications/myagenda.desktop. Icon goes to /usr/share/icons/hicolor/scalable/apps/myagenda.svg As you see, there is really small amount of files. Now, how to manage all this stuff, to create package on PPA, which knows where and how put this files to their targets? +-- opt ¦   +-- extras.ubuntu.com ¦   +-- myagenda ¦   +-- bin ¦   ¦   +-- myagenda ¦   +-- ui ¦   +-- item_btn_delete.png ¦   +-- item_btn_edit.png ¦   +-- myagenda.png ¦   +-- myagenda.svg ¦   +-- reminder.png ¦   +-- ui.glade +-- usr +-- share +-- applications ¦   +-- myagenda.desktop +-- icons +-- hicolor +-- scalable +-- apps +-- myagenda.svg Update: Created install file in debian directory with targets: data/myagenda /opt/extras.ubuntu/com/myagenda/bin data/ui/* /opt/extras.ubuntu/com/myagenda/ui data/myagenda.desktop /usr/share/applications data/myagenda.svg /usr/share/icons/hicolor/scalable/apps After dpkg-buildpackage it builds, but for amd64 architecture.

• phpize: m4 error just in one extension

  - by Francois

  On Linux, I installed php 5.3.8 from source. Using phpize for installing an extension works fine but not on one specific extension (mysqlnd). # cd /opt/php/5.3.8/ext/pdo && /opt/php/5.3.8/bin/phpize ... this runs ok # cd /opt/php/5.3.8/ext/mysqlnd && /opt/php/5.3.8/bin/phpize Cannot find config.m4. Make sure that you run '/opt/php/5.3.8/bin/phpize' in the top level source directory of the module` As you can see error can not be that I am not on top level source directory since I am. I tried to call phpize from ext folder - did not work either! For info I have m4 installed Any idea? Thanks :)

• Access forbidden 403 error in xampp

  - by Ramvignesh

  I am very new to xampp. I have made a fresh xampp install with the following commands. sudo su cd /tmp wget bit.ly/1cmyrUo -O xampp-32bit.run chmod 777 ./xampp-32bit.run sudo ./xampp-32bit.run Then I made a perl file to check whether my xampp works. The following is my sample.pl file content. #!usr/bin/perl print "content-type:text/html\n"; print(header()); use CGI qw(:standard); print(start_html()); print "Hello. I am ram"; print(end_html()); After copying my perl file from /home/vicky/desktop to /opt/lampp/cgi-bin. I started my xampp with the following command. /opt/lampp/lampp start Then I ran my sample.pl in the localhost with the help of the http://localhost/cgi-bin/sample.pl in my mozilla browser. I just got the following window. I found only answers relating to the 'new security concept error' and 'accessing virtual host issue'. I did came across an askubuntu query, a bid similar to that of mine. It had no answers but some comments. One comment suggested to change the file permissions. It directed to get help from here. It said to change the directory permission as 755 and file permission as 644 to resolve this kind of issue. When I tried to do that, I came to know that my cgi-bin directory already had 755 permission and my sample.pl had 644 permission. I have no solutions now. PostScript: I have attached the content of my /opt/lampp/apache2/conf/httpd.conf file. Hope this will help the answer-providers to understand my problem completely.

• How to force a new Notification in notify-osd to show up without waiting for the earlier one to exit?

  - by Nirmik

  I have made a script(and a .desktop shortcut leading to this script) for starting and stoping xampp... It checks the status of xampp and accordingly either starts or stops xampp. Now i have assigned a notification as soon as the script is started to display "Starting xampp..." or "Stopping xampp..." and then when xampp is started or stopped,it displays "Xampp started..." or "Xampp stopped..." I've used notify-send to show notification as seen in the script below Now the thing is that here,the second notification waits for the 1st one to disappear and then pops up even if xampp has started/stopped. I want the new notification to appear immediately by forcing the earlier one to exit before the completion of its life-cycle. This can be seen to take plce when you activate/deactivate wireless/networking immediately... For example the "Wireless enabled" comes up on selecting enable wireless and if you immediately select disable wireless,the "Wireless disabled" notification comes up without waiting for "Wireless enabled" notification to complete its life-cycle. So how do i achieve this? #!/bin/sh SERVICE='proftpd' if ps ax | grep -v grep | grep $SERVICE /dev/null then notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "Stopping XAMPP..." && gksudo /opt/lampp/lampp stop && notify-send -i /opt/lampp/htdocs/xampp/img/logo- small.gif "XAMPP Stoped." else notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "Starting XAMPP..." && gksudo /opt/lampp/lampp start && notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "XAMPP Started." fi On the man page for notify-send I found --urgency=LEVEL or -u where levels are low, normal, critical. Is this of any use? making it critical? Also I tried it with the command- notify-send -u=critical"Testing" but that dint work...it gives the error- Unknown urgency criticalTesting specified. Known urgency levels: low, normal, critical. or if I give the command notify-send -u=LOW"Testing" it gives me error missing argument to -u Any relation??

• why can't macports find make

  - by GeoffreyF67

  I am trying to run macports like thus: port install php5 When I do so, however, I get this error: Error: Unable to open port: can't read "build.cmd": Failed to locate 'make' in path: '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its MacPorts configuration time location, did you move it? So I looked at my path: declare -x PATH="/Developer/usr/bin:/opt/subversion/bin:/opt/local/bin:/opt/local/sbin:/usr/local/php5/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin" and then looked to make sure make was in one of those dirs: ls -l /Developer/usr/bin/make $ lrwxr-xr-x 1 root admin 7 Aug 7 16:47 /Developer/usr/bin/make -> gnumake And typing: make produces: make: *** No targets specified and no makefile found. Stop. So I know that it's there. But macports can't find it. Any ideas? G-Man

• dot42 vs Xamarin to develop in C# for Android phones [on hold]

  - by opt

  does anyone have experience with both dot42 and Xamarin to develop C# apps for Android? Could you please say why one should prefer one over the other? I like the free Visual Studio integration that is offered by dot42 (while Xamarin requires a subscription for this, and the business one which is quite expensive). I would also like to know if Visual Studio integration actually means that one could use all libraries available for desktop apps. Thank you.

• Apache virtual hosts - Resources on website not loaded when accessed from other hostname than localhost

  - by Christian Stadegaart

  Running virtual hosts on Mac OS X 10.6.8 running Apache 2.2.22. /etc/hosts is as follows: 127.0.0.1 localhost 3dweergave studio-12.fritz.box 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost Virtual hosts configuration: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot "/opt/local/www/3dweergave" ServerName 3dweergave ErrorLog "logs/3dweergave-error_log" CustomLog "logs/3dweergave-access_log" common <Directory "/opt/local/www/3dweergave"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> <VirtualHost *:80> ServerName main </VirtualHost> This will output the following settings: *:80 is a NameVirtualHost default server 3dweergave (/opt/local/apache2/conf/extra/httpd-vhosts.conf:21) port 80 namevhost 3dweergave (/opt/local/apache2/conf/extra/httpd-vhosts.conf:21) port 80 namevhost main (/opt/local/apache2/conf/extra/httpd-vhosts.conf:34) I made 3dweergave the default server by putting it first in the list. This will cause all undefined virtual hosts' names to load 3dweergave, and thus http://localhost will point to 3dweergave. Of course, normally, the first in the list is the virtual host main and localhost will point to main, but for testing purposes I switched them. When I navigate to http://localhost, my CakePHP default homepage shows as expected: Screenshot 1 But when I navigate to http://3dweergave, my CakePHP default homepage doesn't show as expected. It looks like every relative link to resources are not accepted by the server: Screenshot 2 For example, the CSS isn't loaded. When I open the source and click on the link, it opens the CSS file in the browser without errors. But when I run FireBug while loading the webpage, it seems that the CSS file isn't retrieved. (<link rel="stylesheet" type="text/css" href="/css/cake.generic.css" />) How can I fix this unwanted behaviour?

• Redirect packages directed to port 5000 to another port

  - by tdc

  I'm trying to use eboard to connect to the FICS servers (http://www.freechess.org), but it fails because port 5000 is blocked (company firewall). However, I can connect to the server through the telnet port (23): telnet freechess.org 23 (succeeds) telnet freechess.org 5000 (fails) Unfortunately the port number is hardcoded (see here: http://ubuntuforums.org/archive/index.php/t-1613075.html). I'd rather not have to hack the source code as the author of that thread ended up doing. Can I just forward the port on my local machine using iptables? I tried: sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 5000 -j REDIRECT --to-port 23 and sudo iptables -t nat -I OUTPUT --src 0/0 -p tcp --dport 5000 -j REDIRECT --to-ports 23 but these didn't work... Note that: $ sudo iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain POSTROUTING (policy ACCEPT) target prot opt source destination

• Change XAMPP's htdocs web root folder to another one

  - by vitto

  I'm trying to change the XAMPP's web root default directory /opt/lampp/htocs to another one like /home/me/Dropbox/public_html without success. I've edited the file /opt/lampp/etc/httpd.conf # old line: DocumentRoot "/opt/lampp/htdocs" DocumentRoot "/home/me/Dropbox/public_html" #...etc... # old line: <Directory "/opt/lampp/htdocs"> <Directory "/home/me/Dropbox/Work/public_html"> # # Possible values for the Options directive are "None", "All", # or any combination of: # Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews # etc... I've did this as said in this article: Using Ubuntu One to synchronise htdocs? Then I've restarted Apache and I've got a permission error 403 on every page I've called with the web browser. So I've changed folder and files permission to 755. I've did this as said in this article: What file permissions should I set on web root? The problem still remains the same, I have the 403 error on every page I try to reach with the web browser. I have the same problem on a Mac using XAMPP. So everythig works fine if the folder remains the original /opt/lampp/htocs. How can I change it correctly?

• C# to develop Android app

  - by opt

  I am learning C# and I'm wondering if there is the potential to develop an Android app that satisfy the need that I'm going to explain. I would basically need an app that, when launched retrieves some data from a webpage (i.e. realtime stock prices), trim the xml to find the data i need and store this value into a variable. Then some calculation is performed on this data and the result is sent via email. It is already possible to launch an app automatically based on some conditions (e.g. every 5 minutes) by using the software Tasker. It is actually also possible to retrieve the data from a webpage and save to a Tasker variable or to a txt file somewhere in the phone (or Dropbox/Box...). But I would like to do that directly via an app so that everything is done "internally" once the app is launched. If that's possible, how should I proceed? Is there any good reference I can use to address my need?

• Maven - 'all' or 'parent' project for aggregation?

  - by disown

  For educational purposes I have set up a project layout like so (flat in order to suite eclipse better): -product | |-parent |-core |-opt |-all Parent contains an aggregate project with core, opt and all. Core implements the mandatory part of the application. Opt is an optional part. All is supposed to combine core with opt, and has these two modules listed as dependencies. I am now trying to make the following artifacts: product-core.jar product-core-src.jar product-core-with-dependencies.jar product-opt.jar product-opt-src.jar product-opt-with-dependencies.jar product-all.jar product-all-src.jar product-all-with-dependencies.jar Most of them are fairly straightforward to produce. I do have some problem with the aggregating artifacts though. I have managed to make the product-all-src.jar with a custom assembly descriptor in the 'all' module which downloads the sources for all non-transitive deps, and this works fine. This technique also allows me to make the product-all-with-dependencies.jar. I however recently found out that you can use the source:aggregate goal in the source plugin to aggregate sources of the entire aggregate project. This is also true for the javadoc plugin, which also aggregates through the usage of the parent project. So I am torn between my 'all' module approach and ditching the 'all' module and just use the 'parent' module for all aggregation. It feels unclean to have some aggregate artifacts produced in 'parent', and others produced in 'all'. Is there a way of making an 'product-all' jar in the parent project, or to aggregate javadoc in the 'all' project? Or should I just keep both? Thanks

• iptables issue on plesk

  - by Fred Rufin

  i don't know how to open a specific port (rtmp=1935) on my CentOS server using Plesk or itables. I created new rules for port 1935 i/o using Plesk/Modules/Firewall but this doesn't work. Nmap scanning tells me this : 1935/tcp filtered rtmp . So i decided to have look at my iptable using SSH (iptables -L), and iptables seems to contain my rules (tcp spt:macromedia-fcs): Chain INPUT (policy DROP) target prot opt source destination VZ_INPUT all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED REJECT tcp -- anywhere anywhere tcp flags:!FIN,SYN,RST,ACK/SYN reject-with tcp-reset DROP all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere Chain FORWARD (policy DROP) target prot opt source destination VZ_FORWARD all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED REJECT tcp -- anywhere anywhere tcp flags:!FIN,SYN,RST,ACK/SYN reject-with tcp-reset DROP all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere Chain OUTPUT (policy DROP) target prot opt source destination VZ_OUTPUT all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED REJECT tcp -- anywhere anywhere tcp flags:!FIN,SYN,RST,ACK/SYN reject-with tcp-reset DROP all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere Chain VZ_FORWARD (1 references) target prot opt source destination Chain VZ_INPUT (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT tcp -- anywhere anywhere tcp dpt:pop3 ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpts:filenet-tms:65535 ACCEPT udp -- anywhere anywhere udp dpts:filenet-tms:65535 ACCEPT tcp -- anywhere anywhere tcp dpt:cddbp-alt ACCEPT tcp -- anywhere anywhere tcp dpt:pcsync-https ACCEPT tcp -- localhost.localdomain localhost.localdomain ACCEPT tcp -- anywhere anywhere tcp dpt:macromedia-fcs ACCEPT udp -- localhost.localdomain localhost.localdomain Chain VZ_OUTPUT (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp spt:http ACCEPT tcp -- anywhere anywhere tcp spt:ssh ACCEPT tcp -- anywhere anywhere tcp spt:smtp ACCEPT tcp -- anywhere anywhere tcp spt:pop3 ACCEPT tcp -- anywhere anywhere tcp spt:domain ACCEPT udp -- anywhere anywhere udp spt:domain ACCEPT tcp -- anywhere anywhere ACCEPT udp -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp spt:cddbp-alt ACCEPT tcp -- anywhere anywhere tcp spt:pcsync-https ACCEPT tcp -- localhost.localdomain localhost.localdomain ACCEPT tcp -- anywhere anywhere tcp spt:macromedia-fcs ACCEPT udp -- localhost.localdomain localhost.localdomain My rules seems to be OK but there is no connection to 1935 port using a browser. I can connect to this port with SSH (typing "wget myServerIP:1935") but maybe this is because it is an SSH tunelling ? I don't know how to do.

  A similar problem has been reported here with no solution:https://www.centos.org/modules/newbb/print.php?form=1&topic_id=42696&forum=56&order=ASC&start=0 I've added and upgraded gcc to centos cd /etc/yum.repos.d wget http://people.centos.org/tru/devtools-1.1/devtools-1.1.repo yum --enablerepo=testing-1.1-devtools-6 install devtoolset-1.1-gcc devtoolset-1.1-gcc-c++ scl enable devtoolset-1.1 bash The result is this for my gcc [root@hhvm-build-centos cmake-2.8.11.1]# gcc -v Using built-in specs.

Is there a solution to this problem?

• Using mod_rewrite to mask /cgi-bin/abc as /def

  - by Alois Mahdal

  I have a seemingly easy task, but somehow I just can't get it to work: Some interesting lines from my httpd.conf: ... DocumentRoot "D:/opt/apache/htdocs" ... ScriptAlias /cgi-bin/ "D:/opt/apache/cgi-bin/" ... <Directory "D:/opt/apache/htdocs"> Options Indexes FollowSymLinks ExecCGI AllowOverride None Order allow,deny Allow from all </Directory> <Directory "D:/opt/apache/cgi-bin/"> AllowOverride None Options ExecCGI Order allow,deny Allow from all </Directory> (I know it's dumb but it's only a testing machine :D.) Now, I have d:\opt\apache\cgi-bin\expired.pl and I expect GET /licensecheck.php?code=123456. And I wish to fake client into thinking it speaks with /licensecheck.php, but actually return data by \expired.pl. What I tried was setting following at the end of http.conf: RewriteEngine on RewriteRule ^/licensecheck.php$ /cgi-bin/expired.pl [T=application/x-httpd-cgi,L] ...but it keeps 404-ing me, looking for cgi-bin directory (not cgi-bin\expired.pl) in my DocumentRoot! [error] [client 127.0.0.1] script not found or unable to stat: D:/opt/apache/htdocs/cgi-bin /cgi-bin/expired.pl and all other scripts in /cgi-bin/ work as expected, Only way I could make it work was actually putting the \expired.pl to DocumentRoot, but I don't want this, I want my cgi-bin neatly separated :)

  - by Iscariot

  Environment: Solaris 10 This mysql server has been up and running for 6 months now. Today all of a sudden it crashed.

The server try to open mysql, it stays open for 9-10 seconds and restarts the process. Below are the application logs.

• Apache can't get viewed from outside of my LAN

  - by Javier Martinez

  I fixed it in PORTS TRIGGER menu of my router. Thanks you anyway I have a weird problem related with (i think) my cable-router and my configured vhosts in Apache2. The point is I can't access from outside of my LAN to any of my configured vhosts if I set the http port of Apache to 80 and i add a NAT rule for it. Otherwise, if I set my Apache port to 81 (or any else) with its respective NAT rule on my router it works. My router is an ARRIS TG952S and I am using Apache/2.2.22 (Debian) ports.conf NameVirtualHost *:80 Listen 80 vhost1.mydomain.net.conf <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost1.mydomain.net ServerAlias vhost1.mydomain.net www.vhost1.mydomain.net vhost2.mydomain.net.conf <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost2.mydomain.net ServerAlias vhost2.mydomain.net www.vhost2.mydomain.net DNS records (using FreeDNS) are: mydomain.net --> pointing to another server vhost1.mydomain.net --> pointing to my server vhost2.mydomain.net --> pointing to my server iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination fail2ban-apache-noscript tcp -- 0.0.0.0/0 0.0.0.0/0 multiport dports 80,443 fail2ban-apache tcp -- 0.0.0.0/0 0.0.0.0/0 multiport dports 80,443 fail2ban-ssh tcp -- 0.0.0.0/0 0.0.0.0/0 multiport dports 22 Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain fail2ban-apache (1 references) target prot opt source destination RETURN all -- 0.0.0.0/0 0.0.0.0/0 Chain fail2ban-apache-noscript (1 references) target prot opt source destination RETURN all -- 0.0.0.0/0 0.0.0.0/0 Chain fail2ban-ssh (1 references) target prot opt source destination RETURN all -- 0.0.0.0/0 0.0.0.0/0 Thanks you
