I do project and I use MySql. I like HeidiSql interface and generally this, so I would like to connect to my local database. But I really feel and maybe I am dumb because whatever host name I put I have errors. Anyway when I type ##hostname in cmd I see my windows authentication username, which also does not work for me.
Mysql Workbench work properly...
Default authentication plugin for MySQL has been changed in recent versions. Not all client programs out there have added support for it yet. You can check if HeidiSQL has released any latest version which adds this support. If it is not, then only solution is to change default authentication plugin on MySQL server and recreate the user. It is described in below links.

I have installed ejabberd on an AWS EC2 instance and am using the smack library to connect to it with my android app. At the moment the ejabberd server is using mnesia as the database, however I want to perform some complex queries on some of the data (mainly the MUC room names), as SQL will predominantly the best solution for this, I was wondering if it was possible to replicate the required data to an external MySQL database that I could then query.
Is this possible or am i better looking at a different approach to this problem?
There is no module built into ejabberd to replicate data in Mnesia to MySQL. However, the usual approach is to use the backend you need for each feature. If you want mod_muc to store data into MySQL instead of Mnesia, you can just change the backend to odbc (which means it will store data for that module in a relational database).
You can refer to ejabberd documentation for MUC module: http://docs.ejabberd.im/admin/guide/configuration/#modmuc
Once your MySQL is configured and schema is loaded, you can set db_type to odbc on a case by case basis to choose MySQL for that module.
Im learning how to build a simple web app using PHP and MySQL. Tools:
-XAMPP for database, web and php servers
-Sublime for writing the code itself
-Mac OSX Yosemite
- Workbench for database creation
I'm having trouble understanding (and finding a good tutorial) how Workbench actually works. If I got things correctly, I need to create a connection between the Workbench (tool) and the database which sits "inside" the database server? In my case, provided by XAMPP.
After I get these two talking, I then create, edit, etc. tables inside this database, right?
Currently I have two MySql connections on the homescreen, please see attached file.
Thanks!
It's basically just the connection/transfer method. You can connect to a MySQL server via a named pipe if such ability is provided by the operating system OR via TCP connection which is generally for network access but also works and is widely used for localhost connections.
It is transparent to the user and should not affect the communication between server and the client. Those two will connect to the same database using different types of communication channels.
Amazon officially states: "Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS."
I don't get this. Amazon RDS is accessible via web services and there a client libraries (like the one for .Net).
So if I have an existing .Net application that uses a DAL which in turn queries MySQL, how can I make the same DAL talk to the Amazon RDS (via the web services). Or am I missing something here?
Amazon RDS is pure MySQL, accessible by your app the same way as any other MySQL database; the web services interface to RDS is purely for creation, deletion, and modification of the DB instances, not the DB data. From their FAQ:
Q: How do I access my running DB
Instance?
Once your DB Instance is available,
you can retrieve its
endpoint via the DescribeDBInstance
API. Using this endpoint you can
construct the connection string
required to connect directly with your
DB Instance using your favorite
database tool or programming language.
In order to allow network requests to
your running DB Instance, you will
need to authorize access. For a
detailed explanation of how to
construct your connection string and
get started, please refer to our
Getting Started Guide.
This is the part of the Getting Started Guide you need -- it explains how to get the hostname of your new instance so you can connect to it, authorize the instance for access from the client, and then connect using the MySQL command-line client (as an example):
$ rds-describe-db-instances --headers
$ rds-authorize-db-security-group-ingress default --cidr-ip 192.0.2.0/30 --headers
$ mysql -h myinstance.crwjauxgijdf.us-east-1.rds.amazonaws.com -P 3306 -u mymasteruser -p
Amazon RDS is just a normal server with normal MySQL access. There's only the webservice that handles instance creation etc., but everything mysql related is still the same.
Tackling a strange scenario here.
We use a proprietary workstation management application which uses mySQL to store its data. Within the application they provide number of reports, such as which user logged into which machine at what time, all the software products installed on the monitored machines, so on and so forth. We are looking to do a different set of reports, however, they do not support custom reports.
Since their data is being stored in mySQL, I gather I can do the reporting manually. I don't have valid credentials to connect to the mySQL server though. Is there anyway for me to create a user account in the mySQL server? I do not want to reset the root password or anything account that might be in there, as it might break the application.
I have full access to the Windows 2003 server. I can stop and restart services, including the mySQL server. To the actual mySQL server, I only have basic access through the GUI provided by the software. I can't connect to it directly through CLI or through another tool (due to the lack of credentials).
I apologize if it came off as if I'm trying to get unauthorized access to the mySQL server. I have contacted the software company, and as of today it's been two weeks without a response from them. I need to get to the data. I have full access to the physical box, I have admin privileges on it.
You'll want to use the MySQL password recovery process. Follow these instructions, except replace the password reset query with a query to add a new user. The new user query would be something like:
GRANT ALL ON *.* TO 'myuser'#'localhost' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
That will create a new user "myuser" with the password "mypassword", who may log in to MySQL through the local system's CLI. You can then use the MySQL Administrator GUI (download here) and update user permissions so you can log in from other systems on the network. Or use the GRANT statement from the CLI, if that's more your style.
Do you have access to the MySQL server in question?
As in, what access do you have beyond what a regular user would? You should try to go through those routes before you "hack" your way in there, since that may or may not be feasible with that software.
odds are there are triggers on the database side keeping a log so when you hack yourself into the database they will know when and how you did it. Not a good idea.
I assume I really should not answer this one, but it's just too much fun.
Look at This page about SQL injections. That should cover your needs.
This page shows how to add user accounts to mySQL
I would try entering the following in random user input fields:
p'; INSERT INTO user VALUES
('localhost','myNewAdmin',PASSWORD('some_pass'),
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
and then
p'; FLUSH PRIVILEGES;
p'; is intended to close the regular question. e.g -
Normal question is:
"Select Adress from cusomers where custName = ' + $INPUT + ';
becomes
Select Adress from cusomers where custName = 'p'; INSERT INTO user
VALUES('localhost','myNewAdmin',PASSWORD('some_pass'),
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
One thing that comes in mind is sniffing the database communication and hope it's not encrypted. If it is encrypted try changing the configuration not to use SSL and restart mysql. A good sniffer that I use is Wireshark
From mysql 5.0 documentation:
MySQL supports secure (encrypted)
connections between MySQL clients and
the server using the Secure Sockets
Layer (SSL) protocol. This section
discusses how to use SSL connections.
It also describes a way to set up SSH
on Windows. For information on how to
require users to use SSL connections,
see the discussion of the REQUIRE
clause of the GRANT statement in
Section 12.5.1.3, “GRANT Syntax”.
The standard configuration of MySQL is
intended to be as fast as possible, so
encrypted connections are not used by
default. Doing so would make the
client/server protocol much slower.
Encrypting data is a CPU-intensive
operation that requires the computer
to do additional work and can delay
other MySQL tasks. For applications
that require the security provided by
encrypted connections, the extra
computation is warranted.
MySQL allows encryption to be enabled
on a per-connection basis. You can
choose a normal unencrypted connection
or a secure encrypted SSL connection
according the requirements of
individual applications.
Secure connections are based on the
OpenSSL API and are available through
the MySQL C API. Replication uses the
C API, so secure connections can be
used between master and slave servers.
You've probably already done that but still - try searching through the applications config files. If there's nothing - try searching through the executables/source code - maybe it's in plaintext if you're lucky.
