Opening Multiple DB Connections to MySQL via SSH Tunneling

I'm connecting to a MySQL database through SSH. Specifically I'm using PuTTY to establish a connection, and then tunnel the port through 3306. Then I'm creating an ODBC Data source to my local 3306 port and using that datasource to open the connection in LabVIEW.
I'm looking to run queries in parallel, and to do that, I believe I need to open up multiple connections. Has anyone tried this before? Is there anyother way to do this?

Hi Jonathan,
I wasn't able to find too many resources on using multiple connections to a MySQL through SSH.
I was able to find this:
http://digital.ni.com/public.nsf/allkb/C49602A79827DDBE86256CE9005757D5
that might give you some more information.
I would try to open up multiple connections if the database supports it and try it that way.
If you have any troulbe with that route, feel free to let us know.
Sincerely,

ORA Connect via SSH Tunnel on Windows failed! LINUX works ...

Hello again,
i tried to establish a Oracle Client Connection via SSH Tunnel on WinXP Pro.
1. Opened SSH-Tunnel Connection with plink (putty)
TUNNEL: 10.5.1.111:1521 => localhost:1521
(plink works fine with telnet, MySQL Client and other stuff)
2. Connected with Oracle Client on Tunnel END => Localhost, Port 1521
3. WIth ORA8i i got: Paket Error, With ORA10g i get: TNS: no listener
plink works fine, so i dont think the problem is located there.
i tried, tnsnames.ora, easyconnect and TNS-Less. So i guess, its not related to the connection method.
i tried the same on LINUX ... ssh tunnel and sqlplus connect ... IT WORKS !
Does Oracle need an aditional Port?
Does it have Problems with WIN2UNIX Connections? (ORA DB is on UNIX)
tnx

Hi,
Hum..., I guess this not work!
Looking for this schema below, you need put the 1521 port
If you desire, access the www.ssh.com site and download other ssh program

Disable Non-Root Connections to WindowServer via SSH

I recall that in previous versions of Mac OS, one could not start an application in another user's workspace via SSH unless they were root, e.g. by running /Applications/Safari.app/Contents/MacOS/Safari at the prompt. The error given was something about being unable to make a connection to the windowserver. Root privileges were required to do so.
However, I note that now in Mountain Lion I can run, for example, the previous command and my Safari will pop up in the session of the currently logged in user, neither of us being root or even administators.
Is there a way to revert to the old behaviour (without disabling Remote Login, obviously)? I note some potential for evil, e.g. "/Applications/Utilities/Vine\ Server.app/Contents/MacOS/Vine\ Server &" to start a VNC server and, violá! surreptitious monitoring/control of active session...

This was previously not possible.
It has always been possible via the open(1) command. In any case, that doesn't matter. SSH access is unlimited access, unless you allow only public-key logins and specify a command to be executed in the authorized_hosts file. There is no security issue here.

Connection to MySQL via ODBC not working

Hello all together,
I've got a problem with the ODBC connection to MySQL. The connection via ODBC is established and things like tnsping are working.
When I select some data within the SQL*Plus environment, I get no real result. For example "select table_name from all_tables@mysql;" returns nothing.
My entry in listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME=odbc_mysql)
(ORACLE_HOME=D:\oracle\product\11.0.1\db_1)
(PROGRAM=dg4odbc)
My entry in tnsnames.ora:
MYSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA = (SID=odbc_mysql))
(HS=OK)
The initodbc_mysql.ora in ORACLE_HOME/hs/admin/:
HS_FDS_CONNECT_INFO = odbc_mysql
HS_AUTOREGISTER = TRUE
HS_DB_NAME = hsodbc
I tried some modifications but I still get no data from mysql database. When I try "select * from customer@mysql;" I get the correct number of records, the correct column names, but the content is always "¬¬¬¬". The odbc driver works, because with MS Access I can fetch the data. I'm using Oracle 11g Release 1 EE and MySQL ODBC 5.1.5.
What could be the reason for this?
Greetings,
Joerg

created in my UTF-8 Mysql DB your table and inserted a record; the select shows:
SQL> select * from "movieclass"@mysql;
idClass
ClassName
123
H e l l o
As you can see the content is there, the "space" between the letters is related to unicode. Each character is interpreted by 2 bytes and SQL*Plus wrongly displays both. Using iSQLPLus or SQLDeveloper does not show the "space" between the letters.
Here the data type mapping:
SQL> desc "movieclass"@mysql;
Name Null? Type
idClass NUMBER(3)
ClassName NOT NULL NVARCHAR2(50)
What's the exact version of DG4ODBC you're using? 11.1.0.7?
According to the listener file you're using DG4ODBC on Windows. There was a high/low byte issue in DG4ODBC for Windows. This issue is fixed in 11.1.0.7 and a certain patch. So I recommend you to get first the 11.1.0.7 patchset (if you don't already have it installed):
6890831 Oracle Database Family: Patchset
11.1.0.7.0 PATCH SET FOR ORACLE DATABASE SERVER 11.1.0.7.0
and then please apply also the latest patch:
8689191 Oracle Database Family: Patch
ORACLE 11G 11.1.0.7 PATCH 16 BUG FOR WINDOWS 32 BIT 11.1.0.7.0
There was a high/low byte issue

Remotley connect to mySql via mm.mysql

Hello,
I'm running WIN2k, JDK 1.2.1_004 and I'm trying to make a local java application to connect to mysql on my web server via mm.mysql. But it doesn't work
I get the following error:
SQLState: 08001
Message: No suitable driver
Vendor: 0
I've tried to connect via the ip:
Connection con = DriverManager.getConnection ("jdbc:mysql://64.176.118.240:3306/grattiskort_com?user=grattis&password=");
And domain name
Connection con = DriverManager.getConnection ("jdbc:mysql://grattiskort.com:3306/grattiskort_com?user=grattis&password=");
I have enabled remote connection in mysql config.
Do I need to install the driver on my web server too, and if so, how do I do that?
Does anyone have a clue what's wrong?
Regards,
Chrille

Connecting to MySQL via DW after Leopard install

I cannot connect to MySQL 5.041 through DW CS3 after
upgrading to Leopard. MySQL Admin and MySQL Query Browser both can
connect and make queries to the database. I just can't connect
through Dreamweaver. I get the "MySQL Error#: 2002" error which
states "Can't connect to local MySQL server through socket
'/var/mysql/mysql.sock' (2). Problem is there is no such
path.

There may be an updated needed for dreamweaver, however, I
did find some info about MySQL running on Leopard:
http://bugs.mysql.com/bug.php?id=32019
and some workarounds that I have not tested as being valid:

Using Workgroup Manager via SSH tunnel

Hi all,
I'm attempting to use the Workgroup Manager app to remotely administer a OS X Tiger Server box. The server sits inside my company's LAN behind a firewall, which only allows traffic to the server on ports 21 (ftp), 22 (ssh), 80 (http) and 311 (server admin with SSL, I believe). All services on those ports work fine.
My research on the net indicates that the Workgroup Manager app uses port 625, but since the hardware firewall is blocking traffic on that port to the server, I'd like to create an SSH tunnel to access it. I've tried the following command on my local machine (i.e., not the server):
$ sudo ssh -L 625:localhost:625 [email protected]
and am able to set up the tunnel with no problem. However when I try to connect Workgroup Manager (on the local machine) to localhost, it won't let me connect. So I tried telnetting to localhost port 625 (on the local machine) to see what's up, and received the following error:
$ telnet localhost 625
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
Am I missing something? I was under the impression that the SSH tunnel would allow me to access port 625 on the server via port 22. The software firewall is disabled on both machines, so it's not that. I'm not experienced with SSH tunnelling, so I could be totally wrong about the way this is supposed to work.
Thanks in advance!

A quick tcpdump here indicates that Workgroup Manager uses both 311 and 625 when establishing a connection to the server. It may be the lack of port 311 tunneling that's causing your problem.
$ sudo ssh -L 625:localhost:625 -L 311:localhost:311 [email protected]

Can Dreamweaver CS5 connect to MySQL via ODBC?

I am unable to make a direct connection to an external MySQL database because most hosting provider does not allow this type of connection due to security reasons. I am however able to make an ODBC connection to the database (which I am currently using to connect filemaker to our MySQL database).
How can I tell Dreamweaver CS5 to connect via the ODBC driver so I can see the MySQL content in my Dreamweaver project?
I am on a Mac running OS X 10.6.4.

You can't - at least not if you want to use Dreamweaver's server behaviors. Dreamweaver uses the original PHP MySQL extension. If you want to connect in any other way, you need to hand code everything yourself.
On the other hand, if you want to see the contents of your remote database in Dreamweaver, define your remote server as the testing server. Dreamweaver uploads a hidden folder to the remote server to connect to the database. Because the script is on your remote server, it's local to the MySQL database, so gets round the security issue. It then sends the details to your local computer.
A better solution, though, is to establish a local testing environment. It's more responsive and much more secure. http://www.adobe.com/devnet/dreamweaver/articles/setup_php.html.
By the way, the failure to get a reply is due, in part, to posting your question in the wrong forum. The forum for issues related to PHP/MySQL and other server-side technologies is http://forums.adobe.com/community/dreamweaver/dreamweaver_development.

Connection to mySQL via jdbc

I'm currently programming a GUI to access a database. Therefore I executed a query, which worked fine. But when I tried to exit my program with
System.exit(0)my DOS-Prompt crashes without exiting.
Now I tried it with a kind of minimalistic Connection like that:
Class.forName("org.gjt.mm.mysql.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/stock");
conn.close();Here the same problem occurs, so it must be the Connection that causes the error.
If I would exit the program right away after the Connection, that is
Class.forName("org.gjt.mm.mysql.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/stock");
conn.close();
System.exit(0);then the program exits properly. Unfortunately it doesn't make any sense to quit the program right after reading the data.
So, as you can guess, I'm quite confused. I used the same driver and the same database in another program on the same computer, and it works fine. So I'm left totally clueless.
I'm not using a special programming environment, I just write my code using UltraEdit. I've got installed Java 1.4.0 on my machine.
Any help is very appreciated

I don't get any.
It just crashes. There's neither an exception thrown nor any other error msg.

Can connect to MySQL via localhost, but not remotely!

Hi all!
I got a problem that I think you guys could help me with :)..
I have installed JDBC to make it possible to link my Java programs with MySQL databases. The installation worked just fine.
When I'm running my program with line:
Connection connection = null;
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/chat", "*****", "*****");...it works without any problems. I can handle information from the tables, add posts, delete posts and so on.
But when I'm trying to connect from an another computer, from school for an example, it doesn't connect. JBDC says it can't fint the mysql jbdc driver.
When I'm using this way I uses the line:
Connection connection = null;
connection = DriverManager.getConnection("jdbc:mysql://85.235.154.98:3306/chat", "*****", "*****");Like I said, this doesn't work at all.
How do I fix this problem?
Worth to mention maybe, is that I'm using Windows XP Home, and I have placed the mysql-connector-java-5.0.5-bin.jar in "C:\Program\Java\jre1.6.0_01\lib\ext"
I'm using Java version 1.6.0!
Please Help :)

But when I'm trying to connect from an another
computer, from school for an example, it doesn't
connect. So the database is on your home computer? And you are attempting to connect from the school?
JBDC says it can't fint the mysql jbdc
driver.Then it has nothing to do with connecting. That means your class path is wrong.
If it actually is a connection problem then you can do the following in a console window....
telnet 85.235.154.98 3306
There will be one of two results from the above after several minutes.
1. It will just sit there.
2. It will tell you it can't connect.
For 2 you have a problem that has nothing to do with java. Looking at your code will not fix it.
If it is 1 then something is wrong with your code and you should provide the exact exception.

Unable to direct connect to 6509 via SSH

I have a 6509 with s72033_rp-ADVIPSERVICESK9_WAN-M 12.2(33)SKJ5. I can SSH into the device via another switch, however I am unable to directly SSH to the device. Has anyone run into this issue? could the IOS be the cause of this?

Hey Chris,
Have you tried pinging the device from your machine?

Airport opens multiple DAAP connections

When I open iTunes on my laptop and my mini-mac, my AEX tower will initiate a DAAP conversation.
This eventually exhausts the sockets my computer can handle.
It also loads the wireless network with garbage packets (ARP and DAAP) that use a considerable amount of BW
Finally my computers will "grind to a halt".
Home Sharing is OFF on my laptop in both iTunes and in System Preferences.
(However, my AppleTV (gen3) will list my laptop iTunes library if iTunes is open)
Within a short time of opening iTunes, there will be about 140 packets (both IPv4 and IPv6) exchanged between the AEX and the computer opening 4 IPv4 DAAP sockets. If I leave iTunes open, another 4 sockets will be opened approximately every minute. As I write this, my system now has 61 DAAP sockets open.   (When I close iTunes the DAAP sockets are closed)
The IP address that initiates the connection is, according to ARP, assigned to the AEX tower. FWIW: this happens in both bridge mode (when DHCP/NAT is not on the AEX) and when DHCP/NAT is on the AEX.
These IP addresses may (probably) have been assigned to a different system on the network at one time.
The AEX tower sends out ARP requests which are not replied to:
11:17:34.727039 ARP, Request who-has 10.0.1.23 tell 10.0.1.23, length 46
11:17:35.057985 ARP, Request who-has 10.0.1.1 tell 10.0.1.23, length 46: NOTE this is the AEX default route
11:17:37.598048 ARP, Request who-has 10.0.1.9 tell 10.0.1.9, length 28
Yet on my laptop, note how many IP addresses are listed as belonging to the AEX.
Some of these have been present for "days".
? (10.0.1.1) at 90:72:40:c:8c:9f on en1 ifscope [ethernet]   <<< This one is valid
? (10.0.1.2) at 0:26:b0:e9:c5:14 on en1 ifscope [ethernet]

? (10.0.1.23) at 90:72:40:c:8c:9f on en1 ifscope [ethernet] <<< not valid
NOTE: ipv6 sockets will also be open, but only 4 of them and these go only to the AppleTV.
The AppleTV does not show up in the ARP table

tcp6       0      0 johns-macbook-pr.daap great-room-apple.54390 ESTABLISHED
I have placed more information on this problem in the AppleTV section, why does iTunes share its library when it is configured Home Sharing OFF?

Can't connect with gftp via ssh

Hello,
I installed openssh on a computer and configured my accsess to it...
I can access it with scp,ssh,sftp from command line with no problem by entering my passphrase and everything runs smoothly...
I want to be able to use gftp to access the files in it, it's a bit more comftarble for me then the command line.
when I try to connect I give gftp the Host, port user and in pass I tried both the user's password and the passphrase and each time I get this reply :
"There was an error initializing a SSH connection with the remote server. The error message from the remote server follows:
ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory"
does anyone knows how to solve this problem?
Thank you,
Grey

Pinging is fine. How would I check the firewalls?
I also noticed this message in the system log:
/usr/libexec/sshd-keygen-wrapper: getnameinfo() only supports IPv4/IPv6. Connection from address family: 5

How to open multiple db connections from one form?

Hello,
We have two different Oracle databases and need to access them (read and write) from the same form. Is there a way to do this, apart from using EXEC_SQL as described in Note 67516.1 ? I could also use db_links and synonyms, but this would add an extra maintenance aspect that I'd like to avoid.
Thanks,
:-Phil

Sorry Phil,
but that's all you got.
