I'm try to setup a database server using mysql, the server starts fine, and I can access it using the built in mysql client via console (adding databases and tables works fine), but the problem is... I always get a connection refused error whenever I access the database outside the built in mysql client (example, if I write a code that connects to mysql). So, I tried execute an nmap command and the only ports open are these ports:
[Code]....
there's no 3306 for mysql... I'm thinking that the firewall is just blocking the port that mysql is using, but my question is, how could the built in client connect to the server if there's no open port for mysql server? Don't clients usually access a servers through ports?

I've setup a CentOS apache web server, and loaded a site onto it. The site previously was functioning under windows xp (before I "stepped in") and wamp. What I did was copy the site in /var/www, reconfigure the httpd.conf (DocumentRoot /var/www/site, etc). Although when I try to open the webpage I get this error: Database Error: Unable to connect to the database:The MySQL adapter "mysql" is not available.
[code]...

I have installed Mysql in Ubuntu 9, for the use of roundcube database.After installing iam getting the error like this
* Stopping MySQL database server mysqld [ OK ]
* Starting MySQL database server mysqld [ OK ]
* Checking for corrupt, not cleanly closed and upgrade needing tables.
So because of this in the roundcube configuration its giving the error message that MYSQL is not installed. So Kindly give me a idea how to solve this.

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).
As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message
Quote:
Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0
If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.
If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.
Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.
Does anybody have an idea how to enforce that the vpn connection is actually used?

What's the best way to establish a VNC connection to a computer located behind a firewall/router, to which you don't have access? I have a home Linux computer on a Comcast connection, which explicitly blocks incoming requests, so I can't hit the IP directly, but I'd like to remote into it from an arbitrary Internet connection. How would I work around this?
I've witnessed some commercial products, such as one employed by Dell tech support, which appears to use a public web server, which you visit from the target computer in order to "expose" it to an incoming VNC connection. Is there anything similar that's free/cheap for personal use?

I have set up a dialup connection using my nokia N70 mobile.. The connection i think, is ok. but when i took a browser-epiphany or mozilla, i cannot open a webpage.. the browser tries to connect but times out.. It seems to be a problem in some settings(firewall, proxy or something) in debian, because im using the same phone to connect in windows XP.. I dont know how and where to check for the settings. code...

I have recently installed Java in my Ubuntu 9.04 environment so that I can teach myself Java. Basic Java programs work, but I am having trouble connecting to a MySQL database. I installed these packages using Synaptic Package Manager.
1.gsfonts-x11
2.java-common
3.odbcinst1debian1
4.sun-java6-bin
5.sun-java6-jdk
6.sun-java6-jre
7.unixodbc
After these packages were installed, I was not sure if I needed to do this, but I downloaded the MySQL connector from MySQL :: MySQL Connectors and installed in a directory called /home/mark/mysql/.
I then did "sudo gedit /etc/environment" and added a CLASSPATH to where I installed the connector:
Code:
I found an example Java program from Using JDBC with MySQL, Getting Started and stripped it down even further to test the MySQL connection.
This is the program I am running:
Code:
Could not find the main class: Jdbctest. Program will exit. I am new to Linux, Ubuntu, Java and MySQL, so I have probably left out something that is very obvious.

I am trying to connect to my mysql database using php but I am getting the error "Fatal error: Call to undefined function mysql_connect()".
I checked phpinfo() and there is no reference to MySQL. I believe this means that my install of PHP doesn't support MySQL. Do I need to uninstall and reinstall with a version of PHP with MySQL support? If so how should I do this and how do I get a version of PHP that supports MySQL?

I have a problem with establishing a VPN connection, it's driving me nuts already. No matter what I try, which packages I (re)install, or how many configuration settings i change.. the result is always the same (see syslog at the end of this post). On the same machine, but on a different harddrive, I have installed Windows 7. The VPN connection works without any problems on this system.
I played already with KNetworkManager, NetworkManagerm, KVpn and so on. Further I re-installed each VPN- and network packages multiple times (eg KNetworkManager, NetworkManager, network-manager-pptp, pptp-linux). Further I tested almost every possible VPN configuration (PAP,CHAP,MSCHAP(v2),EAP,MPPE, stateful encryption, no password, BSD compression)... My syslog is as follow:
Code:
Apr 13 18:15:02 defcon-inc pppd[3721]: LCP: timeout sending Config-Requests
Apr 13 18:15:02 defcon-inc pppd[3721]: Connection terminated.
Apr 13 18:15:02 defcon-inc pptp[3731]: anon log[callmgr_main:pptp_callmgr.c:258]: Closing connection (shutdown)
Apr 13 18:15:02 defcon-inc pptp[3731]: anon log[ctrlp_rep:pptp_ctrl.c:251]: Sent control packet type is 12 'Call-Clear-Request'
Apr 13 18:15:02 defcon-inc pptp[3731]: anon log[call_callback:pptp_callmgr.c:79]: Closing connection (call state)

I recently installed a portable WAMP server on my usb stick. Really nice, I can do some php programming on my girlfriend's windows7 laptop without installing anything on it.I also have a LAMP environnement on my linux computer.When I plug my usb stick on my linux box, I can easily mount -o bind /usbstick/wwwfolder ~/public_html and work on my php script from there.
But my question is, is there a way I could get the database from my usb stick's MySql server, to run on my linux MySql server? So I can modify data base schema from my Linux workstation, doing some INSERTS in some tables, and then plub my usb stick on the laptop and get my up-to-date database running from the portable environnement?I don't know where / how MySql stores its databases. Basically, I want to "mount" the database from the usb stick in my Linux' installed MySql server, without extracting and importing the data, so there is just ONE database used for BOTH environnement.

I posted a thread regarding a CD Base Application. I can run the program, but for some reason It does not seem to work properly.
For some reason in exits the program back to the command prompt. I am using the code from Linux programming 4th edition which you can get it from here...and in the folder ch08/app you will find all you need to create the CD database application.

I'm having problems connecting to the mysql database on my system. I first noticed this when I was trying to set up the program anymeal. I subsequently tried using MySQL Administrator (mysql-admin), but had no luck. It gives my the following feedback:
Code:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Click the 'Ping' button to see if there is a networking problem. I press the ping button, and it seems to connect.

I am facing some strange problem of mysql replication with ssl, my replications which working fine from more than 6 months currently stopped working after i upgrade mysql in to newver version mysql-5.1.41-2, i create new ssl self singed certs but still no sucess, when client try to connect the master using ssl its gives error SSL connection error ERROR 2026 (HY000), with out ssl its working f9.
Platform --> Fedora-11 + mysql-5.1.41-2 (both master/client)
I can seeking the problem on net, and i found the below bugzilla url related to that.
[url]
I read it but not get , either new version support x509 ssl certs or not or either new version support ssl replication or not, here below my server configuration for ssl serts
And for client
Both server and clients certs are signed with same ca but still its currently not working after the mysql upgrade first 5.1.41 and then 5.1.41-2
Either as above bugzilla url, currently mysql support ssl replication or not, or either some need to do special for working with ssl. or i wait for newver version of mysql to fix if its bug or not.

I've down loaded mysql database file and now I'm looking at adding it into a new dedicated server. Should I upload that sql file to the root folder I created for the domain and insert it with shh like that? If not where should I upload this mysql file to insert it to the new database. It's rather large so I have to use SHH Fir example if this is the code,
Code:
mysql -uUSERNAME -pPASSWORD DATABASENAME < MYDATABASE.sql
where is that actual location of MYDATABASE.sql
