Re: Security Question
If it's a DoS attack then perhaps you should be speaking to your ISP and getting that resolved rather than trying to work around the problem on your side of things! Having said that, you could possibly impose host level restrictions in MySQL, but that could be a lot of work to modify your existing user base, especially since you'd need to gather all your remote host information first, and then do all the updates. Cheers. Armando J.R. Bullington wrote: Hi All -- I have been a member of this list for a while but I actually have a question that I can't answer.

Anything I can do extra via MySQL that will keep this person away, or perhaps free up the server? I would rather not increase the max_conn_allowed var as it's already at 800 (more than I need).

RE: ASP Connection to Mysql fails
Paul,
Interesting: I just tested your DSN-Less connection info. (including
port 3307) from my web server to another machine running mysql and it
connected fine - but only the first time. I used the IP address for my
SERVER variable. Then I changed it to the FQDN and it failed with the
same message you're getting. I tried setting up an entry in my hosts
file to specify the FQDN of the remote machine along with its associated
IP address and it still fails. Then I changed the SERVER variable back
to the IP address, and now it won't connect at all again.
Restart the MySQL service on the db machine, fails. Restart WWW service
on webserver, fails. Restart IIS Admin on webserver, fails!
Try from the ODBC administrator on the webserver using both IP and FQDN,
connects every time no problem, DSN-less connection refuses to work at
all.
I'm going to dig into this a bit tomorrow with a few people at work and
see what I can come up with and will let you know. This is starting to
bug me too...

Armando:
I tried the fully qualified domain name 'computer.domain.root', I also
tried the IP address. Both worked on the odbc test, but not on the
connect string.
I have already gone the DSN route and it works, but it bugs me that the
DSNless method doesn't work.
My current hypothesis is that the odbc driver is confusing (or
ignoring)either the ip address or port # for the local mysql DB with
what I want for the remote.

Subject: RE: ASP Connection to Mysql fails
Paul, when you say SERVER=myserver.com, are you specifying the FQDN
name? ie; thatcomputer.thatdomain.com
I know you mentioned you use the same settings in your ASP script as you
did in the ODBC data source test but if you didn't specify the FQDN, try
it and see what happens.
Failing that, try setting up a System DSN in your ODBC Data Sources
(since you said you could connect that way) and once the DSN is setup,
try setting your ASP connection string to connect to the remote server
using the DSN name rather than a DSN-less connection string and see what
happens there as well. Cheers.

Subject: ASP Connection to Mysql fails
I have an ASP application running on a server with a mysql DB,
everything works great. I connect using localhost, no problems.
I have a second mysql DB on another server. I connect to it via the odbc
Data Source Administrator from the web server with no problems.
When I try to connect from an ASP script from the web server using the
following;
=
Set connMailServer = Server.CreateObject("ADODB.Connection")
ConnectString = "DRIVER={MySQL ODBC 3.51 Driver}; SERVER=myserver.com;
USER=root; PASSWORD=rootPW; DATABASE=myDB; PORT:3307; OPTION=35;"
IntDebug=connMailServer.Open(ConnectString)
=
The server, user, password, database and port are what I used in the
odbc Data Source Administrator. Remember I can connect to my local DB
from ASP.
I receive the following error;
==
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on 'myserver.com'
(10061)
=
The environment is w2k server on both computers. The MYSql version on
remote server is 4.0.17.
I'm so confused...

Installing multiple versions of mysql
I am currently trying to install mysql on a linux machine that already has mysql running. I went into the safe_mysqld script and modified the tcp port to point to 3308 and the mysql.sock file to point to /tmp/tmp/mysql.sock. I was able to get this to work with one of the newer versions of mysql 3.23.40, by doing the above and using the following config command: ./configure \ --with-tcp-port=3308\ --with-unix-socket-path=/tmp/tmp/mysql.sock\ --prefix=/usr/mysql The funny thing is, a message pops up saying that I didn't need to configure the version I had. However, safe_mysqld wasn't working otherwise. Anyway, I couldn't use this version of mysql with a php build procedure I was using, so I used an older mysql version 3.22.32. Any time I try the above (and I use a different port number even from the one above, which I deleted and killed anyway), the final message always states (mysqld daemon ended). Any clues would be greatly appreciated. Thanks in advance. Armando __ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!
