mysql replication


Hello and many thanks in advance for any help offered.

I am trying to setup replication between one master and one slave on freebsd 6.2 and mysql 5.1.12-beta. I know this is not a bsd forum, but I tried the bsd forum and recieved no responses after 4 days so I figured I would give this a shot.

I have changed both my.cnf's on each to reflect their roles.

MASTER

# The following options will be passed to all MySQL clients
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port = 3306
socket = /tmp/mysql.sock
skip-locking
key_buffer = 16M
max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M

# Replication Master Server (default)

log-bin=/var/db/mysql/mysql-bin

innodb_data_home_dir = /var/db/mysql/
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /var/db/mysql/
innodb_log_arch_dir = /var/db/mysql/
innodb_buffer_pool_size = 32M
innodb_additional_mem_pool_size = 2M
innodb_log_file_size = 8M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

[mysqldump]

# Point the following paths to different dedicated disks

Ithought for sure that I have things set up properly, but when trying a dump I recieve:
mysqldump: Error: Binlogging on server not active

So I guess I don't have it correctly configured so that is why I cannot for the life of me find a mysql-bin* anywhere, and why I issue a show master status command and it always returns empty.
I have read many posts, tutorials, examples etc of setting up replication but I seem to be completely stuck. I am afraid I may have messed it up somewhere, but I get no errors on master(but no file). Through the gui mysql administrator front end I can see two databases cluster and cluster replication with a name of binlog_index stored . Not sure what that means.

I do show slave status on the slave and receive:

mysql> show slave status;

So really at this point any help is really appreciated. I will gladly offer more info when asked.
Thank you again.
