Mysql 4.0.20

Hello,
I have Linux Slackware 10 with mysql 4.0.20 and I'm trying to connect to mysql from another computer on the network, and here's the messagae that comes up
"Host 192.168.... is not allowed to connect to this Mysql Server". Where do I change on mysql server to allow other computers to connect?

Thank you :x :x

have you added a mysql user that is allowed to access your server from the outside world? (grant select on xyz.* to user@yourhost identified by 'yourpass';)
