php/mysql

I don't know where the error lays, in php, mysql or red hat 8. But, I can't get my databased php-apps to work. I am trying to run: apache_1.3.27 php-4.2.3 mysql-3.23.53 redhat 8.0 What happens is that apache and php work nicely, but my apps cannot connect to mysql. In IRM I get can not connect to database, and in phpgroupware I get the the thing up and running, but can't add anything to the tables. E.g. I can't add a to-do even if the routine runs normally, nothing is added in the db table. I saw a suggestion on a mysql mail list suggesting symlinking mysql.sock to /tmp but that does no difference. Any suggestions? /Martin S.
