MySQL and Postgres users, As a security measure, we are putting the externally available web interfaces for our user based MySQL and Postgres database servers on db.cecs.pdx.edu behind MCECS authentication. This means that users who want to get to those interfaces will have to first authenticate with their MCECS credentials (login/password). For MySQL details, see: [...]
[For database/web developers in MCECS] While direct client access to CAT managed Postgres and MySQL database services are firewalled, the web interfaces for manipulating those databases, phpPgAdmin and phpMyAdmin, have been directly accessible without the need for a VPN. On Wednesday, June 17th, we will be locking down access to these web interfaces as well. [...]
