donk3,

Go to https://rhn.redhat.com/.

They seem to be having ssl problems.
You may also want to check that the server certificate is up to date (I don't know what version of redhat you have). See the website

I'm guessing that you are using Redhat Networks to update your system, right? It would be helpful if you mention this.

Have fun,
chris

Thanks bastard23 . I did forget to put down what exactly caused the error. My version is Red Hat 9 and you probably hit it right on the money.
Thanks Chris
