UnknownHostException in IDEA

Hi altogether,

I always get an UnknownHostException when trying to update via CVS or update the plugin list in IDEA.
This happens either when I use JDK 1.4 or with JDK 1.5
It also happens in IDEA 4.5 and IDEA 5.0. This bug report exactly describes my problem:


What can I do?
I already cleared my IDEA Home directory completely, cause I thought that could be the problem but it didn't help.

My system: Debian Linux Unstable(Sid), Kernel 2.6.11

I also couldn't find this "networkaddress.cache.negative.ttl " setting anywhere in the IDEA Home directory, which
is mentioned in the linked post.

So, now I found this "networkaddress.cache.negative.ttl" setting in jre/lib/security/java.security.
I changed in in my JDK 1.4 and JDK 1.5 to "0" and then started IDEA4.5 and IDEA5 with JDK 1.4 and JDK 1.5, but still - the same error.

Can anybody help me out?
