svn: Can't connect to host 'example host address': Permission denied

Hi,

I am using rapid svn using tortoise svn in linux fedora 6.0. I've installed drupal 5.16 and installed the modules for subversion.

I've got an error while fetch the svn address like the below

The repository at svn://example host name/example project/Projectsource/trunk could not be accessed. Error message from 'svn info':

svn: Can't connect to host 'example host name': Permission denied

I'm a new bie... can any one help me regarding this problem??? Thank you...
