From Bugzilla Helper:

When using wget to fetch file over ftp connection and there's a semi intelligent firewall in between wget crashes.

Version-Release number of selected component (if applicable):

Comment 2 Roberto Pallucchini 2005-08-04 03:53:19 EDT
can you tell me another site that i can reproduce this error?
i have tryed people.redhat.com but it work correctly with my system. Do you pass
throught a firewall or other to access internet?

regards
Roberto
