Description Scott Wilburn 2009-08-07 17:28:46 EDT
Description of problem:

ssh requires almost 5 minutes to resolve 'localhost'. Delay does not occur if hostname is given instead, or when pinging localhost.

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

How reproducible:


Steps to Reproduce:
1. ssh localhost
2. ping localhost
Actual results:

ping returns results immediately, ssh takes 5 minutes

Expected results:

ssh localhost is immediate

Additional info:

Contents of /etc/hosts:   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
Comment 1 Scott Wilburn 2009-08-07 18:58:36 EDT
A workaround is to comment out the IPV6 entry in /etc/hosts
Comment 2 Scott Wilburn 2009-08-19 23:14:51 EDT
This problem has been traced to a misconfigured ipv6tables ruleset that was blocking packets to/from localhost. It is not a bug.
