Description Tomas Smetana 2008-09-26 05:14:17 EDT
Description of problem:

The tftp server and client package that RHEL distributes doesn't work with IPv6.

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


How reproducible:

Steps to Reproduce:
1. edit /etc/xinet.d/tftp, change flags = IPv4 to flags = IPv6
2. use "curl -6 tftp://serverhostname/filename" to download a file via IPv6
3. try tftp client, but there is no way to specify that IPv6 should be used

Expected results:

We should really upgrade, patch, or switch to a server/client for TFTP that
supports IPv6.
