Description Alexandre Oliva 2008-05-04 06:38:59 EDT
Description of problem:
For some reason, as of recently, I had to set a lower-than-1500 mtu on one of my
notebooks for reliable network operation.  This has been easy to do with config
files, but it proved to be challenging to get Fedora 9-Preview installed on this
notebook with kickstart, for the mtu argument appears to be ignored for install
time.  As a result, the machine ends up unable to access the nfs-mounted install
media: the TCP connections used to implement NFS break unless I force the TCP
MSS to a lower value on the server, emulating to some extent the effects of
setting the MTU on the installing client.  I could verify during installation
that the dhcp-configured ethernet interface had MTU set to the default value,
rather than to the one I'd specified.

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

How reproducible:
Every time

Steps to Reproduce:
1.Boot up with e.g. mtu=500
2.Check that the setting made to the interface

Actual results:
It doesn't

Expected results:
It should

Is this still a problem in the final release of F9?

'fraid so.
Comment 4 David Cantrell 2008-08-01 22:00:26 EDT
This should be working in recent rawhide trees.
