anaconda thinks legal netmasks are invalid
Last modified: 2007-11-30 17:11:41 EST
Description of problem:
When setting up "Network Configuration" in anaconda, it says "You must enter
valid IP information to continue" if you choose a valid netmask such as
Version-Release number of selected component (if applicable):
anaconda in fc6t2
Steps to Reproduce:
1. Do a network install
2. When it first asks you to set up networking (stage1), select DHCP.
3. Go through the various steps until "Network configuration for eth1"
4. For "Netmask" try 255.255.255.128, 255.255.255.192, etc.
"You must enter valid IP information to continue"
It accepts the valid netmask.
If you key in 255.255.255.0 it works fine.
This was done during a network install, but may be valid during a CD install too.
I tried it with IPv6 both enabled/disabled at the stage1 step.
This box has two NICs: eth0 & 1 and it complains in both cases.
It fails in both graphical and text install.
If at the stage1 network setup you manually set the IP (e.g. no DHCP), you can
go through the network setup stage fine (assuming you don't try to change the IP
address in stage2).
Actually, this above statement is INCORRECT, as it does still complain: "If at
the stage1 network setup you manually set the IP (e.g. no DHCP), you can go
through the network setup stage fine (assuming you don't try to change the IP
address in stage2)."
And the step where it does work (stage1, before graphical install begins) is
"Manual TCP/IP Configuration". It's the latter step that fails. Clear enough? ;)
Yes, clear enough. And it's fixed in rawhide.
