Description Jos Vos 2006-09-24 15:56:32 UTC

Description of problem:
When editting interface info in the graphical interface, the "Netmask" field
only seems to accept a subset of possible netmasks, e.g. it accepts
255.255.255.0, but not 255.255.255.240 or 255.255.255.248.

How reproducable:
Choose "edit" for a network interface in the graphical installer.

Further comments:
Specifying a netmask in the text interface (after the / of in the IP address
field), before the graphical installer starts (after choosing NFS install) works
fine, it accepts all netmasks I tried and it even plain numbers, like "24" or
"28", which is a good thing.

Comment 1 Dave Cantrell 2006-09-25 17:35:39 UTC

This has been fixed in rawhide and will make its way in to the next RHEL5 beta
or alpha or test release.

Netmasks and CIDR-prefixes are accepted for the IPv4 prefix.

Comment 2 Bill Nottingham 2006-09-27 22:08:48 UTC

With rawhide-20060927, this is still broken.

If I enter 172.16.56.125/22, it gives me a netmask of 255.255.63.0 (instead of
255.255.252.0).

If I enter 172.16.56.125/255.255.252.0, it gives me a prefix of /24.

Comment 3 Dave Cantrell 2006-10-02 19:32:43 UTC

CIDR prefix to netmask calculation has been fixed in rawhide.  Thanks.

Comment 4 Bill Nottingham 2006-10-03 16:23:01 UTC

If I enter 172.16.56.125/22, while it does calculate the netmask correctly, it
displays in the 'Network Devices dialog' as 172.16.56.125/24.

Seriously, notting...are you never satisfied?  I fixed this exact problem about
5 minutes ago and committed it to HEAD for rawhide.

It was just a display issue, the internal values were still correct.

BUT, I did just uncover another problem.  The input validation code is borken on
big endian systems.  Working on that.

Comment 6 Dave Cantrell 2006-10-04 17:23:15 UTC

These problems are fixed in today's rawhide (20051004).

Comment 7 Jay Turner 2007-02-14 19:41:17 UTC

Closing out.
