Description Ricardo Rodriguez 2016-05-17 14:40:22 UTC
Description of problem: ipcalc has no output as fedora or debian because it is in a package apart from the initscript and in redhat/centos it is inside of the initscript and IPv6 validation fails in ipcalc redhat/centos.

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

How reproducible: 

Steps to Reproduce:
1. install from the beginning use ipcalc 
2. ipcalc = no result
3. ipcalc -6 -p 2001:13f0::1/32 = ipcalc: unable to show setting for IPv6

Actual results:

ipcalc does not show any output.
ipcalc does not show any output.
ipcalc -6 -p 2001:13f0::1/32
ipcalc: unable to show setting for IPv6

Expected results:

in fedora 23:
Address space:  Private Use
Address class:  Class C
Netmask: = 24

Hosts/Net:      254

ipcalc -6 -p 2001:13f0::1/32

in debian:

Address:          11000000.10101000.00000001. 00000001
Netmask: = 24   11111111.11111111.11111111. 00000000
Wildcard:            00000000.00000000.00000000. 11111111

The ipcalc from initscripts was only meant to be used inside scripts, so the fancy output for such use cases does not make sense. In the fedora we have decided to split ipcalc to its own project and the current developer introduced couple of new nice features. I would rather play it safe here and do not backport those features to rhel.

But the ipcalc -6 -p 2001:13f0::1/32 look as a bug and we should fix it.

Comment 5 Lukáš Nykrýn 2016-06-13 13:29:13 UTC
Hmm, it is not a bug, we just don't support that :-(
    if (familyIPv6 &&
        (showBroadcast || showNetmask || showNetwork || showPrefix)) {
        if (!beSilent) {
            fprintf(stderr, "ipcalc: unable to show setting for IPv6\n");
        return 1;

To be honest I don't want to implement this just for rhel7, since we will have Nikos' ipcalc in the future. So unless you have strong objection I will close this as wontfix, since initscripts are now mostly in maintanance mode and we don't implement new features. Or someone sends a patch :-)

Comment 6 Ricardo Rodriguez 2016-06-15 12:29:40 UTC
Ok, this ipcalc package for Redhat/centos/scientific will be available in 3, 6, 9 or 12 months from now? 

My dear Lukas you can mark the bug as a wontfix case.
