Bug 730744

+++ This bug was initially created as a clone of Bug #665026 +++

Description of problem:
My RHEL5 client is connected to Sat540@RHEL5 using IPv6 and when I try to
rhnreg_ks it with serverURL=https://..., I get traceback saying "Name or service not known".


Version-Release number of selected component (if applicable):
RHN Satellite 5.4.0
rhn-client-tools-0.4.20-46.el5
rhnlib-2.5.22-5.el5


How reproducible:
always on my system


Steps to Reproduce:
1. Have RHEL5 client configured to register to Sat540@RHEL5 using IPv6
   # dig -6 +short ibm-hs22-04.rhts.eng.brq.redhat.com AAAA
   feee:1337::e25f
   # ping6 -c 1 ibm-hs22-04.rhts.eng.brq.redhat.com
   PING ibm-hs22-04.rhts.eng.brq.redhat.com(feee:1337::e25f) 56 data bytes
   64 bytes from feee:1337::e25f: icmp_seq=0 ttl=64 time=0.253 ms
   --- ibm-hs22-04.rhts.eng.brq.redhat.com ping statistics ---
   1 packets transmitted, 1 received, 0% packet loss, time 0ms
   rtt min/avg/max/mdev = 0.253/0.253/0.253/0.000 ms, pipe 2
   # grep serverURL= /etc/sysconfig/rhn/up2date 
   serverURL=https://ibm-hs22-04.rhts.eng.brq.redhat.com/XMLRPC
2. # rhnreg_ks --force --username=admin --password=admin -vvv

I was able to get further (to another error) using this:

After applying that I see what is already reported as bug 665013.

I see same issue on RHEL4 (test05-64.rhndev.redhat.com):

  up2date-4.8.1-33.el4
  rhnlib-2.1.4-7.el4

and on RHEL6 (test02-64.rhndev.redhat.com):

  rhn-client-tools-1.0.0-38.el6.noarch
  rhnlib-2.5.22-9.el6.noarch

Same fix as in comment #1 fixed issue for me and I was able to register (no additional issues popped up on RHEL4, on RHEL6 I had to use --nohardware workaround).

Now on RHEL4 I have updated up2date and rhnlib and I see that problem as well:

up2date-4.9.1-29.el4
rhnlib-2.1.4-17.el4_8.1
