Last week i was able to build several systems using the red hat satellite server.

I am suing rhel 5.9 and rhel 6.5 for the OS loads and the satellite is on 5.6 of the code. satellite server is running 5.9.

I have been doing this for a long time.
All of a sudden I went to build a system and it hung. said it could not get the packages from the server.

The ip is defined correctly. I am using fixed ip and I hard code it on the boot screen.

All looks OK but when I try to build says it cannot find the satellite server.

So I pressed alt f3 and go the following text.

cannot determine address family of host.mydomain.com
we don't have reverse DNS for IPv6 yet.
transferring http://host.mydomain.com//ks/dist.../images/stage2.img to a fd (I omitted the long path)

and it repeats.
I also tried to use the ip of the satellite server. Same results.

I tried several different network and tried to build 3 other systems all with the same results.

I have been waiting for several hours for RH to get back to me on this but as of yet nothing.

I did google the heck out of it and I found one bug back

https://bugzilla.redhat.com/show_bug.cgi?id=203740

but it has been closed for a long ti,e.

Also I have not updated anything in the env.
One of my systems is even on the same subnet as the satellite server so no proxy or fw involved here.

Any help would be appreciated.

update:
I tried a wget from another working system to see if I could get the ks and put it in the tmp dir. This worked fine.

I am still researching this. No info back from Rh as of yet.
I don't get a lot of hits for this in google. Must not be a common problem.

Interesting thing is if I let the system use a dhcp assigned address and not a fixed one it appears to work. However not all out subnets have dhcp enabled.
Also this was working last Mon/Tues. Checked with network group and nothing changed for using ipv6.

I added the ip of the new client to the host file on the satellite server. That did not change anything.

Once I find out something I'll post back.

here is some config info. As you can see ipv6 is not enabled. changed ip etc for security reasons.

[root@goxsa1209 etc]# lsmod |grep ipv6
ipv6 438113 146 rdma_cm,ib_addr,cnic
xfrm_nalgo 43333 1 ipv6

i disabled the ipv6 in the kernel of the satellite server. same results.

Update:
I finally spoke to RH and it turns out I have uncovered an unknown bug in the satellite server code.
The error I was getting had absolutely nothing to do with the problem I was having thus sending me in the wrong direction for a solution.

IPv6 is not the issue. The issue was in the KS an extra space was put on the line. The build did not like that, however it gave us an error unrelated to this issue.
There are still some outstanding issues and I am working through them with RH.

RH is currently working on open a request to change this.

I will report back on the other issue related to this when I have more info.
