[rhelv6-list] error communicating with RHN

[Weiergräber, Oliver H.]

In the meantime I got a little closer to the root of the problem. First of all, the issue is temporary, and package lists on RHN are updated with the next successful connection. So in this respect, there are no consequences to deal with.
However, in subsequent attempts to directly install packages avilable on the web via rpm, I sometimes saw name resolution failures. When this happened, simply repeating the command was always successful! I'm on a private network using fixed IP addresses, and the DNS server entry is supposed to be the address of the router, which is supposed to handle things on its own. I never observed a problem like this on any of my machines, with RHEL or CentOS < 6.2, with the very same network setup.
So the question arises whether anything has canged in 6.2 which could make DNS resolution more "unstable". Maybe just a different (too short) timeout until name resolution is considered failed...?

Any ideas?
Oliver

Subject: [rhelv6-list] error communicating with RHN

Hello,

following a fresh default installation of RHEL 6.2 (client) I just ran "yum update" for the first time.
The system successfully downloadad and installed some 30 updates, but the processed finished with this message:

There was an error communicating with RHN.
Package profile information could not be sent.
Error communicating with server. The message was:
Name or service not known
Installed products updated.

Does this require attention, or does it just indicate a temporary problem on the Redhat server? Is sending of "package profile information" after installation of updates an essential operation? If so, should this information be sent manually in this case?
During installation, the system was registered with RHN without any problem, and profiles have been transferred at that time.

Best regards,
Oliver
