Description Travis Gummels 2011-05-04 19:16:44 UTC
Description of problem:

rhn-channel -L should emit cogent error message rather than backtrace when run on a host where the login user does not have RHN Org Admin privs.  User has root access to host, registers system but does not have Org Admin privs in RHN.  The following output is emitted when rhn-channel -L is executed:

[root@rhel6 etc]# rhn-channel -L
Username: mgrondona
Password:
Traceback (most recent call last):

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.
    
    New Contents:
Cause: A bug in rhn-client-tools code.

Consequence: rhn-channel utility would display a traceback in cases the login used did not have permissions to manipulate the system in question.

Fix: The fix was quite easy.

Result: rhn-channel utility now displays a cogent error message in the problematic situations.

Comment 4 Šimon Lukašík 2011-08-10 08:51:08 UTC
Switching to Verified:

Testing procedure:
- rhn-channel -L -- against RHN Satellite
- rhn-channel -L -- against RHN Hosted

Result:
- The error message is omitted against Satellite:
    Error when listing child channels:
    redstone.xmlrpc.XmlRpcFault: No such system - sid = 1000010052
- The error message is ommited against RHN Hosted
    Error when listing child channels: No such system
- Non zero value is returned in both cases

Verified against:
rhn-setup-1.0.0-65.el6.noarch
rhn-client-tools-1.0.0-65.el6.noarch
