If I hold my mouse cursor over it, it displays "Error connecting to RHN...". If I single or double click on it, I get this error: ===================================================================== An unhandled exception error has occurred. this is most likey a bug. etc etc ===================================================================== Exception type exceptions.IOError Exception Handler Information Traceback (most recent call last): File "/usr/bin/../share/rhn/rhn_applet/rhn_applet.py", line 448, in refresh self.model.refresh(force) File "/usr/bin/../share/rhn/rhn_applet/rhn_applet_model.py", line 264, in refresh self.__rpc_server__.refresh(force) File "/usr/bin/../share/rhn/rhn_applet/rhn_applet_rpc.py", line 84, in refresh status = server.applet.poll_status() File "/usr/lib/python2.2/xmlrpclib.py", line 821, in __call__ return self.__send(self.__name, args) File "/usr/lib/python2.2/site-packages/rhn/rpclib.py", line 126, in _request verbose=self._verbose File "/usr/lib/python2.2/site-packages/rhn/transports.py", line 130, in request headers, fd = req.send_http(host, handler) File "/usr/lib/python2.2/site-packages/rhn/transports.py", line 612, in send_http self._connection.connect() File "/usr/lib/python2.2/site-packages/rhn/connections.py", line 203, in connect response = HTTPConnection.getresponse(self) File "/usr/lib/python2.2/site-packages/rhn/connections.py", line 103, in getresponse response.begin() File "/usr/lib/python2.2/site-packages/rhn/connections.py", line 176, in begin HTTPResponse.begin(self) File "/usr/lib/python2.2/httplib.py", line 269, in begin version, status, reason = self._read_status() File "/usr/lib/python2.2/httplib.py", line 231, in _read_status line = self.fp.readline() IOError: [Errno 104] Connection reset by peer ===================================================================== I also get the standard "Red Hat Network Registration" dialog box: "Your system does not appear to be registered with the Red Hat Network..." etc. etc. and I get to select the "Register with RHN" click box. If I select "Cancel" and then close the "Exception occurred" error box (from above), the rhn icon turns to a blue tick and if I hold my mouse over it I get "Waiting before checking". And then it turns to a grey question mark again. While it is a blue tick, if I right-click it and select "Configuration", it brings up the "Red Hat Network Alert Notification Tool" box. I click "Forward" to "Terms Of Service" and then "Forward" to "Proxy Configuration", I see that my proxy address is in there (I am a networked PC with a RH7.3 proxy server connected to the Internet) but the "Enable HTTP Proxy" box is not ticked. I tick it and then "Forward" and then "Apply" and the dialog closes and the rhn applet icon turns to a double-headed green arrow for a few seconds and then turns to a grey question mark again. If I then repeat the above process and check the "Proxy Configuration" again, it is exactly the same, with the "Enable HTTP Proxy" box un-ticked. When get the standard "Red Hat Network Registration" dialog: "Your system does not appear to be registered with the Red Hat Network..." etc. etc. and I select the "Register with RHN" click box, it takes me through a few steps to "Step 1: Review the Red Hat Privacy Statement", but this never comes up. If I select "Forward" anyway and go through and complete all the forms to "Send Profile Information to Red Hat Network", I get "Problem registering username" and can go no further. It seems that some of these troubles are caused by the inability of my PC to contact the RHN, probably due to the "Enable HTTP Proxy box un-ticked" problem listed above. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. See description 2. 3. Additional info:
You seems to have some networking troubles leading to the problem to connect to the RHN service. Try te following command at the shell prompt, then wait for the escape message hit the return key a could of time and wait for the disconnection: --------------------------- paphio:~ -> telnet www.rhns.redhat.com 443 Trying 66.187.232.100... Connected to www.rhns.redhat.com. Escape character is '^]'. Connection closed by foreign host. paphio:~ -> ------------------------ If you can't get to the "Escape character is..." message then check with your network administrator or ISP you have a problem connecting. If this works try to launch the applet again this may have been a temporary error. Daniel
I have browse, telnet, use news, ftp with no problems, and here is the result of your test: # telnet www.rhns.redhat.com 443 ================================================================ Trying 66.187.232.100... Connected to xmlrpc.rhn.redhat.com (66.187.232.100). Escape character is '^]'. Connection closed by foreign host. ================================================================ The problem has occurred every time that I have tried since installing 9. It worked perfectly with 8.0. It was a fresh install of 9. Does the fact that the "Enable HTTP Proxy" box is being un-ticked mean anything?
"Enable HTTP Proxy" should not be activated unless your network environment requires HTTP or HTTPS connexions to go through a proxy. Ask your network administrator or your ISP about it. The up2date and applet cannot contact the server. That's the reason of the problem. I have no idea why, nor any way to reproduce your problem especially if a direct connection to the server port seems to work. Without a way to reproduce the problem or understand better what is happening in your specific case, there is no way I can guess what is happening in your case. sorry, Daniel
