Description Arenas Belon, Carlo Marcelo 2003-04-08 10:34:30 EDT
Description of problem:
an Exception of type SSL.SysCallError was received on the applet and reported as
a bug with a question mark icon

Version-Release number of selected component (if applicable):

How reproducible:
probably related to some maintenance on the RHN servers, i could try to block
the RHN servers and see if i can reproduce the error, but my guess is that i
could reproduce it re routing the RHN servers to a server not listening or
rejecting XMLRPC over HTTPS connections

Actual results:
Exception type SSL.SysCallError

Expected results:
the usual "ok" icon

Additional info:
the problem was gone once i "reconfigure" the rhn-applet
Comment 1 Arenas Belon, Carlo Marcelo 2003-04-08 11:17:33 EDT
interesting also that just after the problem i got a report that my kernel was
not up2date as reported on bug #84757.

both problems disapeered once i right click on the applet and went thru the
"configure" process again

couldn't add this same comment to ticket #84757 tough as the ticket broken as
explained on bug #87920
Comment 2 Daniel Veillard 2003-04-08 12:41:04 EDT
Well it's an error connecting to the server, I doubt it's a registration
based problem. Are you using a free RHN slot or a paid one ? Anyway
I tried to make sure the exception will be properly caught in future
version of the rhn-applet package.

Comment 3 Arenas Belon, Carlo Marcelo 2003-04-08 13:01:36 EDT
i am using a paid RHN slot (uuid=6931413a-6673-11d7-80a0-00d059543bd1).

after giving it some more thought, i think the problem should maybe better be
handled on the SSL.py package for rhnlib 1.0 where there is no exception
handling an SSL.SysCallError on the write method as it is currently being
handled on the read method, otherwise the SSL subsystem wouldn't give consistent

the problem couldn't be replicated just trying to fool rhnsd or blocking access
to the RHN server as the problem was presented while writing to the established
and authenticated SSL connection
Comment 4 Warren Togami 2003-04-11 18:20:46 EDT
This same error happened to me on Shrike.  I am a paid RHN customer.
Comment 5 Daniel Veillard 2003-04-11 18:29:42 EDT
The applet (nor the SSL layer) do not catch up all the connection errors,
however it tries to recover from them. Did the icon turned grey with an
interrogation mark (i.e. it got stuck in the error state) or did it indicated
a connection error (double arrow on grey background crossed with a red strike) ?
In the last case it will retry the connection automatically until it succeeds
and the error message is then purely informative.

Comment 6 Arenas Belon, Carlo Marcelo 2003-04-11 20:06:15 EDT
as i reported initially i got an interrogation mark (AKA question mark), a gray
one indeed.
