Hi Toshio,

Could you please post some steps to reproduce the error?
Also what package version do you have installed?
rpm -q rhn-check rhn-client-tools rhn-setup rhn-setup-gnome yum-rhn-plugin rhnlib

It seems to work fine on my test system.

Regards,
Michael

Apologies, after further looking into this, the timeout parameter problem is due to an older version of the up2dateAuth.py file from rhn-client-tools that a prior admin had checked into our sytems as a hotfix.  So the timeout problem is bogus.

For the except e: => except Exception, e: change that does address a valid bug in the code.  It only triggers if an exception is actually raised in the try: block, though:

$ python2
>>> try:
...  pass
... except e:
... pass
>>>
>>> try:
...  raise ValueError
... except e:
...  pass
... 
Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
NameError: name 'e' is not defined

The token after except needs to be the name of an exception, not a variable to store the exception in.  Since we're trying to catch all exceptions, use "Exception" there to catch any exception.

Fixed in spacewalk master by
commit 60cf0271cc8a32b709b6f66161938fa03bede4d4
    1018929 - removed redundant exception
    both sections just re-raise exception as RepoError

Fix looks good to me.

Reproducer with yum-rhn-plugin-0.9.1-50.el6.noarch

I can't find correctly steps to reproduce. I edit code to get a traceback. 

# vim /usr/share/yum-plugins/rhnplugin.py 
try:
   li = up2dateAuth.getLoginInfo(timeout=self.timeout)
--->
   # create some other traceback: IndexError..
   test = []
   print test[1]
--->
   except up2dateErrors.RhnServerException, e:
      raise yum.Errors.RepoError(unicode(e)), None, sys.exc_info()[2]
   except e:
     raise yum.Errors.RepoError(unicode(e)), None, sys.exc_info()[2]
