Description Mark Harig 2002-11-27 00:57:23 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003

Description of problem:
If the user edits /etc/ntp.conf and deletes the text after the keyword
'server', then redhat-config-date either 1) fails silently (when invoked
via the main menu/GUI) or 2) fails with a run-time (Python) stack dump.

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

How reproducible:

Steps to Reproduce:
1. Edit the default /etc/ntp.conf installed with ntp-4.1.1a-9.

2. Find the line with the text 'server  # local clock'

3. Delete the text after the keyword 'server', and then save the
   changes to the file.

4. Select the 'Date & Time' application from the 'System Settings' menu. 
Alternately, run 'redhat-config-date' from a shell prompt.

Actual Results:  When 'Date & Time' is run from the 'System Settings' menu, the
application fails to start and no error message is displayed.

When 'redhat-config-date' is run from a shell prompt, then the following Python
stack dump is displayed:

Traceback (most recent call last):
  File "/usr/share/redhat-config-date/", line 35, in ?
  File "/usr/share/redhat-config-date/", line 176, in __init__
    self.datePage = date_gui.datePage(self.dateBackend)
  File "/usr/share/redhat-config-date/", line 154, in __init__
    ntpServer = mainWindow.dateBackend.getNtpServer()
  File "/usr/share/redhat-config-date/", line 184, in getNtpServer
   self.ntpServer = tokens[1]
IndexError: list index out of range

Expected Results:  Although this was clearly a user error -- the ntp.conf file
is invalid -- redhat-config-date should provide a useful error message.

Additional info:

The code in /usr/share/redhat-config-date/, around line 184,
should likely be modified so that it does not assume that there is a second
token on any line that begins with the keyword 'server'.

This bug was fixed on Nov 15, 2002.  The newest version in Rawhide should fix
this problem.  Thanks for your report.
