When trying to use nntplib to connect to the news server nntp.aioe.org,
a bizarre sequence of events occurs:
1) I import the module, and create an instance, as follows:
s = nntplib.NNTP('nntp.aioe.org')
I get no errors, which leads me to believe all went well. The I try
fetching info on a newsgroup (in this case, comp.lang.python):
s.group('comp.lang.python')
I then get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in<module>
File "/usr/lib/python2.6/nntplib.py", line 345, in group
resp = self.shortcmd('GROUP ' + name)
File "/usr/lib/python2.6/nntplib.py", line 259, in shortcmd
return self.getresp()
File "/usr/lib/python2.6/nntplib.py", line 214, in getresp
resp = self.getline()
File "/usr/lib/python2.6/nntplib.py", line 206, in getline
if not line: raise EOFError
EOFError
This sounds like a time-out.
Running this a *second* time, gives me the following, different error:
Traceback (most recent call last):
File "<stdin>", line 1, in<module>
File "/usr/lib/python2.6/nntplib.py", line 345, in group
resp = self.shortcmd('GROUP ' + name)
File "/usr/lib/python2.6/nntplib.py", line 258, in shortcmd
self.putcmd(line)
File "/usr/lib/python2.6/nntplib.py", line 198, in putcmd
self.putline(line)
File "/usr/lib/python2.6/nntplib.py", line 193, in putline
self.sock.sendall(line)
File "<string>", line 1, in sendall
socket.error: [Errno 32] Broken pipe
When you say "running this", do you mean running a Python program a second time,
or issuing the same command in the interpreter a second time?
For the latter the result would be more or less expected.
After all, you've had an End of File on the connection.
As this is a broken pipe, I reconnect to the server, the same way as
before. When I *then* retrieving the newsgroup's info, I get no errors.
I'm pretty baffled by this. It might be an issue with the server itself,
but still, any input would be very appreciated.
Check if there's any way to specify time-outs.
Check if there's any way to trace the actual commands and responses.
Cheers & hth.,
