Summary: Problem with ftplib on HP-UX11i

Initial Comment:
The following code fails on Python 2.3 (and 2.3.1).



import ftplib

f = ftplib.FTP()

f.connect('hostname', 21)



this raises:



socket.gaierror: (8, 'host nor service provided, or not 

known')



In FTP.connect() it is the call to socket.getaddrinfo() 

that is raising the exception.



The same code works OK on Python 2.2.1



If I pass an IP address instead of a hostname, the code 

runs OK on Python 2.3

Hm. What's the actual hostname you're trying? I can't get

this failure on HP/UX 11.11, using the HP testdrive box. 



Are you using NIS or some other non-standard method of

hostname lookup? The problem is that there's a fair bit

changed between 2.2 and 2.3's socket module (there was 71

different checkins).

Apologies for not being clear.



I actually used the real hostname (in quotes) of a workstation 

on our local network in place of 'hostname'.



If I use 'localhost' or the hostname of the workstation the 

application is running on, I don't get the error.



If I use the hostname of any other workstation on the local 

network, I do get the error.



Running exactly the same code on Python 2.2.1 works OK for 

all hostnames.

Using the HP testdrive system

HP-UX spe169 B.11.11 U 9000/800 1939057856 unlimited-user

license



I did the following with 2.3.2c1:

>>> import ftplib

>>> f = ftplib.FTP()

>>> f.connect('localhost', 21)

'220 spe169.testdrive.hp.com FTP server (Version

1.1.214.4(PHNE_27765) Wed Sep  4 05:59:34 GMT 2002) ready.'

>>> 



Ah. In your example, you have 'hostname'. Is that

_literally_ what you typed? If so, it's looking for a

machine called 'hostname'. I tried that, and got the same

error you got. 



Try it without the single quotes around 'hostname'.

Hm. I'm obviously having reading difficulties. There's

obviously something else going on entirely. Damn. I will try

to grab some time on one of the HP test boxes to see if I

can figure what's going on...

Did the workaround fix the problem? I'm not sure why it'd

work for 2.3 and not 2.3.1, unless 2.3.1's script was

generated with a newer version of autoconf - aha. Yes, it was. 

If you could check if the fix in 

https://sourceforge.net/tracker/?func=detail&atid=105470&aid=811160&group_id=5470

"makes it all better", that would be great. Put aclocal.m4

alongside configure &c, re-run autoconf, then ./configure ; make

I had already applied the workaround to my 2.3.1 build.



I don't think configure was broken with Python 2.3 - and it 

was with 2.3 that I first noticed the problem.

Hm. I wonder if this is related to the configure broken-ness.

Can you apply the workaround from

http://www.python.org/2.3.1/bugs.html and see if the problem

is fixed?
