My Zope v2.6.2 ExternalMethod is giving me an error when I try to open a file for writing.

Error: Module /home/zope/Zope/Extensions/notifyAdt.py, line 88, in seqPut IOError: [Errno 13] Permission denied: '/home/lii/logs/notifyAdtSeq.txt'

That line of code: sf = open(path+seqFile,'w')

(Since this code is also run outside Zope I just use a little file to hold a single value that I want to persist over time - it gets incremented each time.)

I think I've made the file as available as possible. -rwxrwxrwx 1 lii lii 1 Oct 27 13:39 notifyAdtSeq.txt

I'm guessing that the user as whom Zope is running needs to have write access to the directory where the 'open' takes place (but that is just a guess).

It smells like the issue was with restrictive permissions on the higher-level folders. One I loosened that up a little, things started working. thx Tres Seaver wrote:

Shouldn't that be fine?

Try the following:

# su - zope $ touch /home/lii/logs/notifyAdtSeq.txt

If that fails, then I would look at '/home/lii', and ensure that the zope user has execute on that directory (the user needs that permission to be able to traverse a directory).

If that *doesn't* fail, then I am out of ideas. An OS-level permission error is the only thing which explains the traceback you saw.
