[issue17967] urllib2.open failed to access a url when a perent directory of the url is permission denied
Senthil Kumaran added the comment: Thanks Zhaoqifa for steps to configure the ftp with acl. I could reproduce it manually and fix it by changes to the urllib.request code. Unfortunately, we dont have rigorous tests for ftp handling in urllib module. That's noted in test_urllib2net module too. This bug is fixed in all branches. -- resolution: - fixed stage: test needed - committed/rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

zhaoqifa added the comment: Sorry for replying so late. 1) Will the above change have any security implications. ---It does not seem to me either. 2) On Ubuntu, I am unable to setup a directory based (ACL'ed) anonymous ftp server. The option is either anonymous from ftp root (/) which will map to my operating system folder (/srv/ftp) or non-anonymous. I wonder how your server is configured to allow anonymous from a particular point onwards. ---I configured proftpd like this: Limit WRITE DIRS DenyAll /Limit Directory /home/* Limit DIRS LIST NLIST AllowAll /Limit /Directory And get message as bellow when login anonymous: lftp perf00:~ cd /home cd: Access failed: 550 /home: No such file or directory lftp perf00:~ cd /home/work cd ok, cwd=/home/work lftp perf00:/home/work cd /home/work/test cd ok, cwd=/home/work/test lftp perf00:/home/work/test ls drwxrwxr-x 8 work work 4096 Jun 15 2011 pb -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Senthil Kumaran added the comment: Hello zhaoqifa, Your suggestion for the solution looks good to me. Instead of cd-ing to each dir, you cd to target dir when ftp url is accessed. Two things to consider. 1) Will the above change have any security implications. It does not seem to me. But I did not write that code originally that way either. 2) On Ubuntu, I am unable to setup a directory based (ACL'ed) anonymous ftp server. The option is either anonymous from ftp root (/) which will map to my operating system folder (/srv/ftp) or non-anonymous.

[issue17967] urllib2.open failed to access a url when a perent directory of the url is permission denied
New submission from zhaoqifa: urllib2.open failed to access a url when a perent directory of the url is permission denied. I had a file in a ftp, the address is like ftp://host/home/work/123.txt which can be access by wget. When I urllib2.open to access the file, it always tell me that: urllib2.URLError: urlopen error ftp error: 550 home: No such file or directory I found that the path /home is denied for anonymouse access but the path /home/work is not. urllib2.open try to call ftp.cwd(home) and then ftp.cwd(work) which failed when ftp.cwd(home). I tried to fix this by changing for dir in self.dirs: self.ftp.cwd(dir) to self.ftp.cwd(os.path.join(*self.dirs) in urllib.py. And it works fine for this situation. -- messages: 189097 nosy: foxkiller priority: normal severity: normal status: open title: urllib2.open failed to access a url when a perent directory of the url is permission denied type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17967 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
