[Yvan Strahm]

Hello,

I get this error:

Traceback (most recent call last):
  File "./map_taxo.py", line 186, in ?
    Download_me(ftp,ftp_dir,file,target)
  File "./map_taxo.py", line 95, in Download_me
    host=ftputil.FTPHost(ftp,user,password)
  File "/usr/lib/python2.4/site-packages/ftputil/ftputil.py", line 136, in

    self._session = self._make_session()

_make_session
    return ftp_error._try_with_oserror(factory, *args, **kwargs)
  File "/usr/lib/python2.4/site-packages/ftputil/ftp_error.py", line 86, in

    raise PermanentError(obj)
ftputil.ftp_error.PermanentError: 530 Sorry, the maximum number clients (32)
from your host are already connected.
Debugging info: ftputil 2.2.3, Python 2.4.3 (linux2)

I have a list of file s to be downloaded and open/close for every items. Is
it the correct way of doing it?

def Download_me(ftp,ftp_dir,file,target):
  user = 'anonymous'
  password = 'anonymous'
  try:
    print "CONNECTING TO "+ ftp + ftp_dir+file+"\n"
    host=ftputil.FTPHost(ftp,user,password)
    host.chdir(ftp_dir+file)
    names=host.listdir(host.curdir)
    for name in names:
      if host.path.isfile(name):
        p="pep"
        m_pep=re.search(p,name)
        if m_pep:
          returned=name
          host.download_if_newer(name,target,'b')
    host.close()
  except:
    print "could not be dowloaded try KAAS"
    ftp='ftp.genome.jp'
    ftp_dir='/pub/kegg/genes/organisms_kaas/'
    print "CONNECTING TO "+ ftp + ftp_dir+file+"\n"
    host=ftputil.FTPHost(ftp,user,password)
    host.chdir(ftp_dir+file)
    names=host.listdir(host.curdir)
    for name in names:
      if host.path.isfile(name):
        p="pep"
        m_pep=re.search(p,name)
        if m_pep:
          returned=name
          host.download_if_newer(name,target,'b')
    host.close()

Thanks for your help.
