Bug 167902 – PORTAGE_BINHOST fails if PASV not allowed

• Status: RESOLVED FIXED
• Product: Portage Development

[Description edoceo 2007-02-21 18:56:01 UTC]

grep BINHOST /etc/make.conf
PORTAGE_BINHOST="ftp://portage:@c.edoceo.com/"

But my FTP server doesn't allow PASV so then when the Python ftplib issues PASV it chokes and dies :(

Here's the spew:
curo etc # emerge -pvuDN world

These are the packages that would be merged, in order:

Calculating world dependencies  .Fetching binary packages info...
 * No password provided for username 'anonymous'

Traceback (most recent call last):

    self.retrlines(cmd, files.append)
  File "/usr/lib/python2.4/ftplib.py", line 396, in retrlines
    conn = self.transfercmd(cmd)
  File "/usr/lib/python2.4/ftplib.py", line 345, in transfercmd
    return self.ntransfercmd(cmd, rest)[0]
  File "/usr/lib/python2.4/ftplib.py", line 321, in ntransfercmd
    host, port = self.makepasv()
  File "/usr/lib/python2.4/ftplib.py", line 299, in makepasv
    host, port = parse227(self.sendcmd('PASV'))
  File "/usr/lib/python2.4/ftplib.py", line 241, in sendcmd
    return self.getresp()
  File "/usr/lib/python2.4/ftplib.py", line 216, in getresp
    raise error_perm, resp
ftplib.error_perm: 500 Unknown command

NOTE:
  host, port = parse227(self.sendcmd('PASV'))

If I enable PASV on my FTP server it's OK.  I would like Portage to work on both passive and non-passive FTP servers.

I also got a very similar error due to a bad file in the ftp server's portage directory.  I used the tail command on the srever's messages file to detect the error when a client tried emerge -gk pkgname.  Then traced it to ut2004 data file size problem.  So I removed that file and everything worked.  It is odd tha t the ut2004 file error would come up when I was emerging an update to gzip.  Hmm.  A nicer error from emerge would be desirable.

This should be fixed now, since we no longer use ftplib. However, with ftp, you may encounter bug 350139.
