Description Bryce Denney 1999-12-09 17:32:14 UTC
I'm having trouble with a RedHat 6.1 network installation on sparc.
I'm using anonymous FTP, and it reads the second stage ramdisk, etc.
but when it gets to the point of reading "hdlist" it dies with a
python exception, saying: 'CWD ' command not understood.

Here is part of the stack trace.  This is typed by hand from another
machine, so it's not complete.

Error: [Errno ftp error] 500 'CWD ': command not understood.

This error is exactly what our FTP server says if you tell it "CWD "
with no directory name.  Other people on newsgroups have noticed the
same problem in sparc installations via FTP.

Workaround for this bug, and others related to 6.1 FTP installation problems:

Boot on the 6.0 install disk, but give it the path to a RedHat 6.1 FTP site!
You get an error about install3.tr not found, and comps has the wrong
version number, but you can go ahead with the menu interface and install
it anyway.  Ugly, but it works.

I verified that ProFTPD upto last version 1.2.0pre9 returns:
500 'CWD ' is an unknown command.
wu-ftpd version 2.4.2 shows response to "pwd"
550 /home/ftp: No such file or directory.
and to "pwd " (with space)
500 'CWD ': command not understood.
wu-ftpd version 2.5 accepts "pwd", but shows response to "pwd "
500 'CWD ': command not understood.
wu-ftpd 2.6, Microsoft FTP service 3.0, 4.0, 5.0 accepts both "pwd" and "pwd "
By recommendation is to avoid semding cwd without directory name.

This issue is resolved in the latest installer from RawHide.
