>Description:
Since 4.1R, fetch requires MTDM supports to ftpd.
Because in /usr/src/lib/libfetch/ftp.c:

static int
_ftp_stat(int cd, char *file, struct url_stat *us)
{
                ......
   if ((e = _ftp_cmd(cd, "MDTM %s", s)) != FTP_FILE_STATUS) {
	_ftp_seterr(e);
	return -1; /* HERE!! */
   }
                ......
}

So if ftpd does not support MTDM, then connection will be
closed.

MTDM is NOT RFC yet.
And some ftpds do NOT support MTDM.
Such as Solaris2.8's one, and MS ftpd version4.
This means fetch(1) on 4.1R can not talk them!


>How-To-Repeat:

>Fix:
Sorry, I can't make patch.

I think

   if ((e = _ftp_cmd(cd, "MDTM %s", s)) != FTP_FILE_STATUS) {
	/* _ftp_seterr(e);
	return -1;  */
             ln = "000000000000"; /* or more better value */
   }

may be work.... Is this correct?
