IIS FTP Server Does Not Use Continuation Character CorrectlyLast reviewed: April 29, 1997Article ID: Q154962 |
The information in this article applies to:
SYMPTOMSThe FTP service in Internet Information Server versions 1.0 and 2.0 with directory annotation enabled uses a space for a continuation character in a multi-line response rather than a minus sign (-) as per RFC 959. Notice the correct behavior below with the Microsoft Windows NT FTP Server. The 230 line is followed immediately by the continuation character (-): 230------------------------------------------------------------------------ and here with the IIS FTP Server it is incorrect 230 ----------------------------------------------------------------------- This can create problems for auto connecting ftp clients.
STATUSMicrosoft has confirmed this to be a problem in Microsoft Internet Information Server versions 1.0 and 2.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
MORE INFORMATIONAccording to J. Postel & J. Reynolds, RFC 959 - File Transfer Protocol (1985), page 35:
"Thus the format for multi-line replies is that the first line will begin with the exact required reply code, followed immediately by a Hyphen, "-" (also known as Minus), followed by text. The last line will begin with the same code, followed immediately by Space <SP>, optionally some text, and the Telnet end-of-line code." |
