Got "Broken pipe" message during FTP session w/FTP script

Got "Broken pipe" message during FTP session w/FTP script

Post by Ming Fu » Fri, 20 Dec 1996 04:00:00


     I have a problem with the current FTP script that I am using:
   Here it is:


cat <<END
ftp -n -v << EOF
open "host"
user "user" "password" "account"
lcd local/directory

sed -e 's/.*/get &/' filelist

cat <<END


  What this script is supposed to do is to continuously "get file#.tar.Z."
from the "filelist" in one FTP command.  There are over 100 FILES
to get and this entire process consumes around 30 minutes.

    The MAJOR PROBLEM with this script is when I added the "-v" (verbose)
 command in the initial FTP command.  The reason I added the "-v" command
 was to get some FEEDBACK from the remote FTP server.  I'd say about
 90 percent of the time I get this ERROR displayed on my screen:

ftp: accept: Protocol error
426 Data connection: Broken pipe.
421 Service not available, remote server has closed connection
Not connected.
Not connected.
Not connected.
Not connected.

    After this message, I was KICKED OUT of my FTP site and only about
  25 percent of the files are TRANSFERRED OVER.

    The FUNNY THING is that when I GET RID OF the "-v" command in the  
  initial FTP script, EVERYTHING works fine (the script works 100  
  percent of the time).  All my files are safely
  transferred over BUT I want some sort of INDICATION from the remote
  server on what files are being transferred DISPLAYED on my screen.

  Any Suggestions ???

1. FTP to Linux yields "BROKEN PIPE"


I'm running kernel 1.1.2 with the Slackware 1.1 distribution... and trying
to FTP to this Linux machine from a DOS box running NCSA telnet/FTP
(that would be version TEL2307b.ZIP).  What I see happen, is the entire
file gets FTP'd and then I get the message "Broken Pipe" from NCSA FTP...
and it starts sending the whole file over again.  This repeats once or
twice and then the transfer hangs.

FTPing from the Linux machine to the DOS machine works like a charm...

The NCSA stuff is running on top of Crynwr packet driver(Ver 11)
and NE2100 clone.

TELNETs to the Linux box seem to work flawlessly also.

I realize my kernel is quite a few patches behind current-- but everything
has been working so nicely for me I didn't want to break it :-)  Maybe
I just need a kernel upgrade to fix this-- but I'd like good evidence
before doing it.

Any other ideas where I should look to solve this problem ?
