Subject: rsh does not return errors or at all to stdout (unless buffer is flushed sometimes)
Content-Type: text/plain; charset=us-ascii; format=flowed
Content-Transfer-Encoding: 7bit

I have noticed this problem with rsh in a number of cases. I saw 
reference to the same/similar problem in the MLA to which Corinna 
responded that it would be fixed in inetutils-1.3.2-10. I am using 
inetutils-1.3.2-14. Here are some examples of what seems like odd 
behavior to me:

rsh hostname "ls -l /cygdrive/c/foo"
(returns nothing)

rsh hostname "cd /cygdrive/c/foo; ls -l"
(returns a full or partial directory listing)

rsh hostname "cd /cygdrive/c/foo; ls -l; sleep 3"
(returns the correct directory listing and sleeps)

rsh hostname "ls -l /cygdrive/c/foo; sleep 3"
(returns the correct directory listing and sleeps)

rsh hostname "ls -l /non/existent/dir; sleep 3"
(returns nothing and sleeps)

rsh hostname "cat localdir/foo.c"
(cats the whole file)

rsh hostname "cd /cygdrive/c/foo; cat foo.c"
(cats the whole or partial file, possibly dependent on length?)

rsh hostname "cat /cygdrive/c/foo.c; sleep 3"
(cats the whole file and sleeps)

It looks like rsh doesn't flush the buffer before returning. There are 
times when I try an ls or cat, and I get my prompt back at a random spot 
in the file/listing. And I can't get any errors to come back, such as 
"No such file or directory" when I try to ls a non-existent directory.

I am guessing that this is an rsh problem, as opposed to rshd. Most of 
these tests return the correct output when I try to rsh to hostname 
running cygwin inetd from a solaris machine (except that I still get no 
errors when a file/dir does not exist).

I am not very experienced with gdb, but if anyone can give me pointers 
to debug further they would be greatly appreciated.

TIA,
Peter
