[root@turmoil /root]# dd if=/dev/zero bs=1k count=100 | wc
100+0 records in
100+0 records out

[root@turmoil /root]# ssh localhost dd if=/dev/zero bs=1k count=100 | wc

Um.. (this was from a tip-off on linux-kernel)

Comment 1 Tim Waugh 2001-01-18 16:47:27 UTC
Oh yeah, this is with:


Comment 2 Glen Foster 2001-01-18 21:24:50 UTC
This defect is considered MUST-FIX for Florence Gold release

Comment 3 Pekka Savola 2001-01-20 08:03:33 UTC
This is caused by the same thing as #21607.

This can be solved by reverting a fix or upgrading to latest snapshots, but 
the other problem with hanging connections (#19837) (sleep10& exit; service httpd restart, etc.)
will then come up.

It's one or the other, unless someone figures a way to fix this properly :-(.  There's info about these
issues in the reports I think, as well as current OpenSSH CVS TODO list.

Comment 5 Pekka Savola 2001-01-23 19:07:50 UTC
Note: there's a workaround for bash by Damien Miller for #19837:

shopt -s huponexit

Comment 6 Brian Brock 2001-02-01 00:22:37 UTC
In addition to the above, I'm getting the following output with
openssh-2.3.0p1-14 (logged in as user test across the network):

[test@localhost test]$ ssh localhost dd if=/dev/zero bs=1k count=100 | wc
select: Bad file descriptor
      0       0       0

The complaint about select isn't listed above

Comment 7 Pekka Savola 2001-02-02 23:53:06 UTC
Brock, do you have  a funky .bashrc or .bash_profile which prints out stuff when you log in?

Or anything that'd generate output in stderr?

Comment 8 Nalin Dahyabhai 2001-02-20 22:58:58 UTC
2.5.1p1 should show up in Raw Hide soon.

Comment 9 Brian Brock 2001-02-21 17:51:27 UTC
No, the user test doesn't have anything unusual in .bashrc, .bash_profile, or
any similar startup files.  In fact, they're unmodified from a stock install, so
they should be identical to the copies in /etc/skel (the user test was created
after system installation of the beta.

Double-checking the .bashrc and other files (by sourcing them as the logged-in
user) didn't reveal any output to stderr.  

I'm going to begin re-testing with the latest tree (qa0221.0) today, which
includes the new openssh-2.5.1p1-1.

Comment 10 Nalin Dahyabhai 2001-02-22 22:17:34 UTC
I highly suspect login scriptlet wackiness is to blame here.  The
closing-too-soon problem in 2.3.0p1 is correctly reverted in 2.5.1p1, but we get
the hang-on-exit (which affects rsh, too) when we do that.

Comment 11 Nalin Dahyabhai 2001-02-28 22:35:34 UTC
I'm beginning to suspect that this is endemic to the rsh and friends work,
because the hang appears both on an OpenBSD server running OpenSSH 2.5.1, and on
a Linux box using regular unencrypted rsh.

Comment 13 Tomas Mraz 2005-02-03 09:01:54 UTC
This is fixed as the patch that caused this regression was removed
long ago.
