ssh host echo bla | echo bla

[mouring at etoh.eviladmin.org]

Oh a clean (much better this time. =)  install on Solaris it does:

$ ssh localhost echo bla | echo bla
bla
lindstro at localhost's password:
Connection to localhost closed by remote host.

And no jobs are left over.. Which in a lot of respect what I would
expect.

connect to the server, echo 'bla' from the server pass it out stdout.  Hit
the sent '| echo bla'  which is local (because you are not quoting).  It
is lost because the second program disgards all stdin and writes it's
own output.

Not dead sure why Markus was asking what the right behavior should be
since the above is the right behavior (even if I had broken test ssh
servers around the first time. =).

Not sure why yours is background anything.  I can verify this on Linux,
OpenBSD, and Solaris as behavior this way.
