Hello all. I'm having some difficulty installing OpenSSH on machines running
RedHat 6.1 and was wondering if anyone has an immediate suggestion (there are
some potentially useful pieces of information that I haven't managed to collect
yet)
I intially installed using the RPMs that are pointed to from www.openssh.com.
Everything went fine, except for a strange problem: X forwarding is subtly
broken. Occasionally, running an X program would produce the following error:
channel 1: istate 4 != open
channel 1: ostate 64 != open
followed by a message that the X connection was broken. GTK+ and Gnome
programs are particularly liable to do this (it was helix-update that drew my
attention to the bug, and which is most reliable in reproducing it)
This seemed odd to me, as OpenSSH works flawlessly (as far as I can tell) on
my usual Debian GNU system. Thinking that maybe it was a bug in the new version
(I use the 1.2 series, as that's the most recent version in .debs), I went to
a great deal of trouble to compile openssl and openssh by hand. The result
was this: EVERY X connection, regardless of program, aborted with the above
errors. This was using openssh source which was, I believe, identical to that
which was used to compile the Debian packages. (which work, as I said,
flawlessly)
I don't think it's a kernel problem; the only remaining explanations that I
can think of are bugs in the libc and compiler, both of which seem a bit
outdated on this system. Does anyone have any clue what could be causing this?
The one piece of information that I don't have and hope to get soon is
whether this affects only the RPM-based client, only the RPM-based server, or
both.
Thanks,
Daniel
