  I've CC-ed the list so this gets archived.

This is what I was saying before 
.   The binary packages provided by RedHat have many things compiled 
against them.  If you don't follow the upgrade path recommended by 
RedHat (i.e. they keep everything at 0.9.6b as an internal version 
number) then you run into instances like this.

This is a security precaution.  If it would happen that someone replaced 
the libraries of OpenSSL with a hacked version or a compromised 
replacement it would be caught.  Obviously not a foolproof method but 
is definitely a help.

RPM isn't always clear with its dependencies.  When dealing with RedHat 
there's 5 packages for OpenSSH - openssh, openssh-server, 
openssh-client, openssh-askpass and openssh-askpass-gnome.  You need to 
upgrade all of those at the same time.

What you should do is go to Rawhide (my favorite mirror is and go to the SRPMS tree 
( and get 
openssh-3.5p1-6.src.rpm.  This is the source RPM for RedHat's openssh 
packages.  If you're on RH8.0 you'll want to do an 'rpmbuild --rebuild 
openssh-3.5p1-6.src.rpm'.  This will make the 5 packages you need in 
/usr/src/redhat/RPMS/i386.  You can then install them from there and 
should resolve your depedences.

On a side note, while I use many RedHat servers in a production release, 
I would not consider 8.0 "production ready" just yet.  They're working 
out a lot of bugs that'll be fixed in 8.1.

If you continue to have problems, please e-mail me back but please make 
sure to CC openssh-unix-dev at so other can benefit.  Thanks.
