           Summary: ssh fails with -C flag when connecting to a compression
                    disabled server
           Product: Portable OpenSSH
           Version: -current
          Platform: ix86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: wallp at earthlink.net


If using ssh or scp with the following flags -C the process will die with
"no matching comp found: client zlib server none"
if the server has Compression disabled.
The output with -v is as follows.

OpenSSH_3.4p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f

Some older systems. Notably Linux with a 2.2 kernel cannot have Privledge User
support and Compression enabled at the same time. Atleast on my system it cannot.
