https://bugzilla.mindrot.org/show_bug.cgi?id=2149

            Bug ID: 2149
           Summary: ssh client shows connection closed by remote host
           Product: Portable OpenSSH
           Version: 6.0p1
          Hardware: PPC
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: sshd
          Assignee: unassigned-bugs at mindrot.org
          Reporter: zq_fan at 163.com

sshd server environment: montavista linux with openssh 6.0(openssl
0.9.8)
when i connect the sshd server, it prints "connection closed by remote
host". When i login the system from com port, there are many "sshd
-R"
processes which process state is D state(means blocked in the kernel
state).
when i read the code: when client prints "connection closed by remote
host", it means client can not read the version string from the remote
server. The read function returns an EPIPE errorcode.
Is this a known problem? how can i fix it?

--- Comment #1 from Damien Miller <djm at mindrot.org> ---
processes stuck in 'D' state are often the result of waiting for an
unreachable NFS server or kernel bugs. If you are not using NFS then
check dmesg for signs of problems.

In any case, we'll need a full debug trace from both the client and the
server to debug this.
