           Summary: 2.6.x generates protocol stream error running as server
                    daemon on HP-UX 11.11
           Product: rsync
           Version: 2.6.2
          Platform: PA-RISC
        OS/Version: HP-UX
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: hughw at soco.agilent.com
         QAContact: rsync-qa at samba.org


On HP-UX 11.11, running rsync as an inet daemon, when attempting to contact from
a client workstation or from the local server, the following behavior is seen:

$ /usr/local/bin/rsync262  -an gordie::
emerald
emerald-htdocs
emerald-help
emerald4-htdocs
emerald5-htdocs
emerald6-htdocs
tinman-htdocs
tinman-cgi
tinman-j2ee
tinman-j2ee_903
tinman-forms
tinman-reports
tns

$ /usr/local/bin/rsync262  -an gordie::tns /tmp
rsync: connection unexpectedly closed (24 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(342)

The same error occurs when using 2.6.0 and 2.6.2 as the server; it appears to be
independent of the client rsync revision (we've used both 2.6.2 and 2.4.6; when
the older revision is used to make the connection, the error simply reads
"unexpected EOF in read_timeout").  The error does *not* appear when running the
server at either revision 2.4.6 or 2.5.6.

Most revisions were compiled on HP-UX 11.11 using HP's ANSI C compiler; a TWW
(The Written Word) version also tested was compiled using gcc (not sure which
revision), and delivered as part of their 6.1 toolset revision.

$ /usr/local/bin/rsync  --version
rsync version 2.4.6  protocol version 24
