User’s Guide
If the target Internet address is not in /etc/hosts (or the NIS equivalent), then the
host does not know about your target. The VxWorks boot program receives an
error message from the host:
host name for your address unknown
Error loading file: status = 0x320001.
0x32 is the VxWorks module number for hostLib 50 (decimal). The digit “1”
corresponds to S_hostLib_UNKNOWN_HOST. See the errnoLib reference manual
entry for a discussion of VxWorks error status values.
■
Verify host file permissions.
The target name must be listed in either of the files userHomeDir/.rhosts or
/etc/hosts.equiv. The target user name can be any user on the host, but do not use
the user name root —special rules often apply to it, and circumventing them
creates security problems on your host.
Make sure that the user name you are using on the target has access to the host
files. To verify that the user name has permission to read the vxWorks file, try
logging in on the host with the target user name and accessing the file (for instance,
with the UNIX size command). This is essentially what the target does when it
boots.
If you have trouble with access permissions, you might try using FTP (File Transfer
Protocol) instead of relying on RSH (remote shell). Normally, if no password is
specified in the boot parameters, the VxWorks object module is loaded using the
RSH service. However, if a password is specified, FTP is used. Sometimes FTP is
easier because you specify the password explicitly, instead of relying on the
configuration files on the host. Also, some non-UNIX systems do not support RSH,
in which case you must use FTP. Another possibility is to try booting using BOOTP
and TFTP; see VxWorks Network Programmer’s Guide: File Access Applications.
■
Check host account .cshrc file.
Unless you specify an FTP password in your boot parameters, or include NFSclient
support in your VxWorks image, the default VxWorks access to host-system
files is based on capturing file contents through the rcmd( ) interface to the UNIX
host. For user accounts whose default shell is the C shell, this makes it imperative
to avoid issuing any output from .cshrc. If any of the commands in .cshrc generates
output, that output can interfere with downloading host files accurately through
rcmd( ). This problem most often shows up while downloading the VxWorks boot
image.
