NAME
hostname_map - tell ToolTalk clients to use a per-host
alternative rpc.ttdbserverd(1M)
SYNOPSIS
hostname_map
DESCRIPTION
A ToolTalk hostname_map tells ToolTalk clients to use host
A's rpc.ttdbserverd(1M) as a proxy for host B. In this way,
ToolTalk databases can be created for filesystems exported
from hosts (like host B) that for whatever reason do not run
rpc.ttdbserverd(1M).
The hostname_map file is called "hostname_map" and resides
in the same directories as the ToolTalk types databases; see
tt_type_comp(1). If $TT_HOSTNAME_MAP is set, it is used in
place of $HOME/.tt/hostname_map.
ToolTalk clients read the hostname maps when the ToolTalk
client library is initialized in e.g. tt_open(3). ttses-
sion reads the hostname maps upon startup and rereads them
if it receives signal USR2.
Format rules
The format rules for a hostname_map are:
1. Any line beginning with a "#" or white-space and a "#" is
a comment.
2. Blank lines are comments.
3. Words are delimited by white space.
4. The first word in a non-comment line is the host name
from which to map.
5. The second word in a non-comment line is the host name to
which to map.
ENVIRONMENT
TT_HOSTNAME_MAP
If $TT_HOSTNAME_MAP is set, it is used in place of
$HOME/.tt/hostname_map.
TTPATH
A colon-separated list of directories in which to seek
hostname_maps. See tt_type_comp(1).
EXAMPLES
This example maps "mainframe1" to "sparcstorage":
# rpc.ttdbserverd cannot run on filesystems
# exported from mainframe
mainframe1 sparcstorage
