NAME
hostname_map - tell ToolTalk clients to use a per-host alternative
rpc.ttdbserverd(8)
SYNOPSIS
hostname_map
DESCRIPTION
A ToolTalk hostname_map tells ToolTalk clients to use host A's
rpc.ttdbserverd(8) as a proxy for host B. In this way, ToolTalk data-
bases can be created for filesystems exported from hosts (like host B)
that for whatever reason do not run rpc.ttdbserverd(8).
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). ttsession reads the host-
name 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 host-
name_maps. See tt_type_comp(1).
EXAMPLES
This example maps "mainframe1" to "sparcstorage":
# rpc.ttdbserverd cannot run on filesystems
# exported from mainframe
mainframe1 sparcstorage
