hostname_map(4) ToolTalk Commands hostname_map(4)NAMEhostname_map - tell ToolTalk clients to use a per-host alternative
rpc.ttdbserverd(1M)SYNOPSIShostname_mapDESCRIPTION
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 data‐
bases 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). 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
