Tnm(n)Tnm Tcl Extension Tnm(n)_________________________________________________________________NAMETnm - Tcl extensions for network management applications.
_________________________________________________________________DESCRIPTION
The Tnm Tcl extensions has been written to simplify the
development of network management applications. The pri-
mary goal of the Tnm extension is to provide a string-
based API to access network protocols and services rele-
vant for network management applications. Some of the Tcl
commands provided by the Tnm extension are useful for more
general networked applications as well.
A string-based API simplifies the development of site spe-
cific management solutions because higher-level interfaces
encapsulate the complexity of some of the protocols sup-
ported by the Tnm extension. The use of the Tcl language
allows to integrate this extension with the Tk toolkit.
Management applications can thus be prototyped in a cost-
effective and platform independent way.
COMMAND OVERVIEW
Below is a short overview over the Tcl commands provided
the Tnm extension. There are separate man pages for each
command listed below which describes the command and its
options in more detail.
dns Query the Domain Name System of the Internet.
http Send and process HTTP requests.
icmp Send ICMP messages to hosts on the Internet.
ined Access and manipulate tkined objects.
job Invoke Tcl procedures at regular intervals.
mib Load and query SNMP MIB definitions.
netdb Access the local network databases.
ntp Retrieve control variables from NTP peers.
snmp Send SNMP messages to devices on the Internet.
sunrpc Call and probe selected Sun RPC services.
syslog Write messages to the system logger.
udp Send and receive UDP datagrams.

Tnm(n)Tnm Tcl Extension Tnm(n)ENVIRONMENT VARIABLES
TNM_LIBRARY Path to the Tnm library directory.
TNM_NTPING Path and name of ntping executable.
TNM_STRAPS Path and name of straps executable.
TNM_RCFILE Path and name of the initialization
file.
TCL VARIABLES
The Tnm extension defines the following global Tcl vari-
ables:
tnm(library) The path to the scotty library direc-
tory. This variable is initialized to
the compiled in default. You can over-
write this default by setting the
TNM_LIBRARY environment variable.
tnm(version) The version number of the Tnm extension.
tnm(arch) A string that identifies the architec-
ture and operating system. Note, this
will only work with Tcl version 7.5 and
higher.
tnm(host) The name of the local host executing the
Tcl process.
tnm(user) The name of the user running the Tcl
process.
tnm(mibs) This variable contains a list of SNMP
MIB files that are loaded automatically
if not preceded by a mib load command.
tnm(mibs:core) This variable contains a list of core
SNMP MIB files that are loaded even if
the first mib command is a load command.
FILES
~/.scottyrc Personal initialization file. May be
overwritten by the TNM_RCFILE environ-
ment variable.
$tnm(library)/site/init.tcl
Site initialization file. Use this file
to customize Tnm to your site specific
needs.
