Description

The nettool package consists of a Pure-tcl set of tools to perform common network functions that would normally require different packages or calls to exec, in a standard Tcl interface. At present nettool has reference implementations for the following operating systems: Windows, MacOSX, and Linux (debian).

Commands

::cat filename
Dump the contents of a file as a result.
::nettool::allocate_port startingport
Attempt to allocate startingport, or, if busy, advance the port number sequentially until a free port is found, and claim that port. This command uses a built-in database of known ports to avoid returning a port which is in common use. (For example: http (80))
::nettool::arp_table
Dump the contents of this computer's Address Resolution Protocol (ARP) table. The result will be a Tcl formatted list: macid ipaddrlist ...
::nettool::broadcast_list
Returns a list of broadcast addresses (suitable for UDP multicast) that this computer is associated with.
::nettool::claim_port port ?protocol?
Mark port as busy, optionally as either tcp (default) or udp.
::nettool::cpuinfo args

If no arguments are given, return a key/value list describing the CPU of the present machine. Included in the matrix is info on the number of cores/processors that are available for parallel tasking, installed physical RAM, and processor family.

The exact contents are platform specific.

For Linux, information is drawn from /proc/cpuinfo and /proc/meminfo.

For MacOSX, information is drawn from sysctl

For Windows, information is draw from TWAPI.

If arguments are given, the result with be a key/value list limited to the fields requested.

Canonical fields for all platforms:

cpus
Count of CPUs/cores/execution units
speed
Clock speed of processor(s) in Mhz
memory
Installed RAM (in MB)
vendor
Manufacturer
::nettool::find_port startingport
Return startingport if it is available, or the next free port after startingport. Note: Unlike ::nettool::allocate_port, this command does not claim the port.

This command uses a built-in database of known ports to avoid returning a port which is in common use. (For example: http (80))
::nettool::hwid_list
Return a list of hardware specific identifiers from this computer. The source and content will vary by platform.

For MacOSX, the motherboard serial number and macids for all network devices is returned.

For Windows, the volume serial number of C and macids for all network devices is returned.

For Linux, macids for all network devices is returned.
::nettool::ip_list
Return a list of IP addresses associated with this computer.
::nettool::mac_list
Return a list of MACIDs for the network cards attached to this machine. The MACID of the primary network card is returned first.
::nettool::network_list
Return a list of networks associated with this computer. Networks are formated with ip::nativeToPrefix.
::nettool::port_busy port
Return true if port is claimed, false otherwise.
::nettool::release_port port ?protocol?
Mark port as not busy, optionally as either tcp (default) or udp.
::nettool::status

Return a key/value list describing the status of the computer. The output is designed to be comparable to the output of top for all platforms.

Common fields include:

load
Processes per processing unit
memory_total
Total physical RAM (MB)
memory_free
Total physical RAM unused (MB)
