GETIF home page

What is getif ?

A small utility, that can halp you to ask SNMP devices as routers, switches, servers, and make usual job on IP hosts (lookup, ping, traceroute). It runs on windows 95/98/NT machines. In some images, here is getif. (beware, the image correpond maybe not to the latest version ...)

History

1997 : getif 1.3 (not available anymore) (unzip, run the install.bat programm)

june 1998 : getif 2.0 (not available anymore)(unzip, run setup.exe)

end-june 1998 : getif 2.1 (not available anymore)(unzip, run setup.exe)

•     'general tab' introduce : you can define (in registry) every SNMP table that you need, and look at it with getif ... (see below)
•     one or two bug less ... (false DNS name makes a GPF, ...)

october 1998 : getif 2.2 (available here)(unzip, run setup.exe) (beta, can change ...)

• added a SNMP traceroute function
• added a graph functionality

Graph TAB

This TAB allows to make 2 kinds of graphs : the ping roud-trip delay, or the value of a SNMP (integer/gauge/counter).

To add an element on this graph, you have 3 possibilities :

• press the 'graph' button in the 'reachability' tab, this graphs the round time delay of the host
• select the 'graph' round trip delay' in the menu that appears when the left mouse button is pressed on a grid that contains ip addresses
• press the 'graph' button in the mib browser tab, after a good value has been selected in the browse list.

You can select the refresh time (ex. 0.8 ), the number of points to display,  if you want a legend, axes labels or 3d rendering (try ctrl-click). If you right-click out of the graph, you can copy it on clipboard, and paste it (values or graph ('paste special')) in an other application.

The 'delete' button erase the select entry in the combo box, the 'init' erase all entries, and the 'clear' erase only the values (not the entries).

Parameters TAB

Used to enter hostname, define default SNMP parameters, the path of the telnet application, and to save or restore the application default settings.

Interfaces TAB

Addresses TAB

Routing table TAB

ARP table TAB

Reachability TAB

You can make a standard ping, and test the ability of the remote host to serve on specified TCP ports ...

General table TAB

You can define, in registry, a set SNMP tables like this one  :

[HKEY_CURRENT_USER\Software\getif\GenTable\CustomTables\5]
"Name"="frCircuitTable (.1.3.6.1.2.1.10.32.2)"
"0"=".1.3.6.1.2.1.10.32.2.1.1|Int.|3|6|0|3"
"1"=".1.3.6.1.2.1.10.32.2.1.2|Dlci|3|6|0|3"
"2"=".1.3.6.1.2.1.10.32.2.1.3|State|6|0|0|3"
"3"=".1.3.6.1.2.1.10.32.2.1.4|Rx FECN|7|6|0|3"
"4"=".1.3.6.1.2.1.10.32.2.1.5|Rx BECN|7|6|0|3"
"5"=".1.3.6.1.2.1.10.32.2.1.6|Tx frms|8|6|0|3"
"6"=".1.3.6.1.2.1.10.32.2.1.7|Tx bytes|9|6|0|3"
"7"=".1.3.6.1.2.1.10.32.2.1.8|Rx frms|8|6|0|3"
"8"=".1.3.6.1.2.1.10.32.2.1.9|Rx bytes|9|6|0|3"
"9"=".1.3.6.1.2.1.10.32.2.1.10|Creation time|9|6|0|3"
"10"=".1.3.6.1.2.1.10.32.2.1.11|Last change|9|6|0|3"
"11"=".1.3.6.1.2.1.10.32.2.1.12|C.burst|5|6|0|3"
"12"=".1.3.6.1.2.1.10.32.2.1.13|Ex burst|7|6|0|3"
"13"=".1.3.6.1.2.1.10.32.2.1.14|Thrput|4|6|0|3"

Rules :

• These tables are numbered from 0 to ..., and placed after 'GenTable\CustomTables'.
• They have a 'Name', that is displayed in the dialog box
• they have columns, numbered from 0 to n, with the following syntax (all items separated with '|'):
  • .1.3.6.1.2.1.6.13.1.1 the oid where to look for this value
  • 'Title' : the column's title
  • 'nn' : the width of the column, in 'characters'),
  • 'n' : alignement (0 = right, 6 = left)
  • 'n' : is an IP name or address (0 : no, 1 : yes), influence the right-click
  • 'n' : sort type (5 : numeric; 3 : strig no case)

You can have a sample reg file here.

Here is this sample :

Traceroute TAB

This one can make an ICMP or a SNMP traceroute.
The ICMP traceroute is a normal traceroute with ICMP packets with different TTL.
The SNMP traceroute reads part of the routing tables from the host define in the 'parameter' tab to the destination defined on this tab. All hops must be SNMP-able, and reachable with the community name defined in the 'parameter' tab. I hope that the algorithm used to follow a route is not false (!)

Resolver

This is a graphical interface of the bind 4.9.5 nslookup (ftp://ftp.vix.com/pub/bind/release). Getif can use its own resolver or go through the resolver of MS. It has a name cache too, that can be disabled.

Subnet discovery

A big name only to indicate the you can ping a list of devices to see the occupation of a subnet ...

SNMP Mib browser

A graphical interface of the UCD SNMP tools. (ftp://ftp.ece.ucdavis.edu:/pub/snmp/ucd-snmp.tar.gz)

Hints

With the left mouse button, in all tables or tabs, you can make a lot of things (e.g. copy, telnet ...)

Look at the getif.log file in the getif directory, when problems occures. As i use the UCD-SNMP and the BIND resolver, their standard output and error output are redirected in this file during execution. This can help typically when you add mibs files from differents vendors.
