NAME

ipsweep

SYNOPSIS

DESCRIPTION

Discovers network devices on the subnets managed with NerveCenter.

OPTIONS

-d

Specifies debug mode and outputs debug messages to the console.

-f excludefile

Specifies a file that contains a list of IP addresses for ipsweep to ignore.

-t timedelay

ICMP timeout interval. timedelay is a value in milliseconds (default is 20 milliseconds).

-m mapfile

Specifies a map file that contains node information about the network.

IP Filters must still be configured in the NerveCenter Administrator's IP Filters page for each subnet that is discovered. The map file uses the subnet and mask value to match an existing pair in the IP Filters page. The Map file does not specify which subnets to discover. It just specifies the read community string used for a subnet if it is discovered.

-ttl hops

Specifies the time to live (TTL) value for IPSweep, where the valid value is between 0 and 255 hops. The default value for -ttl is: 255 hops (128 for Windows © 2002).

-h

Provides command line help for ipsweep.

USAGE

On startup, ipsweep can read a map file specified by the -m switch. This map file contains a table as follows:

The first line should be the ‘Default DefaultReadCommunity’ line. A single blank separates the word Default and the community string. Each of the lines following the Default line will be in the format specified above. These lines will be a Subnet immediately followed by a slash (“/”) immediately followed by the Mask. The “Subnet/Mask” is followed by a single blank and then the community string.
