NAME

       nbtscan --  program for scanning networks for NetBIOS name information

SYNOPSIS

       nbtscan	[-v]   [-d]   [-e]   [-l]   [-t  timeout]   [-b  bandwidth]   [-r]   [-q]   [-s separator]  [-h]  [-m retransmits]  [-f filename |
       scan_range]

DESCRIPTION

       This manual page documents briefly the nbtscan command.

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

       nbtscan is a program for scanning IP networks for NetBIOS name information. It sends NetBIOS status query to each address in supplied range
       and  lists  received information in human readable form. For each responded host it lists IP address, NetBIOS computer name, logged-in user
       name and MAC address (such as Ethernet).

OPTIONS

       A summary of options is included below.

       -v	 Verbose output. Print all names received from each host.

       -d	 Dump packets. Print whole packet contents. Cannot be used with -v, -s or -h options.

       -e	 Format output in /etc/hosts format.

       -l	 Format output in lmhosts format. Cannot be used with -v, -s or -h options.

       -t timeout
		 Wait timeout seconds for response. Default 1.

       -b bandwidth
		 Output throttling. Slow down output so that it uses no more that bandwidth bps.  Useful on slow links, so  that  ougoing  queries
		 don't get dropped.

       -r	 Use local port 137 for scans. Win95 boxes respond to this only.  You need to be root to use this option.

       -q	 Suppress banners and error messages.

       -s separator
		 Script-friendly output. Don't print column and record headers, separate fields with separator.

       -h	 Print human-readble names for services.  Can only be used with -v option.

       -m retransmits
		 Number of retransmits. Default 0.

       -f filename
		 Take IP addresses to scan from file "filename"

       scan_range
		 What  to  scan.  Can  either  be  single  IP  like  192.168.1.1  or range of addresses in one of two forms: xxx.xxx.xxx.xxx/xx or
		 xxx.xxx.xxx.xxx-xxx.

BUGS

       Report bugs to alla@sovlink.ru (that's autor of nbtscan). I cannot promise to do anything but I might well want fix it. Remember:  no  war-
       ranty.  At least it's worth what you payed for it.

NAME

       grepcidr -- Filter IP addresses matching IPv4 CIDR/network specification

SYNOPSIS

       grepcidr [-V]  [-c]  [-v]  [-e pattern | -f file]

DESCRIPTION

       This manual page documents briefly the grepcidr command.

       This manual page was written for the Debian distribution because the original program does not have a manual page.

       grepcidr  can  be  used to filter a list of IP addresses against one or more Classless Inter-Domain Routing (CIDR) specifications, or arbi-
       trary networks specified by an address range. As with grep, there are options to invert matching and load patterns from a  file.   grepcidr
       is capable of comparing thousands or even millions of IPs to networks with little memory usage and in reasonable computation time.

OPTIONS

       -V	 Show software version

       -c	 Display count of the matching lines, instead of showing the lines

       -v	 Invert the sense of matching, to select non-matching IP addresses

       -e	 Specify pattern(s) on command-line

       -f	 Obtain CIDR and range pattern(s) from file

EXAMPLES

       grepcidr -f ournetworks blocklist > abuse.log

       Find our customers that show up in blocklists

       grepcidr 127.0.0.0/8 iplog

       Searches for any localnet IP addresses inside the iplog file

       grepcidr "192.168.0.1-192.168.10.13" iplog

       Searches for IPs matching indicated range in the iplog file

       script | grepcidr -vf whitelist > blacklist

       Create a blacklist, with whitelisted networks removed (inverse)

       grepcidr -f list1 list2

       Cross-reference two lists, outputs IPs common to both lists
