Firewalk works by sending out TCP or UDP packets with a TTL one greater then the targeted gateway. If the gateway allows the traffic, it will forward the packets to the next hop where they will expire and elicit an ICMP_TIME_EXCEEDED message. If the gateway host does not allow the traffic, it will likely drop the packets on the floor and we will see no response. ftpcheck Perl script to scan class-c networks for machines running FTP ftpscan FTP-bounce portscanner halfscan Half opened connection portscanner hping070-lin hping v0.70 for Linux, tool for testing packet filters hping070-sol hping v0.70 for Solaris, tool for testing packet filters ident-scan TCP portscanner that uses identd querying Identscan Can be useful to determine who is running daemons on high ports that can be security risks. imapd_scan Shellscript to exploit entire networks using the Linux IMAP vulnerability IP Tools 2000 Many Network/Internet Information Tools!

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. Netcop 2.0 Windows Port Scanner. newscan Half opened connection portscanner nmap nmap is a utility for port scanning large networks, although it works fine for single hosts. The guiding philosophy for the creation of nmap was TMTOWTDI (There's More Than One Way To Do It). This is the Perl slogan, but it is equally applicable to scanners. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). You just can't do all this with one scanning mode. And you don't want to have 10 different scanners around, all with different interfaces and capabilities. nmap for NT nmap ported to Windows NT. phobia Utility to scan networks for various Unix holes probe Simple TCP portscanner scanner Windows based port scanner with source. strobe Strobe is a network/security tool that locates and describes all listening tcp ports on a (remote) host or on many hosts in a bandwidth utilisation maximising, and pro-cess resource minimizing manner.
