63ffab643c61f932faabed8c6aa2b68eWatches for TCP connection, records state for the past 1 second - if multiple connections occur from the same host, an internal counter is increased for that IP. If the counter reaches some value (which can be changed in #define) scandetd will send email to administrator. Information sent includes time, ip address, number of connections made, first and last connection times, and guessed type of scan (syn/fin). Logs to syslog by default. Configurable to allow trusted addresses. Tested under linux - possibly sunos and freebsd.
49e46dec1be32115ddc605960a380dbfModified rexec source - captures ident information upon being portscanned. Does not actually emulate services other than listening at certain tcp ports. This is reported to work under Solarix 2.x and possibly linux. Now modified to provide limited counterintelligence (ident query back to source).
dd6eab901fadb0f386c97e3be850a33cThis logs and notifies you of portscans run against your host. Some kinds of D.o.S attacks might also get logged.

36bfa58cb8b54cd7152064e824128a82Fake Service version 1.1 - Fakes a Wingate service and Sendmail service, and listens for and logs scans on those ports.
fb889c3cc4211ed41dad168fa353f429Here's a modification of rexec that I call klaxon. Instead of actually executing anything, it returns a benign error to the caller, and syslogs the calling host, username, and name of attempted service access. It's also extremely useful for detecting portscanner attacks like those perpetrated by ISS and SATAN. Ident support (RFC931) is currently optional. klaxon is useful in place of any tcp or udp service port where you would not suspect activity. For Solaris2.X machines it will also work on the rpc.rexd port.
cb318c58e2411f887c6e169a60d87daePortwatch - acts a server, just sits on a port and waits for connections.
53c07cd3f96deb78c5021419467dc330RWX Back Orifice Sweep Scanner - RWXBO is a simple program that will log attempts to scan your ip range, and logs some commands that the attacker might type.
88d5fe7bb1063a45a2ca784185d39328Scandetd is a port scan detection daemon that waits for incoming tcp connections and tries to recognize port scans. If tripped, scandetd sends email to root@127.0.0.1 with the time, attacking host, number of connections made, port of the first and last connections. Easy on system resources; for Linux; initial release. 6k.

363cef4ee97ec41ad8cac88f27843f7fLatest release of J-Dog's portscan detector, now with the following features: uses nmap, queso, and nmbnamex to resolve remote "attacking/scanning" IP to a hostname, perform a tcp connect() scan on the remote host, grab the NetBIOS name of the scanner, and then use Queso to determine the OS of the remote host.
