"telnetrecon is currently under development. Please check the news section or subscribe to the rss feed to get the latest news from the project." - Marc Ruef, telnetrecon Project Maintainer


The first public release of telnetrecon has been posted to the project web site. This release includes the pre-compiled binary and the Visual Basic 6 source code of the version 0.1. This is not a major release yet because many features are missing. Especially the fingerprint database is very small and contain two example fingerprints only. Help to improve the project and upload new fingerprints of known telnet daemons.

The public release of telnetrecon 1.0 can be expected for the next two weeks. The current work is concentrating on the last optimizations of the data gathering and enumeration functions. Furthermore, as many telnet fingerprints as possible are collected. You are able to help to improve the fingerprint database before the official release. Just send me IP addresses and port numbers of public telnet servers in the Internet so I can collect the service fingerprints myself. Of course, the final release of the software will contain an upload feature for fingerprints as like httprecon have had it before.

The scip AG, a swiss consulting company I am affiliated with, is publishing the scip monthly security summary on a monthly base. In this month issue the telnet recon project was announced.

The telnetrecon project has been announced for the first time. It was named within my blog post with the title "Wenn man unliebsame Freunde zu Besuch hat" (Visited by unwelcome guests). The public release of the first version is planned for the upcoming weeks. An official announcement will follow.

The implementation of the first release of telnetrecon has begun. Therefore, the public project website has been launched to inform visitors about progress and the upcoming download. Check the news section or subscribe to the RSS feed to stay informed about the occuring progress.
