possible ettercap license issue. - legal - Fedora mailing-lists

8 Feb 2011


      This is in the code of ettercap... (ec_main.c)
268 static void time_check(void)
269 {
270    /* 
271     * a nice easter egg... 
272     * just to waste some time of code reviewers... ;) 
273     *
274     * and no, you can't simply remove this code, you'll break the license...
275     *
276     * trust me, it's not evil ;) only a boring afternoon, and nothing to do...

The comment strikes me as a GPL incompatibility. (License is GPLv2+)
Should anything be done about this ?
(The obfuscated code seems to check a date, and print a message asking you
to send birthday wishes to the author. Cute, but annoying to come across such
things when auditting for security issues).
