Hi folks: I know this is trivial stuff, but I want to remove banners used by all listening daemons. This is good for security, because at least it's annoying for hackers who mostly based their attacks in version numbers appearing in daemon banners. For instance, on SuSE 6.4, running SMTP: 220 machine_name.domain ESMTP Sendmail 8.9.3/8.9.3/SuSE Linux 8.9.3-0.1; Thu, 26 Oct Is it possible to change banner without having to re-compile the Sendmail sources??? I've had a look to /etc/sendmail.cf. There is an entry which contains "DZ8.9.3/SuSE Linux 8.9.3-0.1". So I suppose there will be no problems if I change it to any string I want. But... could I remove the "Sendmail" string or simply remove the banner completely and change to "220 machine_name.domain Microsoft Mail Server"??? I think I'd have to recompile Sendmail... (not the db's, I'm referrering to the sendmail source code)- The question extends to any other daemons like Proftpd, Qpopper, etc.. Is it easy to achieve it? Thx a lot. PS: Banners are very important to hackers (or at least script-kiddies) wanting to penetrate your machine. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ** RoMaN SoFt / LLFB ** roman@madrid.com http://pagina.de/romansoft ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
