Re: BSD display
Hi Steve, Nothing can stop a hacker who really wants your box, but most of the annoyances are script kiddies. Script kiddies when things get tough tend to move on to another system. So whatever I can to not help script kiddies is to my advantage. This might be true, yes. They might not care and try every trick in their toolkit. One of my 'problems' with this approach lies with the move on to another system. So now they're hitting on *my* systems... ;-) Someone, somewhere has to deal with these creatures and get them caught/slapped in the face/buttkicked. I report whenever I can, which is all I can do, I guess. Plus (back to the original topic), if we both upgrade regularly, whose box is more secure? Yours or mine? :-) Bye...

Notice that this won't help OpenBSD people, as they are the only ones who do not have the p (for portable) in their OpenSSH version number. You'd still know they are running OpenBSD. :-) GH ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: BSD display
Harald, Well I don't want to get into any courtsy controversies or licensing gimmicks. But what the steve said has a good point. Lets think it that way that just a casual onlooker cant make out what OS and version is running on the box. It makes the life of a cracker just a little more difficult. However more promising guyz and galz can find it out anyway. Regards S. On Wed, 8 Sep 2004 05:52:30 +0200, Harald Schmalzbauer [EMAIL PROTECTED] wrote: Am Mittwoch, 8.

Re: BSD display
Hi Steve, Displaying the OS helps a hacker know which approach cracking into a box. This may be true. OTOH, not displaying the version of [insert software package of the day here] may invite a 'hacker' to pull a full-scale all-out number on you, trying every possible exploit he can get his hands on. Or simply DDoS you out of this universe. Or launch whatever OS-agnostic attack can be performed. I'm sure there have been long discussions over this 'security by obscurity' thing *somewhere*... ;-) Buhbye... Nico P.S. I guess nothing beats common sense coupled with regular upgrading. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
