In http://docs.freebsd.org/cgi/mid.cgi?200402260743.IAA18903 it seems RELENG_4 is vulnerable. Is there any work around to a system that has to have ports open ?

Dear list, A few days ago one of my machines were attacked by a DDoS-attack using UDP on random ports.. When I later on analyzed the logs, I found this in my dmesg: xl0: initialization of the rx ring failed (55) xl0: initialization of the rx ring failed (55) xl0: initialization of the rx ring failed (55) I tried to find out on google what it ment, but without any luck. What does that mean and

hi is there any way to build 4.8 release with this fstack protection? or atleast some ports is there any good info on this? the only page i found was that ibm page but it seemed outdated. //martin

Hi, folks @ freebsd-security. First, I am not sure if this is apropriate topic for that list, so sorry, if it is not. Some time ago I have read rfc1948 (protection from blind TCP spoofing) and became interested in the way how it is implemented in FreeBSD. After some googling (BTW if you like Google you might be interested in this: http://register.spectator.ru/img/bart.gif ), I found this:

Hello, all! In the beginning I want to say, that this question seems to be a security one, isn't it so?.. Recently I was googling for the subject and coulnd't find anything... Even in the opennet.ru forum nobody answered me about this. So, as far as I got to know, randomizing source ports in FreeBSD is impossible now? (to be exact - is not implemented?) It's very interesting to me

Here's my proposed patch to change RST handling so that ESTABLISHED connections are subject to strict RST checking, but connections in other states are only subject to the "within the window" check. Part 2 of the patch is simply a patch to netstat so that it displays the statistic. As expected, it's very straightforward, the only real question is what to call the statistic...

Hi there, I'm still running 6.2 on various servers without any tweaks (GENERIC kernel, binary updates via freebsd-update etc.) but lots of ports (apache, postgresql, diablo-jdk etc.) and would like to use stack smashing protection in order to harden my boxes and avoid many potential exploits. I've known about ProPolice/SSP for a while now (from the Gentoo world) and am aware that

Attached is a security alert from Gentoo pertaining to clam antivirus. It seems that as of this morning, FreeBSD's ports still contain the affected version.

As promised, the updated if_xl with full busdma support / other improvements has been MFC'd to 4.8-stable. While I have put this driver through extensive testing, it is possible that there may be bugs which are either present in the -current version or that I added in the MFC process. So, if you cvsup to -stable anytime in the future and notice problems with if_xl, please tell me ASAP!

As others have noted, Tor's patch appears to be a total solution to the recent instability the PAE patch introduced. So, if you're experiencing panics with a recent kernel, or are in a position to stress a machine, please cvsup and give it a test!

Hello, I current have a FreeBSD 4.8 bridge firewall that sits between 7 servers and the internet. The servers are being attacked with syn floods and go down multiple times a day. The 7 servers belong to a client, who runs redhat. I am trying to find a way to do some kind of syn flood protection inside the firewall. Any suggestions would be greatly appreciated. -- Ryan James ryan@mac2.net

This is a common thread and I'm wondering where they answer is.. I can see this theme posted many times -- recently here https://lists.samba.org/archive/samba/2015-May/191483.html and for which I was not able to find a solution The situation is this.. Samba 4.2 compiled from source on ubuntu 14. server. Samba 4.2 AD DC is working great in sliced server. the samba member server joined fine.

Any chance of this being implemented in fbsd? Could be usefull ;-) ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt -- :{ andyf@speednet.com.au Andy Farkas System Administrator Speednet Communications http://www.speednet.com.au/

If anyone was using a bfe card and seeing interrupt storms when you attempted to bring the card up, this is the fix for you. The driver wasn't previously taking into account the fact that the chipset doesn't like addresses over the 1GB mark. If you'd like an even quicker fix, just add hw.mem = "1000M" to your loader.conf and reboot. :) Mike "Silby" Silbersack

Hello out there, everybody! I was actually expecting to find several (hundred) threads with this subject being discussed. To my surprise I didn't find a single one either on these mailing lists or in the newsgroups - at least not in a language I understand. :-) I realize that gbde and geli are not designed to be better than the other but that both fit different needs and different tastes.

Hello, For some reason, I thought little about the "clear" command today.. Let's say a privileged user (root) logs on, edit a sensitive file (e.g, a file containing a password, running vipw, etc) .. then runs clear and logout. Then anyone can press the scroll-lock command, scroll back up and read the sensitive information.. Isn't "clear" ment to clear the
