I had originally mentioned this only to 2 people, which was Jordan K. Hubbard and Paul Henning-Kemp, but since I have received a lot of queries on this, I thought I might as well post it on the FreeBSD announce groups. Included below is a posting done on the Linux-atm mailing group, by Pragnesh Sampat. I have just adapted for FreeBSD. RV -------------------------- Announcement

On a FreeBSD 5.0 the behaviour of screen when connecting to other users sessions have changed. Previously: 1. login as userA start a screen as userA and disconnect 2. login as root su - userA "screen -r" 3. result failure as userA cant access the ttyX with such a message Current: 1. login as userA start a screen as userA and disconnect 2. login as root su - userA "screen -r" 3.

We have a number of Soekris devices that we will be deploying remotely in semi- hostile physical environments. The remote links are dialup so I dont have a lot of bandwidth available. I want to do integrity checks of the images so that I can detect any tampering of the flash image. If I upload a static sha256 binary to /tmp on the remote box (which is a RAM disk) and then do something

Howdy! I'm not sure if this is actually an issue, feature or a bug, but I have found that inside a jail, the jailed root user is able to sniff traffic (and enable promiscuous mode) on at least the interface of the IP address the jail is attached to. I have not found any documentation explaining if this should occur or not, but I feel it is something that should at least be known to those

Hi, I'm pondering building my own SSL accelerator out of a multi-CPU FreeBSD system and a crypto accelerator. What's the recommended hardware crypto accelerator card these days?

I've included all posts till now. Can I ask anyone with older proliant multi-cpu hardware using the smart2 controllers to get in touch with me? I am curious to know if this works for anyone... -D Quoting Danny Carroll <fbsd@dannysplace.net>: > Still more info... > It does not work on 5_0-RELEASE either. > > -D > ----- Original Message ----- > From: "Danny

Although RAW sockets can be used when specifying the source address of packets (defeating one of the aspects of the jail) some people may find it usefull to use utilities like ping(8) or traceroute(8) from inside jails. Enclosed is a patch I have written which gives you the option of allowing prison-root to create raw sockets inside the prison, so

I have a grown list of IPs that I am "deny ip from ###.### to any". Infected machines, hackers, etc.. Is there a way to have this list outside of rc.firewall and just read it in?

Hello, I think there was already a thread on this. I just want to raise the question again if anyone has successfully booted an gdbe-encrypted filesystem (everything encrypted except the bootloader). The passphrase is entered at the bootloader prompt or embedded in the bootloader. I appreciate any tips. Thanks, - ronnel

Hi. I've been playing a bit with "use sound card as an entropy source" idea. This simple program does what I wanted: http://people.freebsd.org/~pjd/misc/sndrand.tbz The program is very simple, it should be run with two arguments: % sndtest /dev/dspW 1048576 > rand.data This command will generate 1MB of random data. With my sound card: pcm0: <Intel ICH3 (82801CA)>

I seem to be able to lock my machine by going into wpa_cli and asking it to 'reassoc'. The reason for question mark after "hard" is that debug information (caused by wlandebug and athdebug) is being printed on the console. The only way to get machine's attention is to hold power button for 8 seconds. Note: manual reassociation is just the handy way to reproduce the problem

Is it possible to find a repository that hold a newer version of tar. The current version is 1.26 I have some students trying to build Yocto project on my Centos 7 host, but OpenEmbedded reports incompatibility problems with the current version of tar. I thank you on beforehand for any help. |< -- Med venlig hilsen Klaus Kolle Teknikumingeni?r, B.Sc.EE., e-mail : klaus at kolle.dk

Hi all! I found this today on FD: http://seclists.org/fulldisclosure/2012/Aug/4

Is anyone successfully using some sort of hardware crypto solution to combat the overhead of SSL in http transactions?

Hi, A collegue of mine wants to go wireless at his home. Anyone got any buyer tips for a low-maintenance 54Mb brand/model and Centos? Kind regards Barrie

I read this (http://www.petur.eu/blog/?p=459) blog post today. It's about that a remote user with root privilegs to a FreeBSD jail & user privileges to the jails host machine can obtain root privileges on the host machine. Can someone confirm if this bugg/exploit works?

Hi all. This might seem really naive, but can mtree be used effectively as a native-to-core-OS tripwire equivalent? Would it be as efficient in terms of time-to-run and resource requirements? What sort of pitfalls should I be aware of? Has anyone here done this? If so, would you care to share your scripts/techniques? Thanks, Dave -- ______________________
