what is the “Online Certificate Status Protocol”

2011-03-09 Thread erikmccaskey64
I use privoxy. In the user.action file i have a redirect rule and a few 
websites: 


{ +redirect{s@http://@https://@} }
.twitter.com
.facebook.com


Ok! it's working great, e.g.: if i visit any "*twitter.com" URL it gets 
redirected to HTTPS!


But: with wireshark i can see some "OCSP" packets [ 
http://en.wikipedia.org/wiki/Online_Certificate_Status_Protocol ]


Question: What are these packets? Why aren't there in HTTPS?


Is my redirection method with privoxy is secure?


Thank you for any tips/opinions!

Is it safe to run tcpdump?

2011-03-05 Thread erikmccaskey64
Is it safe to always run tcpdump on the server, e.g.: like this:


tcpdump -qn dst net 192.168.1.0/24


I need it to "audit the network" .. :\

Re: script help

2011-02-15 Thread erikmccaskey64
my little opinion: first run the changes on a backup, or a copy of the files:

this one works under linux bash fedora:
how to create a "shadow" of a folder [same filenames in another dir, but with 0 
Byte size]


in the original, "A" directory:
find . -type f > a.txt


"B" directory:
cat ../a.txt | while read file; do if [[ "$file" = */* ]]; then mkdir -p 
"${file%/*}"; fi; touch "$file"; done




so if something goes wrong, there would be no trouble

Security: gnome-screensaver VS. switch user

2011-02-13 Thread erikmccaskey64

People "usually" suspend their laptop, so that they can continue their work 
when they open the laptop. OK!


Two choices [GNOME]:  


1 - Menu -> Shut Down -> Suspend
in this case, the gnome-screensaver locks the PC. but the gnome-screensaver is 
just a "normal process", and it could be killed e.g.: 
http://securitytube.net/USB-Autorun-attacks-against-Linux-at-Shmoocon-2011-video.aspx
or using any method [video was just an example!!].






2 - Menu -> Log out -> Switch user -> Suspend
in this case, the GDM [???] protects the user [i mean it locks the PC from 
other users]




Which one is more secure/safer?
