Hello, In response to the timing analysis attacks presented by Dawn Song et. al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html we at Silicon Defense developed a patch for openssh to avoid such measures. Timing Analysis Evasion changes were developed by C. Jason Coit and Roel Jonkman of Silicon Defense. These changes cause SSH to send packets unless request not to,

Hi all, Over the past 10 years, there has been some discussion and several patches concerning keystroke timing being revealed by the timing of openssh packet network transmission. The issue is that keystroke timing is correlated with the plaintext, and openssh users expect their communications to be kept entirely secret. Despite some excellent ideas and patches, such as Jason Coit's

I'm reading this fine article on O'Reilly: http://linux.oreillynet.com/lpt/a//linux/2001/11/08/ssh_keystroke.html <quote> The paper concludes that the keystroke timing data observable from today's SSH implementations reveals a dangerously significant amount of information about user terminal sessions--enough to locate typed passwords in the session data stream and reduce the

Hi folks. FYI: There's a discussion[0] about keystroke timing attacks against SSH going on on the cryptography mailing list. Would be interesting to hear the opinion of some OpenSSH folks what SSH/OpenSSH is doing against this and what could maybe be don in addition. Especially since the main idea behind the attack is obviously not limited to the initial authentication phase when a password

I want to use R to run a reaction-time experiment: Something appears on the screen, I respond by typing something (one keystroke), the system measures the speed of my response. R would be great for this if only I didn't have to hit Enter to enter that keystroke. I am doing such experiments now but they require two actions per trial: hit keystroke, hit Enter. Is there some way that R can be

Hello, My name is Pavan and I was working on the timing attacks in Open SSH. I wanted to know where I can find the patch files for open SSH as I am not able to find it on the specified link. Thank You

Greetings! The original version of this tutorial was written by Curt Hibbs and published on ONLamp.com. It served as my introduction to both Ruby and Rails. Unfortunately, I experienced some frustration working through it. This was due first to the fact that I was using Instant Rails, not Rails, and second, to the fact that Rails itself has grown since Curt wrote the article. Despite my

Ventrilo in version 2.1.4 work properly good under wine. I talk with friend without any problems with sound, but there is one with "Push-to-talk" function (hotkey). When frame with ventrilo have lost focus i can't use this function. I spent a lot of time to googled about it and I found program called xbindkeys. I got idea, that I can use this program to send keystroke to ventrilo.

Here is my system Fedora 10 Avant Stellar Keyboard (uses Northgate Omnikey 101 layout) wine 1.1.14, 1.1.15, and 1.1.16 Problem: While in game, doesn't matter which, I've tried this with World of Warcraft, and Counter-strike. I have a problem with keystrokes registering 2 keystrokes behind. Example: While typing in game if I type the word "Anyone" the 'A' and

I also ported it to use libedit instead, but readline is more

I post this to the mailing list, but perhaps is not the good place. I'm not subscribed, so I don't know if I'm going to get any reply, but please, tell me where to send patches. I attach two patches that correctly describes the new support for F11 and F12 in documentation but I have two more question to update documentation accordingly. In doc/syslinux.txt line 515, talking about

Hello Syslinux Team, What actions are _supposed_ to be triggered by each of: [Ctrl-J] [Ctrl-M] in the Syslinux command line in version 6.03-pre20? Are there any differences between CLI and [vesa]menu.c32 regarding these keystroke combinations? Are there any differences in their behaviors when booting with different Syslinux variants (e.g ISOLINUX vs. SYSLINUX vs. PXELINUX)? To be

Last week my trusty Fedora 9 file and print server failed on me. Not bad for 12 years trusty service. I have now replaced it with a C7 server and found that lots have changed in those 12 years. Thankfully many things haven't, named-chroot, dhcpd, etc pretty much copied across and Samba wasn't a major rewrite. However I feel like my right arm has been chopped off.? My work life

Hello, What do you recommend for keeping track of user activities? For preserving bash histories I followed these recommendations: http://www.defcon1.org/secure-command.html They include using 'chflags sappnd .bash_history', enabling process accounting, and the like. My goal is to "watch the watchers," i.e. watch for abuse of power by SOC people with the ability to view
