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

...The broader issue of hiding all potential keystroke timing is not yet fixed. The keystroke timing issue would be solved by adding LINEMODE support as I did back in 2010. https://lists.mindrot.org/pipermail/openssh-unix-dev/2010-June/028732.html The code is still available here https://github.com/hyc/OpenSSH-LINEMODE/ If there's sufficient interest this time, I can probably bring it all up to date with a current OpenSSH version. I won't bother if it meets the same apathy as last time. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun htt...

My Linux kernel patches for linemode support have been pulled into the 2.6.36 release stream, so I figure it's time to finish up the work on openssh, bash, tcsh, readline, libedit, and anything else that comes along. As I last wrote here http://wiki.github.com/hyc/OpenSSH-LINEMODE/ I've got a few open issues remaining... First, I re-organized muxed session handling such that all terminal input is handled by each ssh process, instead of being handled by the single connection manager process. This was the cleanest way to divide the labor since the var...

Hey all, So I do some development based on openssh and I'm trying to think of some new projects that might extend the functionality, feature set, user workflow, performance, etc of ssh. So open ended question: Do any of you have a wish list of things you'd like to see in ssh? Mostly I'm just curious to see what the larger community is thinking of rather than being driven

Hi fellow devs, I was looking for a way to run C on the JVM and i found LLJVM which apparently does exactly that! Howevere,unfortunately it seems dead on the main david's git https://github.com/davidar/lljvm as well as the slightly newer one https://github.com/hyc/lljvm. They don't seem to compile, once i run make in the root directory it give me the error : " *In file included from main.cpp:23:0:* *backend.h:29:44: fatal error: llvm/Analysis/ConstantsScanner.h: No such file or directory* * #include <llvm/Analysis/ConstantsScanner.h>* *...

Hello list, RFC 4253 provides for per-packet random padding, the length of which depends on the payload and the cipher block size. If I understand correctly, for OpenSSH (5.7) this is done in packet.c lines 674-684 and 881-911? Although the padding itself is random, its length is not, and the final packet size is just a step function of the size of the payload. This can be a problem to some
