Old news, but ... http://lwn.net/Articles/298833/ I first posted about this back in 2001 and it's still not resolved: http://osdir.com/ml/ietf.secsh/2001-09/msg00000.html 1) high latency networks are a reality that will never go away. In fact they will only become more prevalent since distributed networks continue to grow broader but (surprise) the speed of light remains a constant. 2)

I'm looking at the code from CVS as of May 21. The statement to allocate the mux state is allocating the size of a pointer, instead of the size of the struct being pointed to. The bug is benign in the original code because the struct has only an int element inside it, but it would corrupt memory if the struct were to be extended. Simple fix here: diff --git a/mux.c b/mux.c index

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

Hi, just read the LLVM 2.6 release announcement, the bit about llvm-mc caught my attention. I've been looking for a tool to disassemble x86 object files into an IR and then reassemble them into x86_64 object code. The immediate use for them would be to convert driver blobs that some vendors provide for their hardware (e.g. the Lucent modem driver) so they can be used in a 64 bit kernel.

Picking up on a couple really old threads (e.g. http://osdir.com/ml/ietf.secsh/2001-09/msg00003.html ) I've finally gotten around to this. The EXTPROC support on Linux is missing, but you can find kernel patches for that here http://lkml.org/lkml/2010/6/11/403 I've also fixed up the netkit telnet / telnetd code to work with EXTPROC / LINEMODE on Linux, those patches are here

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

Hello everybody, I'd like to have LPK (or something like that - getting public keys from LDAP) integrated into mainline OpenSSH. *** First of all, a summary. The project page at http://code.google.com/p/openssh-lpk/ mentions that a few distributions include LPK per default; but reading the various threads at Support for merging LPK and hpn-ssh into mainline openssh?

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

This may be more relevant to an IETF mailing list but I figured I'd start here first. I ran across this because signals need to be sent as explicit commands, not as special characters, when using EXTPROC. So I started implementing the "signal" channel request. However, the description of the request is inadequate. RFC4254 section 6.9 says the 'signal name' values are the

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