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

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

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

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

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

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

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

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?
