Why does this happen? Who's fault is it? As these are TCP connections I would expect it is not a problem to know what packet belongs to what connec...

all but one lan host (gv)can ssh connect to host 2x Included windows 10, several linux. 2x is a solaris host. That problem host (gv) can connect to all others but 2x. 2x can connect to all other encluding the problem host (gv) So gv ssh to 2x throws this error: ssh_dispatch_run_fatal: Connection to 192.168.1.42 port 22: incorrect signature. 192.168.1.42 is 2x. So incoming ssh from gv to 2x has the problem. So far I have removed all ssh config and files on both hosts and reinstalled openssh. The problem remains Below is the full output of ssh -vv gv (a gentoo host) ssh t...

This is a problem with ssh, not with rsync. Try enabling ssh debug options, and try using different ssh ciphers....

I have a cron script that polls various machines for their configs and archives any changes. When it connects to an OpenWrt router running "OpenSSH_9.1p1, OpenSSL 1.1.1s 1 Nov 2022", it sometimes gets this error: Bad packet length 1231976033. ssh_dispatch_run_fatal: Connection to 192.168.8.1 port 22: message authentication code incorrect What's odd is that the length is *always* 1231976033 (which is 0x496E7661 or "Inva" in ASCII). The client is Ubuntu 22.04.2 LTS, and it's version is "OpenSSH_9.1p1, OpenSSL 3.0.2 15 Mar 2022"....

...chment 3614 --> https://bugzilla.mindrot.org/attachment.cgi?id=3614&action=edit patch with a kludge fix An update to net-misc/openssh-9.0_p1-r6 (Gentoo port) this morning led immediately to nondeterministic (~50% failure rate) connection failures, both in ssh and sshd, with this message: ssh_dispatch_run_fatal: Connection to a.b.c.d port 22: incorrect signature It quickly became apparent that the problem only affected connections authenticated with ED25519. I found, by instrumenting ed25519.c:crypto_sign_ed25519_open(), that bit #256 (of 255 valid bits) in sm[] was nondeterministically set or clear,...

In sshconnect.c there are two global variables for server_version_string client_version_string. These are used just in a few functions and can easily be passed as parameters. Also, there is a strange construct, where their memory is allocated to the global pointers, then copies of these pointers are assigned to the kex structure. The kex_free finally frees them via cleanup of the kex
