Hello. I am running OpenSSH 7.9p1 on my client and server. ssh-keyscan shows the server has ssh-rsa, ssh-ed25519, and ecdsa-sha2-nistp256 host keys. My /etc/ssh/ssh_known_hosts file contains the server's ssh-ed25519 host key. When I try to SSH to the server I get this error: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

Hi guys, I'm working on a project which concern SSH and there is something i don't understand about server authentication. So I explain my problem: - When you authorize only RSA keys in the sshd_config on the server, you need to have the RSA public key of this server in the known_hosts file of the client. This is absolutely normal. - When you authorize only DSA keys in the sshd_config

I'm trying to use HostbasedAuthentication. Running ssh -v -v -v user at host the following error occurs: debug3: authmethod_is_enabled hostbased debug1: next auth method to try is hostbased debug2: userauth_hostbased: chost <host> debug2: we did not send a packet, disable method What does this mean ? I enabled HostbasedAuthentication in /etc/ssh/ssh_config and as it looks, this setting

Hello, I am using OpenSSH on a FreeBSD box (OpenSSH_3.5p1 FreeBSD-20030201, SSH protocols 1.5/2.0, OpenSSL 0x0090701f) and I noticed that the manual page for ssh_config probably needs to be fixed. The manual page says that the default value for the parameter HostKeyAlgorithms is "ssh-rsa,ssh-dss" but that seems to be wrong, because ssh only uses RSA-Keys in my .ssh/known_hosts if I

Hi SSH-devs, This may be a bit off topic for this list, but.... Would it be ok to share a private key in an installer script so long as the corresponding public key is setup like this... command="cat ~/.ssh/id_rsa.pub" ssh-rsa AAAA... I'm looking for a secure way to get a user to share their public key through SSH which can be invoked from an installer on another host...for

Hello & thanks for reading. I'm having a problem configuring known_hosts from scripts so an accept key yes/no prompt doesn't appear. I'm using this command to detect if the server is known and add it to known_hosts: if ! ssh-keygen -F ${IP_ADDR} -f ~/.ssh/known_hosts > /dev/null 2>&1; t hen ssh-keyscan -p ${PORT} ${IP_ADDR} >> ~/.ssh/known_hosts; fi This works

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello, I read and find a way (well, there seems to be several equal implementations) to collect the ssh keys of machines. However they all give only the choice to choose between the key formats. But is there a way to collect both keys of a machine, the rsa _and_ the dss key (and maybe the rsa1 too)? I didn''t find a way to solve this as

Hi, I am trying to run openssh 3.1p1. But it is giving "Bad packet length" error when I run sshd with default config file. On further investigation I found that the error is coming only for the cipher algorithm "aes128-cbc". Also the error comes only when I don't specify any protocol file (/usr/local/etc/ssh_host_[rd]sa_key) or specify only "protocol 2" files. I

Hi! I'm having a difficult time getting X11 forwarding to work. Since I've read the docs completely about this, this must be an SSH bug which is likely because I'm using Gentoo as the SSH server. When trying to forward X11 connections, I get X11 connection rejected because of wrong authentication. kwrite: cannot connect to X server XXXXXXXXX:10.0 Using command ssh -Y -p 1111 -4

Hi there, has anybody managed to get the eToken Pro Anywhere work with SSH? I'm using the latest SafeNetAuthentication drivers available for Ubuntu 64bit (8.3) and everything is working just fine except for ssh. I can use the eToken for logging in, openvpn, rdestkop, etc. but it seems ssh does not recognize the device properly. The command "ssh -I /usr/lib/libeToken.so.8 user at

OpenSSH 3.0 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. This release contains many portability bug-fixes (listed in the ChangeLog) as well as several new features (listed below). We would like to thank the

Hello, If one passes the -p option for a non-standard port to ssh-keyscan when using the -f option to pull hosts from a file, it results in a known_hosts entry that is incorrect: micah at muck$ cat /tmp/try 199.254.238.47 micah.riseup.net,199.254.238.47 ssh-keyscan -t rsa -p 4422 -f /tmp/try > /tmp/known micah at muck$ cat /tmp/known [micah.riseup.net,199.254.238.47]:4422 ssh-rsa

No I'm referring to "sshd -ddd" (preferrable on a high port like -p 8080 so you don't break your current ability to connect to the machine). As clearly the server is rejecting it. And only the server side debug can tell us that. - Ben Nick Stanoszek wrote: > I am using an AWS ubuntu 14.04 server...is that what you are asking? > > On Tue, Jul 28, 2015 at 10:00 PM,

Hello all, I have made SecurID authentication for OpenSSH 3.6.1p2. This patch was totaly rewritten, so please test it before use. Kbd-int authentication is now integrated into challenge response auth. Privsep is now fully suported. PS: What do you think of selective access to the individual authentications, similar to AllowGroups/DenyGroups or maybe AllowUsers/DenyUsers ? Vaclav Tomec

Hi OpenSSH, I encountered that SSH will hang over after I input the password. Could you help show me how to resolve this problem? Thanks for your help.
