Posted: Mon Jan 08, 2024 3:59 am Post subject: [SOLVED] ssh from linux to windows 11 using id_rsa.pub key

I installed openssh on windows 11, copied id_rsa.pub key to user directory .ssh\authorized_key
but when I try to ssh to it, it asking me for password.
It doesn't recognize public key.

Code:

Glen Server@10.0.0.130's password:

I don't know why I get error message: debug1: Authenticating to 10.0.0.130:22 as 'Glen Server'
debug1: load_hostkeys: fopen /home/joseph/.ssh/known_hosts2: No such file or directory

I have in .ssh/known_host file and it works perfectly fine with local and remote linux compuers. Even though I get a similar message.

Code:

debug1: Authenticating to 10.0.0.100:22 as 'joseph'
debug1: load_hostkeys: fopen /home/joseph/.ssh/known_hosts2: No such file or directory

The server is not accepting the ssh rsa key sent by the client. You said you copied it to .ssh\authorized_key. Is this a typo? The canonical name is authorized_keys, plural. This could have been changed on the server.

It was my typo, on Windows in user .ssh\ folder the file is called "authorized_keys"
I even copy the id_rsa.pub to windows and rename it to authorized_keys and move it to .ssh folder; it did not help.
It still asking me for a password, instead of using the key.

There are windows documentation pages available: https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_overview I suspect some format problems. also authorized_keys is a file, not a directory. The public contents (.pub) of your private ssh key needs to be copied (each line one key) into this file. _________________ Forum Guidelines PFL - Portage file list - find which package a file or command belongs to.

The part of the output that stands out to me is:

Code:

i don't claim to be an expert in the SSH protocol, but given the line:

Code:

debug1: Offering public key: /home/joseph/.ssh/id_rsa RSA

shouldn't there perhaps be a line along the lines of:

Code:

Trying private key: /home/joseph/.ssh/id_rsa

?

Also, as an aside, because of the Terrapin attack on SSH, you should configure the server to disable the chacha20-poly1305 cipher:

Code:

Ciphers -chacha20-poly1305@openssh.com

Somehow, the RSA key is not getting through to Windows ssh session; but connection ssh + password works.
So I'm puzzled why RSA key doesn't!

Windows is being offered "public key" but it trying "private key" why?

Both parts are needed. The way that the system works is that the private key of the person trying to log in needs to mathematically 'match' their public key as per the relevant entry in the authorized_keys file on the server.

i might well be wrong, but to hazard a guess, it might be that the server doesn't accept rsa keys (i.e. in its value of 'PubkeyAcceptedAlgorithms', e.g. 'ssh-rsa'); you can check this by examining the output of:

Code:

ssh -Q PubkeyAcceptedAlgorithms <Windows box IP>

More generally, you should check the logs of the ssh daemon on the Windows machine, to check what it might or might not be accepting.

Yes, I installed Windows 11 server, here is sshd_config:

Code:

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

#SyslogFacility AUTH
#LogLevel INFO

# Authentication:

#LoginGraceTime 2m
#PermitRootLogin prohibit-password
#StrictModes yes
#MaxAuthTries 6

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile .ssh/authorized_keys

#AuthorizedPrincipalsFile none

#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files

And yes, Windows user is in Admin group as well:

If I understand the official documentation (https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_keymanagement#administrative-user) correctly, the pubkeys of administrators have to be placed in %PROGRAMDATA%\ssh\administrators_authorized_keys and not under the user profile.

If I understand the official documentation (https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_keymanagement#administrative-user) correctly, the pubkeys of administrators have to be placed in %PROGRAMDATA%\ssh\administrators_authorized_keys and not under the user profile.
