Hi,

I try SFTP connect by ObjectScript.
But occurred this error. Can't connect by SFTP key-pair authentication.

:ERROR #7510: SSH Error '-18': SSH Error [80101012]: Username/PublicKey combination invalid [80101012] at Session.cpp:458,0

Key pair was generate this way.
ssh-keygen -m pem -f ~/.ssh/id_rsa
"id_rsa" and "id_rsa.pub" is generated.
Passphrase is empty.

sftp command is connect successful.
ex.
sftp -i .ssh/id_rsa sftpuser@localhost

And other SFTP client is connect successful too.
ex. Fillezilla.

And password authentication is successful too.

ObjectScript code is this.

ClassMethod SFTPDir() As %Status
{
    set ssh = ##class(%Net.SSH.Session).%New()
    Do ssh.SetTraceMask(511,"/tmp/ssh.log")
    Set sc = ssh.Connect("localhost")
    Write:$$$ISERR(sc) "Connect:", $System.Status.GetErrorText(sc),!
    Set sc = ssh.AuthenticateWithKeyPair("sftpuser","/path/to/id_rsa.pub","/path/to/id_rsa","")
    Set sc = ssh.AuthenticateWithUsername("sftpuser","/path/to/id_rsa.pub","/path/to/p_id_rsa","") 
    //Set sc = ssh.AuthenticateWithUsername("sftpuser","password") //success
    //Set sc = ssh.AuthenticateWithKeyPair("sftpuser","password") //success 
    Write:$$$ISERR(sc) "AuthenticateWithKeyPair:", $System.Status.GetErrorText(sc),!
    Set sc = ssh.OpenSFTP(.sftp)
    Write:$$$ISERR(sc) "OpenSFTP:", $System.Status.GetErrorText(sc),!

    Set sc = sftp.Dir(".",.files)
    Write:$$$ISERR(sc) "Dir:", $System.Status.GetErrorText(sc),!
    set i = $ORDER(files(""))
    while i '= "" {
        write $listget(files(i),1),!
        set i = $ORDER(files(i))
    }
    
    quit $$$OK
}

I think you got the methods reversed. To connect using the key pair you should use this method:

set sc = ssh.AuthenticateWithKeyPair( "sftpuser","/path/to/id_rsa.pub","/path/to/p_id_rsa","")

I have tested this and it works

Is the private key file "id_rsa" or "p_id_rsa"?

Are the key files in "/path/to/" directory?

What do you see in

/tmp/ssh.log

?

Hopefully you've figured this out by now but I'd suggest looking at the Filezilla logs to see if anythings stands out compared to the ssh log you get from IRIS.

My best guess is that the FTP server may not support specifically "key-pair" authentication or might require multiple forms of authentication and the other sftp methods you tried (Filezilla, sftp) may be succeeding with other auth methods. This is somewhat documented here:

https://docs.intersystems.com/iris20221/csp/documatic/%25CSP.Documatic.cls?LIBRARY=%25SYS&CLASSNAME=%25Net.SSH.Session#AuthenticateWithKeyPair

You could reach out to the WRC with this.

Thanks for the reply.
Sorry for the misunderstanding.
The sample program has been modified.

The same error occurs in the modified sample program.

Thank you very much.

I will check the normal logs against the abnormal logs.

Was there a resolution for this issue? I'm encountering the exact same error on RedHat Linux 9. I've verified that the public and private keys are in the correct formats and that the permissions are properly set for the files and directories. But AuthenticateWithKeyPair() generates the same error.

The same key pair work properly to initiate a ssh/scp/sftp session in the Linux shell. They're in the .ssh directory under the irisusr account, which is the account under which HealthConnect runs, $ZV IRIS for UNIX (Red Hat Enterprise Linux 9 for x86-64) 2023.1.2 (Build 450U) Mon Oct 16 2023 11:29:24 EDT.

So ... after trying a LOT of different options, I finally uncovered the issue. The version of %Net.SSH.Session() in the HealthConnect release I'm working with (2023.1.2) requires ssh-rsa to be enabled on the remote server. And ssh-rsa requires the deprecated SHA1 algorithm which is disabled on RHEL 9.

The workaround is to issue the following command as root:

[root ~]# update-crypto-policies --set DEFAULT:SHA1

I'm hoping there's an update that eliminates the need to do this; the WRC has been notified.

score 0 · Answer 7 · 2024-07-23T13:16:28-04:00

The WRC recommended I try signing the key with ed25519, and that works without having to re-enable SHA1.

$ ssh-keygen -t ed25519

copy the id_ed25519.pub file from the .ssh directory to authorized_keys in the remote host's .ssh directory and make sure the permissions are set to 400 for ~/.ssh and the files within.
