Subject: [Buildroot] sshd reports error in libcrypto while trying to read host key
Date: Wed, 31 Mar 2021 14:12:15 +0000	[thread overview]
Message-ID: <DM6PR08MB4425422C1100F44BFF129275AE7C9@DM6PR08MB4425.namprd08.prod.outlook.com> (raw)

Hello,

I?ve built openssh and I?m having some issues running it on my board. While running sshd it reports an error in libcrypto while trying to read the host key. The host keys are generated under /etc/ssh.

~> ls /etc/ssh
moduli                                 ssh_host_ecdsa_key                    ssh_host_rsa_key
ssh_config                           ssh_host_ecdsa_key.pub           ssh_host_rsa_key.pub
ssh_host_dsa_key             ssh_host_ed25519_key              sshd_config
ssh_host_dsa_key.pub     ssh_host_ed25519_key.pub

~> systemctl status sshd
? sshd.service - OpenSSH server daemon
     Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled; vendor preset: enabled)

Mar 31 13:21:02 cm1sd systemd[1]: sshd.service: Failed with result 'exit-code'.

I?m using:
openssh version 8.5p1
openssl version 1.1.1k
crpytodev-linux fabe5989a3d

Is there an issue using this combination of packages? These are the lastest versions in buildroot.

My config file (sshd_config) is only trying to load the host key for RSA, but I get the same error about libcrypto for ecdsa and ed25519.

Anyone see this issue as well? Any help is appreciated.

Thanks.
-Michael
