To help debugging issues. Also: - bump sshd LogLevel to DEBUG1, for essential details. - bump command output buffer in `run_command_varg()` - drop redundant condition in `run_command_varg()` - replace `BUFSIZ` with literal sizes in `run_command_varg()`. After this patch it's showing this in the CI log for the libgcrypt fallout that previously needed a long time to diagnose: ``` 61: ---- sshd log ---- 61: No matching private key for certificate: /etc/ssh/ssh_host_mldsa44-ed25519_key-cert.pub 61: Server listening on 0.0.0.0 port 22. 61: Server listening on :: port 22. 61: debug1: sshd-session version OpenSSH_10.5, OpenSSL 3.6.3 9 Jun 2026 61: Connection from 172.17.0.1 port 51878 on 172.17.0.2 port 22 rdomain "" 61: debug1: sshd-auth version OpenSSH_10.5, OpenSSL 3.6.3 9 Jun 2026 [preauth] 61: debug1: list_hostkey_types: rsa-sha2-512,rsa-sha2-256,ssh-rsa,rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com,ssh-rsa-cert-v01@openssh.com,ecdsa-sha2-nistp256, ecdsa-sha2-nistp256-cert-v01@openssh.com,ssh-ed25519,ssh-ed25519-cert-v01@openssh.com [preauth] 61: debug1: Local version string SSH-2.0-OpenSSH_10.5p1 Debian-1 [preauth] 61: debug1: Remote protocol version 2.0, remote software version libssh2_1.11.2_DEV [preauth] 61: debug1: compat_banner: no match: libssh2_1.11.2_DEV [preauth] 61: debug1: SSH2_MSG_KEXINIT sent [preauth] 61: debug1: SSH2_MSG_KEXINIT received [preauth] 61: debug1: kex: algorithm: (no match) [preauth] 61: Unable to negotiate with 172.17.0.1 port 51878: no matching key exchange method found.
