  v0.5.5 — SFTP-over-SSH remote shares Pre-Release

  OpenPXE v0.5.5 — SFTP-over-SSH remote shares

  Adds SFTP as a third remote ISO-library protocol alongside SMB and NFS.

  docker pull gitea.milesward.dev/mward4/openpxe:0.5.5   # or :latest
  

  What's new

  • SFTP remote shares — point OpenPXE at an SSH/SFTP server and boot ISOs straight off it. Pure-Rust (russh + russh-sftp, ring crypto backend): no kernel mount, no subprocess, no OpenSSL, no new C dependencies.
  • HTTP Range support — like NFS (and unlike SMB), SFTP-sourced ISOs support byte-range reads (the SFTP file handle seeks), so kernel/initrd extraction and httpdisk range requests work.
  • Auth — password or SSH private key (optional passphrase). The server's SSH host key is pinned trust-on-first-use; a changed key is refused with a clear warning.
  • UI — "SFTP (SSH)" added to the Remote shares protocol dropdown with a password/key toggle and host-key fingerprint display. Plus sftp terminal commands (list/add/remove/scan) and /api/sftp-shares.

  Why not SCP

  SCP is sequential-only (no random access → no HTTP Range, unlike SFTP/NFS), and the mature Rust SCP crates wrap libssh2 (C + OpenSSL), which would break the static-musl, OpenSSL-free build.

  Notes

  • russh is pinned to =0.55.0 — the newest release that coexists with the SAML crypto stack (bergshamra-crypto pins RustCrypto release-candidate crates that conflict with russh 0.61's stable ones). Functionally identical; ring-backed, OpenSSL-free.
  • Static x86_64-unknown-linux-musl binary; 252 tests pass, clippy clean.
