BebboSSH AROS 1.0.9 is available for i386, x86_64 and aarch64. This maintenance release of my SSH/SFTP port fixes a subtle but important case: the server now responds correctly when the client initiates a channel close.
The project derives from BebboSSH by Stefan “Bebbo” Franke; the AROS port is my derivative work. This update does not introduce a full interactive shell.
When the client closes a channel
Previously, an SSH_MSG_CHANNEL_CLOSE sent first by the client could be ignored, with “unknown packet received 97” in the log. The client waited for a reply and the channel remained open until the connection ended.
The daemon now acknowledges the request, sends its own close and frees the channel. Idle sessions, SFTP and direct-tcpip are answered immediately; when a command is still running, the reply comes after it ends. No more messages are sent on the closed channel, and a close for an unknown channel is ignored.
An SFTP buffer fix
An SFTP session that had produced a large reply could leave its reply buffer allocated on close. The new version frees it. This is resource cleanup, not a protocol change or a new cipher.
Tests and remaining limits
The release notes document testing the archives on AROS One i386 and x86_64 under QEMU and on AROS aarch64 under QEMU. Cases include closing sessions, SFTP and forwarding, as well as OpenSSH SSH/SCP/SFTP checks. A Raspberry Pi 400 was not available for this release.
Important limits remain: no full interactive PTY, pipes or redirection in remote commands. On x86_64, commands are synchronous and may block the daemon; consult the platform notes for other execution and timeout details. A command timeout does not guarantee that the process is terminated. The x86_64 notes also flag a separate e1000 network driver problem under load and recommend rtl8139 or pcnet until the distribution includes the upstream fix.
