ssh-multisession-resume is intended for Linux hosts running OpenSSH server configuration compatible with sshd_config Match Address blocks.

The package manages:

• a package-owned command under /usr/bin
• package-owned helper files under /usr/lib/ssh-multisession-resume
• an operator-approved managed block in /etc/ssh/sshd_config
• per-user shell profile hooks
• an optional per-user systemd unit

Package upgrades replace only package-owned files. Host-owned configuration is preserved unless the operator runs ssh-multisession-resume or ssh-multisession-resume rollback.

The tool does not bypass SSH authentication or grant shell access. OpenSSH still authenticates users normally. The managed Match Address block only sets SSH_AUTO_RESUME=1 for already-authenticated interactive logins from configured IPv4 addresses or IPv4 CIDR ranges.

Interactive auto-attach is skipped for:

• noninteractive SSH commands
• sessions without a TTY
• shells already inside tmux or screen
• logins that do not match the managed OpenSSH criteria

IPv6 matching is not implemented.

If a report includes sensitive host details, redact usernames, public IPs, private hostnames, and SSH configuration that is unrelated to the issue.
