Name

systemd-ssh-issue — Generator for SSH login prompt drop-ins

Synopsis

/usr/lib/systemd/systemd-ssh-issue --make-vsock
/usr/lib/systemd/systemd-ssh-issue --rm-vsock

Description

systemd-ssh-issue is a small tool that generates a /run/issue.d/50-ssh-vsock.issue drop-in file in case AF_VSOCK support is available in the kernel and the VM environment. The file contains brief information about how to contact the local system via SSH-over-AF_VSOCK, in particular it reports the system's AF_VSOCK CID. The file is typically read and displayed by agetty(8) on console or serial login prompts.

This tool is automatically used by systemd-ssh-generator(8) in the AF_VSOCK socket units it generates.

Options

The following options are understood:

--make-vsock

Generates the issue file. This command has no effect if called on systems lacking AF_VSOCK support.

Added in version 258.

--rm-vsock

Removes the issue file if it exists.

Added in version 258.

--issue-path=

Changes the path to the issue file to write to/remove. If not specified, defaults to /run/issue.d/50-ssh-vsock.issue. If specified as empty string or "-" writes the issue file contents to standard output.

Added in version 258.

-h, --help

Print a short help text and exit.

--version

Print a short version string and exit.

Exit status

On success, 0 is returned, a non-zero failure code otherwise.
