Description

SSH-AGENT-FILTER

NAME

ssh-agent-filter - filtering proxy for ssh-agent meant to be forwarded to untrusted servers

SYNOPSIS

ssh-agent-filter [ OPTIONS ]

DESCRIPTION

ssh-agent-filter provides the unix domain socket interface of an ssh-agent. By default it forks and outputs shell code setting SSH_AUTH_SOCK and SSH_AGENT_PID, just like ssh-agent does.

It filters each request according to its command line options. No crypto operations are done by ssh-agent-filter; they are delegated to the upstream ssh-agent.

ssh-agent-filter is not meant to be used directly, but through afssh.
