v23agentd

Documentation

Overview

Command v23agentd manages the security agent daemon, which holds the private key, blessings and recognized roots of a principal in memory and makes the principal available to other processes.

Other processes can access the agent credentials when V23_AGENT_PATH is set to <credential dir>/agent/sock.

Without arguments, v23agentd starts the agent to exclusively serve the specified credentials.

Exits right away if another agent is already serving the credentials. Exits when there are no processes accessing the credentials (after a grace period).

Example:

$ v23agentd --credentials=$HOME/.credentials
$ V23_AGENT_PATH=$HOME/.credentials/agent/sock principal dump

Usage:

v23agentd [flags]
v23agentd [flags] <command>

The v23agentd commands are:

stop        Stops the agent
help        Display help for commands or topics

The v23agentd flags are:

-create=false
  Whether to create the credentials if missing.
-credentials=
  Credentials directory.  Defaults to the V23_CREDENTIALS environment variable.
-daemon=true
  Run the agent as a daemon (returns right away but leaves the agent running in
  the background)
-timeout=0
  How long the agent stays alive without any client connections. Zero implies
  no timeout.
-with-version=0
  Version that the agent should use.  Will fail if the version is not in the
  range of supported versions (obtained from the --metadata flag)

The global flags are:

-alsologtostderr=true
  log to standard error as well as files
-log_backtrace_at=:0
  when logging hits line file:N, emit a stack trace
-log_dir=
  if non-empty, write log files to this directory
-logtostderr=false
  log to standard error instead of files
-max_stack_buf_size=4292608
  max size in bytes of the buffer to use for logging stack traces
-metadata=<just specify -metadata to activate>
  Displays metadata for the program and exits.
-stderrthreshold=2
  logs at or above this threshold go to stderr
-time=false
  Dump timing information to stderr before exiting the program.
-v=0
  log level for V logs
-vmodule=
  comma-separated list of globpattern=N settings for filename-filtered logging
  (without the .go suffix).  E.g. foo/bar/baz.go is matched by patterns baz or
  *az or b* but not by bar/baz or baz.go or az or b.*
-vpath=
  comma-separated list of regexppattern=N settings for file pathname-filtered
  logging (without the .go suffix).  E.g. foo/bar/baz.go is matched by patterns
  foo/bar/baz or fo.*az or oo/ba or b.z but not by foo/bar/baz.go or fo*az
