anondate-get[edit]

Diagnostic utility. anondate-get. A "higher level" easier to use tool than the "lower level" anondate.

Usage of anondate-get should be safe. It does not use networking. It does not change time. Only looks at locally available information.

sudo anondate-get

Sample output.

/usr/sbin/anondate-get: INFO: 100% Tor bootstrap, ok.
/usr/sbin/anondate-get: INFO: tor_circuit_established_check.py, ok.
/usr/sbin/anondate-get: INFO: Tor circuit already established, ok.
/usr/sbin/anondate-get: INFO: current time in valid in range, ok.
/usr/sbin/anondate-get: INFO: Tor certificate lifetime valid, ok.
/usr/sbin/anondate-get: END: Exiting with exit_code '3' indicating 'Could not determine any time using Tor from consensus or certificate life time.'.

anondate-set[edit]

Security impact has yet to be documented.

anondate-set.

sudo anondate-set

anondate[edit]

Introduction[edit]
Consensus Related Options[edit]
  • --verified-only
  • --prefer-verified
  • --unverified-only
Special Exit Codes[edit]
  • exit 3: $TOR_LOG not readable.
  • exit 4: $consensus not readable.
Simple Status Checking[edit]
anondate --has-consensus[edit]

Useful for checking if asking for any #Date Ranges Output is worthwhile.

  • yes:
    • exit 0
  • no:
    • exit 1


Can be replaced by Tor ControlPort / python-stem?

  • verified-only: Yes. (consensus/valid-after)
  • unverified: No.
anondate --current-time-in-valid-range[edit]

Useful for a sanity test before setting the time for the first time and before setting the time to a newly fetched timestamp.

  • yes:
    • exit 0
  • no:
    • exit 1


Can be replaced by Tor ControlPort / python-stem?

Date Ranges Output[edit]
anondate --show-valid-after[edit]
  • yes:
    • output: 2015-08-15 22:00:00
    • exit 0
  • no:
    • exit 1


Can be replaced by Tor ControlPort / python-stem?

anondate --show-valid-until[edit]
  • yes:
    • output: 2015-08-16 01:00:00
    • exit 0
  • no:
    • exit 1


Can be replaced by Tor ControlPort / python-stem?

anondate --show-middle-range[edit]
  • yes:
    • output: 2015-08-15 23:30:00
    • exit 0
  • no:
    • exit 1


(A scripted calculation of the above.)

Certificate Validity[edit]

When clock is several months or years fast or slow, Tor cannot even download Tor consensus. Tor however always should be providing a certificate lifetime. For security discussion, see also Tor Certificate Lifetime.

anondate --tor-cert-lifetime-valid[edit]
Sep 03 10:32:59.000 [warn] Certificate already expired. Either their clock is set wrong, or your clock is wrong.
Sep 03 10:32:59.000 [warn] (certificate lifetime runs from Aug 16 00:00:00 2014 GMT through Jul 29 23:59:59 2015 GMT. Your time is Sep 03 10:32:59 2015 UTC.)
  • yes:
    • output: Sep 03 10:34:00.000 [warn] Certificate already expired. Either their clock is set wrong, or your clock is wrong.
    • exit 0
  • no:
    • exit 1

Can be replaced by Tor ControlPort / python-stem? No. Tor Project Upstream Feature Request: make certificate lifetime accessible through Tor's ControlPortarchive.org

anondate --tor-cert-valid-after[edit]

Similar to above, but less output.

  • output: Jun 16 00:00:00 2014 GMT
  • Exit codes unreliable.
  • Don't use without using the above first.
  • (Could be fixed in the code if worthwhile.)
