514
Port 514 carries syslog, the standard for shipping log messages to a central server.

Where 514 fits
Why 514 is special
Centralised logging is what makes an incident reconstructable: logs held only on a compromised machine can be edited by whoever compromised it. Classic syslog on 514 uses UDP and offers no delivery guarantee or encryption, which is why regulated environments use its TLS successor instead.

DXIV uses the subtractive pair IV: one before five — five minus one.

2 × 256 + 0 × 16 + 2 × 1 = 514
Read as powers of two: 512 + 2 = 514.
In historical numeral systems
Egyptian
5 coils of rope, 1 hobble, 4 strokes
5 × 100 + 1 × 10 + 4 × 1 = 514. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
8 vertical wedges (sixties place), 3 corner wedges + 4 vertical wedges (units place)
8 × 60 + 34 = 514. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
phi, then iota, then delta, marked as a numeral
phi-iota-delta + keraia
phi + iota + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then qof, then yod, then dalet
tav-qof-yod-dalet
tav (400) + qof (100) + yod (10) + dalet (4) = 514, written in descending order.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
Syslog ships logs to a separate machine and Tor's control port manages a local process. Both exist because the thing being observed and the thing observing it should not be the same host.

Technology & computing
Sending logs to a separate machine is what makes an incident reconstructable, since logs on a compromised host can be edited by whoever compromised it. Classic syslog offers neither encryption nor delivery guarantees, which is why its TLS successor exists.

Common questions
Is 514 a prime number?
No, 514 is not prime.
What are the factors of 514?
The factors of 514 are 1, 2, 257, 514.
What is 514 in Roman numerals?
514 in Roman numerals is DXIV. IV is subtractive: one before five — five minus one. Written additively it would be DXIIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
