The Time Service

• To be able to sync the time from a machine we don't have an account on, we have the time service(s).
• Standard ports 'daytime' (13) and 'time' (37) are used to export these services, by xinetd.
• 'daytime' uses a text protocol:

  [choo@simey ~]$ telnet 127.0.0.1 daytime
  Trying 127.0.0.1...
  Connected to 127.0.0.1.
  Escape character is '^]'.
  22 AUG 2005 00:56:39 IDT
  Connection closed by foreign host.
  [choo@simey ~]$
  

• 'time' uses a binary protocol:

  choo@simey ~]$ telnet 127.0.0.1 time
  Trying 127.0.0.1...
  Connected to 127.0.0.1.
  Escape character is '^]'.
  Ƴw7Connection closed by foreign host.
