  48. using my client, i will ping myself.. in other words calculate the duration of a roundtrip.. me -> server -> me.
  49.  
  50. -> bartol.freenode.net PRIVMSG akkit :PING 1281281927
  51. <- :akkit!~TheHypnot@cpc4-nmal17-2-0-cust41.croy.cable.virginmedia.com NOTICE tikkadee :PING 1281281927
  52.  
  53. so, my client sends the message..
  54.  
  55. privmsg destination :[PING timestamp]\n
  56.  
  57. the client that receives that message will then reply with..
  58.  
  59. NOTICE source :[PING same_timestamp]\n
  60.  
  61. the irc server will translate that, to this..
  62.  
  63. :akkit!~TheHypnot@cpc4-nmal17-2-0-cust41.croy.cable.virginmedia.com NOTICE tikkadee :PING 1281281927
  64.  
  65. :nickname!~ident@hostname NOTICE source :[PING same_timestamp]\n
  66.  
  67. so..
  68.  
  69. there is a thing called a moon bounce..
  70.  
  71. you transmit a radio signal from earth, and it is then reflected off of the moon and received again back on earth..
  72.  
  73. similarly with a ping, you send a message and wait for it's reply. if you send anything, you simply see that original message reflected back at you and that is quite useless...
  74.  
  75. unless it's a time stamp
  76.  
  77. PING 1281282499
  78.  
  79. 3 seconds later i receive that message
  80.  
  81. i put into a variable my own time stamp at this precise moment .. 1281282502
  82. subtract the old timestamp from the new one.. 1281282499
  83.  
  84. 1281282502 - 1281282499 = 3
  85.  
  86. since the timestamp is in whole seconds, we now know it took at least 3 seconds and less than 4 in order to complete the round trip..
  87.  
  88. why did i say it's best the client sends this?
  89.  
  90. well, I was thinking about being able to reuse that so any client can ping another client on demand to discover their current ping time.. such as during high load / utorrenting or whatever..
  91.  
  92. that being said, of course, nothing stopping the server from iniating these pings.. of course, in fact.. they do anyway.
  93.  
  94. <- PING :bartol.freenode.net
  95. -> bartol.freenode.net PONG :bartol.freenode.net
  96.  
  97. the server just sent me it's name inside of a ping, since, ping responses contain the original message it's safe to assume they reply will be the server name - not that it really matters but it's nice to know that it probably will. (cant be arsed to read the RFC on IRC protocol right now to confirm)..
  98.  
  99. so yeah, my client responded with PONG.
  100.  
  101. notice that the protocol looks different from above..
  102.  
  103. to and from a server
  104. <- PING :bartol.freenode.net
  105. -> bartol.freenode.net PONG :bartol.freenode.net
  106.  
  107. to and from a client
  108.  
  109. -> bartol.freenode.net PRIVMSG akkit :PING 1281281927
  110. <- :akkit!~TheHypnot@cpc4-nmal17-2-0-cust41.croy.cable.virginmedia.com NOTICE tikkadee :PING 1281281927
  111.  
  112. etcetc
  113.  
  114.  
  115. helps at all?
  116.  
  117. here are some other things that can be sent over IRC protocol..
  118.  
  119.  
  120.  
  121. -> bartol.freenode.net PRIVMSG akkit :VERSION
  122. <- :akkit!~TheHypnot@cpc4-nmal17-2-0-cust41.croy.cable.virginmedia.com NOTICE tikkadee :VERSION mIRC v6.35 Khaled Mardam-Bey
  123. -> bartol.freenode.net PRIVMSG akkit :FINGER
  124. <- :akkit!~TheHypnot@cpc4-nmal17-2-0-cust41.croy.cable.virginmedia.com NOTICE tikkadee :FINGER ... (...) Idle 120 seconds
  125.  
  126. yup, you can finger unsuspecting people.. hehehe
