The ON SOCKOPEN event triggers when a TCP socket connection initiated with /sockopen is either successfull or failed. This event also trigger after an SSL negociation (STARTTLS feature) is finished, you can check $sock().starttls which will be set to $true if the negociation was successful.
Synopsis[edit]
ON <level>:SOCKOPEN:<matchtext>:<commands>
Parameters[edit]
<level>The corresponding access levels for the event to trigger.
<matchtext>The name of the socket you want the event to trigger on.
<commands>The commands to be performed when the event listener's criteria is met.
Connection State[edit]
Because the sockopen event triggers for failed connections as well as successful connections, it's important to check the value of $sockerr before continuing with any commands. Here is a list of the possible values returned by $sockerr in the on SOCKOPEN event:
- 0 - Success.
- 3 - Failure establishing socket connection: $sock($sockname).wsmsg will contain a more specific error message.
- 4 - Error resolving given hostname.
Examples[edit]
on *:sockopen:example:{ ;if an error occurred ($sockerr is not 0) if ($sockerr) { if ($sockerr == 3) { echo -s An error occurred while trying to connect: $sock($sockname).wsmsg } elseif ($sockerr == 4) { echo -s Error resolving hostname } } ;no error occurred ($sockerr was 0) else { ;perform commands after establishing a connection. ;usually this involves making a request for a webpage as shown below: sockwrite -n $sockname GET / HTTP/1.1 sockwrite -n $sockname Host: www.example.com sockwrite -n $sockname Connection: close sockwrite $sockname $crlf } }
