This file is generated by eMule to inform external applications about it's status. aMule is able to generate this file too in order to have compatibility with eMule utilities, but the native aMule signature file is amulesig.dat (which is much more powerfull than eMule's onlinesig.dat).
- whether it is online or not
- which server it's connected to
- upload and download rate
- clients in queue
It is composed of two lines separated by a line feed character (with no carriage return character):
- The first one, when aMule is offline, will contain a 0 (zero) and nothing else, but when aMule is online, it'll contain a 1 (number one) followed by | (the pipe character) then the name of there server it's currently connected to followed by the pipe character (|), then the IP of the server it's currently connected to followed by the pipe character (|) and finally the port it is connected to on that server.
- The second line contains, in this order, the downloading and uploading speeds (exactly one decimal is shown, neither mor nor less) and the number of users on queue, with a pipe character (|) between each of this fields.
The second line does not end in a newline character ('\n').
The following is the contents of a valid onlinesig.dat file when aMule is online:
1|eD2k Server|184.108.40.206|4661 (here goes a UNIX newline character 0xA)
The following is the contents of a valid onlinesig.dat file when aMule is offline (or closed but last status while open was online):
0 (here goes a UNIX newline character 0xA)
