To send a file to a specific host, use the function
send_file(int host_id, const char* file_name);
or the command line program (run from the project root directory)
send_file -host_id X -file_name Y
send_file creates a result and initializes it with a name of the form send_FILENAME_HOSTID_TIME.
A message is created for the host and added to the msg_to_host table. This message instructs the client to download the file and acknowledge a successful download. The download message included in the next RPC reply to the host. The message has the form:
<app>
<name>FILE_MOVER</name>
</app>
<app_version>
<app_name>FILE_MOVER</app_name>
<version_num>n</version_num>
</app_version>
<result>
<wu_name>x</wu_name>
<name>y</name>
</result>
<file_info>
<name>file_name</name>
<url>download_dir/file_name</url>
<md5_cksum>md5</md5_cksum>
<nbytes>file->nbytes</nbytes>
<sticky/>
</file_info>
<workunit>
<name>result.name</name>
<app_name>FILE_MOVER</app_name>
<file_ref>
<file_name>file_name</file_name>
</file_ref>
</workunit>
For this to work, you need to include <msg_to_host/>
in config.xml.
