After the file is created locally, you can use FTP to transfer it to your PC.

If you want it to go directly to your PC, then you'll need more software on the empeg (this gets complicated rather quickly).

Eg. NFS configured on the empeg, so it can mount a (Linux) PC filesystem for writing out the log file directly.

Or perhaps run telnetd on the empeg, so that you can telnet in from another PC (putty on MS-Win) and run the strace player from within the telnet session. No log file required with this method, instead just let strace spew its output directly over telnet to the remote PC. Save the session log afterwards to save the log messages.

But again, this may all be beyond your current level of expertise.
