I'm not so sure that it's Sub7, the "SERVER" string in the log
looks like a host and port number - rather than a host and process
ID. Especially when Google turned up the following for "port 4302":
wrcmdc /wrcmds=the_server /rport=4302 /user=myuser /pwd=mypassword
=> the client will connect to the_server on port 4302, authenticate
itself as myuser (with password mypassword) and ask the server to
You will only need the username and password if you configure the
server to use authentication.
The communication between the client and the server is done via 1 TCP
port, the default is 4302 (this can be change via the configurator
for the server and via the commandline/GUI for the client). The
communication is encrypted, it's the server that selects the
encryption schema and encryption password. Both are valid for ONE
session only. The server can be configured to accept connections from
all IPs or from just some IPs. Server can also be configure to use
I suspect someone might have found a buffer overflow for WRCMDS.
