USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
rc5 6169 0.0 0.4 224 220 p0- IN 14Apr97 41728:30.94 rc5 -n 10 -a bovine.st.hmc.edu rsacrack@vex.net
The above RC5 key cracking client has been running for over a
month now, and I would like to see it break the 100000 CPU minutes
mark. :) The problem is that the bovine.st.hmc.edu keyserver it uses
has gone away, and it does not appear that the client re-resolves the
name when retrying the connection.
Is it possible to run something like natd or ipfilter on my
machine (on which the client is running) to rewrite the destination
address of outgoing packets? I would like to reroute packets destined
for 134.173.46.17 UDP port 2056 to 199.45.111.6 UDP port 2056. The
NAT software I've seen only seem to be able to rewrite the source
address on outgoing packets, and destination address on the return
packet. I want the exact opposite. Possible? The machine is running
a FreeBSD 3.0 snapshot from January, and I have IPFIREWALL, IPDIVERT
and a bpf device enabled in the kernel.
