new code on the server

I tcpdumped a bit less than an hour (and a bit less than 2 gigs :-)
full duplex tcpdump file for testing on intel and ppc (for endian issues).
It looks like two file processing (i.e. argus -r eth2 -r eth3) doesn't match
the output from a single tcpdump file merged with tcpmerge (which is why less
than 2 gigs input files :-)). I'll see if I can get time to create a releasable
test file for that one.
As well there looks to be a difference in port lists between the two
architectures (due to forgetting to put the -n on the ra command):
both.ppc.ra.out
07-05-14 08:09:00 e udp 206.12.16.133.43003 -> 129.240.67.15.43003 1 0 912 0 INT
07-05-14 08:09:00 e s tcp 206.12.16.134.ndl-aa -> 198.32.154.186.46133 4 3 272 222 FIN
07-05-14 08:09:00 e icmp 217.153.194.26 -> 206.12.16.134 5 0 350 0 URH
both.intel.ra.out (FreeBSD leaves ndl-aa as port 3128 for some reason):
07-05-14 08:09:00 e udp 206.12.16.133.43003 -> 129.240.67.15.43003 1 0 912 0 INT
07-05-14 08:09:00 e s tcp 206.12.16.134.3128 -> 198.32.154.186.46133 4 3 272 222 FIN
although it still breaks with the -n added (just much later :-)):
both.ppc.ra.out:
07-05-14 08:13:36 e tcp 205.167.120.201.14084 -> 142.58.211.125.80 9 8 1112 4999 FIN
both.intel.ra.out: (flags has an s that the other doesn't)
07-05-14 08:13:36 e s tcp 205.167.120.201.14084 -> 142.58.211.125.80 9 8 1112 4999 FIN
in theory these two should be identical (although at this point its
unclear if this is an argus or client issue). It looks like we are clear of
endian issues at this time, but I guess I'll have to manually edit the s in
to the ppc output and continue the compare to be sure :-). It may be an
argus issue because I'd expect the two argus files to be identical and they
are not:
