racluster rc.42 problems

[Michael Sanderson]

I have argus 2.0.6-fixes.1 + ... running on OpenBSD 4.0-stable and have a 
collector running on OpenSuSE running 3.0.0 rc 42 compiled with gcc 4.1.0. 
Configure was run as ./configure --prefix=/usr/local .  I'm under the impression 
that collecting with 3.0.0 from a 2.0.6 argus should work fine.  Carter, please 
correct me if I am wrong.

Collection has been stable and working fine.  I do post collection processing of 
the data to give me TopN type stats, along the lines of what Carter posted 
recently with racluster | rasort | ra.  I have run into some racluster issues.

First - a seg fault.  The command that sees the segfault is   racluster -M rmon 
-m saddr -r ... -w ...  .  Attached is sample data (segfault.dat) that causes 
the fault.  Seg fault was at common/argus_client.c:9535, but the fix looks to be 
common/argus_client.c:9505

switch (type = f1->hdr.argus_dsrvl8.qual & 0x07)

Changing to

switch ((type = f1->hdr.argus_dsrvl8.qual) & 0x07)

appears to fix the bug.  The output seems right, but I haven't dug into it in 
detail to ensure that there aren't minor discrepancies.

Second - things seem to go wrong after getting rtcp data.  Attached is sample 
data (rtcp-argus.dat) that causes this problem.

Apologies for the line wraps.

We should see data for the IP addresses above 62.236.60.53 here, but it isn't 
there.  If I recall correctly, on large input files, I see small, truncated 
output files from racluster as soon as I hit a record for rtcp.

0.0.0.0               3        222   RSP

07/04/02 23:55:06              ip      154.20.43.121          <-> 
0.0.0.0              10       1081   CON

Ignoring rtcp records gives me complete output for non-rtcp records.

I am currently working around this issue by using the 'not rtcp' filter on my 
racluster command lines.  I haven't looked for a fix for this one.
