I don't think Como on 64bit OS has ever been tested. I'm not surprised of seeing weird behaviors...

Subject: [como-devel] Como on x86_64

Hello,

I am trying to run CoMo v1.5 on a system with a:
- 64bits processor : Dual-Core AMD Opteron 2222  and
- kernel: Linux 2.6.26-2-amd64 #1 SMP Thu May 28 21:28:49 UTC 2009 x86_64 GNU/Linux.

The installation works without problems, but, when I am trying to analyze a pcap trace file (example-trace.pcap) it doesn't read any packet, and I can't see any error in the log:

$ /usr/local/bin/como -c como.conf

I observed that soon after the launching como, one processor arrives at 100% and stays blocked there.

Anyway, when I am trying to capture packets from eth0 with the libpcap sniffer it works perfectly fine.

Do you have any idea why I am getting this behavior?

Thanks,
Oana
