From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; SunOS 5.8 sun4u) Description of problem: libpcap code in RH 7.2 seems to have an error. In tcpdump you can see the problem: command: ./tcpdump -n -i eth0 ...some data.... -2147415483 packets received by filter -1073744432 packets dropped by kernel This is in libpcap, not tcpdump AFAIK because other apps, such as argus (http://www.qosient.com) linked against libpcap have no problem. Also, I deinstalled RH libpcap and insatlled the version (made from source) from tcpdump.org and everything worked fine on argus. I reproduced the problem rebuilding tpcdump.src.rpm from scratch, so it's not just a binary issue...it's somewhere (probably) in the RH patches. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. See above. 2. 3. Actual Results: negative byte counts in output of tcpdump. libpcap related. Expected Results: negative byte counts don't make sense. should be positive. Additional info: Note this isn't just an uninit int error...other applications linked against RH libpcap will not work from mysterious errors. Once libpcap was replaced with the version from tcpdump.org, those errors go away.
