(obviously files are not exactly same as streamed packets are encapsulated in TZSP, therefore almost twice as large) And it is quite hard to debug VLANs when I can't trust sniffed packets. streaming and displaying live packets with wireshark is much faster than sniffing it to router, then downloading the file and opening it later. sp=sharing (I can't upload it to this forum - unsupported format) I tried several times, with both CHR and physical router, capturing different interfaces, capturing everything - in all cases, half of packets is always streamed without VLAN.įeel free to observe my PCAP files. This code should obviously produce two same results - save the data straight in the router to "vlan.pcap" and at the same time stream data to my desktop (where is already wireshark capturing it) sed -r -e 's,eth(0|1)(:)?: PACKET SNIFFER\((/sbin/dhclient3|/usr/sbin/dhcpd3)\+\]\),eth\: PACKET SNIFFER\(\),' \īe careful to leave the backslash at the end of the line.Set file-name=vlan.pcap filter-interface=eoip-chr-trunk filter-mac-address=00:15:5D:C9:30:09/FF:FF:FF:FF:FF:FF filter-operator-between-entries=and streaming-enabled=yes streaming-server=10.245.24.67 To fix this issue, make a backup copy of /etc/cron.daily/chkrootkit then edit it and change. But the chkrootkit package maintainers never updated /etc/cron.daily/chkrootkit to work with version 4 series of the isc-dhcp-client and isc-dhcp-server packages, whose files don't have the version number. This is because on Debian, the binaries from these packages used to end with a version number, e.g. However, the workaround for the false positive doesn't work.
The chkrootkit package's /etc/cron.daily/chkrootkit script has a workaround for this which tries to replaces the PID with a static string.
The isc-dhcp-client and isc-dhcp-server packages (DHCP client and server) re-runs their daemons regularly and cause a "packet sniffer" false positive.
