openbsd and ethernet tap (port replication)
Hello, I am trying to replicate some traffic from a Cisco 6500 onto an OpenBSD 4.5 vanilla machine. I have two NICs, rl0 which is the administration interface and em0 which I hope to use for the ethernet tap. So far, my cisco replicates traffic happily, i can see the packet count in/egress increasing but nothing seems to reach em0. I have no PF running, the box is inside the network with a cable connected straight from em0 to a cisco port on the 6500. The cisco router reports the link live (so does OpenBSD) but no traffic seems to be flowing. I realize that has to be something stupid but if anyone could send me a pointer, that would be most welcome. em0: flags=8802BROADCAST,SIMPLEX,MULTICAST mtu 1500 lladdr xx:xx:xx:xx:xx priority: 0 media: Ethernet autoselect (1000baseT full-duplex,rxpause) status: active OpenBSD 4.5 (GENERIC) #1749: Sat Feb 28 14:51:18 MST 2009 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) 4 CPU 3.20GHz (GenuineIntel 686-class) 3.22 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,CNXT-ID,xTPR real mem = 1073246208 (1023MB) avail mem = 1029500928 (981MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 01/19/04, BIOS32 rev. 0 @ 0xfb1a0, SMBIOS rev. 2.3 @ 0xf0120 (49 entries) bios0: vendor Award Software International, Inc. version F5 date 01/19/2004 bios0: NEC Computers International 000 acpi0 at bios0: rev 0 acpi0: tables DSDT FACP APIC acpi0: wakeup devices USB0(S3) USB1(S3) USB2(S3) AMR0(S4) UAR1(S4) UAR2(S4) PCI0(S4) acpitimer0 at acpi0: 3579545 Hz, 24 bits acpimadt0 at acpi0 addr 0xfee0: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: apic clock running at 200MHz ioapic0 at mainbus0: apid 2 pa 0xfec0, version 14, 24 pins ioapic0: misconfigured as apic 0, remapped to apid 2 acpiprt0 at acpi0: bus 0 (PCI0) acpicpu0 at acpi0 acpibtn0 at acpi0: PWRB bios0: ROM list: 0xc/0x8000 0xc8000/0x8000! 0xd/0x1800 0xd2000/0x1000 pci0 at mainbus0 bus 0: configuration mode 1 (bios) pchb0 at pci0 dev 0 function 0 SiS 648 PCI rev 0x51 sisagp0 at pchb0 agp0 at sisagp0: aperture at 0xe000, size 0x800 ppb0 at pci0 dev 1 function 0 SiS 648FX AGP rev 0x00 pci1 at ppb0 bus 1 pcib0 at pci0 dev 2 function 0 SiS 85C503 System rev 0x14 SiS 7007 FireWire rev 0x00 at pci0 dev 2 function 3 not configured pciide0 at pci0 dev 2 function 5 SiS 5513 EIDE rev 0x00: 648: DMA, channel 0 wired to compatibility, channel 1 wired to compatibility pciide0: channel 0 disabled (no drives) wd0 at pciide0 channel 1 drive 0: SAMSUNG SP2014N wd0: 16-sector PIO, LBA48, 190782MB, 390721968 sectors wd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 5 auich0 at pci0 dev 2 function 7 SiS 7012 AC97 rev 0xa0: apic 2 int 18 (irq 9), SiS7012 AC97 ac97: codec id 0x414c4760 (Avance Logic ALC655 rev 0) audio0 at auich0 ohci0 at pci0 dev 3 function 0 SiS 5597/5598 USB rev 0x0f: apic 2 int 20 (irq 5), version 1.0, legacy support ohci1 at pci0 dev 3 function 1 SiS 5597/5598 USB rev 0x0f: apic 2 int 21 (irq 10), version 1.0, legacy support ohci2 at pci0 dev 3 function 2 SiS 5597/5598 USB rev 0x0f: apic 2 int 22 (irq 11), version 1.0, legacy support ehci0 at pci0 dev 3 function 3 SiS 7002 USB rev 0x00: apic 2 int 23 (irq 6) usb0 at ehci0: USB revision 2.0 uhub0 at usb0 SiS EHCI root hub rev 2.00/1.00 addr 1 vga1 at pci0 dev 9 function 0 S3 Trio32/64 rev 0x54 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) em0 at pci0 dev 11 function 0 Intel PRO/1000MT (82540EM) rev 0x02: apic 2 int 19 (irq 10), address 00:07:e9:39:50:d5 rl0 at pci0 dev 15 function 0 Realtek 8139 rev 0x10: apic 2 int 16 (irq 11), address 00:0d:61:1b:69:27 rlphy0 at rl0 phy 0: RTL internal PHY isa0 at pcib0 isadma0 at isa0 com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo com1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo pckbc0 at isa0 port 0x60/5 pckbd0 at pckbc0 (kbd slot) pckbc0: using irq 1 for kbd slot wskbd0 at pckbd0: console keyboard, using wsdisplay0 pcppi0 at isa0 port 0x61 midi0 at pcppi0: PC speaker spkr0 at pcppi0 lpt0 at isa0 port 0x378/4 irq 7 it0 at isa0 port 0x2e/2: IT8705F rev 2, EC port 0x290 npx0 at isa0 port 0xf0/16: reported by CPUID; using exception 16 usb1 at ohci0: USB revision 1.0 uhub1 at usb1 SiS OHCI root hub rev 1.00/1.00 addr 1 usb2 at ohci1: USB revision 1.0 uhub2 at usb2 SiS OHCI root hub rev 1.00/1.00 addr 1 usb3 at ohci2: USB revision 1.0 uhub3 at usb3 SiS OHCI root hub rev 1.00/1.00 addr 1 mtrr: Pentium Pro MTRR support uhidev0 at uhub1 port 1 configuration 1 interface 0 Sun Microsystems Type 6 Keyboard rev 1.10/2.00 addr 2 uhidev0: iclass 3/1 ukbd0 at uhidev0: 8 modifier keys, 6 key codes, country code 33 wskbd1 at ukbd0 mux 1 wskbd1: connecting to wsdisplay0 softraid0 at root root on wd0a swap on wd0b dump on wd0b Cheers, Steph
