I have an OpenVPN server running on OpenBSD 3.8 (x86). I've been having intermitten problems with it and reconnection problems. It's openvpn out of ports for 3.8.
I have it down to right now, sporadically, the OpenVPN server thinks it is sending UDP packets (and in the logs makes note that it has) but I cannot see them leaving the external interface... What can I do to track down where this is going wrong? Is there some way to see if OpenBSD is taking this packet and then losing it? I am just not sure where to look next. I've watched it happen, and the traffic is very low, the utlization is like so: load averages: 0.40, 0.54, .60 38 processes: 37 idle, 1 on processor CPU states: 2.7% user, 0.0% nice, 3.7% system, 1.6% interrupt, 92.0% idle Memory: Real: 678M/824M act/tot Free: 684M Swap: 0K/3072M used/tot The strange part is that it works fine for a while, then suddenly starts up with this behavior... We've had this happen with clients on all different platforms (windows / mac / linux). We have an upgrade to OpenBSD 4.0 set for the first few weeks of next year... I've another 3.8 machine running this fine with no problems whatsoever... Any pointers would be great and very appreciated. I've tried the OpenVPN lists, but no help there OpenBSD 3.8 (GENERIC) #138: Sat Sep 10 15:41:37 MDT 2005 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Celeron(R) CPU 2.40GHz ("GenuineIntel" 686-class) 2.41 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,CNXT-ID real mem = 1609588736 (1571864K) avail mem = 1461350400 (1427100K) using 4278 buffers containing 80580608 bytes (78692K) of memory mainbus0 (root) bios0 at mainbus0: AT/286+(49) BIOS, date 05/19/04, BIOS32 rev. 0 @ 0xfd5b6 pcibios0 at bios0: rev 2.1 @ 0xfd520/0xae0 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfde80/352 (20 entries) pcibios0: PCI Interrupt Router at 000:31:0 ("Intel 82371FB ISA" rev 0x00) pcibios0: PCI bus #3 is the last bus bios0: ROM list: 0xc0000/0x9000 0xc9000/0x1000 0xca000/0x1000 0xcb000/0x1800 cpu0 at mainbus0 pci0 at mainbus0 bus 0: configuration mode 1 (no bios) pchb0 at pci0 dev 0 function 0 "Intel 82875P Host" rev 0x02 ppb0 at pci0 dev 3 function 0 "Intel 82875P PCI-CSA" rev 0x02 pci1 at ppb0 bus 1 em0 at pci1 dev 1 function 0 "Intel PRO/1000CT (82547GI)" rev 0x00: irq 5, address: 00:09:6b:7f:70:93 ppb1 at pci0 dev 28 function 0 "Intel 6300ESB PCIX" rev 0x02 pci2 at ppb1 bus 2 em1 at pci2 dev 2 function 0 "Intel PRO/1000MT (82546GB)" rev 0x01: irq 5em1: The EEPROM Checksum Is Not Valid em1: Unable to initialize the hardware em2 at pci2 dev 2 function 1 "Intel PRO/1000MT (82546GB)" rev 0x01: irq 5em2: The EEPROM Checksum Is Not Valid em2: Unable to initialize the hardware uhci0 at pci0 dev 29 function 0 "Intel 6300ESB USB" rev 0x02: irq 11 usb0 at uhci0: USB revision 1.0 uhub0 at usb0 uhub0: Intel UHCI root hub, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered uhci1 at pci0 dev 29 function 1 "Intel 5300ESB USB" rev 0x02: irq 5 usb1 at uhci1: USB revision 1.0 uhub1 at usb1 uhub1: Intel UHCI root hub, rev 1.00/1.00, addr 1 uhub1: 2 ports with 2 removable, self powered "Intel 6300ESB WDT" rev 0x02 at pci0 dev 29 function 4 not configured "Intel 6300ESB APIC" rev 0x02 at pci0 dev 29 function 5 not configured ehci0 at pci0 dev 29 function 7 "Intel 6300ESB USB" rev 0x02: irq 11 usb2 at ehci0: USB revision 2.0 uhub2 at usb2 uhub2: Intel EHCI root hub, rev 2.00/1.00, addr 1 uhub2: 4 ports with 4 removable, self powered ppb2 at pci0 dev 30 function 0 "Intel 82801BA AGP" rev 0x0a pci3 at ppb2 bus 3 vga1 at pci3 dev 2 function 0 "ATI Radeon VE QY" rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) fxp0 at pci3 dev 8 function 0 "Intel 82557" rev 0x0c, i82550: irq 11, address 00:0e:0c:50:d7:c4 inphy0 at fxp0 phy 1: i82555 10/100 PHY, rev. 4 ichpcib0 at pci0 dev 31 function 0 "Intel 6300ESB LPC" rev 0x02 pciide0 at pci0 dev 31 function 2 "Intel 6300ESB SATA" rev 0x02: DMA, channel 0 configured to compatibility, channel 1 configured to compatibility atapiscsi0 at pciide0 channel 0 drive 0 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0: <HL-DT-ST, CD-ROM GCR-8482B, 1.02> SCSI0 5/cdrom removable cd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 2 wd0 at pciide0 channel 1 drive 0: <Maxtor 6Y080M0> wd0: 16-sector PIO, LBA, 76324MB, 156312576 sectors wd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 5 "Intel 6300ESB SMBus" rev 0x02 at pci0 dev 31 function 3 not configured isa0 at ichpcib0 isadma0 at isa0 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 pmsi0 at pckbc0 (aux slot) pckbc0: using irq 12 for aux slot wsmouse0 at pmsi0 mux 0 pcppi0 at isa0 port 0x61 midi0 at pcppi0: <PC speaker> spkr0 at pcppi0 sysbeep0 at pcppi0 lpt0 at isa0 port 0x378/4 irq 7 npx0 at isa0 port 0xf0/16: using exception 16 pccom0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo pccom1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo fdc0 at isa0 port 0x3f0/6 irq 6 drq 2 fd0 at fdc0 drive 0: 1.44MB 80 cyl, 2 head, 18 sec biomask ef65 netmask ef65 ttymask ffe7 pctr: user-level cycle counter enabled dkcsum: wd0 matches BIOS drive 0x80 root on wd0a
