Weird ping times

I rebooted the machine to no effect. The problem seems to go away on its own for a few hours & then comes back. I ran tcpdump & saw nothing different between the times this behaviour was seen & the times it wasnt. The machine is running IPFW, isc-dhcp server and nat.

Re: Booting from a flash card
I have been using http://www.gctglobal.com/Products/Set_Top_Box/STB6086N2/stb6086n2.html. They have CF slot that the BIOS recognizes as a boot device. . Lowell Gilbert wrote: Jamie Ostrowski <[EMAIL PROTECTED]> writes: I've got a Ricoh (Ricoh RL5C475 PCI-CardBus Bridge) with a 1Gb PCMCIA Compact Flash card. I'd like to install FreeBSD on the flash card and to be able to boot with the flash. The problem I am running into is that my BIOS doesn't recognize the flash card as a boot device. Is there any way to run with a FreeBSD system (4.11) off of a flash card rather than a hard drive? Any way to boot up with the flash card? The BIOS has to initiate the booting. If the system can't boot off of flash, you need to start the boot off some other device, and then you will be able to run some kind of boot management from the other device. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" -- Karan Gupta /--- / /EdgeFocus Inc/ /Cell: (949) 202-9797 / /Main: (949) 417-3360 x 250 / /Fax: (949) 417-3371 / /17981 Skypark Cr.

Cant locate system disk
Im trying to install fBSD 5.4 onto a Maxtor N256 10GB hdd. I have the hdd hooked up as a primary master, the cdrom as secondary master. The cdrom is the 1st boot device & the hdd the second. When I put in the fBSD firstdisk.iso into the CD, it finds the hdd...installs the boot manager, partitions it & installs to the point where it says "Congratulations". It asks me to enter some config info. Everything looks good so far. When I remove the cdrom and boot from the hdd i get " system disk boot failure. Insert system drive" thoughts? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

using ipfw
Newbie here so pls excuse if this question sounds trivial i use a single bsd router to service 2 properties. I want ppl on prop A to get 1.024kbit/s and the ones on prop B to get 256kbit/sprop B is connected on the same network as prop A using a wireless device that has the an IP within the network range. Can is add a pipe to limit data from the IP address of the wireless device to 256kbit/s & achieve what i desire?
