Re: Problem with: OSPF thru netgraph & Gif Tunnels
Chris Bose wrote: Hi All, I’m trying to setup a network between two locations over a WAN and I’m running into a wall when I try to get OSPF to talk over my WAN tunnel. I’ve realized that I’m not smart enough and need your help. The problem is as follows: My network consists of the following: Site A connects together with a few quagga routers on freebsd 4.8 Site A: Router 1: FXP0 (10.1.1.1/24) Router 1: FXP0 (10.1.2.1/24) Router 1: FXP0 (10.1.3.1/24) Router 1: GIF0 (10.1.4.1 -> 10.2.4.1) Site B connects to site A by using the GIF interface over the public network "public network" == Internet right? SiteB: Router 2: FXP0 (10.2.1.1/24) Router 2: FXP0 (10.2.2.1/24) Router 2: FXP0 (10.2.3.1/24) Router 2: GIF0 (10.2.4.1 -> 10.1.4.1) I run OSPFv2 (quagga) at Site A and at Site B. There is no problem connecting site A & B together via OSPF over the GIF0 tunnel. Essential OSPF multicasts its route advertisements thru the GIF tunnel to the other side. This works fine because the OSPF router and the GIF tunnel are both on the same freebsd computer With such a simple network, why not use static routing? Now here is what I’m trying to do to setup site C. At site C I need to separate this into two computers. One computer will terminate the GIF tunnel and the other computer runs the OSPF router. why do you "need" to do this? So the setup between A and B looks like this: SiteA:Computer 1 SiteB:Computer 2 (OSPF + GIF0) == (GIF0 + OSPF) And setup between Site B and C looks like this: SiteB:Computer 2 SiteC:Computer 3 SiteC:computer 4 (OSPF + GIF1) == (GIF1) -(OSPF) === denotes GIF tunnel --- denotes normal Ethernet connection Computer 3 has two ethernet interfaces The problem that I have is I can’t get Computer 4 to communicate to computer 2 thru the GIF. The computers can ping each other, but the OSPF multicast packets don’t go thru. do the packets get as far as computer 3? I'm not an expert in multicast, but what in teh setup makes you think that the multicast packets SHOULD be sent through the tunnel? I have tried IPFW fwd commands on computer 3 I'm not sure that forwarding works for non-tcp traffic. Certainly that is true for local forwarding. Ifpw fwd computer 2 ip from computer 4 to any But that didn’t work I’ve tried Ethernet bridging… but bridging doesn’t work on a Gif interface. I’ve tried to replace the gif tunnel with Netgraph UDP tunnel, but I can’t use that in the bridge either. Interesting.. You should be able to make it work by using an ng_eiface instead of an ng_iface node for the tunnel, so that you are tunnelling ethernet packets instead of ip packets, then on the far end you can feed them straight into the bridge node. though you don't really understand where bridging comes into it in the first place. You have different subnets so you should be routing and not bridging. I use UDP netgraph tunnels all the time. sometimes encrypted by using IPSEC on the UDP packets connecting an iface node to a ksocket(udp) node. I also sometimes use mpd to encapsulate ppp instead of plain ip, and use it's udp transport method to do the work (When I want to bond several links into one tunnel using multilink ppp) I have NEVER however had experience with multicast and tunnels. I used the sample in /src/examples/netgraph/bridge. but you are not using a bridge.. are you? I have not tried L2TPv3… So my question is how to get the above configuration working. I think this should be really simple to do, it’s a typical configuration as far as I can tell. Please show your ingenuity with your reply. I really appreciate it. I tried to make the example generic without any configuration files because there is nothing specific about my configuration. Please post your own configuration for the above if applicable. You can assume that I have a virgin computer and I can configure it any which way I want. If you need me to give you any configuration please let me know. If you want me to post a better network diagram please let me know as well. Many thanks, Chris. __ Do You Yahoo!? Tired of spam? Yahoo!

I haven't looked in depth at the information but it sounds to me as though the most likely failure mode is that multicast isn't working over the gif tunnel for whatever reason. You could try configuring OSPF in NBMA mode over the tunnel, that way OSPF discovery isn't dependent upon multicasts being forwarded over the tunnel, but requires you to explicitly specify the OSPF peers at either end.

And what I need is to find out whether the expression is true or not. My question is, is there an expression processing library that can handle complex equations easily? -Ron __ Do You Yahoo!?

There seems to be a size limitation in the loader (and pxeboot since it is built using loader code). I've tried loading through pxeboot + TFTP : the tftp pxeboot client is limited to 32MB unfortunately (BTW : the one of the tftp port works fine). I tried to use pxeboot + NFS, kernel hangs because of loader limitation (BTW : you can use only NFS UDP since the pxeboot NFS client don't do TCP which means booting using this this technique using TFTP is not less reliable than NFS). I even tried pxegrub, but again it's the loader ... It seems the only reasonable solution is to make a small jumpstart mfsroot, make a md device (malloc / ..) with any size you want as long as you have enough memory (even 1GB+) and then fetch the mfsroot image using tftp/nfs/scp/.. and chroot to it.

My dvd (and that >of my friend's, I tested) both immediately choke on trying to play this Sorry, can't help with your original question, but I can help with the choice of DVD players. Phillips makes a good reprogrammable one. I think the model is called 642 in US and 630 in Europe, I can look at mine (US) at home. Walmart and Target sell them for shomething like $70. Changing the region code is a breese - you get the tray open, press the "secret" button sequence and can enter the new code. Setting the code to 0 would make it region-free and would play any disks except the very paranoid ones. For those you can change it back to 1 or 2. >disk, they don't even open a menu. I need to change that encoded region >value from 2 to 1. Having software here that coded, say, a null value AFAIK it's done in a more interesting way: the region code on CD is actually a small interpreted bytecode program that reads the player's configuration data with the region code in it and decides if it wants to play on this player or not. That's why some disks won't work with the players having region 0. I'd guess that this program can be happily amputated altogether. -SB ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

By the looks of pwrite() and writev() it could probably be implemented fairly easily; it would largely be a matter of rototiling pwrite() to accept an array of iovecs, as writev() currently does, as pwrite() already knows how to pass a single uio/iovec on the stack with the desired start offset. Looking at the man page for pwritev() it only accepts a start offset, rather than an individual offset for each scatter/gather element.

Ok, something like this ?
I'm a bit puzzled by the coding style in the file, but I think I got the
spirit of it. ;-)
Possibly more of dofileread() and dopreadv() and their write-cousins
could be merged into each other, but this patch is better readable...

Well (to put that to rest), there are two types of region coding in use on DVDs. The first is the one we're talking about here ... which is a code in the files that tells the DVD player which region the disk is. Early "unlocked" players were simply patched to accept any region. The second type is code in the menu system that queries the region code and then acts on it. Early players returned '0' for this function ... and the disks were coded to not play. The fix for this was players that you could change the region on ... and "unlocked" players of this type allow you to set the region an unlimited number of times. "locked" players usually let you set the region some small number of times.

Or should I combine all of the 4 read functions together (as well as all of the 4 write functions) ? The current patch is against 6-CURRENT, but applies almost perfectly against 5-STABLE as well, and works for me. ;-) Marc pgpCBcJPHwAma.pgp Description: PGP signature
Trouble with 250G SATA drive?
Hi all, I've just bought a Seagate 250G SATA drive to run in a shared desktop at home. It should have 3 boot partitions: 16M FreeBSD 5, 16M linux, 32M NTFS for Windows XP. The remaining wil be formatted with FAT32 to be used as a common data for the 3 operating systems. Well, everything seemed to be fine. I copied the FreeBSD partition from the previous installed disk with dump(8), and installed XP from CDs. But suddenly, the data and NTFS partitions began to disappear. I don't know exactly what were the steps used to crash the disk, but it happened at least 3 times, after 3 full windows installs (which are not quick, for my sadness). In the last one I could almost detect it. I finished the initial windows instalation, and booted into FreeBSD to make sure the NTFS and FAT partitions were available. They seemed to be. Then I reboot into windows, and it crashed, with a missing HAL.DLL. Boot again into FreeBSD, and the NTFS partition still seemed ok. But I gone into the \WINDOWS\system32, and did an ls. The kernel pushed some errors with "bad magic" or something like that, and the file system locked. Also, the boot information for the first FAT32 partition has been completely destroyed, leaving it unreadable. The mainboard is an ASUS K8V, with 1G RAM. I'm running the 32 bit version of FreeBSD, although it is an AMD64 machine. The 250G SATA disk is on the promise RAID, and I have another PATA 120G on the promise RAID, and a 40G PATA on standard IDE. I already had a problem with a previous ASUS board in which the promise raid could not deal with disks bigger than 120G. The symptons were very similar. Could this be the problem? Does somebody know if FreeBSD or mount_ntfs has any kind of disk size limitation in this hardware? Oh, I did remember now that I was using mount_ntfs -o noatime, if that matters. Thanks for any help, Jonny PS: Now it has been fully reformatted with no NTFS, using FAT32 instead. But I'm afraid of getting into FreeBSD again in this machine. Please help! :-( ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
