I'm not on these lists. I've just got my V34 leased line installed, and I'm trying to configure my FreeBSD 2.0.5 gateway to use it. I've tried both pppd and ppp, and none of this come with enough documentation about leased line operations. I'd prefer to stay with PPP, but if you can suggest a quick configuration using SLIP, I'd be willing to try it (at least temporarly). My ISP has a CISCO router, if that matter. We have a full class "C" address, plus one external address to use for the PPP port, provided the latter is mandatory. We have been using iijppp over a dial up connection with the same ISP for more than 6 months: I've tried to adapt the previous configuration, without luck: it logs hand-triggered line drops (DCD level change detection ?), but it never connects. I run ppp -dedicated, but it's not clear what this option is meant for. Of course, the modems speak to each other: they connect correctly at 28.8 (I can see it if I run tip on that serial port). Please, if you have some experience with leased lines, feel free to ask anything you may need to diagnose my problems. Failure reports also welcome: better to know what to avoid.... If this is not a task I can solve with this release of FreeBSD, I can try and find something else, while waiting for further development. Thanks in advance.

Sender: owner-isp@FreeBSD.org Precedence: bulk I'm seeing a fairly significant bug in FreeBSD's networking code w/regards to routing and arp, and I'm looking for someone who can help me figure this out. I've asked Garrett to help, but he has been too busy so I'm now looking for someone else who is familiar with the networking code in FreeBSD. I can re-produce the problem at will and can tell whomever helps me how to re-create it. I'm suprised that none of the ISP's have seen this, but I suspect they aren't using proxy-arp, or aren't seeing folks re-connect from broken PPP connections as fast as we do. Basically, I'm using proxy-arp to setup routing from a couple 'portable' computers which can exist on either our local network, or at home. I'm using the same IP address for both locations, and I'm using proxy-arp to allow the machines to sit behind our PPP server (a FreeBSD box). When the line goes down and the remote machines are talking with a machine on our local network, the PPP process (correctly) removes the proxy-arp entry from the PPP server. However, packets are still being sent to that box from other machines on our network, which causes the server box to send out an arp request onto the ethernet and add an incomplete arp entry and route to the ethernet. This is acceptable *except* that the remote box re-connects to the server, which causes PPP to proxy-arp again for the remote box. What *should* happen is the incomplete arp entry and route should be removed from the tables and replaced with the now valid proxy-arp entry. What is happening is the proxy-arp entry is added to the table *after* the incomplete arp entry, so the server machine doesn't know to route traffic to the remote machine via the PPP link. PPP is doing the correct thing, and the remote machine is sending data to the server, but the server doesn't know the correct route to get back to it since it assumes the route is via the ethernet. This problem occurs with normal arp as well as proxy-arp, so you can have up to three arp entries for a single IP address in the arp table. Here's what happens on my server box right now. ws1.sri.MT.net (204.182.243.100) at (incomplete) ws1.sri.MT.net (204.182.243.100) at 0:80:48:e8:27:63 permanent published ws1.sri.MT.net (204.182.243.100) at 0:80:48:e8:27:63 permanent published (proxy only) Fun, huh? I've got kernel dumps where the bogosity is occuring, back-traces, and all sorts of programs to trigger the bug and more information than you'll ever want to describe the problem, but I'm beating my head against the wall trying to figure out the code flow, so I'm appealing the BSD gurus to help. This problem won't occur if the arp entries time-out on both the remote host and the server box. If that happens, then the proxy-arp entry which gets added by PPPD is the first in the arp table, and routing is correct until the line goes down. I've checked and neither SunOS 4.1 nor Solaris 2.4 have this bug, and I don't have root access on any other OS's to test this out. Please help!

I've been noticing this yesterday, too. Garrett solved the problem for the non proxy-arp case right before 2.1 (where a clone route has been allocated through the default route, pointing to the ethernet interface), but this one here is still broken.

Basically packets would go another way that what "netstat -rna" would make you think. Sometimes I could clear the trouble by zapping all arp-entries.

Umm, I'm not seeing that fix on my 2.1 box (which is running post 2.1 stuff including fixes that came in after the fact), and I don't remember the fix going in. I just perused the commitlog file and I'm not seeing any 'arp' fix, although I'm looking at the clone route stuff. > > Anyway, the location > > where the clone routes are being killed might be a good spot to check > > for the ARP stuff. I'll look, but as you could see from my original message, I'm seeing the same problem with the regular arp as well as proxy-arp, so it's not fixed for the non proxy-arp case. > I have seen the same kind of trouble with arp, ipfw and routed. > > Basically packets would go another way that what "netstat -rna" would > make you think. > > Sometimes I could clear the trouble by zapping all arp-entries.

Unfortunately, that's not a solution given that the boxes can exist on the local ethernet and come in via PPP (portables are great fun).

No, but it's probably something we can use as a data-point to find out what's going on. The thing I don't like is that packets get routed counter to what "netstat -rna" & "arp -a" reports. In my case packets were sent out a wrong interface even. So we are talking about some pointer which ends up pointing to the wrong arp-entry I think. Maybe that could be a/the hint. -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@ref.tfs.com TRW Financial Systems, Inc.

(203.14.159.255) at (incomplete) (FreeBSD 2.0.5-RELEASE) That last entry bugs me a bit too: I've never seen any other system trying to ARP for the broadcast address. Each of those hostnames represents a dial-up SLIP site (using /usr/sbin/sliplogin). I actually add proxy ARP entries for them at boot time, using a shell script which goes through my slip.hosts file and adds an ARP entry for each valid host. delta and master seem to have the problem you describe above. saturn seems completely different (read: inconsistent): It has been added to the ARP table at exactly the same time as all the others, but it shows up as "(proxy only)". Bizarre. I think proxy ARP on FreeBSD is bogus :-) The wierd thing is that when these hosts login they *work*. You're seeing a manifestation of the problem which doesn't work; I'm seeing one where it doesn't seem to affect operation (even though it's dead wrong).

Hmm - For PPP sites I use ijppp. The only permanent proxies in my ARP table are for SLIP sites. I wonder if the thing that's stopping it from working for you has something to do with the way pppd handles proxy ARP? - mark --- Mark Newton Email: newton@communica.com.au Systems Engineer Phone: +61-8-373-2523 Communica Systems WWW: http://www.communica.com.au
