Both use the netmask of 255.255.255.0. The subnets were each on their own physical LAN segments. RIP worked fine for this small network. I use routed -s (and have also used gated just to play with it.) Now, I lost one of the physical subnets. I physically have both 10.97.8.0 and 10.97.88.0 on the same physical segment. I've modified the configuration to use an alias. Now I can't seem to get routed (or gated) propagate routing information for the subnet configured via the alias. rc.conf was: ifconfig_vx0="inet 10.97.8.0 netmask 255.255.255.0" ifconfig_fxp0="inet 10.97.88.0 netmask 255.255.255.0" now: ifconfig_vx0="inet 10.97.8.0 netmask 255.255.255.0" ifconfig_vx0_alias0="10.97.88.0 netmask 255.255.255.0" I also tried using a netmask of 255.255.255.255 but 1) this doesn't work either and 2) I don't believe it is what I need anyway. I do not want another host entry on the same subnet, I want to "multinet" two subnet networks on the same physical Ethernet and route between subnets. Is this supposed to even work (i.e. is multinetting even supported in FreeBSD)? If so, is anyone else doing it and can you suggest what I might be doing wrong? Thanks, MikeC Michael C.

Now I think I'll change it, but it's working fine. I had a problem with ifconfig_if0_alias, originally and I am bringing them up with a seperate script that is just ifconfig vx0 inet 10.97.8.0 netmask 255.255.255.224 alias ifconfig vx0 inet 10.97.88.0 netmask 255.255.255.0 alias I use this example because one is a /27 subnet and the other is a class C. Should work fine. This machine is a gateway between four networks and the internet so I haven't even added static routes:-) ed > > > I also tried using a netmask of 255.255.255.255 but 1) this doesn't work > either and 2) I don't believe it is what I need anyway.

This chip sucks, but that's not why I'm writing. Today, while running some tests, I noticed some odd IP fragmentation behavior which I thought was due to a bug in my driver code, but I've since been able to duplicate the problem on another machine with a 3c509 card using the ep driver. This has me a little confused. Here's the deal: one of the tests I do involves sending ICMP datagrams with ping using various payload sizes (using the -s flag). By using a packet size larger than 1500 bytes, I can get the system to queue up a small number of ethernet frames fairly quickly and observe the result. This lets me see if the driver is transmitting rapidly queued sequences of frames correctly. I use the -c flag with ping to limit the number of packets so that I can check short bursts of frames rather than a huge stream. (Watching a massive bunch of frames fly through tcpdump at 100Mbps makes it hard to spot glitches.) One thing I do a lot is this: # ifconfig 10.0.0.2 netmask 0xffffff00 up # ping -c 1 -s 4096 10.0.0.1 10.0.0.1 is another machine attached to the interface under test using a crossover cable. I run tcpdump on this host to monitor traffic from the first machine so I can see what the NIC is sending. Assuming the system has just been booted, the 10.0.0.2 host will not yet have an ARP entry for the 10.0.0.1 host, so the sequence should go something like this: 10.0.0.2: sends an ARP request for 10.0.0.1 10.0.0.1: sends an ARP reply to 10.0.0.2 10.0.0.2: sends the first fragment of an ICMP echo request which should be about 1514 bytes long. The ICMP packet is fragmented since 4096 bytes is larger than the interface MTU of 1500 bytes. 10.0.0.2: sends the next fragment, also of 1514 bytes 10.0.0.2: sends the last fragment, somewhere in the neigborhood of 1068 bytes 10.0.0.1: sends the first fragment of an ICMP echo reply. Again, the fragmentation occurs because the reply is also 4096 bytes. 10.0.0.1: sends the next frag 10.0.0.1: sends the last frag At this point, ping reports that the reply was received and all is happy and there is much rejoicing. Not. What I observed is that the ARP request and ARP reply proceed as expected, but the first portion of the ICMP packet transmitted is in fact the last fragment. The first two fragments have been vanished into the void. Since the ICMP echo request is contained in the first fragment, the host on the other side discards the fragment and never sends a reply. The result is that 'ping -c 1 -s 4096 10.0.0.1' just sits there and no reply is ever received. On the other hand, sending a second ICMP request immediately after the first does work. Below is a tcpdump capture of an actual exchange between two machines. Harpsichord is a Micron Pentium Pro 200Mhz machine with a 3Com 3c509 ethernet adapter running FreeBSD 2.2.6. Sax is an IBM RS/6000 model 390 running AIX 4.1.4. First, I run tcpdump on harpsichord to capture the session: [/homes/rwpaul]:harpsichord{1}# tcpdump -n -e -i ep0 host sax and harpsichord tcpdump: listening on ep0 Now I type 'ping -c 1 -s 4096 sax' on harpsichord. Note: there is no ARP entry for sax on harpsichord at this point. The resulting exchange is shown below: 21:41:03.105011 0:60:97:6c:6f:b0 ff:ff:ff:ff:ff:ff 0806 42: arp who-has 128.59.68.56 tell 128.59.68.72 21:41:03.105338 10:0:5a:fa:4e:9e 0:60:97:6c:6f:b0 0806 60: arp reply 128.59.68.56 is-at 10:0:5a:fa:4e:9e 21:41:03.105970 0:60:97:6c:6f:b0 10:0:5a:fa:4e:9e 0800 1178: 128.59.68.72 > 128.59.68.56: (frag 15401:1144@2960) Note that the only part of the ICMP datagram to make it out the door is the final fragment. This fails to illicit a response from the RS/6000, so the ping times out. Now I issue the same ping command to send another 4096 byte ICMP request. This time, an ARP entry for sax exists on harpsichord, so no ARP packets are sent. This time, everything looks normal: 21:41:19.647643 0:60:97:6c:6f:b0 10:0:5a:fa:4e:9e 0800 1514: 128.59.68.72 > 128.59.68.56: icmp: echo request (frag 15424:1480@0+) 21:41:19.648423 0:60:97:6c:6f:b0 10:0:5a:fa:4e:9e 0800 1514: 128.59.68.72 > 128.59.68.56: (frag 15424:1480@1480+) 21:41:19.649053 0:60:97:6c:6f:b0 10:0:5a:fa:4e:9e 0800 1178: 128.59.68.72 > 128.59.68.56: (frag 15424:1144@2960) 21:41:19.652758 10:0:5a:fa:4e:9e 0:60:97:6c:6f:b0 0800 1514: 128.59.68.56 > 128.59.68.72: icmp: echo reply (frag 12732:1480@0+) 21:41:19.654060 10:0:5a:fa:4e:9e 0:60:97:6c:6f:b0 0800 1514: 128.59.68.56 > 128.59.68.72: (frag 12732:1480@1480+) 21:41:19.655099 10:0:5a:fa:4e:9e 0:60:97:6c:6f:b0 0800 1178: 128.59.68.56 > 128.59.68.72: (frag 12732:1144@2960) I originally observed this behavior on a 3.0CAM snapshot with my not quite complete (but largely functional) RealTek driver, however it appears to manifest itself on 2.2.x too. I'm at a loss to explain what's going on here, but something's clearly wrong. For a while I was convinced that my driver was at fault, but after adding some debug code I realized that the transmit start routine was only being called with one fragment, so the other fragments weren't even making it to the device driver stage. This is further evidenced by the fact that I can reproduce the problem on 2.2.6 with a totally different driver. I have no idea if this behavior goes all the way back to 2.1.x. Note that larger ICMP datagram sizes will also trigger the behavior: on FreeBSD 3.0, I was able to specify a size of 8100 bytes without ping complaining, but again only the last fragment of the first datagram gets transmitted (subsequent datagrams send after the ARP request/reply exchange are send properly). If anybody has any insights on this, I'd love to hear them. I really don't want to wade through TCP/IP Illustrated Vol.II trying to track this down. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Mon Sep 21 22:32:24 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id WAA21949 for freebsd-net-outgoing; Mon, 21 Sep 1998 22:32:24 -0700 (PDT) (envelope-from owner-freebsd-net@FreeBSD.ORG) Received: from skynet.ctr.columbia.edu (skynet.ctr.columbia.edu [128.59.64.70]) by hub.freebsd.org (8.8.8/8.8.8) with SMTP id WAA21937; Mon, 21 Sep 1998 22:32:10 -0700 (PDT) (envelope-from wpaul@skynet.ctr.columbia.edu) Received: (from wpaul@localhost) by skynet.ctr.columbia.edu (8.6.12/8.6.9) id BAA25338; Tue, 22 Sep 1998 01:37:05 -0400 From: Bill Paul Message-Id: <199809220537.BAA25338@skynet.ctr.columbia.edu> Subject: Nebbermind To: current@FreeBSD.ORG, freebsd-net@FreeBSD.ORG, wollman@FreeBSD.ORG Date: Tue, 22 Sep 1998 01:37:03 -0400 (EDT) X-Mailer: ELM [version 2.4 PL24] Content-Type: text Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Duh...

See Stevens Vol. II on ARP, and the definition of struct llinfo_arp and arpresolve() in netinet/if_ether.c. Only the last packet is held, which in your case is the last fragment.

There is a search engine at www.freebsd.org/ports/ and everyone should have installed the ports collection (if you didn't, then you can cvsup it) In any case, a quick search of the aforementioned site reveals that you can install ucd-snmp at /usr/ports/net/ucd-snmp, so a simple (cd /usr/ports/net/ucd-snmp && make all install) should be all someone needs to install it.

The problem occurs after a short network outage, when the server side of a connection is still in state ESTABLISHED, but the client has timed out while transmitting, and closed its end of the connection. When network connectivity returns, an attempt to set up the same connection (same client port) will repeatedly time out. The code used to handle out-of-sequence ACKs when in state SYN-SENT is: /* * If we have a cached CCsent for the remote host, * hence we haven't just crashed and restarted, * do not send a RST. This may be a retransmission * from the other side after our earlier ACK was lost. * Our new SYN, when it arrives, will serve as the * needed ACK. */ if (taop->tao_ccsent != 0) goto drop; else goto dropwithreset; When the client tries to re-connect, the server responds with an out-of-sequence ACK as expected. However I think the above code is dropping the ACK without sending a RST because the client has a cached rfc1644 CCsent from the server machine. Without a RST, the server end of the connection never leaves state ESTABLISHED so retransmissions of the SYN do no good, and the client connection times out. I presume that changing the above code to send a RST always will fix the problem, but at the expense of a few extra RST packets in other situations. Or maybe there's a better condition that could be tested? I couldn't find any information in rfc1644 about handling ACKs in SYN-SENT, so presumably the current behaviour isn't standard. Turning off rfc1644 extensions would almost certainly work around the problem of course.

I am just having trouble figuring out a couple of things: 1.) How to specify a range of ip's to scan from the command line. For now I have genreated a list in a file of all ip's I am wanting to scan and using the -i option, but am curious if this can be done direct from the command line.? 2.) I am a bit fuzzy as well on how to check for every prot number say from 21 to 30000. I have tried the -b 21 -e 30000 but think it may skip some numbers. an example I have a machine that if I try: strobe -b 21 -e 125 xxx.xxx.xxx.125 I get nothing back on port 110. but if i type: strobe -b 110 -e 125 xxx.xxx.xxx.125 then I get feedback from port 110 saying the pop3 is running and ok. I am wanting to check every possible number in a range and I am confused. Can someone help? Thanks! -- http://www.rjent.pair.com FreeBSD, nothing but the BEST! Samba + FreeBSD = Free PDC!

Sorry, I was unclear - I was meaning only adding RED to the lower-priority classes; in other words, just drop some of those, instead of dropping the higher-priority ones. That way, a higher proportion (but not a fixed proportion) of the bandwidth is devoted to the higher-priority ones, _if_ there's a congestion problem. Admittedly, I haven't worked this out with a net simulator, as one should probably do when dealing with such issues. > In any case, RED support is very very very easy to add to dummynet. > To get the idea, the most difficult part is the ipfw code to pass > RED parameters to the kernel! Nice... although given other capabilities that IpFilter has (including ones that I've patched into it, such as making ICMP messages look like they're coming from the supposed destination machine - allowing for what will look to other machines like a bridge, but is actually looking at higher-level information than just the MAC address), it'd be nicer if somebody adapted it and dummynet to work together. -Allen -- Allen Smith easmith@beatrice.rutgers.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Fri Sep 25 23:51:32 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id XAA29311 for freebsd-net-outgoing; Fri, 25 Sep 1998 23:51:32 -0700 (PDT) (envelope-from owner-freebsd-net@FreeBSD.ORG) Received: from labinfo.iet.unipi.it (labinfo.iet.unipi.it [131.114.9.5]) by hub.freebsd.org (8.8.8/8.8.8) with SMTP id XAA29304 for ; Fri, 25 Sep 1998 23:51:26 -0700 (PDT) (envelope-from luigi@labinfo.iet.unipi.it) Received: from localhost (luigi@localhost) by labinfo.iet.unipi.it (8.6.5/8.6.5) id HAA13908; Sat, 26 Sep 1998 07:02:57 +0200 From: Luigi Rizzo Message-Id: <199809260502.HAA13908@labinfo.iet.unipi.it> Subject: Re: Packet/traffic shapper ?

All i had to do to support dummynet in ipfw was to add a new return code to the ipfw call so that i could decide to pass accepted packets to a pipe. Once you have done that, you just need to process the return code from (*fr_checkp)(...) in the same exact way it is done for (*ip_fw_chk_ptr)(...) e.g. in ip_input.c (look at the -stable code, since this is not in -current yet). Actually, if we manage to make the kernel interfaces for ipfw and ipfilter the same (they seem to be already 99% compatible) the integration will come for free. So essentially, can you look at how hard would it be to add support for multiple return codes to ipfilter ? Then when the dummynet code will be in -current (hopefully soon) you will be able to use it. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Fri Sep 25 23:52:30 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id XAA29496 for freebsd-net-outgoing; Fri, 25 Sep 1998 23:52:30 -0700 (PDT) (envelope-from owner-freebsd-net@FreeBSD.ORG) Received: from labinfo.iet.unipi.it (labinfo.iet.unipi.it [131.114.9.5]) by hub.freebsd.org (8.8.8/8.8.8) with SMTP id XAA29486 for ; Fri, 25 Sep 1998 23:52:24 -0700 (PDT) (envelope-from luigi@labinfo.iet.unipi.it) Received: from localhost (luigi@localhost) by labinfo.iet.unipi.it (8.6.5/8.6.5) id GAA13849; Sat, 26 Sep 1998 06:35:33 +0200 From: Luigi Rizzo Message-Id: <199809260435.GAA13849@labinfo.iet.unipi.it> Subject: Re: Packet/traffic shapper ?

Your statement seems a bit strange because with RED there are no priorities. In any case, RED support is very very very easy to add to dummynet. To get the idea, the most difficult part is the ipfw code to pass RED parameters to the kernel! I may do it in the future when i have a need for this, if somebody does not beat me. cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
