Hence, any test of this nature is going to test the application implementation as much as the nature of the protocols, per se. Both ttcp and netperf have the ability to use either TCP or UDP. The behavior of TCP is, I think well understood. OTOH, I don't think you should discount the use of ttcp's/netperf's UDP method. Rather consider the receiver's measurement as an upper bound of what a particular retransmitting UDP implementation can acheive. As has been pointed out, the UDP_RR method for netperf looks interesting, but the documentation is scant. Use the source, Luke. -- Clark K.

I tried protocol 1 in openssh and protocol 2 in openssh and Ylonen's SSH 2.3.0 via PSTN 56K line. With protocol 1 interactive delays are reasonable. With protocol 2, in both openssh and Ylonen's ssh, delays are unreasonable annoying. When going to localhost, all is OK. My impression is those delays are similar to ones in case when TCP_NODELAY was not turned on. Openssh client is standard from -current date=2001.05.12.00.00.00 (`SSH-1.99-OpenSSH_2.9 green@FreeBSD.org 20010503').

My doubt is whether this message will be generated only for addresses other than link local & multicast or it will be generated for all the addresses. It depends on the kernel implementation, but, in any case, all routes that users (applications) manually install to the kernel will be announced through the routing socket, even if the routes are link-local or multicast ones. And, in my understanding, on FreeBSD 4.3 (and prior versions), other routes will basically not be announced. In particular, routes automatically installed via RA messages will not be announce through the routing socket. JINMEI, Tatuya Communication Platform Lab.

And even when I add a route to this network throw any of the interfaces it still returns ENETUNREACH message. Then I thought that I can fix that with -ifp modifer of route command but - no luck. After many tryes I found a way to set this route but I don't think it's the right way it should be done. Ok, now you have an interface with IP 2.2.2.2 but your gateway is 1.1.1.1 . First you should add a default route from your interface's network or even his own IP 2.2.2.2 , then you should change this route gateway to point to real gateway 1.1.1.1 and you should have a route to this host or his network 1.1.1.1/??. Here is same but displayed with route command: 1. route add default 2.2.2.2 2. route add 1.1.1.1 -iface xl0 arp -s 1.1.1.1 lladdr_of_1.1.1.1 or route add -net 1.1.1.1/24 -iface xl0 3. route change default 1.1.1.1 4. optionaly : route change default -ifp xl0 That did it but why can't I do it with this command: route add default 1.1.1.1 -ifp xl0 I look in sys/net/rtsock.c and sys/net/route.c and saw that rtrequest() can't add a route to host throw interface but route_output() function in rtsock.c could change it that way ?!? I've changed these tow functions and now "route add default host -ifp ifname" works but you still need a route to the gateway. I think that if there is set ifp or ifa (end this is set if there is a route at all :)) the kernel should try to arpresolve gateway's lladdr throw that interface if it can't find a route to it.

The IP address of the gateway is not from network that the computer is. But there is a route throu interface to it and the kernel still refuses to use that gateway with error ENETUNREACH. And I wrote a patch which allows kernel to set that route. It's kinda unfinished still but it works. Even now (without the patch) you can set this route but it's not straight forward and I don't think that's the right way to be done. Regards.

Yes, I know, freebsd kernel have now supporting for VLAN's (pseudo-device vlan), but it have number of disadvantages: - fixed number of vlan interfaces - vlanX pseudo-interfaces don't support netgraph'ing, so I can't bridge two VLANs using ng_bridge - fixed vlanX interfaces numbering, so if I want use VLANs from 320 to 340, so I can use interfaces vlan0 - vlan20, but if I use VLANs with ID's 1-20 it will be confusing. If I want interface names vlan320-vlan340, I need to specify in kernel 340 vlan interfaces. But contrary in netgraph scheme I can name interface connected to 802dotQ node hook vlan320 as, for example, vlan340 without any problem. -- TSB Russian Express, Moscow Vladimir B.

The following program binds *:1000 to a socket, and then tries to bind 200.47.36.254:1000 to another socket, the error i gets is "Address already in use". Why? I am not asking for a "you're not allowed to do that", I know. I don't ask for a "why are you trying to do that?", I amn't trying. But I need to know why that's not permited. I know vaguely but i need a more sound explanation. A pointer to a mailing list/usenet archive where the subject was discussed in the past would be great. Just another time, i am asking for the theory about why that shouldn't be allowed. Not the fact that it's not allowed.

Why? *:1000 includes 200.47.36.254:1000 by definition of bind(2). Binding two sockets to one address (200.47.36.254:1000 in your case) cannot be allowed because it is unclear which of the two sockets should recieve packets destined to 200.47.36.254:1000. There may be other reasons. Alex.

That is just broken IMHO. You will also need to disable any e/ingress-filtering that may be on the gateway. The right thing to do would be to assign an address on that net to your interface which will allow you to point your default gateway at an address on that net. -- Hroi Sigurdsson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Wed May 30 16:57:15 2001 Delivered-To: freebsd-net@freebsd.org Received: from whizzo.transsys.com (whizzo.TransSys.COM [144.202.42.10]) by hub.freebsd.org (Postfix) with ESMTP id AAE5A37B422; Wed, 30 May 2001 16:57:09 -0700 (PDT) (envelope-from louie@whizzo.transsys.com) Received: (from louie@localhost) by whizzo.transsys.com (8.11.3/8.11.3) id f4UNv8k14534; Wed, 30 May 2001 19:57:09 -0400 (EDT) (envelope-from louie) Date: Wed, 30 May 2001 19:57:09 -0400 (EDT) From: Louis Mamakos Message-Id: <200105302357.f4UNv8k14534@whizzo.transsys.com> To: FreeBSD-gnats-submit@freebsd.org Subject: ipf packet munging bug using "to" option in rule Reply-To: louie@whizzo.transsys.com Cc: freebsd-net@freebsd.org, darrenr@freebsd.org X-send-pr-version: 3.113 X-GNATS-Notify: Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org >Submitter-Id: current-users >Originator: Louis Mamakos >Organization: dept of serendipity scheduling and managment >Confidential: no >Synopsis: ipf packet munging bug using "to" option in rule >Severity: serious >Priority: medium >Category: kern >Class: sw-bug >Release: FreeBSD 4.3-STABLE i386 >Environment: System: FreeBSD whizzo.transsys.com 4.3-STABLE FreeBSD 4.3-STABLE #18: Sat May 12 20:38:19 EDT 2001 louie@whizzo.transsys.com:/usr/src/sys/compile/SAYSHELL i386 >Description: I'm using ipf on a machine to perform some stupid packet tricks, including the dubious operation of fowarding traffic out an alternative network interface based on the source address of the packet. The reasons why are beyond the scope of this PR. I have a rule that looks something like this: pass out quick on de0 from any to any head 11 block out quick on de0 to tun0 from 144.202.0.0/16 to !144.202.0.0/16 group 11 ... The intent is that when packets from 144.202.0.0/16 arrive on this host, that they get forcebly shoved out the tun0 network interface, rather than taking the expect forwarding path via the de0 interface. This works MOST OF THE TIME. However, sending packets larger than a certain size results in the packet being mangled. It turns out this happens when the packet is large enough that it can no longer be contained within a single mbuf, and there's an mbuf cluster attached. There is code in sys/netinet/ip_fil.c:ipfr_fastroute() which does something like this (paraphrased):n ip->ip_len = htons(ip->ip_len); ip->ip_off = htons(ip->ip_off); if (!ip->ip_sum) ip->ip_sum = in_cksum(m, hlen); error = (*ifp->if_output)(ifp, m, (struct sockaddr *)dst, ro->ro_rt); if (i) { ip->ip_id = ntohs(ip->ip_id); ip->ip_len = ntohs(ip->ip_len); ip->ip_off = ntohs(ip->ip_off); } The problem is that if the outbound network interface saves a pointer to the cluster, it will pick up up the version of the packet after it's been modified by the ntohs() calls after the if_output routine is called. In my case, this happens on a tunnel interface but other network interfaces which can DMA directly from the mbufs rather than copying the data will suffer from the same problem. >How-To-Repeat: as described, sorta.. >Fix: I did a brutal hack in ipfr_fastroute() to make a copy of the mbuf if it's not M_WRITABLE(), and then arranged for the if (i) case in the code above to never get run to corrupt the data in the mbuf. I don't understand the global structure of the ipf code well enough to know if that's a "proper" way to solve the problem or not. After applying the workaround, traffic is now working where previously I was getting nasty checksum errors and the like due to some of the fields being byte-swapped. I would imagine that big-endian systems and those with network interfaces that require the transmit data to be copied wouldn't have seen this problem previously. --- /sys/netinet/ip_fil.c Sun Feb 25 10:53:34 2001 +++ /tmp/ip_fil.c Wed May 30 19:50:45 2001 @@ -1284,6 +1284,32 @@ struct route iproute; frentry_t *fr; +#ifdef __FreeBSD__ + /* + * HOT FIX/KLUDGE: + * + * If the mbuf we're about to send is not writable (because of + * a cluster reference, for example) we'll need to make a copy + * of it since this routine modifies the contents. + * + * If you have non-crappy network hardware that can transmit data + * from the mbuf, rather than making a copy, this is gonna be a + * problem. + */ + + if (M_WRITABLE(m) == 0) { + if ((m0 = m_dup(m, M_DONTWAIT)) != 0) { + m_freem(m); + m = m0; + } else { + error = ENOBUFS; + m_freem(m); + ipl_frouteok[1]++; + return 0; + } + } +#endif + hlen = fin->fin_hlen; ip = mtod(m0, struct ip *); @@ -1379,12 +1405,17 @@ # if BSD >= 199306 int i = 0; +#ifdef __FreeBSD__ + /* HOT FIX: we've already made a copy of the mbuf + above, so we won't need to restore it here. */ +#else /* __FreeBSD__ */ # ifdef MCLISREFERENCED if ((m->m_flags & M_EXT) && MCLISREFERENCED(m)) # else if (m->m_flags & M_EXT) # endif i = 1; +#endif /* __FreeBSD__ */ # endif # ifndef sparc # ifndef __FreeBSD__ @@ -1399,7 +1430,9 @@ error = (*ifp->if_output)(ifp, m, (struct sockaddr *)dst, ro->ro_rt); if (i) { +# ifndef __FreeBSD__ ip->ip_id = ntohs(ip->ip_id); +# endif ip->ip_len = ntohs(ip->ip_len); ip->ip_off = ntohs(ip->ip_off); } To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Wed May 30 21:46:42 2001 Delivered-To: freebsd-net@freebsd.org Received: from imo-d09.mx.aol.com (imo-d09.mx.aol.com [205.188.157.41]) by hub.freebsd.org (Postfix) with ESMTP id 9C3FF37B422 for ; Wed, 30 May 2001 21:46:37 -0700 (PDT) (envelope-from raviprasad20@netscape.net) Received: from raviprasad20@netscape.net by imo-d09.mx.aol.com (mail_out_v30.22.) id n.2c.170c5c1 (16230) for ; Thu, 31 May 2001 00:46:34 -0400 (EDT) Received: from netscape.com (aimmail09.aim.aol.com [205.188.144.201]) by air-in02.mx.aol.com (v77_r1.37) with ESMTP; Thu, 31 May 2001 00:46:33 -0400 Date: Thu, 31 May 2001 00:46:33 -0400 From: raviprasad20@netscape.net To: freebsd-net@freebsd.org Subject: rtmsg_input function of rtadvd daemon Mime-Version: 1.0 Message-ID: <11D7AE68.34A48F69.9513E96F@netscape.net> X-Mailer: Franklin Webmailer 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hi, My understanding of this function is like this.

I was originally looking at vpnd, but it appears that everything I need is available in the 4.3 kernel via IPsec. The two offices are running Windows (95, 98, & NT4) on the desktop and are connected to the net via DSL. While I will have static external IPs to work with, it's likely that the DSL router is set up in PPP mode with NAT enabled. Assuming DSL router's inside address is 10.0.0.1, would I want to set my gateway's outside IF to 10.0.0.2 and the inside to 10.0.1.1, with all the desktops on the 10.0.1 network? Here's what I'm thinking: < PC net on 10.0.3.0 > | | |---- 10.0.3.1 ----| | FBSD | |---- 10.0.2.2 ----| | | |---- 10.0.2.1 ----| | DSL Router | |---- Inet addr ---| | | (~~~~~~~~~) ( ) ( The Big I ) ( ) (_________) | | |---- Inet addr ---| | DSL Router | |---- 10.0.0.1 ----| | | |---- 10.0.0.2 ----| | FBSD | |---- 10.0.1.1 ----| | | < PC net on 10.0.1.0 > Will this work, or will the DSL router's NAT break IPsec? Also, are there problems with traffic to/from the Internet? Should I NAT that, or just use a 255.255.0.0 mask?

Whenever an entry ages out of your arp table, and if the machines decide to talk again thereafter, an ARP request will be issued to resolve the MAC address which will subsequently be cached in your ARP table and aged out over time. The ARPs apparently aren't making it across.. Something to check, is are both machines using the listening to the same broadcast address? Are you running some kind of broadcast suppression on your LAN, any kind of firewall filtering?

Simple network: - two routers (1 and 2) - host C with IP 192.168.1.3 - host S with IP 192.168.2.1 All machines are FreeBSD 4.3-STABLE. Router 1 routes pkts between the Internet and 192.168.1.0 Router 2 routes pkts between 192.168.1.0 and 192.168.2.0 +-----+ +-----+ default | | 192.168.1.0 | | 192.168.2.0 -----------| 1 |--------+--------| 2 |--------+-------- more hosts | | | | | | +-----+ | +-----+ | | | +-----+ +-----+ | | | | 192.168.1.3 | C | | S | 192.168.2.1 | | | | +-----+ +-----+ Relevant parts of netstat -rn on C during normal operation: ------------------------------------------------------------- Destination Gateway Flags Netif Expire default 192.168.1.1 UGSc fxp0 127.0.0.1 127.0.0.1 UH lo0 192.168.1 link#1 UC fxp0 => 192.168.1.1 0:e0:18:90:91:bb UHLW fxp0 1182 192.168.1.2 0:e0:18:90:94:c8 UHLW fxp0 1058 192.168.1.3 0:e0:18:90:45:dc UHLW lo0 192.168.1.255 ff:ff:ff:ff:ff:ff UHLWb fxp0 192.168.2 192.168.1.2 UGc fxp0 The syslogd on host C is configured to log messages to syslogd running on host S. This works perfectly, all messages appear on host S. Now we delete the route to net 192.168.2.0 on host C. When syslogd wants to send another message to S, the kernel uses the default route which is obvious because the route to net 192.168.2.0 is gone. We can see the packets going into router 1. This is OK as well. Now we bring back the route to net 192.168.2.0 again on host C exactly as it was before. We can verify this with netstat -rn on C. We can also ping host S or telnet to it or do other stuff which all work perfectly. The problem is that each time when syslogd on C wants to send a packet to S, the kernel still uses 1 as router even though it should send them through 2. After HUPing or restarting syslogd on C (which means that the UDP socket is closed and opened again) things are back to normal. Is this a know "feature"? It seems that as long as the socket can send the packets somewhere it doesn't bother if there is a better route to the destination until it is closed and opened again.

I'm trying to use pcanywhere to get to an external host, and while I see a lot of info about natd, I am using ppp (yes its painful) with nat. Here's the thing:I don't care about running a HOST behind NAT, just remote (work-from-home), and for some reason I can connect to hosts at my ISP, and if I have a pcanywhere connection open to hosts at my isp, I can also connect to my job (which is not my isp), but unless I have the pcanywhere connection open to my isp, I can't connect to any host outside the local net. To my knowledge (and I've examined both nets carefully) there's no firewalls in place, I should not need to make any allowances on my nat firewall because I'm simply running a remote, not a host. Can anyone offer any advice? -Dan Mahoney -- "SOY BOMB!" -The Chest of the nameless streaker of the 1998 Grammy Awards' Bob Dylan Performance. --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Web: http://prime.gushi.org finger danm@prime.gushi.org for pgp public key and tel# --------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Sat Jun 2 13:15:37 2001 Delivered-To: freebsd-net@freebsd.org Received: from InterJet.dellroad.org (adsl-63-194-81-26.dsl.snfc21.pacbell.net [63.194.81.26]) by hub.freebsd.org (Postfix) with ESMTP id EC38637B423 for ; Sat, 2 Jun 2001 13:15:33 -0700 (PDT) (envelope-from archie@dellroad.org) Received: from arch20m.dellroad.org (arch20m.dellroad.org [10.1.1.20]) by InterJet.dellroad.org (8.9.1a/8.9.1) with ESMTP id NAA21015; Sat, 2 Jun 2001 13:03:34 -0700 (PDT) Received: (from archie@localhost) by arch20m.dellroad.org (8.11.3/8.11.3) id f52K3Ho51512; Sat, 2 Jun 2001 13:03:17 -0700 (PDT) (envelope-from archie) From: Archie Cobbs Message-Id: <200106022003.f52K3Ho51512@arch20m.dellroad.org> Subject: Re: mpdnetgraph connection refused In-Reply-To: "from Peter Brezny at May 31, 2001 02:21:55 pm" To: Peter Brezny Date: Sat, 2 Jun 2001 13:03:17 -0700 (PDT) Cc: freebsd-net@FreeBSD.ORG X-Mailer: ELM [version 2.4ME+ PL82 (25)] MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Peter Brezny writes: > I'm having difficulty with some ms PPTP connections over dsl connections. > > The mpd server works fine for some clients, but not all.
