Iperf works really well: http://dast.nlanr.net/Projects/Iperf/ It will do tcp/udp/multicast; you can pick the rate on the udp side and the client/server architecture lets you measure jitter, out of order packets, loss, etc. So you could load up a fixed rate of udp and then produce your burst using a second copy, etc. to see what happens.

Hey all, Does anyone know of a (preferably opensource) tool that can generate network loads of specific protocols and/or levels (for example, if I wanted to see how much loss I got on a 1 meg spike, over time). I'm hopefully looking for something client/server so I'm not necessarily dependent on reply packets to measure the thoroughput. If anyone has any ideas, I'd love to hear them. Privately if you like, as I realize the potential for misuse of such things. -Dan -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------

At an old transit provider I was at, we had a pig of a time dealing with uRPF. It doesn't like asymmetric routing at all, which is commonplace when you've got customers homed at exchange points for one. I imagine the simplest and most foolproof way around directly connected providers blackholing your traffic is announcing more specific prefixes down the one you're currently favourint, and just the aggregates for same into the second. Good luck if you've only got a bunch of non-contiguous /24s..

It's lower impact, on some cards/chassis/os's, than actual filters and certainly lower management headache to maintain. Keep in mind that sprint has probably a few hundred interfaces on that one router, with a few thousand routers (atleast, again I'm not a sprint person) with similar interface counts... managing acls on a hundred thousand interfaces (non-standard acls) isn't a simple task. > > I'm working through the SprintLink noc/support process but I'm surprised this > hasn't happened to any of their other customers before now. > perhaps other customers just announce their /24 to each provider and don't care about traffic engineering? or they atleat announce the depref'd routes incase of failure? > Am I missing something obvious here? probably not This message and any attachments (the "message") is intended solely for the addressees and is confidential.

OT:ANNOUNCE: MailDroid Spam Fighting MFG/MTA alpha release 0.01
by Geoff White 03 Jun '05

03 Jun '05

The MailDroid iso image is ready for download at http://www.maildroid.org. (at 130 MB, we'll try it for a few days to see if we can afford the traffic) MailDroid is a special "distro" of the popular OpenBSD** operating system that is optimized to provide a secure, spam fighting, virus killing, Mail Filtering Gateway, "right out of the box". System Administrators need only place the MailDroid distro CD into any modern x86 box (Pentium III class or above) and load the system as you would any OpenBSD install except you select the additional maildroid.tgz package. Once all the packages are installed, reboot… and the system will come up swinging! MailDroid comes equipped and configured with: • sendmail 8.13.8 - standard OpenBSD 3.7 release • smtp-vilter 1.1.9- connect several milter back-ends to filter your incoming mail • spamassassin 3.0.2- what more do we need to say? • cyrus-sasl 2.1.20 - SASL2 authentication daemon to use with sendmail • clamav 0.85.1- The open source anti virus milter • squirrelmail 1.4.4– SSL web mail front-end using an internal IMAP server • spamd - The OpenBSD offensive spam deferral daemon • pop3s - TLS based POP access (via stunnel 4.08 ) • OpenBSD firewall based on pf • Chrooted sendmail, apache, clamav, smtp-vilter, named, PHP4.3.10 and more • Secure Web-based management console We put all the work into building, integrating and debugging these tools so you can spend your time, not building packages, but fighting SPAM! While the system comes up, secure and ready to filter, reject, or label spam, we refrain from making any major policy decisions. The system is tunable, in a large-scale sense through the web interface, however you can edit the actual configuration files yourself without worrying that your changes will be lost... all config files changes are placed under version control so if you make a mistake, you can recover easily. MailDroid is Open Source, you are free to modify it, recompile it, use parts of it, even repackage and sell it ( see individual component licenses). If you choose to purchase a CD, you get one year of on-line automatic updates for the host that you decide to register. What this means is that if there are security vulnerabilities, or cool feature improvements available, you don't have to wait, re-compile or re-install, you just have to download the package, install, possibly reboot and your done. Even if you choose not to purchase a CD, you can still have read access to the MailDroid CVS tree, that will contain up to the minute security patches and many feature enhancements. MailDroid is a community effort, it is a effort of System and Network Administrators like yourselves, and we value your suggestions, patches and feature additions, should you choose to contribute them. We are here to make all of our lives a little nicer and to optimize the fun! MailDroid... Now there's a New Hope. Host requirements: • I32 (x86) machine 300MHz (Pentium III) or better (sorry no 64 bit support yet, dual CPU is OK!) • 128MB of memory (512 preferred) • 20 Gigabyte hard drive • CDROM (to load software) • keyboard, VGA monitor (serial support for the console in the BIOS) • 10/100 base-T Ethernet port We can also build custom MailDroids to your specifications and deliver them fully burnt-in, loaded and debugged. From super-fast, 1U, dual processor, bastion servers to small-office, paperback book size, low power units. E-mail us for details and price quotes.

Not much different from many of my networks here, then. > If they're paranoid enough to manually filter my BGP > announcements it's not much more work to manually filter my > source addresses too (nevermind the fact that I already do it > myself, but...) SprintLink has been filtering BGP announcements since we came online with them a few years ago. They'd probably been doing it for some time before then, too. I don't see it as paranoid, to me it's just good practice (if a bit difficult to manage when you're as large as SL is). Stupid questions I must ask: * Did you actually give them all five prefixes when you were setting up your BGP request (your statement is a little vague on that detail)? * Did you request a copy of the BGP filter they're applying to your circuit(s)? Do they look okay? * What do route servers say about your prefixes/AS? EG, does oregon-ix.net see it as hanging off Sprint? * You are announcing off a loopback address, right? > I'm working through the SprintLink noc/support process but > I'm surprised this hasn't happened to any of their other > customers before now. As has already been said, I'm sure it has... You just have to find the engineers who've dealt with those situations before. A lot of their staff is fairly clueful but they're highly departmentalized. BGP team only does their BGP thing, etc. It can be hard to do proper troubleshooting when one team can only go so far before you're forced to hand off and start the process anew. Your best bet is to start with the obvious (get the BGP config and ACLs they're applying for you) and work your way from there. -jfo Jason "Feren" Olsen DeVry, Inc.
