CIDR/Aggregation/Allocation Policies
by Sean Doran 29 Jan '95

29 Jan '95

Does anyone know if anybody from Network Solutions is going to be at NANOG? The CIDR/Aggregation talk looks like it's going to focus a bunch of thought at allocation policies and strategies. (drc, are you going to be there? :) ) Aslo, after a talk with Yakov Rekhter yesterday, I think we certainly can use two hours for the CIDR/Aggregation talk instead of just one (they don't have to be contiguous, and maybe a break between each hour could be useful).

========================================================== The "Expanded Listings" section of this NWG report has been retired since it is sorted by countries and network organization addresses. The replacement configuration generation system is based on the Internet Routing Registry (briefly called the "Global Routing Registry"). See the file ftp.ra.net:pub/radb/OVERVIEW for more information. The remainder of this report will also be retired shortly. ========================================================== The following Midlevel/Regional peering sessions have also been added: AS 1325 - ANS Cleveland - DNSS 43 (US) - DNSS 43 Peer: 192.103.64.3 - ANS - nor-2500-1 Peer: 192.103.64.4 - ANS - nor-2500-2 AS 1693 - (AS 1693) - CNSS 56 Peer: 140.222.56.197 - ANS - cnss61.Washington-DC.t3.ans.net AS 3407 - INTERPATH-NC - ENSS 136 Peer: 192.41.177.160 - Interpath - mae-connect.interpath.net AS690 CIDR Squeezings Report: 9845 Nets, 169 ASs, 2654 Aggregates ------------------------------------------------------------------ 9845 (85%) of the ever-announced more-specific routes within aggregates have been withdrawn. 163 of those were withdrawn within the last week. 396 the week before that. 233 the week before that. 169 ASs have registered aggregates in the PRDB. 148 of those are announcing aggregates. 80 have withdrawn at least one more specific route. 2654 Aggregates are configured. 1910 of these were Top-Level Aggregates (not nested in another aggregate). 1467 of these are being announced to AS690. 1031 of those have at least one subnet configured (the other 436 may be saving the Internet future subnet announcements). 855 have stopped announcing at least one configured more specific route. 832 have stopped announcing half of their configured more specific routes. 775 have stopped announcing most (80%) of their more specific routes. See merit.edu:pub/nsfnet/cidr/cidr_savings for more detail. ----------------------------------------------------------- ========================================================== The configuration reports which reflect today's update will be available for anonymous ftp on nic.merit.edu by 08:00 EST : configuration reports -- nic.merit.edu:nsfnet/announced.networks: as-as.now as-gw.now ans_core.now country.now net-comp.now nets.doc nets.non-classful nets.tag.now nets.unl.now NSS routing software configuration files -- nic.merit.edu:nsfnet/backbone.configuration: gated.nss<NSS number>.t3p Information is also avaiable through the PRDB whois server. Type "whois -h prdb.merit.edu help" for details. -------------------------------------------------------------------------- PRDB CHANGES: (Updated January 19, 1994) As of 1/19/95, ACKs and NAKs will no loger be required (or even read) in the processing of NACRs. In early 1995, as part of the transition to the new Internet Routing Registry (IRR), the Policy Routing Database (PRDB) will be retired. Many of the functions of the PRDB (including generation of router configurations for NSFNET) will be produced based on data from the Global Routing Registry. This change to the NSFNET Backbone service will involve the following changes: - The method for submitting new nets to be routed over AS690 will change. Instead of submitting a NACR to nsfnet-admin(a)merit.edu, you will need to submit a "route template" to auto-dbm(a)ra.net . - Additions and entries to the new registry will be made by the Home AS which creates the route for each net, rather than being submitted by a AS690 peer AS. - Most of the PRDB reports (listed above) will no longer be produced. Equivalent information for most of these reports is available from the global Routing Registry. These are major changes to the system. These changes are being made in order to migrate NSFNET customers and the global user community to a global Internet Routing Registry system, which will be more capable of supporting user needs after the termination of the NSFNET Backbone services in April 1995.

CERT Advisory CA-95:02.binmail.vulnerabilities
by cert-advisory＠cert.org 26 Jan '95

26 Jan '95

============================================================================= CA-95:02 CERT Advisory January 26, 1995 Vulnerabilities in /bin/mail ----------------------------------------------------------------------------- This advisory supersedes CA-91:01a SunOS Mail Vulnerability and CA-91:13 Ultrix Mail Vulnerability. There are vulnerabilities in some versions of /bin/mail. Section III below provides vendor-specific information and an alternative to /bin/mail. As we receive additional information relating to this advisory, we will place it, along with any clarifications, in a CA-95:02.README file. CERT advisories and their associated README files are available by anonymous FTP from info.cert.org. We encourage you to check the README files regularly for updates on advisories that relate to your site. ----------------------------------------------------------------------------- I. Description Some versions of /bin/mail based on BSD 4.3 UNIX are vulnerable because of timing windows in the way /bin/mail uses publicly writable directories. II. Impact Local users (users that have an account on the system) can create or modify root-owned files on the system and can thereby gain unauthorized root access. III. Solutions Either install a patch from your vendor or replace /bin/mail with mail.local. A. Obtain the appropriate patch from your vendor and install it according to the instructions included with the patch. Below is a summary of the vendors listed in the current version of the CA-95:02.README file, and the status they have provided. More complete information, including how to obtain patches, is provided in Appendix A of this advisory and reproduced in the README file associated with this advisory. We will update the README file as we receive more information from vendors. If your vendor's name is not on this list, please contact the vendor directly. Vendor or Source Status ---------------- ------------ Apple Computer, Inc. not vulnerable Berkeley SW Design, Inc. (BSDI) not vulnerable Data General Corp. not vulnerable Digital Equipment Corp. vulnerable, patches available FreeBSD not vulnerable Harris not vulnerable IBM not vulnerable NetBSD not vulnerable NeXT, Inc. not vulnerable Pyramid not vulnerable The Santa Cruz Operation (SCO) see note in Appendix A Solbourne (Grumman) vulnerable - contact vendor Sun Microsystems, Inc. SunOS 4.x vulnerable, patches available, patch revisions coming soon Solaris 2.x not vulnerable B. Replace /bin/mail with mail.local. If you cannot obtain a vendor-supplied replacement for /bin/mail, the CERT Coordination Center recommends using mail.local as a replacement for /bin/mail. Although the current version of mail.local is not a perfect solution, it addresses the vulnerabilities currently being exploited in /bin/mail. As improvements to mail.local become available, we will note them in the README file associated with this advisory. The current version of mail.local has been tested on SunOS 4.1 and Ultrix 4.X systems. Mail.local.c for BSD 4.3 systems, along with a README file containing installation instructions, can be found on the anonymous FTP servers listed below. In addition, Appendix B of this advisory contains the the README file and Appendix C contains mail.local.c.

Appendix A: Vendor Information Current as of January 26, 1995 See CA-95.02.README for updated information Below is information we have received from vendors who have patches available or upcoming for the vulnerabilities described in this advisory, as well as vendors who have confirmed that their products are not vulnerable. If your vendor's name is not in one of these lists, contact the vendor directly for information on whether their version of sendmail is vulnerable and, if so, the status of patches to address the vulnerabilities. NOT VULNERABLE -------------- The following vendors have reported that their products are NOT vulnerable. Apple Computer, Inc. Berkeley SW Design, Inc. (BSDI) Data General Corp. Harris IBM NeXT, Inc. Pyramid The Santa Cruz Operation (SCO) - not vulnerable, but see note below Sun Microsystems, Inc. - Solaris 2.x (SunOS 4.x is vulnerable; see below) In addition, we have reports that the following products are NOT vulnerable. FreeBSD NetBSD VULNERABLE ---------- We have reports that the following vendors' products ARE vulnerable. Patch information is provided below. ----------------------------- Digital Equipment Corporation Vulnerable: DEC OSF/1 versions 1.2, 1.3, and 2.0 DEC ULTRIX versions 4.3, 4.3A, and 4.4 Obtain and install the appropriate patch according to the instructions included with the patch. The patch that corrects the /bin/mail problem in each case is part of a comprehensive Security Enhanced Kit that addresses other problems as well. This kit has been available since May 17, 1994. It is described in DEC security advisory #0505 and in CERT bulletin VB-94:02. 1. DEC OSF/1 Upgrade/install OSF/1 to a minimum of V2.0 and install Security Enhanced Kit CSCPAT_4061 v1.0. 2. DEC ULTRIX Upgrade/install ULTRIX to a minimum of V4.4 and install Security Enhanced Kit CSCPAT_4060 v1.0. Both kits listed above are available from Digital Equipment Corporation by contacting your normal Digital support channel or by request via DSNlink for electronic transfer. ----------------------------- The Santa Cruz Operation (SCO) SCO's version of /bin/mail is not vulnerable to the problems mentioned in this advisory. SCO's /bin/mail is not setuid-root. However, SCO's /bin/mail has other security-related issues that are fixed by SCO's Support Level Supplement (SLS) uod392a.

Please contact them for further information. ftp: ftp.nts.gssc.com phone: 1-800-447-2861 e-mail: support(a)nts.gssc.com ----------------------------- Sun Microsystems, Inc. Current patches are listed below, but they are being revised. SunOS Patch MD5 Checksum ------ ----- ------------ 4.1.3 100224-13.tar.Z 90a507017a1a40c4622b3f1f00ce5d2d 4.1.3UI 101436-08.tar.Z 0e64560edc61eb4b3da81a932e8b11e1 The patches can be obtained from local Sun Answer Centers and through anonymous FTP from ftp.uu.net in the /systems/sun/sun-dist directory. In Europe, the patches are available from mcsun.eu.net in the /sun/fixes directory. Appendix B: README File for mail.local.c /bin/mail is a setuid root program with several security vulnerabilities. If you cannot obtain a vendor-supplied replacement for /bin/mail, the CERT Coordination Center suggests using mail.local as a replacement for /bin/mail. In the early days of UNIX, /bin/mail was used to read and to send e-mail. Over the years, many users have switched to e-mail programs with better user interfaces and more features. On BSD 4.3 based UNIX systems using sendmail, /bin/mail is still being used as the local delivery agent. These systems could be at risk. Systems based on UNIX system III or system IV are not vulnerable. mail.local is a replacement for the /bin/mail program. It is only a delivery agent for sendmail and does not have a user interface. It is distributed as a C source file. For operating systems based on BSD 4.3, mail.local.c from a BSD 4.4 distribution will not compile. The version of mail.local.c in this directory was ported to BSD 4.3 by Eric Allman. It should compile and operate on most BSD 4.3 systems. It has been tested on SunOS 4.1.x and Ultrix 4.x systems. To install mail.local, edit the source file to set the _PATH_MAILDIR to the directory where users' spooled mail files are located. The default is "/var/spool/mail". SunOS % cc -Bstatic -O -o mail.local mail.local.c Ultrix % cc -O -o mail.local mail.local.c -Dultrix As root: # mv mail.local $INSTALL_DIR Substitute $INSTALL_DIR for the full pathname of the directory where mail.local will be installed. # chown root $INSTALL_DIR/mail.local # chmod 4711 $INSTALL_DIR/mail.local Edit the sendmail.cf file (in /etc or /usr/lib) search for Mlocal. On that line, replace /bin/mail with $INSTALL_DIR/mail.local. Restart the sendmail process. For versions of sendmail using frozen configuration files, it is important to refreeze the configuration file before restarting the sendmail process. Test the e-mail system. When you are satisfied that everything is working, disable the setuid root bit on the /bin/mail program. # chmod 0711 /bin/mail OR # chmod 0711 /usr/bin/mail **************************************************************************** * The CERT Coordination Center will not formally review, evaluate, or * * endorse the program described. The decision to use the program * * described is the responsibility of each user or organization and we * * encourage each organization to thoroughly evaluate this program * * before installation or use. * **************************************************************************** Appendix C: mail.local.c /*- * Copyright (c) 1990, 1993, 1994 * The Regents of the University of California.

Sean, Thanks for bringing this up (agneda topics). }-- Security problems operators can fix } [or, how to let your customers be used to break into } interesting places] } (route announcement filtering vs. routing attacks } outbound packet filters on CPE routers vs. spoofing } attacks like the ones CERT announced recently) }This could go fairly quickly. Is there anyone who will volunteer to lead this discussion? } -- Routing flaps considered harmful Is there a volunteer to lead this topic? | 2) technical presentation on what is a route server Yakov Rekhter has volunteered to give a technical presentation on the RA's Route Server implementation. } Is this going to be from an RA/RS perspective? If } so, some talk about converting extremely complicated } policy now embedded in border Ciscos to something } that can be put into the RA/RSes would be neato. } (Also what that policy ought to be in very broad } terms ("NAP/MAE technical etiquette") might be } useful as a short side-line talk.)

There is room on the agenda for a presentation on the utility of the route server concept or implementation (RA since noone has volunteered infor on another implmentation). } 5) end-to-end problem resolution - is it possible? I have approached two candidates to lead this discussion - neither have confirmed yet. Other agenda topics are welcome...we should be distributing an agenda sometime this weekend. --Elise

Hm, I would think most would want that behaviour configured in the current way... because it makes network debugging so much easier. Based on many years of beating my head against various network reliability problems, I would say that it's better to have the route go away and let the user know about it than to throw data into the bit bucket. Maybe we could compromise on an option to leave the route there when the circuit goes down, for those network managers who want to receive calls from users saying "My data went into the bit bucket" and then spend some time to figure out that it's because the circuit went down. -- Walt -------

>I would say that it's better to have the route go away and let the user >know about it than to throw data into the bit bucket. Static routes shouldn't go away. It was a cheap shot to help people who can't configure dynamic routing properly. >Maybe we could compromise on an option to leave the route there when the >circuit goes down, It has to be default to take any effect on global routing flap. Non-default options aren't used by those without a clue; and it is precisely netadmins whith no clue whose networks do most harm to the Internet. >for those network managers who want to receive calls >from users saying "My data went into the bit bucket" and then spend some >time to figure out that it's because the circuit went down. Those "managers" got to fix their routing, ok? --vadim

If it a new religion, will you nominate me for the Prophet? :-) Another thing we really need from router manufacturers is _persistent_ static routes by default. The current behaviour of one rather popular brand of routers (name witheld to protect the guilty) is to remove routes if the associated circuit goes down. We need to change it to have packets to go to the bit bucket instead, and make the old behaviour be configurable with an explicit knob. --vadim

| >Routing flaps considered harmful... | A while ago Curtis proposed a scheme for holddowns that | has a property that a holddown time associated with | a route increases with the frequency of this route | flapping -- so that frequently flapping routes getting | progressively long timeouts. This is a good idea, if a bit of a gross and ugly hack at one aspect of the problem (frequent flaps of one specific set of prefixes). There are also ways of helping out right now that aren't dependent on implementation changes to router software and are better general fixes for the sheer number of flaps, imho. Part of what needs doing is a decision about what should give a host unreachable/network unreachable message. Right now it tends to be a box very close to the originator; I would tend to argue that this is no longer necessarily a good idea, and that in the case of statically-routed single-homed internets a box as close as possible to the destination could do that job just as well (with side effects like fewer globally-visible route-flaps). This dovetails into the new religion that doing BGP or other dynamic routing with singly-homed customers is a bad idea, even for policy or political reasons. If it's *really* necessary to do this (people argue that, among other reasons, this is something that should be done so that the CIX router can distinguish CIX member routes from non-CIX-member routes belonging to non-CIX-member resellers), it probably would be better to route them statically and advertise a lie saying that the routes originated in e.g. BGP or EGP with AS XXXX.

We are in the process of putting together the agenda for the Feb 9-10 meeting of NANOG. Does anyone have any topics which they would like to see on the agenda? Some suggestions that we have had are: 1) status of the transition to the new NSF Architecture 2) technical presentation on what is a route server 3) discussion on cooperatively rationalizing MBONE routing 4) IPv6 transition 5) end-to-end problem resolution - is it possible? 6) RADB - how to use it 7) ATM testbed results Please send those cards and letters soon - otherwise we'll just have to make up something. --Elise
