CSU/DSU selection
by Vince Fuller 20 Feb '92

20 Feb '92

We at BARRNet are considering re-evaluating the T1 CSU/DSUs that we use in an effort to find a more cost-effective solution to connecting small sites which want T1 connectivity (we currently use Cylinks, which might be thought of as the "cadillac" of CSU/DSUs - many features, kinda pricey...) To this end, I'd appreciate hearing about experience that other networks have had with T1 CSU/DSUs made by various manufacturers. The following evaluation criteria are of particular interest: - Cost per unit (list price, price we can expect to get, discount plans offered, if any) - Does manufacuturer offer multi-unit "nest" (and if so, cost) - Framing options (D4 vs. ESF, etc.) - Line encoding options (AMI vs. B8ZS, etc.) - Maximum effective bandwidth (1344 vs. 1536); if full-T1, what scheme is used to guarentee one's density requirement is met Responses to vaf(a)stanford.edu - I'll summarize if there is interest. --Vince

OSI Survey for Regionals attached to the Internet
by skh 19 Feb '92

19 Feb '92

Below is a survey on OSI usage in the Internet. Could you take a moment and fill out this survey? It may look long, but it should only take a few minutes to fill out. Your answers will help the people working on OSI in the Internet plan our next work. Thank you for your help! Please send it in as soon as possible. We'd like to get all responses back within a week. Thank-you, Susan Hares IETF NOOP chair Survey on OSI in Your Network Purpose for Survey: The IETF Network OSI Operational Working Group wants to find out details on OSI use their is in the Internet. The results of the survey will be published as an FYI document for the Internet. Any people answering the Survey will be sent electronic copies of the FYI document on the results of the survey. As people beginning to use OSI on the Internet, the will be able to refer to this document to find out who supports the ISO CLNP layer across the Internet. Timeframe for Survey: Please return this survey by February 27th, 1992. Results will be published as a paper for the NOOP group by March 7th, 1992. Send responses to skh(a)merit.edu. Introduction to the Survey: Questions 1-6 are for those who route Connection Network Layer Packets (CLNP ISO 8473) or DECNET Phase 5 traffic on their network. Questions 7-8 are for those who do not yet route CLNP or DECNET Phase 5. 1.) Do you support the routing of Connection Network Layer Protocol (CLNP (ISO 8473)) packets on your network? If so, 1.1) What number of routers do you have in your network? How many of these routers pass CLNP packets? 1.2) What router vendors do you use in your network? What router vendors do you use in the routers that are passing CLNP packets? 1.3) What type of intra-domain routing do you do within your network? IS-IS? Cisco IGRP based OSI? static? 1.4) What type of inter-domain routing do you do? Cisco poor-man's Inter-domain routing? static? 1.5) Would you be interested in the new ISO Inter-Domain Routing Protocol (IDRP (ISO CD 10747)) when it becomes available? 1.6) Do you consider the OSI service to be: Production - guaranteed delivery and high level of service, Experimental - guaranteed delivery, but service not at highest level Prototype - A first offerings of CLNP which is limited to a few sites, or Pilot - For demonstrations and Pilot projects only? Please select the category nearest to your service. You may include other comments to further qualify this service level. 1.7) If you are running both IP and CLNP, What do you consider your IP service - Production, Experimental, Prototype, or Pilot? 1.8) What amount of traffic do you pass per day, per week and per month? 2.) Are you now routing DECNET Phase 5 traffic on your system? If you are routing DECNET Phase 5: a.) What type of routers are you using? (manufacturer and model? b.) How many routers do you have? c.) What type of hosts are sending traffic? d.) How many DECNET Phase 5 hosts do you have? 3.) Do you currently attach one or more OSI vendor company to your network? Do any of these companies send OSI traffic across the network? If so, 3.1) How many OSI companies are attached to your network? 3.2) How many of these OSI companies send application data regularly? 3.3) What are the companies attached to your network? 3.4) What applications are these companies using? It would be helpful to list the applications by company if that is possible. 3.5) Would any of these companies be interested in "Pilot" projects to try exchanging OSI applications with those people on the Internet. 4.) Do you support OSI applications at your network site? If so, 4.1) What applications do you support? Do you support: X.500 X.400 FTAM VT Xwindows SQL based applications CMIP (please answer yes or no to each applications) others - please list with company 4.2) For each of the applications you answered yes to above please indicate: a.) equipment the application runs on b.) does it run over CLNP/TP4 stack or TCP/IP stack c.) what vendor supplies the software d.) any comments on how easy it is to use e.) Is your application based on ISODE? If so what version of ISODE? 4.3) Are you a part of a Pilot Project or testing group for this application? 4.4) Would you be willing to be a part of a Pilot Project or testing group for this application? 4.5) Do you have a set of routers or hosts which could form a "test bed" at your site? 4.6) Would you be willing to allow this test bed (either a short term or long term basis) to join with other test beds at other networks to test out new software in the Internet? 4.6) Would you be willing to have a "test bed" at your site if additional funding for this was available? Would you be willing on either a short term or long term basis to allow 5.) Do you have any of the following network tools on your routers? a.) OSI ping (or echo function) b.) OSI traceroute c.) OSI table dump What routers have these functions? How would you rate the User Interface to these network tools - poor, fair, good, or excellent? 6.)

There have been circuit problem for a couple of the circuits into Salt Lake. After a 24 hour test period the problem has been isolated to the tail circuits at Salt Lake. Fortunately a new fiber local loop has been recently installed here. That will probably make a difference. cole(a)cc.utah.edu

CERT Advisory - Internet Intruder Activity
by CERT Advisory 17 Feb '92

17 Feb '92

=========================================================================== CA-92:03 CERT Advisory February 17, 1992 Internet Intruder Activity --------------------------------------------------------------------------- The Computer Emergency Response Team/Coordination Center (CERT/CC) has received information regarding a significant intrusion incident on the Internet. Systems administrators should be aware that many systems on the Internet have been compromised due to this activity. To identify whether your systems have been affected by the activity we recommend that all system administrators check for the signs of intrusion detailed in this advisory. This advisory describes the activities that have been identified as part of this particular incident. This does not address the possibility that systems may have been compromised due to other, unrelated intrusion activity. --------------------------------------------------------------------------- I. Description The intruders gained initial access to a host by discovering a password for a user account on the system. They then attempted to become root on the compromised system. II. Impact Having gained root access on a system, the intruders installed trojan binaries that captured account information for both local and remote systems. They also installed set-uid root shells to be used for easy root access. III. Solution A. Check your systems for signs of intrusion due to this incident. 1. Check the su, ftpd, and ftp binaries (for example, "/bin/su", "/usr/ucb/ftp" and "/usr/etc/in.ftpd" on Sun systems) against copies from distribution media. 2. Check for the presence of any of the following files: "/usr/etc/..." (dot dot dot), "/var/crash/..." (dot dot dot), "/usr/etc/.getwd", "/var/crash/.getwd", or "/usr/kvw/..." (dot dot dot). 3. Check for the presence of "+" in the "/etc/hosts.equiv" file. 4. Check the home directory for each entry in the "/etc/passwd" file for the presence of a ".rhosts" file containing "+ +" (plus space plus). 5. Search the system for the presence of the following set-uid root files: "wtrunc" and ".a". 6. Check for the presence of the set-uid root file "/usr/lib/lpx". B. Take the following steps to secure your systems. 1. Save copies of the identified files to removable media. 2. Replace any modified binaries with copies from distribution media. 3. Remove the "+" entry from the "/etc/hosts.equiv" file and the "+ +" (plus space plus) entry from any ".rhosts" files. 4. Remove any of the set-uid root files that you find, which are mentioned in A5 or A6 above. 5. Change every password on the system. 6. Inspect the files mentioned in A2 above for references to other hosts. --------------------------------------------------------------------------- If you believe that your system has been compromised, contact CERT/CC or your representative in FIRST (Forum of Incident Response and Security Teams). Internet E-mail: cert(a)cert.sei.cmu.edu Telephone: 412-268-7090 (24-hour hotline) CERT/CC personnel answer 7:30 a.m.-6:00 p.m. EST(GMT-5)/EDT(GMT-4), on call for emergencies during other hours. Computer Emergency Response Team/Coordination Center (CERT/CC) Software Engineering Institute Carnegie Mellon University Pittsburgh, PA 15213-3890 Past advisories, information about FIRST representatives, and other information related to computer security are available for anonymous ftp from cert.sei.cmu.edu (192.88.209.5).

T3 backbone stability
by Mark Knopper 13 Feb '92

13 Feb '92

Dave, I have summarized and enclosed below our trouble tickets written over the last 5 days for the T3 network. The only problem that affected more than one peer site was a crash of CNSS40 at Cleveland yesterday afternoon due to a hardware problem. While a CNSS crash of this type would not normally cause users loss of connectivity due to backbone redundancy, this crash did result in connectivity loss since the Ann Arbor interconnect E131 which is homed int o the Cleveland POP became reachable via the safety net T1 links only. The interconnect gateway was switched over to Houston during this time. This resulted in a 25 minute outage of the interconnect. The last T3 router crash we had was several weeks ago and the last hardware induced crash was several months ago. While this is an undesirable event, I suspect that SURAnet's use of the T3 backbone may actually reduce your dependency on the interconnect gateways. We have installed new software (build 64 and new rcp_routed) across the T3 system during the last two weeks with additional performance and reliability enhancements including improved aggregation of interior routing updates, faster convergence time, and reduced CPU utilization. Operationally we have begun the on-call schedule for the new NNAF engineering group which has resulted in some more detailed NSR reports on these scheduled and unscheduled events. This event coupled with the numerous scheduled software installations may have given you the false impression that there was an increase in problems. My general conclusion is that while we have still have some problems with the current T3 adapter technology, this has been manageable and the T3 backbone is still very reliable. We will cautiously monitor the network reliability for changes as we add additional traffic to the T3 system. The T 1 network is not nearly as reliable and we are busy working on those problems. Mark Peer network router problems: 18410 - SURAnet sura7.sura.net 18429 - BARRnet equipment move 18441 - Pittsburgh power failure Backbone router hardware problems: 18423 - cisco serial interface, Xlink (Germany) 18426 - cnss40 spare t3 card removed from backplane to reduce frequency of black links.

Could someone at Merit summarize some of the recent outages if there have been trends, or could some of the other midlevels provide us with some insight as to how (in)stability has affected your connections? We are going with the emerging standard of send T3 stuff to the T3 and T1 stuff to the T1, explicitly importing T3 routes and defaulting everything else to the T1. thanks, dave o'leary SURAnet
