New BCOPs in Progress
by Chris Grundemann 25 Mar '15

25 Mar '15

Hail NANOGers! As most of you hopefully know, NANOG now has a BCOP Ad Hoc Committee and we are pushing forward with new BCOPs! http://nanog.org/governance/bcop We currently have three BCOPs in active development: eBGP configuration, shepherd Bill Armstrong Public Peering Exchange update, shepherd Shawn Hsiao Ethernet OAM, shepherd Mark Calkins All three of these nascent BCOPs will be presented in the BCOP Track on Monday: http://nanog.org/meetings/abstract?id=2348 We have also collected a list of Appeals (BCOPs that need to be written): http://bcop.nanog.org/index.php/Appeals If you would like to help out with any of these BCOPs (or others yet to be identified) please join the BCOP mailing list and reach out to the shepherd (if applicable of course): http://mailman.nanog.org/mailman/listinfo/bcop Our committee is brand new and we are still finding and smoothing wrinkles, etc. We would love your help in any capacity. As a BCOP shepherd or SME or just to point out potential pit falls or room for improvement, with the process, the wiki, a BCOP or anything at all really. This is a bottom-up, community led effort and it will only succeed with your help - join us in creating what I believe will be a vital and long-lasting institution! Cheers, ~Chris -- @ChrisGrundemann http://chrisgrundemann.com

The state of TACACS+
by Robert Drake 05 Jan '15

05 Jan '15

Ever since first using it I've always liked tacacs+. Having said that I've grown to dislike some things about it recently. I guess, there have always been problems but I've been willing to leave them alone. I don't have time to give the code a real deep inspection, so I'm interested in others thoughts about it. I suspect people have just left it alone because it works. Also I apologize if this is too verbose or technical, or not technical enough, or just hard to read. History: TACACS+ was proposed as a standard to the IETF. They never adopted it and let the standards draft expire in 1998. Since then there have been no official changes to the code. Much has happened between now and then. I specifically was interested in parsing tac_plus logs correctly. After finding idiosyncrasies I decided to look at the source and the RFC to see what was really happening. Logging, or why I got into this mess: In the accounting log, fields are sometimes logged in different order. It appears the client is logging whatever it receives without parsing it or modifying it. That means the remote system is sending them in different orders, so technically the fault lies with them. However, it seems too trusting to take in data and log it without looking at it. This can also cause issues when you send a command like (Cisco) "dir /all nvram:" on a box with many files. The device expands the command to include everything on the nvram (important because you might want to deny access to that command based on something it expanded), but it gets truncated somewhere (not sure if it's the device buffer that is full, tac_plus, or the logging part. I might tcpdump for a while to see if I can figure out what it looks like on the wire) I'm not sure if there are security implications there. Encryption: The existing security consists of md5 XOR <content> with the md5 being composed of a running series of 16 byte hashes, taking the previous hash as part of the seed of the next hash. A sequence number is used so simple replay shouldn't be a factor. Depending on how vulnerable iterative md5 is to it, and how much time you had to sniff the traffic, I would think this would be highly vulnerable to chosen plaintext if you already have a user-level login, or at least partial known plaintext (with the assumption they make backups, you can guess that at least some of the packets will have "show running-config" and other common commands). They also don't pad the encrypted string so you can guess the command (or password) based on the length of the encrypted data. For a better description of the encryption you can read the draft: http://tools.ietf.org/html/draft-grant-tacacs-02 I found an article from May, 2000 which shows that the encryption scheme chosen was insufficient even then. http://www.openwall.com/articles/TACACS+-Protocol-Security For new crypto I would advise multiple cipher support with negotiation so you know what each client and server is capable of. If the client and server supported multiple keys (with a keyid) it would be easier to roll keys frequently, or if it isn't too much overhead they could use public key. Clients: As for clients, Wikipedia lists several that seem to be based on the original open-source tac_plus from Cisco. shrubbery.net has the "official" version that debian and freebsd use. I looked at some of the others and they all seemed to derive from Cisco's code directly or shrubbery.net code, but they retained the name and started doing their own versioning. All the webpages look like they're from 1995. In some cases I think it's intentional but in some ways it shows a lack of care for the code, like it's been dropped since 2000. Documentation is old: This only applies to shrubbery.net's version. I didn't look at the other ones that closely. While all of it appears valid, one Q&A in the FAQ was about IOS 10.3/11.0. Performance questions use the sparc 2 as a target machine. There isn't an INSTALL or README, just the FAQ/CHANGES/COPYING (and a tac_plus.conf manpage), so the learning curve for new users is probably pretty steep. Also there isn't a clear maintainer. The best email address I found was listed in the tacacs+.spec file, for packaging on rpm systems. If you hit the website they give some hints with some outdated, though still functional links. And they list the official email as tac_plus(a)shrubbery.net Conclusion: Did everyone already know this but me? If so have you moved to Kerberos? Can Kerberos do everything TACACS+ was doing for router authorization? I've got gear that only supports radius and tacacsplus, so in some cases I have no choice but to use one of those, neither of which I would trust over an unencrypted wire. If TACACS+ isn't a dead end then it needs a push to bring the protocol to a new version. There are big name vendors involved in making supported clients and servers. There should be someone invested in keeping it secure and adding features.

Is it unusual to remove defunct rr objects?
by Tim Howe 03 Nov '14

03 Nov '14

In the recent past, we've had another provider in our same market erroneously advertising prefixes for some of our customers. After we got it cleared up, I noticed that there were some old route objects in RADB that were entered for that provider years ago by 360. These route objects, in a sense, legitimized, the erroneous advertisements by matching the prefixes to that providers ASN. As that provider no longer uses 360/Zayo, I asked Zayo if they could remove the objects. Once the request made it to someone who understood what I was asking, they spent some time and effort over the next few weeks (much appreciated by me, I might add) in hunting down the info they needed to (I assume) manage the old 360 maintnr object. They then removed the offending objects (again, my thanks). One of the Zayo support folks mentioned to me, somewhat apologetically, that it took some time as nobody had ever made such a request before. So this got me wondering: is it really such a rare thing to manage ones route objects such that old defunct data is removed? I'm not under the impression that the issue I had would have been alleviated any by the related route objects having been removed beforehand, but their existence wasn't helping me any either. I've since found a disturbing number of defunct objects that relate to my customers (and me) in a similar way, and I have mostly had success in getting them cleared up. If my relatively small customer base is any indication, there are more incorrect objects out there than correct ones. I feel this is something I should have been looking into sooner. Is this a non-issue that I shouldn't worry about? Doesn't the quality of this data effect Origin Validation efforts? Sorry that this turned out so long; I wanted to give some context. --TimH

Industry standard bandwidth guarantee?
by keith tokash 02 Nov '14

02 Nov '14

Hi *, sorry if this has been answered, I did look. Is there an industry standard regarding how much bandwidth an inter-carrier circuit should guarantee? Specifically I'm thinking of a sub-interface on a shared physical interface. I've not thought much about it but if there's a more generally-accepted guideline than, "when the customers start leaving / when you leave," I'm at least 5% ears. Thanks, Keith

Hijacking machine: ASAS201640 / AS200002
by Ronald F. Guilmette 01 Nov '14

01 Nov '14

I don't routinely follow this list, so I'm not sure how much of this is common knowledge already, but... http://blogs.cisco.com/security/talos/help-my-ip-address-has-been-hijacked/ Current route announcements for AS201640: 36.0.56.0/21 probable hijack - China 41.92.206.0/23 probable hijack - Cameroon 41.198.80.0/20 probable hijack - South Africa 41.198.224.0/20 probable hijack - South Africa 61.242.128.0/19 probable hijack - China 119.227.224.0/19 probable hijack - India 123.29.96.0/19 probable hijack - Vietnam 177.22.117.0/24 probable hijack - Brazil 187.189.158.0/23 probable hijack - Mexico 202.39.112.0/20 probable hijack - Taiwan Network Information Center 210.57.0.0/19 probable hijack - Telstra/Japan It would appear that AS201640 may possibly exist at the present time only for the purpose of providing illicitly obtained IP space for spammers, including but not limited to the ""Mike Prescott" mentioned in the Cisco blog entry cited above. The spammer, "Mike Prescott"... not his real last name... has also been spotted spewing from IP space routed by AS200002, which is AS201640's only connection to the rest of the world. Coincidence? You be the judge. Regards, rfg P.S. If anybody is able to look up _all_ of the route announcements that have been made by AS201640 over the past few months, I for one would definitely like to see those. Please e-mail them to me off list. I already know that "Mike Prescott" has been spewing from at least one of the above current announcements (202.39.112.0/20) and probably all of the others too. But there are additional route announcements that have already been withdrawn, and I'd like to check those for "Mike Prescott" footprints also. P.P.S. To the real "Mike P."... on the off chance that he might see this... You can run, but you don't hide very well. You should have gotten out of the game in 1998 when you had the chance. Maybe the Powers That Be will lock you up this time.

Comcast throttling?
by Mark Price 31 Oct '14

31 Oct '14

Similar to another thread on the list today, I'm troubleshooting a problem for a customer on Comcast business fiber. Downloading a file from one of our web servers is very slow (~15KByte/sec). mtr looks clean in both directions. I added an IP address on the same server from a different class C on our network, and downloads form this new IP are fast (2MByte/sec). Tracerouting from server to client is the same using both source IPs. But, one IP consistently has the very slow speeds that the other does not. Changing our outbound path between different upstreams does not make a difference. It certainly feels like Comcast is throttling one of our IP ranges. Could someone at Comcast please contact me off-list for details? Thanks, Mark

Comcast Enterprise Fiber Slow Connection Problem from TW Telecom
by Zachary Frederick 31 Oct '14

31 Oct '14

We have been having a problem receiving software releases from our developer. The releases are typically around 1G in size. The developer’s connection is a 100m metro fiber with TW Telecom, our connection is a 25m Comcast Enterprise Fiber. Our traffic graphs show very little utilization of our connection. Typically on average we are at about 7 meg utilization of our 25. Every other partner that shares in our software development that receives the software releases can receive the updates 3-4 times faster than we can. Typically we receive the releases at about 3mbps. I have tried contacting Comcast Enterprise Tech support, however I’ve been told that if I run a speed test from my connection and the test runs at the speed we are paying for, there is very little they are willing to look into. Can anyone check on the Comcast Routers on the Tracert below, or is there anything that can be throttling this connection between the two connections? Also, our firewall and connection is able to run at the full 25. We have no throttling or QOS set to prevent a good connection to our developer. For example, we can run a multi-threaded upload, in the middle of the night, to Amazon Glacier storage and completely saturate our connection when doing so. The firewall and connection is able to handle our full bandwidth capacity during that backup. If there is any other information I can provide to help track this problem down, please let me know. Thanks in advance, everyone!
