Internet-wide port scans
by Florian Weimer 16 Oct '12

16 Oct '12

Are there somewhat reputable service providers for Internet-wide TCP port scans? What's the typical rate per TCP port? (I'm interested in rather obscure services whose identification may need additional probing, and this data is unlikely on file already.) A full scan needs just 0.5 TB of data per TCP port, so "roll your own" is definitely an option. But I expect that any halfway decent hosting provider will start asking questions after the first billion packets or so, and at least over here, broadband access without abuse management lacks sufficient upload bandwidth, making the results difficult to interpret because the measurements would span several days.

CLI Roadmap
by Kasper Adel 15 Oct '12

15 Oct '12

Hello, I have never used any CLI other than Cisco so i am curious what useful and creative knobs and bolts are available for other network appliance Vendors. I guess what makes *NIX CLI/Shell so superior is that you can advanced stuff from the CLI using sed, awk and all the great tools there so maybe this is also one thing missing. Regards, Kim

If you are using APNIC as an RPKI trust anchor, please update your Trust Anchor Set.
by George Michaelson 15 Oct '12

15 Oct '12

If you are using APNIC as an RPKI trust anchor, please update your Trust Anchor Set. APNIC will be switching to a new RPKI 'split' trust anchor system on the 25th of October. This change is needed to align APNIC administered resources with their allocation hierarchy. These resources will also be certified under each responsible parent registry at the appropriate time. In accordance with RFC6490 the old APNIC Trust Anchor Locator, associated certificate and repository will be removed, when the certificate expires on the 28th of October. 5 new Trust Anchor Locator (TAL) have been published. These will be kept up to date as an independent trust anchor set for resources maintained by APNIC. The production cycle will start on the 25th of October. Relying parties must add these new TAL by the 25th of October in order to maintain continuity of validation. If you have any questions please contact me. George Michaelson (ggm(a)apnic.net) Please add the following to your trust anchor set: rsync://rpki.apnic.net/repository/apnic-rpki-root-afrinic-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAuMLL96YV9pf0rZ4Ow/bk cgpoPfsRzkcgmisyCuMUdotHwrp8pepujhohatScRK09ILRrZYCdpX4121MJhqXC P3u3hy9fF0CeARKX/Q82nJccD4dtUp23UcFys8hwJgNYZI910ajkAxwNT//H/TFw oUYbzZGBR7o2awMc7GdQl/j6dgOkV6AfYy5DyDEgOUNHnUxED2rreefL/E2Fr2ST Esar6bTR4Tg4+nVF1PjAkgN0tKZYe4wZ6VmtqV/VTngSLysim6av7ki+JR3cVgVU OqXeh1vPjH2tNu6u9bX37ZrdVb6NBRer9I99IDbKvyhELb6nzo8+Q74zga9HI+Pf QwIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-arin-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAp6vscYtzhe0CfFk5Ro44 llPhsInXtfAxqfYmK7m9V3khkqK3d3/ZAW6pcJm7qW8XhEGl+F5mUeeLIm5JoIhr kT5B5M6uL0VlCCkZJH4h76ybOa83vWITNZEDy9L3c3nK4S+Basu3vYoE4ICXGG+J 7zg5Iw9saV+p03E2w1g16pt1QI3Cnggp6edkeWClEz3aPw/ULOIHb7YmatWwdERl tL9LsuMSKszQLUY7F4XVpxey/rJYAZgzDUh+b6813WAClCkkydNjsbviuekAWJbx sW7Mcw53u30K4g8MP03CjkDOubyoR4Qo99R1UQJCdrRsFKbSSfN/fOA4y7ikc3xs jQIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-iana-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAx9RWSL61YAAYumEiU8z8 qH2ETVIL01ilxZlzIL9JYSORMN5Cmtf8V2JblIealSqgOTGjvSjEsiV73s67zYQI 7C/iSOb96uf3/s86NqbxDiFQGN8qG7RNcdgVuUlAidl8WxvLNI8VhqbAB5uSg/Mr LeSOvXRja041VptAxIhcGzDMvlAJRwkrYK/Mo8P4E2rSQgwqCgae0ebY1CsJ3Cjf i67C1nw7oXqJJovvXJ4apGmEv8az23OLC6Ki54Ul/E6xk227BFttqFV3YMtKx42H cCcDVZZy01n7JjzvO8ccaXmHIgR7utnqhBRNNq5Xc5ZhbkrUsNtiJmrZzVlgU6Ou 0wIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-lacnic-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyoYPp3l3DWyPtLWrmRn4 Oux9hQ5bxd0SX/f6ygHxik+I3eMJP5J0Pr2e500tyXb2uKsX9kDqu/kckr+TUMhV BHd5yAv8OAE3YYEvpz/7uTX7cYy2yUeA76OEP75Y88OIQEzGpPLNpIzDxMggxuDh IhkA5xMiUJgVoEgmWSzR+MuRBjv2422wAGB5GpLgYsOjpwvG0VPmhnE+39+10ucQ CLt0Ny5kOR4an2tkvHjm7rzKDnFm8MWxPzAWESdf+8g7ITzSglqxDNiK5E5rdzNt h1Kvp+9RwaFArw6Ky1A4HhnoplN4EfKwxq0YamuKV0ZTTpWyT2+qDuE6sOfHRbJ0 5QIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-ripe-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAwsQlXmEklLYApoDo7GEa NNTEGFPU5wJpi04iXuga2xn+g/TMLOlyJbjuPYRtRm/7VbRnN3m9Ta+WETy03+Fm EbXzB4xxhJKVik/ARHBnrBWhLyURy8Q5/XplE9cJein37IE1mIsbKM7o/90S225w 7GuvW7T4kjPWYmBFOywHWsfQO1EdsgiJrkz+Ab67ZkdSIiKHkf2UE6/MrbDEj+QK 9+s/vKH8BtDhaLmTWY+bVvfJ3+AWDH6roo1ozbl5yamQFbLOl3ns30f3yOJcNSNu /qgMQRRyp2sXXQovhTy8yqm3LFspaCWnTmQtBieWZwibuOa4Z27A1FzTMst2T4wY /wIDAQAB

Re: Detection of Rogue Access Points
by Jonathan Rogers 14 Oct '12

14 Oct '12

I should probably mention that we do not have any legitimate wireless devices at these locations. I realize that this complicates matters. The most recent one we found was found exactly like Joe suggested; we were looking at an ARP table for other reasons and found suspicious things (smartphones). --JR On Sun, Oct 14, 2012 at 5:30 PM, Tom Morris <blueneon(a)gmail.com> wrote: > I have used the wigle app as a scanning and direction finding tool.. it > works OK.

Is a /48 still the smallest thing you can route independently?
by Jo Rhett 14 Oct '12

14 Oct '12

I've finally convinced $DAYJOB to deploy IPv6. Justification for the IP space is easy, however the truth is that a /64 is more than we need in all locations. However the last I heard was that you can't effectively announce anything smaller than a /48. Is this still true? Is this likely to change in the immediate future, or do I need to ask for a /44? -- Jo Rhett Net Consonance : net philanthropy to improve open source and internet projects.
