If you want to run the same command on a number of routers (let’s say you want to check whether a particular prefix is visible on a number of different looking glass/route server hosts) then calling RANCID’s clogin from a loop can save a lot of typing. This probably already exists, but I felt like [...]
Tagged bash, bgp, codeI’ve made some updates to the route servers page. There were enough changes to warrant a quick blog post, so here goes: MTN collapsed AS2905 into AS16637, so lg1.za.mtnbusiness.net now lives in the latter AS lg1.za.mtnbusiness.net now has more liberal command authorization lg1.za.mtnbusiness.net has a new password: l0ok1ng-G145s (1337 5p34k much?) I added the AS37105 [...]
Tagged bgpWhile attending AfPIF 2012, I was motivated to update the original map I did back in 2009. Click on the image to download the PDF version. What is this? This graph shows who provides transit to whom, within South Africa, to the rest of the Internet. I think it needs a lot more work (including [...]
Tagged afpif2012, bgp, mapIn the good old days, ISPA used to have a table with the IP allocations for JINX peers on their website. Now you can use this script: #!/bin/bash # Simeon Miteff, Tue Aug 21 09:46:59 SAST 2012 # simeon@localloop.co.za function getptrv4 { for i in {1..255}; do PTR=`dnsname $1.$i`; [ -n "$PTR" ] && [...]
Tagged bash, CINX, ispa, JINXIn preparation for AfPIF 2012 I’ve been giving the autonomous systems list some TLC. The numbers (prefixes announced, equivalent number of /24s) are now up-to date. Below are the 62 new local ASNs that appeared in BGP-sphere in the two or so years I’ve been busy with other stuff. The as-names are still missing and [...]

Tagged cinnamon, gnome, hipsters, kde, lxde, macosx, mate, unity, xfceA reader contacted me asking more details about the IPv6 hit I received from Web Africa on World IPv6 Day, and that prompted me to take a closer look. Actually that request, as well as the one that I thought was from MWEB, were both from hosts on their networks connecting via tunnels (6to4 for [...]
Tagged IPv6, MWeb, Web AfricaIn a comment to my previous post, Adrian pointed out that localloop.co.za’s DNS is not IPv6-ready, so I hereby officially eat my words. It was, however, a successful experiment. A few things I learned: I actually got some IPv6 visitors! I was not expecting any, never mind South Africans coming from ISP-routed blocks, so this [...]
Tagged IPv6Tomorrow is World IPv6 Day. The big deal (apparently) is that some providers will be temporarily running IPv6 in parallel to their IPv4 services. The protocol has been around for 15 years, and now they’re have a whole “world day” to turn it on, and then they’ll turn it off again. Cowards. For tomorrow, I [...]
