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, codeIf you remain logged into Evernote’s web interface for long enough, eventually you’ll encounter the situation where attempting to save a note after making some changes will result in a little HTML pop-up dialog telling you that you need to “reload evernote” to access a “new version”. If you click the only button on this [...]
Tagged evernote, failI find my Samsung phone’s auto-complete behavior peculiar: For some months now, when I hit ‘h’ instead of ‘g’ when typing ‘get’, it auto-completes ‘het’ as ‘heterosexual’. Then, just a few minutes ago I was typing ‘it’, and got ‘ostensibly’ (no idea how). These can’t be particularly common n-grams in my writing. In fact, I’m [...]
Tagged auto-complete, randomI’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 [...]

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 vodafailYou charged me a R114 connection fee, but it’s been six days since I signed a contract with you, and my cellphone number still has not been ported from Virgin Mobile. I paid, but you didn’t do the work. This morning the Virgin SIM stopped working, so now my friends and co-workers cannot reach me. [...]
