Pcap diff tool
by Bastian Ballmann 31 Jan '13

31 Jan '13

Hi all! Recently we wanted to know the difference between two wireshark sessions to two different destination ips. Wireshark has got the ability to merge two pcap files and diff them if they are from the same connection, but there was no tool to diff pcap files in a more flexible way. I found one from EFF but the download link was broken and the project seemed to be inactive. Therefore I wrote a little Python script using Scapy to do the diffing. It can just print packets or produce a new pcap file and you can tell it which header it should ignore or which side / file. The source code can be found here https://github.com/isginf/pcap-diff Patches, ideas and / or feature requests are welcome. Hope you enjoy it!

ipctl, netinfo & co
by Steven Armstrong 04 Dec '12

Holla zusammen Hab die tools mal auf das geaenderte Komcenter angepasst. Koennt ja mal testen wenn ihr moegt. Beim ipctl gab's eine API Aenderung auf Seite Komcenter weil eine IP mehrere Hostnamen haben kann. Das war vorher nicht beruecksichtigt, man konnte zb nicht pro Hostname (A record wenn ihr so wollt) die ttl aendern, zumindest nicht ueber den Webservice. Einfach mal: ipctl help examples Wie immer, patches welcome ;-) Fuer die die's noch nicht gesehen haben, ich hab noch ein kleines Script geschrieben um uri's zu Lage- und Geschossplan auszugeben. roominfo -h Benutze ich zb so: firefox $(roominfo -f -l CAB/H/88) Zudem hat es unter [1] noch ein script welches wir fuer die automagische DHCP-BD (ISC DHCP) -> netcenter migration vewerwendet haben.

Looking for old smartphones
by Steven Armstrong 12 Jan '12

12 Jan '12

Hi Someone just told me that he has thrown away his old smartphone. Please don't do that. Instead give it to me (or some other geek you know :-). Smartphone's are awesome for tinkering, playing and experimenting. They are packed with sensors, have wifi and more. You can do all sorts of cool and usefull stuff with them. So if you have an old, unused, more or less working smartphone lying around, please send it my way :-) Steven Armstrong CAB/H/88 Or let me know where I can pick it up :-) Best wishes, Steven -- Steven Armstrong Institute of Computational Science, ETH Zurich IT Management & Support Universitaetsstrasse 6, CAB/H/88 8092 Zurich, Switzerland Phone: +41 44 632 25 24

sigh ... So from now on it seems one has to manually install the Java crapp if one needs it :-( Yet another reason to very much dislike Oracle. Cheers, Steven
