tpg.com.au contact?
Anyone have a clueful mail admin contact for tpg.com.au? The usual attempts result in completely clueless and unhelpful responses, going round in circles with no progress. -Dan
STP Visualization
Can anyone recommend a good tool for spanning tree visualization? I am needing to get a good visual depiction of forwarding for many vlans, across 4 core switches. Two of them are CatOS, 2 are IOS, root is different for many of the vlans, lots of port costing in place, in other words it would take a while by hand. Thanks, Brian

Re: STP Visualization
Although that looks like a pretty cool visualization program, I does not have the ability to automatically grok STP info via snmp/ssh/ telnet/cdp/etc. I am looking for a program to do the work of showing me STP forwarding paths on a per vlan basis, it doesn't have to be pretty, just something that can do it.

Note due a bunch of stuff not being uniformly implemented in IOS via SNMP I've had to screen scrape a little and I'm afraid this means I don't have any CatOS support. Let me know offlist if you are interested in the code. I have something to do this as well, using perl to grab all the details via SNMP, and then visualization using GraphViz. You're welcome to use it to start with: http://net.doit.wisc.edu/~plonka/stpgraph/ There's a sample PDF in the examples/ sub-dir. Dave P.S. I know initially you request a good tool, which is in the eye of the beholder. This one will want a programmer's eye, I guess. -- plo...@cs.wisc.edu http://net.doit.wisc.edu/~plonka/ Madison, WI
DNS query analyzer
Hey List! Anyone know of a tool that can take a pcap file from wireshark that was used to collect dns queries and then spit out statistics about the queries such as RTT and timeouts? Thanks! Joseph

Not off the top of my head, but, you could use wireshark's Lua extension system to write a plugin to do this for you right within wireshark. The wireshark/Lua stuff is quite powerful (though not super super fast), it's a really useful tool to have on hand. -- Nathan Ward

It just so happens there is a tool aptly named DNS Analyzer by NLnet Labs. I used it a while back but if I recall you could feed it a pcap and it could spit out all kinds of useful statistical data. I don't think it's being actively maintained at the moment but you should be able to find it on the NLnet Labs site - http://www.nlnetlabs.nl/projects/dns-analyzer/ HTHs.

It would be nice if we could convince them to release the source code into the public domain. I'm sure there are a few people who would find it highly useful and would work on it to add to its utility. The source (versions 0.2.0 and 0.3.0) is available at the above URL and there is a GPL license in the tarball. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV

Nothing with RTT and timeouts in this, but it could probably be adapted with an additional, rudimentary subroutine to try summarizing that too: http://www.cymru.com/jtk/code/pcapsum.pl If you or no one else comes up with something or modifies this to do it, give me a holler and I'll whip something up for you. As is, it'll count DNS messages, header flags and give a top X list of qnames seen. It uses the somewhat limited NetPacket modules, but it would be easy to either switch wholesale to the Net::Packet modules or pull in just those needed (e.g. VLAN and IPv6 support). It is what it is, hopefully its of use. John
