I’m at CCSP today, my name is in the list of presenters for two sessions, but I’m really only talking at one session.

Streaming after report
Peak clients
The dry-run live streaming event that happened on the 10th went well. With very little in the way of advance publicity, we peaked at about 40 clients and I’m not sure we ever handed any clients off to any of the other servers. Next up is something on May 13th, hopefully.
Windows Server 2003 and Exchange 2000
It’s not my job anymore, but I can’t pass up the opportunity to comment on KC’s post about Exchange 2000 and Windows Server 2003.
I’ll count myself as one of those customers, though I never got a chance to comment directly to KC or anyone else at Microsoft. But, it’s good to know that MS isn’t always just a looking for another way to make a quick buck or using forced obsolescence. Also, I can only imagine what happens when someone two or three levels above you tells someone else two or three levels above them that you said it can’t be done.
Some history
I was going through some old mail archives and I found this:
Date: Tue, 29 Apr 1997 01:02:01 -0500
Subject: Auto Reset of ipfwadm stats
Tue Apr 29 01:02:01 CDT 1997
Stats for yesterday:
IP accounting rules
pkts bytes dir prot source destination ports
144 28693 i/o all ppp01.hoopeston.k12.il.us anywhere n/a
7336 2332K i/o all ppp02.hoopeston.k12.il.us anywhere n/a
0 0 i/o all ppp03.hoopeston.k12.il.us anywhere n/a
0 0 i/o all ppp04.hoopeston.k12.il.us anywhere n/a
That’s just the earliest mail I can find, it was running before April. Hard to believe we’ve had dialup running in Hoopeston for more than 10 years.
Using the Rack
Rack
Mentioned more than 2 years ago, we’ve finally started to use it. Jim and I are migrating as many of our physical machines to VMware Server virtual machines hosted on very nice Dell PowerEdge servers running CentOS 4.4 as we can.
I kind of thought I was getting away from this kind of stuff when I left Housing, but obviously not.
Streaming
Actual streaming clients
One of the “services” I’m responsible for has been floating adrift for a couple of years without any real users. When it was handed to me, it came with a directive to support the campus Multimedia Users Group, and we are starting to ramp up. There will be a dry-run, proof-of-concept event streamed live April 10th at 4:00 pm. You’ll need Real Player or Real Alternative (preferred) to watch it. Hopefully I’ll have a URL posted here later today…
Status note
I kind of have to note the fact that I can, and have, posted a note on the CITES status server.
Of course, it’s not for the service I was hired to manage, but that’s a different discussion.
Shoretel VoIP evaluation
The last few days at work have put the DNS RFP on the back burner and pushed me towards learning lots of new terms: DID, PSAP, NANP and ACD.
So far, the setup for the eval seems to be going well, the onsite technical guy from the vendor knows his stuff and the right people to call when he doesn’t know the answer. We’ve had a couple bumps in the road from Ameritech, T1 PRIs and the goofyness that is the campus Centrex system. But, we’re working around them and hopefully deploying phones to ~15 people between now and Friday. Shoretel essentially sent us one of every product they make in the VoIP sector, and we’re trying to put it all to good use.
Hopefully, I’ll remember to post about the outcome of this evaluation, assuming I’m allowed to by the NDA I have to sign at some point.
It’s been awhile
It’s been quite some time since I’ve put anything up here, so this may end up being a rambling mess.
Hoopeston Area lost a good superintendent last Saturday to an apparent heart attack, Mr. Conolly will be missed.
At CITES, I’ve been working on an RFP for a solution to support our DNS infrastructure. The most I can do is to link to a similar effort being run by The University of Michigan. Hopefully ours will be on the street sometime in January, then I get to work on a committee to evaluate the proposals and maybe some evaluation equipment.
On consulting sites:
- Hoopeston Public Library has a recently reinstalled IPMasq/Squid box and new “free” wireless service powered by PublicIP’s ZoneCD.
- Crown Ford and the other dealerships in Hoopeston are now using OpenVPN for securing the traffic between them and we are actively monitoring the bandwidth usage on those links.
The holidays are coming up, I’m not sure what to get anyone, as usual. Hopefully the utilitarian gifts and gift certificates will work again this year. Now, if we can just make it home without borrowing a trailer to haul Robin’s gifts in.
And, as usual, I’m way behind on getting pictures of Robin posted. Maybe next week after we’re done driving all over the Illiana area…
Script-fu
So, you want to turn a 14,000 line logfile with 9300 lines like the following, into a summary of the most often seen ip addresses?
Oct 23 01:04:36 nameserver.dept.uiuc.edu in.named[26133]: [ID 873579 local1.warning] client 192.168.0.4#52241: no more recursive clients: quota reached
Oct 23 01:04:36 nameserver.dept.uiuc.edu in.named[26133]: [ID 873579 local1.warning] client 192.168.0.5#52241: no more recursive clients: quota reached
Here’s your one-liner, showing just the top 10 hitters
cat /services/dns/log/named.20061023 | grep 'quota' | tr -s " " | cut -d " " -f 10 | perl -pi -e 's/(.*)#.*/$1/' | sort | uniq -c | sort -n | tail
and it’s output:
161 192.168.254.29
163 192.168.5.119
167 192.168.172.72
201 192.168.5.12
223 192.168.5.138
257 192.168.0.7
298 192.168.181.2
307 192.168.0.9
905 192.168.252.5
2630 192.168.252.4
