New Servers Now Serving the Public

Sunday, September 30th, 2007

aaaaah…..and no i can’t say too much about that. But they are Sun T2000s and are handling it really well.

We are half way through our deployment so everything is going well. Except that all of us have sacrificed our Friday nights/Saturday mornings….4th in a row and will continue up to and including October 19th.

I won’t be working that day…i’ve negotiated it off…hopefully…but geez….8 Fridays and Saturday mornings in a row is too much….

What more can i say?

Dodging Trees

Trees May Fall

I decided to go for a drive to the Eastern forests of Victoria (Yarra Ranges, LaTrobe State Forest) and go hiking for a few hours as i’d worked quite late until 2:30am this morning and needed to get out.I drove to Noojee and went up one of the tracks i know up there and intended on taking a link track to where i was going to go hiking.

Yeah right!

There was a a bit of bad weather here last weekend and trees were blown over everywhere. I got through most of them and had to move some, pull out the axe on others but a few i couldn’t move and they scratched my 4WD LandCruiser pretty badly. These new “Pin Stripes” i have now acquired should polish out, but i got to a point where there was a large tree across the track and i had to turn around.

Securing Solaris 10 Zones

Friday, September 21st, 2007

and they’re called “containers” too.

even if you have your Global zone secured “to the max” if you created a new Zone under Solaris 10 11/06 and before, the Zone/Container will be enabled with all the services switched on. Those pesky services like telnet, ftp and co.

Your Security Department will audit your servers and freak out. So all you need to run inside the Zone/Container is the netservices script:

netservices: usage: netservices [ open | limited ]

and in our case you run: netservices limited

And what this effectively does is issue a svcadm disable command to the services identified by the command.

Easy. Although SSH is enabled. Some security Nazis don’t like that running in a zone/container. It’s up to your local security policy as to whether or not you have sshd running.

Working 27 Hours A Day for The Bank

Thursday, September 20th, 2007

I work at a Large Bank.

There, i’ve said it. We are short staffed where i work and we’ve undergone a restructure. My “old” department is 3 or 4 people down and i recommended a guru that i’d worked with years ago and that had worked at the Bank and recommended him to help alleviate the loss of staff (2 very key and senior people left) and also ‘coz this guy had worked here before, knew the environment and would have no issues in getting up to speed. I’m the only senior person left now.

Nirvana

Monday, September 17th, 2007

I’ve just watched yet another expose on Kurt Cobain and of course Courtney Love is mentioned. How can they blame her??

Fuck off.. Who knows what happened there. Yes i was disappointed that that he chose to end his life…..and yes i had all the Nirvana CDs and had Holes’ CDs but hey….i think the documentary that i saw shows how overwhelming fame and stardom can become.

No one can know for sure, but they had people that were interviewed that were addicts and ex-addicts and well the Exodus people were there…so who knows?

Weird Routing Issues in Solaris 10 Zones

Monday, September 10th, 2007

We’ve had some weirdness happening on 2 of the 6 servers and only in some new containers/zones. Traffic is being routed out two interfaces instead of one. Network sniffers confirm it and issuing curls of the URL sometimes works, sometimes not.

RRR – Subscriber Radio

Friday, September 7th, 2007

I renewed my subscription to RRR yesterday. It’s a good cause and i was listening to Nicky (‘scuse speeling) on the Graveyard Shift at the time. She plays a good selection of tracks. If you are up late/early for some reason then tune in to the Graveyard Shift on 102.7 FM. Otherwise, jsut tune in! They play great music. No commercials (ads) except for their own sponsors of course.

Recovering a ZFS zpool after a UFS root failure.

Wednesday, September 5th, 2007

I had a Sun T2000 CPU panic while i was moving some files from a UFS filesystem to a ZFS filesystem. The UFS filesystem had reported some issues during the day.

This lead to a corrupt root UFS filesystem on both its disks and the server was unrecoverable.
