Free Geek Server Rack Build PART THREE!!!!

Yes, yes, I know. Two months have gone by since the last entry about Free Geek. Well finally I had some time to make it down there and to my enjoyment though Tyler from Free Geek had been busy at work. He managed to do quite a bit of work while I was away. Here’s a pic and some highlights!

6 port KVM

16 Bay SATA disk pool server

The UPS has been racked

Gigabit backbone switches are in place

All the servers have been wired in the back

All running Ubuntu Server 10.04 LTS

Fancy fancy LCD and keyboard tray (ooooh aaaaaah)

Complete radicalness! (FTW!)

All the HP iLO’s have been configured

AND color coded ethernet cabling! (BAM!)

NFS storage raid with lots of space and redundancy (BAM! BAM!)

Enough hardware to run two Free Geeks!

And some Tyler secret tricks!

Now first I must mention something that happened which was spectacular. I showed up to Free Geek with tools in hand ready to kick ass and chew bubblegum. I said ‘Hi’ to the gang and then got right to work going over what’s been done already and what we should do for the day. Then I heard a small voice coming from behind me. It all started with a simple ‘Hello.’ Tyler and I turned around and here stood this lady, she said that she had heard we were doing updates to the network and wondered if she could help. I have something to confess here, I judged at first sight. So my initial response was ….. uhhhhhh….. and in my head I was thinking “oh god I have SO much to do today, I can’t possibly teach and babysit someone else.” However we said ok you can help

“what’s your name?” I asked

“Vicki” she replied.

I said “OK, Vicki, I’m going to outline on this whiteboard what we hope to accomplish today.”

I then began drawing out network topologies and what VLAN’s we were going to roll out that day. Tyler pulls up a network diagram I had done up briefly a few weeks ago to talk about subnet allocation and service assignments. All the while Vicki was quietly watching and listening. We then went about which of our new servers would be responsible of what task, such as “teak” was going to be our new LDAP and DNS server, maple the new NFS server, how authentication was going to happen for autoFS mounts and so on. Granted if you’ve been in this industry for a while this isn’t super complex stuff, LDAP migration, network topology planning, thinking ahead for future departments, etc etc. However, this isn’t childs play either, let’s be honest there are a lot of ‘sys admins’ out there and not all of them could roll out a network of this size.

We turned to Vicki and started going thru the tasks on the board, expecting (I was anyway) to see a lot of confusion. BUT NO! OMG! She knew just as much, if not MORE about this stuff than we did. In fact, over lunch we got into a discussion about proper use of VLAN’s and subnet routing between them. This woman was (is) AMAZING! It was like the network God looked down from heaven and with his noodley appendage, blessed our tech mecca for that day by sending us a worker! A worker that new how to install services, write config files, test connectivity and map VLAN’s!!! Quite literally she cut our work time by 40% if not more. If anyone needs a good sysadmin, or network engineer who knows their way around a linux terminal and learns by being shown ONCE! Contact me, I’ll send her details on to you.

Anywho, Tyler and I laid out the VLAN’s and what they would be responsible for. We had configured three switches thus far to trunk all the VID’s but when we got to the fourth and final switch, we had no admin credentials for it. (My fault!) Our plan at that point was to wait until the end of the day, reset the switch, recover the password and then move our core router to the rack. In the meantime I checked up on Vicki and she had gotten all of our services, OpenLDAP, bind, Zenoss, apt-cache, TFTP server, and some other stuff up and running and was ready for configuration. I migrated the database from an older version of OpenLDAP with a slapd.conf file to the new version with the slapd.d directory.

Once the Free Geek came to an end Tyler and I moved the router from the bathroom server room to the upstairs rack, pushed the ADSL modem thru and VLAN, and then made an LACP trunk to our OpenBSD router. Put the VLAN interfaces in place and POW. Network configured. (For the most part) The final stage is migrating the servers to the proper VLAN’s and updating their services configurations.

The next and final post will be mostly diagram based. Stay Tuned! HOPEFULLY the next post will be really insightful IF I can get Luke and Kamil from Zymeworks to donate some time into rebuilding our Asterisk server and implementing a KDC
