Enabling IPv6 on Cisco 3750 and Solaris/Linux/Windows

Alright, lately one of my goals for this quarter is to get our lab working over IPv6 in addition to IPv4 for testing some of our software. Here’s a quick rundown on how to enable ipv6 on *most* cisco switches and Solaris, Linux and Windows.

Enable IPv6 on *most* Cisco switches (I used a 3750):
1. Telnet to the switch
2. Use “enable” to escalate privledges
3. configure terminal
4. sdm prefer dual-ipv4-and-ipv6 routing
5. end
6. reload (this will reboot the switch)

If you need to make sure it’s set correctly, telnet into the switch, enable and then run “show sdm prefer” and verify that it’s running ipv4-and-ipv6.

Enabling IPv6 on Solaris:
1. touch /etc/hostname6.<interfacename>
<interfacename> is the name of the hardware interface, something like ce0 or e1000g0, etc.

Enabling IPv6 on RedHat Linux
1. system-config-network, select the interface, edit the properties and check the box that says “Enable IPv6 on this interface”

Enabling IPv6 on Windows
1. ipv6 install at a command prompt.

You can test it using ping on Solaris and ping6 on Linux and Windows. Good luck!

Recent home project: ZFS NAS server

I apologize for not posting for the last week, it was a very hectic week for myself because of a certain request for a Solaris 9 machine with tape that took the greater part of a week to get working properly. All I have to say about that is that I much prefer Solaris 10 over Solaris 9.

Anyhow, on to the project. Lately I’ve been working on an old Blade 150 that I have at home trying to get it to recognize the IDE controller card and old hard drives attached. Below you can see a picture of what I’m working with:

Blade 150

I have an UltraSPARC II processor in there running at 650Mhz as well as a gig of RAM (hopefully enough for my purposes). I found an extremely old IDE RAID controller card, switched it to JBOD mode and stuck it connected to 2 spare hard drives. At this time the hard drives are each only 40GB and I haven’t figured out a way for them to stay in the case (not enough space in there). I ran the IDE cables through the PCI slot opening and set the drives on top.

One of the problems I ran into was powering the hard drives, in this case the 150 didn’t have enough spare power hookups for 2 additional drives (in addition to the one inside the machine for the OS), so I ended up gutting another machine of mine for the power supply to power only the hard drives. Slightly out of the picture on the left the power supply is sitting with a paper-clip jammed into the motherboard connector to manually switch it to “always on”. Not a very elegant solution, but for the time being it works. Hopefully I’ll be getting a case for the hard drives and additional power supply so it doesn’t look nearly as ugly.

Anyhow, after installing OpenSolaris build 65, the machine booted up and was able to see the additional 2 hard drives, but panicked and rebooted when I actually selected them, upon rebooting they acted alright. I proceeded to create a mirrored zpool in case of drive failure. At this point it’s only 40GB, but I plan on getting some 300-500 GB drives for the data. Eventually I want this to be shared across the network for Delilah and I to store our important documents on (and it will be backed up also). Definitely a very cheap solution for our simple home.

Does anyone out there have a home server running Solaris? What do you use it for? How does it work out?

Thanks to my beautiful wife Delilah for taking the picture while I was at work!
