Life the Universe and Everything

Monday, July 9th, 2007

Today I realized that even though the world is cruel and unfair, irony is not lost. I realized this while I was sitting on hold with my ISP, and the rep came back on the line and told me the reason why I had to hold a little longer was because he himself was on hold…… 5 minutes later he hung up on me while transferring my call….?

Open Solaris 10 sandbox

Monday, July 2nd, 2007

Thanks to those friendly people from Digg.com who decided it would be fun to bring my Solaris box to its knees by forking and other things to DDOS my Solaris zone. I have learned many ways of enhancing the security of Solaris zones. I have limited the Sandbox zone to 1% of total CPU usage. I have limited the total number of processes to 1000 and I have installed the Solaris Jass security hardening script. I plan to post many of my discoveries in the future. Work has been busy lately and it is on the burner of things to be done along with part 2 of solaris zones.

First Production ZFS server today

Monday, July 2nd, 2007

I have plenty of small business clients and sooner or later they all face one big challenge. They all outgrow the initial 80GB tape drives that we put on their servers. The problem is that most of these are small businesses and most of them could just afford the initial network, and asking them to pony up $2000+ for a new tape drive or worse yet autoloader is out of the question.

TV Networks Just Don’t Get it

Monday, July 2nd, 2007

I t seems to me that the big four tv network either don’t understand what people want or simply don’t care. If you look at the cable networks you have stimulating things to watch like Nip Tuck, Dexter, Sleeper Cell, Battlestar Galactica, Monk, and too many other good dramas to mention. However when you turn to the major networks they simply show one copied worn out reality show after another.

Until recently I assumed they just didn’t get it, but then I found out that it cost the networks on average 4 to 8 times as much money to produce a script based show. Kind of makes you think doesn’t it?

Things I Wish I Knew About Solaris When I First Started.

Monday, July 2nd, 2007

Solaris 10 is a very powerful scalable operating system that feels tightly integrated and highly responsive. However for those of us with a strong Linux or FreeBSD background Solaris can feel a little unfamiliar and even downright confusing. This post is made up of a few things I wish I knew before I started my Solaris 10 adventure. I hope it will make things a little easier for those of you wanting to take the plunge into a true enterprise operating system.

More…

1.That annoying backspace!!!!

If you are wondering how to get the backspace key to work in Solaris you can type one simple command. It should make life much easier for you.

#stty erase ^h

The (^h) is what is displayed when you use the backspace key.

2.How do I enable Samba?

To enable Samba simply issue the following commands:

#vi /etc/sfw/smb.conf

Enter your samba config entries here

#reboot?

When Solaris 10 boots it will check /etc/sfw for the smb.conf file, If that file is present it will enable samba automatically.

3. How do I turn the graphical login on and off on bootup?

If you want the gui to not start when the system boots you can issue the following commands.

#/usr/dt/bin/dtconfig –d

The above command will disable auto gui on boot.

#/usr/dt/bin/dtconfig –e

As you can probably guess if –d disables the gui –e enables it.

4. How do I scan for a network card and load the driver?

If you are coming from Linux or FreeBSD the process of loading a network card driver may seem very alien. In order to check for any network cards on the system for which you have drivers you can issue the following commands

#ifconfig –a plumb

The plumb part of the command will look for any network cards for which you have drivers and attempt to attach the driver to the hardware. You can check to see if any cards were found by using the following command.

#ifconfig –a

If any new network cards were found they will now show in the above command. The trick here is to get the network card to load automatically every time the computer starts in order to do this you must create the following file.

#vi /etc/hostname.interface-name

some examples of this are:

Hostname.rtls0Hostname.vfe0

Inside this file you need to put the hostname of the computer.

If the hostname is workstation1.techinvasion.net the file should look like the following:

#cat /etc/hostname.vfe0Workstation1#

These Are just some of the things that I have learned that I wish I knew when I started my adventure into Solaris. I will add more little tips to this page as I find more little things to add.
