I’ve been working with Unix for a fairly long time now- about 13 years.
I’ll admit that I started with Linux and thought it was light years ahead of SunOS 4.x running on those old SPARC machines- I mean who had heard of SPARC processors? I remember my boss trying to explain to me that even an older SPARC processor was more powerful than a newer Intel Pentium processor. I didn’t really believe him. In time, I convinced them to get rid of most of their SPARC/Solaris in favor of the hip, free, and cheap Intel/Linux combination.
Now I see that I couldn’t have been more wrong. I realize that SunOS 4.x probably still has features which I don’t know how to use properly. When I look at Solaris 10, ZFS, Zones, LDOMS, DTrace, etc. I not really sure you could pay me to work with Linux (that would be soo depressing). That isn’t even mentioning the SPARC hardware it runs on- Can any Intel server compare to a T5140???
That’s why the current situation with Sun absolutely SUCKS (pardon my french)! I’m sure there are a lot of admins out there who feel the same way. If this Oracle deal doesn’t go through and Sun disappears because of it, it will be our loss. We’ll be stuck with mediocre operating systems and commodity hardware and I really hope it doesn’t happen.
That said, I’d like to say thanks to all the people at Sun who are still turning out crazy cool technologies despite the problems.
If you’ve ever wondered how to determine your current run level, use the command
This works for Solaris and Linux (at least the ones I’ve tested)
I recently installed Solaris 10 06/06 x86 on my desktop machine, a Compaq Evo with an onboard Intel 10/100 network card.
At first the Solaris installation seemed to hang while trying to find a network configuration from a non-existant RPC boot server. In retrospect, I think the problem was that Solaris didn’t find an appropriate driver for the card but after waiting a long time, the installation continued skipping the network configuration.
Running prtconf -pv shows the pci identification details for the ethernet card:
model: ‘Ethernet controller’
Looking up the identification information in the PCI ID repository tells me I’m dealing with a 82801DB PRO/100 VM (LOM) Ethernet Controller
Looking at /boot/solaris/devicedb/master, I found the following similar drivers:
bash-3.00# grep 82801DB /boot/solaris/devicedb/master
pci8086,1039 pci8086,1039 net pci iprb.bef “Intel 82801DB Ethernet 82562ET/EZ PHY”
pci8086,103d pci8086,103d net pci iprb.bef “Intel 82801DB PRO/100 VE Ethernet”
Both cards use the iprb driver so I add the identifier for my driver into /etc/driver_aliases:
Load the driver with the modload command and plumb the interface:
ifconfig iprb0 plumb
If that works, create the /etc/hostname.iprb0 file. I wanted to use DHCP so I did the following:
Then do a reconfigure reboot.
Today I realized I was missing the showrev command on a Solaris 10 machine I installed.
I found it in the SUNWadmc package but recieved the following error:
ld.so.1: showrev: fatal: libadmapm.so.2: open failed: No such file or directory
Then I found the following page:
showrev(1M) missing on Solaris 8
Adding the SUNWadmfw package as mentioned still left me with the following error:
ld.so.1: showrev: fatal: libadmutil.so.2: open failed: No such file or directory
It turns out I was missing the SUNWadmlib-sysid package.
If you are missing showrev check if you have the following packages:
SUNWadmlib-sysid SUNWadmc SUNWadmfw
