So I guess next version/update of Solaris will be released in August of 2011? Solaris 10 8/11 (update 10). Such a long wait, I was hoping to see it earlier. Wanted to play with zfs new features, especially dedupliication. Oh well, will have to wait since I cant move to either open solaris oe solaris express… 
So I upgraded my solaris server to latest kernel patch and of course it had sendmail as part of that kernel. My emails stopped flowing around. Was looking how to fix it as my home server is my default mail gateway for my email. So anyway in my sendmail config I had the following lines:
O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA
O DaemonPortOptions=Port=587, Name=MSA, M=E
so I changed them to all 0′s:
O DaemonPortOptions=Port=smtp,Addr=0.0.0.0, Name=MTA
O DaemonPortOptions=Port=587, Name=MSA, M=E
then I removed the Addr field
# SMTP daemon options
O DaemonPortOptions=Name=MTA
O DaemonPortOptions=Port=587, Name=MSA, M=E
So Sun, ups, I think I should say Oracle released Solaris 10 U7. Here are the few things what I did find whats new:

•Security Enhancement
- NAT-Traversal for IPsec Key Management Developers
- Stronger Algorithms for IPsec. Three larger Diffie-Hellman integer-modulus groups (2048-bit, 3072-bit, and 4096-bit) as well as SHA2 including sha256, sha384, and sha512? SHA-2 using HMAC.
- SunSSH With OpenSSL PKCS#11 Engine Support
•Device Management Enhancements
- x86: T-State Support for Intel Based Processors

I have solaris 10 and I have test user, I have then direcotry created as events, when I do rm -r events I get the following error:
rm: cannot determine if this is an ancestor of the current working directory events
rm -rf does not even show me anything but directory is not being removed
One of the solutions that I’ve found in my case was to change user to root even though the owner of the diretories or files is test, of try the following comand:
find . -depth -exec rmdir {} \;
Massive Sun cuts planned as IBM focuses on software trio
IBM staffers have, according to a Reg source close to the parties, been talking to Sun about its software portfolio and – unsurprisingly – they don’t like what they’ve found: It’s not making any money.
IBM’s now interested in three Sun software assets: the open-source MySQL database, Java, and Sun’s Solaris operating system.
The rest, including all that open-source work Sun’s spent years building and hyping, will succumb to that classic of big vendor lingering deaths by being, ahem, “released” to the “community”.

Some time ago there used to be UNIX magazine called Sys Admin, it was great and I did like it a lot, had lots of great articles and practical how-to’s, then it just did disapear. I did capture one of those articles which I found quite usefull in creating mysql cluster but also it has great exmple on solris 10 zones nd resource control. Hope its author will not mind, but if he does I can take it down.

Starting up opsware on solaris is not a problem and its done quite easily, now doing this on solaris 10 via smf is not that difficult either, I wish opsware did this out of the box, but still not a big deal. There used to be service called: es.opensolarisblog.org/easySMF where you could construct xml file quite easily for this. I cant find this URL to be working any longer so I wanted to make sure that I put all that stuff out what I have
First you need xml file. This is what I have that I was able to create back when that website was available:
$ cat smf_opsware.xml
<?xml version=”1.0″?>
<!DOCTYPE service_bundle SYSTEM “/usr/share/lib/xml/dtd/service_bundle.dtd.1″>
<!–
To mount /root/sparc.iso file under /mnt directory.
issue the following commands.
# lofiadm -a /root/sparc.iso /dev/lofi/1
# mount -F hsfs -o ro /dev/lofi/1 /mnt
to unmount
# umount /mnt
# lofiadm -d /dev/lofi/1
Note: lofi = loopback file driver
In the past you had real CPU’s and it was not a problem to determine what exactly you had in your SPARC system, now days with multi core and multi threaded CPU’s its more and more difficult to figure out if you have just one socket (real CPU) or multiple cores or even threads as it is on T2000 series.
Easiest way is to take a look at the following command with -pv options:
# psrinfo -pv
The physical processor has 2 virtual processors (0 16)
UltraSPARC-IV+ (portid 0 impl 0×19 ver 0×22 clock 1500 MHz)
The physical processor has 2 virtual processors (2 18)
UltraSPARC-IV+ (portid 2 impl 0×19 ver 0×22 clock 1500 MHz)
# uname -a
SunOS server1 5.10 Generic_137111-08 sun4u sparc SUNW,Sun-Fire-V490
#
# psrinfo -pv
The physical processor has 16 virtual processors (0-15)
UltraSPARC-T1 (cpuid 0 clock 1000 MHz)
# uname -a
SunOS server2 5.10 Generic_137111-08 sun4v sparc SUNW,Sun-Fire-T200
