Visit to Peking University, Beijing
Cindy organized an event at Peking University on Monday 16th April.
I gave a talk on opensolaris to Peking University students in Beijing, China. I went to the university along with two CAs(Tracy and Lucy). I met Meredith, CA from Peking Univ. and also opensource community member Zachary. The talk started exactly at 19:00hrs. I've started my discussion by showing some videos about Sun and participation age.
Later I discussed about
* Sun Academic Initiative
* Sun academic developer program
* Open source and licensing
* OpenSolaris and its features(dtrace, ZFS, SMF, zones...)
* Live CDs/Live USBs
* Hands on usage of SMF, zones and pools
30 students were attended the talk. Finally I got very good and interesting questions on ZFS, SMF and containers. Also one student asked about is opensolaris can be installed on mac OS ?
The discussion went up to 21:00hrs. I found very good talented students in Peking university, I'm sure if they get little support we can do lot better. All the attendees were aware about Linux.
Special thanks to Tracy and Lucy for their wonderful support.
Students are listening the talk very interestingly.
Showing the demonstration.

Techfest @ MIT Chennai
Our campus ambassador, Sreedhar from MIT Chennai reports about the event which they have conducted at their campus.
============================================
Carte blanche ’07 has turned out to be a huge success. I take this opportunity to share our experience.
The kind of people who visited our stall ranged from school students to
systems engineering professionals in the industry. We briefed about the
operating system concepts to school children and explained the endian
problem briefly. They were listening very keenly and appreciated our
efforts.
We had a couple of students from neighboring engineering colleges. Their
interest in solaris OS and its unique features was overwhelming. We told
them features like ZFS, Dtrace and zoning and also about the Niagara
architecture(as some of them were interested in microprocessors). As a
demo we showed how to write a Dscript and run it. We showed the
organization of probes and how the Dtrace system actually works. We also
explained about the modular architecture of the solaris kernel and the
differences between solaris and linux and the occasions were one beats
another.
It gives me immense pleasure in sharing some of the feedbacks we recvd
for our demo.
- I m a system admin in a leading organization. I feel this is excellent
information on solaris features.
- Wonderful lecture about advantages of open solaris.
- The demo was informative.
- Very informative and clear explanation.
- Cool to hear that you are using solaris(this was by a linux geek).
In addition to this several college students were eager to know how we
could make it up to learn solaris. We then explained them about SAI and
we gave them the link to join it as well. They were very much satisfied
by the advantages of SAI and have promised to talk with their faculty
and getting involved in the program. We also had a couple of people who
needed information on sun training and certification. As the information
pamphlet was remaining with me, I could explain the different programs
.We also distributed a pamphlet to a student who was very interested.
Finally to sum up our stall was a real crowd puller and had a great
response from the visitors. I feel proud to share about this rocking OS
with people and I wish that people in my college appreciate it truly and
use it extensively.

FOSS.in 2006 conference is being held from Nov 24th to 26th 2006 in Indian Institue of Science(JN Tata Auditorium), Bangalore, one of the premier institute in India. BangLinux was its original name, from last year onwards this has been renamed to FOSS - Free Open Source Software. Sun being platinum sponsor this year too and we had great FOSS event last time. This time also under the leadership of Sumitha, Joe and couple of others lead from the front and prepared lots of things.
Day 1
We are showing the following cool demos
- Virtualization on OpenSolaris
This includes zones, branded zones, xen, qemu
- ZFS
- Sun Grid
- FMA - Fault Management Agent
- Looking glass, Belenix(LiveCD OpenSolaris distro from IEC)
- Glassfish
- OpenJDK, portal server and so on
Lots of BOF sessions are lined up, first day we had couple of dTrace BOF sessions.
Handouts being distributed on the Sun technologies. Also there is a quiz contest being
organized by Ananth. quiz contest
Lots of interest in the student, developer communities. Pleople used to ask questions related to how do I contribute? Can I get a help if I'm stuck? Students ask on how about projects ?. There is whole lot of enthusiasm across the community.
NAL(National Aerospace Laboratories), one of the premier organization in Bangalore, India. One of the executive from NAL came to the booth and asking about solaris and its technologies. He was more interested to know about virtulization. During our discussion it turned out to be replacing all his boxes by solaris which solvs his lots of problems. Totally he was very excited and told me that he is bringing some other persons from NAL tomorrow to know more about our technologies. We need to tap this market as well as there is lots of growth and potential in such premier organizations.
Thats it. more is coming later. Stay tuned.

inetadm -e <FMRI> Attempt to enable a given inetd based service
inetadm -d <FMRI> Disable a given inetd based service
Configuration Commands
======================
svccfg(1M), svcprop(1) and inetadm(1M)
The svccfg command is used for manipulating data in the repository (properties,
snapshots, etc) and uses sub-commands to perform the various actions. Some
common sub-commands are:
select <FMRI> Select a service or instance to work on
list Show the children of a selected service
listprop List the properties for a given service or
service instance
setprop <property> = <value> Assign a new value to a given property
delete <FMRI> Delete a service from the repository. Avoid
deleting instances unless you really need to as
this can cause problems when reimporting a
manifest
validate <manifest.xml> Validate a manifest before importing into the
repository. See also xmllint(1)
import <manifest.xml> Import a service manifest into the repository
unselect Navigate to the parent selection, eg: from the
instance back to the service
listsnap List the snapshots for a given service instance
selectsnap Select a snapshot at the instance level
revert [<snapshot>] Revert the service instance to a selected
snapshot
The svcprop command is used to display information about a service from the
repository. There are various options to this command, for example:
svcprop -p <property> <FMRI> Show the values for a given property, eg: $ svcprop
-p start smtp:sendmail
svcprop -s <snapshot> <FMRI> Show the details from a given snapshot
The inetadm command when used with the -m option modifies a property for a given
inetd based service instance. An example of this is:
# inetadm -m svc:/network/ftp:default exec="/usr/sbin/in.ftpd -a -l"

SMF troubleshooting techniques
Logfiles, Manifests and Methods
===============================
SMF logfiles can be found in the following locations:
/var/svc/log
/etc/svc/volatile
The SMF manifests and methods may be found here:
/var/svc/manifest/*
/lib/svc/method/*
To see the log file location for a given service use:
$ svcs -l <FMRI> | grep logfile
(<FMRI> - Fault Management Resource Identifier. See the svcs(1) manual page for
details of how to specify an FMRI)
Daemons, Configuration and Recovery
===================================
The primary daemons for SMF are svc.startd and svc.configd. At boot time the
kernel will start init, which in turn starts svc.startd and that starts
svc.configd. This latter daemon (svc.configd) will read information from the
repository in /etc/svc/repository.db which is then used by svc.startd to start
the services.
If there is a problem booting the system you should try:
ok boot -m milestone=none
Then try to reach milestone "single-user" by running:
# svcadm milestone svc:/milestone/single-user:default
Observe the services as they start, look at any messages on screen and consult
the error logs for more information. If the repository is corrupt you may need
to restore from a previous saved copy, or reseed it.
The /lib/svc/bin/restore_repository script will guide you through this process.
=================================================
If a service fails to start, you should check:
* The state of the service instance
- If a service is in maintenance mode use:
svcs -xv or svcs -l to see why it failed
inspect the log files for further information
svcadm clear <FMRI> once the fault has been repaired
* The dependencies for the service
- Are they optional or required?
svcs -d shows the dependencies for a service
svcs -l shows whether the dependencies are optional or required
* The error log for the instance
svcs -l <FMRI> | grep logfile tells you where the logfile is
* The properties for the service
svcprop -p start <FMRI> shows the start properties for a service
* Have any changes been made to the repository?
- How many services are affected?
- Have any snapshots been created?
- Can you resort to a previous snapshot?
* The start method for the service
- What type of service is it? (transient, child, contract)
- Look at the start method
- Did the service get killed? Why?
- Check the start method in the manifest and compare it to the repository
entry
- If you need to truss the service starting, you could try something like:
# svcprop -p start/exec network/inetd ! Use to figure out start method
# svccfg -s network/inetd setprop 'start/exec = “truss -f -a -o
/tmp/truss.out
/usr/lib/inet/inetd %m”' ! Use the method obtained from svcprop
# svcadm refresh network/inetd
# svcadm restart network/inetd
Remember to restore the original start method when finished!
======================================================
If there are problems booting the system, you should:
* Capture the error message(s)
* Try to boot to an alternative milestone, eg:
ok boot -m milestone=none
ok boot -s
* If successful and you can login, try to start the next milestone
* Check the error logs and dependencies
* Can you boot the system in verbose mode, eg:
ok boot -m verbose
NOTE: This changes the boot behaviour from parallel to serial
* If the repository is beyond repair, try restoring from an earlier copy
or in the worst case you may need to reseed it.
The utility for this is /lib/svc/bin/restore_repository

SNMP in Solaris
SNMP in Solaris
Solaris has a rich set of products that support SNMP protocol.
Some of these products are part of Solaris and others can be installed on top of Solaris
* System Management Agent(SMA) * Solstice Enterprise Agent(SEA) * Sun Management Center(SunMC) * Solstice Enterprise Manager(SEM) * Mobile IP agent * Platform specific SNMP agents such as Netra agent, Enchilida, JDMK agent and so on Background SNMP is widely used in enterprise networks to effectively manage systems, network devices, and networks. One of the benefits of SNMP is that solutions can be quickly created to support the increasing numbers of networking components and applications. Within SNMP networks, systems, components, and applications are described as entities. The number of entities that need to be managed is growing rapidly.
SNMP uses a manager and agent architecture. The SNMP manager is a program, also known as a network management station (NMS), that runs on a host on the network. The manager sends requests to one or more SNMP agents running on devices connected to the network. An agent, or daemon, is a program that listens for SNMP requests from the manager.
Agent hierarchy consists of a master agent and subagents. The master agent receives the SNMP-based management requests from the managers. The master agent sends responses to these management requests. Responses are sent after retrieving the appropriate values from respective subagents.
Subagents provide management of different components. Management is based on a Management Information Base (MIB) specifically designed for components or applications. A MIB is a specification containing definitions of management information. Through the use of a MIB: networks and networked systems can be remotely monitored, remotely configured, and remotely controlled.
An agent receives a request and looks up information in the MIB and returns information to the manager. Each object in the MIB represents a piece of data about the managed device, and each object is assigned a unique identifier in the MIB. The manager and agent must have access to the same MIB to be able to communicate about the managed device. The manager uses the MIB to specify identifiers for the information that the agent is to act upon. The agent uses the MIB to look up the identifiers that were passed in the SNMP request from the manager. The agent gets or sets values for the requested data.
The System Management Agent is designed to be a standalone agent. That means the SMA agent can run without having any external NMS to run, but can work with any external NMS using SNMP protocol. The SMA can be accessed by multiple management applications, provided that these management applications communicate with the SMA using SNMP protocols. The SMA can coexist with existing SNMP agents. The SMA replaces some legacy SNMP agents.
The SMA is a new SNMP agent offering from Sun, based on the Net-SNMP open source implementation and is available from solaris 10 onwards. This open source implementation is described at http://www.net-snmp.org/. This open source implementation was formerly known as UCD-SNMP. The System Management Agent is designed to support the latest SNMP standards.
In this Solaris release, the System Management Agent can co-exist with the Solstice Enterprise AgentsTM software. For more information about the Solstice Enterprise Agents software, see the Solstice Enterprise Agents 1.0 User Guide. From an SNMP manager view, the System Management Agent operates in the same way the Solstice Enterprise Agents software. Unlike the Solstice Enterprise Agents software, the System Management Agent supports SNMPv3. The System Management Agent supports more default MIBs than the Solstice Enterprise Agents software. Please refer user and developer guides from http://docs.sun.com
Sun contributions to open source in SNMP world are
IPv6 support
64 bit binaries
Security best practices code enhancements
PKCS support
Documentation enhancements
Large number of bug fixes
SNMP traps
SNMP traps are often used by network devices to report conditions. Trap information will "automatically" go out when the condition for the trap is met.
For instance, if you have multiple network links and you lose one then the "linkDown" trap will go out to inform the Network Management Station (NMS) that your machine has lost a link. All you need to do is define the host names of any NMS that you wish to send traps to. The following piece of code will be generated for TRAP-TYPE variables such as demoEntryString and demoEntryInteger in table column by using mibcodegen(mib compiler). This is fixed as part of 4519879 struct CallbackItem genCallItem[13]={ {(Object *)&column_table[1],STRING,1}, {(Object *)&column_table[2],INTEGER,2}, {&object_table[2],OBJID,-1}, }; int genNumCallItem=3; int genTrapTableMap[11]={ 0,}; int genNumTrapElem = 1; struct TrapHndlCxt genTrapBucket[11] = { {"demotrap1",1,6,1}, }; struct TrapAnyEnterpriseInfo genTrapAnyEnterpriseInfo[11]={ {1, 3, 6, 1, 4, 1, 42, (uint32_t)-1}, }; struct _CallTrapIndx { char name[256]; IndexType *pindex_obj; }; struct _Indx { char name[256]; int index; }; int numIndxElem = 2; struct _Indx Indx[2] = { {"demoEntryString", 0}, {"demoEntryInteger", 0}, }; int SSASetVarIndx(char* name, int index) { int i; if (!name) return (-1); for (i = 0; i < numIndxElem; i++) if (!strcmp(name, Indx[i].name)) { Indx[i].index = index; return (0); } return (-1); } IndexType TrapIndx[3] = { {1,1,&Indx[0].index}, {1,1,&Indx[1].index}, {0,0,NULL}, }; struct _CallTrapIndx CallTrapIndx[1] = { {"demotrap1",&TrapIndx[0]}, }; int SSASendTrap(char* name) { int i; if (!name) return (-1); numCallItem = genNumCallItem; numTrapElem = genNumTrapElem; callItem = genCallItem; trapTableMap = genTrapTableMap; trapBucket = genTrapBucket; trapAnyEnterpriseInfo = genTrapAnyEnterpriseInfo; for (i = 0; i < numTrapElem; i++) if (!strcmp(name, CallTrapIndx[i].name)) return (_SSASendTrap4(name, CallTrapIndx[i].pindex_obj)); return (-1); } In order to make snmdpx handle Traps from subagents during startup, the trap-port for communication between a subagent and snmpdx should be distinguished by using the function SSAGetTrapPort() from the SEA sdk/API. mibiisa mib-II subagent sends traps to snmpdx by send_traps(). send_traps() calls send_a_trap() per manager.
