The entire concept of making code freely accessible for others to view, use and even modify would appear to clash totally with the commercial software strategy of SAP AG. So why is the world's largest vendor of business software so interested in open source?
That was a question being silently mumbled by a few software experts in the coffee breaks at the Open Source Forum backed by Hasso Plattner, SAP's billionaire co-founder.
And the answers gleaned from a few of these experts were two-fold: open source is a threat to proprietary software; but it's also an opportunity.
SAP needs to keep abreast of what the open-source community is doing because the open community approach to developing software will play a huge role in the future and will impact proprietary software, according to Adam Jollans, open-source software strategy manager at IBM Corp.
"SAP must be prepared for the next big technology, and that could be open-source software," Jollans said. "IT is changing very fast. Big players like SAP can be beaten by companies with new ideas. SAP knows this."
But it's not only open-source startups that the Walldorf, Germany, vendor needs to have on its radar screen; it's also arch-rival Oracle Corp., according to Don Wight, vice president of worldwide field operations at open-source business intelligence software vendor JasperSoft Corp.
"SAP has to be wondering what Oracle is planning in the open-source space, especially after its recent acquisition of Sleepycat," he said. "Even if Sleepycat isn't a big fish, it's certainly part of a larger strategy."
Where open source stands on SAP's priority list remains anyone's guess, but it is on that list and appears to be inching upwards.
"There is certainly a trend in the open-source space, and we're investing," said Jai Das, a partner in SAP Ventures, the company's venture capital arm, which is in Palo Alto, California.
SAP Ventures has already invested in several open-source companies including MySQL AB, Black Duck Software Inc. and Zend Technologies Ltd., as well as social communications and wiki company Socialtext Inc.
But where open source fits into SAP's long-term strategy is a well-kept secret, and understandably so.
For a company that generates billions of dollars in revenue by marrying customers to its commercial software, a move to open its code and let the open-source community peak inside and even offer some of its code for free would certainly raise a few eyebrows among investors.

1 DHCP server for the entire network - more than 1 VLAN
This made for sharing of the Windows administrator(2k / 2k3) who want to implement a DHCP server to 1 serve some of VLAN (Virtual LAN) is in the work place.
As we know, VLAN implemented many reasons for sharing security and performance reasons for the network. If a network too large, it is usually the network will be slowed, particularly if we use file sharing.
VLAN is usually used to separate the network based on department / network specific ... so, for example, Department marketing in some of the floor, they can still connect to the 1 network (VLAN) are the same. However, if we want to use the VLAN
to separate the network between the floor / inter-building, so may, of course, welcome.
In general there are 2 steps works that must be done to do this:
1. Make settings on the dhcp server
2. Make settings on the managed switch multilayer
After these two steps, then the DHCP server that has been made, can be used for the entire network.
Let's see the example below:
For example, in the place where we have 4 VLAN:
VLAN 1 network is 192.168.0.0/22 -> VLAN for switch management / router / server
VLAN 2 network is 192.168.1.0/22 -> 1 for all building ...
VLAN 3 network is 192.168.2.0/22 -> Building for 2 ...
VLAN 4 network is 192.168.3.0/22 -> Building for 3 ...
Overall this is assumed VLAN is already running well routingnya
DHCP server (Server A) has the address 192.168.0.50 placed in VLAN 1, along with all other server ..
IP Address for the computer so the client:
VLAN 2, the client computer's IP is 192.168.1.1 to 192.168.1.255,
VLAN 3, the client computer's IP is 192.168.2.1 to 192.168.2.255,
VLAN 4, a client computer's IP is 192.168.3.1 to 192.168.3.255,
Now, let's do the first step:
SET DHCP SERVER
------------
Stages in the DHCP Server A
1. Add a DHCP server roles in Windows Server 2000/2003 through the Configure Your Server,
2. Go to the DHCP console in the Administrative Tools.
3. Create some appropriate VLAN DHCP scope ..
Right-click on the DHCP Server, -> New Scope
Name scope, for example, DHCP Building 1,
Fill in Start IP Address: 192.168.1.1; End IP Address: 192.168.1.254
Setting the DNS, Wins Server, Router / Default Gateway, etc.
For DNS, and Wins server can still fill in the DNS IP on a different VLAN.
To Router / Default Gateway, fill in the appropriate VLAN with its own
Activate the scope.
Repeat the second step, the scope for other ..
If you are finished, will have some scope in the DHCP Server Console
4. The last step, Authorize DHCP Server DHCP Server to enable this
... ... ... Up to here, step 1 is is complete ...
SET SWITCH MULTILAYERNYA
-------------------
1. VLAN check it .. including the gateway / ip VLAN that routing is running ..
2. Log in to each VLAN, and VLAN configurations in order to get the DHCP from the DHCP Server A.
If the Cisco switch, the command can be used
"Ip helper-address xxxx" -> this command to notify that the DHCP server for VLAN is xxxx
In the example above means ... command ip helper-address 192.168.0.1 ..
3. If you are ... check configuration, and save.
You have successfully created 1 DHCP server to handle the existing network in your workplace.
Congratulations & Good Luck to try!
