Aironet 1231G basic config question

Hi, we have an Aironet 1231G with IOS 12.3(8) and we have enabled DHCP service with two VLANs, one for management (VLAN1) and another one (VLAN 2) for user IP addressing. We do everything by the config guide book (subinterfaces on both dot11 and FastEthernet etc.) however we want DHCP enabled server on AP to allocate IP addresses to clients on VLAN 2 once requested.
We have noticed that all is fine if we want AP to allocate IPs on management VLAN 1, it does not work when we try to do it for VLAN 2; however we want different VLAN for management and different VLAN for users.
We have also tried on sub-int F0.2 to configure an IP address with no success though since DHCP does NOT allocate IP addresses on VLAN 2, is there some sort of config trick that we are missing or is it something that can not be done on AP? Please note that we have it working with DHCP server enabled on a router and connected via sub-int to AP, in this case air interface dot11 allocates succesfully IP addressing for user VLAN 2.
Any ideas, any help will be really appreciated,
Thanks a lot
Tony

change the dhcp scope and the interface vlan2 ip addressing it will allocate an address in a new range.

Cisco Aironet 1250 basic setup questions

Hi,
I'm going to be three Aironet 1250's within a building. There is not going to be a wireless controller, the AP's are all going to be standalone. I am going to set them all up the same, with WPA2 wireless encryption. My question is, is it important/beneficial to add configuration to the AP's so they are aware of each other (for roaming perhaps)? If so, what is this technology called and could someone point me towards a section of a guide that could illustrate this?
Or am I good with just configuring 3 standalone AP's as is.
Any other pointers are welcome.
Thanks!

Hi,
On Autonomous APs you can use Wireless Domain Services (WDS) technology which allows the APs to be aware of each other and make roaming faster withouth needing full authentication each time the clients move from one AP to the other.
Basically you configure the same SSIDs on all 3 APs, then only one will act as primary WDS.
The primary WDS will be responsible for the communication between the clients and the RADIUS server, and the infrastructure APs will simply bypass all the info from the clients to the primary WDS and vice-versa.
Evenually you can configure standby WDS with different priorities so that in case of the primary WDS goes down, another AP assumes the role of active WDS.
Configuration Example via AP GUI:
http://www.cisco.com/en/US/products/hw/wireless/ps458/products_configuration_example09186a008059a559.shtml.
In attach you can find an example of config using WDS and Infra APs. You will find example to configure open ssid, psk, and eap using WPA2.
3 diferent vlans.
Clients authenticate against External RADIUS Server and APs authenticate on local RADIUS for WDS.

Aironet 1231G for home use

Hi all
I've been given an Aironet 1231G that I would like to set up for home use. Has anyone got any example configs for this type of setup that I could take a look at? Nothing too complicated is needed, just something simple and secure.
Thanks

A few post config questions on new setup

Hi Group,
Just a few post config questions.
First, how can I confirm my controller is in fact associating properly with an NTP server? On a typically cisco product, I could just do a 'show ntp associations' or a 'show ntp status'. I cannot see a way to confirm this on the gui or command line.
Second, on my guest network with web-auth, if one were to choose to not use https for web-auth and instead use unsecure http, would that be possible and if so where in the gui?
Thanks.

The third field is from a WLC running v7.4 not v7.2. I usually would install a 3rd party certificate, but what eles you can try is issue this command on from the CLI. It had issues working with certain code versions, but you might as well give it a try.

Basic iPhoto questions:

I have some Basic iPhoto questions before I start using the program:
- does iPhoto apply any compression or change images in any way when they
are imported?
- after images are imported, can the original source folder of images be deleted off of the mac?
- can Quicktime files exported from iPhoto be viewed on a Windows computer?
- can iPhoto handle large resolution images that might be as large as 8-15mb each? does it display them quick? are there any known file size issues?
Thanks!!!!

kat.
Is there a way to use iPhoto on a network so other users can read and possibly write to an iPhoto library on a networked mac?
iPhoto is a consumer level photo organiser, not a server. It's possible to share photos but libraries are very difficult and fraught with the danger of database corruption. Some have reported success.
Is it possible to password protect or secure certain images in the library so they can not be seen by anyone?
No. The best I can suggest there is to create a second library and store it in a secure area like a protected dmg. But remember, you can only have one library open at a time.
After photos are deleted from iPhoto, are there any remaining traces or cached files anywhere other than the trash
If you delete photos from iPhoto and empty the iPhoto trash then the pics are removed from the Finder as well. They remain as findable as any other deleted file from that point, which is, very, if the searcher in knowledgeable.

Object class deployment - Basic form question

OK, I subclass calendar object from Oracle provided standard
object class. What do I need to deploy to use this form now
apart from calendar.pll and my fmx. What about the object class
from which I sub-class. Do I need to compile and deploy that
also? How will form resolve this on run time the parent object
class as I really did not copy, just sub class and we do not
deploy original class? Basic form question. Thanks.

You can set the "help" property on the field (which gives you the little "information" icon link beside the field).
You could also try adding another field of another class above or below:
<Display class='InlineAlert'/>
<Display class='ErrorMessage'/>
<Display class='HtmlPage'/>

Workshop Weblogic config questions

I'm using Oracle Workshop for WebLogic 10.3 and I'm hoping someone can answer some setup/config questions.
When I double click on the server (WebLogic Server v10.3 at localhost) a window opens with various settings that manage how workshop and weblogic work together.
Under "Startup & Deployment" I have the following turned on:
Launch WebLogic server in Eclipse console
Always start WebLogic Server in debug mode
Ignore project compilation errors when publishing (I have this turned on because of errors in a portal project, the errors aren't inmportant, and don't prevent the project form running)
Run stand-alone web module directly from workspace
So, first question, with these settings I was able to quickly switch to debug mode, with out restarting the server, now the server restarts whenever I turn debugging on. What have I done that has stopped this working correctly? How can I get it to start debugging without a full restart?
next question, what happens if I turn on "Start WebLogic Server in Express Mode"? As far as I can tell nothing happens.
Lastly, under "Automatic Publishing" I have it set to "Never publish automatically", if I choose another setting workshop essentially freezes because it's constantly publishing. So whenever I make a change, even in a jsp, I need to remove the project, then re-add it to see my changes in the browser. This is frustrating, not just because it takes 8 or 9 minutes (8 or 9 MINUTES!!!), but because the project doesn't run properly until it is redeployed. You'd think that if it needs to be re-deployed, then none of my changes should matter on the server until it is re-deployed.
So, my question is, Is there any way to get this re-deployment to happen faster?
Thanks for any and all help

Well, in my experience performance is not bad as you experienced. Is it locally connected server or remotely connected server? If it is a remote server, network issue could cause this latency issue.
Is performance better if you run the server without enabling debug mode? If yes, probably you can also review any break points set.
You could also try out the following options
1) Run workshop with -clean option, by opening command prompt and navigating to workshop_home\'workshop.exe -clean'
2) Untick the option 'Launch WebLogic server in Eclipse console' and start server which would enable server to start on command prompt
3) This would enable you to take multiple thread dumps (cutl +Break) on the server console output, while performance is very bad, to see where threads are halt.

Re: PLM4P v6003 Config Question: Any way to configure UGM Notifications?

After reading:
PLM4P v6003 Config Question: Any way to configure UGM Notifications?
This is one of the requirements from me as well. We always wanted to customize emails sent not only for UGM but also for other modules. We wanted to conveysome message to approvers. But it seems this is still not possible. Is this functionality on road-map of AgielP4P product management?

Currently, the subject and body of emails can be customized to an extent, as they are translations that can be overridden. The translations have some placeholder fields that get populated by the system, but you are limited to those placeholder fields. The upcoming release will give you full control of the email body and subject lines, for GSM and SCRM emails, as well as Supplier Rep emails.

Redundant FWSM Config Question

Hello All,
I'm going to be configuring failover with FWSMs for our 6500 at my job and I have a config question. There is one current 6500 chassis with 2 FWSMs installed. They are both online but currently since failover isn't setup, only one FWSM is actually active. My question is since we are using mutiple contexts where do I setup the failover interface, and do I need to configure failover on every single vlan on the FWSM? We have over 10 contexts each with 2-3 interfaces on them, so do I need a failover IP for every vlan that exists on every context? Also, does the failover config get setup on the admin or system context? Any help would be greatly appreciated, and thank you so much in advance!

Hi John.
Failover config goes in the system context. For the data interfaces in each context, you will need a primary and a standby IP i.e. 2 IP's per VLAN. Once failover happens, the secondary FWSM will assume the active role and the secondary FWSM will take over the Primary IP address thus making the failover process transparent to end users.
HTH.

Adding Date/Time Field + X Number of Days - Basic Calculation Question

I am assuming this is a basic calculation question. New to Adobe LiveCycle Forms.
I have a simple form containing a table. The table appears as such:
Text
Formatted as Date/Time Fields
Header 3
Monday
user wil choose the beginning date (Date/Time) this is DateTimeField1
Tuesday
this should calculate DateTimeField1 + 1
Wednesday
this should calculate DateTimeField1 + 2
Thursday
this should calculate DateTimeField1 + 3
Friday
this should calculate DateTimeField1 + 4
Saturday
this should calculate DateTimeField1 + 5
Sunday
this should calculate DateTimeField1 + 6
Calculations are performed after the date is chosen for Monday. My mind tells me the simple calculation of DateTimeField1 + 1 is not going to work (and in fact doesn't!) as it needs to change Monday to a number first. I saw on another thread the following:
Num2Date(Date2Num(Date(DateTimeField1), "DD.MM.YYYY")+7, "DD.MM.YYYY")
Thought this was going to get me close. No cigars though!
Any quick help is greatly appreciated. And since I am new to this, details about what needs to be changed would be great too!
Thanks

Here an addition for you date field.
This FormCalc script in the exit:Event will check it the selected date is on a monday.
If not it will go the days back until the last monday.
var Selection = Date2Num($.formattedValue, DateFmt(2))
var WeekDay = Num2Date(Selection, "E")
var NewDate
if (WeekDay eq 1) then
          NewDate = Selection - 6
elseif (WeekDay eq 3) then
          NewDate = Selection - 1
elseif (WeekDay eq 4) then
          NewDate = Selection - 2
elseif (WeekDay eq 5) then
          NewDate = Selection - 3
elseif (WeekDay eq 6) then
          NewDate = Selection - 4
elseif (WeekDay eq 7) then
          NewDate = Selection - 5
else
          NewDate = Selection
endif
$ = Num2Date(NewDate, "EEE DD.MM.YYYY")
Hope this helps, too.

SCCM 2012 application portal: config questions

Hi,
We have setup SCCM 2012 application portal correctly and it's working fine.
However some config questions:
-can we change the name of the configuration portal? Now its servername/CMApplicationCatalog ... what's not userfriendly.
We'd like it to be applicationportal.ourcompany.com. Howto achieve that?
-can we customize layout in a supported way (we could change html pages but after an upgrade of SCCM they would/could be erased)?
-how does flexera (adminstudio?) plugs in into this. I've read this entry
http://helpnet.installshield.com/appportal2014/Content/helplibrary/AP_CreatingCatItemSCCM.htm but what's the big picture here? Anybody using this? What are the advantages?
J.
Jan Hoedt

We want to offer software center for overview of mandatory installs, application catalog for optional software.
On our companies portal, we can then set a link which directs to the application portal. User can then install optional software from there.
My current config works http://applicationportal.ourcompany.com/ goes to the sccm-server but not to the url below.
That would be http://applicationportal.ourcompany.com/CMApplicationCatalog/#/SoftwareLibrary/AppListPageView.xaml
how can I make sure the application portal shows up when this link is opened?
It sounds like you want to perform a URL rewrite?
http://www.iis.net/learn/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module
You should test this to see if it's what you want - I may have misunderstood your question.
Also, I wouldn't host this module on your AppCatalog server, I'd host the rewrite module elsewhere.

Basic Exporting Question

My main question is a very basic exporting question, but here is a super-condensed explanation of my big-picture goal for context:
Large (~450 MB) aiff on CD --> trim w/ Quicktime --> small (~16 MB) MP3 in iTunes
I would like to take an audio file (aiff) that is approximately 450 MB and export it from Quicktime and in doing so, reduce the file size and convert it to MP3. When I simply try to export it, it doesn't ask me about what size I want, nor does it give the option of MP3 formatting.
I have figured out how to reach my goal, but it's a mess. After I make my trims in QT, I have to:
1. select "share" instead of "export".
2. It asks me what size I want and I select small.
3. The file is then exported as a Quicktime movie into Mail and the size is reduced from 450 MB to about 20 MB.
4. I then have to "right-click" on the attachment in the email that is created,
5. save the attachment,
6. discard the email,
7. import the file into iTunes, and
8. create an MP3 in iTunes to finally arrive at my goal.
This seems like a ridiculously convoluted process to change a large aiff to a small MP3 and put it in iTunes. Any suggestions?

Thanks. I guess the basic answer to my question is that it can't be done in one or two fell swoops. The problem is that it starts on a burned disc, and I need to make edits to it before it ends up in iTunes (to be eventually used in iWeb). I was hoping to avoid juggling back and forth between iTunes and QT. I either would have to send it back to QT to do the edits after -->iTunes-->mp3, or import the large file from the CD to QT, make the edits, save changes, import large file to iTunes, convert to mp3.

Basic N1 SSH config questions...

At the risk of asking remedial questions, are these actions correct?: 
<li> When generating SSH keys, I am to generate one set with the ID used to install/owner of the MS (agent, server, cli)? (i cant remember now if cli installed w/ the master seerver or not, i think it did)</li>
<li> I am to create a second user and generate keys, and place this users pub key into the authorized_keys2 file of the first user (product install/owner of MS) </li>
<li>How do I tell N1 about the existance of this second user? Is this what pe.defaultUserToRunAs is for? I cannot find this in the docs. </li>
<li> According to previous postings, root ssh'ing is required for OSP. This makes no sense to me when the agent can be owned by a non-root user, yet can execute native commands with root priv.</li>
<li>The docs state that SSH forwarding works downstream, but can it use loop back to the master server?</li>
<li>Why do I see the product use a root shell to CLI back to the Master server (OSP question)? Should this be happening?</li>
Thanks for everyones help.

At the risk of asking remedial questions, are these
actions correct?: 
<li> When generating SSH keys, I am to generate one
set with the ID used to install/owner of the MS
(agent, server, cli)? (i cant remember now if cli
installed w/ the master seerver or not, i think it
did)</li>True for MS/LD/RA as they always run with the same uid. CLI works best, if always invoked as the install owner. If the CLI is invoked as any other user, then there are couple options,
one is to make sure that each user has their ssh keys configured so that the connection from their machine to the MS machine with their ssh credential succeeds.
Another is to configure CLI to always a single identity to connect to the MS. For security reasons, you may want this identity to be different from the MS install owner. If you look at the ssh man page, it allows you to override the default uid and identity file locations through options -l & -i.
Lets say we create a new user spsuser, for CLI authentication.
We can then generate ssh keys for spsuser and put them in this identity file, lets say /home/spsuser/ssh/identity.
We can then configure sps CLI to override the ssh credentials that are used when connecting to the MS as
net.client.parms.1=sshargs=-o|BatchMode yes|-l|spsuser|-i|/home/spsuser/identityThat way CLI will always try to use the same ssh identity regardless of who invokes it. However, since I haven't tested this configuration, I'm not certain if it will work. The one possible issue here is that ssh may complain about the identity file having global read permissions.
>
<li> I am to create a second user and generate keys,
and place this users pub key into the
authorized_keys2 file of the first user (product
install/owner of MS) </li>Nope, the keys always belong to the same user, unless you are overriding the default user to the first user when running ssh as the second user.
>
<li>How do I tell N1 about the existance of this
second user? Is this what pe.defaultUserToRunAs is
for? I cannot find this in the docs. </li>I think you are talking about the CLI here. In this case you'll be running the CLI as the second user, right? In that case all you need to do is to make sure that the second user is able to connect to the MS machine from the CLI machine using ssh, without requiring any user interaction.
>
<li> According to previous postings, root ssh'ing is
required for OSP. This makes no sense to me when the
agent can be owned by a non-root user, yet can
execute native commands with root priv.</li>The ability to run native commands as root is only available when the agent is running as root. Otherwise the plan that tries to run exec native as root will fail if the agent that its running on is not running as root.
>
<li>The docs state that SSH forwarding works
downstream, but can it use loop back to the master
server?</li>Not sure I understand the question. downstream here implies from the machine invoking ssh client to the machine thats running the ssh daemon. I don't think ssh would care if the the ssh daemon was connected to via any IP address or loopback...
>
<li>Why do I see the product use a root shell to CLI
back to the Master server (OSP question)? Should
this be happening?</li>My opinion is that CLI doesn't need to run as root for most of its functionality. The only case where it may need to run as root is when the files that its trying to checkin are only readable by root. However, it may make sense make those file readable by the CLI user instead of running CLI as root in that case. Don't know if it makes sense to have OSP run the CLI as a non-root user instead..

Basic struts config question

Hi,
What does the "input" attribute of the struts-config.xml do?
Thanks

Check out the [url http://struts.apache.org/dtds/struts-config_1_2.dtd]struts-config dtd[ur;]. It documents each of the attributes/tags you can use in the xml file.
     input           Module-relative path of the action or other resource to
                     which control should be returned if a validation error is
                     encountered. Valid only when "name" is specified. Required
                     if "name" is specified and the input bean returns
                     validation errors. Optional if "name" is specified and the
                     input bean does not return validation errors.Simply put, it specifes the jsp page to return control to when validation fails - ie return you to the input screen, display errors and let you correct them.

Basic flashback config question

I have an Oracle database (10.2.0.4.0 on Linux) installation that I have inherited. A user deleted some data and I attempted to recover it. There were backups and archive log files in the FRA, but when I queried about flashback status I got:
select flashback_on from v$database;
FLASHBACK_ON
NO
1 row selected (0.06 seconds)With that config set to "no" that means I can not use flashback to recover lost data. It must be set to yes before the failure occurs in order to use flashback to recover afterwards. Do I have that right?

If your retention is not enough big, however you disabled FLASHBACK, you cant get it.
But there is a big procedure, if it is really critical, if your database is running in archivelog mode, Restore database in any test server, recover database before deleting rows, Take an export of the table and import into this database.
