Secure way to obtain host address

I'm doing a simple RMI project that guarantees a secure communication between a server and client residing on different computers.
So, for communication, I thought of using RMISocketFactory, with an SSLSocket.
My problem resides in obtaining the host address, I don't want it hard-coded in my program.
What secure ways do I have for obtaining an host address?
Encrypt in a text file and read from it?
Regards, Nuno.

Encrypt in a text file and read from it?Yes, but only if a person has to provide the password to decrypt the file every time the program starts. Otherwise, you have to hardcode the password in the app, and if you're going to do that, you might as well just hardcode the password.
Another alternative would be to put the address in a plain text file, but make that file readable only by the user id that runs the app.
It's impossible to know whether any particular solution is viable for you however, without knowing the details of your requirements and constraints.

SQL Cluster - Unable to obtain IP Address from System Center IP Pool

Hi everyone,
we are trying to deploy a SQL cluster into a windows azure pack tenant cloud.
Our azure pack environment contains:
- 4X Hyper-V server in a failover cluster
- 1X SCVMM server
- multiple WAP server
Steps we have done:
-   Windows failover cluster is installed and configured successfully
-   Quorum disk was configured successfully
-   SQL server 2014 installation (via static IP) is successfully. But routing between the VMs is not possible.
-   SQL server 2014 installation (via DHCP) fails at the end of the installation with following error:
       -> We used DHCP to obtain an IP from the scvmm IP pool.

Hi Darryl,
thanks for your supply.
We don't have an DHCP in the Cloud. System Center DHCP is used for assigning IP addresses and routing inforamtion to the vms.
This works fine for assigning IP addresses to the vms.
At my current point of understanding network virtualisation with system Center, we do not have an alternative to this way of assigning IP addresses.
Kind Regards

Obtain MAC Address from 250 iPads

Hi all,
I have taken delivery of 250 iPads which I am configuring with OSX Server on a MAC Mini. So far, so good!
Our wireless network uses MAC Address authentication so I have to add each MAC Address to our Cisco Wireless controller.
Without having to go to Settings > General > About and write down the MAC Address from every device, is there a way to obtain the MAC Address from either the box using the barcode, or maybe an App that loads up on screen and shows the MAC Address of the device in a barcode format that I can then quickly scan into an Excel spreadsheet and import?
I feel that i'm about to waste a lot of time going on to each iPad and obtaining the MAC Address
Thanks in advance
Regards
Jim

If you have the ability to plug them into Apple Configurator, you can connect them with a USB hub and update and supervise them. This will let you export MAC Addresses and Serial numbers from Configurator to a CSV file that you can use to upload to your wireless controller. If you need to, be sure to Unsupervise the iPads when you are done.
The info you're looking for may also be available through GSX, but I'm not familiar with everything you can use it for on your end.

Obtain bad address bge0

Hi
i was changing the ip address, gateway and dns of a sun solaris 9 machine. i have edited the files hosts, resolv and defaultrouter elsewhere. however, i forgot to copy the edited hosts file over and reboot the system. i thus obtained bad address bge0 and when ifconfig -a , it shows inet 0.0.0.0. have used terminal to get in and managed to use vi to create a file and mv to replace the hosts file. (hosts file is read only under vi). after reboot, inet still is 0.0.0.0. Have then use ifconfig command to change it and it manages to change to the required ip address. But the problem lies here, after reboot, the inet jumps back to 0.0.0.0 although the hosts file is correct now..
any one knows a solution to this? please..
thanks

You also needed to edit /etc/hostname.bg0 in order to set an hostname. Also; just because a file is marked 'readonly' in vi doesn't mean you can't edit it. If you have the proper permissions (root) you can force vi to save your changes regardless of the lacking w permission flag using !.

Problem: The wireless client Obtaining IP address.

Problem: The wireless client Obtaining IP address.
Setup.
I have a fiber circuit which feedes my Wan port. Then
I made a local network that then I branch off to five other AirPort Extremes.
Acting as access points with a static IP for local network, with no security enable and extending the wireless network name is off.
With both types of models, the new & older all extreme models.
Sym:
I can reset the head end airport router with will fix the problem for a day or so.
Question:Can the wireless client cause this type of problem. the reason I asked, everything was working fine for the last 2 two years until I added a new access point. I have change it out with another unit which did not help the dhcp problem.
So my thinking either my head end router is starting to go bad with DHCP or a wireless client interaction may be locking up DHCP until I restart the router again.
Has any one had the same type of problems with DHCP???

Thanks for the quick response.
The first option sounds like I need some type of wireless software which at the moment I'm not utilizing so don't know how to do that.
option 2 also sounds foreign to me ! ;-)
Can you add some details or point me to any links you can ref me to so I can try to familiarize myself with these options ?

After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it.

The page load progress bar that was on the lower right of the window is no longer there. After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it. The tab has a circular progress wheel but this is useless for determining a stuck or slow loading page.
PLEASE NOTE: I am typing this in from a Windows based work computer but am asking about my Apple MacBook Pro that i use at home.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Another possibility is to use:
* [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

Assuming you have these accounts set up in Mail, open preferences and under Accounts tab, edit the SMTP outgoing server list. Do you have a .mac address in the list? If so, delete it.
Are you using iCloud?
For the troubled account, select the correct SMTP server for that account in the box and check the box to use only that server with that account.

Is there some way to add multiple addresses to an email I am sending that doesn't close the contact list after I click on an address? This necessitates constantly going back to click the + sign to add each address separately.

Is there some way to add multiple addresses to an email I am sending that doesn't close the contact list after I click on an address? This necessitates constantly going back to click the + sign to add each address separately. Is there some way I can open the contact list, click on all of the individual addresses to which I want to send the email without the list closing between each address entry, and have all of my address entries be listed to the email at one time? Something like it works in Gmail. I do not want to use set lists, I want to enter different addresses each time I send an email. And I am a very slow typist, so I don't want to type the first few letters of each recipient's name. It is much faster for me to just click on the e-mail addresses in the list as a group. It doesn't make any sense to me to have to reopen the contact list for each address, when it should be so easy to click on all of the addresses I want at one time and then click once to add them all to the email as a group. If there is a solution to this, please tell me. Thanks.

Vatlily,
Try this:
1. Select Mail>File>New Message.
2. Select Mail>Window>Address Panel.
3. Use (command+click) on the desired addressees in the Address Panel to create the list.
4. Click "To:" on the top left of the Address Panel.
The group that you selected will be added to the "To" field in your New Message.

Is there a way to change the addresses used in an existing iMessage thread?

This is kind of a multi-part question. Let me describe my scenario.
I have many iMessage threads with other iPhone users where the "reply" addresses for one or both ends are the phone *numbers* instead of AppleID email addresses. (This could be due to a number of factors... either they had their "Start new conversations from" address set to their phone number, and/or they started a new conversation with me sending it to my phone number. How it *got* that way doesn't really matter). I want to be able to change the addresses of the conversation to AppleID's (so that I'll still get messages when I change SIM cards, among other reasons).
With iOS 8's new ability to add/remove people from conversations, I thought I would be able to add the AppleID address and remove the phone number address, but there are two problems with that: 1) iOS 8 seems to only allow this for conversations which began as multi-person conversations, and 2) it doesn't seem to want to let you add addresses for people who are already recipients via another address (in other words, if Alice is already on the conversation via her phone number, I can't add her AppleID to the conversation). I guess I could remove the person first, and then re-add them with the other address... but I'd feel safer if I could add the next one before removing the first one.
I know I could just tell the other person to delete our thread and start a new one, but I don't want to lose all of our dialogue and pictures (and I don't want to have to manually save it).
So, the questions:
Is there a way to change the address my counterparty is sending to when they make further replies to our conversation?
Is there a way to change the address I send to when I make further replies to the conversation?
Is there a way to change the default address to use when trying to send someone an iMessage? (What I'm after here is a way to craft my "contact" entry in people's phones so that, when they try to send a message to me and start typing my name, my preferred address comes up on top).
As it looks like the only way to do this might be to use iOS 8's method of adding/removing recipients, is there a way of converting a two-person conversation into a multi-person one?

I think I may have solved it, actually. I find that if I switch the timecode to NDF in the source viewer, it seems to work. I have tried it on three clips and they have sync'd without problems. Hopefully this will continue to be the case.

HP LJ8000n unable to obtain IP address

We have an old LaserJet 8000n that is unable to obtain an IP address. It has been working for the last 10 or so years. In the last two weeks or so, the printer is unable to get an IP address. I did a cold reset and nothing happens. The printer is setup to use DHCP to obtain IP address. I did also tried putting the IP address in manually but that does not work either. Below is the JetDirect configuration page printout.
Any help/suggestion is much appreciated.

This seems to be a commercial product. For the best chance at finding a solution I would suggest posting in the forum for HP Business Support!

Entry for host name is missing or empty (Secure Store key: admin/host/).

Hi All,
I am in the process of installing EP7 on SLES9 and MaxDB 7.6 on a clustered HA environment where the SCS, DB and JC components are installed under and referenced by their virtual hostname (eg. sapinst SAPINST_USE_HOSTNAME <virt name>).
The SCS instance is installed, the Database Instance is installed and I'm currently in the process of Installing the JC and Deploying the EP packages.
During the installation, SDM is put into standalone mode and sapinst tries to deploy the package EPBC06_0.SCA where it fails and the sdm_server.err shows :

The same problem occurs if I try to deploy this package or any other package using SDM in standalone or integrated mode.
configtool -> Secure Store -> admin/host/<SID> is the virtual hostname of the JC instance.
I've tried the following to no avail:
- Changed configtool -> Secure Store -> admin/host/<SID> to be the physical hostname of the box.
- Changed configtool -> Server -> Dispatcher -> Service -> P4 -> bindhost (from 0.0.0.0 to JC virt IP).
- Changed the <Host> entry in sdmrepository.sdc from <phys hostname> to <jc virt hostname>.
The SAPLOCALHOST, SAPGLOBALHOST all seem to be set correctly in the SAP profiles.
Has anyone had this issue? If so, what do I need to check/change? Any ideas?
Notice the message does not reference the <SID> in "admin/host", could this be related to the issue? If so, what can cause this?
TIA
Anthony

Hi All,
Just an update, I was able to get around my problems by patching the 2004s media from sp6 to sp8, uninstalling my scs, and database and re-installing from the patched media.

Is there a way to obtain the text item's value when the mouse pointer at?

Hi,
Is there a way to obtain the text item's value when the mouse pointer at? Mouse pointer may be located somewhere out of current record and even out of current block.

There is a when-mouse-over trigger and that works fine in client-server mode for Forms 5/6/6i, but that is less indicated when deployed using Application Server.
In that trigger you may write whatever code is necessary, restricted package procedures.
Still, I think, for your case, if you do not have to deal with a multi-record block, you should use the HINT property for that item and set_item_property with the HINT argument for that item in order to set the hint to the item's value - this should set_item_property should be called on the when-new-record-instance .
