Update files always downloaded via HTTP

Hi,
We have enabled SSL on our WSUS server and all clients are now reporting back successfully via the default SSL port 8531. Some clients go though a site firewall so we have enabled 8531 only. These clients are detecting updates but failing to download them,
the site firewall is logging lots of denied attempts on port 8530. Is this as expected? In which case I will allow port 8530 as well but I was expecting all traffic to be via SSL 8531.
Many thanks, Andrew

In which case I will allow port 8530 as well but I was expecting all traffic to be via SSL 8531.
If you were expecting all traffic to be via SSL, then you've probably also misconfigured the WSUS server itself. While opening the port will certainly be required, removing SSL requirements from the appropriate v-dirs will also be required.
The correct configuration for using SSL with WSUS is documented in the WSUS Deployment Guide:

Retrieve online file as CSV via HTTPS using PL/SQL procedure

Hi all,
Situation:
Server A (not ORACLE)_: accesed via URL, generates dynamically a CSV file and returns to the requestor.
Server B (ORACLE)_: which runs the PL/SQL script. It is the requestor. Read the CSV and store it within ORACLE.
(1) I want to connect from Server B (ORACLE) to an external URL via HTTPS which generates dynamically the CSV file. Subdomain.domain it is the Server A which contains this CSV file.
https://dubdomain.domain/csv_generator.php?query=q1
(2) This file is downloaded to the Server B (ORACLE). A PL/SQL script executed in this machine do the task.
(3) After that, I load this CSV to an ORACLE table which a common CSV PL/SQL parser.
Doubts:
Is it possible to retrieve an online file (a CSV) dynamically created and hosted in a third party server (Not ORACLE) via HTTPS using a PL/SQL procedure executed in a ORACLE server? If the answer is yes, what technology could I use? Any ideas?
Thanks in advance,
Yago

An CSV example in {message:id=10158148}.
For https, two actions are needed in addition.
Firstly, the certificate of the https web server needs to be loaded in an Oracle Wallet on your database server. The wallet will have a specific directory location on the server, and will be protected by a password.
Secondly, the PL/SQL procedure making web call, needs to open the wallet (using <i>UTL_HTTP.set_wallet</i>) using the location and password. Example of that in {message:id=10820182}.

I can't get the entire update file to download, 995mb then stops.

995mb then stops. I can't get the entire file to download and this is a fast connection, says 23 minutes to download the file, but stops short. I have tried about 15 times over the last 7 hours, yet it always stops at 995mb.
I've tried over wireless and wired, and wired is very fast, as I mentioned, it shows only 23 minutes to download the entire 5.3gb file. but it never gets that far. I'd wonder if we have a data cap on the network (work), but it allows me to download the same 995mb over and over.
if anyone has experienced this, I'd like to know what you did to get it to download. thanks

Downloading Mavericks requires a high speed broandband connection.
Check your download speed here > Speedtest.net - The Global Broadband Speed Test
Anything less than 15Mbps is too slow to download the 5GB file which may why it's timing out at 995Mbps.
You may need to contact your ISP for upgrade options.

Files always download as "attachment.ashx" instead of the file name and file type that they actually are.

Since I have installed the new version of Firefox (version 8.0), every single file I download is downloaded as "attachment.ashx" and won't open. I have to change the name as well as the file type in order to open the document.
This happens regardless of if I'm downloading from email, from a website, etc.. All of the files I have downloaded also have already been named and had file types appended, but Firefox is changing them every single time. I have never had this problem before using the same sites and downloads.

Please hurry up with a solution! This is causing havoc, as I cannot open any attachments at all! It defaults to Adobe Photoshop, and then I get an error message that it is the wrong type of file. These are all Word docs! I can't get my work done! Is there some kind of work around that I can use in the meantime to open these things?

My couldn't save the software update which is downloaded via WIFI

when downloading there is no problem but after a few hours the download is failling due to some corrupted filet but the system says yhat it would check the problem once updated again and when retrying the update the same problem is occuring

Uploading large files using nio in http client

Hi,
I'm developing a multithreaded Swing client which needs to be capable of uploading and downloading large ( 100mb ) files to servlets via http.
Downloading has presented no problem, but writing to the OutputStream of a URLConnection, whilst fine for small files, gave me 'out of memory' errors on large ones. ( As I understand it, the whole stream is buffered before sending and it just runs out of room.)
So I replaced the URLConnection with a SocketChannel, and after writing the http header, used a loop to write chunks of data from a FileChannel.
I needed to monitor any incoming data to truncate the upload if the servlet gives a premature response indicating an error condition, so I set the SocketChannel to non-blocking and put a read into the loop.
Immediately I got a bunch of Swing exceptions and the frame was unable to render itself, I guess due to thread starvation problems.
I currently have this clunky code that seems to work ok:
int percent=0;
long total = 0L;
long chunk = 1024*8;
while(total<length ){
chunk = ((length-total)<chunk)?length-total:chunk;
long ii= fc.transferTo(total,chunk,socketChannel);
total+=ii;
yield();
socketChannel.configureBlocking(false);
if(socketChannel.read(buffer)>0 )break;
socketChannel.configureBlocking(true);
What I can't figure out is why Swing objects if I permanently set the SocketChannel to non-blocking rather than just whilst I read it, and why I get the following exception from a polling thread that runs concurrently:
'No buffer space available (maximum connections reached?)'
Anyone got any ideas or a better way to do it?
Chris

I assume that the OutputStream obtained fromURLConnection is internally buffered and URLConnection
waits until the whole stream has been input before
inserting the initial Content-length header. Only when
it knows the complete length is the content sent. Hmm, this is quite unfortunate. Especially since it is not necessary: HTTP allows the data stream close to serve as the end-of-data marker (Content-Length: is an optional header, in its absence the receiver simply reads all of the data until the sender closes the stream).
Has anyone else had experience of sending large
(100mb) files through Java http clients on small
pc's?I've sent large-ish (~1-10Mb) payloads via URLConnection but not as large as yours. Interesting issue to figure out... I am out of ideas for the moment.

3.11 update file is corrupt - cannot extract

For a few days now I have been unable to update my copy of
Contribute because the update file I download is corrupted every
time. I've tried both the 3.1 & 3.11 update zip files, two
computers (work & home), and two web browsers (Firefox &
IE). At home I tried using WinRAR instead of the WindowsXP's zip
file support and that gave me this error: "C:\Documents and
Settings\sean\Desktop\contribute_3_11_updater.zip: CRC failed in
Contribute_3.11_Installer.exe. The file is corrupt".
Can someone help me? Is there another site with these files
to download?
Thanks

See the further information area of Troubleshooting issues with iTunes for Windows updates for direct download links and obtain a fresh copy of the installer. Disable Norton's real time scanner during the download/update if necessary.

Thanks for the update Phil. I would have never remembered that, which I think is obvious at this point.
I remember that situation well. An iOS update file, automatically downloaded to MANY iOS devices without the user's permission & no easy way (aside from actually installing it) to remove it to regain the storage space (multiple GBs) that was stolen. It's still a sore spot to me...

NAC appliance(security policy/update-files)

Does anyone know something concerning to the following issues?
Please teach me what I can refer to on the WEB,if possible.
1. Is there any way to apply the policy(checking OS/AV) to the kind of client devices which CAA hadn't been installed such like guest user?
2. Is it possible that NAC appliance does clients only "port-scanning" (not checking OS/AV)?
3. If user-company already has their own "Anti-Virus Server" or "Windows-update Server", can CAM refer to their servers(not Cisco's policy-update-server) to get current update files?
4. How long does it take the update-files become available via Cisco's policy-update-server after each OS/AV-vender had released them?
Regards

No, we should install Cisco Trust agent S/W in order to collect the information about the OS versions, AV versions etc to the Policy server. And based on the security policy of the organisation, we can communicate with the AV vendors like symmntac, Mcafee servers directly for the latest patches and updates.

Problem downloading a file via http

Hi
I'm just getting started with WLS (sp5) and am having a problem downloading
a file via http. The document is stored in the main html docs directory and
whenever I link to it or try to download it directly (eg:
http://<host>:<port>/myfile.doc) I get the following error in a message box:
Your current security settings do not allow this file to be downloaded.
Can anyone point me in the right direction as to where I grant permissions
to do this - I've tried using the weblogic.security.URLAclFile and adding
the directory as a weblogic.io.fileSystem (a desperation move, I know).
Thanks in advance,
Peter Villiers

PLEASE IGNORE THIS POST
The problem was caused by someone (me though I honestly don't remember doing
it), setting the content security level to high in my web browser which
stopped this type of download.

To where are Software Updater file downloaded?

I have a software package to update on two computers. The computers are the same and I need to update software on both computers. However, where I live we pay for each megabyte downloaded so I would like to update the first computer then copy the update file to the other. Where does the Software updater store the downloaded files so I can get the file after the first computer is updated?

I have updated my iphone 5 with IOS7. Now there is an update 7.0.2 on my cell and the size of update file is showing around 21.0 MB. I tried to update it ITunes but it seems it is downloading the entire IOS. Is there any separate update for the same or I have to download the entire IOS again?

Well when you download the update with iTunes it will always download the whole new version (in your case 7.0.2) even if its just an bug fix. If you already have 7.0 download the update over-the-air.
You already wrote that the update is only 21 MB, so its not the whole firmware package of 7.0.2 you get with iTunes.

Update files always downloaded via HTTP
