Hosts-update: automatically append the mvp blocklist to /etc/hosts

This util written by wintervenom has actually been in the AUR for going on 2 years now.
What it does:
Updates /etc/hosts with the mvps blocklist to prevent thousands of parasites, hijackers and unwanted adware/spyware/privacy websites from working.
Operation is trivial:
1) Edit /etc/hosts.local to match the hostname of your system and adjust the domainname as needed. Also add any hosts that you wish to keep i.e. other PCs on your network.
2) Run /usr/bin/update_hosts as root which will append /etc/hosts.local to the mvps blocklist and apply some post processing writing the final file to /etc/hosts automatically.
3) (Optional) Add a cronjob under root crontab at some interval to keep your /etc/hosts fresh.

Sure you can, but not in this particular tool. There is a script written by haarp designed to run on a tomato-usb powered router that does just this. I host the code here: https://github.com/graysky2/adblock
EDIT: I can't remember if it pulls from the same urls as pgl does but you can certainly modify the code to do it.

Appending a blocklist to /etc/hosts

Is it possible to append a blocklist (er... redirectlist) to /etc/hosts somehow?
For example, mvps has been supplying a very nice list of known parasite websites for years. Basically, it just uses 127.0.0.1 to redirect known bad websites so they don't load. It's a nice system-wide method to block them. I have been pasting their list into my /etc/hosts but am wondering if I can someone call it as I do in bash scripts.
For example, this doesn't work, but you get idea:
$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost novelty
192.168.1.1 router
192.168.1.2 inky
192.168.1.3 blinky
. /etc/hostsmvps # try to load the mvps redirect list

Thanks for the script, I actually wrote one very similar to yours but then thought I'd ask about sourcing it like a bash script does...

Update automatically about the data warehousing

I have done data warehousing using owb, but what way or how can we let the cube update automatically when the original tables changed? thank you

You'll need to building mappings to load your source data to your cubes and then one option is to schedule these to run via a process flow and scheduled job.
Search the Net for 'Oracle OWB by example' for some tutorials.

I've had my HTC Rhyme for about 4 months and it updated automatically to the software that was right before Google Play. When I try to update to Google Play, it says there's no service, but there is. What should I do?

Hello!
No Play Store, sounds like no fun! Let's get this fixed! I would recommend trying the store in safe mode first. If that doesn't work a hard reset would be the next step. Here are the steps for both:

Please assist, my notebook updates automatically with the latest version of firefox, which was done, thereafter i am having problems when i open the firefox

My notebook is set to update Firefox automatically which it did last night. Since the update, when i open the Firefox browser, it opens up several tabs after the home page. I am also unable to copy of the page, when i do try it opens up the very same page in another tab. Also i am experiencing problems with my Microsoft office programs, since the Firefox update was done. I am unable to open documents within the programs, when i do click to open a new document or try to open an old document, it automatically closes the program. My operating system is Windows 7 home Basic, 32-bit operating system.
Please help, thank you.

If you don't usually get a choice of where to save a downloaded file, you can change that using:
Edit > Preferences > General > "Always ask me where to save files"
Then you may want to go directly to the source:
http://www.mozilla.com/firefox/
You should get the options to Save File or Cancel (not Open). Hopefully after saving you will be able to find the downloaded file in the location you specified.
One other note, before upgrading, you may want to back up your Firefox settings just in case. [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information].

There is a problem with the mail updating automatically in the toolbar at the top of the page ! my seeting s are correct. i did not have this problem with early versions!! not good,

firefox wont update the mailbox to inform you you have new mail.
preivious version was ok.
all settings are correct .
tried starting new and still the same

Sorry, that "mail" thing isn't a standard part of Firefox. Seek support from the developer of the add-on you have installed that added that feature to Firefox. Support contact information should be on the download page for that extension.

Should the loopback alias in /etc/hosts be localhost?

This was something I ran across recently when installing NTP...for some reason, if I change the loopback alias to my actual machine name, the command <code>ntpq -p</code> would not work...it would reply: Name or service not known. However, leaving the alias as localhost and trying the command again works just fine.
The reason I had altered it initially was due to Xfce giving me a warning dialog box upon startup that says it cannot find the host. Changing my loopback line to
127.0.0.1 localhost.localdomain servername
instead of the default...
127.0.0.1 localhost.localdomain localhost
eliminated that error message and Xfce would start up with no problems. I vaguely remember reading somewhere that it should be left at localhost and not be set to your actual machine name, but I don't remember the reasoning behind it. Do I really have to choose one error or the other? Any thoughts?

Ahhh...never knew you could do that. I'll give that a shot once I get home and let you know if it worked. Thanks Mr. Prickly!

What is the original file /private/etc/hosts ?

Trying to understand I made a bad edit !
Thanks !

To set it back, it should read like this. At least, this is the content on my Mac.
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1             localhost
255.255.255.255 broadcasthost
::1                      localhost
fe80::1%lo0        localhost
Don't know if it would make a difference, but the first and fourth sentences ending with "localhost" use a tab character for the space between 127.0.0.1 and fe80::1%lo0. The second and third lines are padded out with space characters.

Update manager in IdM automatically when the manager changes in SAP HR

Hi Experts
I have been given a requirement where the manager of a user in IdM should be updated automatically when the manager changes in SAP HR.
The HR extraction job is currently in place and runs every 30mins.
Please could you give me some ideas on how to implement this.
IDM 7.2 SP 6
Thanks
Ran

Hi Deepak
I have been discussing this a bit more in detail with the client. So, the issue is as follows
When a new/replacement manager is hired
When people are moved from one org unit to another
The scheduled extraction job (RPLDAP_EXTRACT_IDM with a variant with the delta tick on) does not update the new manager info in IDM for the relevant users who report to that manager. The client has to run the program (RPLDAP_EXTRACT_IDM with a variant with the delta tick off) manually each time for the affected users which updates the manager info successfully in idm.
I investigated the query LDAP_IDM_QUERY from user group /SAPQUERY/L1 and want to know if the below should be ticked as well. Your thoughts please?
Please advise.
Thanks

RG1 is not Updating Automatically

Dear All Salute !!
RG1 is not updating automatically in the system due to data migration on cutoff date since February; they are maintaining parallel in the legacy system (in Excel or any other), though here is updated project from 5.0 to 6.0.
I am unable to understand, how the system is going on in the lacking of this.
From Accounts Department side: Still Cenvat duty posting & statement (57AE) are done manually by dispatch/stores department. As per ECC6, system generated report should be available to the end users to avoid duplicate work & mistake.
As per observation from SD side _no Opening Balance is uploaded while data migration_.
I have got information through SDN about table J_2IRG1BAL but I am unaware of using this.
Please provide me complete solution for this to do the needful instead of OSS Notes.

Adding to Komals reply,
Please go through the sap note 951955 and check below comments:
Please check whether you have maintained opening balances for
all RG1 material in table J_2IRG1BAL. If not, please maintain opening
balances for all RG1 material in J_2IRG1BAL for the date from which
you want to run the RG1 report.

Check for itunes updates automatically

Hi I'd like to roll itunes 7.02 out to my business users as we intend to deliver work related content via podcasts, but I'd like to standardise on a version.
Is there anyway to uncheck the "check for itunes updates automatically" in the general preferences via the registry?
I have looked can can't locate this setting but it must be there somewhere.
Thanks in advance

You have Synergy running? What happens when you don't have it running?
Any utility, whether a widget, an application or whatever, that controls or gets status from iTunes has the potential to launch iTunes when you don't expect. The developers try to ensure it doesn't happen but it can still happen.

Will Flash player update automatically? I have that box checked.

I have a Mac Book Air 13" 2011 running Lion 10.7.5
I checked the Automatic Update Flash Player box in the Flash in System preferences.
Will it update automatically 30 days after the new Flash update 11.800etc.
I read on the internet that if you check that box it will update automatically in the background.

Mendel 1
I appreciate your trying to help, but I was under the impression that it would update without going to their website.
When I click on download and install it opens Safari and takes me to their website.
The last time all I had to do was go to systems preference, click on Flash and in a few clicks it did it automatically without ay trouble at all.
I didn't have to open a disc image or anything it seemed to do it automatically in the background.
I read that if you check the update automatically in the Flash Preferences it would cotinue to do this seamless update.
I also read that after 30 days after the new update, it would do it automatically, (if you hadn't done it from the website.)
Is that not the case anymore?

In the command line how do I find the etc/host file? is there one?

I am trying to work remotely and use our lotus notes system (which is from a windows based server) but I have to connect to the mail server and our IT person wants to find the equivalent of the Windows host file or host table . is there such a file? we went here
http://linux.die.net/man/5/hosts
hosts(5) - Linux man page
Name
hosts - The static table lookup for host names
Synopsis
/etc/hosts
thanks

Since you're using a Macintosh, quit reviewing linux stuff. These, when entered in the Terminal app (inside /Applications/Utilities/) should point you in the right direction:
*cat /etc/hosts*
details in:
*man hosts*
FWIW, you should search the Unix forum (or post your query there) under OS X Technologies.
