Iptables -m option(s) missing [SOLVED]
Hi there, trying to block an outgoing connection by command-name but the following happens:
$ sudo iptables -A OUTPUT -m owner --cmd-owner myapp -j DROP yields
iptables v1.4.21: unknown option "--cmd-owner"
ls -l /usr/lib/modules/`uname -r`/kernel/net/netfilter |grep owner
-rw-r--r-- 1 root root 1411 Apr 8 14:11 xt_owner.ko.gz
So hmm, does that mean in our current vanilla kernel (3.19.3-3 is it?) we have some net options not set?
i.e. would I need to compile the kernel for this Or is it just a command which has disappeared into oblivion over the years?
edit: yes, the module is also loaded.
PPS. Ok, it does indeed seem to be an ancient command, that particular option.
So the question is rather.. does iptables have an equivalent matching pattern aginst a command_name?
I use/am learning nft more on some other systems but for the one in mind, uses iptables.
Well, not sure if there is a command specific solution in the venerable iptables but I solved it by using a group and be done with it.

How come the switch user option is missing from my lock screen?
I upgrade to Lion my iMac Core 2 Duo and now when I lock the screen the switch user option is missing from the lock screen, you just have to cancel o renter as the original user, so that if another member of my family wants to switch and use the mac he or she cannot do it.
This is what I am talking about (image taken from a lion review): http://dl.dropbox.com/u/134544/forum/Schermata%2007-2455766%20alle%2011.05.12.pn g
The switch user option is totaly absent, I just have the cancel.
It that a bug or what?
Please note this happens only when I lock the screen from the screensaver, i.e. requesting the password to restart from the screensaver, if I get to the login windows all users appears correctly and people can switch back and forth.
Thank you.

http://goo.gl/p6Sb0 (libri)I just talked to apple support. They said Lion doesn't support this feature. They gave me a work-around, which was to disable requiring a password in the screen saver. Then enable user switching so it appears in the top right of the banner. Note that since the screen saver no longer locks the screen, in order to actually lock the screen the user must click on the upper right user list and select something like "Login user...".
This issue has left me disappointed with apple for a few reasons. Hopefully someone at apple will take note:
1. Apple removed a useful feature.
2. Apple did not provide a response to this thread which would have been the best forum to inform users of this change. It would have saved me and apple one long phone call. -
Adobe pushed a security update to my computer and the update failed. Now the "print to PDF" option is missing from all of my programs. How do I get it back?
Version X.1.12.Thanks. That's exactly what I did, but from the Adobe help screen. It did the trick, but I'm not very happy with Adobe for messing up my system.
I appreciate your answering back. -
Place Image option is missing in Acrobat 9
I'm trying to add an image object (jpg image) into a document. Following the instructions to use Advanced Editing>Touchup Object tool, the right clicking, there are no options displayed. The option to "place image" is absent.
This previously functioned, but now it'g gone. Any help??Security Restrictions of the document are unknown.
The problem was
resolved following an Adobe "repair" procedure, then I re-created the
pdf file by printing it to pdf (the document had a few "typewriter"
objects on it). Starting again from this point, the insert image options
were present upon right click.
My guess is that if there are
typewriter objects on the document, this provides some conflict with the
advanced editing tools. IF this is the case, the "help" sections on
inserting images needs some more helpful info of this nature. Thanks for
the response.

ColdFusion Archives option is missing
Hi,
I have a CF7 Standard installed on Windows 2003 Server with
IIS 5.1. I noticed that under Packaging and Deployment menu in
Coldfusion Administrator, the only option listed is J2EE archives.
ColdFusion Archives option is missing.
Any idea as why ColdFusion Archives is missing from
Coldfusion Administrator.
Thanks,
JoeJoe, are you asking for clarification of Ian's suggestion, about removing the license key?
You do that by editing the [cf]\lib\license.properties file, where you'd remove the sn value (leave just sn=), then save and restart CF. of course, you want to copy it and put it back to revert back to that previous license when finished. (More in a moment.)
By removing the key this way,you revert CF to the Developer edition, which is the same functionality as Enterprise, but limited to localhost plus the first couple of IP addresses to hit the server (requests from other IPs beyond that are then are rejected until CF is restarted).
The only way to switch from Standard to Full Enterprise is to enter an Enterprise license key, of course. His point, though, was that for the sake of what you're doing, you could avoid that by just using the developer edition to create and then restore the archive.
As for adding the key back, you can do it either by putting it back in the license.properties file, or by using the "system information" page (click the "i" icon in the top right of the CF admin). Adding a license key there takes effect immediately, whereas again if you edit the license.properties file, you need to restart CF for it to take effect. -
hello have buy usb etxrme (64 gb) a year ago.is NTFS by default?i can't remember if i convert it from FAT 32.i have 3 questions:1)why when i formating via windows i see two options?(NTFS and exFAT) in other usb drives i see 3 options:NTFS-FAT32-exFAT.is that normal? and if isn't NTFS by default how can converted to FAT32 again?2)when i wnat to mak a safe export i can' t do it with right clik from settings window.this option is missing.i can do ti only with icon in right corner.also is that normal?3)how can attach a screenshot?
have buy usb etxrme (64 gb) a year ago.is NTFS by default?
No, if new it would have been exFAT.
why when i formating via windows i see two options?(NTFS and exFAT)
Microsoft doesn't recommend FAT32 for large drives. The cluster size is too big. 32 KB vs 8 KB. And I don't recommend NTFS for flash drive due to it's journeling overhead.
if isn't NTFS by default how can converted to FAT32 again?
Maybe a MAC machine can do it. Or some utility you download. If the files on it are important to you be sure to copy them all to your harddrive or another USB drive before you format it.
2)when i wnat to mak a safe export i can' t do it with right clik from settings window.this option is missing.i can do ti only with icon in right corner.also is that normal?
I've never heard of this option so I can't help you. What version of Windows are you using?
3)how can attach a screenshot?
You upload your image someplace then post a link to it.

"Enhancement Package Installation" option is missing for CRM 7.0/NW 7.1
Hi Expert,
I am trying to install EHP1 on CRM 7.0/NW 7.1. Following the installation guide, I updated the solution manager to SP stack 24, and use MOPZ to download the software packages. But when I create a new MOPZ transaction, there is only "Maintenance" option for the product of CRM, the "Enhancement Package Installation" option is missing. The Maintenance Optimizer works well for other products, such as Netweaver and ERP 6.0.
Can someone help me? Do I need to apply some notes?
Thanks,
MinHello,
It looks like either your company has not enrolled for the Ramp Up of CRM 7 EHP1.
If your company is indeed in the Ramp Up, please check in SCPR20 if these BC sets are activated in the listed sequence:
SOLMAN40_MOPZ_TTYP_SLMO_000
SOLMAN40_MOPZ_001
SOLMAN40_MOPZ_SP18
If one of them has no activation logs or if the date and time of the third one is earlier than the first in the list, then the Maintenance Optimizer BC sets need to be reactivated.
Best regards,

Also there seems to be no obvious way to report Office bugs. This is leaving little room for improvement. Not sure if there has been any planning on this front???
For example, [MS Outlook] using the paste options randomly misses out text, (don't use it and use the 'Paste Special...' option instead). But how do I communicate this to the Office team without knowing at least one of the team personally (which I
don't)???Hi,
Do you have this issue when pasting in other programs?
If you are pasting something into Outlook, some formats and images may get lost, especially when you choose the Paste Options as Keep Text Only.
Once you have this issue again, please try with "Keep Source Formatting". This may keep the Sour Formatting and you may not get the text lost.
If you have any feedback when using our products, I suggest you press Ctrl + Alt + 7 or Ctrl + Alt + 8 to submit it. Microsoft will always listen to users' voice and make the products better and easier to use.
