Block clients from internet

Our school is running OSX on a G4 with about 21 computers and as teachers we share the network with different grade users. Is there a way we can block the internet from others users, the other grades are giving the password to the internet and it upsets the atmosphere of the room when the other teacher is teaching. We are using workgroup manager.
G4 Mac OS X (10.4)

WRT54GL (192.168.10.0/24, NAT, DHCP)==========LAN (192.168.1.0/24, gateway 192.168.1.1+other computers)...
If the WRT54GL is 192.168.10.x and your LAN is 192.168.1.1, then computer's connecting to the WRT54GL will not access the resources/computer's connected to the 192.168.1.1(LAN) Network as they are running different individual networks...

Block clients from individual wlan

I have 5508 with 2 WLANS (corp, guest) I would like to be able to block certain users via MAC address from CORP but not guest.
Can this be done.
CORP is using WPA2+AES
GUEST is using Web Auth ( guest is not setup as a "guest vlan" in the config, just a regular wlan.
TIA

Hello,
Like Viren said mac-address filtering is not the most secure way as they can be easily spoofed.
Why don't you try Peer-to-peer blocking.
Peer-to-peer blocking is applied to individual WLANs, and each client inherits the peer-to-peer blocking setting of the WLAN to which it is associated. Peer-to-Peer enables you to have more control over how traffic is directed. For example, you can choose to have traffic bridged locally within the controller, dropped by the controller, or forwarded to the upstream VLAN.
For more on this you can ckeck the following short cisco doc:
http://www.cisco.com/en/US/docs/wireless/controller/7.4/configuration/guides/wlan/config_wlan_chapter_01010.html

BB10 cant block apps from internet access in Application Permissions?

I have a Q10. BB 10.1 OS.
It appears I cant prevent third party apps from gaining access to the internet among other settings under the Securities/Application Permissions. This is in huge contrast to my 9700 where I can very specifically dictate what program has access to, whether that be Wifi, Data, Bluetooth etc.
Is there another way to do this or is this OS not complete yet and these functions will be included back in future iterations? Or is my OS a dated version?
This is problematic for me. Seems this problem presents as both a security issue in cases where the third party app has mal-intensions, as well as being a data leech should the program constantly utilize data unbeknownst to the user.
Internet is just one thing. What about the camera, mic etc? How do we know ID thieves are not making BB10 disguised as something useful so they can data mine the users and send all of their personal information back to them via unfettered internet access, mic access, camera access, GPS location access (hence know home + work addresses) and then perform criminal activities using your data?
Im shocked. I thought Blackberry is supposed to be better in the security department compared to Apple. THis is what I expected from Apple and Android. Or is this the new thing? All third party apps purposefully get internet access whether the user agrees or not?

Great question. Unfortunately I don't have an answer, but can comment that these preloaded apps are using MB from my datapak that I paid money to have for MY personal use! Not theirs! I believe it's theft when they use what we pay for. Time to check legalities in my opinion.

But don't work. I also tried to add the pptp and gre in the outside access rules but nothing...
I don't understand why if a connect directly to the outside interface with the same outside network works well.
ej: the pc have 89.120.145.14 ip and the outside asa have 89.120.145.140 and if I create one vpn in this pc the outside ip 89.120.145.140 with the correct parameters the asa don't discart 1723 and connect ok but if this ip is not of this range discards 1723...

Block users from downloading from internet

I'm curious as to what everyone is using to block users from downloading certain file types (.exe, msi, zip, bat, etc) from the internet? We had websense, now barracuda for a web filter but have major issues with filtering downloads from the internet. The main issues is filtering SSL sites.

Hello,
The WSA has a feature called Object Filtering which allows admin's to configure access policy parameters to block certain file types from being downloaded through the WSA. To apply the same settings to HTTPS requests the WSA would need to decrypt the request.
I Hope this helps.

Error message from Internet Explorer v8.0.6

My Muse test site is currently on Business Catalyst. The url is http://wfax-test.businesscatalyst.com — my client says that they get an error message from Internet Explorer version 8.0.6 "MuseJSAssert: error calling selector function: error: a security problem occurred". The good news is that this only appears on the "Schedule" page of the site. Any idea what it could be? My client is afraid for me to put the site online because of this error message.

Hi Artby,
In your page, you have a link to "http://[email protected]//[email protected]" (Saturday Afternoon at 3:00). This link is technically a valid link, but I'm not sure it is what you intended. If you where looking to create an email there, you should remove the http:// in front of the link and Muse should properly create an email link. If you were trying to go to a website, I'd recommend you check the URL again to make sure you have it right.
The link is throwing a security error because we have to do some extra processing for some of our links, so we check each of the urls and try to determine if there is extra logic we need. In this case, this link is telling the browser you'd like to "login" to the site qemi.org with the username "apostle". IE 8, by default, will block us from reading information from this type of link in case there is a password, or in case we shouldn't know the username. It is a security measure (thus the error) and should pose no risk.
If you did intend to have that URL, then this won't quite work at the moment in Muse. To work around this, you could pull out this small snippet into a custom HTML element or something, which Muse won't try and process (though you'd need to remove the class "nonblock" from the link if you copy/pasted the Muse export code).
Hope that helps,
Andrew

How do I block pings from the outside to the ASA 5505 outside interface?

I was asked to block pings from the internet to the outside interface of our ASA-5505 firewall. I found a post that said to enter "icmp deny any outside", however that does not do it.
I created an ACL to try and do the trick, also to no avail:
access-list outside_in extended permit icmp any any echo-reply
access-list outside_in in interface outside
access-group outside_in in interface outside
Anyone have a clue what I'm doing wrong? I'm not the firewall guy as you can tell. :/
Thanks in advance...
Block / Deny ICMP Echo (Ping) on Cisco ASA Outside Interface
Most networks that you protect with a Cisco ASA device, will probably want to deny ICMP (maybe not all ICMP types, but a lot of network admins will want to block ICMP Echo, etc.) on the outside interface. This will make the network harder to find through external enumeration, but not impossible.
ASA5505(config)#icmp deny any outside
You will deny ICMP on the outside interface, but if you include ICMP as a protocol in the default global policy map, you can ping from the inside to any host on the outside, and it will be permitted back through the ASA, as it knows about the previous ICMP “connection

You are allowing echo-reply, thus it will reply to a ping
try this ACL:
icmp deny any echo-reply outside

How to restrict users working on Windows 7 clients from accessing Windows Explorer and other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2

Dear All,
We are having an infrastructure setup of around 500 client computers managed through group policy.
Recently the domain controllers have been migrated from Windows Server 2003 to Server 2008 R2.
Since this account requires extremely strict environment, we need to figure the solution for restricting the users from access anything locally.
It would be great if you can assist me with the following query.
How to restrict users logged on Windows 7 clients from accessing Windows Explorer and browsing other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2 ?
Can we disable Network Tab on the left hand pane ?
explorer.exe is blocked already, but users are able to enter the Windows Explorer by clicking on the name which is visible on the Start Menu.

>   * explorer.exe is blocked already, but users are able to enter the

You cannot block explorer.exe when you do not replace the shell - the
desktop you see effectively IS explorer.exe...
Your requirement sounds like you need a custom shell:

Unable to list SFTP Directory on windows 2008 r2 server from internet

Hi experts,
I have configured a SFTP on windows 2008 r2 server. And i am using the Filezilla on client machine to connect to SFTP server.
The connection works properly on internal network but it displays error when i connect from internet.
Error: GnuTLS error -53: Error in the push function.
Response: 550 Data channel timed out.
Error: Failed to retrieve directory listing
This machine is publish with public IP and port22. The connection and authorization process gets complete but stops are Directory Listing.
PLease suggest the troublshooting steps..
Let me know if any more info is rquired.

Hi,
Do you also use the Filezilla to configure SFTP server? Since you use Filezilla on client machine to connect to SFTP server, I would suggest you ask for help from Filezilla forums for better and accurate answer.

How do i block website from my macbook pro

how do i block website from my macbook pro?

It's an very old and simple question! There are two ways that you can use to block websites on your Macbook Pro:
1. Enable the Parental Control on your Macbook Pro, choose the app you don't want your kids to use.
2. Install the Internet filter software for Mac that can help you block any unwanted websites automatically.

RDP from internet not working in Hyper-v VMs

Hello .
Sorry for my english .I hope to explain clearly my problem .
I 've Hyper-v on Windows 2008 server r2 . I've 3 Virtual networks ( External , Private and internal ) .
In my VMs there are two domains . The first one is bound with internal Vn and the second is bound with private Vn. My Host RRAS is configured to switch inbound connection RDP (3389) to a second RRAS (Virtual machine bound with private network) . Last
RRAS does port forwarding correctly to the machine for RDP connection ( port 3389) request .
RDP works only from host and VMs but not from internet in private vn.
RDP from internet connects but when try to configure session disconnects . Any ideas ?
Netstat says "SYN-RECEIVED" then disconnects .
All other services work fine (http mapped between RRAS host and RRAS vm i) and RDP works in private virtual network from internet . I think the problem is nat over nat for port 3389 in internet connection . I've tried to disable firewall but
not works .
Thanks

Also add firewall exception "from" any or specific ip "inbound" "to" whichever destination.
To truly test, you ca disable firewall, if it allows rdp session, then you know it is something with firewall.
Remember sometimes antivirus software includes firewall., and in the case of home routers, they have built-in firewall, and Windows also has firewall, so you must be sure to check ALL possible locations of firewall blocking and dropping (even server-to-server).
Basically you would be allowing inbound from your router, NATted through (or routed through) your network, to the destination or allowing inbound from server to server. Also
double check that your server NICs are not having any additional 2nd DHCP interfaces, if so, disable the secondary DHCP NIC and test again. And do:
traceroute
From Internet to the server having the issue and from server to server and it may uncover more details of where things are getting dropped.
I have heard also some ISPs may also try to block inbound RDP or 3389, so be sure and verify that as well.
Please mark as answer if I helped solve your issue. Thank you.

Calling SAP GUI Client from a Java Webdynpro app.

Hello experts,
We would like to call the SAP GUI client from a java WebDynpro application running without portal or ITS. Can it be done by having a web link, with mime registration in internet explorer to kick off the SAP GUI ? (similar behavior with a SAP favorite link saved on the desktop).
many Thanks.

Hi,
Webdynpro possibilities:
1. You can try to use LinkToUrl.
with reference to file://<exefile> or your weblink with the mime type (possibly some java coding can be required; I can try to help).
2. other option is to use IFrame and you can use either href to your exe or weblink
Web Explorers:
1. IE: It should work. if you point to exe file popup window will be displayed asking for action (run, save, cance).
2. Firefox: the only way I know to make it work is to modify nsHelperAppDlg.js file (if you need Firefox I can tell you how to modify the file).
Kind Regards, Jack
