How to block a single port 1841

Hi,
I need to block a single port on my wan side fa0/1 .. my telnet port 23 as it is open and im not going to use it and want to close it ?
thank you

This example shows how to allow telnet from an internal network, ssh from any but deny anyone else while logging all activity
ip access-list extended TerminalAccess
permit tcp host 10.0.0.2 any eq telnet log
permit tcp any any eq 22 log
deny tcp any any log
line vty 0 4
access-class TerminalAccess in
You could also use the line "transport input none"
The best option is to have some secure means to remotely manage the device.

WLC - How to block a single client MAC address?

Hi Sir,
On a WLC (software version 4.1.185.0), how to block a single client MAC address?
I thought of using the SECURITY -> Disabled Clients. Is it right?
There are currently 250 users connected to the WLC. MAC Filtering is not a scalable solution because as I understand it, we have to specify all the legitimate MAC addresses in the local database.
Thank you.
B.Rgds,
Lim TS

Hi Lim,
As you have discovered, the Mac filtering on the WLC is an Allow (based on Mac address) rather than what you need which is a Deny (based on Mac address). I have not tried this feature but I think you are on the right track in using the Exclusion List (Blacklist) feature. Have a look;
Use SECURITY > AAA > Disabled Client then click New or MONITOR > Clients then click Disable to navigate to this page.
This page allows you to manually Exclusion List (blacklist) a client by MAC address.
Add the MAC Address and an optional Client Description for the client to be disabled.
Note When you enter a client MAC address to be disabled, the Operating System checks that the MAC address is not one of the known Local Net clients ( Local Net Users), Authorized clients ( MAC Filtering), or Local Management users ( Local Management Users) MAC addresses. If the entered MAC address is on one of these three lists, the Operating System does not allow the MAC address to be manually disabled.
Hope this helps! Let us know.

How to block a single table for a single user

Hi all.
I want to block a single Z table for a single user. How to do this? If he/she tries to display data using SE16 or SE11 Tcode he/she should get an error message.
Regards,
Prajwal K.

Hi Prajwal,
We can use the function modules ENQUEUE_E_TABLE for locking tables and the function module DEQUEUE_E_TABLE for unlocking tables. With this method, we don't need to lock objects in order to lock the tables. In other words, any table can be locked/unlocked using these function modules.
Check this sample code:
*Locking Table*
data:
varkey like rstable-varkey.
varkey = sy-mandt.
locking the tables............................
call function 'ENQUEUE_E_TABLE'
exporting
MODE_RSTABLE = 'E'
tabname = 'MARA'
varkey = varkey
X_TABNAME = ' '
X_VARKEY = ' '
_SCOPE = '2'
_WAIT = ' '
_COLLECT = 'X'
exceptions
foreign_lock = 1
system_failure = 2
others = 3.
Hope this helps you.

Single Port Forwarding on a WRV210 router

I was wondering if anyone can tell me how to forward a single port to a different port to a specific computer for the WRV210 router?
I would like to forward port 10100 to port 25 to my mail server. There are times when our people are at a hotel and they block port 25 and I have done this in the past on a BEFSR11 and BEFSR41 router. There does not seem to be a Single Port Forwarding setup page and the Port Forwarding setup page only allows you to forward a range to a specific computer, it does not give you a different port you can assign an incoming port to.
I have the most current firmware revision, 2.0.0.11, and Hardware Version WRTR-221G_V01.
I look forward to any replies.
Fred.

Will it ever be able to support this? seems like a pretty reasonable request since this device is billed as a small business device.
so far i have spent over 1000 dollars on cisco gear first 2 rvs4000 to do BO vpn
then 2 wet200 thinking i would be able to create a bridge to my garage while wireless users could surf. little did i know that the wet200 could not be an AP.
i then went looking for a cisco small business AP only. could find one at any local retailer. so i bought the wrv210 and removed my rvs4000 seems i just downgraded myself. i should have just gone out and bought a $40 dlink AP.
very disappointed. hopefully you can share my experience with someone who can explain why a small business device wouldnt want to use port redirection.
If you see a bunch of used cisco small business gear online thats me,

How to interface AXI BRAM Controller with Block Memory generator in Single Port ROM(standalone mode)

Hi,
I initialized the block memory with coe file to use it as single port ROM in standalone mode. So, the data width of ROM is 32 bits and depth of 62000(this would need 16 bit address for reading). AXI BRAM controller was instantiated in Block design and data width was set to 32.
But upon synthesis, I get following error
[BD 41-1228] Width mismatch when connecting input pin '/blk_mem_gen_0/addra'(16) to net 'axi_bram_ctrl_0_bram_addr_a'(14) - Only lower order bits will be connected, and other input bits of this pin will be left unconnected.
So, the problem is BRAM controller 's interface which has bram_addr_a of only 14 bits. This is strange. I don't know how bram_addr_a width is determined?

,
Are you sure you have 62000 x 32-bits in your coe and not just 62000 bytes? That could explain the 2-bit difference. 8-bit bytes versus 32-bit words.
I tried this with Block Memory Generator 8.2 (Vivado 2015.1) and looks ok. Setting up a Single-Port ROM with 32 width and 62000 depth shows addres Width A: 16 in the Summary and the generated files show 16 bit address as well:

How to Block / Hardening of "Unused Ports" in OracleAS-10gAS

Hi All,
I have installed Oracle 10gAS PatchSet-2 9.0.4.2.0 and Windows-2000 SP-4 OS. The Both instances (INFRA & Mid-Tier) are installed on same box. My AS is working fine and all components are working great.
+
I can find-out the ports being used/configured by 10gAS of this installation. Rest all other Ports are open as such on this OS and are not being used. So basically i want to "Block all those Unused Ports of this 10gAS installation"
1. Is it Possible..? If Yes! how to start about this.
2. Does Oracle Provide a Documentation on this or the details of this is included anywhere in any of the Docs.?
This has been pointed out by one of our Corporate Auditors who has audited our entire IT Infrastructure setup and given us that comment. Can anybody would help me in this regard or suggest me tips / docs. which could be useful to me. Looking for ur help.

Hello,
I would clarify what i need and intend to do......
Let say my HTTP Server is configured and listening at port 7779 & 7778. And the range of this is 7777 - 7999 as provided by App.Serevr.
SO i want to block all the ports of above range and ONLY want to open or allow requests coming for Port No. 7779 or 7778.
What all is being used by App.Server is know to us and we can find it out and list it....but how to block them...here in App.Server.

Hi Vijay,
Here's something to start with, you should be able to complete it.
First, combine your select and update statements:
update vt_mlr
   set aggregator_clli = field1
      ,aggregator_vpi_vci = field_2_n_3
      ,aggregator_slot = field4
      ,aggregator_port = field5
where user4 is not null;Then put these two
C1 := INSTR(vt_mlr_record.user4,' ',1,1);
Field1 := SUBSTR(vt_mlr_record.user4,1,C1-1);into
Field1 := SUBSTR(vt_mlr_record.user4,1,INSTR(vt_mlr_record.user4,' ',1,1) -1);And put it into the update statement, removing reference to record
(I have also removed default values for position and occurrence in instr function):
update vt_mlr
   set aggregator_clli = substr(user4, 1, instr(user4,' ') - 1)
      ,aggregator_vpi_vci = field_2_n_3
      ,aggregator_slot = field4
      ,aggregator_port = field5
where user4 is not null; I think you can do the rest from here ;-)

HT3576 how can i verify that the network or firewall is not blocking access to port 5223.

Talk to someone who knows something about networking and/or firewalls on an appropriate forum.
Configuring your network and/or firewall is beyond the scope of this forum, which is devoted to issues using the iPhone.

HT3576 How do you, verify that the network or firewall is not blocking access to port 5223.

How to block outbound port in Solaris 10

Hello,
I would like to block OUTBOUND telnets (port 23) - Let me repeat it's OUTBOUND (not inbound).
I need to do it on Server level (not Firewall level).
Any help would highly be appreciated.
TIA
Prvn

Yes, you need to use ipfilter.
You can filter either inbound or outbound.
There's information in docs.sun.com on how to use svcadm to turn it on and there's an ipfilter mailing list to help you figure out how to use it.

Examining block diagram- ports on VI- How do I determine which port is wired

Trying to figure out how a block diagram is wired with a a vi that has lots of ports. Is there a way that I can identify where the wire goes on the vi?

As tst said, you can triple click to see the entire wire. Some people don't wire properly, with wires going underneath objects. If you look closely at the attached picture, you can see the highlited wire (the one surrounded by dash lines) goes to the top right corner of the object it is wire to.

How many mac-addresses a single port can store ?

How many mac-addresses a single port can store ?
And also what is the max limit for mac-addresses on a switch ?
Regards,
Chandu

Hi,
I don't think there is a limit per port.
The limit is the max number of entries in the CAM table so if for example the CAM table limit is 8000 and you already got 7200 entries you can have the 800 enties on different ports or on one port.

How to make single port fowarding for camera by using airport extreme ???

hi
I have airport extreme model no A1143 (apple)
when I was using linksys ,I have camera
I reserve IP local for camera and then by aplication single port foward I put IP local for camera so I would get for the picture or video
Is any body can help by using apple airport extreme model no A1143
where should I put the IP local for the camera ?which application
thanks
Message was edited by: charlie368

charlie368, Welcome to the discussion area!
Using AirPort Utility you can configure the AirPort Extreme base station (AEBS) to forward the port(s) to the camera. However the camera will need to be assigned a local IP address. The default local IP addresses are in the 10.0.1.x range.
To get to the camera from the internet, you would use the IP address provided by your ISP. This is the one used by the WAN side of the AEBS.

Hi Yail,
I think you can't close the purchase order with the stored procedure.
Try to catch the Event when the user click on Cancel button.
So you can list the vents with event logger : https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/ede3be37-0e01-0010-1883-cd1b5293473e
You can block the cancel button and force the user to create the purchase order.
Hope i help you
Best regards
