Management Traffic issue

I need a solution

Hello folks,

Some years ago, when I was working on packetwise 9, i could not access the management ip address of the PacketShaper.S200
We came to see that the traffic from the admin workstation towards the management interface first passes via the LAN-WAN bridge before it reaches the management interface and I was told by support that this was a known issue and there is a command to mitigate this issue

I am seeing the same issue again in another site and unfiortunately, i have missed that command.
Can someone help me with it ?

Regards
Fawaz

7021470: Configuring TCP/IP and LAN Adapter for an IBM System i

Verify That TCP/IP Configured Properly on the System i

TCP/IP is configured properly on the System i when TCP/IP is enabled and that you can ping the host. Verify your system as follows:

Netstat

To ensure that TCP/IP is enabled, enter the following command at the i5/OS command line:

NETSTAT
  • If NETSTAT reports that “TCP/IP is not started,” refer to the section below on Installing and Configuring TCP/IP on the System i.
  • If TCP/IP is configured, you may be prompted to verify the settings.

Ping

To check whether you can ping the System i, enter the PING command at the i5/OS command line. An example:

PING '192.168.1.1'

The above command would have the System i ping a system with an IP address of 192.168.1.1.

Configuring TCP/IP on the System i

To install and configure TCP/IP on the System i, enter the following command at the i5/OS command line:

CFGTCP

When you enter CFGTCP you will see up to twenty-two different configuration options. Verify and configure the required settings below.

  • TCP/IP Interfaces.

The TCP/IP Interface description is typically:

    • Line Description: ETHERNET
    • Line Type: ELAN
  • TCP/IP Routes.

Check the DFROUTE and MTU entries.

    • DFROUTE indicates the router IP address.
    • Set route’s MTU size to *IFC (recommended).
  • TCP/IP Attributes.

Enter the following command at the AS/400 system prompt:

STRTCP

The administrator must start the TCP/IP transport once configuration is complete.

Verify That the LAN Adapter is Installed and Functional

To check whether the LAN adapter is installed and functioning, follow these steps:

  1. Enter the following command at the i5/OS command line:
DSPHDWRSC *CMN
  1. Find Ethernet Port Tokenring Port in the listing. If there is no value for Ethernet Port or Tokenring Port, then i5/OS is not automatically reporting the existence of an Ethernet adapter. This indicates either a hardware failure or that no LAN adapter is installed on the system.
  2. You will need to know the value of the Resource Line Description entry. Note the Resource Line Description value: L_____. This typically corresponds to LAN adapter (Ethernet or Token-Ring) and is directly above the Port resource line.
  3. Select option 5 to display configuration descriptions.
  4. Enter 8 to work with Configuration Status.
  5. Verify that the status is Active.
  6. Option 1-Vary On may be entered for an inactive device.

Checking the LAN Interface (LINE) Configuration

The way you check a LAN interface configuration depends on whether you have an Ethernet or Token-Ring adapter. You will need to know the Resource Line Description value that you got in step three of the Verify the LAN Adapter is Installed and Functional section above. Steps are included in separate sections below.

Ethernet

If you have an Ethernet adapter follow these steps:

  1. Enter the following command at the i5/OS command line:
CRTLINETH

Press F4 any you will be prompted for configuration entries. Do not press Enter. In the Line Description field the recommended entry is ETHERNET.

Keep Your Customers and Employees Happy with a Wi-Fi Network That Just Works

OfficeConnect Wi-Fi makes it simple for small businesses to offer fast, reliable connectivity to employees and guests.

HPE OC20_blog.jpgBeing a small business doesn’t mean that you need to make sacrifices—and that includes your network. The consumer-grade wireless router and switch you bought at the office supply store were fine when you started out, but as your business grows and your staff rely on more mobile devices and applications, the demands can quickly overwhelm your network and degrade the end user experience.

We all know how frustrating it is when wireless connectivity fails or you are waiting for a spinning wheel to access an application. To support your business-critical voice, video and cloud-based applications, you need fast, ultra-reliable Wi-Fi and wired connectivity that’s simple to set up and simply works. That’s what HPE OfficeConnect OC20 delivers.

Ready-to-go Wi-Fi for non-technical users

As a small business, you face big challenges every day, but Wi-Fi shouldn’t be one of them. HPE OfficeConnect OC20 access points (APs) provide your employees and guests with super-fast and reliable Wi-Fi.

With an intuitive mobile app, you can easily set up and monitor your network in minutes—all from your smartphone. The companion Android or iOS mobile app does all the heavy lifting for you. It automatically discovers the new OfficeConnect AP—all you need to do is create a network name and password, and your network is ready to go. When you’re ready to expand, new APs will automatically join the existing network, with no setup required.

With OC20, you no longer have to worry about complex Wi-Fi settings or managing your Wi-Fi network. The APs intelligently optimize your Wi-Fi coverage and performance to keep your employees connected and your applications running at top speed. And with the OfficeConnect mobile app, you can quickly monitor your network at a glance, including wireless performance, how many devices are on and who’s connected to the Wi-Fi network.

Build your clientele while keeping your network secure

Offering guest Wi-Fi can help you build your client base. Today’s customers expect to stay connected while they wait and will quickly find their way to businesses that offer free Wi-Fi. With the OC20 APs, you can offer your customers secure access to your Wi-Fi network. OC20 keeps your guest network separate from your employee network, thereby preventing guests from accessing your corporate data.OC20_2J.jpgOC20_1J.jpg

You can even build your brand by customizing your guest log-in page with your logo or create a guest access schedule that limits access to specific days and times. For example, you can provide Wi-Fi access only during business hours from 8am to 5pm.

The OfficeConnect OC20 APs are specifically designed to keep your network secure and protected. With our customizable website filtering, you can set access guidelines for employees and guests to further protect your network from online threats. For example, you can block access to malicious websites or objectionable content, all with the touch of a button.

Smart managed switches to power your Wi-Fi network

Access local owncloud installation with a domain name

I have owncloud installed on a local server at the office located at a buisness incubator and a web site with a domain name on a remote server.

Current installation:

  • Domain: example.com that points to my remote server
  • owncloud installation with local static ip 192.168.17.98:80
  • incubator’s ip/port 123.123.456.789:1234 forwarded to owncloud’s local ip/port

I can access owncloud installation using incubarot’s ip/port 123.123.456.789:1234 and a local ip 192.168.17.98:80

My goal is to be able to access owncloud using a sub domain owncloud.example.com/

Is this configuration possible?

How can I get my local network machines to call local web server by URL?

I have four computers connected to a single switch – unconnected to the internet.

One of the computers (the large one in the picture) is more powerful than the others and is running Ubuntu, with three live Node.js web servers with different apps on different ports.
The other computers are running Windows.

I want the other three computers to access the web servers by calling a URL, for example

  • files.bugsteins –> 192.168.0.5:3000
  • chat.bugsteins –> 192.168.0.5:3001
  • devices.bugsteins –> 192.168.0.5:3002

What is the best (priority to fastest set up time) way to accomplish this ?

Thus far I have tried Bind9 on the server machine and assigning static IPs and manual hardcoded DNS on the three client machines but it is not working and as I work on it, I figure I will post this question in case someone has a better way.

Extending LAN ports of a wifi router

I have a wifi router which has a built in LAN switch with two LAN ports. I have more than two devices which only support LAN connectivity, which I need to connect to my network.

Is it possible to connect a switch to one of the LAN ports of the router and connect my LAN only devices to this switch? If this is not possible, what else can I do?

Is only a single IP address assigned to a LAN port by the wifi router?

The default frame type for auto-detection on %2 was changed to %3. This type is now the default if no frame type can be detected.

Details
Product: Windows Operating System
Event ID: 9501
Source: IPX/SPX
Version: 5.0
Component: System Event Log
Symbolic Name: EVENT_IPX_NEW_DEFAULT_TYPE
Message: The default frame type for auto-detection on %2 was changed to %3. This type is now the default if no frame type can be detected.
   
Explanation

The frame type is the way the network adapter formats the data to be put on the network. NetWare IPX clients and servers can be configured for different frame types, but for the computers to communicate, they must be configured for the same frame type. The Auto Frame Type Detection allows Windows 2000 to determine which IPX frame type is being used on the network and to set the NWLink frame type automatically. NWLink checks frames being passed to the network adapter to which the protocol is bound. If it detects frames of the type 802.2 or no frames at all, it sets the frame type to 802.2. Otherwise, it sets the frame type to whatever is being passed on the network.

This IPX information message shows the new default frame type.

   
User Action

It is a good practice to double-check that the correct frame type was detected.

Asterisk ghost calls

Problem

We have an Asterisk server hosted externally. On four locations we’ve gotten ghost calls. These are calls with different numbers like 1000, 9999 or 6060. We don’t use these numbers, not even that range.

NB: I’ve asked a question about this before, but that didn’t result in a solution.

A while ago one phone (123) had this problem. This phone was used at home by an employer. I ordered it back, and gave the employer a new phone with a new number (124). I connected the 123-phone in my office, and never had a problem. The 124-phone started to have problems after several weeks, so not right away.

To me this seems like a problem that originates in the home network of the employee.

  • We’ve had this problem in three different homes.
  • All these users have routers at home, so the phones are not connected to the internet directly.
  • We don’t get this problem at the office, I suppose we have better protection there.
  • The problems don’t stay forever. They come and go, then come back.

I’ve looked in the Asterisk logs several times, but couldn’t find anything related.

Questions

I would like to know how this works.

  • Do these calls originate from the home LAN of these employers?
  • Does the Asterisk server play a role here?
  • What can cause this? Is this malware on a laptop?
  • Is it some harmeless process that connects to this phone and causes the phone to think a call is made?

And of course:

  • How can we get rid of these calls?
