Ping Access Download

I cannot seem to find a definitive answer on this. We have Aruba AP-225s setup as campus APs using forward mode of tunneling. I can ping the APs from the controller and when connected wirelessly, but I cannot wired. I have seen several posts where this is expected behavior. I also also talked and seen information where this can be fixed through a configuration change. However I am unable to find what exactly I need to change to fix this. I also think this is possible because I worked with TAC before on another issue and they had me try and ping the AP from my computer and I told them I could not and that I could only ping from the controller or via wireless. They seemed surprised to hear this. If anyone could give me a definite answer on this that would be great. Thanks.

If you have control plane security enabled ("show control-plane-security "), there is an ipsec tunnel built between the access point and the controler for management traffic. Historically there was an issue where if a management device is on the same VLAN as the controller, the access point would respond to the ping from that device through the controller's tunnel and the traffic would be dropped. If you ping the access point from a different subnet, it would not send it through the tunnel, so it would work.

Ping is not essential for the access point to work, because an access points is never managed externally from anything besides the controller's ip address. Turning off control plane security would fix your issue, but it involves some downtime and it does nothing but allow you to ping your access points from the subnet of the controller, which is not important.

I understand that ping is not essential for an access point to work. But when you moving from a system where this was part of the troubleshooting process for the Tier 1 and Tier 2 support it is helpful if as much of the system and available troubleshooting methods can be migrated from one system to the next. If that is not possible with Aruba, which I find odd, then we will just have to convey to them that Aruba doesn't support that kind of troubleshooting method.

I still find it odd that when I had another TAC case not related to this, that the first thing the TAC person asked me to do was ping the AP from my PC. Sounds like there is a bit of a disconnect there.

Microsoft Entra application proxy has partnered with PingAccess so that your Microsoft Entra customers can access more of your applications. PingAccess provides another option beyond integrated header-based single sign-on.

With PingAccess for Microsoft Entra ID, you can give users access and single sign-on (SSO) to applications that use headers for authentication. Application Proxy treats these applications like any other, using Microsoft Entra ID to authenticate access and then passing traffic through the connector service. PingAccess sits in front of the applications and translates the access token from Microsoft Entra ID into a header. The application then receives the authentication in the format it can read.

The Application Proxy connector is a Windows Server service that directs the traffic from your remote employees to your published applications. For more detailed installation instructions, see Tutorial: Add an on-premises application for remote access through Application Proxy in Microsoft Entra ID.

Claims Mapping Policy (preview) for attributes which do not exist in Microsoft Entra ID. Claims mapping allows you to migrate old on-prem apps to the cloud by adding additional custom claims that are backed by your ADFS or user objects

You can do policy definition and assignment through PowerShell or Microsoft Graph. If you're doing them in PowerShell, you may need to first use New-AzureADPolicy and then assign it to the application with Add-AzureADServicePrincipalPolicy. For more information, see Claims mapping policy assignment.

Those steps help you install PingAccess and set up a PingAccess account (if you don't already have one). Then, to create a Microsoft Entra ID OpenID Connect (OIDC) connection, you set up a token provider with the Directory (tenant) ID value that you copied from the Microsoft Entra admin center. Next, to create a web session on PingAccess, you use the Application (client) ID and PingAccess key values. After that, you can set up identity mapping and create a virtual host, site, and application.

In my network, I need to be able to deny ping access from one direction, but not the other. (So for instance, in my network, I need for the group of systems with IP address 192.168.102.0 to be blocked from accessing the group of systems with IP address 192.168.101.0, but not vice versa; 192.168.101.0 must still be able to ping 192.168.102.0, but 192.168.102.0 must not be able to ping 192.168.101.0).

I initially tried doing this using access lists on the Master Router, but that did not work at all; packets were still able to ping in both directions even when I added the access list to a particular interface.

I then tried the IPv4 Firewall tab on the Desktop of each system within the group, and while that was very good at stopping access in one direction, it also completely stopped pinging in the other direction too, even if I allowed ping access from the sender IP address group on the receiving system.

Does anyone know what my issue might be? And what should I do in order to rectify it (should I use access lists or IPv4 Firewall?)? Any help would be much appreciated; I've integrated my Cisco Packet Tracer file within a zip folder to give you some idea of what I'm working with here.

It should be fairly straightforward to prevent ping from 192.168.102.0 to 192.168.101.0. Configure an extended access list and apply the access list inbound on the router/switch interface where 192.168.102.0 is connected. In the access list the first statement should deny icmp echo-request where source is 109.168.102.0 and destination is 192.168.101.0. The second statement in the access list should permit ip traffic where source is 192.168.102.0 and destination is any.

This would prevent ping request from 192.168.102.0 to 192.168.101.0 and would not impact ping request from 192.168.101.0 to 192.168.102.0 and not impact ping response from 192.168.102.0 to 192.168.101.0.

BTW, what @Richard Burts suggests is a belt and suspenders approach (and is fully correct). Just wanted to note that if you block ping requests in one direction, there should be no ping replies in the other.

I'm having an odd problem. We have two PTP650 links, and seemingly randomly they decide to stop responding to pings and won't let me access their GUIs. Traffic and pings through them are fine, but pinging them directly leads to 80+% packet loss, and when I'm lucky enough to get to the login page I'm not able to get past it to the GUI.

We're not using a VLAN. I don't have easy physical access to the units to reboot them, so I haven't tried it. The issue seems to randomly go away on its own, and the uptime indicates it didn't restart to do that.

If the CPU receives unwanted Ethernet frames it discards them, but processing the received frames still consumes some CPU cycles. It's important that the processing needed to inspect and discard unwanted frames does not use up resources needed for the higher priority tasks associated with keeping the wireless link in service.

Thinking it could be a broadcast storm (we have about 4-5 providers with separate VLANs traversing the link) I peeled off one vlan at a time trying to see who the culprit is. I have two different VLANs that if I take them off at the same time the radio recovers to no packet loss and single digit ping times. These seems to resolve for a short period, but then starts up again.

I want to build a simple ping function and get a result of either 0 or 1.But if this function below i keep getting an access denied error, i've tried with several web sites and i always get the same error.

When pinging with -c option, you have to specify the number of pings. When you ping in windows, default 4 packets will send (and recieve, unless there is problem in connection, or you break the process). But in linux systems it pings infinitely. Honestly I don't know the count, I just CTRL+C and break the process after enough count of packets transmitted and recieved:)

All my devices on 192.168 can ping OPNsense and access the internet, but my Raspberry Pi (Fresh installation of Raspberry Pi OS Lite) cannot ping 192.168.0.1 nor use it as it's DNS provider. I actually reinstalled the OS because since I started using OPNsense a couple of days ago, the Pi couln't connect and I thought this was more of a corrupted SD card or some obscure change I did to it.

I discovered shortly afterwards that I was unable to connect to the console of any of the VMs running on the older hosts when using the client on my local PC (workstation VLAN) - Unable to connect to the MKS: Failed to connect to server :902, any VMs on the newer M3 hosts I can open console just fine. When running the client on our network ops server (Server VLAN) I can open console to any VM on any host. The webclient suffers from the same issue, VMs on M3 hosts can connect, the older hosts gives the error. Directly access the running VMs is no problem between VLANs, however they are running on different Intel I340 NICs on a 4 x NIC PCI card added to each server. e24fc04721
