A Cyber Security RX to Protect Your Organization
A Cyber Security RX to Protect Your Organization

Join us on December 13th for a webinar to learn how medical providers can defend against malware with a cyber security "Rx" that supports a healthy technology adoption plan for every healthcare organization.

Hi all, please am submitting a CRQ for a simple static route via vrf
i.e.
ip route vrf  (vrf name) <ip address/mask> next hop.
I know it will not be approve if I did not put a statement about testing.
Please can anyone suggest any simple testing statement for static routing?

We decided not to spend that  60k/year on external consultants services to do scanning for rogue AP/SSIDs.

I noticed the consultant run a software tool on their laptop.  Any tool that could give a decent PDF report
certifying there's no rogue Wifi AP around will be most welcome.   Need something easy to use

Hello,

I'm having some issues removing the start menu tiles in windows 10 through group policy on our 2016 windows server. I exported the start-layout xml file from powershell to use as the standard layout for all of our users in our group policy. Initially the users start menu will have no tiles as expected, but after a second login or so, there will be tiles from Dell.  Even after uninstalling all of Dell's bloatware, there's still a section labeled "Dell" but with no tiles.  Is there any way to make sure that no tiles will ever show?

Thanks!

What is the best option for a router or managed switch for a new fiber connection we have coming into our building?

Any recommendations other than a Cisco switch?

Basically we have a tail coming in with 50/50 fiber and 2 ip’s and 2 businesses need to leverage off it, our business and another.

Both businesses are separate but contributing to the connection and aside from QoS just need something to be able to push 1 internet ip to 1 lan and 1 ip to another.

Was assuming a managed switch or router with a vlan switch to 1 port and a vlan to another. Each business will have their own router and firewall from that point

No data can cross.

So was just looking for the best option and what unit would be reasonable whether a router or switch and just setup vlans

Any assistance greatly appreciated.

We have users that don't have static IPs and need them to gain access to some servers. They do have DDNS with nutpile so wondering if those dns names could be used instead of a source IP.

Our Windows 10 computers request WiFi RADIUS machine authentication continuously (every few minutes). We see this in the logs of our RADIUS server The logs are filling with re-authentication requests.
The WiFi profile is applied by group policy.
Power save modes have been disabled.
Has anyone else had a problem like this?
Thanks for your help.

Get quick recovery of individual SharePoint items

Free tool – Veeam Explorer for Microsoft SharePoint, enables fast, easy restores of SharePoint sites, documents, libraries and lists — all with no agents to manage and no additional licenses to buy.

I am trying to understand the purpose of the number that comes after the "/".
example:
ip prefix-list TEST seq 5 permit 10.0.0.0/2 ge 17

2 means match 2 bits of first octet 10

however whatever I put , the prefix list will care just about the ge 17

to clarify it I have this table before filtering:

R1(config)#do sh ip route 
      10.0.0.0/8 is variably subnetted, 6 subnets, 6 masks
D        10.1.0.0/16 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.2.0.0/17 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.3.0.0/18 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.4.0.0/19 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.5.0.0/20 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.6.0.0/21 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0

Open in new window


if I use : ip prefix-list TEST seq 5 permit 10.0.0.0/2 ge 17
router eigrp 1
 distribute-list prefix TEST in


R1(config)#do sh ip route

      10.0.0.0/8 is variably subnetted, 5 subnets, 5 masks
D        10.2.0.0/17 [90/156160] via 192.168.12.2, 00:00:03, FastEthernet0/0
D        10.3.0.0/18 [90/156160] via 192.168.12.2, 00:00:03, FastEthernet0/0

so what 's the purpose of the number that comes after the slash sign "/", example:10.0.0.0/2

Thank you

Okay... Here's the situation. I have sort of inherited a system. I have a 'working' location and a new location we are creating. Horizon View 7. We use dedicated pools with static machines assigned to users. There is a mix of both Win7 and Linux (CentOS and Ubuntu and something else I can't remember). All the VM's have to autologin to a desktop with a local user. This is a requirement that can't be changed. According to users in the other location, they are able to connect to their running VM's with no issues and it connects to the running session. In testing the new environment, this doesn't work. We get the resource busy or unavailable error. On my Win7 VM that I am testing with, I have installed the console plugin. This allows me to connect directly to the VM with a user already logged in, but I'm prompted for the local user account. Connecting to the Horizon server, does not work. The VM's we started working with at the beginning of this were VM's from the other location. Now we are building from scratch.

We've had our networking guys investigate it was well and according to them, this is all connected at the switch level and nothing is being blocked. I would not rule out networking though.

Any ideas what the issue is or if what we need to do is even possible? I've been told to make this work even though it does seem like it would be easier to just allow console access.

Hi all,

Long time reader first time posting.

I have been asked to setup a web server inside a DMZ that can communicate with an internal database server. We have one external IP address available with port 443 currently only being used for external access to the SonicWALL. The firewall is a SonicWALL NSA 220.

The web server will be a virtual Windows 2016 server sat on ESXi on it's own vSwitch connected to a spare port on the SonicWALL which I will configure as a DMZ port. I assuming I can configure a rule on the SonicWALL that will allow ports 443 and 80 to be forwarded to this web server and allow the web server to only communicate with the database server over 1433.

An external vendor will be configuring the application that will be running on the web server.

Does this sound like a workable solution?

Hi

How yo untag port example 40 in Cisco firewall?

Currently we have situations port 40 was in the server vlan.

If we untag port 40 in the switch It might compromise security issue.

is there a workaround Solutio to untag port 40.

Dear Wizards, is there any free solution for logging management? I found Greylog on the Internet but not sure about its quality. Can you recommend some? Can Zabbiz be used for logging? Many thanks!

I have 7 Intellinet 24 POE Switches, installed in the past 3 months.  2 have never reset.  They are in a building on a separate subnet.
I also have two smaller 8 port Netgear POE switches, they have never reset.

There are 5 units that have at least once reset.  Details below

There are two VLANs, 1 (default) and 2 (VOIP), when everything is working it all works very well, data and VOIP traffic is good

Since their installation I have had three incidents where 1, 2, or 4 of the 9 switches were suddenly and with out explanation reset to Factory Defaults.  (I can duplicate this condition be pressing the reset button as you know)

Incident 1 - several weeks after initial installation and roll out of phones, I came in to find that 4 of the 9 switches were factory reset.

I blamed this on my having not changed the default password on the device.  I restored programming, changed the passwords and also put the switches on a private subnet.

Incident 2 - Several weeks later, two of the switches were found in Factory Reset.   Both switches are in areas of our buildings that are accessible to staff (not locked up), I spoke with management and got permission to put a camera in one of the utility closets.  I have not put the camera in, but the belief shared by everyone is that I have.

Incident 3 - 2 weeks later 1 switch (one of the two in Incident 2 , but not the one with the phantom camera.
I reprogrammed the switch, and restored VOIP service.

Some other facts: Two …

VIDEO: THE CONCERTO CLOUD FOR HEALTHCARE

Modern healthcare requires a modern cloud. View this brief video to understand how the Concerto Cloud for Healthcare can help your organization.

Devices:
Google Home,
Aruba IAP-305 (RW)
NordVPN


I am trying to set up a VPN for my Google Home so it will register as being in the US. I am currently in Ireland and have purchased a subscription to NordVPN.  From what I understand, a VPN cannot be put on the actual Google Home device.

I currently make a lot of calls to the US. Google Home offers free calls in the US but is not available here in Ireland. This is one of the main things I want to get from my Google Home.

If the net result of the VPN makes Google Home look like its in the US, I do not want the rest of my tech devices to think they are in that location, i.e all of my other tech devices have locations in Ireland.

interface FastEthernet0/0/0 - 30% (2Mbps LInk)
interface FastEthernet0/0/1  - 50% (2Mbps LInk)

why every time traffice use primery interface as a interface FastEthernet0/0/1, please suggest what need to be changes for traffice move in order, example:-
interface FastEthernet0/1 - 60% (4Mbps Link)
interface FastEthernet0/0/0 - 20% (2Mbps LInk)

Via AWS I spun up a Windows Nano Server node. I can manage this from a management server in the same VPC.
 
Using Powershell, I can access the Nano server, add the server to my network domain, create a sheduled task, create a local user group and add a domain user to it, assign user privileges to allow users in this group to run scheduled tasks.
 
This scheduled task shoud read and write to locations on our networked SAN, which lives in the same VPC.
 
But the Nano server does not allow access to the SAN.
 
if I use the Powershell Test-Path cmdlet, specifying the UNC path to a location on the SAN, it complains that access has been denied.
 
And yes, the domain user has complete access to the locations on the SAN.
 
I also tried mapping a drive letter with net use: same result.
 
I have read every document by Microsoft and every blog post and StackOverflow post I thought relevant. Only 1 other person described the same problem, and has no solution. They were on a forum for Docker, and the Docker team discovered this is a problem with Nano, and not with Docker.
 
In my set-up, I don't use containers, I don't use Docker. I guess AWS runs this Nano instance in Hyper-V, but that is outside of my reach.
 
The Samba firewall ports are open and active (File and Printer Sharing).
 
Have you encountered this problem? How did you fix it?
 
One way I can work around this problem is by reading and writing to the Nano server itself. However, I fear that such would …

Hi,

Let's say I'm an ISP and I lease a 10G transport pipe to an IX (Frankfurt or Amsterdam), with the purpose of buying transit from 2 different tier 1 providers (2 resellers, probably) and peering with content providers.

What happens inside the IX?

Do I get one switch port and I have to rent rack space for my own equipment there? The peerings are physical, with cables between my switches and the peer switches?

Or I only get a VLAN and the peerings are inside the IX main router/switch? And I route the traffic from my VLAN to my peer's VLAN?

Or?

I've googled for the past days, but I'm still confused. Anyone has real world experience with this?

Thank you.
