Display just the configuration typed in Cisco Router.

I wonder if there is a command like Show Running-Configuration, that will display just the configuration I manually typed.

For instance if there are interfaces that I have not assigned ip addresses, they will now show up.
the same for other gibberish that I have not typed, like:

boot-start-marker
boot-end-marker
!
aqm-register-fnf
!
!
no aaa new-model
clock timezone CET 1 0
mmi polling-interval 60
no mmi auto-configure
no mmi pvc
mmi snmp-timeout 180
!
!
!

etc..

Dear Team, we are planning to deploy the IP PBX (Asterisk) on an Ubuntu server. As my understanding, we can utilize the SIP trunk configurations and lease an VoIP service from ISP, then we do not need to purchase any Voice Hardware card for server, just need a dual Network interface card, am I right?

For example this diagram, the phone calls routes from IP PBX to ISP voice service via an MPLS connection

Internet ----- router ---------- switch ----------- IP PBX (Asterisk) ----------------mpls connection ---------------- ISP for voice service -------> go out for phone Calls

But can we do like this?

go out for phone calls <--------------------- Internet ----- router ---------- switch ----------- IP PBX (Asterisk)

Can the Internet line serve both voice and data? Do we need to inform the ISP for that change?

Many thanks for your help!

How to setup a wifi network with SOHO router plugged into switch and get IPs issued from DC hosting DHCP server so wireless devices can communicate with wired devices?

I have a Server running Server 2012 R2 that provides DHCP services to the devices wired directly to our switch. If I have the WIFI SOHO plugged into the switch to get an IP on the same VLAN as the wired devices how can I direct my wireless devices to point to the DHCP server to receive the IPs rather than the wifi router providing this service?

I have a question about subnetting/supernetting at /28 to two /29s

if I start with a /28 block with the following info:
IP Block x.x.x.224/28
Gateway x.x.x.225
First Usable x.x.x.226
Last Usable x.x.x.238

The gateway for the first /29 stays the same (I believe).  What then is the GW for the second /29?  Wouldnt it be outside of the range?  

thank you

SERVER 2016 RRAS/VPN ISSUE-VPN client can connect but can't access any LAN resources or ping any LAN addresses. RRAS server stopped working about 2.5 weeks ago for some reason. We have tried to issue addresses directly from RRAS rather than use our DHCP server with no joy.

Setting up a new copier in the office next week.  Will network it with a static IP.   Windows 2008 R2 environment.  What do I do on the server side of things so the new copier will auto install on each computer I setup on the domain? (group policy?)  What about computers that are already on the domain, will gpupdate/force work?

I have created an SSRS report and deployed it to the SQL report Server location.  I want to set this report up so it executes at a certain time and creates a pdf in a network folder. However when I click subscribe I get the error "Subscriptions cannot be created because the credentials used to run the report are not stored, or if linked report, the link is no longer valid." In the  credentials section of the data source of the report I am using Windows Authentication. The only way the report will execute is with Windows Authentication . I have one other report that is set up this way successfully. That report is using a different SQL database. One set up by our ERP providers. The credential setting on that report is do not use credentials. Admittedly my understanding of the security portion of SQL is weak. Any help would be appreciated. Thanks.

On a small server 2008 R2 network we decided to change from PPTP VPN and decided on SSTP. Having opened port 443 on the router, added a certificate etc etc when we tested things it didn't work. On looking at the error logs it would appear that when we update Routing and Remote Access - Server - Properties - Security Tab - SSL Certificate Binding it looks to update without an error but in the error log we get the following:

Event Properties - Event 22, RasSstp
The secure Socket Tunneling Protocol service could not be configured to accept incoming connections. The detailed error message is provided below. Correct the problem abd restart the SSTP service.
Cannot create a file when that file already exists.

Then when I try the VPN with the SSL Certificate binding is set to Use HTTP the client VPN error is "The token supplied to the function is invalid". If have a certificate selected (which creates the error above) we get the error "No Connection could be made because the target machine actively refused it" .

Can any body help
Thanks

OK, so NetBIOS is "going away".....  What does that really mean?  I ask this in the context of the Network display in Windows 10 Windows Explorer.
Lately, the Network display list has been getting flaky.  It's time to illuminate why that is and what to expect in the near future.  Actually, what to expect today.
Now, I am well-experienced with peer-to-peer networks - so that's my focus here.

Regarding the Network list of computers:
I know well the context of NetBIOS and the Master Browser and the historical list of computers in the Network display.
What I don't know is what comes next?
What I don't know is what to expect in the near term with networks of Windows 10 computers.

What I do know is that there has been "flakiness" of the list that's displayed.
What I do know is that lists have changed from 100% NetBIOS to mixed NetBIOS and WSD and now to 100% WSD as the Discovery Method.

And, in the process, the Network list of computers has become flaky.
Some lists are short.
Not all lists, from computer to computer, are the same.
Some lists are long and have but one computer missing (seems like always the same one!).

I have been told numerous times by Experts that NetBIOS "is going away" by 2020. I'm not sure what ALL that means.
Windows 10 continues to display a "NETWORK" list in Windows Explorer doesn't it?
If you elect to show "Discovery Method" as a column in the Network list display, then you will see either NetBIOS or WSD for each computer …

Strange problem,,

We have four ESXi 6.0 Servers.  Each ESXi Server is connected to a set of ports on a switch in VLAN 10.

The ESXi IP range is: 192.176.1.0/24.  
ESXi-1 =  192.176.1.11  - switch port 4
ESXi-2 =  192.176.1.12 - switch port 3
ESXi-3 =  192.176.1.13 - switch port 2
ESXi-4 =  192.176.1.14  -  switch port 1

We have also desktop VMs that are in 192.176.2.0/24 used with Horizon View .

We have a pfsense router that routes traffic in 192.176.1.0/24 to 192.176.2.0/24 so we can get to the ESXi servers as well as vCenter (on 192.176.1.10).
We no longer needed ESXi-4, so we moved the VMs and powered it down.

The other day, we added a new ESXi 6.5 server and the IP set to 192.176.1.25 (ESXi-5) and I took the cat6 cable that was connected to nic 1 on ESXi-4 (console) and plugged it into nic 1 on ESXi-5 (console).
The port on the switch and ESXi Server are green.

When I am on a desktop VM (192.176.2.10), I can ping the all the ESXi Servers except for the new 6.5 ESXi (ESXi-5) that was added.  
However, if am on vCenter (192.176.1.10), I can ping all of the ESXi Servers including the new ESXi-5.  

I am not sure if I missed something here, but the routing seems not to be working?

Any ideas

Hello Everyone,

I have a SoniWALL NSA 3500 that I am trying to configure to open port 8000 for a Network Video Recorder (Hikvision). I want to port forward.  I created an object for port 8000 and then for the internal IP address that the recorder is going to use. I then went through the Public Server Wizard and and entered the internal IP and then the wizard went ahead and added our WAN address and then created the inside, outside and loopback parameters.  For all intents and purposes this should have opened port 8000 once I went through the wizard.  

Issue is when I try accessing from outside (or even inside my LAN network) using our WAN IP and then adding the 8000 suffix (x.x.x.x:8000) it's not reachable.  I believe I should receive at least a SonicWALL test page, correct?  Even if the device is not plugged into the switch yet I should still get something from the SonicWALL I believe.

Can anyone tell me if there is anything else I can do to make sure that port is open?  Web tests still say the port is closed.

Any help would be most appreciated!

Thanks!

Hi Experts,

                   in the office there is a domain network with the usual lan access to employees etc..

People often visit the office with laptops and need to connect to external resources, which is a concern because domain resorces are then visible to the visitor.

We would like to change that but can't figure out how to do it.

We're happy to purchase an WiFi access point and let it do the work for us, but so far we do not see any access points capable of that. We were hoping for something like an access point with a NAT so that we could use different IP addresss on the AP (eg. 10.0.0.1/32).

I hope that makes sense ?

Thanks, Chris.

so yesterday we had to reboot our Cisco core switch in the datacenter.  Today some users are having email issues where Outlook wont connect to Exchange unless they do a IPCONFIG /RELEASE and reboot their PC.  I had my IP set as static and I had to change it to get Outlook to connect.  Any ideas?  Do I have to restart the rest of our IDF switches (which weren't rebooted but connect back to the core switch in the datacenter).  Thanks!

I have setup a new server (SERVER01) in azure exactly the same as all other servers in the domain.
I can ping the server ok from all servers.

However, I cannot browse to any network shares from other azure servers (With the exception of azure domain controllers)
I can also browse from our local on-premise network servers, whether they are domain controllers or not.
All servers are part of the same domain and connected in a hybrid setup via a S2S VPN.

I have tried both \\SERVER01 and \\192.168.0.10. The error is just "Windows cannot access \\SERVER01"

All of our Azure servers are running Windows Server 2016.

Hi Experts,

we use PRTG to monitor the network / devices.
The vms were being monitored under the hosts.
so each vm host within vcenter had a bunch of servers
as soon as we do work on the network and the servers migrate to another host, netmon starts sending notifications that everything is down basically.

i am trying to re-design it so netmon is monitoring the vms no matter where they land directly.
what is the best way to go about it?>


thank you in advance

Are there any standard risks (by this I mean those that could affect any VM regardless of its purpose) that can be used for risk assesment purposes for virtual servers above and beyond security related risks/common issues. We need to assess all common technical risks be those performance availability security for all virtual servers which process critical services. And some insight into common causes which make the aforementioned issues happen and occur.

Hi,

We have a SmartThings hub and SmartThings power outlet.

There is a device plugged into the SmartThings power outlet.

Also, we have an Amazon Echo Dot connected with the SmartThings power outlet.

There is also a Google Home in the room.

Ideally, what we would like to happen is that if someone turns off the SmartThings power outlet via the app or Amazon Alexa, that the SmartThings power outlet would turn back on after several hours, example 4 hours.

This would mean the device connected to the smart outlet could only ever be turned off for 4 hours at most.

Is there a way of configuring this via SmartThings, Amazon Alexa or with some other type of smart power outlet?

Thanks,
Robbie
