Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

I'm looking for utilities/methods to monitor my organization's Server 2016 network that will let me know (via email alerts) any time that these items go offline:

- Server 2016 AD domain controllers
- Wireless Access Points (WAPs)
- Network Attached Storage Device (NAS)
- SonicWALL firewall
- Primary internet service
- Fail over internet service

I am also interested in any monitoring solutions that will let me know if the Server 2016 hard drives are running low on space, etc.

What are some good website services or other software that will allow this to be done using methods such as pings or SNMP monitoring?

What does it mean to be "Always On"?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

We are in the process of refining our alert and notification management processes.  One of our requirements is to implement a tool that will allow us to centralize and display our alerts or notifications into a single web-based console with color coded priority.  Additionally, we would like to have the ability for staff to acknowledge an event resulting in the event being removed from the console or color changed to green.  Does anyone have any suggestions for applications that could fit our needs?

Thanks

I Have 3 Switsches A,B,C

Switch A is connectet to B, Switch B is Connected to Switch C

Switch A is configured
spanning-tree vlan 1-4094 priority 8192

Switch B is configured
spanning-tree vlan 1-4094 priority 16384

Switch C is Configured
spanning-tree vlan 1-4094 priority 24576

Now I will Chang the Values

SW C gets 8192
Sw A gets 24576

Is there any disruption taking place by a new spf calculation, even if the Switches in a Row?

Looking to add a Skills table to a database of IT Consultants. Can anyone point me to a list of skills required by a large IT department? I'm thinking even a solid list of current enterprise programming languages would help.

Dear Wizards, can you please suggest on this scenario?

If a physical host (with 4 physical NICs) connect to Core Switch Cisco  3925, can we use the Link Aggregation Control Protocol (LACP) to increase the bandwidth for that host? And if so, how to increase the maximum bandwidth for virtual NIC of VMs inside that host?

Many thanks in advance!

hi guys

Are any of you working on implementing GDPR that plans to come into effect next March?

If so, do you have a list of things that need to be implemented technically on infrastructure, storage and network security?
I am looking for something that would have a list of 'to-do's' like:

"Must implement password complexity of one letter, number and eight characters that change every 30 days"
"Transfer of data from local source to destination must be recorded and its location known"

I just made the above up, but basically are there any lists that one could follow as guidance for the entire infrastructure?

Thanks for helping

Hello, I have deployed a HP MSR router into production but I am having 2 issues ...

I can connect to the web interface fine on IP 172.19.60.20, but when I try to telnet or ssh to it I get a "connection refused". What do I need to do in order to allow telnet and ssh through this IP?

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

We have a Class C network and are running out of IP addresses.  We have multiple switches throughout our company and don't want to incur the expense of upgrading all of them to be VLAN capable.  In order to expand our addresses, is it possible to only upgrade one of our switches to a VLAN capable switch and configure it as follows:
1.) The DHCP server is plugged into one of its ports which is configured to be on the default VLAN.  
2.) Any other switch plugged into it will be plugged into a port configured to be on the default VLAN.  
3.) Any other device (printer, computer, etc.) plugged directly into it will be plugged into a port that is configured to be on a secondary VLAN.
4.)  The DHCP server is configured to hand out a different scope of addresses for devices on the secondary VLAN.
5.) The switch is configured so the VLAN's can communicate with each other.

Again, if all we need to do is expand out addresses, is it necessary that any of the other switches are VLAN capable?  Does anyone have a alternate, perhaps simpler way of expanding the addresses?  We could convert to a Class A or B network.  Please advise, and thanks in advance.

Looking for an elegant solution.

Have VOIP PBX system on the LAN that connects to a SIP trunk provider. Have 2 ISP circuits and a basic Fail Over - one circuit is DSL. When the primary circuit goes down, fails over to the DSL. I want to block traffic from the VOIP PBX through the DSL circuit because it's too slow (The PBX will actually failover to its POTS lines if it can't reach the internet, which is what I want)

Access rules don't work because they are zone based and the PBX is in the LAN zone.

Was advised to specify the outbound interface in the NAT policy to the interface of the primary circuit, but this didn't seem to work because there's a default policy that kicks in for Any outbound interface.

Hi, I realize that I do not have a large enough network to generally require subnetting, but I am temporarily hosting one of my client's systems while they rearrange their business. They currently have a Windows 2008 SBS with a domain and 5 Windows 7 clients. My home/office had a Windows 2003 SBS and a domain, but I am willing to remove the server and domain from my installation, as it is not really needed. I have a single connection from my ISP (Comcast) with the Google Wifi mesh network (3 router/AP's) serving my various pieces of equipment (workstations, printers, Tivo's, wireless devices, etc.) Although I could simply shut off one of the DHCP servers and put all my client's equipment on my network, I would prefer to keep them separate. Also, we both plan to RDP into our various systems.

The question is, what is the best way to handle this? I am thinking I will have to provide a router at my ISP modem that will split my network into two sections (subnets???) that I can put my Google WiFi system on one and their router on another. That said, I am just guessing and would be happy to hear advice.

Thanks you

Hello

We need to connect to a router which we do not have direct connection via BGP  , it is in an other datacenter

Our Datacenter .   ----------------  INTERNET ---------------- Other Datacenter ------------- Our server
Juniper MX                                                                               Their Router  <--- BGP <--------  |
         |_______________________________________GRE TUNNEL _____________________________|

we need to put a server on their side and need to complete bgp over it.
How should we do this  what should be the best operation for this ? gre tunnel or anything else ?

How can I find all traffic logged from 172.18.128 using Splunk search? This much be the simplest thing. But I can't get the dern thing to return a thing!

We access an external vendor's site who provided us some sort of service.

However, about 300 of our staff, mostly contract staff needs to access this
service but they currently are not granted Internet access on their PCs, so
we permit by firewall rules for entire organization to access that vendor's
site as going by proxy, we'll need to grant 300 proxy entries (ie by their
AD Id) to 3 URLs as that site will call/redirect to 2 other URLs.

By permitting at firewall rules & letting these contract staff bypass the
proxy, the contract staff can only access these 3 URLs & not any other
links/sites on Internet so this is still "secure" in my view as these 3
URLs are "trusted" sites.   This method of bypassing proxy is also to
facilitate that should new contract staff joins, the staff could access
as the 3 URLs while if we go by proxy, each time a new staff joins,
have to request for it & each time a staff leaves, have to remove that
staff's AD Id from proxy: quite an enormous admin task (for the
proxy admin as well as supervisors of these staff).

Q1:
Now, we just found that this vendor has coded another module to call
Google's "Captcha" service (which is  www.google.com/..... ) : what's
the entire subnet range of google.com ?  Is it a Class A, B or C or a
mix of many Class C  ranges ?

Q2:
Our firewalls can't resolve via public DNS currently so if permit to
access a large range of public IP, what's the security/risk implications?
Any other safe way …

We have a couple of servers that requires "outgoing" access to PlayStore & Appstore
from our Development as well as Production environmt.

As Appstore is a Class A subnet while Playstore is rather large as well (I don't know yet
what are its subnet ranges), what are the best ways to secure this?  Are the following
reasonable ways ?

I heard permitting too wide a range is risky.  Why?  Can appstore/playstore's IP addrs
range get spoofed or those 2 stores can get compromised or what's the reason?


1. Production has to go thru our proxy as our proxy resolves the URLs of appstore &
   playstore?

2. As our Development does not have its own proxy & has no connectivity to our
   Production proxy, permit only about ten Class C ranges for Development/testing
   purpose.  Ten Class C means 2540 IP addrs

3. Any other best practices to secure this?

4. Would placing these app servers behind WAF help?

if you replicate data between your primary SAN to a DR SAN, what assurances and checks need to be performed to verify the health/reliability of the link between the sites and the replication process? What risks are there with such a setup, and what best practices/monitoring need to be in place to minimise those risks? what evidence could be requested to verify these risks are well managed with best practices?

Our firewalls are not sync'ed to public DNS so we can't create rules by URL of playstore or appstore.

Our corporate mobile devices need to have push notifications & apps install :
what's the range of IP for appstore & playstore required & the ports to permit?

I heard appstore is a Class A subnet while playstore is probably a Class B:
is it a good practice to permit firewall rules to such big subnet ranges ?

We have just deployed a Cisco Meraki wifi solution and are trying to set up our wifi networks. However the domain is setup as XX.local.
the commercial cert authorities will not  give  a trusted certificate for XX.local, so we a trying to work out how to deploy a SSL that  is trusted to make wifi for things such as BYOD work seeamlessly , We have considered self-signed but that shows as untrusted, we also need to open  up security on trusted machines to allow it. Has anybody done this or got a good idea

Can someone please explain 2 things with Zabbix 3.2

1.  How do agents work?  What is the difference between active and passive?  Can you have both on at same time, what is the best and if you do active agent I still need the ports open below correct?  

2.  What ports need to be open where and push or pull?
So from what I understand it uses two default ports.
10050 for Agent
10051 for Server

So the monitored host needs port 10050 open and then the agent sends back information to the Zabbix Server using port 10051?  So it goes from host 10050 to server 10051?

Hi,

Earlier this week we switched ISP's and started to use a new physical router with a different IP address on our lan.

At the same time we updated the default route on the Extreme switch so that it used the IP address of this new router as its gateway (therefore internet traffic goes out via this new router) .   The default route on the extreme switch is configured to use the "VR-Default" VR.

Everything has gone well with our production network, but we also have WiFi connections on a number of different  IP ranges (away from our production network).  We are unable to get an internet connection to clients on these WiFi networks.

These WiFi networks are also configured to use a different gateway (with an Ip in the range of the network) which ultimately returns them back to the the Extreme switch.  These WiFi networks/routes are also configured to use the "VR-Default" VR.

I would like to understand how I can examine the details/configuration of the 'VR-Default' VR to understand what IP address it is using to route out to the internet on.

We have two IP ranges at our office. 10.0.0.x (Static) for the internal IP phones and 192.168.101.x with  DHCP for the office PCs, etc.
The internet breakout is via the default gateway 192.168.101.254.

We run a Software based PBX that runs of a windows 10 PC. This PC has 2 NICs.
NIC1 - Static IP for the 192.168.101.x range for office network connectivity and internet.
NIC2 - Static IP for the 10.0.0.x range to connect to the phones.

How can I get the 10.0.0.x range to get internet access through the PC that have both NICs and IP ranges?
