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.

are there any free tools which could scan a drive on a file server for potential inappropriate images, based on a nudity type calculation. I know these things exist in forensics communities but I have yet to see anything that is free. we need to do a quick scan to ensure one of our employees has not stored any inappropriate material on one of our file servers.

I have two locations with almost duplicate setups.  
Location 1:  On a network run by a PDC.  The ISP is a cable company.   The one office in this location has 3 computers all connected to the network via a Netgear 5 port switch.  But also connected to this switch is a DSL connection via a dsl modem line to a preset location..  When the users need to connect to this dsl line they just click on the shortcut created on their desktop that directs them to the preset IP address.   All other communication for everything else goes through the regular PDC/cable network.  Using DHCP and automatically sees PDC as DNS provider.  Works great.

Location 2;  On a network but run just by a router, not a PDC,  through the local Cable company.  Two computers connected via an identical 5 port Netgear switch as in the location 1.  They have the the exact same dsl line via the same dsl modem connecting to the same IP address as in location 1.  The problem is that you can only connect to one or the other in location 2.  If you want to connect to the dsl location via the dsl modem, you have to disconnect the cable from the router from cable company at the Netgear switch.   Or if you want to  use cable you need to disconnect dsl modem from switch.  Also running DHCP and DNS being provided by either the DSL or cable depending on which you are using.  

What would cause one to work and the almost identical one won't?

Hello Experts
I am wondering if I can use a SNMP sensor to monitor all wireless APs from Aruba Wireless Controller.  If one AP goes down, I should receive email notification.
We are currently using PRTG for Network Monitoring.

I would really appreciate any help.

Hi,

My apologies if I'm unable to put the question right, I am a beginner and would not understand why Im not able to log into the redundant device. These are Cisco WS-6509-E running the WS-SUP720-3B

I am trying to do an IOS upgrade on 2 devices

Device A

Device B (Redundant to Device A)

These are Access level switches and Im using SecureCRT to log into the devices. I am successfully able to log in the Device A and back up the configs. However when trying to log in to Device B - it gives me the below error

ssh: connect to host xx.xxx.z.15 port 22: Connection refused

IP of device A is xx.xxx.z.14.

What can be done in this case? Thanks in Advance !

For a large enterprise with over 120 locations nationwide across the WAN, our operations team needs to make updates to acls on Cisco ASAs and routers based on CCB approved changes.  Approved changes come in on a regular basis.  The problem is this becomes a maintenance hardship as a single change at one site, becomes a similar change at the majority of the other sites.  A single change has to be applied up to 120 times.  Looking for an automated way with a good management tool.  For now, there are no changes to the acls on the perimeter routers, changes only made to the acls on the ASAs.

The IP addressing scheme for all the sites are 10.10.w.x local LAN behind the firewalls, and 10.20.y.z behind the routers.  The first two octets are always the same site to site.  The third octet is the site identifier.  For example, for 10.10.27.32 the 27 represents Kansas City, for 10.10.29.32 the 29 represents St. Louis.  In both examples, the 32 represents a SQL server, and all sites use the last octet to represent a device that is identical for all the sites. So 32 last octel is always the site SQL server, last octet 45 is always the site DNS server, etc....  

When an approved firewall CR comes in for access to all the DNS servers at all the sites, the operations team inserts the acl with the address 10.10.0.45 255.255.0.255 (third octet "don't care") for each firewall at each site so that they can make the one update and push to all sites using their firewall management tool.

Hi im facing a problem basically we are replacing our cisco router with asr 1001 for the internet connection.

While creating the PPPOE configuration i noticed that pppoe-client is not working on the interface which im trying to configure for WAN side interface.

I appreciate if someone has experience with regards to this router. and can guide me with the full configuration for pppoe.

Thank you

We have an excel file that we want two computers to have access to. We want both computers to access the actual excel document, not the excel online version.

They don't necessarily have to be able to modify it at the same exact time, just access through excel.

Is there a way to do this with OneDrive? From what I can figure out, OneDrive only works with either both computers using the online version of excel, or one using online version and other the desktop version. Can both computers use the desktop version through OneDrive.

Any help is greatly appreciated!

I need to see the DNS resolution requests of my applications audited and if necessary modified before being sent. I suppose the easiest would be a local resolver that would review my requests before forwarding them to the resolver of my ISP? Another way would be to monitor and be able to override UDP/53 traffi (something I have no clue about). Is there an open source I could use?
Also, I would need this on all OS.
How would you do that? Or would there be a free solution that exists?
Need: support of iDNs as per RFC 5895 for the wole machine (transparent to applications), management of variants, parental control, typos correction. Etc.
Thank you!

Efficient way to get backups off site to Azure

This user guide provides instructions on how to deploy and configure both a StoneFly Scale Out NAS Enterprise Cloud Drive virtual machine and Veeam Cloud Connect in the Microsoft Azure Cloud.

There have been vendors accesses via Rdp & Teamviewer with internal staffs help :
staff use a broadband (Guest network & 4G) to connect their laptop to & their LAN
to the corporate network.

How can I thoroughly trace these down & block them?

Certainly they'll need sort of accounts to login, right?

Hi Experts,

One of my clients asked me to generate a report of the availability of each device in cisco Prime Infrastructure 3.0, using the Device Health report I managed to generate an availability report for the wired network, however the AP availability isn´t generated on this report and I didn´t find another one that shows me the availability for my access points, can someone please tell me how can I generate the mentioned report.

Thanks in advance.

Hi,
As I am new to the Alcatel OmniVista 2500 network management software; I was wondering if anyone may know if the omnivista 2500 supports syslog forwarding? An example is it receives logs from network devices and forward it to an external entity such as SIEM.

Thanks.

I need something to monitor the health of BYOD devices on our network, it needs to be able to quickly scan new devices and check for updated AV, firewall, etc before letting them on the network.  Network Access Protection (NAP) has been discontinued. What are good replacements for NAP?  Is there a built-in monitor in Server 2012 or 2016? Can it be used on 2008 Windows servers?

i have a few racks with (all juniper equipment) virtual chassis inside connected via their management ports to an ex2200 at top of the rack. these ex2200's at the top of the racks all feed back into an ex4300-fibre switch via their ge-0/1/0 sfp slots.
i have used ezsetup to run through initial configurations on them all. the ex4300 is set at 192.168.1.1/24, the racks are setup as 192.168.1.10,11,12.../24. only the default lan has been created for this management.
i am unable to connect to any of the switches via jweb or ssh and they cannot be pinged from anywhere either.
so to recap im using in-band management for the ex2200's and out of band management for the ex3400's via the ex2200's. locally in the racks i can connect to the ex3400 virtual chassis in it via the ex2200.
should the ge-0/1/0 (on the ex2200's) be set as uplink ports, trunks, or simply connected?
should the ge-0/0/x interfaces on the ex4300 be set as trunks or just connected to the downstream switches as is?

Hello All

I require some assistance.
I have a CISCO 880 router (ISO Version 15.2(4)M6) with PPPoE ADSL Internet interface and  VLan1 LAN interface.
Router is up and operational, LAN clients can reach Internet.

I need to enable Port forward from Internet to LAN client web Server, but also retain remote Internet management of router.
I have tried various configs but as soon as I apply policy to Dialer1 interface I loose remote connection to router but port forward to web server works.
Can you assist how I achieve this.

What I need
Internet Public --> to Router (Internet Public or Private 172.16.1.251) IP TCP port Telnet 23 and 22 for management.
Internet Public --> Router Public Internet IP for ICMP
Internet Public --> web server on Private LAN 172.16.1.250 on TCP port 80
Internet Public --> web server on Private LAN 172.16.1.250 on TCP port 23, need to translate TCP Port Internet Public 3023 to Private 23


The current working config, missing above requirements Internet to LAN forwarding.

Hello All
Our core network consists of four Juniper SRX 240h security appliances. They are connected in a ring and use OSPF as the internal routing protocol. On core facing interfaces and ports we use to connect access switches, we have discovered the ‘FIFO errors’ field is incrementing on almost all the interfaces on all four devices. FIFO transmit errors are all 0 but the receive errors value is steadily rising.

After some research online it appears that if the value is not 0, there is most likely an issue with the PIC on the device. As this is happening on all devices it seems unlikely to be a hardware failure but I’m not ruling it out.

Statement from the Juniper website:

•      “FIFO errors—Number of FIFO errors in the receive direction that are reported by the ASIC on the PIC. If this value is ever nonzero, the PIC is probably malfunctioning.”

I’ve also read it is a possible auto negotiation problem on the interfaces. We can see the devices are negotiating the correct duplex and speed settings. On one of the links in the ring, there is no FIFO errors at all on the interface. Also it has auto negotiation setup suggesting to me the problem must be somewhere else.

Example MAC stats output:
  MAC statistics:                      Receive         Transmit
    Total octets                   23084979779      15333372494
    Total packets                     29358714         26257095

Hello, I am preparing  to enable BPDU protection on all my access ports (EX2200 switches ,15.1R5.5).
RSTP is the only protocol used for my topology.
What is the best practice syntax to use?
Do you still need to configure edge ports with junos version 15.1?
BPDU packets need to be enabled on all trunk ports.
Thank you

I need help to troubleshoot a network that goes slowly from time to time, any ideas on the easiest way to find potential issues? I have a Cisco SG300 managed switch in place in case that helps. In some cases I have not been able to ping the server or eve takes a long time to connect to the server via RDP.

I have acquired a new SRX340 to replace an out-of-support SRX240.  Both JUNOS of course.
I had rather expected, perhaps was told, that the configuration of the SRX240 would go straight into the SRX340.
But, naturally, things aren't that simple.

I tried it and got 6 complaints that I don't have on hand right now.

Anway:
I don't want to type in all the lines of code just to see which ones don't work.

So, what would be a good approach to replicate what we have?  Step by step?
I have used both the CLI and the J-Web interfaces, sometimes alternating between them for good results.
But, I'm not so well-versed in the CLI as to take on a project like this wholesale.
And, the SRX340 J-Web interface is quite different.  If it weren't then I might be able to replicate page by page but that seems not likely.

I suppose I could call JTAC for help but I'd rather know what I'm doing first.
My immediate objective is to get the SRX340 on the network (NOT in production) and to be able to configure it remotely thereafter.
But, of course, it has to be in fairly good shape to get that far.
I don't want to just hook it up and hope - even while not in production it would be connected to the network.

The Goal is to Setup a SysLog Server so that a message sent to syslog server with specific  word in it will be archived on a weekly basis.

For this I tried Greylog. I do see the messages coming in but I can't figure out how to automatically extract the message into either a Txt or CSV.

I also skimmed over Splunk but does not seems very intuitive.

Looking for basic features for a small environment.

I'm wondering if anyone might be able to shed some light on how IP addresses are handled..I have a hacker who has compromised my system and I got some info on him (IP addresses and MAC-probably both spoofed)but I'm filing a motion to get the records subpoenaed but I'm noticing m that some are very similar (all same residential hostname) but a little different.
example: 123.456.78.900 then another 123.456.79.009
what is the reasoning behind this?
