OK, this is specifically regarding Cisco Catalyst 2900s, 4500s, and 6500s. I've always matched my interface VLANs to my VLANs.
Lets say I have VLAN 10 on a 2900, and all hosts on it have IP addresses on 192.168.10.0/24. I'd create a VLAN 10 on my 4500 and an Interface VLAN 10 on my 4500, and put my gateway 192.168.10.1 (or whatever) on Interface VLAN 10. Between my 2900 and 4500, i'd trunk VLAN 10 and others. Then all hosts on 192.168.10.0/24 would be able to get to 192.168.10.1 as their gateway.
I just looked at a config for a VLAN I have, and the INT Vlan number containing the gateway does not match the VLAN number.
Example [PC 192.168.20.5/GW 192.168.20.1]<----->[VAL 20 all ports 2900]VLAN20--trunk---VLAN20[int vlan 5 (192.168.20.1)]
Even though the gateway is on an INT Vlan that doesn't match the VLAN, it is still working. I thought the INT VLan# meant that the SVI would be a part of the VLAN#. So, does INT Vlan# not have to match VLAN number?
DOT.TK offers domain with eg : example.tk . In My knowledge there is no one providing .com/.in/.org of free of cost you can host your website in serversfree.com at free of cost which providing 10Gb storage space
You can change which service your domain name uses for its website and email by managing its DNS (Domain Name System) settings. You don't need to know many of the details to use this article, but you can find more information in What is DNS?
Using our DNS Manager, you can change your domain name's DNS settings (stored in something called a zone file). You can use our DNS Manager if:
Your domain name is registered through us and uses our nameservers
Your domain name is registered somewhere else and you set up Off-Site DNS
If your domain name isn't in either of these situations, you can contact the company who controls your domain's nameservers to control its DNS/zone file settings.

I'm switching two win7 pcs from wireless to wired at a friends retail shop. The router's ethernet is connected to other items which he is unsure how they are setup or even what they go to. Strange, and a huge pain. The ethernet cables aren't being used by anything as far as I can tell; possibly ran for future expansion in front room.
Router password isn't default. Without being certain of other network components and settings, I'd rather not reset router.
I added a TP-LINK 5-port gigabit unmanaged switch (what's the difference between a hub and switch?)
I can ping router
When hooking ethernet cable directly to router, I still can't connect to Internet.
I just added a generic 4 port wired hub to a linksys router. I can access the router configuration pages through the hub, but no internet access through the wired connection. Wireless works fine, and hub is obviously connecting to the router. I've done this on my own network many times without any issues, but this problem has me stumped. Any suggestions?
I need some SSH help, from what I can remember, accidently I enabled a cloud feature on my NAS that put all existing files in the following folders, common problem amoungst many;
.wdmc\transcoded_files\944dfee7a3934671a1b910639b68a05a. The only solution is though SSH & delete the folders but keep the files that are hidden in these folders ?
There are some solutions that I've found in my searches, I've been cautious as to if my data in the folders will be deleted.
The price per user decreases as you ramp up, so for 1500 users the cost is $5400 per year.
The LANGuardian is a software based network appliance, fully self-contained, including the operating system, you do not need to provide any software or purchase any other licenses, just a server or virtual machine to install it on. The software updates also include the operating system.
If you download the ISO for example, use the install wizard and install on a spare server or PC with 2 network adapters (one is required for management via the web GUI, second to connect to a SPAN port or port mirror which is configured to monitor the required traffic, VLANs or ports) you can instantly monitor all the machines on your network without installing any agents or client software.
I heard back (by phone none the less) from LanGuardian (netfort.com) and their system runs on RedHat based Linux systems such as CentOS, currently at 6.4, though I imagine it will work just fine with 6.6 (the latest 6.x release). I asked about 7.1 support and they will get back to me with that information. If you want to run it under Windows, you will need to install CentOS in a virtual machine such as VMware or VirtualBox.
My guess is that LanGuardian uses pcap to capture packets in promiscuous mode, and then proprietary software to analyze them (source, destination, content, etc).
I have sent them (NetFort) a request for information as to what platforms they support for hosting servers - Windows-only, or Linux as well since that information is not obviously available on their web site. It is quite pricey - $30USD / year / user. So if you have 500 users, you are looking at a $15,000 / year bill for licensing fees. I will look into open source tools that will effectively do the same and report back here.
One option you have is NetFort LANGuardian. It uses deep packet inspection to monitor what users are doing on a network. You can see how much users are downloading and uploading to/from the Internet. More info at this link
The question on allocating bandwidth is a more tricky one. LANGuardian can send the user an alert if they go over a certain limit. If you want something to take action when a user goes over a certain limit they you probably need to look at an inline device like a firewall with AD integration.
I am looking for a centralized monitoring system for monitor the internet usage of the users in our network. My requirements are, 1. Get the Uploaded & Downloaded MB/GB of each user. 2. Allocate x number of GB for each user for month.
Please give your suggest a software for my requirements.
