Your network design is the greatest factor for poor wireless roaming. To get the best results, you will need to tune your wireless home network. This includes accounting for neighboring networks, interference, the density of your APs, the number of your wireless clients and their idiosyncrasies in terms of wireless standards support. Don’t expect to deploy a multi-AP network in your home, leave everything at the default settings, and have it work flawlessly. The location, power settings, and additional configuration parameters of your AP’s are critical.UniFi wifi networking
In the Admin UI under “Authentication" it is possible to select one of 4 methods for authenticating user credentials; LOCAL, PAM, RADIUS or RADIUS. This can be done by changing the configuration key
auth.module.type. This configuration key is not optional and is by default set to PAM. With LDAP and RADIUS additional settings are required to be able to authenticate users, for example which server to contact and any required shared secret code to be able to access the external authentication backend.
In this post, I discuss and give an example of how to use Squid, a leading open-source proxy, to implement a “transparent proxy” that can restrict both HTTP and HTTPS outbound traffic to a given set of Internet domains, while being fully transparent for instances in the private subnet.tutorial aws networking squid
If the router is filtering too, ubuntu has to be aware of the gateway's existence for both interfaces and use
rule settings for a correct routing.
Normally, a Linux system only has one routing table, in which only one default gateway can make entries. With iproute2, you have the ability to setup an additional routing table, for one thing, and allow this table to be used by the system based on rules, for another.linux networking homelab

Start the capture with
netsh trace start capture=yes tracefile=foo.etl Stop the capture with
netsh trace stop. Two files are created:
foo.etl. These files can be opened with Microsoft Message Analyzer. Once the file has been loaded into Message Analyzer you can export it to pcap to view in Wireshark.
Iptables places rules into predefined chains -
FORWARD - that are checked against any network traffic relevant to those chains and a decision is made about what to do with each packet based upon the outcome of those rules. These actions are referred to as targets, of which the two most common predefined targets are
INPUT- All packets destined for the host computer.
OUTPUT- All packets originating from the host computer.
FORWARD- All packets neither destined for nor originating from the host computer, but passing through (routed by) the host computer. This chain is used if you are using your computer as a router.
The network stack does several seemingly-impossible things. It does reliable transmission over our unreliable networks, usually without any detectable hiccups. It adapts smoothly to network congestion. It provides addressing to billions of active nodes. It routes packets around damaged network infrastructure, reassembling them in the correct order on the other side even if they arrived out of order. It accommodates esoteric analog hardware needs, like balancing the charge on the two ends of an Ethernet cable. This all works so well that users never hear of it, and even most programmers don't know how it works.read later networking
RRDtool refers to Round Robin Database tool. Round robin is a technique that works with a fixed amount of data, and a pointer to the current element. Think of a circle with some dots plotted on the edge. These dots are the places where data can be stored. Draw an arrow from the center of the circle to one of the dots; this is the pointer. When the current data is read or written, the pointer moves to the next element. As we are on a circle there is neither a beginning nor an end, you can go on and on and on. After a while, all the available places will be used and the process automatically reuses old locations.tutorial sysadmin networking rrdtool
