SYSLOG SERVER/ANALYSIS
In a word: Splunk
it may be overkill, and it takes a little configuration to get going, but it does near-real time analysis and reporting any any number of log files from any number of systems. It's free for small volume (up to 500MB per day), but can run into some serious $$ if you're dealing with lots of logs (e.g. hundreds of GB per day)
LOAD TESTING A WEBSITE?:
There are sites that can do this, but I wouldn't worry about it. Your server is not going to be your limit, it's far more likely to be your network bandwidth. Any Mac Mini is more than capable of saturating most internet links, unless you're in a commercial datacenter with gigabit uplinks to your upstream providers.
I know there is a Mac OS X app that can test and map ones network, complete with graphical maps showing where each machine and server is located in the building
I'm not aware of any app that can build a physical map of your network, since that requires an understanding of building layouts, etc., but logical maps (a list of all the devices on the network, switch ports, etc.) are easy enough. Intermapper is probably a good starting point.
- I have many devices from which I want to get logs using a syslog server hosted on my iMac. To get in touch with logs and analyse them, I am looking for a good syslog viewer for mac which have the following functionalities: color log by level; stats & graphs; send mail and alert.
- Syslog servers can also have automated events to trigger alerts that help to prevent downtime or outages. Here is a list of a few Windows-based Syslog servers: 1. Kiwi Syslog Server. This server is simple to install and generates reports in plain text or HTML. The software handles Syslog and SNMP, even from Linux and UNIX hosts.
- Setting up syslog to log remotely is simple. On the system for which you want to receive the log entries, configure syslog to start with the -r option, which enables it to receive remote log.
- The built-in syslog server in EventLog Analyzer collects syslogs from network devices and provides in-depth insights into security events. Managing syslogs using EventLog Analyzer's syslog server. EventLog Analyzer's built-in syslog server: Supports macOS, Linux, and Unix devices. Helps collect, view, and archive syslogs.
To begin setting up a Syslog server on the Meraki dashboard, first, navigate to Network-Wide Configure General. Here you will see a section for Reporting, with the option for Syslog server configurations. Click on the Add a syslog server link to define a new server. Configure an IP address of your syslog server, the UDP port the server is.

MAC address
A Media Access Control (MAC) address is a 48-bit (6 bytes) address that is used for communication between two hosts in an Ethernet environment. It is a hardware address, which means that it is stored in the firmware of the network card.
Every network card manufacturer gets a universally unique 3-byte code called the Organizationally Unique Identifier (OUI). Manufacturers agree to give all NICs a MAC address that begins with the assigned OUI. The manufacturer then assigns a unique value for the last 3 bytes, which ensures that every MAC address is globaly unique.
MAC addresses are usually written in the form of 12 hexadecimal digits. For example, consider the following MAC address:
Every hexadecimal character represents 4 bits, so the first six hexadecimal characters represent the vendor (Hewlett Packard in this case).
How to find out your own MAC address?
If you are using Windows, start the Command Prompt (Start – Programs – Accessories – Command Prompt). Type the ipconfig/all command and you should see a field called Physical Address under the Ethernet adapter settings:
If you are using Linux, type the ifconfig command. You should see your MAC address referred to as HWaddress.

IP address
An IP address is a 32-bit number that identifies a host on a network. Each device that wants to communicate with other devices on a TCP/IP network needs to have an IP address configured. For example, in order to access the Internet, your computer will need to have an IP address assigned (usually obtained by your router from the ISP).
An IP address is usually written in the form of four decimal numbers seperated by periods (e.g. 10.0.50.1). The first part of the address represents the network the device is on (e.g. 10.0.0.0), while the second part of the address identifies the host device (e.g. 10.0.50.1).
In contrast to MAC address, an IP address is a logical address. It can be configured manually or it can be obtained from a DHCP server.
The term IP address is usually used for IPv4, which is the fourth version of the IP protocol. A newer version exists, IPv6, and uses 128-bit addressing.
Private IP addresses
There are three ranges of addresses that can be used in a private network (e.g. your home LAN). These addresses are not routable through the Internet.
Private addresses ranges are:
- 10.0.0.0 – 10.255.255.255
- 172.16.0.0 – 172.31.255.255
- 192.168.0.0 – 192.168.255.255
