The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. NTP uses UDP port 123 as its transport layer. It is designed particularly to resist the effects of variable latency (Jitter).

NTP sometimes greatly slows down your Ubuntu’s boot time. To disable it just do a simple code...

This guide shows how to install and configure Smokeping on Ubuntu 9.04 to monitor network latency. SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection.

This article explains how you can set up SSL vhosts under nginx on Ubuntu 11.04 and Debian Squeeze so that you can access the vhost over HTTPS (port 443). SSL is short for Secure Sockets Layer and is a cryptographic protocol that provides security for communications over networks by encrypting segments of network connections at the transport layer end-to-end.

This article explains how you can set up an SSL vhost under Apache2 on Ubuntu 9.10 and Debian Lenny so that you can access the vhost over HTTPS (port 443). SSL is short for Secure Sockets Layer and is a cryptographic protocol that provides security for communications over networks by encrypting segments of network connections at the transport layer end-to-end.

BitTorrent Inc., the company behind the popular BitTorrent peer-to-peer file sharing protocol, has announced that its uTorrent Transport Protocol (uTP) code is now available as open source. The uTP protocol is aimed at maximising network throughput while minimising network congestion, providing a better overall experience for both ISPs and end users.

The latency of the execution of a particular task can be affected by what tasks a system is running, the condition of the network the machine is connected to, and how well the various server machines on the network are performing. LatencyTOP is a command-line tool and kernel patch that lets you see what is causing latency in the applications on your system.

ARP (Address Resolution Protocol) is a protocol used in local area networks (LAN).If a computer needs to send a packet to another machine within the same local network, the IP address and MAC address (Media Access Control) related to the network card on the receiving machine determine the allocation.

The TLS protocol allows client/server applications to communicate across a network in a way designed to prevent eavesdropping, tampering, and message forgery.ProFTPD is a FTP server, it uses only one configuration file "/etc/proftpd.conf"...In this tutorial we will show you how to install ProFTPd +TLS in Ubuntu/debian/linuxmint
