I run Apache and IIS on Windows and prefer a server switching method so only one application listens on port 80 at any time. Who can you call when Apache wonвЂ™t start because port 80 is blocked?ДЄpologies for not writing a typical web development post but this is exactly the problem I encountered and it seems many others have too. Clients will call you the second their email fails (they forgot to switch on their router) or their website breaks (theyвЂ™re using IE5.0). If only clients realized the hassles developers encounter with their OS. If youвЂ™re keen to learn more about using Apache, you may find this more recent article on launching a VM with Apache CloudStack of great interest. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.ДЇor more detailed and personalized help please use our forums.This article was written in 2011 and remains one of our most popular posts. This can be accomplished in both Windows command prompt and Linux variants using the 'netstat -aon' command. When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. UDP is often used with time-sensitiveДЄpplications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data. The message to process any errors and verify correct delivery. Like TCP, UDP is used in combination with IP (the Internet Protocol)ДЄnd facilitates the transmission of datagrams from one computer to applications on another computer,Д«ut unlike TCP, UDP is connectionless and does not guarantee reliable communication it's up to the application that received Guaranteed communication/delivery is the key difference between TCP and UDP. TCP guarantees delivery of dataДЄnd that packets will be delivered in the same order in which they were sent. To establish a connection and exchange streams of data. TCP ports use the Transmission Control Protocol, the most commonly used protocol Used port numbers for well-known internet services.

IANA is responsible for internet protocol resources, including the registration of commonly Ports are unsigned 16-bit integers (0-65535) that identifyДЄ specific process, or network service. Port numbers in computer networking represent communication endpoints. Microsoft Point-to-Point Tunneling Protocol (PPTP) (official)

The PPTP implementation in Cisco IOS 12.2 and 15.0 through 15.3, when NAT is used, allows remote attackers to cause a denial of service (device reload) via crafted TCP port-1723 packets, aka Bug ID CSCtq14817. SMC Networks Barricade Wireless Cable/DSL Broadband Router SMC7004VWBR allows remote attackers to cause a denial of service via certain packets to PPTP port 1723 on the internal interface. The Siemens Gigaset SE361 WLAN router allows remote attackers to cause a denial of service (device reboot) via a flood of crafted TCP packets to port 1723.

Mac OS X Server VPN service also uses port 1723 (TCP).

It can also use 1194/UDP (OpenVPN), and a number of other ports, as follows: 80,8081/TCP (web server), 443,8080/TCP (web admin), 20,21,22/TCP (FTP/SSH), 13131/TCP (telnet), 873,8899/TCP (remote replication), 20001/UDP (CloudLink - optional, only required for access without manual port forwarding) QNAP NAS uses port 1723/TCP for PPTP VPN. OpenVPN with AES encryption is a much more secure choice. an attacker can modify PPTP packets without possibility of detection.

PPTP is also vulnerable to bit-flipping attacks, i.e.

It is prone to MITM (man in the middle) attacks, where an attacker can capture the handshake and do an offline attack to derive the RC4 key and decrypt the traffic. It is no longer considered secure, as cracking the initial MS-CHAPv2 authentication can be reduced to the difficulty of cracking a single DES 56-bit key, which can be brute-forced in a short period of time. PPTP has a number of known vulnerabilities. PPTP VPN (Point-to-Point Tunneling Protocol Virtual Private Networking).
