Consequently, high profile systems run on VMS since built with security from the ground up. Despite the operating system being over 30 years old, there's never been a known instance of a VMS hack or a VMS virus. With advanced descriptions, add the /FULL qualifier, like so: $ SHOW DEVICES /FULL EWįor just one device, say EWA0: $ SHOW DEVICE /FULL EWA0Īlternatively, this also works: $ TCPIP SHOW INTERFACES /FULL $ TCPIP IFCONFIG -A OpenVMS/VMS $ TCPIP TRACEROUTE GOOGLE.COM ! idem dittoĪll the ethernet adapters should typically be listed as EW* devices, which can be found by typing: $ SHOW DEVICES EW In the case that you want to output more than one password, simple change the value 1 to any other number, for example 3, to receive three generated passwords: #COMMANDES PWGEN PASSWORD#The result will now be a single password that has 20 characters: In the case that you want a password that is a different amount of characters, such as rather 20 (or any other number), you can modify the amount of characters output such as in this example to output a 20-character long random password: Note the inclusion of special characters suchas # or +: To make your passwords more secure, you can add special characters using the flag -y as part of the above command such as this:Īdding the special character flag creates passwords like this instead of the above. This command results in a password that looks like this: The -s flag ensures that the password created is truly random, the value 10 states how many characters long the password should be, and the value 1 represents the number of passwords we want to output: To create a single random password that is ten characters (uppercase/lowercase letters and numbers), execute this command. When using pwgen, the basic structure of the command is as following: #COMMANDES PWGEN INSTALL#To install pwgen for yourself, execute one of the following commands for your respective system (you may need root privileges, use sudo if needed): #COMMANDES PWGEN FREE#It is open-source, free to use, and works on many systems. #COMMANDES PWGEN GENERATOR#pwgen is more than a random password generator however, it is a professional password generating tool that can create classical cryptographically-secure passwords, pattern-based passwords, list-based passwords, and more, all using the random pool technique to generate random data. While /dev/urandom can be used anywhere and comes built-in, you can also use pwgen to generate a random password. Head /dev/urandom | tr -dc A-Za-z0-9 | head -c 10 Using pwgen To get a password that is longer than eight characters, simply change the value of -c 8 in the above command to your desired length, for example the following for a ten-character long password: The final pipe again uses head to cut the output into eight characters. We used the options -dc to delete and use the complement of the given set with A-Za-z0-9 to get uppercase, lowercase, and numerical characters. This command translates the input string into a new one based on the options given to it. The above command, broken down, uses the head to get the first few lines of the dev/urandom file, then pipes the output to the command tr. Head /dev/urandom | tr -dc A-Za-z0-9 | head -c 8 We can use /dev/urandom to generate a password that is eight characters long and is made up of random uppercase and lowercase letters and numbers (you may need to use sudo): Note that this is different than the popular /dev/random that you likely know already, which is a true random number generator unlike the pseudo-randomness of /dev/urandom. The below command uses /dev/urandom, which is a special file that uses the internal random number generator to produce pseudo-random bits. We start off simple with a method that can be used on any Linux/Unix system in order to generate a random string.
