I have been given ssh access to a new Linux server which has nothing more than the LAMP stack installed on it. It's down to me to install things like Drush, phpmyadmin etc and general configuration of the web server.My ssh access is used with a provided username. What I've found is I can't do basic things I've been able to do with a fresh Linux VPS like the following: sudo vim /etc/apache2/sites-available/000-default.conf [sudo] password for axel: Sorry, user axel is not allowed to execute '/usr/bin/vim /etc/apache2/sites-available/000-default.conf' as root on IT-DEV-SERVER.I get similar messages when I try to use drush, drush dl drupal-7.34.PS: Drush was installed via the root user account.Can anyone help by enlightening me on how to grant users the necessary permissions for executing commands?UPDATE:@Arul:I found the following when I execute the visudo command:## This file MUST be edited with the 'visudo' command as root.## Please consider adding local content in /etc/sudoers.d/ instead of# directly modifying this file.## See the man page for details on how to write a sudoers file.#Defaults        env_resetDefaults        mail_badpassDefaults        secure_path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbi$# Host alias specification# User alias specification# Cmnd alias specification# User privilege specificationroot    ALL=(ALL:ALL) ALLrick ALL=(ALL;ALL) ALLowen ALL=(ALL;ALL) ALLaxel ALL=(ALL) ALL# Members of the admin group may gain root privileges%admin ALL=(ALL) ALL# Allow members of group sudo to execute any command%sudo   ALL=(ALL:ALL) ALL# See sudoers(5) for more information on #include directives:#includedir /etc/sudoers.dAxel's ALL settings initially matched Sussies' and Rick's. I adjusted Axel's to match your answer but I still can't execute Drush. I could however use VIM with sudo.
