Portland Linux / Unix Group

Welcome to PLUG Celebrating over 25 years of Portland's best technical dialog The Portland Linux/Unix Group (PLUG) is a group of enthusiasts dedicated to teaching and learning about Linux, Unix and related freedom-producing technologies. There is no membership fee to join and we welcome people of all levels of experience. PLUG has met since 1994 and hosts a monthly General meeting and a hands-on support Clinic. All in-person events are on hold until further notice. PLUG is open to everyone but does not tolerate abusive behavior on its mailing lists or at its meetings. PLUG Mailing Lists, IRC and Twitter Between meetings, we converse on a number of mailing lists and IRC:
