hey Mariano, damn thing has me stumped. i first under root:
> cp postgresql.conf.sample postgresql.conf > gedit postgresql.conf & where i added the line listen_addresses = '*' > service postgresql-9.1 restart Stopping postgresql-9.1 service: [ OK ] Starting postgresql-9.1 service: [ OK ] then under lucas: > psql prac2 -U lucas -h 127.0.0.1 psql: FATAL: Ident authentication failed for user "lucas" > psql psql: FATAL: database "lucas" does not exist but this works > psql prac2 i did add your lines to pg_hba.conf: # IPv4 local connections: local all postgres ident local all all ident host all all 127.0.0.1/32 md5 host all all ::1/128 md5 host all all 0.0.0.0/0 md5 hostssl all all 0.0.0.0/0 md5 host all all 127.0.0.1/32 md5 hostssl all all 127.0.0.1/32 md5 and after restarting the postgres service, i still get > psql prac2 -U lucas -h 127.0.0.1 psql: FATAL: Ident authentication failed for user "lucas" > psql psql: FATAL: database "lucas" does not exist really really stumped
