Hi Aaron, and thank you for the quick reply.
> What OS/distro are you running? Centos 6.7 > Are you using Apache, Nginx or something else to serve up RT? Apache/2.2.15 (CentOS) Server at localhost Port 80 > Have you checked that DNS is resolving properly on your machine? Yes, DNS is warking properly and very fast. However, on my test VMs I have used only IPs to avoid putting the DNS into the equation. > Are commands you run from the shell taking a long time to run, or is it just RT? Apparently it is just RT Thank you! Cris Cristiano Guadagnino Servizio Sistemi Dipartimentali, Periferici e DB _______________________________ Bankadati Servizi Informatici Soc.Cons.P.A.
