The ITS Team will be performing maintenance on Confluence beginning at 6:00 pm Tuesday, October 8. During this time the service may go offline. It should be available again by 8:00 pm. Please refrain from editing pages during this time to avoid losing your work.
ECE’s Linux servers use Red Hat Enterprise Linux (RHEL) as OS, NIS domain to manage user identity, group and netgroup, SSSD and Kerberos (pam_krb5 module on RHEL7 and older) for authentication against ESERVICES AD, and X2go-Xfce for “remote desktop”. Once an account is created, the user can login using the same UVA password for netbadge or eservices. This way users do not need to remember another set of login & passwords for ECE domain servers.
We have about 40 unix groups on the NIS domain to manage the access to technology PDK tool kits. For some groups, users have will need to get approval from their professors and sign non-disclosure agreement (NDA) before granted group memberships.
X2go is an open source remote desktop software for Linux (similar to the commercial product NoMachine). It runs on Windows, Mac, and Linux to access ECE Linux servers from laptops or desktops. With it you get a Linux desktop environment. The “native” default Red Hat desktop environment GNOME does not work well with x2go and it is memory expensive to run. We use Xfce, which is a light duty desktop environment that is sufficient for ECE’s practice.
