 Techstaff supports all aspects of technical  needs for the CS department – from top to bottom.  All of us have years of experience in various aspects of technology.  The department itself has centered around Linux and Mac OSX for many years, and these are the operating systems that we currently support.  Our infrastructure consists of almost 400 linux systems (both bare metal and virtual) and about 20 Macs.  The linux systems include all of our central servers, instructional lab machines, instructional resources, and student desktops.  The Macs are used as desktops for staff, faculty, and some students. Techstaff supports all aspects of technical  needs for the CS department – from top to bottom.  All of us have years of experience in various aspects of technology.  The department itself has centered around Linux and Mac OSX for many years, and these are the operating systems that we currently support.  Our infrastructure consists of almost 400 linux systems (both bare metal and virtual) and about 20 Macs.  The linux systems include all of our central servers, instructional lab machines, instructional resources, and student desktops.  The Macs are used as desktops for staff, faculty, and some students.

-[[techstaff:remote_access|Techstaff has seven servers (linux1 through linux7)]] that serve as interactive login systems for instructional use.  These systems are reachable either by the canonical address or by a cname (linux.cs.uchicago.edu).  The address linux.cs.uchicago.edu is a DNS round-robin entry that will rotate between the canonical addresses.  This allows for future expansion of the service.  You should always be aware of the canonical in case you need to reconnect to a specific machine.  The canonical name is displayed in the shell prompt or can be found by typing the 'hostname' command.+[[techstaff:remote_access|Techstaff has eight servers (focal0 through focal7)]] that serve as interactive login systems for instructional use.  These systems are reachable either by the canonical address or by either the alias ''linux.cs.uchicago.edu'' or ''focal.cs.uchicago.edu''.  The address ''linux.cs.uchicago.edu'' is currently an alias for the round-robin DNS round-robin entry ''focal.cs.uchicago.edu'', which rotates through its canonical addresses.  This allows for future expansion of the service, and the ''linux'' alias may change to point to ''jammy.cs.uchicago.edu'' at some point in the future.  You should always be aware of the canonical in case you need to reconnect to a specific machine.  The canonical name is displayed in the shell prompt or can be found by typing the 'hostname' command.
