-[[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.
 These systems are configured similarly to the desktops and lab machines and can be used interchangeably with them.  They are configured with 16 hyperthreads, 64GB of RAM, 450GB /local partition, and mount the NFS home directory.
 The purpose of these systems is to support instructional computing.
