 =====What=====
 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.

 ======Resources======
 All CS systems that permit logins require SSH over the standard port (22) and use your CNetID for authentication.
+*//ITS will begin blocking SSH to the campus on Oct 13, 2021.  SSH access will require use of ITS' VPN to access SSH within the campus network.  This will certainly affect desktops, but CS has requested exemptions for subnets with research and instructional servers.//
 =====Your CS Account=====
 Your CS account name will be the same as your CNetID, however it is a different account.  It does share the same authentication method, so the password remains the same.  You must have a CS account in order to use CS services.  If it is not automatically provisioned for you you, you can request it by contacting Techstaff.

 =====Services=====
 ====Interactive login servers====
-[[techstaff:remote_access|Techstaff has 5 servers (linux1 through linux5)]] 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 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.
 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.
