-These pages have information on the computing services provided by the UVA Computer Science Department. There are also answers to the most common issues you may experience+These pages have information on the computing services ​and [[compute_resources|resources]] ​provided by the UVA Computer Science Department.
  
-//This website has two parts. Computer Science ​Computing ​Information provides information about the resources ​available to you in the CS Dept. The "​Restricted Staff Information"​ section is for system staff only. Your CS computing account ​is for access to servers and other computing resourcesyou do //NOT// log in to this website//+Computing ​services and resources ​are accessed via a CS Dept computing account. Faculty and graduate students have accounts created ​for themundergraduates majoring ​in CS or taking CS courses can request a CS account.
  
-When you start at UVA, you get a userid (something like "//​abc1de//"​),​ which you use to access general UVA sites like Collab or Netbadge systems. When you get a CS Dept. account, you will have an identical userid ("//​abc1de//"​),​ //but a different password than the one you use for general UVA systems//. **When the CS account is created for you, you are sent an email with a temporary password that needs to be changed upon first login.** See //New Account Information//​ below.+When you start at UVA, you get a userid (something like "//​abc1de//"​),​ which you use to access general UVA sites like Collab or Netbadge systems. When you get a CS Dept. account, you will have an identical userid ("//​abc1de//"​),​ //but a different password than the one you use for general UVA systems//. **When the CS account is created for you, you are sent an email with a temporary password that needs to be changed upon first login.** See //Account Information//​ below.
  
-==== New Account Information ==== 
- 
----- 
-Welcome! ​ Your account for the Computer Science network has been created, and you have been emailed the account information.  ​ 
- 
-This account is for logging into servers and desktops within the CS Dept. It is NOT for CS websites or general UVA systems like Collab or other general UVA systems. Even though your user id is the same as your NetBadge user id used for UVA systems, //your CS account password is only for CS Dept. systems//. 
- 
-You have been issued a temporary password, so the first time you log in you will be asked to set a new password. The easiest way to change your temporary password is to open a “terminal” window on your laptop or desktop, and use //ssh// to //​portal.cs.virginia.edu//,​ for example “''//​ssh abc1de@portal.cs.virginia.edu//''​”. You will then be asked for a new password, which you should set to a password you typically use. You will then use this password to login to all CS network systems. See [[linux_ssh_access|Linux SSH Access]] for more information. 
- 
-Note: if you want to use the NX/​Nomachine cluster to get a graphical desktop (see: [[nx_lab|NX Linux Remote Desktop Cluster]]) you should FIRST login to //portal// to change your temporary password. NX will not let you login with that temporary password. 
- 
-If you set your CS password, then forget it, you can reset it below. 
- 
-== Regular accounts vs. mysql accounts == 
-Please view this video for important information about mysql accounts. One thing not mentioned in the video is that your regular account and your mysql account are two different accounts with two different initial passwords, keep that in mind!

This includes desktop, printer, and server support, as well as laptop loaner and other support. Your patience during this extraordinary period is appreciated.+Computing Support personnel ​will resume in-person support starting August 2nd, 2021.

-**CS Firewall** We are blocking ​SSH connection attempts ​from outside of the UVA network, with one exception. You are not able to SSH directly into CS hosts from outside of UVA, except for connections to ''​%%portal.cs.virginia.edu%%'',​ from which you can ssh to other CS servers. See [[linux_ssh_access|here]] for more information.

-==== Accounts ==== +New accounts are assigned ​temporary password, so the first time you log in you will be asked to set a new passwordThe ONLY way to change your temporary password ​is to open “terminal” window on your laptop or desktop, and use //ssh// to //​portal.cs.virginia.edu//,​ for example “''//​ssh abc1de@portal.cs.virginia.edu//''​”.

See [[linux_ssh_access|Linux SSH Access]] for more information. You cannot use the Password Reset tool link above to change your temporary password.
-When you receive ​Computer Science user account ​you get an account that allows ​you to login to Windows or Linux systems in the CS DeptThis is a unique account, and should not be confused with the accounts ​you use to login to NetBadge, Collab, SIS or other UVA systems. ​+
  
-Your userid is identical ​to your UVA "​NetBadge"​ useridbut your password ​is differentWhen your account is setup, you will receive an email with your account information.+Note: if you want to use a Linux remote desktop(see: [[nx_lab|NX Linux Remote Desktop Sessions]]) you should FIRST login to //portal// to change ​your temporary ​password. ​The Linux remote desktop system ​will not let you login with that temporary password.
  
-  * [[Accounts_Password|How do I change my CS password?]]+If you forget your CS password you can reset it using the [[https://​www.cs.virginia.edu/​PasswordReset|Password Reset Tool]].
  
 Upon separation from UVA CS, your account will be closed one month after that separation, and your home directory will be removed. No backup will be provided, so it is important for you to save any files you wish to take with you onto other storage. Upon separation from UVA CS, your account will be closed one month after that separation, and your home directory will be removed.

 ==== Using the CS Dept computing environment ==== ==== Using the CS Dept computing environment ====
  
-The CS Dept provides extensive computing resources ​running on its own wired network. The wireless network ​is managed by the main UVA Information Technology Service (ITS)Systems with wired connections to the CS Dept network need to be registered with the Dept for the device to get an IP address and thus connect to the network and internet. This is done by sending the device'​s MAC address to cshelpdesk@virginia.edu, and including the system'​s name.+The CS Dept provides extensive computing resources. The entry point these resources ​is the [[compute_portal|portal]] cluster, a load balanced cluster of systems providing general purpose computingFrom portal, [[compute_resources|other servers are available]] that have GPU accelerators,​ large memory sizes, and large core counts.
