Connecting to Sapelo2
Access to Sapelo2 requires an active MyID and password, and two-factor authentication with Archpass Duo. For more details of Archpass Duo, please refer to archpass_duo .
Access to the Sapelo2 is through secure shell (ssh) to the host sapelo2.gacrc.uga.edu . If you have a local system that runs an X Window client or server, you can run X applications remotely.
To connect via ssh, you must have an ssh software and a connection to the UGA campus network. An ssh software is included in recent releases of Unix based operating systems (including Linux and Mac OS X). An SSH Secure Shell Utility is available for Windows on the UGA Sitesoft page (you will need to enter your UGA myID and password to download the software).
Open a connection to Sapelo2
Examples of usage on Unix/Linux/MacOSX
To open a connection to Sapelo2, first open a terminal and at the command prompt type
ssh UGAMyID@sapelo2.gacrc.uga.edu Duo two-factor login for UGAMyID Enter a passcode or select one of the following options: 1. Duo Push to XXX-XXX-4304 2. Phone call to XXX-XXX-4304 3. SMS passcodes to XXX-XXX-4304 Passcode or option (1-3):
or
ssh -X UGAMyID@sapelo2.gacrc.uga.edu
where UGAMyID is your UGA MyID. The -X option might be necessary to allow X windows applications running on the new cluster to be forwarded to your local machine. If your username on your local system is the same as your UGA MyID, you can simply type
ssh sapelo2.gacrc.uga.edu
In order to enable X forwarding from the new cluster to a local Mac OS X machine, the ssh command given above (i.e. ssh -X UGAMyID@sapelo2.gacrc.uga.edu) has to be issued from an X11 terminal (and not from a regular terminal).
To run X Window applications remotely on your local machine
If you have a local machine that runs an X Window client or server, you can forward X Window applications running on the new cluster to your local machine. Recent releases of Unix based operating systems (including Linux and Mac OS X) come with an X windows client. For Windows OS, a free X windows server is Xming. More information on how to install Xming is available on the GACRC FAQ page.
Your ssh may be configured to allow you to run X Window application on your local machine automatically. If it does not, try including the -X flag when connecting to the new cluster (ssh -X UGAMyID@sapelo2.gacrc.uga.edu).
Now you can issue commands to start up X applications on sapelo2.gacrc.uga.edu, such as xterm.
If you plan to run resource consuming X Window applications, such as graphics programs, etc, please use the queueing system to get a command prompt on an interactive node. Information on how to run interactive jobs on the new cluster is at the Running Jobs on Sapelo2 page.
Logging out
To leave the system, be sure that all your open files are closed and all stopped jobs have been terminated then enter:
exit
Connecting to Sapelo
Access to the Sapelo is through secure shell (ssh) to the host IP address 128.192.75.104 (note that connection via telnet is not safe and it is therefore disabled). If you have a local system that runs an X Window client or server, you can run X applications remotely.
To connect via ssh, you must have an ssh software and a connection to the UGA campus network. An ssh software is included in recent releases of Unix based operating systems (including Linux and Mac OS X). An SSH Secure Shell Utility is available for Windows on the UGA Sitesoft page (you will need to enter your UGA myID and password to download the software).
Open a connection to host IP address: 128.192.75.104
Examples of usage on Unix/Linux/MacOSX
To open a connection to 128.192.75.104, first open a terminal and at the command prompt type
ssh UGAMyID@128.192.75.104
or
ssh -X UGAMyID@128.192.75.104
where UGAMyID is your UGA MyID. The -X option might be necessary to allow X windows applications running on the new cluster to be forwarded to your local machine. If your username on your local system is the same as your UGA MyID, you can simply type
ssh 128.192.75.104
In order to enable X forwarding from the new cluster to a local Mac OS X machine, the ssh command given above (i.e. ssh -X UGAMyID@128.192.75.104) has to be issued from an X11 terminal (and not from a regular terminal).
To run X Window applications remotely on your local machine
If you have a local machine that runs an X Window client or server, you can forward X Window applications running on the new cluster to your local machine. Recent releases of Unix based operating systems (including Linux and Mac OS X) come with an X windows client. For Windows OS, a free X windows server is Xming. More information on how to install Xming is available on the GACRC FAQ page.
Your ssh may be configured to allow you to run X Window application on your local machine automatically. If it does not, try including the -X flag when connecting to the new cluster (ssh -X UGAMyID@128.192.75.104).
Now you can issue commands to start up X applications on 128.192.75.104, such as xterm.
If you plan to run resource consuming X Window applications, such as graphics programs, etc, please use the queueing system to get a command prompt on an interactive node. Information on how to run interactive jobs on the new cluster is at the Running Jobs on Sapelo page.
Logging in
When your ssh connection is established, you will be prompted for your UGA MyID password.
Logging out
To leave the system, be sure that all your open files are closed and all stopped jobs have been terminated then enter:
exit
Connecting to zcluster
Access to the Linux cluster (zcluster) is through secure shell (ssh) to zcluster.rcc.uga.edu (note that connection via telnet is not safe and it is therefore disabled). If you have a local system that runs an X Window client or server, you can run X applications remotely.
To connect via ssh, you must have an ssh software and a connection to the UGA campus network. An ssh software is included in recent releases of Unix based operating systems (including Linux and Mac OS X). An SSH Secure Shell Utility is available for Windows on the UGA Sitesoft page (you will need to enter your UGA MyID and password to download the software).
Open a connection to host: zcluster.rcc.uga.edu
Examples of usage on Unix/Linux/MacOSX
To open a connection to zcluster.rcc.uga.edu, first open a terminal and at the command prompt type
ssh username@zcluster.rcc.uga.edu
or
ssh -X username@zcluster.rcc.uga.edu
where username is your username on zcluster. The -X option might be necessary to allow X windows applications running on zcluster to be forwarded to your local machine. If your username on your local system and on the zcluster are the same, you can simply type
ssh zcluster.rcc.uga.edu
In order to enable X forwarding from zcluster to a local Mac OS X machine, the ssh command given above (i.e. ssh -X username@zcluster.rcc.uga.edu) has to be issued from an X11 terminal (and not from a regular terminal).
To run X Window applications remotely on your local machine
If you have a local machine that runs an X Window client or server, you can forward X Window applications running on zcluster to your local machine. Recent releases of Unix based operating systems (including Linux and Mac OS X) come with an X windows client. For Windows OS, a free X windows server is Xming. More information on how to install Xming is available on the GACRC FAQ page.
Your ssh may be configured to allow you to run X Window application on your local machine automatically. If it does not, try including the -X flag when connecting to the zcluster (ssh -X username@zcluster.rcc.uga.edu).
Now you can issue commands to start up X applications on zcluster.rcc.uga.edu, such as xterm.
If you plan to run resource consuming X Window applications, such as graphics programs, etc, please use the queueing system to get a command prompt on an interactive node. Information on how to run interactive jobs on zcluster is at the Running Jobs on zcluster page.
Logging in
When your ssh connection is established, you will be prompted for your zcluster password. The first time you login to zcluster, please change your initial password with the passwd command. This command can be used afterwards as well, to change your password.
Logging out
To leave the system, be sure that all your open files are closed and all stopped jobs have been terminated then enter:
exit
