Ssh Console For Mac

The HPCC currently operates two primary clusters, Quanah and Hrothgar. These run the CentOS Linux operating system, but can be accessed from any client using the appropriate tools. Instructions for how to connect to our HPCC clusters depends on the operating system you are using as a client and whether you are attempting to sign in from within or from outside the TTU campus network. Instructions for each of these dependencies can be found below.

Connect from Mac or Linux Using an SSH Client. Your Mac or Linux computer most likely includes an SSH client by default. You can check for an SSH client by typing ssh at the command line. If your computer doesn't recognize the command, the OpenSSH project provides a free implementation of the full suite of SSH. You'll need to get a usb-serial adapter and then connect with a console cable. Adapters aren't very expensive. Connecting to the Console Port with Mac OS X To connect a Mac OS X system USB port to the console using the built-in OS X Terminal utility, follow these steps: Step 1 Use the Finder to go to Applications Utilities Terminal.

Hello - having issues getting SSH to authenticate properly on a Cisco ASA 5500. Below are the respective configs and debug outputs. Any help is appreciated. ///ASA CONFIG # sh run aaa aaa authentication http console LOCAL aaa authentication telnet.
Using the built-in SSH client in Mac OS X. Mac OS X includes a command-line SSH client as part of the operating system. To use it, goto Finder, and selext Go - Utilities from the top menu. Then look for Terminal. Terminal can be used to get a local terminal window, and also supports SSH.
Follow the steps below in order to add your public SSH key: Prepare an SSH key pair for use. To generate a new SSH key pair, you can use PuTTYgen (Windows) or the ssh-keygen command (Linux and Mac OS X). Find instructions on using PuTTYgen and instructions on using ssh-keygen. Log in to the Google Cloud Console and select your project. Navigate to the “Compute Engine - VM Instances.

Logging in to the HPCC Clusters using Windows

If you are connecting to the HPCC Linux clusters from the wired TTU network or the TTUnet wireless network, or if you are connected from off-campus through the TTU Global Protect VPN client, then you are considered to be 'on campus'. Connections made from TTUHSC, the TTUguest wireless network or any other off campus site not in this list are treated as 'off campus'. For off-campus connections, follow the procedures outlined below and then navigate to the off-campus instructions for the SSH gateway at the end of this page.

Getting an SSH client

For users to connect to the HPCC Linux cluster systems they need a Secure Shell (SSH) client. Windows provides an SSH client through its PowerShell window or Command Prompt windows but most Windows users prefer to use one of the following SSH Windows applications. Other available options for plain-text terminals include Termius, which is available for macOS, Windows, Linux, iOS and Android.

Plain-text-only terminal applications:
- Windows Subsystem for Linux (WSL) - Available on Windows 10 only
  - Windows Subsystem for Linux (WSL) is a lightweight Linux client available as an add-in to the Windows 10 operating system.
  - It is turned off by default. To enable it please follow these directions from Microsoft.
  - Once installed, you can continue connecting to our Linux clusters using the 'Logging in to the Linux Clusters using Linux/Mac' section below.
- PuTTY - Available for all version of Windows
  - PuTTY is a lightweight SSH client developed by Simon Tatham.
  - PuTTY can be downloaded (for free) from the PuTTY Website.
X11 graphics-enabled applications:
- MobaXterm is an enhanced terminal application for Windows with X11 server, tabbed SSH client, network tools and more. If you are needing to display X applications from the HPCC system, MobaXterm makes it easier since it does not require additional programs to provide X11 forwarding.

Connecting to HPCC Resources via SSH on Windows

Once you have obtained and installed a suitable SSH client on Windows, please follow the instructions below to make a connection:

Windows Subsystem for Linux (WSL) - Available on Windows 10 only
- Because this method will install a lightweight version of Linux on your system, you can continue connecting to our Linux clusters using the 'Logging in to the Linux Clusters using Linux/Mac' section below, which includes sections on connecting from on campus and from off campus.
PuTTY - Available for all version of Windows
- For instructions on how to connect to the HPCC using PuTTY, please see the following page: 'Connecting to HPCC Systems using Putty on Windows', which includes sections on connecting from on campus and from off campus.
MobaXterm has an extensive help page showing how to connect, including how to set up port forwarding in a way similar to PuTTY for off-campus connections. In general, these are similar to the instructions below.

Logging in to the Linux Clusters using Linux/Mac

If you are connecting to the Linux clusters from the wired TTU network or the TTUnet wireless network, or if you are connected from off-campus through the TTU Global Protect VPN client, then you are considered to be 'on campus'. Connections made from TTUHSC, the TTUguest wireless network or any other off campus site not in this list are treated as 'off campus'. For off-campus connections, follow the procedures outlined below and then navigate to the off-campus instructions for the SSH gateway at the end of this page.

On Macs, the built-in Terminal application can be used for plain-text connections, and XQuartz is the best option for X11 graphics-enabled usage. Linux systems generally include a terminal application and options to install X.org X11 support for graphics-enabled applications.

Other available options for plain-text terminals include Termius, which is available for macOS, Windows, Linux, iOS and Android.

Connecting from 'On Campus' using Linux/Mac

Open a new console/terminal and type in the following:

You will be prompted for your eraider password and once you have entered it you will be logged into Quanah or Hrothgar where you can begin submitting jobs.

Connecting from 'Off Campus' using Linux/Mac, WSL, or other terminal applications:

Ssh Console Mac Os X

If you are connecting to the Linux clusters from the wired TTU network or the TTUnet wireless network, or if you are connected from off-campus through the TTU Global Protect VPN client, then you are considered to be 'on campus'. Connections made from TTUHSC, the TTUguest wireless network or any other off campus site not in this list are treated as 'off campus'. All external traffic to the HPCC servers must first flow through the SSH gateway. You will first need to connect to the SSH gateway and then connect to Quanah or Hrothgar from there. To do this you will need to first open a new console/terminal and type in the following:

You will be prompted for your eraider password, type it in then press enter. Once you have successfully entered your eraider password, the system will respond back with:

You will be prompted for your eraider password and once you have entered it you will be logged into the Quanah or Ivy login node where you can begin submitting jobs.

Ssh Console For Mac Os

If you wish to connect in just one command line through the ssh gateway, please follow the instructions below. The format of this command depends on which version of SSL you are using.

If your setup is using other older versions of SSH, such as built into PuTTY or the current default WSL, connecting in one line from off-site requires the following set of flags:

Ssh Console For Mac Osx

With OpenSSH (used in Linux, Mac, and optionally installable in WSL), you can use the '-J' (jump) flag, as below:

In each case, you will have to enter your eRaider password twice (once for the SSH gateway and once for the cluster login node).

GUI-based SSH applications such as MobaXterm and Termius, include options to allow port forwarding to be set up to use the TTU SSH gateway for off-campus connections. For instructions on how to configure such settings, please consult the help instructions in the web sites for these programs.
