System Access
SSH AccessNote: Access to our systems is likely to change in coming months, as we are extending and re-structuring our resources. Please revisit this page occasionally to stay abreast with any changes. The standard way to access our resources is through ssh. For security reasons, all access is indirect through the login node sflogin0 (sfnode0). The IP address for this (Solaris) login node is 130.15.59.64, the node name is sfnode0.hpcvl.queensu.ca:
$ ssh -X hpcXXXX@sfnode0.hpcvl.queensu.ca

This is sflogin0, a dedicated login host on the HPCVL grid
SunFire E2900, 24 x 1.8 GHz UltraSPARC-IV+, 192 GB RAM

hpcXXXX@sflogin0$
The first time you connect to a new system using SSH, your client will ask you something along the lines of: "do you want to connect to a system with host key fingerprint xxxxxxxx?". Pick/type "yes" to continue connecting. Make sure X-forwarding is enabled, either by using the -X option in the ssh command, or including it in the default settings of the ssh client. This is necessary if you want to use any software with a graphics component. You will need your username and your system access password to get in (here, we use hpcXXXX). Important : sflogin0 only serves as a first point of access. For workup purposes and job submission, you need to access other nodes, especially the Linux login/workup node swlogin1. This requires typing your password again: hpcXXXX@sflogin0$ ssh swlogin1 hpcXXXX@swlogin1's password: hpcXXXX@swlogin1$ Linux and Mac systems have an ssh client installed by default and don't require a special setup for this to work. On Windows systems, we suggest using MobaXterm, which is free for individual usage and has many useful features (such as an Xserver client, file transfer tool, and even a local "bash shell") built in. Note for Mac UsersIf you are using a Mac to login to our systems through ssh you may have to install XQuartz X11 Support on your computer. This is necessary to enable the display of graphics that was generated on a Unix server. Unfortunately, newer versions of OSX don't come with native X11-Windows support. |
