Secure Login (https://phas.ubc.ca/secure-login)
Logging onto PHAS Servers Securely
Secure logins refer to methodologies that allow secure data transfer over insecure networks. In particular, you do not want your passwords sent over a network in plaintext. The ssh protocol uses public-key cryptography to verify the authenticity of a remote host & to safeguard the data transferred between the remote host & a local client. There are 2 commonly used client applications:
- ssh a replacement for the telnet command, allows terminal access to a remote computer.
- scp secure copy allows the copying of files to/from a remote host
The department's login hosts ( ssh.phas.ubc.ca & ssh2.phas.ubc.ca) allow ssh connections from anywhere.
- For general SSH and sFTP access use PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/) or MobaXterm (http://www.phas.ubc.ca/~hongyun/MobaXterm_v7.1.zip).
- Xming (http://www.straightrunning.com/XmingNotes/) is a port of the X Window System to the Microsoft Windows; in particular it provides a X11 server. This allows you to run a X11 application on a remote server and have the display on the local Windows system.
- For transferring files securely from a Windows-based PC, we recommend FileZilla (http://prdownloads.sourceforge.net/filezilla/FileZilla_2_2_9_setup.exe?download).
Mac OS X now include command line SSH and SCP.
- On Mac OS X 10.3 Panther and Mac OS X 10.4 Tiger, X11 (XFree86 X11R6.8) is available as an optional install from installation disks.
- Latter versions of Mac OS use an X11 implementation based on X.org
Linux and Unix Computers
- All major distributions now include command line SSH and SCP.
