SSH and Connecting to the Ibnsina from AUB:
ssh (SSH client) is a program for logging into a remote machine and for
executing commands on a remote machine. It is intended to replace rlogin
and rsh, and provide secure encrypted communications between two
untrusted hosts over an insecure network.
- If you are using a Linux/Unix client, the following is recommended:
- If ssh is not installed, the files are availalbe at openssh.org
- Given the ssh client is installed on your client, type:
"ssh ibnsina.cams.aub.edu.lb -l yourusername"
- You will be prompted for your password, after that you will have established a secure connection with the cluster
- If you are using a Windows client, the following is recommended:
- Download and use Putty which is a free ssh client.
- Given the ssh client is installed, do the following:
Type "ibnsina.cams.aub.edu.lb" in the "Host Name" field.
- Click on the "SSH" radio button in "Protocols"
- You will be prompted for your password, after that you will have established a secure connection with the cluster
Transfering Files To and From the Cluster
scp copies files between hosts on a network, and comes with installed with ssh. If not the files are availalbe at openssh.org
It uses ssh for data transfer, and uses the same authentication and provides the same security
as ssh. Unlike rcp, scp will ask for passwords or passphrases if they are needed for authentication.
- On a Unix/linux machine:
We assume you are logged on to your personal computer:
("~" is equivalent to your home directory "/home/yourname")
scp file1.c yourname@ibnsina.cams.aub.edu.lb:~/work/
(copies file1.c TO your ibnsina directory "work")
scp -r ./folder1/ yourname@ibnsina.cams.aub.edu.lb:~/work/
(recursively copies folder "folder1" TO your ibnsina directory "work")
If you are ON ibnsina.cams.aub.edu.lb, the syntax is the same but instead of "ibnsina.cams.aub.edu.lb:"
above you would type "yourcomputername".
- On Windows machine:
- PSCP can be used to copy files securely from the windows terminal
- Some people find it easier to work with a graphical interface instead of the command-line pscp command. Another possibility in this case is to use a free program called WinSCP
