  2. How can I login to my KITP account from home to transfer files?

  4. I want to conect my laptop to the KITP network. What is the TCP/IP configuration?

3.1. I cannot login to the KITP throught telnet or SSH. What am I doing wrong?
Due to security issues in telnet and ssh1, we have installed the “safer” ssh2 (secure shell).

For instance, if your account name were bsmith, and the computer you wished to connect to were breeland, you would type
ssh bsmith@breeland
or
ssh bsmith@breeland.kitp.ucsb.edu

At some point in the logon, you are told

Host key not found from the list of known hosts.
Are you sure you want to continue connecting?

To this you should answer “yes”. Please note that simply entering ‘y’ is not good enough! You must enter the whole word “yes”.

For email purposes, we recommend you ssh to breeland. There are, however, other computers which are available for ssh access. Please see a system administrator, or email the KITP Helpdesk, for other available computers.

The procedure for using ssh from unix is:

ssh username@computer

ssh bsmith@breeland

ssh bsmith@breeland.kitp.ucsb.edu

Host key not found from the list of known hosts.
Are you sure you want to continue connecting? [yes/no]

3.2. How can I login to my KITP account from home to transfer files?
Use SSH to connect to KITP. You can do so by typing ssh breeland.kitp.ucsb.edu. From there
you can either ftp out, or use scp.

For example, if user bsmith is on breeland.kitp.ucsb.edu and wants to copy some files to a directory called astrot in his account on a computer called physics.ucla.edu, he would enter the following:

scp file1.txt file2.txt bsmith@physics.ucla.edu:astrot



Likewise, if he wanted to copy the entire contents of the astrot directory on physics.ucla.edu back to his breeland.kitp.ucsb.edu account, he would enter:

scp -r bsmith@physics.ucla.edu:astrot astrot
ssh breeland.kitp.ucsb.edu

scp file1.txt file2.txt bsmith@physics.ucla.edu:astrot

scp -r bsmith@physics.ucla.edu:astrot astrot

3.3. Is there dialup PPP access to KITP?

Ask the KITP Helpdesk to setup a PPP account for you on the KITP modems. Do the same thing to obtain the dial-in phone number . Use your current Unix username and password to get in. For Win95/98 and Mac computers the setup is straightforward. If you have a Linux box, or special dialup software, you might be asked for a port password after dialing up. If this is the case, contact the helpdesk, and they'll drop by with the password.

3.4. I want to connect my laptop to the KITP network. What is the TCP/IP configuration?
