betweenGo

Sometimes customers want to see my name on the invoice, sometimes they only want to see betweenGo.

To change it, go to Company > Company Information… and change the Company Name field (either “Frank S. Kim” or “betweenGo”).

When I get someone’s Eclipse project I always ended up recreating the project. Now I won’t need to do that anymore since I learned about the Import feature.

1. Go to File > Import…
2. Select Existing Projects into Workspace
3. Select the root directory of the project
4. Press Finish and watch Eclipse wonderfully recreate the project.

To implement RSA authentication under ssh so that the user is not continually asked prompted for a remote-host password when using ssh, scp, or any programs using ssh underneath such as cvs and svn do the following.

1. Create a public/private RSA key pair. This will be used for RSA authentication. When generating this RSA key pair don’t enter a passphrase otherwise you will always be prompted for it.

   $ ssh-keygen -t rsa
   Generating public/private rsa key pair.
   Enter file in which to save the key (/home/fkim/.ssh/id_rsa):
   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   Your identification has been saved in /home/fkim/.ssh/id_rsa.
   Your public key has been saved in /home/fkim/.ssh/id_rsa.pub.
   The key fingerprint is:
   2a:59:54:3f:82:8f:79:92:1d:39:7b:62:02:68:97:e6 fkim@paltp1235
   
   $ cd .ssh
   $ chmod 400 id_rsa id_rsa.pub

2. Copy the public RSA key to the remote host.

   $ scp -p ~/.ssh/id_rsa.pub  fkim@betweengo.com:~/
   Password:
   id_rsa.pub                                    100%  396     0.4KB/s   00:00

3. ssh to the remote host and create an .ssh directory if it does not already exist.

   $ ssh fkim@betweengo.com
   Password:
   [box ~]$ mkdir .ssh
   [box ~]$ chmod 755 .ssh

4. Append the public RSA key to the list of authorized keys.

   [box ~]$ cat id_rsa.pub >> .ssh/authorized_keys2
   [box ~]$ chmod 644 .ssh/authorized_keys2

5. Log out and log back in to verify that you no longer need to enter your password.

   $ ssh fkim@betweengo.com
   [box ~]$

Note if this does not work it is sometimes because the ssh client cannot find the id_rsa file. It looks for it normally where it keeps the known hosts file. On most systems this is the default location for where it writes the id_rsa file. On one system I found that it was looking for the id_rsa file in C:\.ssh.

In some cases RSA authentication will not work and you will need to use DSA authentication. This article, SSH Logins Without Providing A Password, gives a good description of how to do this. The instructions are quite similar.
