Does ‘mac os x sshfs’ exist?

Answer
YES!!!!
Thanks for letting me know!
The project is called MacFuse and its hosted by google code.
For PPC users, there’s a binary, but there are also instructions to build it yourself.

Installation instructions:

$ wget http://macfuse.googlecode.com/files/fuse-binaries-0.1.0b006.tar.bz2
$ sudo tar xjf fuse-binaries-0.1.0b006.tar.bz2 -C /
$ echo "export PATH=$PATH:/usr/local/bin" >> /etc/profile

Mounting goes as follows, make sure that you first create a mount point (empty directory):

$ mkdir -p ~/mnt/host
$ sshfs host:remote_directory ~/mnt/host -oping_diskarb,volname=hostname

The first time you do this, the sshfs command will report something like:

fusefs.kext loaded successfully

That’s it, have fun!
~~Unfortunately not!~~
If it does, please let me know!
Until then, maybe nfs tunneling over ssh would be an alternative?

Need a ‘unit converter’ ?

Bram — Wed, 21 Jun 2006 14:52:51 +0000

Answer: Try units. This is an example of a terminal session using units:

$ units 2084 units, 71 prefixes, 32 nonlinear units You have: 2 inch You want: mm * 50.8 / 0.019685039 You have:

Type help for some help, press ^D to quit units.
Example of usage in a shell script:

# determine installed RAM kbram=`cat /proc/meminfo | awk '/MemTotal/ { print $2 }'` gbram=`units "${kbram} kilobytes" 'gigabytes' |sed --silent -e '1p' | awk '{print $2}'` echo This computer has $gbram Gb of RAM installed!

Can I ’ssh into ubuntu live cd’ ?

Bram — Fri, 26 May 2006 17:59:49 +0000

Answer: Yes you can! But you first need to install the ssh daemon:

ubuntu@ubuntu:~$ sudo apt-get install openssh-server

The server is started automatically after installing. To login remotely, you’ll need to set the password for ubuntu:

ubuntu@ubuntu:~$ sudo passwd ubuntu
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
ubuntu@ubuntu:~$

…or create another user on the system:

ubuntu@ubuntu:~$ sudo adduser brammeleman
Adding user `brammeleman‘…
Adding new group `brammeleman’ (1000).
Adding new user `brammeleman‘ (1000) with group `brammeleman’.
Creating home directory `/home/brammeleman‘.
Copying files from `/etc/skel’
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for brammeleman
Enter the new value, or press ENTER for the default
Full Name []: Brammeleman
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [y/N] y
ubuntu@ubuntu:~$

From another box, you can now login to the system running the live cd. Use the ubuntu username with the password you set or use the newly created account.
