accessing known_hosts file on MAC OS 10.6

Hi, I am fairly new to macs.  I need to edit the known_hosts file and can't find it.  I have tried showing all files by entering this command:  defaults write com.apple.Finder AppleShowAllFiles TRUE
killall finder

I am still not seeing this file anywhere!  Can someone please help!

If you're looking for that file in your .SSH folder you'll not be able to see in the Finder by defaults .. that command you entered DOES NOT reveal system level hidden folders.

Open a Terminal window and enter
cd ~/.ssh

Open in new window

then enter
ls -al

Open in new window


If the known_hosts file exists youll see it there ... you can then open it in the terminal editor as follows
pico known_hosts

Open in new window


Alternatively in the Finder .. in the Go menu select 'Go to Folder'.  Then paste in the path
~/.ssh

Open in new window

It will open the Folder in the Finder
You can see the file if it is in there ... and open with a program like TextWrangler an excellent text editor FREE for OSX .. http://www.barebones.com/products/textwrangler/

On the POSIX (unix/linux/osx) filesystem, any file preceded with a . (dot) is "hidden"  you can always navigate to them and you can also view them on the terminal command line with -a option. (e.g. ls -a or ls -la.

If you want to open them in the finder, go to the command line and type open ~/.ssh if you're not in your home folder or open .ssh if you are.

If you're removing hosts from the file, then you can just run the following on the command line
ssh-keygen -R HOSTNAME

You can search for a hostname with
ssh-keygen -F HOSTNAME

You normally let ssh prompt you to add host keys, but if you have a file, you can append it to known_hosts.  I frequently  generate a list of known host keys for users to check against or insert into their own known_hosts file.

cat MY_HOST_KEY >> ~/.ssh/known_hosts
cat MY_HOST_KEY_LIST >> ~/.ssh/known_hosts
