In order to access frack hosts (such as frdev1001) you must have a proper ssh config. To edit it in OSX, open a terminal and type:
open -a TextEdit ~/.ssh/config
The file should look more or less like this:
Host tellurium.wikimedia.org User your_username_here IdentitiesOnly yes IdentityFile ~/.ssh/id_rsa ProxyCommand none Host *.frack.* frdev1* User your_username_here IdentitiesOnly yes IdentityFile ~/.ssh/id_rsa ProxyCommand ssh -a -W %h:%p tellurium.wikimedia.org
Make it so, and save. The name of "id_rsa" may vary.
