# bitbucket key
Host *.bitbucket.org
IdentityFile ~/.ssh/id_rsa.bitbuck

# hostmonsater key
Host *.hostmonster.com
IdentityFile ~/.ssh/id_rsa.hostmonst

# heroku
Host heroku.com
User git
Hostname heroku.com
IdentityFile ~/.ssh/id_rsa.heroku
IdentitiesOnly yes
# end heroku

## NOTE: needed to remove pub-file from .ssh for Heroku to work; not sure why.
## As an opposite case: with bitbucket needed to keep .pub there to work.
