17 # * checked out from svn then removed it (as to get my password on there)
18 # * change /etc/passwd so that /bin/bash is the default shell
19 # * added "PermitUserEnvironment yes" to /etc/ssh/sshd_config
20 # * svcadm restart ssh
21 # * created /.ssh/environment
22 # -- PATH=/opt/csw/bin:/usr/bin:/usr/sbin
