SSH Issues

Can't login / asking for password

---

Try the following:

-Check to see if you are able to ssh into the dzdb gateway (dzdbgw) first

-Contact a systems administrator and check to see if your ssh key has been added/exists.

-Remove old host key on your machine then try to ssh in

ssh-keygen -f "/home/username/.ssh/known_hosts" -R "hostname"

Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).
