One way (although not incredibly secure,) is:
Now, the above assumes some things, like you're using ssh2, your admin hasn't disabled you from doing that, that you are not breaking policy by doing that, etc.

ssh-keysign
ssh-keysign(1M)ssh-keysign(1M)NAME
ssh-keysign - ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication
with SSH protocol version 2. This signature is of data that includes, among other items, the name of the client host and the name of the
client user.
ssh-keysign is disabled by default and can be enabled only in the global client configuration file /etc/ssh/ssh_config by setting Host-
basedAuthentication to yes.
ssh-keysign is not intended to be invoked by the user, but from ssh. See ssh(1) and sshd(1M) for more information about host-based authen-
tication.
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, readable
only by root, and not accessible to others. Because they are readable only by root, ssh-keysign must be set-uid root if host-based
authentication is used.
ssh-keysign will not sign host-based authentication data under the following conditions:
o If the HostbasedAuthentication client configuration parameter is not set to yes in /etc/ssh/ssh_config. This setting cannot be overri-
den in users' ~/.ssh/ssh_config files.
o If the client hostname and username in /etc/ssh/ssh_config do not match the canonical hostname of the client where ssh-keysign is
invoked and the name of the user invoking ssh-keysign.
In spite of ssh-keysign's restrictions on the contents of the host-based authentication data, there remains the ability of users to use it
as an avenue for obtaining the client's private host keys. For this reason host-based authentication is turned off by default.
