<knownhost-name>
The name of the known host to be added.
ADDRESSES
Specifies an IP address, a DNS name or a comma separated list of IP addresses or DNS names enclosed in parentheses,
which identify the target host, which the publickey associated with this knownhost entry is accepted from.
PORT
The target port number of the remote host associated with this known host entry.
PUBLICKEY
Either the MD5 fingerprint of the known host's public key or the name of a file that contains the remote host's public
key. The fingerprint can either be specified in MD5 or bubble-babble format.
ALGORITHM
Specifies the key exchange algorithm to be used. Valid values are SSH-DSS and SSH-RSA.
COMMENT
An optional comment associated with the known host entry. The comment must be enclosed in double quotes if it
contains spaces.
FROZEN
If the FROZEN attribute is set, the known host entry is added but frozen. A local SFTP client cannot connect to the
remote host on the specified port until this known host entry is thawed using the THAW KNOWNHOST command.

ALTER KNOWNHOST

The ALTER KNOWNHOST command changes one or more attributes of an existing known host and has the following
syntax:
ALTER KNOWNHOST [<system-user-name>:]<knownhost-name>
The individual attributes are identical as in the ADD KNOWNHOST command, please see that section for details.
Only the SUPER.SUPER user (unless explicitly denied in OBJECTTYPE USER record) or those configured with full
SSHCOM access can alter a known host entry for other users.

DELETE KNOWNHOST

The DELETE KNOWNHOST command deletes a known host from the database and has the following syntax:
DELETE KNOWHOST [<system-user-name>:]<knownhost-name>
The individual attributes have the following meaning and syntax:
<system-user-name>
A valid GUARDIAN user who owns the known host entry in the user database. If <system-user-name> is omitted, either
the user being set with a previously issued ASSUME USER command or the issuer of the ADD KNOWNHOST
command will be used as the default. If <system-user-name> is specified, it MUST be followed by a ':' to separate it
from the known host name that follows.
