SSH Reference Manual

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>
[, ADDRESSES <ip_or_dns> [,<ip_or_dns>,]...]
[, PORT <portnr>]
[, PUBLICKEY {FINGERPRINT <fingerprint> |
FILE <file name>} ]
[, ALGORITHM {SSH-DSS | SSH-RSA} ]
[, COMMENT { <word> | "<word> <word> ..." }]
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.
Only the SUPER.SUPER user (unless explicitly denied in OBJECTTYPE USER record) or those configured with full
SSHCOM access can delete a known host entry for other users.
<knownhost-name>
The name of the known host to be deleted.
FREEZE KNOWNHOST
The FREEZE KNOWNHOST command freezes a known host. 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.
The command has the following syntax:
FREEZE KNOWNHOST [<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 FREEZE 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.
Only the SUPER.SUPER user (unless explicitly denied in OBJECTTYPE USER record) or those configured with full
SSHCOM access can freeze a known host entry for other users.
