Interface - HP NonStop SSH 544701-014 Reference Manual

name in it. Otherwise, the host key file and user data base cannot be used on the other system. If you purge the
HOSTKEY and SSHCTL files and restart the SSH2 process, a new HOSTKEY and SSHCTL file will be
created using either the value of parameter CUSTOMER or, if that does not exist, the customer name from the
license file.
•
Although a license file is no longer required for NonStop SSH on H and J operating systems, any existing
HOSTKEY and SSHCTL file requires the customer name that was used to create the file. If a license file exists,
the customer name will be extracted from that file (entry SSH2.customer), unless parameter CUSTOMER is set
in which case the value of CUSTOMER is used. If a license file does not exist and an existing HOSTKEY or
SSHCTL file is accessed, the parameter CUSTOMER must be set to the original value for the customer name.
•
The host key uses the DSA algorithm and has a length of 1024 bits. The fingerprint of the host key is displayed
on startup.
•
The public key part of the host key can be exported using the SSHCOM daemon mode command EXPORT
HOST-KEY.
•
If multiple SSH2 processes started from the same subvolume but used for different purposes, then not only
separate SSH database files (configured via SSHCTL) but separate host key files (configured via HOSTKEY)
should be configured. Example: SSH for maintenance and public network.
Default
If omitted, SSH2 will use a file name of HOSTKEY.
Example
HOSTKEY $SYSTEM.SSH2.SSHKEY

INTERFACE

Use this parameter to specify the local IP address SSH2 should listen on for incoming SSH connections.
Parameter Syntax
INTERFACE ip-address
Arguments
ip-address
Specifies the local IP address SSH2 should listen on.
Default
If omitted, SSH2 will listen on all local IP addresses of the configured TCPIP process (SUBNET), which corresponds to
INTERFACE value 0.0.0.0 or, in case of IPv6, 0::0.
Examples
INTERFACE 10.0.0.196
INTERFACE fe80::a00:8eff:fe00:d14e
INTERFACE ::FFFF:222.1.41.90
Considerations
•
The value must be set consistent with the value of parameter IPMODE.
•
If IPMODE parameter is set to DUAL, then an IPv6 address must be used (IPv4-mapped IPv6 address for IPv4
addresses)
