General Security Commands
security
Syntax security
Context config>system
Description This command creates the context to configure security settings.
Security commands manage user profiles and user membership. Security commands also manage
user login registrations.
ftp-server
Syntax [no] ftp-server
Context config>system>security
Description
This command enables FTP servers running on the system.
FTP servers are disabled by default. At system startup, only SSH server are enabled.
The no form of the command disables FTP servers running on the system.
hash-control
Syntax hash-control [read-version {1 | 2 | all}] [write-version {1 | 2}]
no hash-control
Context config>system>security
Description
Whenever the user executes a save or info command, the system will encrypt all passwords, MD5
keys, etc., for security reasons. At present, two algorithms exist.
The first algorithm is a simple, short key that can be copied and pasted in a different location when
the user wants to configure the same password. However, because it is the same password and the
hash key is limited to the password/key, even the casual observer will notice that it is the same key.
The second algorithm is a more complex key, and cannot be copied and pasted in different locations
in the configuration file. In this case, if the same key or password is used repeatedly in different con-
texts, each encrypted (hashed) version will be different.
Default
all — read-version set to accept both versions 1 and 2
Parameters
read-version {1 | 2 | all} — When the read-version is configured as "all," both versions 1 and 2 will
be accepted by the system. Otherwise, only the selected version will be accepted when reading con-
figuration or exec files. The presence of incorrect hash versions will abort the script/startup.
write-version {1 | 2} — Select the hash version that will be used the next time the configuration file
is saved (or an info command is executed). Be careful to save the read and write version correctly, so
that the file can be properly processed after the next reboot or exec.
