To do what you want you would need to embed your password in a script in plain text - not good for security! Do you really want to do this?

The above line in the /etc/passwd file gives the following error... (2 Replies)

did a big mistake, changing root entry of /etc/passwd to
root:x:0:0:root:/root:/usr/bin/tmux split-window -v \; attach
as expected, now I can't login as root anymore. sudo ed /etc/passwd etc. doesn't work.
Any idea?

NAME
snmpkey - Create SNMPv3 security keys for the Net::SNMP module
SYNOPSIS
The "snmpkey" utility generates security keys based on a password and an authoritativeEngineID passed on the command line. This key can
then be used by the Net::SNMP module instead of the plain text password when creating SNMPv3 objects.
snmpkey <authProto> <password> <authEngineID> [<privProto> [<password>]]
DESCRIPTION
The User-based Security Model used by SNMPv3 defines an algorithm which "localizes" a plain text password to a specific
authoritativeEngineID using a one-way hash. This resulting key is used by the SNMP application instead of the plain text password for
security reasons.
The Net::SNMP module allows the user to either provide a plain text password or a localized key to the object constructor when configuring
authentication or privacy. The "snmpkey" utility can be used to generate the key to be used by the -authkey or -privkey named arguments
when they are passed to the Net::SNMP "session()" constructor.
The "snmpkey" utility requires at least three command line arguments. The first argument defines which hash algorithm to use when creating
the authKey. Either HMAC-MD5-96 or HMAC-SHA-96 can be specified with the string 'md5' or 'sha' respectively. This choice must match the
algorithm passed to the -authprotocol argument when creating the Net::SNMP object. The second argument is the plain text password that is
to be localized to create the authKey. The third required argument is the authoritativeEngineID of the remote SNMP engine associated with
the Net::SNMP argument -hostname. The authoritativeEngineID is to be entered as a hexadecimal string 10 to 64 characters (5 to 32 octets)
long and can be prefixed with an optional "0x".
The last two arguments are optional and can be used to determine how the privKey will be generated. By default, the fourth argument
assumes a value of 'des' corresponding to the default privacy protocol defined in the User-based Security Model. The Net::SNMP module
supports CBC-3DES-EDE and CFB128-AES-128 as alternatives to the default protocol CBC-DES. These protocols can be chosen by specifying the
string '3des' or 'aes' respectively. This choice must match the protocol passed to the -privprotocol argument when creating the Net::SNMP
object. The last argument can be used to specify the plain text password that is to be localized to create the privKey. If this argument
is not specified, the authKey password is used.
