I created a user which will have permission to su to root, but now i don't know where and what to modify to disable root login?

Hello!
I'm going through security checklist for AIX 5.3 and i just can't disable remote login for root through ssh.
What i did:
- in /etc/security/user i added a line:
rlogin = false
which works fine when i try to login through telnet
- after installation of openSSH i edited... (3 Replies)
Ok guys,
I'm just getting back to this amongst several other projects, but I thought I'd re-address it. I'm creating the script to disable windows from the previous login under 10.7. In order to do this it seems I need to create the same script for applications that launch and create the... (6 Replies)

I have a v490 server running Solaris 10.
Everytime I reboot this machine, the console-login service goes to maintainance mode and I have to provide the root password. All the other dependencies are running fine and nothing there in the logs too. To bring it online, I have to enable it manually.

Hello all friends
I recently disable runlevel 1
i want to know , is there any way to disable emergency mode and init mode
init mode means if any user pass kernel parameter at grub i.e init=/bin/bash
then bash shell appears
I want to disable it for security purpose

Hi Guys
After installing my CentOS in virtual machine i am not able to get the graphical mode. By default it is going in TUI mode.
Please help how to get the graphical mode by default.

openssl_genrsa
GENRSA(1) OpenSSL GENRSA(1)NAME
genrsa - generate an RSA private key
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
openssl genrsa [-out filename] [-passout arg] [-aes128] [-aes128] [-aes192] [-aes256] [-camellia128] [-camellia192] [-camellia256]
[-aes192] [-aes256] [-camellia128] [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-f4] [-3] [-rand file(s)] [-engine id] [numbits]
DESCRIPTION
The genrsa command generates an RSA private key.
OPTIONS -out filename
the output filename. If this argument is not specified then standard output is used.
-passout arg
the output file password source. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in openssl(1).
-aes128|-aes192|-aes256|-camellia128|-camellia192|-camellia256|-des|-des3|-idea
These options encrypt the private key with specified cipher before outputting it. If none of these options is specified no encryption
is used. If encryption is used a pass phrase is prompted for if it is not supplied via the -passout argument.
-F4|-3
the public exponent to use, either 65537 or 3. The default is 65537.
-rand file(s)
a file or files containing random data used to seed the random number generator, or an EGD socket (see RAND_egd(3)). Multiple files
can be specified separated by a OS-dependent character. The separator is ; for MS-Windows, , for OpenVMS, and : for all others.
-engine id
specifying an engine (by its unique id string) will cause genrsa to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default for all available algorithms.
numbits
the size of the private key to generate in bits. This must be the last option specified. The default is 512.
NOTES
RSA private key generation essentially involves the generation of two prime numbers. When generating a private key various symbols will be
output to indicate the progress of the generation. A . represents each number which has passed an initial sieve test, + means a number has
passed a single round of the Miller-Rabin primality test. A newline means that the number has passed all the prime tests (the actual number
depends on the key size).
Because key generation is a random process the time taken to generate a key may vary somewhat.
BUGS
A quirk of the prime generation algorithm is that it cannot generate small primes. Therefore the number of bits should not be less that 64.
For typical private keys this will not matter because for security reasons they will be much larger (typically 1024 bits).
