Prevent accidental push of yp maps from slave servers
To prevent an accidental "cd /var/yp; make all" from being executed on an NIS slave server, I found a helpful hint from an instructor in a Solaris class. Just rename the /var/yp/Makefile to Makefile.orig. You will get an error message when trying to execute the "make all" on a slave server.
I was practicing writing simple loops as I am a new bash user and I created this script, which turned out to be an endless loop where the echo output does not stop and I do not see where my mistake is.
#!/bin/bash
echo 'enter a number from 1 to 100'
read number

I think the libc.so is shared between processes, because it is a shared library and OS is engaged for saving memory.
But, below, the maps of bash, shows r-xp and r--p rw-p attributes to libc.so which mean private memory space.
Can anybody explain this for me?

I had created a root account when I installed the Centos 5 into my system.
But now the problem I'm facing is that I accidently deleted the root user account in my system.
Is there a way to recreate the root account in the system now, without reinstalling the OS?
Pls help. (1 Reply)
Hi,
Is there a way to protect users from deleteing their .profile ?
For the majority of our users I created a captive login by a .profile that starts a menu-script. In this menu a user can only start our applications and logoff. This prevents users from getting to the unix-prompt.

nissetup(8) System Manager's Manual nissetup(8)NAME
nissetup, ypsetup - Sets up the Network Information Service (NIS) environment
SYNOPSIS
/usr/sbin/nissetup
/usr/sbin/ypsetup
DESCRIPTION
The nissetup (formerly ypsetup) script configures and runs NIS on your system. You can use nissetup to initially set up your NIS configura-
tion, to change your current NIS configuration, or to remove your NIS configuration. NIS provides a distributed data lookup service for
sharing data among networked systems.
Before running nissetup, make sure that your system is connected to a local area network and that the network is configured and running.
You must know the name of your NIS domain and your system's role in the domain (master server, slave server, or client).
Security Note
You invoke nissetup from the SysMan Menu. See sysman(8) for more information.
When using the nissetup script to set up a NIS server that is running with enhanced security, you must answer yes to the question about
locking the domain name and authorized servers (the ypbind -S option). If you are setting up a master server, the server is bound to itself
(done by default). If you are setting up a slave server, the server is bound to itself done by default) and optionally to the master server
and any other slave servers.
If your system will be the master server for your NIS domain, be sure no other master exists for your domain and that the NIS database
files are in the /var/yp/src directory.
Note
Remove the root entry, if it exists, from the passwd database file.
If your system be will be a slave server or client, be sure a master server is already set up for your NIS domain.
FILES
Specifies the command pathname NIS parameters pertinent to a specific system
Default NIS Databases
In the /var/yp/src directory, the default databases are: Group database Host database Sendmail alias database Network group aliases data-
base Network database Password database Protocol database RPC database Service database
