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.

Hello..
I stink at NIS! :)
Im having a problem with NIS on solaris 2.X. / SPARC
I have some maps that are exported to all clients in the domain. Now I setup a new server and add it as a nis client to the domain. On the NIS server there is a auto_direct map that mounts /usr/local . This is... (4 Replies)
YPINIT(8) BSD System Manager's Manual YPINIT(8)NAME
ypinit -- initialize NIS subsystem
SYNOPSIS
ypinit -c [domainname] [-l server1,...,serverN]
ypinit -m [domainname] [-l server1,...,serverN]
ypinit -s master_server [domainname] [-l server1,...,serverN]
DESCRIPTION
ypinit initializes the files and directories that are required for a NIS client or server.
If domainname isn't specified, the default domain (as returned by domainname(1)) is used.
The following options are available:
-c Create a NIS client. Initializes /var/yp/binding/<domain>.ypservers to contain a list of ypservers for ypbind(8) to connect to.
-l server1,...,serverN
Set the list of client servers from the command line rather than prompting for them interactively. The format is a comma separated
list of server names with no spaces.
-m Create a master NIS server. Generates map data from local files (/etc/master.passwd, /etc/group, etc.).
-s master_server
Create a slave server. Downloads the maps from master_server, which should be the active master NIS server.
To rebuild or refresh the maps for the NIS domain <domain>, change to the /var/yp/<domain> directory and run make.
FILES
/var/yp master NIS directory; contains the template makefiles.
/var/yp/<domain> directory to store NIS maps for <domain>.
/var/yp/binding/<domain>.ypservers
list of NIS servers to bind to.
