What do you know about the setup of this machine if mail.debug is sent to /var/log/authlog?
*** The answer here is that in the /etc/hosts file, the local host is aliased as "loghost", therefore the M4 processer evaluates LOGHOST as True, and sends it to /var/log/authlog

**-- server1:/var/ - nfs - yes nointr, hard
91. What are benifits of NFS?
**Files are located in centralized locations. You can make a copy of a file accessible to many users or systems simultaneously. This is an especially useful feature with 'home' directories or common data files.Systems can share one or more software packages that are located in a central location.
**This reduces the disk space requirements for individual systems
**Remote file sharing is transparent to user and to any applications, because these resources appear as if they were resident on local systems
**NFS provides file sharing in a heterogeeneous (many different O/S's..,unix, windows, solaris) environment, potentially containing many different operating systems.
92. Know .
NFS server: A system that contains the file resources to be shared with other systems on the network

96.***dfshares displays shared resources for local server pg. 6-14/15
97.***dfmounts displays shared resource and clients mounting the resource for the local server.
98. How do you stop and start NFS daemons?
#/etc/init.d/nfs.server stop
#/etc/init.d/nfs.server start
14) When doing a remote mount over the network, what options(choose 2) would allow the client trying to mount to reboot if the mount is hanging?
--nointr
--**intr **
--soft
--**hard **
--bg
--fg

44. Fill in - nsswitch.nis. What template in /etc is used for nis name service?
***--nsswitch.nis. JUST TYPE IN ...(NOT /etc/.....)
48. Understand this - hosts: nis [NOTFOUND=return] files.

modify the :
" /var/yp/Makefile " by changing the
DIR=/etc. to DIR=/yourchoice
PWDIR=/etc. to PWDIR=/yourchoice
116. Create a NIS Server:
**copy /etc/nsswitch.nis to /etc/nsswitch.conf
**Choose NIS Domainname by executing #domainname
or modifying the /etc/defaultdomain
**touch /etc: bootparams ethers locale timezone netgroup netmasks
(" BELT,NN "

**# /usr/lib/netsvc/yp/rpc.yppasswdd /etc/passed -m passwd
119.Know that :
** The "first time " you build a new map, the slave servers do not know of its existence and so the push process attempts fail.
**Send an interrupt (Control-C) to build process when the push process hangs,
**execute the "ypxfr" command on hte map from the slave servers to complete the build process.
112. NIS Master Server
**Contain original /etc ASCII files used to build NIS maps (Slave servers do NOT)

required to do administration, including reboots, backups...
*Brings all tools together in one location
*Can manage all SMC servers from one location
* Once a new application is added to a SMC server, anyone can run application.

**Files are located in centralized locations. You can make a copy of a file accessible to many users or systems simultaneously. This is an especially useful feature with 'home' directories or common data files.Systems can share one or more software packages that are located in a central location.
**This reduces the disk space requirements for individual systems
**Remote file sharing is transparent to user and to any applications, because these resources appear as if they were resident on local systems
**NFS provides file sharing in a heterogeeneous (many different O/S's..,unix, windows, solaris) environment, potentially containing many different operating systems.
92. Know .
NFS server: A system that contains the file resources to be shared with other systems on the network

44. Fill in - nsswitch.nis. What template in /etc is used for nis name service?
***--nsswitch.nis. JUST TYPE IN ...(NOT /etc/.....)

49. What daemon answers ypbind request from clients?
***--ypserv
51. Know that you have to edit the /etc/hosts file on the NIS slave server.

***/usr/lib/netsvc/yp/ypstart
118. How to update password map on server:
**# /usr/lib/netsvc/yp/rpc.yppasswdd /etc/passed -m passwd
119.Know that :
** The "first time " you build a new map, the slave servers do not know of its existence and so the push process attempts fail.
**Send an interrupt (Control-C) to build process when the push process hangs,
**execute the "ypxfr" command on hte map from the slave servers to complete the build process.
112. NIS Master Server
**Contain original /etc ASCII files used to build NIS maps (Slave servers do NOT)
**Provide single point of control for entire NIS domain
**Contain NIS maps generated from ASCII files
**Easy to setup

required to do administration, including reboots, backups...
*Brings all tools together in one location
*Can manage all SMC servers from one location
* Once a new application is added to a SMC server, anyone can run application.
