11. NIS (Network Information Systems)

NIS: Centralizing the users, passwords, hosts & networks.

Issue 1: How to update the newly added users (or mapping information)

A: cd var/yp/usr/ccs/bin/make

Issue 2: When NIS user unable to login?

 A: simply I check out the user, pwds

Issue 3: disable the NIS services?

A: simply start and stop the services which are related to NIS (or)

Simply update the maps.

NOTE: In my organization LDAP configuration used so very less to get the problems

-          NIS information stored in ‘nis maps’

-          All maps located in ‘/var/yp/domain name’ file

-          Configure the maps on server

#ypint  -m

10. Zones (Real Time)

10. Zones

Note: till now I did not get any issues on zones.

Two commands

# zoneadm

# zonecfg                    (create/delete the zone)

-          we can create upto 8192 zones bt editing the file

-          # cat /kernel/drv/md.conf

 nmd = 8192 ( by default nmd=128)

two types of zones

1. global zones

2. non global zones

-          global zone id always zero ‘0’

-          # zoneadm list –vc

-          Id =0

Two types of non global zones

1. whole root zone (morethan 300MB)
2. sparse root zone (100MB)

zone stages:

1. configuration – incomplete
2. install
3. ready – running
4. shutdown (halt)

for config 4 command

1. create
2. install
3. ready
4. boot

for unconfig

1. halt
2. uninstalled
3. delete

Issue 1:

Reboot the zone when patches are applied to non – global zone

Container: adding the hard ware resources to the zone

Branded zone: we can install other OS to zone also instead of one OS

Zone config file:

# cd /etc/zones

# ls

Zone login console:

# zlogin –C orazone                (C : console

# zonename                 ( to find out which zone)

From global rebooting non-global

# zoneadm –z orazone reboot

# arp –a           (to see the IP address of global from non global)

# arp –a | grep –i SP

Passwd breaking for non-global zone:

# cd /zoneconfig FS name

# cd /root

# vi etc/shadow

And remove the passwd fields

To see what ever config in zone till now:

# zonecfg –z arazone info

Adding ‘FS’ to zone:

To remove the FS resource

# zonecfg –z orazone remove fs dir=/zz

# zonecfg –z orazone info

# zonecfg –z orazone

LOFS: loop back file system:

Giving the multiple mount points to a single file system

How to add:

# zonecfg –z orazone

Zone: orazone> add

Add attr add copped-memory  add net add fs

Client system (NFS)

# mkdir /nn

# mount –F nfs 192.168.1.10: /sai  /nn

# showmount –e 192.168.1.10

# df –F nfs

Issue 1:

ü  Deamons

ü  Versions -4

ü  How to share the resources (or) files (or) directories

ü  How to permanent the share files & directories in server

Client side:

How to mount the shared files & directories in client

How to permanent

Issue 2: already shared files & directories, if we unshared it will throw

Client side: RPC timed out, can’t stat error

That time we can’t share

Cant statvfs: /nn: no such file /directory

And some times there may be a chance to hang the output of df –h (or) df –k.

A: simply I checked out the NFS shared file information

(or)

Simply I checkedout etc/vfstab

If NFS shared file

# shareall on client & server side

# svcs –a | grep nfs/client

# svcadm enable nfs/client

Restart the deamon nfs4cbd

From # cd /usr/lib/nfs

# ./nfs4cbd                  (it will run for communicate server to client

# ./nfs4cbd start

To see mount points of client from server side

# dfmounts

#rmmounts

9. NFS (Network File System) - Real Time

                                    9. NFS (network file system)

1. # cat /etc/dfs/fstype

2. # cat /etc/dfs/sharetab         (like mnttab)

3. # cat /etc/dfs/dfstab                        (like vfstab)

To see deamons of nfs:

# ps –ef | grep nfs

# share                         // read the entries from /sharetab

# shareall                     // read the entries from /dfstab

When we apply #share, then /sharetab automatically updates.

To make read only:

# share –F nfs –o ro /sai

# share

Issue 1:

If service is disable, it will not share

A: check out the services of NFS &

#svcs –a |grep nfs

If network pbm:

# svcadm enable network/nfs/server

#share

If deamon pbm:

Just start the deamon

# cd /usr/lib/nfs

# file mountd

#./mountd

To see port num

# netstat –a | grep –i nfs

8. Patch Management (Real Time)

8. Patch management

# showrev –p

To know NIC speed

# dladm show-dev

Or

#ndd –get /dev/e1000g0 link-speed

#ndd –get /dev/e1000g0 link-status

#ndd –get /dev/e1000g0 \?     //to see all options \?

Assigning the IP:

To findout the nic information

# cat /etc/path_to_inst  | grep –i net

Or

# dladm show-dev

Assigning the IP & plumb:

# ifconfig e1000g0 plumb

#ifconfig –a

# ifconfig e1000g0  192.168.1.10

# ifconfig e1000g0  192.168.1.10 up

Unplumbed IP

# ifconfig –a

# ifconfig e1000g0  192.168.1.10  down

# ifconfig e1000g0  unplumb

To permanent the IP address

We need to edit 4 files

1. #cat /etc/hosts
2. # cat /etc/inet/ipnodes
3. # cat /etc/nodename
4. # cat /etc/hostname.nicname

# cat /etc/hostname.e1000g0

To see all ports:

# netstat -a
